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
