Even though the Covid-19 pandemic has hampered activities, there are still many opportunities to carry out activities that are beneficial to the community. Of course, these activities are carried out in accordance with the protocol for preventing the spread of Covid-19, one of which is the Real Work Lecture (KKN) of the State University of Malang (UM) which this year was held online. UM students, who this year conducted KKN in Madiredo Village, Pujon District, Malang Regency, initiated several work programs, one of which is processing waste into aerobic compost (24/6).

The work program is based on the village's efforts to process waste into useful products, but processing is constrained by time. “Madiredo Village has had an Integrated Waste Disposal Site (TPST) since 2017. Until now, various efforts have been made so that waste can be processed into useful products. The plastic waste is sold, less the organic waste is processed into fertilizer. The problem is that the processing is still constrained because it takes a lot of time, it can take months, even up to a year, while the garbage from residents keeps coming. If you wait too long, the accumulation of garbage will increase, so that the TPS area will become narrower, "said Mahfud, Head of Madiredo Village.

Some students who did KKN conducted a compost-making trial using kitchen waste, such as vegetable waste. “We have tested compost in our respective homes using kitchen waste, such as vegetable scraps. First, we prepared two buckets, kitchen waste, soil, EM4, sugar and water. Well then perforate a bucket, cut into small pieces the kitchen waste, then put the soil into the bucket. Continue to enter the waste, then give EM4 liquid, maltose, and water to the container. For waste and the soil is made in layers. After that, the container is closed and wait one week for it to be stirred again, ”explained Devi Choirunisya, the person in charge of the work program.

The UM KKN students then prepare a small drum or drum that is used to facilitate the process of decomposing the waste, the decomposition uses the help of decomposing bacteria found in EM4 liquid fertilizer. On that same day, taking into account the protocol for preventing the spread of Covid-19, KKN UM students visited Madiredo Village to hand over the booths. sico or a disinfectant booth as well as making aerobic compost at the TPST. However, because it was already late in the afternoon and the TPST workers would return from the TPST, they only milled the waste waste. Meanwhile, the composting process was continued on another day. As a follow-up, Devi Choirunisya stated that the KKN UM group working in Madiredo Village would provide modules and counseling on making compost using compost bin media to TPST workers. The village and TPST workers are very happy with the contribution of UM students in processing waste waste. In the future, this contribution is expected to be of benefit to Madiredo Village.
