Abstract

Desa Ujung-ujung, Kecamatan Pabelan, Kabupaten Semarang merupakan desa yang sebagian besar penduduknya mengandalkan perekonomian dari sektor pertanian. Namun pada pelaksanaan pertaniannya, desa ini belum memanfaatkan hasil alam, dalam hal ini kotoran sapi, sebagai bahan dasar pupuk organik yang dipergunakan dalam pertaniannya sendiri maupun diperjualbelikan. Sehingga proposal pengabdian masyarakat ini bertujuan agar masyarakat Desa Ujung-ujung dapat membuat kompos berbahan kotoran sapi guna meningkatkan pertanian maupun perekonomian masyarakat. Metode pengabdian masyarakat yang dilakukan dengan tiga tahapan; tahap persiapan, tahap sosialisasi dan aplikasi, serta tahap akhir. Tahap persiapan dilakukan dengan pembuatan modul pengomposan. Tahap sosialisasi dilakukan dalam rapat warga dan sosialisasi khusus, serta pelatihan pembuatan kompos dari fermentasi kotoran sapi. Tahap akhir adalah pembuatan laporan akhir. Pada kegiatan pengabdian kepada masyarakat ini,  masyarakat Desa Ujung-ujung telah mampu membuat pupuk kompos padat berbahan dasar kotoran sapi yang dapat digunakan dalam pertanian, namun untuk proses mengkomersilkan produk membutuhkan pendampingan lebih lanjut.

Abstract

Waste water treatment of paper industry yield side product in the form of sludge which have generated problembecause there is no continuation processing. Composting sludge which come from waste water processing differfrom other composting organic solid waste, which generally in the form of dry substance. In this research usedadditional substance in the form of organic domestic solid waste, with variation sludge : domestic solid waste(kg/kg) successively 1 : 1, 1 : 4, 1 7, 3 : 2, and 5 : 3. Composting method is done by open windrow, where thecompost heaped longly and let to be opened (aerob). Result of research indicate that to the overall of variationof compost really have fulfilled standard of good ripeness compost according to SNI 19-7030-2003 and alsoaccording to other ripe compost standard. Besides, all variation of compost have yielded ripe compost withcharacteristic fulfilling hara required by crop. Variation Compost 1 : 1 representing the best compost with COrganiccontent 41,507 %, N-Total content 3,008 %, ratio C/N 13,80, moisture rate 44,03 %, P-Total content1,085 %, K-Total content 4,183 %, final temperature 30,3° C and pH 7,98

Abstract

Energy consumption for power generation in Indonesia is highly dependent on fossil energy, which is mostly supplied from coal-fired power plants. Indonesia has the potential of biomass natural resources that are rich in Carbon Neutral fuels and can be an alternative to stone replacement fuels such as palm kernel shell biomass and pelet efb. Biomass effectiveness tests were conducted at PLTU Tembilahan Riau, with test variables of 25% palm kernel shell biomass co-firing and 5% EFB pelet biomass co-firing with a maximum operational load of 7 MW for 6-8 hours. The results of data analysis are done descriptively. The tested palm kernel shell biomass has a calorific value of 4190 kCal/kg and the calorific value of EFB pelets is 4084 kCal/kg. While the coal used in PLTU Tembilahan has a calorific value of 4199 kcal/kg. The emission results produced in the 5% EFB pelet biomass co-firing test process for sulfur dioxide (SO2) was 97.24 mg/Nm3 and Nitrogen Oxide (NOx) was 497.47 mg/Nm3. While the NOx value of co-firing 25% palm kernel shell biomass is 378.2 mg/Nm3 The emission value is still far below the required standard and below the average emission with 100% coal. The electricity production cost of co-firing 25% palm kernel shell biomass and 5% pelet biomass is more economical than the electricity production cost of 100% coal.
