ABSTRAK Analisis kandungan gizi jamur merang (Volvariella volvacea) telah dilakukan, dengan tujuan untuk mengetahui kandungan gizi jamur merang (Volvariella volvacea) yang dibudidayakan pada media tanam janjang kelapa sawit dan jerami padi. Hasil analisis gizi jamur merang dengan menggunakan media janjang kelapa sawit dan jerami padi yaitu, kadar air 89,52 dan 88,29%; kadar abu total 0,86 dan 0,92%; kadar lipid 0,58 dan 0,53%; kadar protein 3,16 dan 3,12%; serta kadar karbohidrat 5,88 dan 7,14%. Hasil analisis data menunjukkan jamur merang yang dibudidayakan pada media tanam janjang sawit memiliki kadar air, kadar lipid dan kadar protein yang lebih tinggi, sementara jamur merang yang dibudidayakan pada media jerami padi menunjukkan kadar abu total dan kadar karbohidrat yang lebih tinggi. Kandungan gizi dalam jamur merang dipengaruhi oleh komposisi media tanam dan nutrisi tambahan pertumbuhan jamur merang berupa dedak dan sagu. Kata kunci : jamur merang, janjang kelapa sawit, jerami padi, gizi ABSTRACT The analysis study was conducted to identify the nutritional content of straw mushroom (Volvariellavolvacea) cultivated by using the oil palm bunch and straw planting mediums. The result of straw mushroom nutrient analysis by using the mediums showed that the straw mushroom nutrient consisted of 89.52% and 88.29% water, 0.86% and 0.92% pure dust, 0.58% and 0.53% lipid, 3.16% and 3.12% protein, as well as 5.88% and 7.14% carbohydrate content. The data analysis result showed that straw mushroom which was cultivated on planting medium of oil palm bunch has morewater, lipid, and protein content than the straw mushroom cultivated on straw medium. Meanwhile, the straw mushroom which was cultivated on straw medium has more dust and carbohydrate contentthan the mushroom using oil palm bunch planting medium in cultivating. The nutritional value in the mushroom was influenced by the composition of planting medium and additional nutrients such as bran and sago. Keywords: straw mushroom, oil palm bunch, straw, nutrient
