Use substance chemistry in a way continously can cause accumulation residue in the soil , which is potential cause effect harm for environment . Therefore that , training intended For improve skills in groups farmer Green Lawu forest in Berjo Village , Karanganyar , in cultivation mold Trichoderma sp. as fungicide natural . Training done through method counseling that includes making starter media using Potato Dextrose Agar (PDA), and multiplication become product powder Ready use with flour media rice and bran . Training results show improvement understanding participant to benefit Trichoderma sp. , good as controller organism the bully plants (OPT) and as booster growth plants . In addition , training This succeed reduce dependence farmers on materials chemistry agriculture that is not friendly environmental and expensive. It is hoped that this program can push adoption Trichoderma sp. in a way sustainable For support system agriculture friendly environment in Berjo Village .

The rice straw waste is a byproduct of rice processing and is a plentiful natural resource in Indonesia. It has been utilized as a renewable energy source to decrease reliance on fossil fuels and tackle worldwide energy concerns. Rice straw waste contains various organic compounds, such as 36.6% cellulose, 25.3% hemicellulose, and 14.3% lignin. These compounds can be converted into various types of bioenergy, such as bioethanol, biogas, biomass, and bioelectricity through fermentation and pyrolysis processes. Rice straw waste has significant potential as a raw material in bioethanol production, biogas and bio-oil. rice straw waste also has the potential to produce bio-oil through the pyrolysis process. Tiny organisms, like bacteria and fungi, have a crucial part in the creation of bioethanol, biogas, and bio-oil. These microscopic organisms will be used in the process of fermentation, decomposition, or other biochemical reactions to convert rice straw waste into the desired renewable energy source. In the production of bioethanol, the use of enzymes such as amylase or cellulase may be required to break down the raw materials into simpler components that can be converted through the fermentation process into bioethanol. The process of producing biogas involves utilizing an anaerobic digester, which is a controlled environment devoid of oxygen. In this environment, microorganisms decompose the organic material found in rice straw waste and generate biogas. The methods used in the production of bioenergy (bioethanol, biogas and bio-oil) from straw waste may vary depending on the context and available technology.
