Waste is a source of problems, if not managed properly it will cause environmental pollution, especially in residential settlements that live around landfills in Puuwatu District. The purpose of this community service activity is to reduce the pile of waste in the Puuwatu sub-district landfill through the application of the principle of zero waste, namely by processing organic solid waste into compost, leachate into a decomposer microorganism solution, and recycling inorganic waste for verticulture media. Activities undertaken to achieve the objectives of the Community Partnership Program (PKM) are through mass and group counseling to partners, training and plot demonstrations. Through these activities, partners who live around the landfill had been able to process organic solid waste, with the hope that the volume at the landfill will decrease, and the partner's income will increase. Partners who were actively involved in the activity had been able to produce compost (labeled Komsa-Mitra) that was ready to be commercialized, and are also able to process leachate as a source of decomposer microorganisms (labeled mollin) in the composting process. Partners around the Puuwatu landfill were also able to utilize waste plastic and rubber containers into a vegetable cultivation container with a verticulture system in the yard and the hervested vegetable was used to meet the family's nutritional needs.

Organic solid waste will undergo a decomposition process and produces some gases compounds such as a large enough of Methane (CH4), Carbon Dioxide (CO2) with Oxygen (O2) and N2. The high heating value of CH4 in biogas can make biogas as a good source of renewable energy and environmentally friendly. Biogas calorie efficiency is proportional to the concentration of CH4 in biogas. However, the quantity and quality of biogas that produced in landfill depend on the characteristic and density of domestic solid waste in landfill. The composition of organic and inorganic waste and the density of waste pile will alter the CH4 content. This study focuses on measuring CH4 content of the solid waste with different density while also identifying the composition of disposed solid waste. The result indicates that the CH4 content ranges from 33% to 57.7% with 22.19% to 42.24% of CO2 and approximately 1.21% - 7.92% of O2. The presence of inorganic waste and density level of waste contribute to the decomposition rate and CH4 content.

Solid waste which is sent to Jatibarang landfill in Semarang City can reach up to 4000 m3/day. The composition of solid waste consists of 61.95% of organic waste and 38.05% of inorganic waste. The environmental impacts of solid waste can be reduced using bioreactor methods which being able to accelerate the solid waste decomposition. Large amount of solid waste which is sent to Jatibarang landfill certainly has great potential to environment pollution. Therefore, a technology such as landfill bioreactor is needed to speed up the decomposition process of organic solid waste. Landfill bioreactors are characterized using a range of technologies in order to create an suitable environment for degradation processes. In this study four bioreactors simulated landfills that consist of hybrid bioreactors and anaerobic control bioreactors. The result shows that hybrid bioreactor has increases the decomposition process of organic solid waste. The hybrid bioreactor also produce more methane in subsequent anaerobes.

In the present investigation, the weight, growth, adaptability and production of humus of a calf foot of Californian red worm (Eisenia foetida) fed with compost (made from animal excreta and organic waste) and organic remains were evaluated. The evaluation was carried out in Tarma, Junín Region. A breeding ground was built with 3.2 m3 cement bricks (6.10 m long  1.05 m wide and 0.50 m high); with a 5 cm thick screed with a 2” PVC drain pipe with a west-east slope, raised by the west side at 15°. A population of 10,000 individuals (10 kilograms) was sown, a sample of 370 individuals was extracted by applying a Simple Random Sampling (MAS) whose average weight and length was 0.3 g and 30 mm. they were fed for 3 months (90 days), the calf was divided into 21 sampling points from which 383 worms were weighed and measured whose average weight and length were 0.38 g and 33.24 mm (3.32 cm). Data were taken every day at 2:00 pm, hydrogen potential (pH) and humidity (soil peach meter), substrate temperature (digital thermometer), ambient temperature (thermohygrometer) were recorded. The average weight of the worms varied from 0.30-0.38 g, the average length varied from 30-33.24 mm. The presence of tiny heels and worms demonstrated their adaptability. The production of humus was 3 tons, the efficiency of the breeding stock was 93.75%. The final substrate had an average of 6.72 pH, 13.61°C temperature, 69.86% humidity and 19.5°C ambient temperature. Consequently, vermicompost is an alternative in the treatment of organic solid waste to be developed in high Andean areas.
