Abstract

The health condition of the elderly generally has decreased which can cause several physical and mental problems. Elderly aged over 70 years or 60 years who have health problems are categorized as high risk elderly. In carrying out their daily activities inside the house or outside the house, such as going to the mosque, garden, etc., they usually use a equipment called a walker. The types of walkers on the market still have limitations, so they need to be developed in a flexible walker design. The stages used in the flexible walker design development research are compiling a list of requirements, determining reference concepts, developing alternative concepts, selecting concepts, and analyzing techniques and postures for the selected design. The selected concept has specifications, namely the front pedestal functions as a fixed leg or wheeled leg, the arm of the walker holder can be adjusted up and down by 150 mm in height, has a seat that can be folded, and the walker can be folded. In addition, the results of stress analysis on the critical component, namely the main fulcrum, obtained safe criteria where the maximum stress value that occurs is 7.35x106 N/m2 is given still below the yield strength value of the brass material 3.5x108 N/m2. Posture analysis using the RULA method in standing and sitting positions obtained an average final score of 2 in the acceptable category for walker users..

Abstract

Fried onions made from shallots are an important type of horticultural crop and are very often used by the public. The process of making fried onions is carried out in several stages until it becomes fried onions that are ready to be consumed, starting from peeling the onion skin, slicing, frying, draining and packing. From the results of a survey conducted on partners, the process of slicing onions is still done manually using a slicing tool made of wood. Mrs. Yuliana, who currently produces fried onions, reaches 10 kg/day for Monday - Thursday, and Friday - Sunday 15-20 kg/day, and for religious holidays usually the capacity produced can reach 60 kg/day, with a total on average 500 kg per month, you have to replace the slicer every 4 months. The tool currently used to slice onions has a capacity of 10 kg/hour, so it requires more energy and time for the slicing process. In order to increase the production of shallots and produce slices as is done today, a shallot slicing machine was developed with a slicing system similar to the tool used. Partners receive appropriate technology in the form of shallot slicing machines and training on the process of using the machine and maintaining the machine. Apart from that, a monitoring and evaluation process is also carried out to measure the level of success and obstacles to the machines used by partners. After developing a red onion slicing machine, partner production productivity increased, the machine can function well and is capable of peeling 2.5 kg of red onion skin in 4 minutes in one process or 37.5 kg/hour.

Abstract

Nipa plant is a plant that can be found in water areas such as in swamps. Quite a lot that can be utilized from this swamp plant. Utilization of the nipa plant can be sourced from its fruit, midrib, and leaf bones [1]. In addition to the uses previously described, the nipa plant in its midrib has fiber which has been extensively researched on this fiber. Nipa midribs which have fibers can be used as reinforcement for fiber composites. This study aims to determine the effect of arrangement and volume fraction of fibers that have been determined, as well as knowing whether the use of nipa midrib fiber as a composite reinforcement material can or cannot achieve the tensile strength value of the high impact ABS plastic material on the car dashboards. The research method in this study uses factorial design with manual composite printing. The results of this study were that the highest value of the tensile strength of the nipa midrib fiber composite was found in the vertical arrangement direction with a volume fraction 15%, namely 26.43 MPa, while the lowest value is found in the direction of horizontal arrangement with a volume fraction of 15%, namely 14.07 MPa. So that the value of the nipa midrib fiber composite in the vertical arrangement direction with a volume fraction of 15% achieves the tensile strength value of the high impact ABS plastic material on the car dashboards, namely 20 – 40 MPa.

Abstract

Wood as the main raw material in making furniture causes the need for wood to increase while in its processing almost 30% of wood is wasted into waste just like that. In overcoming these problems, it is necessary to conduct research for the utilization of waste used for wood processing. Limited equipment in the manufacturing process becomes an obstacle to be one of the causes in the development of particle board products into a household industry. This research tried to make particle board with simple tools. This study used several parameters, namely 80:20, 70:30, 60:40, d and pressures of 7kg, 5kg, 3kg. The test results obtained the physical properties of wood dust composites with the Pva matrix, the lowest value was obtained at a variation of 80:20 pressure 7kg of 17.528% and the highest value at a variation of 60:40 pressure 7kg 117.237%. That the use of more matrices can inhibit water absorption is evidenced by micro photos at the 80:20 variation where the audience is no more than 25%. In the 60:40 variation, the use of more powder causes the glue bonding in this variation not to cover the powder as a whole like the 80:20 variation. Therefore, absorption at 60:40 is greater than at 80:20.

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 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.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi suhu nozzle dan ketebalan lapisan (layer height) terhadap kekuatan tarik material Polypropylene (PP) yang diproduksi menggunakan teknologi Fused Deposition Modeling (FDM). Metode Taguchi L9 Orthogonal Array digunakan untuk menentukan kombinasi parameter proses yang paling optimal dengan jumlah percobaan yang efisien. Pengujian kekuatan tarik dilakukan menggunakan Universal Testing Machine (UTM) berdasarkan standar ASTM D638-14 tipe IV. Hasil penelitian menunjukkan bahwa peningkatan suhu nozzle berpengaruh signifikan dalam memperkuat ikatan antar-lapisan, sehingga meningkatkan nilai kekuatan tarik material. Sebaliknya, peningkatan ketebalan lapisan menyebabkan penurunan sifat mekanik akibat lemahnya adhesi antar-layer. Kondisi optimum diperoleh pada suhu nozzle 250°C dan ketebalan lapisan 0,1 mm, dengan nilai kekuatan tarik rata-rata mencapai 55,7 MPa. Analisis Signal-to-Noise Ratio (S/N) menunjukkan bahwa suhu nozzle memberikan kontribusi dominan terhadap kestabilan dan kekuatan hasil cetakan. Secara keseluruhan, penelitian ini memberikan kontribusi terhadap optimasi parameter proses FDM berbasis material PP, terutama untuk mendukung peningkatan efisiensi dan performa mekanik pada aplikasi industri manufaktur aditif.
