20-12-2023 * Modern agriculture is characterized by a farming system that uses chemicals that are harmful to health and the environment. The modern agricultural technology package in question is the use of high-yielding superior varieties, chemical pesticides, chemical/synthetic fertilizers, and the use of agricultural machinery to cultivate the land and harvest the produce. Modern agriculture itself is a form of the green revolution that began to be implemented in Indonesia in the sixties. Initially, the green revolution succeeded in overcoming food insecurity so that Indonesia succeeded in meeting its own food needs, which previously Indonesia was a rice importing country.
The increase in world food production is in line with the use of chemical fertilizers. However, over time many environmental experts have realized that the use of these chemicals can have negative impacts in the form of decreased soil productivity due to the use of chemical fertilizers and damage to the balance of the ecosystem due to the use of pesticides. This situation finally encouraged individuals and groups of organizations to voice the movement to practice environmentally friendly natural farming with various terms such as "organic" or "alternative" and then developed into organic farming as it is today.
The economic prospects of this farming are also quite good along with the changing patterns of human consumption where people prefer healthy food even though it is expensive. Handling of organic waste has so far been conventional by disposing of waste to the Final Disposal Site (TPA). Disposing of waste in this way can pollute the surrounding environment and has no added value. This condition can cause pollution in the form of a foul odor from the fermentation of organic waste. Organic waste such as corn husks, bean sprout skins, banana leaves, vegetable scraps and so on are quite abundant every day. This waste is no less nutritional value. So organic waste can replace the cost of purchasing superior grass.
Organic waste must be cleaned first before use, this treatment aims to ensure that the waste given is free from harmful microorganisms. Market waste in the form of corn husks can be given directly to livestock, while waste from vegetables should be processed first, because it contains a high water content, up to 95%. So if stored without processing, it will rot quickly. Vegetables in the form of cabbage and kale, if given directly to livestock in large quantities without processing, will cause livestock to bloat. If organic waste production is abundant, preservation can be carried out.
Preservation is useful for extending the shelf life. Preservation of organic market waste can be done using several methods, namely by making silas, fertilizer, fish feed. Ingredients such as vegetables and corn husks can be preserved using the silage method, while bean sprouts and corn husks can be preserved by reducing the water content or drying, and can even be made into flour or pellets.
