The present study aimed to examine the effect of locally available agro-industrial wastes on the growth and productivity of pink oyster mushrooms (Pleurotus djamor) and the potential use of substrates as animal feeding based on its compositional change following mushroom growth. A total of three substrate formulations labeled OPF (80% oil palm frond), CS (80% corn straw), and OPFCS (40% oil palm frond + 40% corn straw) were prepared. Aside from the earliest mycelium completion, pinhead formation, and fruiting bodies maturation, CS and OPFCS exhibit the best total yield, dry weight, and biological Efficiency. On the contrary, P. djamor grown in OPF resulted in the minimum in most of the parameters measured. Therefore, CS, single and in combination with OPF could be utilized as an alternative growing media for the cultivation of P. djamor. The analysis of chemical compositions showed that the growth of P. djamor significantly reduced the crude fiber (CF) and increased the crude protein (CP) content of the mycelium-treated substrate. In contrast, THE CP content of the spent is unchanged or relatively lower than that of the initial substrate. It can be concluded that compared to the spent, mycelium-treated substrate had higher values of being used for animal feeding.

This study aims to determine the potential of rations based on local raw materials as a substitute for commercial rations for crude protein, crude fat, and fiber content. This study uses local feed ingredients in Tanah Laut Regency, South Kalimantan Province: local corn, rice bran, palm kernel cake, fish meal, maggot, stone flour, topmix, and commercial rations with the brand AL 100-II Comfeed produced by PT. Japfa Comfeed Indonesia Tbk. This research method is an experimental method using a completely randomized design (CRD), with five ration treatments and four replications. The treatment rations were A (100% Commercial / Control Ration), B (75% Commercial Ration + 25% Local Ration), C (50% Commercial Ration + 50% Local Ration), D (25 % Commercial Ration + 75% Local Ration) and E (100% Local Basal Ration). The parameters measured were crude protein (%), crude fat (%), and crude fiber (%). The results showed that the nutritional quality of local and factory rations at specific compositions had no significant effect (P>0.05) on crude protein, crude fat, and fiber content. This study concluded that the composition of the mixture of local and commercial rations did not affect the nutritional content, especially crude protein, crude fat, and crude fiber. Crude protein content ranges from 16.87% to 17.96%, crude fat from 5.17% to 6.29%, and crude fiber from 5.17% to 6.29%.

Penelitian ini bertujuan untuk mengetahui potensi ransum berbasis bahan baku lokal sebagai pengganti ransum komersil terhadap kadar air dan abu. Penelitian ini menggunakan bahan pakan lokal yang ada di Kabupaten Tanah Laut, Provinsi Kalimantan Selatan yang terdiri dari jagung lokal, dedak padi, bungkil inti sawit, tepung ikan, maggot, tepung batu, topmix dan juga ransum komersil. Metode penelitian ini adalah metode eksperimen menggunakan Rancangan Acak Lengkap (RAL), dengan 5 perlakuan ransum dan 4 ulangan.  Ransum perlakuan yaitu A (100 % Ransum Komersil / Kontrol), B (75 % Ransum komersil + 25 % Ransum Lokal) C (50 % Ransum Komersil + 50 % Ransum Lokal), D (25 % Ransum Komersil + 75 % Ransum Lokal) dan E (100 % Ransum Basal Lokal).  Parameter yang diukur adalah kadar air (%) dan kadar abu (%).  Hasil penelitian menunjukan bahwa kualitas nutrisi ransum lokal dan ransum pabrikan pada komposisi tertentu  memberikan pengaruh berbeda tidak nyata terhadap kadar air dan kadar abu. Dari hasil penelitian ini disimpulkan bahwa komposisi campuran ransum lokal dan ransum komersil tidak berpengaruh terhadap kandungan nutrisi terutama kadar air dan kadar abu. Kadar air berkisar 11,64% -12,38% dan kadar abu berkisar 16,14% - 16,76%.
