This study aims to increase the productivity of baby corn plants in latosol soil by administering eggshell flour and chicken manure. Latosol soil that dominates Indonesia has high acidity levels and low organic matter content, so it requires effective soil improvers. The experiment used a factorial randomized block plan. Soil analysis showed an increase in pH after treatment. Although statistical analysis did not show a significant difference, the observation results showed that the T3A2 combination gave the best results in plant height and cob length. These results are relevant as initial information for the development of environmentally friendly organic waste-based soil improvers, especially to increase productivity on marginal land. The practical implication is that the use of this organic material can be an economical alternative for farmers to reduce dependence on chemical fertilizers.

Optimization of White Oyster Mushroom (Pleurotus ostreatus) Growth Using Various Media Enriched with Millet Flour

This study aims to evaluate the best growing medium for the mycelium growth of F1 oyster mushroom (Pleurotus ostreatus) seeds using millet flour as a nutritional supplement. A Completely Randomized Design (CRD) was applied with two factors: the type of growing medium (corn, sawdust, rice husks) and the concentration of millet flour (0%, 25%, 50%, 75%). Observed variables included mycelium growth (cm), mycelium density, and daily growth on the 7th, 14th, and 21st days after inoculation. The results indicated that corn without millet flour (J1P0) produced the best mycelium growth, while adding 25% millet flour to corn (J1P1) and sawdust (J2P1) enhanced mycelium density. However, higher millet concentrations (50% and 75%) tended to reduce growth efficiency due to excessive moisture content. This study recommends using millet flour at low concentrations to improve the efficiency of sustainable F1 oyster mushroom seed production.

This study evaluates the effect of Artemia enrichment with garlic (Allium sativum) on the growth and survival of vannamei shrimp (Litopenaeus vannamei) post-larvae. Using a completely randomized design (CRD), four garlic enrichment doses were tested: 0 ppm (control), 250 ppm, 500 ppm, and 750 ppm, with three replicates each. Results showed no significant effect on larval growth, with the highest length recorded at 11.5 mm. However, survival increased significantly, reaching 88.28% at 750 ppm. Allicin in garlic likely acts as a natural immunostimulant, enhancing larval resistance to stress and infection. The optimal dose for Artemia enrichment is 750 ppm. This study highlights garlic’s potential as a natural ingredient to improve vannamei shrimp hatchery practices.
