Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh ampas tebu dan alang-alang (Imperata cylindrica) sebagai media pertumbuhan jamur tiram putih (Pleurotus ostreatus) terhadap kandungan nutrisinya. Ampas tebu dan alang-alang dipilih sebagai media pertumbuhan alternatif, karena tidak hanya mengandung lignoseluosa, tapi juga tersedia berlimpah di lingkungan. Variasi komposisi ampas tebu:alang-alang yang digunakan adalah 75:25 (A1); 50:50 (A2); 25:75 (A3); 0:100 (A4); dan 100:0 (A5). Pada penelitian ini, kandungan nutrisi yang dianalisis adalah kadar air, abu, protein kasar, lemak kasar, dan total karbohidrat. Metode yang digunakan adalah termo-gravimetri, furnis, Kjeldahl, dan ekstraksi Soxhlet. Hasil yang didapatkan yaitu kadar air dan lemak kasar terendah sebesar 77,29% dan 0,09% pada variasi A4, sedangkan kadar abu dan protein kasar tertinggi didapatkan sebesar 1,16% dan 11,70% pada variasi A3 dan A2. Sementara kadar karbohidrat terendah didapatkan pada variasi A5 sebesar 2,23%. Variasi media A4, dengan komposisi 100% alang-alang, lebih disukai untuk menghasilkan jamur tiram dengan kandungan nutrisi yang paling baik ============================================================================== The purpose of this research was to investigate the effect of bagasse and cogon grass (Imperata cylindrica) mixtures as the growth medium of edible white oyster mushroom (Pleurotus ostreatus) on its nutritional substances. Bagasse and cogon grass became the alternative substrates for growth medium, which are not only contain lignocelluloses substance but also abundantly available in the environment. The used compositions of bagasse:cogon grass were 75:25 (A1); 50:50 (A2); 25:75 (A3); 0:100 (A4); and 100:0 (A5). In this study, nutritional substances were determined on its proximate analysis (moisture, ash, crude protein, crude fat, and total carbohydrate contents). The used methods were thermo-gravimetric, furnace, semi-micro Kjeldahl, and Soxhlet extraction. The lowest moisture content and crude fat were obtained 77.29% and 0.09% on A4 variation, respectively, while the highest ash and protein contents were obtained 1.16% and 11.70% on A3 and A2 variations, respectively. Furthermore, the lowest carbohydrate content was obtained 2.23% on A5 variation. It indicated that A4 variation medium, which contains 100% cogon grass substrate, was preferred for producing the white oyster mushroom with the best nutrition contents
