Abstract

This research aimed to determine the effect of Trichoderma sp dosage and cow manure dosage on the growth and yield of cayenne pepper. The research used a randomized block design with three replications. The factors studied were the dose of Trichoderma with three levels, namely T0 (Trichoderma dose of 0 g / polybag), T1 (Trichoderma 0.5 g / polybag), and T2 (Trichoderma 1 g / polybag), as well as the dosage factor of cow manure with four levels are P0 (cow manure dose 0 g / polybag) P1 (cow manure 125 g / polybag), P2 (cow manure 250 g / polybag) and P3 (cow manure 375 g / polybag). The variables studied were plant height, stem base diameter, number of leaves, number, number of fruits, the weight of fruit crops, and production of tonnes/ha. The results showed that the treatment dose of Trichoderma T0 (without Trichoderma), T1 (Trichoderma dose of 0.5 g / polybag), and T2 (Trichoderma 1 g / polybag) had no significant effect on all plant parameters, while the dose treatment of cow manure in treatment P0 (without cow manure) significantly different from treatment P1 (cow manure 125 g / polybag), P2 (cow manure 250 g / polybag), and P3 (cow manure 375 g / polybag). There was no interaction between doses of Trichoderma with the dose of cow manure on the growth and yield of cayenne pepper

Abstract

This study aimed to determine the response of lettuce plants to type planting media and watering intervals in the verticulture system. This research method used a split-plot design with eight treatments and three replications, including Main plots P1 (2 days watering interval) and P2 (4 days watering interval). The second treatment as sub-plots consisted of planting media: M1 (soil: manure), M2 (manure: sand), M3 (manure: husk charcoal), and M4 (soil: manure: husk charcoal). Observations included growth parameters (plant height, number of leaves, leaf area) and harvest parameters (total fresh weight of plants, fresh weight of roots, total dry weight of plants, dry weight of plants without roots, dry weight of roots). The result of the 2nd watering interval was able to significantly increase the growth component and fragrant lettuce plants compared to the 4th watering interval. Different types of planting media showed a significant effect on plant height but did not affect the number of leaves, leaf area, and components of the yield of fragrant lettuce.

Abstract

The general problem of organic vegetable farming is the cultivation technique which must have organic principles, both in the use of inputs and cultivation techniques. In addition, the market for organic products is still limited. This study aimed to formulate the best strategy for the Vigur Organic Women's Farmer Group. The research location was determined used purposively and the sample was taken by accidental sampling. The data was analyzed by using a qualitative descriptive method using the SWOT analysis method. The results showed that the Vigur Organic Women Farmer Group was in cell IV of the IE matrix, which means that they were carrying out a growth and development strategy, while the results of the SWOT analysis were in quadrant I (growth) with a value of 2.45 in the internal position, namely strength. The priority of the alternative strategy to be developed based on the results of the QSPM (Quantitative Strategic Planning Matric) analysis is to optimize and increase the volume of organic vegetable production with the highest total attractive value (TAS) of 6.44. The priority of the next alternative strategy is to maintain organic certification of 6.12, and the last alternative strategy carried out by the Vigur Organic Women's Farmer Group is to manage and increase cooperation with distributors with a TAS value of 6.00

Abstract

Coconut milk hydrolyzed using lipase enzymes (endogenous) produces free fatty acids (lauric acid, capric acid, and myristic acid) and monoglycerides that are useful as anti-bacterial and anti-viral. Hydrolysis for 72 hours at 40 oC produced 25.86% lauric acid and 14% monoglycerides from the total oil. Soybean sprouts contain protein, vitamin E, vitamin B, vitamin C, antioxidants, anthocyanins, and isoflavones which are very good for health. Soybean sprouts contain lipase enzymes. If coconut milk mixed with soybean sprout extract is then incubated, the hydrolysis process will be faster so that the amount of free fatty acids produced is higher. This study aimed to study the proportion of coconut milk with soybean sprout extract and incubation time on the quality of health drinks from coconut milk and soybean sprouts. The study used two factors arranged in a factorial manner. The first factor is the ratio of coconut milk with soybean sprout extract 100%: 0%: 75%: 25% and 50: 50%. The second factor is the incubation time (hydrolysis) which is 24, 38, and 72 hours at 40 oC. The results showed that the ratio of coconut milk with soybean sprout extract had no significant effect on levels of free fatty acids, N-amino, taste, color, and aroma. While the incubation time significantly affects free fatty acids, N-amino, taste, and smell. Health drinks from coconut milk and soybean sprout extract with a ratio of 75%: 25% incubation time (hydrolysis) 48 hours is the best treatment with a free fatty acid content of 0.74% N-amino 0.158%, taste score of 4.3 (like), color 3,9 (like) and scent 4 (like).
