Pemanfaatan Limbah Sampah Kota Sebagai Kompos

Abstract

Penelitian ini didasarkan pada upaya pemanfaatan limbah sampah kota yang keberadaannya melimpah dan mencemari lingkungan agar dapat dimanfaatkan menjadi suatu produk yang memiliki nilai ekonomis tinggi yaitu kompos, selain itu juga dapat menjadi solusi dalam mengatasi masalah kelangkaan serta mahalnya harga pupuk saat ini. Penelitian ini dilaksanakan di kampus Politeknik Pertanian Negeri Samarinda, dengan lamanya waktu penelitian adalah 3 bulan terhitung mulai bulan Juli sampai dengan Oktober 2020 yang meliputi: persiapan alat dan bahan, pembuatan kompos, pengambilan data dan analisis kompos. Tujuan penelitian yaitu mengetahui lama waktu pembuatan kompos hingga kompos dikatakan jadi, dan mengetahui kualitas kompos berdasarkan standar SNI 19-7030-2004. Hasil penelitian menunjukkan bahwa; kompos jadi pada hari ke-19 yang ditandai dengan warna kompos coklat kehitaman, tidak berbau, bentuk/tekstur remah dan suhunya sudah stabil mendekati suhu ruang dan kompos yang dihasilkan jika dibandingkan dengan standar SNI 19-7030-2004 untuk C organik, N dan K memenuhi standar sedangkan pH H2O, C/N rasio dan P belum memenuhi standar SNI 19-7030-2004.

Bacteria Pseudomonas taiwanensis as a decomposing agent of peat fiber

“…While in the variation of the addition of 15%, 20%, and 25% of Pseudomonas taiwanensis bacteria in the 7-day curing period, there was a tendency to decrease the crude fiber content and decrease the medium fiber content which was less when compared to the variation of the addition of Pseudomonas taiwanensis bacteria by 10% and 5% in the 7-day curing period. This occurs because the variation of the addition of 5% and 10% of Pseudomonas taiwanensis bacteria in the 7-day curing period contributes less water to the sample so that the aeration process takes place earlier than in samples with variations of the addition of 15%, 20%, and 25% of Pseudomonas taiwanensis bacteria in the 7-day curing period (Ngapiyatun et al, 2020). This is different from the results of research (Prativi et al, 2018), where the crude fiber content increased.…”

“…In addition, all samples added with Pseudomonas taiwanensis bacteria released a strong foul odor during the 7 and 14 days of curing. This indicates that the aeration process is inhibited during the decomposition process, producing foul-smelling compounds such as organic acids, ammonia, and H2S (Ngapiyatun et al, 2020). The aeration process or oxygen exchange process in peat samples is inhibited because the samples have anaerobic conditions due to increased water content (Prativi et al, 2018).…”

“…However, nutrient content of compost varied [8].SNI number 19-7030-2004 is Indonesian standard of domestic compost. It should contain at least 0.4% Nitrogen, 0.1% P2O5, 0.2% K2O, and C/N ratio in the range of 10-20 [9]. Commercial organic fertilizers based on Ministry of Agriculture decree number 261/KPTS/SR.310/M/4/2019 should contain at least 2% of Nitrogen+P2O5+K2O and C/N ratio 25 [10].…”
