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
Abstract. Rasyid B, Ala A, Kuswinanti T, Sapareng S. 2020. Exploring functional fungi on organic matter decomposition of oil palm empty bunches as bio-resource in land remediation. Biodiversitas 21: 4247-4252. Organic matter of oil palm by-product has the potential to be applied for land remediation. The objective of this experiment was to explore functional fungi on the decomposition effectivity of oil palm empty bunches. Samples were collected from oil palm plantation fields and oil palm factory. Isolated fungi from decomposed material (trunks and rod) were Penicillium sp., Pleurotus sp., Fusarium sp., Chrysosporium sp., and Aspergillus sp. Fungi in the empty fruit branches were identified as Absidia sp., Tremella sp., and Trichoderma sp., Phytophthora sp., Ulocladium sp., and Chaetomium sp. Within all collected fungal isolates, Pleurotus sp., Trichoderma sp., and Tremella sp. were selected as functional fungi based on the results of the highest lignocellulolytic ability (50-75%). The degradation rate of organic matter of each functional fungi was observed as Trichoderma sp. (24.0%), Tremella sp. (20.0%), and Pleurotus sp. (16.0%). Change of C/N ratio as a result of decomposition showed significant difference compared to control with 22.09 by Trichoderma sp., 24.26 by Pleurotus sp., 26.68 by Tremella sp. and 36.58 in control. This study could be concluded that exploring functional fungi can potentially be applied in the decomposition of oil palm by-product effectively.
Penelitian bertujuan mengetahui interval pemberian pupuk hayati bio nano yang terbaik pada pertumbuhan bibit kelapa sawit di pembibitan awal. Penelitian dilakukan dalam bentuk percobaan lapangan yang menggunakan Rancangan Acak Kelompok yang terdiri atas 5 perlakuan yaitu tanpa pemberian pupuk hayati, pemberian pupuk hayati tiap 1, 2, 3, dan 4 minggu. Masing-masing perlakuan diulang 3 kali dan terdiri atas 3 unit satuan percobaan sehingga terdapat 45 tanaman. Pemberian pupuk hayati bio nano tiap satu minggu memberikan pengaruh terbaik terhadap tinggi tanaman umur 1 – 3 BST, masing-masing 18.05 cm, 26.05 cm dan 35.55 cm, jumlah daun yaitu 4,00, 5,11 dan 7,11 helai, dan diameter batang yaitu 3.88 cm, 7.33 cm dan 11.22 cm, serta bobot yaitu 7,00 gram
