Abstract

The rate of transportation development in Indonesia faces a significant increase. However, the increase in transportation rates is not in line with the increase in residents, especially for people with disabilities. One form of discrimination against people with disabilities is the lack of accessible transportation equipment for wheelchair users. The lack of service facilities makes people with disabilities feel insecure. The lack of facilities provided makes people with disabilities choose to use individual vehicles to continue activities like normal people. The purpose of the research on providing transportation facilities for people with leg disabilities is very much needed in carrying out daily activities easily and without obstacles. The design of a wheelchair user disability vehicle uses the VDI 2222 design method with 4 stages, namely planning, conceptualizing, designing, and completing. From the conceptualization session, 3 design concept variations were generated which were then assessed based on technical and economical aspects. From the test results that were tested, the average speed that can be reached by this wheelchair user disability vehicle is 30 kilometers / hour.

Abstract

In production machining process is something that must be prioritized. One factor that affects the quality of production is the condition of the machine tool. The Mori Seiki SL 25 CNC Turning Machine is a machine that has existed since 1998 at the Polman Babel Mechanic Workshop and has been used for production processes and learning facilities for approximately 25 years. The use of machine tools at that time can affect the machine's geometric conditions, affecting the quality of the product produced. Roundness is one of these geometric conditions because many components with round cross-sections affect the components' function if deviations occur. Deviations in the roundness value on the machine can be known by testing the roundness value of the machining workpiece. From these tests, geometric errors in the machine and the feasibility of the machine in processing workpieces at specific size tolerances can be seen. The workpiece resulting from the machining process will be measured for its roundness value and then analyzed using the Minimum Zone Center (MZC) method. The test results on the geometric conditions of the machine are that the highest roundness deviation is at position 1 with an average of 21.7 μm which is the outermost position of the clamping area. The slightest deviation value is at position 6 with an average of 10.9 μm, and the machine can produce workpieces with a tolerance above 21 μm.

Abstract

In the current era, the automotive industry is growing rapidly, one of which is in the field of transportation in the manufacture of brake linings. Generally, brake linings are made of materials containing asbestos which endanger health. Therefore, a material innovation is needed to replace the role of asbestos such as aluminum matrix composites. The purpose of this study was to determine the effect of different hot compaction pressures on the density and hardness of AMC reinforced with SiC and RHA. The method used in this research is powder metallurgy method, which consists of preparation, mechanical mixing, compacting, and sintering stages. The mixing process uses a ball mill machine with ball ratio parameters of 10:1 and stirring time for 2 hours and with a rotating speed of 90 rpm. The compacting process is done by two-way pressing from a hydraulic press machine with a pressure gauge. In this process the parameters used are 5600 PSi, 6000 Psi and 6400 Psi pressure with a holding time of 15 minutes. Density testing was done with ASTM B962-17 according to Archimedes' law. Hardness testing using ASTM E110-14 with a portable brinell hardness tester. The test results show that the higher the compaction pressure, the higher the density and hardness values. With the highest density value of 1.69 g/mm3 and the highest hardness value of 39.33 HB for specimens with 6400 Psi compaction pressure parameters.

Abstract

Pemanfaatan limbah pelepah sawit dapat diolah sebagai pakan ternak, kompos, pembuatan briket, dan bahan dasar panel komposit. Pemanfaatan limbah pelepah kelapa sawit untuk berbagai tujuan tersebut diproses dengan cara mencacahnya menjadi cacahan berukuran kecil. Proses pencacahan dengan menggunakan mesin pencacah memberikan kemudahan bagi petani dan mempercepat waktu pencacahan. Beberapa penelitian telah dilakukan pada proses pencacahan pelepah daun kelapa sawit  dengan menggunakan motor penggerak yang berbeda-beda dan berbagai model pisau potong, daya motor, serta kecepatan putaran motor yang bervariasi dengan tujuan untuk mendapatkan kapasitas efektif mesin yang optimal. Metode perancangan yang digunakan dalam pembuatan mesin adalah metode Pahl dan Beitz, yaitu perencanaan, perancangan konsep produk, perancangan bentuk, dan perancangan detail. Parameter yang diamati dan diukur pada mesin adalah kapasitas efektif mesin, rendemen cacahan, dan ukuran panjang hasil cacahan. Uji coba dilakukan sebanyak tiga kali pengulangan dengan mencacah pelepah yang ditimbang masing-masing seberat 5 kg. Hasil uji coba terhadap mesin pencacah pelepah kelapa sawit sistem rotary menunjukkan bahwa kapasitas efektif mesin rata-rata adalah sebesar 244,06 kg/jam sehingga termasuk dalam katergori kelas A. Rendemen cacahan rata-rata pada mesin adalah sebesar 97 % dan ukuran rata-rata cacahan ≤ 50 mm adalah sebesar 89,5 % dan telah memenuhi syarat SNI 7580: 2010.

Abstract

Public services should be accessible to all citizens, including persons with disabilities. However, they still face various forms of discrimination, particularly in terms of physical accessibility and neutral public service policies that do not accommodate their needs. One of the major challenges is the difficulty in using public transportation, which significantly affects their mobility, employment opportunities, and social interaction. This final project aims to design a vehicle door that is accessible and user-friendly for wheelchair users, with a focus on enhancing independent mobility. The design process refers to the VDI 2222 methodology, starting from identifying user needs, developing design concepts, to evaluating the proposed solution. One of the main issues in conventional vehicle design is the door mechanism, which often fails to consider the specific needs of wheelchair users. Common problems include narrow door openings, high floor levels, and unfriendly opening-closing mechanisms. This study proposes several modifications, such as wider door openings, lower floor height, and the use of sliding or automatic doors to improve accessibility. The proposed design is expected to offer a practical and applicable solution that enhances the mobility and quality of life of people with disabilities, especially wheelchair users, in Indonesia.
