Abstract

The mustard plant is one of the horticultural commodities that is popular with the public because it has high fiber and nutritional content so it has high economic selling value. Various cultivation techniques that can be done to increase mustard greens production are by applying liquid organic fertilizer which can increase plant growth and production. Liquid organic fertilizer is an organic fertilizer designed as a balanced food complete with macro and micro nutrients for various types of plants. This research aims to determine the effect of mustard greens growth and production on the provision of liquid organic fertilizer. This research used a non-factorial randomized block design (RAK) with 5 treatment levels. The first factor is the use of liquid organic fertilizer (P0: 0 cc/l; P1: 2 cc/l; P2: 4 cc/l; P3: 6 cc/l; P4: 8 cc/l).The results showed that liquid organic fertilizer had a significant effect on leaf area but had no significant effect on plant height. The most efficient concentration of liquid organic fertilizer for the growth and production of mustard greens is 6 cc/liter. Keywords : mustard greens, liquid organic fertilizer, growth

Abstract

Eggplant production in Indonesia remains relatively low and has not been able to meet market demands. Long-term use of inorganic fertilizers has led to declining organic matter content in soil, soil degradation, and environmental pollution. To address these issues, agricultural waste such as rice husk can be converted into charcoal or biochar to improve soil quality degraded by excessive use of chemical fertilizers. In addition to biochar as organic material, other organic inputs like liquid organic fertilizer can potentially improve soil physical properties. This research aims to determine the effect of giving rice husk biochar and the correct dose, to find out the effect of applying liquid organic fertilizer and the right concentration and to find out the interaction between giving rice husk biochar and liquid organic fertilizer on eggplant growth and production.The study employs a Randomized Block Design (RBD) factorial with 2 treatment factors. The first factor involves rice husk biochar application at 4 levels (A0: control, A1: 0.6 tons/ha or approximately 30 g/plant, A2: 1.2 tons/ha or approximately 60 g/plant, and A3: 1.8 tons/ha or approximately 90 g/plant). The second factor is liquid organic fertilizer application at 4 levels (B0: control, B1: 0.1 mg/l, B2: 0.3 mg/l, and B3: 0.5 mg/l). The results of the study indicate that rice husk biochar application can increase plant height and leaf number, the best dose for rice husk biochar is 90 g/plant.Application of liquid organic fertilizer has not been able to affect plant height and number of eggplant leaves. Keywords : eggplant, rice husk biochar, liquid organic fertilizer

Abstract

Former tin mining land (known locally as camoy or kulong) has the potential to be utilized as fish cultivation land. Kulong possesses potential for fish farming due to its age, which supports the availability of trophic minerals essential for fish life. Fish farmers frequently encounter problems with disease outbreaks and mortality caused by pathogens, leading to low production yields. Improving the quality of the cultivation environment, including reducing sedimentation from commercial feed, is one solution to mitigate fish diseases and mortality. This community service aims to provide training on environmentally friendly feed for fish farmers through training and mentoring in its application. The program successfully enhanced the partners' ability to produce cost-effective (organic) environmentally friendly feed from agricultural waste (oil palm kernel meal, dregs, bran), which demonstrably improved the quality of the cultivation environment, reduced fish diseases and mortality, and has the potential to increase the quality and quantity of fish production.
