Abstract
Universitas Diponegoro mempunyai TPST yang banyak menampung sampah organik daun. Pengomposan yang sudah dilakukan belum mampu mengolah seluruh sampah karena jumlah tenaga kerja terbatas dan proses ini membutuhkan perlakuan khusus seperti penyiraman, pembalikan, penyaringan, dan pemisahan kompos dari belatung. Vermikomposting merupakan alternatif yang dapat diterapkan karena mudah, tidak berbau, dapat menurunkan ukuran bahan baku kompos, serta dapat menghasilkan unsur hara mikro seperti Fe, Mn, dan Zn yang bermanfaat bagi pertumbuhan dan perkembangan tanaman. Penelitian diawali dengan mengomposkan sampah daun kering selama 12 hari dengan penambahan MOL daun mahoni dan memantau kondisi fisiknya setiap hari sebelum kompos digunakan sebagai pakan cacing dalam metode vermikomposting yang dilakukan selama14 hari. Penelitian ini menunjukkan kandungan unsur hara mikro Fe, Mn, Zn vermikompos mengalami peningkatan dilihat dari data hasil uji laboratorium dan perbandingan nilai hasil vermikomposting dengan pakan cacing. Unsur Fe meningkat sebesar 39,39%, Mn meningkat 30,42%, dan Zn meningkat 46,34%. Kandungan unsur hara mikro vermikompos rata-rata yaitu unsur Fe sebesar 38,47 mg/l, Mn 3,261 mg/l, dan Zn 0,9322 mg/l, nilai ini masih cukup kecil jika dibandingkan dengan batas masksimum unsur hara mikro pada pupuk yang diizinkan menurut peraturan (SNI 19 70-30 2004) tentang Standar Kualitas Kompos. Berdasarkan reduksi sampahnya cacing Lumbricus rubellus hanya mampu mereduksi sampah daun sebesar 6,91% berat tubuhnya dalam sehari. Kata Kunci: kompos, sampah daun, vermikomposting TPST of Diponegoro University has a lot accommodating leaf organic waste. Composting has not been able to process the entire waste because the amount of labor is limited and this process requires special treatment such as watering, reversing, filtering, and separation of compost from maggots. Vermicomposting is a workable alternative because it’s easy, odorless, can reduce the size of raw materials, and can produce micro nutrients such as Fe, Mn, and Zn that are beneficial to the growth and development of plants. The study begins by composting dry leaf litter for 12 days with the addition of MOL mahogany leaves and monitor the physical condition every day before the compost is used as a worm feed in the method of vermicomposting performed for 14 days. This study showed that the content of micro nutrients Fe, Mn, Zn vermicompos increased based the laboratory test results and the comparison of vermicomposting results with worm feed. Fe element increased by 39.39%, Mn increased by 30.42%, and Zn increased 46.34%. The content of micronutrients of vermicompost averaged 38.47 mg/l, Mn 3,261 mg/l, and Zn 0.9322 mg/l, this value is quite small when compared with the minimum limit of micro nutrients in the fertilizer permitted by regulation (SNI 19 70-30 2004) about Standar Kualitas Kompos. Based on the reduction of garbage Lumbricus rubellus worm is only able to reduce leaf waste 6.91% of body weight in a day. Keywords: compost, leaf litter, vermicomposting
