The sweet potato (Ipomoea batatara L.) is one of the world’s important tubers with a production of more than 133 million ton. In 2019, the Laboratory of Agricultural Equipment and Machinery designed a Prototype I Washer The machine is not optimal, reaching 67.13%, and it needs to be modified because the skin of the sweet potato is cleaned and exfoliated so that it can reduce the quality of the sweet potato. The method used in this research is engineering, which is a non-routine design activity with new construction of process and product. Base on Matlab program, the result of the modification research and performance tests, is by using the prototipe I washer, the percentage of the level of cleanliness was 80.02%. Where with an increase 67.13% using the performance machine. Based on the evaluation of technical feasibility and engine performance tests, it is found that the propulsion power needs 1 HP and the deflection of the frame is only 13.06 mm. The theoretical capacity of the engine is 231.68 kg.hour-1, the actual capacity is 100 kg.hour-1 with an efficiency of 44.39%, the noise level of 77 dB and the engine vibration of 13.43 m.s-1.

“…It was due to the limited human resources and low production facilities [6]. Several studies regarding cleaning machines such as potato cleaning machines, cassava cleaning machines and taro cleaning machines have been carried out, but there is no specific sweet potato cleaning [7]. For this reason, it is necessary to conduct a research regarding the technology of Cilembu sweet potato cleaning machine technology.…”

Sweet potato is a food local product that it is very popular in domestic and foreign consumers. This is because the unique sweetness taste when consumed directly by the consumers. Cilembu Village, in Sumedang is a center of sweet potato production which has been exported to Malaysia, Japan, Korea and Singapore with a production capacity of 10 ton.ha-1 . Unfortunateyl, sweet potatoes cleaning process is still low, with about 50 kg.day-1 - 70 kg.day-1 because of it’s manually and conventional processed. In order to increase the cleaning capacity, it was neccesary to do the the research of sweet potato cleaning machine technology . The aim of this study was to design a prototype of sweet potato cleaning machine with a capacity of 100 kg.hr-1 . The method conducted in this research was engineering design with observation of research, characteristics with sweet potato, design criteria, functional and structural design, figure design, technical analysis, mechanism process, functional machine and performance test. The measurement results of sweet potato showed that the bulk density, angle of repose, roundness are 562.52 kg.m -3 , 70.500 , 0.1. The clening machine prototype was produced with dimension of 400 mm (length) x 490 mm (height) x 400 mm (width) with a power source generator using 1 HP electric motor. The resulted of sweet potato cleaning machine functional test showed that actual capacity was 103 kg.hr-1 . In general, the results of engine performance testing can be concluded that the machine can function properly, which can clean sweet potatoes from soil dirt

“…The tools and machines referred to include shredding machines that process organic waste into compost or biomass briquettes. Shredding is meant to increase the surface area of organic materials, thereby accelerating the decomposition process with the help of decomposing bacteria [5]. Based on research results [6], the significant influence of the effective microorganism four bioactivator was observed in expediting the decomposition process of organic materials into Compost.…”

The global issue of organic waste poses a serious threat to the environment and public health. With the increasing production of organic waste driven by population growth and urbanization, waste management systems worldwide are confronted with inevitable pressures. The decomposition process of organic waste generates methane gas, contributing not only to global climate change through the greenhouse gas effect but also posing risks of air and water pollution. The primary function of organic waste lies in its ability to become a valuable resource through recycling and composting processes. The potential use of organic waste as a source of renewable energy through biogas or biomass production also presents promising prospects. The objective of this research is to design a reel-type chopper machine for more optimal waste processing. The research method employed is engineering, involving non-routine design activities to create something new in both process and form. The results of the study show that the designed reel-type organic waste shredder has dimensions of 800 mm in length, 750 mm in width, and 1042 mm in height. The machine consists of four main components: the frame hopper, shredding cylinder, and discharge hole. The chopper machine has a power of 2.2 kW, a chopper capacity of 1 ton/hour, and a cutting length of 2–5 cm. The advantages of the shredded output from this reel-type chopper machine can accelerate the decomposition and fermentation processes of organic waste. The smaller and uniformly shredded particles provide a larger surface area for the activities of decomposing microorganisms. Additionally, reel-type machines are more efficient in processing materials with high moisture levels, such as wet branches or leaves. By ensuring optimal particle size, reel-type machines also enhance the efficiency of composting, as well as the production of compost briquettes and briquettes fueled by organic waste. Therefore, the role of reel-type organic waste shredder machines is crucial in maximizing the value of organic waste, accelerating the recycling cycle, and effectively reducing environmental impact.
