Abstract

Compost can be defined as the result of the decomposition of organic matter, while composting is a process in which organic matter is decomposed biologically, especially by microbes that utilize organic matter as an energy source. The effect of adding hydrogel to compost is a soil conditioner that focuses on water and nutrient retention so that it can reduce the use of irrigation water and increase the ability of plants to grow. The application of hydrogel and compost can improve physical properties such as bulk density, porosity, number of pores, water content of field capacity, water content of harvesting wilting point, available water, chemical properties, and soil biology. This study aims to determine the composition of the addition of hydrogel to tablet compost made from bio-slurry which is most appropriate for the moisture content and hardness of tablet compost. The method used in this research is experimental with direct testing in the laboratory. The results of the study The higher the addition of hydrogel, the higher the water content because there is still bound water trapped in the hydrogel and the best tablet compost or the highest water content was obtained in the P5 treatment, which was 18.35%, and the addition of hydrogel caused the tablet compost to become soft and elastic. so hardness is easier to destroy. The results of the analysis show that the best tablet compost hardness value is found at P0 of 97.0000 Newton

Abstract

This study aims to determine the working mechanism of the vertical type mangosteen peel penepung machine, to determine the production capacity of the results of the performance analysis of the vertical type mangosteen peel penepung machine, to determine the electrical power requirements and to determine the efficiency of the machine the results of the performance analysis of the vertical type mangosteen peel penepung machine. The method used in this research is the Experimental method by conducting experiments in the Agricultural Workshop Lab. The design used is a Completely Randomised Design consisting of 3 treatments using a vertical type mangosteen peel penepung machine with load variations, namely, P1 = 50 grams, P2 = 100 grams, P3 = 150 grams using a 1400 rpm rotation. Each treatment was repeated 3 times so as to get 9 experimental units. The research data were analysed using load variations (Anova table) at the 5% level and if there was a treatment that had a significant effect, further tests were carried out using the Real Differential Test (BNJ) at the 5% real level. The results of the analysis and research show that the working mechanism of the machine uses an electric motor as a driving force, the highest mangosteen skin pressing capacity in P3 is 177.80 grams / second and the lowest in P1 80.82 grams / second, the use of the highest electrical power requirements in P3 0.17 watts and the lowest electrical power usage P1 is 0.09 watts and the efficiency of the machine in P1, P2 and P3 is the same at 53.33%.
