Abstract

The use of the main growth medium in the form of wood sawdust in mushroom domestication is still higher than that of other organic materials, even though its availability is limited, so efforts need to be made to find a growth medium composition that minimizes the percentage of sawdust use. The purpose of this study was to determine the comparison of treatment 1 (80% teak sawdust, 10% bran, 5% tapioca flour, and 5% agricultural lime) with treatment 2 (70% teak sawdust, 15% bran, 10% tapioca flour, and 5% agricultural lime) on the percentage of growth and mycelium growth of white oyster mushrooms.  Composting of growing media was carried out for 5 days, then baglog making was carried out, after which the baglog was sterilized for 4 hours. After sterilization, the baglog was cooled and inoculated. After inoculation, the baglog is incubated to grow mycelium. Then, after 15 days, data collection and calculation were carried out. The parameters measured were the percentage of growth and mycelium growth of white oyster mushrooms in baglogs. Results showed that the percentage of growth and mycelial growth of white oyster mushrooms in treatment 1 is better than in treatment 2. Reducing the percentage of the main growing medium of teak sawdust and adding the percentage of additional growing media of bran and tapioca flour has a negative impact on the number of baglogs that grow mycelium (percentage of growth) and the growth of white oyster mushroom mycelium. This means that reducing the main media of teak sawdust and adding additional media is not the right growing media composition for domestication of white oyster mushrooms, so it cannot be used as an alternative growing media composition to reduce the use of wood sawdust.

Abstract

Kaliandra (Calliandra calothyrsus Meisn) is a plant capable of producing large amounts of biomass, potentially as a renewable energy source that supports the reduction of dependence on fossil fuels. The transition from fossil fuels to renewable energy is an urgent and long-term solution, as the use of fossil fuels as an energy source contributes to global warming and climate change.This study aims to evaluate the effect of compost fertilizer dosage and compost tea on the growth of height and diameter of kaliandra seedlings. Using a one-factor complete randomized design (CRD) method with treatment of compost fertilizer doses K0 (0 grams), K1 (60 grams), K2 (75 grams) and K3 (90 grams) and compost tea doses TK1 (0 ml), TK1 (50 ml), TK2 (75 ml) and TK3 (100 ml). Research results: 1. The treatment of compost doses and compost tea showed significant differences in the height growth of calliandra seedlings. 2. Compost fertilizer with a dose of 90 grams (K3) showed a better height growth rate than compost tea fertilizer with a dose of 100 ml (TK3), 75 ml (TK2), and 50 ml (TK1). 3. Compost tea fertilizer with doses of 50 ml (TK1) and 75 ml (TK2) showed a better height growth rate than compost fertilizer with doses of 60 grams (K1) and 75 grams (K2). 4. The compost fertilizer dose treatment showed a significant difference in the growth rate of Calandra seedling diameter, while the compost tea dose treatment did not show a significant difference. 5. Compost fertilizer with doses of 75 grams (K2) and 90 grams (K3) showed better diameter growth than compost tea fertilizer with doses of 75 ml (TK2) and 100 ml (TK3). 6.  The optimal dosage recommendation in this study is 90 grams of compost fertilizer and 75 ml of compost tea.
