Penilaian Kualitas Kompos Jerami Padi Dan Peranan Biodekomposer Dalam Pengomposan

Abstract

Pemberian kompos pada tanah dapat memperbaiki sifat fisik tanah seperti pembentukan agregat atau granulasi tanah serta meningkatkan permiabilitas dan porositas tanah. Karena itu, peningkatan produktivitas padi perlu dipacu dengan penambahan bahan organik seperti kompos jerami. Penelitian menggunakan 9 kotak kompos dengan menggunakan bahan jerami padi. Jerami padi diambil dari daerah Tampalla Kecamatan Bone-bone Kabupaten Luwu Utara, Indonesia. Penelitian dilakukan dalam bentuk eksperimen dengan Rancangan Acak Kelompok, tiga kali ulangan dan tiga perlakuan. Perlakuan biodekomposer (B), terdiri dari Tanpa Biodekomposer (B0), Promi (B1) dan EM-4 (B3). Pengambilan contoh kompos pada akhir percobaan ketika kompos dianggap telah matang untuk analisis sifat kimia serta kandungan senyawa organik. Pemberian biodekomposer promi dan EM4 pada proses pengomposan limbah jerami padi dapat meningkatkan laju pengomposan. Hal ini dapat dilihat dari parameter penurunan suhu (proses pematangan) yang lebih cepat dibanding kontrol, rasio C/N yang memiliki nilai lebih rendah dibanding kontrol, dan kadar unsur hara lebih tinggi dibanding kontrol

The Long Composting Period Effect of Leaf Shallots on the Compost Quality

“…The decomposition process of green shallots into compost was easier than the decomposition process of other organic materials, such as straw, bagasse, and livestock manure. Rice straw has a C/N ratio of 48.15; this value must be reduced through the composting process [7]. The results of the analysis showed that the composting time affected the quality of the produced compost.…”

“…The composting process aims to reduce the C/N ratio of organic matter in the compost. Compost with a C/N ratio value > 20 is not recommended being used for agricultural land because of the immobilization of N elements; moreover, if the C/N ratio reaches 12-20, the nutrients bound to the humus will be released through the mineralization process so that they can be used by plants [7]. The composting period affects the C-organic content and the C/N ratio of the compost.…”

Rural Community Empowerment through the Utilization of Straw as Compost

“…This result is in line with [4], [5], [6], who reported that the personal characteristic component is an important indicator in increasing empowerment. In addition, empowerment can also be determined by factors from outside the characteristics, such as a person's involvement in a program or activity [3], also determined by external factors such as; availability of infrastructure, extension activities, farmer group functions, and access to information [7], [8] [9] [10]. Meanwhile, Permana and Effendy [11] explained that the empowerment of women farmer groups is significantly influenced by external factors consisting of; support for group members, the availability of facilities and infrastructure, policy support, and outreach activities.…”

Utilization of Rice Straw Waste in the Manufacture of Edible Film (Study of the Addition of Lignin and Sorbitol)

“…Data BPS menyebutkan produksi gabah padi pada tahun 2016 hingga 2020 untuk daerah Kabupaten Sidbpoarjo berturut-turut sebesar 218.900 ton, 204.425 ton, 239.183 ton, 234.788 ton, dan 225.346 ton dengan rerata didapat sebesar 224.528 ton (BPS, 2021). Rasio antara bobot gabah padi yang dipanen dengan jerami pada saat panen umumnya 2:3, sehingga didapat rata-rata jerami padi yaitu sebesar 336.792 ton (Idawati et al, 2017). Umumnya jerami padi dimanfaatkan sebagai pakan ternak sebesar 31%, 7% untuk keperluan industri dan sisanya akan dibakar dipersawahan (Ambarsari et al, 2019).…”
