Abstract

Long beans are classified as seasonal plants that can begin to be harvested approximately 6-9 weeks after planting and then periodically until approximately 3 months after planting, then the plants experience aging which results in low flower and fruit production. The harvest can be in the form of young pods which contain lots of vitamins A, B and C; medium for the production of mature seeds containing protein, fat and carbohydrates. The productivity achieved by farmers is still much lower when compared to the potential yield of long beans which can reach 20-25 tons/ha of fresh pods. The purpose of the study was to determine the increase in the productivity of long bean plants through the application of organic vermicompost fertilizer.  The results of the study provide the following conclusions: There was a significant effect on the treatment of vermicompost on all observed variables, namely plant length, number of leaves, number of fruit (pods) per plant, and fresh weight of fruit (pods) per plant; and giving vermicompost as much as 1.50 kg per plant (treatment K6) gave a better average effect than other treatments at the end of the observation on the variables of plant length, number of leaves, and number of fruit (pods) per plant, although it was not significantly different by giving vermicompost as much as 1.25 kg per plant and 1 kg per plant on the variable total fresh weight of fruit (pods) per plant studied.

Abstract

A popular boba is the “brown sugar” boba which is dark brown. Boba can be made with different color variations, one of which is red dragon fruit skin because it contains anthocyanins that can be used as natural dyes. It also contains high enough antioxidants, so it is good for health. Unfortunately, it has a less favorable aroma and taste, so adding other mixtures such as cinnamon with a distinctive taste and aroma is necessary. This study aims to determine the panelists' preference for cinnamon boba with the addition of red dragon fruit peel extract. Descriptive research with an experimental approach to produce products with different compositions and organoleptic tests to determine the panelists' preference for products has been used in this study. The mixed formulas of red dragon fruit peel extract with water used were P0 (red dragon fruit peel extract 0 g, 250 ml water), followed by P1 (50 g, 200 ml), P2 (100 g, 150 ml), P3 (150 g, 100 ml) and P4 (200 g, 50 ml). Then, the preference test was carried out on 30 panelists related to color, aroma, taste, and texture with the rating categories of strongly dislike (1), dislike (2), quite like (3), like (4), and very like (5). The results showed that the higher the red dragon fruit peel extract content, the more favorable the color produced; The level of preference for aroma and taste was relatively the same in all treatments, and the P3 treatment produced the most preferred texture.

Abstract

This study aimed to determine the potential residues of the rice crop from the second planting period, which were fed with a mixture of pistia compost and rice straw of various compositions with the Brassica rapa L. pakcoy. The study used a factorial randomized block design, the first factor was 7 levels divided into 5 compost mixtures and 2 comparison treatments (NPK fertilizer treatment and control) as follows; control, M1 : 100% pistia, M2 : 75% pistia + 25% rice straw, M3 : 50% pistia + 50% rice straw, M4 : 25% pistia + 75% rice straw, M5 : 100% rice straw and M6 : NPK ., and the second factor is the presence or absence of addition of compost in the second rice planting period divided into 2 levels; 1. (+) = addition of compost, 2.(-) = no addition of compost. The results showed that the residue of composting for the second planting period of rice had a positive effect on soil fertility, especially in the repeated addition of compost, which showed a very significant positive priming effect. The highest positive priming effect was shown by the medium of high-quality compost, namely the treatment of 100% pistia (M1+) seen in the growth parameters and yield of Brassica rapa L pakcoy. The increase in growth due to the addition of repeated compost was 5.10% to 14.24%, and an increase in yield was 5.41% to 11.11% in various treatments of mixed compost media. The treatment with repeated addition of compost gave a significant response to the P uptake of Brassica rapa L plants but the treatment without compost (-) showed 36.72% higher than the treatment with the addition of compost (+).
