Abstract

OPEFB has low biodegradability so its utilization is very limited. Oyster mushrooms are mushrooms that are capable of producing enzymes capable of degrading cellulose, hemicellulose, and lignin contained in) OPEFB. The research objective was to determine the effect of the composition of the growing media on the production of oyster mushrooms and changes in the composition of the resulting baglog waste. The study was carried out with the combination treatment of rubber wood and OPEFB, with levels: (a) 100% rubber wood powder and 0% OPEFB, (b) 75% rubber wood powder and 25% OPEFB, (c) 50% rubber wood powder and OPEFB 50%, (d) 25% rubber wood powder and 75% OPEFB, (e) 0% rubber wood powder and 100% OPEFB. Observation of raw material composition, mycelia growth, wet weight of the fungus, biological efficiency, changes in lignin content, cellulose, and hemicellulose before and after being used as a growing medium for oyster mushrooms. The results showed that the fastest mycelial growth occurred in the use of 100% OPEFB media. The highest oyster mushroom production occurred in the media 100% rubber sawdust. The higher the wet weight of the oyster mushrooms produced, the less the weight of the baglog waste produced. The oyster mushroom fermentation process for 60 days was able to reduce the content of 3.39% cellulose, 11.01% hemicellulose, and 1.98% lignin. Keywords: OPEFB, Oyster Mushroom, Cellulose, Hemicellulose, Lignin

Abstract

Penelitian ini bertujuan menganalisis tingkat penerapan biosecurity serta produktivitas dan mortalitas ayam petelur di PT. Sumber Protein Unggul Lampung Tengah. Penelitian dilaksanakan pada Juni–Agustus 2026 di peternakan ayam petelur PT. Sumber Protein Unggul, Desa Rama Oetama, Kecamatan Seputih Raman, Kabupaten Lampung Tengah. Metode penelitian menggunakan deskriptif kuantitatif dengan pengumpulan data melalui observasi, wawancara, diskusi, pencatatan (recording), dan studi pustaka. Responden wawancara berjumlah 10 orang yang terdiri atas satu manajer, satu supervisor, dan delapan anak kandang. Penerapan biosecurity dinilai berdasarkan tiga aspek, yaitu konseptual, struktural, dan operasional. Produktivitas diukur menggunakan Hen Day Production (HDP), sedangkan kesehatan populasi dievaluasi melalui mortalitas. Hasil penelitian menunjukkan bahwa penerapan biosecurity konseptual memperoleh persentase 83,33%, struktural 77,77%, dan operasional 91,66%, yang seluruhnya dikategorikan sangat baik berdasarkan kriteria penelitian. Rata-rata HDP ayam petelur umur 56–59 minggu sebesar 98,02%, sedangkan mortalitas rata-rata sebesar 0,01%. Hasil tersebut menunjukkan bahwa penerapan biosecurity yang dilaksanakan di perusahaan berjalan baik dan sejalan dengan produktivitas telur yang tinggi serta mortalitas yang rendah.
