The number of rabbits in Batu City according to the Agriculture Service data, from 2011 to 2014 decreased from 32,833 to 28,035. This is because rabbit sales tend to fluctuate, depending on market demand so that the income earned by farmers is uncertain. AKUR Rabbit Animal Group is one of the active rabbit farms. This group has 300-450 rabbits that can produce 50-70 kg of solid waste every day and 15 liters of urine. However, abundant rabbit solid waste is still not utilized properly, some are composted conventionally and most are directly disposed to vacant land near settlements. This causes pollution of the surrounding environment.
Departing from these problems, 5 UB’s Faculty of Agricultural Technology (FTP) students: Rachmad Wijaya, Achmad Ilmi Arya Putra, Lucky Wiratama, Vera Cahya Rinjayani, Riyadlotul Ula, under the guidance of Lecturer Dr. Ir Gunomo Djoyowasito, Ms. creating alternative technology to treat livestock waste with the help of an ACTOR (Aerobic Bioreactor) tool that uses pH, temperature and humidity parameters.
ACTOR is a tool that makes it easy for farmers to process rabbit manure into compost because there are automation systems based on Fuzzy Logic System and an IoT-based Chamber which is connected to the Blynk Application so that the quality is easily monitored and maintained. Another advantage, which is very low energy use and compost processing time, is up to 3x faster than conventional treatment.
