Biakan yang unggul, media, serta perawatan tanpa adanya kontaminasi menjadi faktor penting untuk mendapat bibit jamur merang yang unggul. Media murni PDA (Potato Dextrose Agar) yang relatif mahal membuat cara kultur jamur merang membutuhkan pilihan media kultur lain. Arang sekam dan sekam padi berpotensi menjadi alternatif media kultur jamur merang karena kandungan karbon yang tinggi. Penelitian ini dilakukan dengan tujuan mendapatkan kombinasi media kultur jamur merang dengan harapan dapat menghasilkan pertumbuhan miselia tertinggi biakan G2 FP007 Faperta Unsika secara in vitro. Penelitian ini dilaksanakan di Laboratorium Pemuliaan dan Bioteknologi Tanaman Fakultas Pertanian Universitas Singaperbangsa Karawang pada bulan Februari sampai dengan bulan April tahun 2023. Metode penelitian yang digunakan adalah metode eksperimen dengan rancangan percobaan Rancangan Acak Lengkap (RAL) Faktor Tunggal dengan 5 kali ulangan. Terdapat 7 perlakuan, yaitu A (PDA 100%), B (Arang Sekam 100%), C (Sekam 100%), D (PDA 80% + Arang Sekam 20%), E (PDA 80% + Sekam 20%), F (PDA 60% + Arang Sekam 20% + Sekam 20%), dan G (Arang Sekam 50% + Sekam 50%). Pengaruh perlakuan dianalisis dengan analisis ragam taraf 5% dan uji lanjut DMRT (Duncan Multiple Range Test) pada taraf 5%. Perlakuan E (PDA 80% + Arang Sekam 20%) menunjukkan hasil rerata pertumbuhan diameter miselia tertinggi setelah perlakuan kontrol PDA 100% yaitu sebesar 6,99 cm. Perlakuan E juga memperlihatkan laju tumbuh miselia tertinggi daripada perlakuan media lainnya dengan pertumbuhan 3,32 cm/hari dikarenakan kandungan yang terdapat pada arang sekam mampu dimanfaatkan secara langsung oleh hifa jamur merang.

Soybean is an important food crop commodity that serves as a source of plant-based protein due to its high nutritional value, safety for consumption, and relatively affordable price compared to other protein sources. In addition to being a food source, soybean also plays an important role in the supply of animal feed and industrial raw materials, making it one of the leading commodities in agricultural development in Indonesia. This study aimed to determine the effect of several types of organic fertilizers on the vegetative growth characteristics of Anjasmoro soybean (Glycine max L. Merril). The experiment was conducted using a Randomized Complete Block Design (RCBD) consisting of six treatments and four replications, including coffee husk compost, green manure, cattle manure, and several combinations of these organic fertilizers. The data were analyzed using analysis of variance (ANOVA) at the 5% significance level, followed by Duncan's Multiple Range Test (DMRT) at the 5% significance level. The results showed that the application of different types of organic fertilizers significantly affected plant height, number of leaves, stem diameter, number of productive branches, leaf area, and fresh root weight. Treatment D produced the best results for plant height (50.17 cm) and number of leaves (14.10 leaves), treatment B resulted in the largest stem diameter (8.50 mm), while treatment F produced the best results for the number of productive branches (6.90 branches), leaf area (146.67 cm²), and fresh root weight (25.82 g).
