Abstract

The existing peanut shell crusher machine can help peanut farmers in the process of breaking the peanut shell, but there are still a few obstacles in the process of breaking, namely the opening of the full opening stopper. This causes the peanut peeling machine to not operate optimally. The action to be taken is to modify the size of the B-type pulley and v-belt. Testing of the breaker machine that has been designed, uses peanuts with a moisture content of 5.60%. The test results show that for the 1/2 opening stopper, the yield produced is 68.8% in 45 seconds; 3/4 aperture, yield of 68.6% in 32 seconds of processing; and for full opening, the resulting yield is 71% in 20 seconds of processing time and obtain an effective tool performance capacity of 90 Kg/Hour.

Abstract

The purpose of this study was to evaluate the land suitability of peanuts and corn in Gurinda Jaya Village, Jagebob District, Merauke Regency. The research was carried out from July 2020 to August 2020. The research location was carried out in Gurinda Jaya Village, Jagebob District, Merauke Regency. The materials used in this research are: Gurinda Jaya Village Map, 10 year rainfall data (2011-2020), humidity data, temperature data, morphological data of Gurinda Jaya village, soil samples. The suitability parameters for Peanut and Corn include temperature, dry month, rainfall, soil drainage, texture, CEC, wet saturation, pH, C-Organic, salinity, total alkalinity-N, P2O5, K2O, land suitability class consists of class S1 (very suitable), S2 (moderately suitable), S3 (marginally suitable), N1 (not suitable). The results showed that peanut plants in paddy fields/moorlands, scrub lands and dry land forests obtained marginal land suitability class (S3) with limiting factors for nutrient retention (f) and available nutrients (n) for paddy fields/fields and dryland forests. , while the limiting factors in bushland are rooting media (r), nutrient retention (f), and available nutrients (n). Land suitability class for maize, on marginally suitable paddy fields/moor (S3) with limiting factors for nutrient retention (f), available nutrients (n), for bushland and dry land forests are not suitable at this time (N1) with limiting factors available nutrients (n). Basically, the existing limiting factors can be improved by fertilizing and liming.

Abstract

The aim of the research is to produce a pig feed cutting machine with an electric motor drive. This study used an experimental method by making and testing pig feed cutting tools with one type of blade using an electric motor drive. The materials used in testing the tool were water spinaches, sweet potato leaves, and banana stems. The calculations performed are the effective capacity of the tool and the efficiency of the tool. Tests were carried out on 3 types of feed ingredients, each of which was repeated 3 times with an electric motor rotation of 1400 rpm. The results showed that the pig feed cutting machine with an electric motor had the specifications: overall height 110 cm, front width 45 cm, side width 50 cm side inlet funnel height 17 cm and width 10 cm, funnel bottom exit height 23 cm and width 17 cm, the width of the electric motor mount is 45 cm and the length is 28 cm. The cutting blade uses a grass cutter blade with a blade length of 305 mm and a blade thickness of 1.6 mm. The effective capacity of the tool for cutting water spinaches (162 kg/hour), sweet potato leaves (162 kg/hour), banana stem (163.8 kg/hour). The efficiency of the tool for cutting kale and sweet potato leaves was the same, namely 90%, while the efficiency of the tool for cutting banana stems was 91.1%.

Abstract

The people of Kampung Tambat, Tanah Miring District, Merauke Regency rely on the flow of the Maro River as a water source for processing sago stems into sago starch and also for daily living activities. Even though the water is cloudy, it is still used by the community. This research aims to produce a filter tool based on activated carbon from coconut shell charcoal, silica sand, and gravel to improve the physical quality of Maro River water which is used by the community in processing sago starch. This research uses an experimental method by designing a filter and to determine the performance of the filter, testing equipment and analyzing the physical parameters of water in the laboratory. Research stages: (1) preparation stage, including designing filter equipment, providing tools and materials; (2) the stage of making water purification equipment and installing filter media, namely coconut shell activated carbon, silica sand, gravel, sponge, dacron; (3) filter performance testing stage; (4) test stage for raw water samples and water after filtering in the laboratory which includes parameters, temperature, total dissolve solid (TDS), turbidity, color, odor and pH. The results of laboratory tests on raw water samples show that the physical parameter values of the water meet the Environmental Health Quality Standards for Water Media for Hygiene Purposes (Permenkes No. 2 of 2023), namely temperature, TDS, taste, odor and pH. The test results of Maro River water samples after processing using filters based on activated carbon from coconut shells, silica sand and gravel show that several parameters have experienced a significant decrease even though they are not yet in accordance with the established standards. The test parameters that experienced a decrease were turbidity and color.
