Abstract

Rice is one of the staple foods consumed by the people of Indonesia, including the Bangka Belitung Islands Province, more precisely in Bangka Regency, Riau Silip District, Banyu Asin Village. Newly harvested rice is usually not yet separated from the straw/panicle. The rice harvesting process still uses traditional tools or also called gebotan. One example is the rice threshing machine in Banyu Asin Village which has not been able to maximize the threshing results, which results in a long threshing process. The machine is only capable of threshing 30 kg/hour of rice that is put into the machine. Based on these needs, a rice threshing machine design was made to facilitate the threshing process. The design of the rice threshing machine refers to the design method, namely: planning, conceptualizing, designing, and finishing, then assessed based on technical and economic aspects. The designed machine uses a rotary system to thresh rice from its stalks, uses a combustion engine as a driving system, pulleys and belts as transmission elements, and the machine can be moved because it is lighter than existing machines. From the design results, this rice threshing machine has a minimum capacity of 80 kg/hour.

Abstract

A lathe machine is one of the primary machine tools used in manufacturing processes, which rotates a workpiece to facilitate cutting operations with the aid of a cutting tool. The apron and tailstock components on the DoAll Lt. 13 No 03 lathe play a crucial role in maintaining precision and ensuring smooth turning operations. The apron functions to control the automatic movement of the cutting tool along the longitudinal and transverse axes, while the tailstock provides additional support for the workpiece, especially during long turning operations or drilling. Common issues with the apron include wear on the lead screw, whereas the tailstock often experiences misalignment and wear on the bushing thread of the spindle. This study was conducted to repair these damages through disassembly, cleaning, visual inspection, measurement, replacement of damaged components, and realignment. The repair results showed improved machine performance in terms of movement precision and operational stability. By performing regular maintenance and repairs, the lathe machine’s working efficiency can be sustained over the long term.

Abstract

This article discusses the balancing process on a blower using the 4-run method and the balancer feature on the Vibroport 80. The initial vibration measurement of the blower was recorded at 2.28 mm/s, with the impeller weighing 2.5 kg. After adding a 50-gram trial weight at an angle of 0°, the resulting vibration was 0.956 mm/s RMS. At 120°, the vibration measured 2.99 mm/s, and at 240°, it increased to 3.64 mm/s. Based on the calculations performed, a correction weight of 150 grams was determined at an angle of 20°, successfully reducing the vibration to 0.965 mm/s RMS. Using the balancer feature method, the initial vibration value of 1.91 mm/s gradually decreased to 1.36 mm/s after six stages of correction weight application. From the results of both tests, the 4-run method was found to be the most effective for balancing the blower

Abstract

This study aims to design a portable coconut husk shredding machine capable of producing cocopeat, with an emphasis on ease of operation and mobility. The machine is powered by a 7.5 HP gasoline engine and utilizes a shredding system composed of four cutting blades and ten beaters to break down coconut husks into fine cocopeat particles. The design process follows the systematic VDI 2222 method, which includes need identification, concept development, and selection of the final design. The main focus is to create a compact, lightweight, and easily transportable structure without compromising shredding performance. The resulting design successfully meets the operational needs of field users, particularly in terms of portability and user-friendliness. This project was conducted in Bangka Belitung in 2025.

Abstract

Animal feed is an important factor that must be considered to increase the productivity of providing green fodder both in quality and quantity, where in the provision of cattle feed is still done manually using hands with the help of machetes and sickles to chop the feed, especially for cattle breeders of the Puding Jaya II Farmer Group in Puding Village, Merawang District, Bangka Regency. The purpose of this study is to assist in the processing of livestock feed conventionally or manually by designing a chopping machine so that it can make its own cemboran and chopped feed using available materials such as special grass leaves for cattle feed or oil palm leaves so that they are easy for cattle to chew. The method used starts from designing a chopping machine that can be used as a chopping tool for raw materials for livestock feed in the form of odot plants, Indigofera, Chinese petai, jackfruit leaves, elephant grass, palm fronds and leaves which are favorite green fodder for cattle so that it is expected to lighten the burden and make it easier for cattle breeders to get livestock feed that is ready to be eaten by cattle. in an effort to increase livestock feed production can increase as expected to reach 200-300 percent.

Abstract

This Community Service Program aims to address production challenges faced by the Berkah Utama Snack business group, which operates in the fishery processing industry, specifically the production of fish crackers and kemplang (fish crackers). The business group, led by Mrs. Rika Trisdasawati, is located in the Sinar Jaya neighborhood of Sinar Jaya Jelutung Village, Sungailiat District, Bangka. The main challenges faced by partners were limited and worn-out production equipment, including worn and unhygienic fish grinding machines, manual kneading processes, and low-capacity packaging equipment. This resulted in a production capacity of only 10 kg per day, insufficient to meet consumer demand. The implementation method for this activity involved six main stages: (1) identifying partner needs through field observations, (2) designing machines according to technical specifications using CAD software, (3) manufacturing machines at the Polman Negeri Babel Mechanical Workshop with the involvement of technicians and students, (4) operational testing with partners, (5) operational mentoring, and (6) technology dissemination to partners. The results of this activity demonstrated significant achievements in the form of the construction and delivery of three production machines. First, a fish grinding machine with a 40x40 mm L-shaped angle iron frame, a 5.5 HP internal combustion engine, and a pulley-belt transmission system. Second, a stainless steel dough mixer with a 550x450x550 mm dough tube, a Ø30x370 mm screw mixer shaft, and a gear system for heavy loads. Third, a packaging machine equipped with a 1500x800x700 mm table stand. This program has succeeded in increasing partners' production capacity, improving the hygiene of the production process, and reducing dependence on manual labor. In addition, this activity also provides appropriate technology transfer to local communities and strengthens the regional economy by increasing the productivity of fishery product processing business groups.

Abstract

Teknologi pencetakan 3D merupakan inovasi penting dalam industri manufaktur. Salah satu metode yang populer dan terjangkau adalah Filament Fusion Fabrication (FFF) atau Fusion Deposition Modeling (FDM). Namun, pencetakan 3D masih menghadapi masalah akurasi dimensi, yang dapat menyebabkan perbedaan ukuran produk dibandingkan dengan desain. Penelitian ini bertujuan untuk mengidentifikasi parameter yang paling berpengaruh dan optimal terhadap kebulatan produk dengan menggunakan material PETG. Metode Taguchi L9 digunakan untuk mencari parameter optimal dan menganalisis pengaruh parameter proses 3D printing terhadap kebulatan produk PETG. Hasil penelitian menunjukkan bahwa parameter yang optimal untuk kebulatan adalah Layer Height 0.1 mm, Infill Density 120%, dan Print Speed 35 mm/s, dengan nilai S/N tertinggi sebesar 23.7165. Faktor yang paling berpengaruh terhadap kebulatan filamen PETG adalah Layer Height, Infill Density, dan Print Speed.
