Abstract

Pulping is one of the stages of coffee processing. There are various types of coffee pulpers owned by several farmers, but they are not mobile because they have a large construction, and there are several farmers who still use manual coffee peeling machines driven by human labor sources. The purpose of this research is to make a 3-dimensional design of a mobile type wet coffee pulper. The method is carried out starting from determining the capacity of the machine, analyzing the design, determining the dimensions, sketching each part of the machine, determining the material to form a complete design that is ready to be simulated. The results obtained in this study are a 3-dimensional design of a mobile pulper machine, which shows that the peeling machine is mounted on a modified motorcycle frame and uses the rotating power from the tip of the magnetic shaft of the motorcycle engine flywheel. The filling capacity of the hopper is 18 kg. The transmission system used is pulley and belt and transmits power from the engine to the pulper unit with an additional reduction shaft. The engine speed of 1200 rpm is reduced to 390 rpm so that the peeling cylinder has a speed of 110 rpm. The results of this research are expected to provide a reference for the physical fabrication of mobile pulper machine prototypes.

Abstract

Rice is a major commodity as a source of carbohydrates for the Indonesian people. Efforts to increase rice production have been made by the government, but these have not been matched by optimal harvesting and post-harvest handling, resulting in high yield losses of nearly 10%. Data from the Central Statistics Agency (2024) shows that rice harvest losses reach 9.5% during harvesting and 4.8% during the post-harvest stage, which has the potential to reduce national grain production, currently recorded at around 65 million tonnes of grain. The Tompobulu sub-district, Bantaeng Regency, has around 1,000 hectares of rice fields at an altitude of ±500 metres above sea level with small plots and a terraced pattern. The main problems faced by organic rice farmers in this area are low knowledge of cultivation, organic fertiliser production, and good post-harvest handling. These conditions cause high yield losses, both quantitatively and qualitatively, which do not provide economic incentives for farmers to increase their income. Paddy with high moisture content is also easily damaged and increases yield losses. Appropriate and location-specific post-harvest handling is needed to reduce yield losses and improve grain quality. In areas with narrow land ownership and hilly topography, appropriate technology in the form of power threshers is a suitable solution, as modern harvesting equipment such as combine harvesters cannot operate effectively in terraced rice fields.
