Pemanfaatan MOL Limbah Sayur pada Proses Pembuatan Kompos

Abstract

Tujuan penelitian ini adalah mengetahui fluktuasi harian faktor-faktor lingkungan pada proses pengomposan menggunakan mikorganisme lokal (MOL) limbah sayur dan EM4, mengetahui kualitas fisik kompos menurut penilaian responden dan kualitas kimia kompos berdasarkan analisis laboratorium. Penelitian dilaksanakan selama 4 minggu, terdiri dari dua perlakuan, yakni pengomposan menggunakan bioaktivator MOL limbah sayur dan EM4. Data yang diambil meliputi fluktuasi harian faktor-faktor lingkungan selama proses pengomposan, kualitas fisik (warna, bau dan tekstur) dan kualitas kimia (kadar air, pH, C/N rasio P₂O₅, dan K₂O) setelah kompos matang. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa fluktuasi harian faktor lingkungan kompos dengan MOL limbah sayur dan EM4 memberikan gambaran fluktuasi yang cenderung sama. Kualitas fisik kompos menurut penilaian responden masing-masing menunjukkan skor 30 pada aspek warna, bau dan tekstur. Penelitian ini menyimpulkan bahwa  kualitas fisik kedua perlakuan kompos memiliki kategori warna kehitaman, bau seperti tanah, dan bertekstur halus sesuai kriteria SNI Nomor SNI 19-7030-2004. Namun demikian C/N rasio kompos yang menggunakan limbah sayur lebih baik karena telah memenuhi kriteria yang ditetapkan SNI dibanding kompos dengan menggunakan EM4.

The purpose of this research are to know the daily environmental factor fluctuation in the composting process using vegetable waste local microorganism (MOL) and EM4, the compost’s physical quality based on respondent’s evaluation and compost’s chemical quality based on laboratory analysis. This research was conducted for 4 weeks, consisted of two treatments, which were composting using vegetable waste MOL bioactivator and EM4 bioactivator. The data taken including the daily environmental factor fluctatuion during the process, physical quality (colour, smell and texture), and chemical quality (water level, pH, C/N ratio, P₂O₅ and K₂O) after the compost was processed. The data were analysed descriptively. The result of the research showed that the compost’s daily environmental factor fluctuation with vegetable waste MOL and EM4 showed a relatively similar result.  Each compost’s physical quality based on respondent’s evaluation give a result with score 30 in aspect of colour, smell and texture. This research conclude that the physical quality of both treatment showed blackish colour, smell like soil and smooth texture according to SNI 19-7030-2004 criteria. However, the C/N ratio of compost using vegetable waste was better than the EM4 compost, because it’s already meet the criteria determined by SNI.
