Abstract

This reserch aims to determine the effect of comparison of planting media and and growth regulator concentration on the growth and propagation of G-0 Potato seeds. This research was carried out in the Screen house of the Raya Village garden, Berastagi District, Karo Regency, North Sumatra Province, with a place of ± 1,300 m asl. This research was carried out from January to April 2019. This reserch used the Factorial Randomized Block Design method of two treatment factors, namely the comparison treatment of planting media with the symbol "M" which consists of five levels, namely: without compost (M0 ), 30% compost (M1), 50% compost (M2), 70% compost (M3), and 100% compost (M4). The second factor was giving a growth regulator concentration with the symbol "Z" which consists of three levels, namely: without concentration (Z0), 1.5 ml /L (Z1), and 3 ml / L (Z2). So that 15 treatment combinations were obtained, each treatment was repeated 3 times. The results of the observational data were then analyzed for variance with an F level of 5%. If there is a significant difference (p <0.05), then the test is continued with the Duncan test. The results showed that the treatment comparison of the planting media had a significant effect (p <0.05) on the variable growth in plant height, development of stem diameter, production each sample, and production each plot, and had no significant effect (p> 0.05) on number of branch. The treatment of growth regulator concentration had a significant effect (p <0.05) on production variables each sample, and production each plot, and had no significant effect (p> 0.05) on variable growth in plant height, development of stem diameter, and number of branch.

Abstract

Red beans (Phaseolus vulgaris L.) or jogo beans are in great demand by the public, because of their good nutritional value and can be made in various dishes. Low-cost agriculture can be carried out through an environmentally friendly agricultural system by utilizing local natural materials around the location such as kipait, rabbit manure, fish fertilizer, vegetable and fruit waste without reducing the quality and quantity of vegetables. This study aims to determine the increase in growth and yield of kidney beans (Phaseolus Vulgaris L) through the application of Liquid Organic Fertilizer (LOF) based on local resources. This research was conducted in the IP2TP Berastagi garden, Karo Regency, with an altitude of ± 1340 meters above sea level, andisol soil types. This research was carried out from May to September 2020. The design used in this study was a Randomized Block Design (RBD) with 3 replications and 10 treatments, namely: A=Without LOF (Control), B=Kotciplus LOF, 10 ml / l water, C=LOF Kotciplus, 20 ml / l water, D=LOF Kotciplus, 30 ml / l water, E=LOF Kipait, 10 ml / l water, F=LOF Kipait, 20 ml / l water, G=LOFKipait , 30 ml / l water, H=LOF Market Waste, 10 ml / l water, I=LOF Market Waste, 20 ml / l water, J=LOF Market Waste, 30 ml / l water. The results showed that the application of several types and concentrations of POC on kidney beans did not have a significant effect on growth or yield. However, there was a tendency that in general the plants treated with POC showed a higher yield compared to the yields of plants that were not given POC. Likewise, for each type of POC the higher the concentration the higher the yield.

Abstract

Indonesia is an agricultural country where most of the farmers grow fruits andvegetables. Each harvest of harvests will leave a part that is considered to have noeconomic value anymore. This part is known as waste. Agricultural waste can be in theform of fruit peels, fruit flesh (which is taken by seeds), leaves, stems and so on. Alongwith technological advancements, starting with the utilization of waste with the properapplication of technology, will be able to raise the value of waste. The abundance ofbanana production in Indonesia shows that, throughout the year there will be abundantavailable banana waste, in the form of banana peels, banana flowers (heart), or bananastem stumps. Banana peel pectin is one of the products produced by banana peels thatare not yet known in the Indonesian community. Pectin can be extracted from the residueof fruit processing, such as orange peel, the rest of the making of apple juice, coconutfiber, banana peel, brown skin and others. The content of pectin in various fruits variesgreatly. In fruits of different varieties the pectin content will differ. The banana peelwaste which is around 62-67% of the total weight, can be used as a source of pectin. Ifthe skin of a banana is used as a source of producing pectin, it will be one of the wasteutilization businesses, as well as an effort to develop industries, especially smallindustries in the supply of pectin, which is currently still expensive with such a large use.Solving or extracting pectin from fruits is affected by cooking and pH of the solution.Research Methods: The design model used in this study is factorial randomized completedesign (RAL), which consists of two main factors, namely: Factor I: Immersion Length inChlorine Solution (P) consisting of 4 levels: P1 (1 min), P2 (3 min), P3 (5 min), P4 (7min). Factor II: Citric Acid Concentration (K) consisting of 4 levels: K1 (1.5%), K2(2.0%), K3 (2.5%), K4 (3.0%). The study used 2 replications. The results of the studygenerally indicate that the effect of immersion time in chlorine solution and theconcentration of citric acid on the quality of the liquid pectin of kepok banana influencesthe observed parameters. The best crude pectin content is 2.039% (7 min) and 2.604%(3.0%). The best methoxyl content is 3.930% (7 min) and 5.210% (3.0%). The best jellygrade is 299,254 (7 min) and 299,445 (3.0%). The best thickness is 1.036 (7 min) and1.045 (3.0%).
