Abstract

Acidic soil is one of the major constraints in the cultivation of horticultural crops, including pakcoy (Brassica rapa L.), as low soil pH can hinder nutrient absorption and root development. This study aimed to evaluate the effect of goat manure enriched with dolomite lime on improving soil chemical properties and enhancing the growth and yield of pakcoy grown in low-pH soil. The research was conducted in Cisantana Village, Cigugur Subdistrict, Kuningan Regency, using a randomized complete block design (RCBD) with a single factor consisting of five treatments and five replications. The treatments included: A (control), B (10 tons/ha of goat manure), C (10 tons/ha of goat manure + dolomite), D (20 tons/ha of goat manure), and E (20 tons/ha of goat manure + dolomite). Observed parameters were plant height, number of leaves, root volume, fresh plant weight, edible weight, relative growth rate, final soil pH, and organic carbon content. Data were analyzed using analysis of variance followed by the Scott–Knott test. The results showed that the application of goat manure combined with dolomite significantly improved soil pH and enhanced the growth and yield of pakcoy. Treatment E produced the best results in most measured parameters. Therefore, the integration of goat manure and dolomite lime is an effective strategy for ameliorating acidic soils and sustainably boosting pakcoy productivity.

Abstract

Kuningan Regency is an area that has abundant natural resource potential, both the wealth of water resources and the potential for agricultural land that is still productive (fertile). Lebakwangi District is one of the areas of Kuningan Regency that has significant agricultural potential. However, the interest of the younger generation in the agricultural sector is still considered low. This study aims to examine the impact of internal factors (motivation and personality) and external factors (family economic conditions and government policies) on the interest of millennial farmers in Lebakwangi District. This research was carried out in Lebakwangi District, Kuningan Regency. The research was carried out from May to June 2025. The method used was a descriptive quantitative approach with a simple random sampling technique for 82 respondents, as well as multiple linear regression analysis using SPSS 27. The results showed that simultaneously these four factors had a significant effect on the interest of young farmers (R² = 0.538). Partially, motivation and personality have a significant influence, while family economic conditions and government policies have no significant effect individually. The results of this study show that strengthening internal factors is the main key in increasing the interest of the younger generation in agriculture. This research is expected to be the basis for formulating a strategy for the development of millennial farmers to maintain the sustainability of the agricultural sector in the region.

Abstract

Tofu wastewater, a by-product of tofu production, can reach volumes up to ten times that of the processed soybeans. This waste contains organic compounds like proteins, carbohydrates, and fats, as well as essential minerals such as nitrogen, phosphorus, and potassium, which benefit plant growth but pose environmental risks if untreated. Fermenting this wastewater with the EM4 bioactivator and coconut water—rich in growth hormones and minerals—produces a nutrient-rich, eco-friendly liquid organic fertilizer (LOF). This fertilizer serves as an alternative to chemical fertilizers often misused by farmers. This study evaluates the use of fermented tofu wastewater and coconut water as LOF for growing land spinach (Ipomoea reptans), chosen for its high consumption and easy cultivation. Results show that applying this fermented mixture significantly affects growth parameters, including stem diameter, fresh weight, number of nodes, leaf area, plant height (at 21 and 28 days), and number of leaves (at 14, 21, and 28 days). The best growth was observed in treatment F6 (40% tofu wastewater fermentation), though it did not exceed the positive control. These findings suggest that fermented tofu wastewater and coconut water enriched with EM4 have potential as sustainable liquid organic fertilizers that promote plant growth while reducing tofu industry waste.
