Value added Definition

In common days we oftenly heard value added word. This word oftenly using as a technical term used in economic. But in this part i will explained about Definition of Value Added in Agriculture terms.

Velue added means
The enhancement added to a product or service by a company before the product is offered to customers.
So it means creating a competitive advantage by bundling, combining, or packaging features and benefits that result in greater customer acceptance. By this step a raw material from field or all agricultural product will increase their price and give more benefits to the costumers.

Environmentally friendly jets engine with biofuels

David Shonnard, Robbins Chair Professor of Chemical Engineering, analyzed the carbon dioxide emissions of jet fuel made from camelina oil over the course of its life cycle, from planting to tailpipe. “Camelina jet fuel exhibits one of the largest greenhouse gas emission reductions of any agricultural feedstock-derived biofuel I’ve ever seen,” he said. “This is the result of the unique attributes of the crop–its low fertilizer requirements, high oil yield, and the availability of its coproducts, such as meal and biomass, for other uses.”

Camelina sativa originated in Europe and is a member of the mustard family, along with broccoli, cabbage and canola. Sometimes called false flax or gold-of-pleasure, it thrives in the semi-arid conditions of the Northern Plains; the camelina used in the study was grown in Montana.

Oil from camelina can be converted to a hydrocarbon green jet fuel that meets or exceeds all petroleum jet fuel specifications. The fuel is a “drop-in” replacement that is compatible with the existing fuel infrastructure, from storage and transportation to aircraft fleet technology. “It is almost an exact replacement for fossil fuel,” Shonnard explained. “Jets can’t use oxygenated fuels like ethanol; they have to use hydrocarbon replacements.”

Shonnard conducted the life cycle analysis for UOP LLC, of Des Plaines, Ill., a subsidiary of Honeywell and a provider of oil refining technology. In an April 28 release, it cited Boeing executive Billy Glover, managing director of environmental strategy, who called camelina “one of the most promising sources for renewable fuels that we’ve seen.”

“It performed as well if not better than traditional jet fuel during our test flight with Japan Airlines earlier this year and supports our goal of accelerating the market availability of sustainable, renewable fuel sources that can help aviation reduce emissions,” Glover said. “It’s clear from the life cycle analysis that camelina is one of the leading near-term options and, even better, it’s available today.”

Because camelina needs little water or nitrogen to flourish, it can be grown on marginal agricultural lands. “Unlike ethanol made from corn or biodiesel made from soy, it won’t compete with food crops,” said Shonnard. “And it may be used as a rotation crop for wheat, to increase the health of the soil.”

Tom Kalnes is a senior development associate for UOP in its renewable energy and chemicals research group. His team used hydroprocessing, a technology commonly used in the refining of petroleum, to develop a flexible process that converts camelina oil and other biological feedstocks into green jet fuel and renewable diesel fuel.

As to whether we will all be flying in plant-powered aircraft, his answer is, “It depends.”

“There are a few critical issues,” Kalnes said. “The most critical is the price and availability of commercial-scale quantities of second generation feedstocks.” Additionally, more farmers need to be convinced to grow a new crop, and refiners must want to process it.
“But if it can create jobs and income opportunities in rural areas, that would be wonderful,” he said.

Earth Hour and Agroindustrial Bio Product

Climate change is one threat to life on Earth is the most significant. One way to reduce the acceleration of global warming is to make each individual make lifestyle changes. To achieve this change, we as an organization must be able to show that the change is simple and easy.

Human dependence that in fact the electricity comes mostly from power plants and fossil fuel out of CO2 or greenhouse gases has caused a dramatic increase in the average temperature of Earth, causing the sea level rise, the long drought and storms, and massive changes to the environment that has become the source of our lives.

Solutions
"An activity aimed at building community involvement or invite a small area of action that can bring a big change."

What is Earth Hour
EARTH HOUR is one of WWF's campaign, the largest conservation organization in the world, a global initiative that invites individuals, business practitioners, government, and other public sectors around the world to participate turned out the lights (just) in 1 hour, on Saturday, 27 March 2010 at 20:30 to 21:30 (local time).

EARTH HOUR campaign began with a collaboration between WWF-Australia, Fairfax Media and Leo Burnett for the city of Sydney, Australia, with the goal of reducing greenhouse gases in the city as much as 5% in 2007. The success of this campaign is expected to be adopted by society, communities, businesses and other governments around the world so that all citizens of the world can help show that an individual action that is easy even if done in bulk will make our life on Earth for the better.

What influence Earth Hour
In 2008, 50 million people in 35 countries turned off the lights in action to support EARTH HOUR.
On March 28, 2009, hundreds of millions of people in more than 4000 cities and towns in 88 countries around the world turned off the lights to support EARTH HOUR. EARTH HOUR 2009 became the largest environmental movement in history.

Earth Hour and Agroindustry Bio-Product
Actually, the main idea of this campaign is to raise public awareneess of our environtmental condition. Earth Hour is also strategic momentum to :
  1. Reminding the public that climate change also comes from power plants using fossil fuel
  2. Promote energy efficiency in cities with populations and high electricity consumption.
  3. Creating and sparked public awareness about energy-efficient lifestyle in other big cities in World, the crisis of electricity supply and distribution, and also potential sources of electricity in Big Cities to meet the needs of local communities, in a broader perspective can also stimulate changes in behavior and incentives for the economy. (www.earthhour.wwf.co.id)
In other side, the system of Agroindustry is always making something new to add the value of Agricultural Product. Many Agro Industries is trying to make bio-product to reduce the emmision of Gas CO2 and decrease the usage of fossil fuels.

In now days, there are many agro industrial bio product that can be uses to reduce a Global Warming process. This product are like bio-plastic that can be degradable by it self, bio-fuels (bioethanol, biodiesel, biogases, biobiokerosene) that claimed have complete combustion so it can decrease the CO gases and other bio products that are greener.

This mean by using bio-product we we have participated in the civilizing Agroindustry, and participated in environmental campaigns without having to turn off the lights. (even turned off the lights in the Earth Hour is much better)

Agroindustry subsystem

(source: Bungaran Saragih ,Former Minister of Agriculture of the Republic of Indonesia ;
Professor of the Department of Social Economy, Faculty of Agriculture, IPB)

According Bungaran Saragih, there are 4 sub-systems in the world of Agroindustry. 4 sub-systems are:

(1) Sub-system of agri-upstream (up-stream Agroindustry),
ie industries that produce capital goods for agriculture, such as industry Germination / seedlings, plants, animals, fish, agrochemical industry (fertilizer, pesticides, medicines, vaccines ternak. / fish), industrial equipment and agricultural machinery (agro-automotive );
(2) Sub-primary agricultural systems (on-farm Agroindustry),
ie cultivation activities that produce primary agricultural commodities (crops farming, horticultural farming, farming medicinal plants (bio), plantation, animal husbandry, fisheries, and forestry business);
(3) Sub-system downstream Agroindustry (down-stream Agroindustry),
the industries that process agricultural primary commodities into processed products such as industrial makanan. / beverage, food industries, industrial goods of natural fibers, the pharmaceutical industry, bio-energy industry etc. and
(4) Sub-system provider of Agroindustry (services for Agroindustry) such as credit,
transportation and warehousing, R & D, human resource education, and economic policy

With the scope of the Agroindustry system development, the construction industry, agriculture and services reinforce each other and converging at the production of agri products the market needs.

In the Agroindustry system perpetrator is the Agroindustry enterprises (firm) of farming families, business groups, small business, medium business, business cooperatives and corporations, both in the sub-systems downstream Agroindustry, sub-systems on farm, Agroindustry sub-system upstream and the sub-systems for Agroindustry service providers. Therefore, the government is going to grow and develop and strengthen Agroindustry enterprises through a variety of policy instruments owned. The government is no longer the executor, but act as a facilitator, regulator and promoter of development and Agroindustry systems.

Algae the solution of Energy

According to research results, from each hectare Jatropha curcas plantation, in a year, can only produce 1500 liters of oil. This is better than radish seeds that produce 1000 liters and cabbage seeds (mustard) 1300 liters. However, the distance is still less superior than coconut (2200 liters), oil (Crude Palm Oil CPO) (5800 liters), and even more productivity from algae that reach 40,000 to 120,000 liters per hectare per year. Productivity of algae truly remarkable even than CPO. In addition to the great productivity, biofuel from algae is one solution in fulfilling the energy needs so as not to conflict with the fulfillment of their food needs.

Bioenergi

The availability of ethanol and biodiesel at the fuel pump is becoming more prevalent. Rising fuel prices, environmental concerns, pressures for oil independence, and Federal energy policy are creating a strong market for renewable energy.
Bioenergy is renewable energy derived from biological sources, to be used for heat, electricity, or vehicle fuel. Biofuel derived from plant materials is among the most rapidly growing renewable energy technologies. In the United States, corn-based ethanol is currently the largest source of biofuel as a gasoline substitute or additive. Growing biofuel demand has implications for the U.S. agriculture sector and rural communities.

Agroindusty Marketing

Although forest, agricultural land and we continue to exploit the sea was still productive. We proudly claim as an agricultural country. We are also proud often "drift" when foreigners praise the fertility of our country. In fact this is so, although the level of fertility and productivity decline.
Although our country fertile, but we still have to import soybeans for tempe manufacture, production of tomatoes for sauce, wheat for noodles, garlic for a variety of herbs and other agricultural products to traditional herbal medicine industry. We do need to have tdak ideals of self-sufficiency for all agricultural products. Era was not the case anymore. Consumers are shifting needs and desires. Consumers appreciate quality assurance, comfort and uniqueness of products.
Agro-industry is an important solution to bridge the consumer desires and characteristics of agricultural products are varied and could not be saved. Range of agro-industries have a very broad sense. From the very soft form of post-harvest processing such as the creation of only salted fish preservation technology should have reached a high value added agricultural products in which the extracts and combined with other products in sepert perfume industry.
Wheat will be appreciated more expensive when it's milled into flour, and will be even higher keitika processed into bread. The price of bread will also be more expensive if given additional service delivery to consumer homes by using a car or a type of bread served at the coffee shop five-star hotel.
One time in one of the shopping center I was impressed with the traders who were using menjula corn wheelbarrow. Boiled sweet corn that was removed from the cob plus sweetened condensed milk and vegetable oil and then beaten, whipped and served in a fancy plastic cups, hargannya Rp. 6000, - while the price of corn on the cob at the summit area only Rp. 1000, -.Similarly, fishermen who catch fish price per kilonya only a few thousand dollars will be multiplied three or four times when they have been cleaned up and sold in supermarkets, especially if it could be processed and canned sardines.
Similarly, logs from the forests of Borneo that are already sorted and sorted to guarantee the quality will be appreciated more expensive when it arrived in surabaya especially when it is exported to Japan. And will be more appreciated when it diijadikan furniture.
Various examples above illustrate the extent of the range will be very understanding agro-industries. Products "original" variety of agro-industries in the above examples are sardines and plywood. What about flour or bread that is served hotel? I completed my undergraduate education in the agroindustrial majors sapai tecnology and today I still enjoy the endless debate about the definition of agro-industry among agricultural pafkar visit not subside. In my understanding, agro-industry is mebrei industrial added value of agricultural products in a broad sense, including seafood, hasilk forests, livestock and fisheries.



Value added in typical agricultural products in various forms provided meberi persepis higher value in the minds of consumers. The simplest is to improve physical appearance through sorting and quality assurance. Consumers will perceive a low in fish catch of fishermen who still what they are; eg mixed among small fish, big fish and other seafood. The next added value comes through the storage and transportation. Fish are sold by auction at Muara Karang fish market will be valued more expensive when it is presented in a clean condition and placed in cooler Paserba Carrefour.
Value-added agricultural products can be improved through processing industry. Only in the context of the industry today do not have to push the meaning of the same goods produced in bulk. When consumers are increasingly demanding, the industry must be designed and customization demands of consumers adjust. Industry today must be able to provide a variety of products according to demand even a small group of individual consumers.
Basically the added value is not measured by what has been done including all the costs that must be measured from dikeluarakan but the perception of value in the minds of consumers.Because the value added dikur with consumer perception, the role of marketing to include the brand becomes important. The same bread can be appreciated more expensive brands that are sold with Holland Bakery, Delicius, or Sari Roti. Kopi Kapal Api, Kibif meat, cooking oil or samapai Bimoli sambal ABC valued more highly by consumers is not just for high-quality manufacturing processes, but because of hard work to build brand and communicate it to consumers.
Consumers are believed to perception. So if we can give a higher perception of the value creation and equipped with the right marketing applications will be emberi agroindustrial larger donations. During this agricultural commodities are often beaten Gonjang ganjing price drop because the supply abundant. Agro-industries could be a means of escape from the situation, commodity-like traps.
Awards should be given not because of the abundant production levels as a result of such fertile soil Koes Plus said but because the success of adding value higher. Marketing of agro-industries are yet to be more intensified again.

The Impact of Agroindustries

Oil Palm: The Expansion of Another Destructive Monoculture

by Ricardo Carrere

Over the past few decades, oil palm plantations have rapidly spread across the South. They are causing increasingly serious problems for local peoples and their environment, including social conflict and human rights violations. In spite of this, a number of actors -national and international- continue actively to promote this crop, against a background of growing opposition at the local level.

Basic Facts

The oil palm (Elaeis guineensis) is native to West Africa, where local populations have used it to make foodstuffs, medicines, woven material and wine. Today's large-scale plantations are mostly aimed at the production of oil (which is extracted from the fleshy part of the palm fruit) and kernel oil (which is obtained from the nut).

Oil palm plantations composed of specially selected and cloned varieties of palm trees start to produce fruit after four to five years and reach maturity and the highest rate of productivity when the trees are 20 to 30 years old. The fruit bunches, each weighing between 15 and 25 kgs, are made up of between 1000 and 4000 oval-shaped fruits, measuring some three to five cms long.

Once harvested, the fleshy part of the fruit is converted into oil through a series of processes, while the palm kernel oil is extracted from the nut itself. The processing of the crude oil gives rise to two different products: 1) palm stearin and 2) palm olein. The stearin (which is solid at room temperature) is used almost entirely for industrial purposes such as cosmetics, soaps, detergents, candles, lubricating oils, while the olein (liquid at room temperature) is used exclusively in foodstuffs (cooking oil, margarines, creams, cakes and pastries).

Oil Palm Plantations around the World

Oil palm plantations are being established principally in tropical regions where, by 1997 they occupied 6.5 million hectares and produced 17.5 million tonnes of palm oil and 2.1 million tonnes of palm kernel oil.

In Asia, the two main oil palm producing countries are Malaysia and Indonesia (both with more than two million hectares of plantations), which have become the world's principal producers of palm oil. Malaysia generates 50 per cent of world production (of which 85 per cent is exported), while Indonesia is the next largest producer with almost 30 per cent of global production (of which 40 per cent is exported). However, other countries are joining them in large-scale oil production. The most important of these are Thailand (with more than 200,000 hectares) and Papua New Guinea (which is the world third-largest palm oil exporter). Ambitious plans also exist for the Philippines, Cambodia and India, as well as the Solomon Islands.

In Africa it is difficult to obtain precise figures for industrial plantation areas, due to the fact that the oil palm is native to many West African countries. For instance, in the case of Nigeria, production is obtained from an area of three million hectares of oil palm, among which there are some 360,000 hectares of industrial plantations. Other countries also hold large areas covered by oil palms, such as Guinea (310,000 ha) and Congo Democratic Republic (formerly Zaire) (220,000), with important areas of industrial plantations particularly in Ivory Coast (190,000), Ghana (125,000), Cameroon (80,000), Sierra Leone (29,000), and smaller areas in Benin, Burundi, Central African Republic, Republic of Congo, Equatorial Guinea, Gabon, Gambia, Guinea Bissau, Liberia, Senegal, Tanzania, Togo and Uganda.

In Latin America, oil palm plantations are covering increasing areas in Ecuador (150,000 ha), Colombia (130,000) and Brazil (circa 100,000), as well as spreading over numerous other countries such as Honduras (50,000), Venezuela (30,000), Costa Rica (30,000), Peru (15,000), Guatemala (15,000), Dominican Republic (9,000), Nicaragua (4,000), Mexico (4,000) as well as areas in Panama, Suriname and Guyana.

Social and Environmental Impacts

As the areas under plantations increase, so do the negative impacts on the environment and on local societies. This is because, as is the case with monoculture plantations of pine and eucalyptus, the problem is not the tree itself but the plantation model under which it is grown.

Yet the promoters of this model insist on presenting palm plantations as a solution to unemployment problems and even try to demonstrate environmental benefits. The Colombian oil palm producers' federation puts it thus: "oil palm plantations are forests which protect our ecosystems". At the same time, a director of the International Finance Corporation (the branch of the World Bank which grants loans to the private sector), stated that the establishment of IFC-financed oil palm plantations in Ivory Coast "would lead to more employment and higher living standards [and] promote exports that will earn foreign currency, while supporting agricultural production with maximum sensitivity to the environment" (Africa News Online). A Malaysian minister went so far as to declare that palm plantations are in fact "better than the developed nations' pine trees in terms of absorbing carbon gases" (Lohmann 1999).

However, as will be shown in more detail below in the cases of Indonesia, Ecuador and Cameroon, the cultivation of this palm is bringing with it a series of negative impacts affecting people and the environment wherever it is established.

One of the principal impacts is the appropriation of large areas of land which have hitherto been in the hands of indigenous or peasant populations and have provided their livelihoods. This dispossession commonly generates resistance from local people, which is in turn confronted by repression by state forces as well as that of the oil palm companies themselves. The violation of land rights is thus typically followed by other human rights violations, including even the right to life.

Against the background of a world increasingly concerned about the loss of tropical rainforests, it is worth noting that almost all these industrial monoculture oil palm plantations are established in forest areas. Large oil palm plantation companies, which found it convenient to "clear" forest areas for plantations by setting them on fire, were responsible for the gigantic forest fires in Indonesia which shocked the world in 1997. Behind nearly every industrial oil palm plantation lies some such process of deforestation, even if it is usually not so extreme.

The tropical forests which are eliminated to make way for these plantations are the habitat for an enormously diverse range of species. Studies in Malaysia and Indonesia have shown that between 80 per cent and 100 per cent of the species of fauna inhabiting tropical rainforests cannot survive in oil palm monocultures (Wakker 2000). Those few species that do manage to adapt often become "pests" since, having lost their normal food supply, they begin to make a meal of the young palm plants. This in turn necessitates the application of pest "control" methods which include chemical pesticides, causing further damage to biodiversity as well as to fresh water supplies and the health of local populations.

Oil palm monocultures are also associated with soil erosion: forest clearance leaves soils bare and exposed to heavy tropical rainstorms. Erosion, in turn, causes contamination and sedimentation in watercourses, affecting supplies of drinking water and fish on which the local communities depend.

Oil processing industries also have an impact on water quality because of the large quantities of effluents which they release into rivers -2.5 tonnes for each tonne of oil processed. Pollution control laws are seldom complied with.

Despite all this, proponents insist on presenting oil palm plantations as the solution to all the social ills of the region in which they wish to establish them, declaring that they will generate employment, wealth, infrastructure, educational opportunities etc., in an effort to gain the support of local people.

Reasons for Plantation Expansion

Despite their negative impacts, oil palm cultivation continues to expand across more and more countries. The reason for this expansion is, in the first place, that oil palm can be very lucrative for both foreign and domestic investors. Profits are assured by cheap labour, low-priced land, a lack of effective environmental controls, easy availability of finance and other support, and a short growth cycle. In addition, the market is expanding, particularly in the North. Palm oil is the world’s best-selling vegetable oil, representing 40 per cent of the total global trade in edible oils. It is much more important than soya, which represents 22 per cent of the world market (FAS Online 1998). Moreover, it is expected to eventually increase its share of the world market to 50 per cent.

In addition, the fact that oil palm is a crop usually aimed at export markets makes it attractive to governments overwhelmed by external debt and seeking new sources of foreign exchange. External agencies (such as the World Bank, the International Monetary Fund and the United Nations Development Programme) also support oil palm, as do international banks which finance and profit from it. According to one recent study (Wakker 2000), the main Dutch banks (ABN-AMRO Bank, ING Bank, Rabobank and MeesPierson) all maintain close financial links with large oil palm enterprises in Indonesia.

Other, less visible proponents include the overseas conglomerates which benefit from the international palm oil trade. There is nothing new in their method: massive promotion of a crop in order to reduce world prices and stimulate consumption, thus entrenching a commodity in society in a way which ensures profits from marketing and reprocessing. A recent report on palm oil markets from ARAB (a Malaysian-based research and consulting institution) notes that "palm oil prices are generally lower than that of soybean oil" -which "is the dominant oil and serves as the price leader for trade in vegetable oils":

"The existence of the discount for oil palm arises from the large increases in the supply of palm oil in the last two decades and the need for the trader to offer a discount in order to compete with soybean oil in existing and new markets."

The reason for the increase in the supply of palm oil is quite simple: oil palm "is now being planted on a widespread basis in the tropics."

The peoples of the South have suffered from such strategies before, as in the cases of coffee, cocoa, bananas, sugar cane and many other crops. As the prices of such commodities drop, many producers are ruined. At the same time, trade in the industrialized nations benefits and consumption increases.

Further depressing international oil palm prices is the fact that in some markets, palm oil must compete with oils whose price is subsidized by various US and EEC programs, including soybean, sunflower and rapeseed oils (ARABIS 1996). This economic disadvantage is compounded by the fact that "palm oil differs from its major competitors (soybean, sunflower seed, and rapeseed oil) in that it is obtained from a perennial tree crop. Thus its supply is relatively stable as growers will continue to harvest the fruits even during short periods of depressed prices."

While growers of annual oil crops can easily reduce their hectarages during hard times, switching to another crop is not so easy for oil palm growers. Nor are the latter likely to benefit much from price rises, which will cause an increase in the hectarages of competing soybean, sunflower and rapeseed oils. As economists would put it: clearly a lose-lose situation.

In sum, while oil palm plantations are being promoted in the South, prices will be established by a Northern-dominated and subsidized "free market" which is, in fact, anything but free. Industries in the North and elsewhere will be assured of a continuous supply of oil while Southern producers face economic risk.

In the final analysis, the real reasons for the expansion of this crop have nothing to do either with improving living standards in Southern countries nor with environmental protection. Rather, the boom in oil palm plantations mainly serves local elites and the transnational companies with which they ally themselves to obtain mutual benefit. These firms include Unilever, Procter & Gamble, Henkel, Cognis and Cargill. Some are involved in both production and trade. For example, the Anglo-Dutch Unilever produces in Malaysia while acting exclusively as a buyer of oil in Indonesia.

The following studies carried out in Africa (Cameroon), Latin America (Ecuador) and Asia (Indonesia) demonstrate that the local effects of this new wave of investment include an increase in social injustice and in environmental degradation.

Global Warming
On Feb. 2, 2007, the United Nations scientific panel studying climate change declared that the evidence of a warming trend is "unequivocal," and that human activity has "very likely" been the driving force in that change over the last 50 years. The last report by the group, the Intergovernmental Panel on Climate Change, in 2001, had found that humanity had "likely" played a role.

The addition of that single word "very" did more than reflect mounting scientific evidence that the release of carbon dioxide and other heat-trapping gases from smokestacks, tailpipes and burning forests has played a central role in raising the average surface temperature of the earth by more than 1 degree Fahrenheit since 1900. It also added new momentum to a debate that now seems centered less over whether humans are warming the planet, but instead over what to do about it. In recent months, business groups have banded together to make unprecedented calls for federal regulation of greenhouse gases. The subject had a red-carpet moment when former Vice President Al Gore's documentary, "An Inconvenient Truth," was awarded an Oscar; and the Supreme Court made its first global warming-related decision, ruling 5 to 4 that the Environmental Protection Agency had not justified its position that it was not authorized to regulate carbon dioxide.

The greenhouse effect has been part of the earth's workings since its earliest days. Gases like carbon dioxide and methane allow sunlight to reach the earth, but prevent some of the resulting heat from radiating back out into space. Without the greenhouse effect, the planet would never have warmed enough to allow life to form. But as ever larger amounts of carbon dioxide have been released along with the development of industrial economies, the atmosphere has grown warmer at an accelerating rate: Since 1970, temperatures have gone up at nearly three times the average for the 20th century.

The latest report from the climate panel predicted that the global climate is likely to rise between 3.5 and 8 degrees Fahrenheit if the carbon dioxide concentration in the atmosphere reaches twice the level of 1750. By 2100, sea levels are likely to rise between 7 to 23 inches, it said, and the changes now underway will continue for centuries to come.
