Abstract

The reuse of coconut shell waste into briquettes is a way to reduce waste in the community and can be one of the livelihoods, because it utilizes coconut shell waste into briquettes which can be done simply, and comes from coconut shell waste that is easily found in the community. Coconut shell waste that is scattered in the community if left unchecked can become a problem, such as: becoming a source of disease and becoming a nest for mosquitoes. This implementation method is carried out in two major stages, namely the design and manufacture of a briquette printing machine from coconut shell waste. The result achieved in this activity is the creation of a briquette printing machine from coconut shell waste with the resulting pellet size of 5 cm x 5 cm x 5 cm. Based on the results and discussion described above, it can be concluded that the working system of the coconut shell briquette printing machine works well and as desired. The suggestion for the development of the next briquette printing machine is to focus on a cutting system that functions as a briquette dough pusher to the required size. This is, with the aim of making it easier for MSMEs and the community in making briquettes from coconut shell waste and being able to increase the productivity of cattle.

Abstract

The Bangka Belitung region is a province in Indonesia with abundant water resources. However, the water quality in this area often does not meet health standards, prompting residents to seek alternative sources of clean and hygienic drinking water. One chosen solution is refillable drinking water depots. One such depot is Alam Water, located in Air Ruai, Pemali District, Bangka Regency, Bangka Belitung Islands. However, the process of transferring gallons from the filling station to the distribution truck is still done manually by workers, leading to suboptimal productivity. This study aims to design and create a gallon transfer tool capable of transporting two 18.92-liter gallons. The research method follows the VDI 2222 methodology, which includes planning, concept, design, and completion stages. The result of this method is the development of a gallon transfer tool capable of transporting two 18.92-liter gallons, tested by transferring gallons from the filling station to the distribution truck 25 times, with a total time of 365.02 seconds or approximately 6.083 minutes.

Abstract

The manufacturing industry in Indonesia has experienced significant growth. This increase has also impacted the demand for motorcycle spare parts. Currently, brake pads are composed of asbestos, which makes them prone to overheating and failure when reaching high friction temperatures. Therefore, an alternative brake pad material is an organic material mixed with coconut shell powder and bamboo fiber. This study aims to analyze the wear and hardness levels of motorcycle brake pads made from coconut shell powder and bamboo fiber. The study used varying ratios of coconut shell powder, bamboo fiber, and epoxy resin: 40:30:30, 35:35:30, and 30:40:30. Eighteen specimens were tested. Wear testing was performed using an Ogoshi Wear Tester, while hardness testing was performed using a Brinell hardness tester. The test results showed that the smallest wear rate on brake pads with variations of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin was 0.001107984 mm3/kg.m. The highest hardness level was also in the variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin at 63,0024 kg/. So it can be concluded that the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the lower the wear rate. If the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the higher the hardness level. So it can be concluded that a good brake pad variation is a variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin.

Abstract

This study aims to compare the performance of four types of blades, namely cutter knives, razor blades, wood carving knives, and meat blender knives, on a 220 ml portable plastic packaging shredder. The research was conducted through experimental testing to determine the durability and cutting efficiency of each type of blade under workload during the shredding process. The test results showed that the wood carving knife had the best performance with a cutting force of 1 N, producing the highest number of cuts, totaling 41 plastic cups compared to the other knives. The cutter knife ranked second with 38 cuts, while the razor blade and meat blender knife showed the lowest results. The combination of an optimal wedge angle and low cutting force makes the wood carving knife the most efficient choice for a portable plastic shredder. The results of this study are expected to serve as a reference in selecting effective and economical blades to support small and medium scale plastic waste recycling process.
