Abstract

Background: Oil palm empty fruit bunches (OPEFB) represent the largest form of solid waste generated from palm oil production, comprising approximately 23 % of the weight of every ton of fresh fruit bunches (FFB) processed. Untreated OPEFB waste causing pollution problems and increase toxicity due to methane emission. This study aims to evaluate the potential of OPEFB as a growth substrate for the cultivation of Pleurotus ostreatus and Volvariella volvacea, as well as to assess the reduction in lignocellulosic content following fungal biodegradation. Methodology: The experiment was conducted using solid-state fermentation (SSF), and lignocellulose content was analyzed using the Chesson method and SNI 0429:2008 through descriptive quantitative analysis. Findings: Over a 21-day incubation period, mycelial growth of both fungi successfully colonized the OPEFB baglogs, resulting in a 1–2 % reduction in baglog weight. Both P. ostreatus and V. volvacea demonstrated the ability to degrade lignocellulose by secreting lignin peroxidase (LiP), manganese peroxidase (MnP), laccase, cellulase, and hemicellulase enzymes. Initial lignocellulose levels of OPEFB were 18 % lignin, 57 % cellulose, and 20 % hemicellulose. After 21 days of incubation, P. ostreatus reduced these levels to 10 %  lignin, 47 % cellulose, and 19 % hemicellulose, while V. volvacea reduced them to 11 % lignin, 52 % cellulose, and 18 % hemicellulose. Contribution: These findings indicate that OPEFB is a viable substrate for mushroom cultivation and can be effectively biodegraded by these fungi, offering a sustainable approach to managing palm oil industry waste. The treated OPEFB can be used as organic fertilizer, animal feed, and briquettes

Abstract

Gerakan literasi sekolah merupakan upaya untuk meningkatkan budaya literasi di sekolah. Penelitian ini bertujuan untuk menganalisis implementasi gerakan literasi sekolah di SD Negeri 2 Margodadi. Pendekatan kualitatif digunakan dalam penelitian dengan menggunakan metode studi kasus. Teknik pengumpulan data melalui observasi, wawancara dan studi dokumentasi. Hasil penelitian menunjukkan bahwa implementasi gerakan literasi sekolah melalui pojok baca di SD Negeri 2 Margodadi telah berjalan maksimal, namun terdapat beberapa kendala dalam proses implementasinya. Beberapa kendala yang ditemukan seperti kurangnya koleksi buku anak di perpustakaan, kurangnya waktu khusus untuk kegiatan literasi di luar jam belajar, serta peran guru yang kurang maksimal dalam memfasilitasi dan terbatasnya waktu karena pembelajaran tatap muka. terbatas dan siswa kurang antusias membaca serta berkunjung ke perpustakaan masih kurang. Upaya mengatasi kendala dalam pelaksanaan Gerakan Literasi Sekolah antara lain menerapkan strategi membaca, pemberian penghargaan, pemberian motivasi dan pemberian fasilitas kepada siswa. Meski demikian, program ini secara bertahap berhasil meningkatkan minat membaca siswa. Rekomendasinya antara lain memperkaya anak koleksi buku, peningkatan kompetensi guru, dan keterlibatan orang tua dan masyarakat yang lebih aktif.
