The design of the press tool is one of the practice courses that teach the skill in designing tool forming and cutting the product from the plate. The quality of the design is determined by the ability to apply the design procedure. Competence is widely applied in the design of drawing prints with a certain level of product complexity. Practice activity of designing drawing drawing of students of Engineering Design Program of Mechanical Polytechnic of State of Bangka Belitung done conventionally, where only using drawing table or computerized depiction software then printed on drawing paper. This results in frequent errors in student design drawings. To overcome these problems required drawing prints that can form a specific product such as ashtrays, with the aim of producing a construction drawing print that can be applied and utilized in the teaching of press tool design. The method of making this tool consists of data collection, concept making, tool design, machining & testing. Based on the results of trials that have been done, carried out on 10 blank by using a lubricant in the form of vegetable oil. Of the 10 experiments the formation showed that the central pool of ashtrays can be perfectly formed, while 4 pieces of the grooves on the ear of the ashtray have not been formed well where there are still folds or curves that are not regular.

The utilization of palm frond waste can be processed as animal feed, compost, making briquettes, and basic materials for composite panels. The utilization of palm oil frond waste for various purposes is processed by chopping it into small chunks. The chopping process using a chopping machine makes it easy for farmers and speeds up the chopping time. Several studies have been carried out on the chopping process of palm leaf midribs using different motors and various models of cutting blades, varying motor power, and motor rotation speed in order to obtain the optimal engine capacity. The design method used in the manufacture of the machine is the Pahl Beitz method, namely planning, designing product concepts, designing shapes, and designing details.

Peyek is one of the typical Javanese snacks made from rice flour dough made from peanuts and other ingredients. The results of a survey that was carried out at Mr. Cahyo's residence were slicing 3 kg of peanuts per three days which was carried out with two slicing processes to obtain small slices. The obstacle faced by Mr. Cahyo is the slicing of peanuts which still uses manual tools from wood, where on the big day Mr. Cahyo requires 100 kg of peanuts to be sliced, so it takes a lot of time to finish. The purpose of the design of this peanut slicing machine is to produce thick slices with a size of 3-5 mm in one slicing process. The stages of implementing this final project consist of stages of data collection, planning, calculation analysis, manufacturing process, assembly process, and conducting trials. The result of the design of this machine is that the dimensions of the machine are 300×300×405 mm, and from the trial of this peanut slicing machine, the results are 3-5 mm thick slices, and the data obtained for slicing 500 grams of peanuts takes about 1 minute.

Pantiaw is a typical food originating from Bangka Belitung. The marinade is made from fish and a mixture of other ingredients such as coriander, soy sauce, salt and other flavorings, however, for the process of stirring the pantiaw seasoning, it still uses the manual method. To simplify the process of stirring the pantiaw seasoning, a design for the pantiaw spice mixer was made with a capacity of 10 kg, as well as the SOP (Standard Operating Procedure) and the machine maintenance system, a research method was needed. The method used is the VDI 2222 method which consists of 4 stages, namely planning, conceptualizing, designing, completing. The results of this design process obtained a variant of concept III with a percentage of the technical aspect assessment of 80% and the percentage of economic assessment of 100%. The results of the calculation of the container capacity of 21 kg using a motor power engine of 1 Hp with 1400 rpm, and using a pulley and V-belt belt type A with a shaft diameter of 32 mm and a v-belt length of 1321 mm. The maximum stress that occurs on the shaft diameter of 25 mm is 5 x 10-1 N/mm2

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.

This study aims to design a blanking die used for mass-producing mobile phone holders while prioritizing efficiency and dimensional accuracy. The die set developed includes key components such as the punch, die, stripper, guide post, and fastening bolts. The product produced has dimensions of 138 × 63 × 2 mm and uses ST 37 steel as the raw material. Based on calculations, the required blanking force is 129,000 kN, which is considered safe for the production process. The design also accounts for an optimal clearance of 0.083 mm and a die thickness of 35 mm to effectively withstand the working load. Simulations using stress analysis methods reveal that the von Mises stress distribution on both the punch and die remains below the elastic limit of SKD11 material. The maximum stress on the punch is recorded at 2.437 × 10⁵ N/m², while on the die it reaches 5.153 × 10⁵ N/m², both well below the yield strength of SKD11, which is 2.918 × 10⁸ N/m², indicating that these components operate safely without the risk of plastic deformation. To strengthen the construction, the stripper is designed with a thickness of 12 mm, and the addition of four SCM435 bolts is recommended to improve system stability. This die design is verified through manual calculations and Finite Element Analysis (FEA) to ensure its reliability. Overall, the findings of this study demonstrate that the designed blanking die can support mass production with high precision, optimal structural strength, and long-term durability.
