Use of Edible and Medicinal Oyster Mushroom [Pleurotus ostreatus (Jacq.: Fr.) Kumm.] Spent Compost in Remediation of Chemically Polluted Soils

This paper aims to assess the technical, economic, and financial viability of cultivation of mushroom from coffee waste and pulp. The raw material characteristics and technical aspects were analyzed. In techno economic analysis, the investment is defined, and the financing of the project were explained. It is believed that production of mushroom from coffee waste and pulp is feasible as well as profitable in San Salvador. Use of coffee waste in the production of mushroom will prevent its damping in landfills and thus be friendly to environment as well.

Penambahan nutrisi perlu dilakukan untuk meningkatkan produktivitas pertumbuhan jamur tiram putih (Pleurotus ostreatus). Salah satu bahan yang dapat digunakan adalah serbuk jagung. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan serbuk jagung pada komposisi media tanam terhadap pertumbuhan miselium bibit F1 jamur tiram putih (Pleurotus ostreatus) dan mengetahui konsentrasi serbuk jagung yang paling baik digunakan pada pertumbuhan miselium bibit F1 jamur tiram putih (Pleurotus ostreatus). Penelitian ini mengunakan Rancangan Acak Lengkap (RAL) 4 perlakuan dan 3 ulangan sehingga diperoleh 12 satuan percobaan; P0 (perlakuan kontrol), P1 (25%), P2 (50%), dan P3 (100%). Variabel yang diukur adalah persentase pertumbuhan miselium yang diamati pada hari ke-6, 12 dan 18 dan waktu penyebaran miselium Hari Setelah Inokulasi (HSI). Data hasil penelitian dianalisis menggunakan analysis of variance (ANOVA) dengan uji lanjut menggunakan uji Beda Nyata Terkecil (BNT). Hasil penelitian menunjukkan bahwa ada pengaruh pada pertumbuhan miselium bibit F1 jamur tiram putih (Pleurotus ostreatus) dengan penambahan serbuk jagung pada komposisi media tanam. Selain Itu, konsentrasi serbuk jagung yang memberikan hasil yang paling baik terhadap pertumbuhan miselium adalah P2 dengan konsentrasi 50%. Kata kunci : miselium F1; Pleurotus ostreatus; serbuk jagung ABSTRACTAdditional nutrition needs to be done to increase the productivity of oyster mushroom (Pleurotus ostreatus) growth. One of the materials that can be used is corn powder. This study aimed to determine the effect of corn powder on the planting medium composition towards mycelium growth of oyster mushroom F1 seeds (Pleurotus ostreatus) and to find the best concentration of corn powder to grow mycelium seeds F1 oyster mushroom (Pleurotus ostreatus). This research was an experimental study using a Completely Randomized Design (CRD) with 4 treatments namely; P0 (control treatment), P1 (25%), P2 (50%), and P3 (100%), and 3 repetitions so that obtained 12 experimental units. The variables measured were the mycelium growth percentage on days 6, 12, and 18, and the mycelium widespread time after the day of inoculation. The data were analyzed using ANOVA then continued on the Least Significant Difference (LSD) test. The results showed that the addition of corn powder on oyster mushroom growing media affected mycelium growth of the oyster mushroom F1 seeds (Pleurotus ostreatus). It also found that the P2 with a 50% concentration of corn powder gave the widest mycelium growth. Keywords: corn powder; mycelium; Pleurotus ostreatus
