Abstract

Abstrak-- Mesin kompaksi merupakan sebuah alat yang berfungsi untuk memadatkan material komposit serbuk serat alam matriks polimer. Umumnya, pada pembuatan material komposit secara manual hanya menggunakan kandungan serat tidak lebih dari 10% sehingga sifat mekanis yang didapat tidak meningkat. Oleh karena itu, material komposit perlu dikompaksi menggunakan mesin kompaksi agar kandungan seratnya dapat ditingkatkan dibandingkan dengan kandungan polimernya supaya sifat mekanisnya dapat meningkat. Salah satu komponen penting dari mesin kompaksi yaitu dies dan punch yang berperan penting dalam pembentukan material. Oleh karena itu, komponen dies dan punch perlu dibuat sesuai dengan kebutuhan. Dalam pembuatan dies dan punch, proses perakitan dan manufaktur mempunyai peranan penting. Penelitian ini bertujuan untuk merancang komponen dies dan punch dengan 3 variasi desain yaitu desain 1, 2, dan 3 untuk ditemukan desain yang terbaik serta efisien. Pembuatan dies dan punch dilakukan dengan menggunakan konsep Design for Manufacturing and Assembly (DFMA). Konsep DFMA ditujukan untuk mendapatkan jumlah komponen, dan waktu perakitan yang paling efisien. Penelitian ini mendapatkan hasil desain yang terbaik yaitu desain 3 dengan jumlah komponen 4 part, efisiensi sebesar 19,63%, serta estimasi biaya manufaktur sebesar Rp1.278.500,00. Sedangkan desain 1 dan 2 memiliki jumlah komponen 7 part dan 5 part, efisiensi desain sebesar 26,78% dan 13,54%, dan estimasi biaya manufaktur sebesar Rp2.361.630,00 dan Rp2.160.000,00. Hasil desain 3 ini dapat mereduksi jumlah komponen sebesar 3 part, meningkatkan efisiensi desain sebesar 6,09%, serta mereduksi biaya manufaktur sebesar Rp1.083.130,00. Kata kunci: Komposit, Desain, Dies dan Punch, DFMA, Rancangan yang Efisien Abstract-- Compaction machine is a tool that serves to compact the polymer matrix natural fiber powder composite material. Generally, the manufacture of composite materials manually only uses fiber content of no more than 10% so that the mechanical properties obtained do not increase. Therefore, composite materials need to be compressed using a compacting machine so that the fiber content can be increased compared to the polymer content so that the mechanical properties can be increased. One of the important components of the compacting machine is the dies and punches that play an important role in the formation of the material. Therefore, dies and punch components need to be made as needed. In making dies and punches, the assembly and manufacturing process has an important role. This research aims to design dies and punch components with 3 design variations, namely design 1, 2, and 3 to find the best and efficient design. Making dies and punches is done using the concept of Design for Manufacturing and Assembly (DFMA). The DFMA concept is aimed at getting the most efficient number of components, and assembly time. This study obtained the best design results, namely design 3 with the number of components of 4 parts, efficiency of 19.63%, and estimated manufacturing costs of IDR 1,278,500.00. While designs 1 and 2 have the number of components of 7 parts and 5 parts, design efficiency of 26.78% and 13.54%, and estimated manufacturing costs of IDR 2,361,630.00 and IDR 1,278,500.00, respectively. Keywords: Composite, Design, Dies and Punch, DFMA, Efficient Design

Abstract

Pipa merupakan alat yang digunakan untuk memindahkan fluida. Di dalam proses penggunaanya terdapat rugi-rugi aliran yang terjadi. Kerugian tersebut dapat diakibatkan oleh berbagai variasi desain yang berkaitan dengan ukuran dan jalur alirannya. Rugi-rugi yang terdapat pada aliran pipa dikenal dengan rugi mayor dan rugi minor. Rugi mayor terjadi karena terdapat gesekan aliran fluida dengan dinding pipa, sedangkan rugi minor terjadi karena adanya belokan ataupun percabangan aliran. Bukan hanya pada desain aliran saja, Kerugian yang telah disebutkan diatas tentunya mempengaruhi kinerja pompa sebagai pemasok aliran fluida. Apabila gesekan terlalu besar kemungkinan besar pompa tidak akan maksimal dalam menjalankan tugasnya. Permasalahan terebut menyebabkan kasus rugi-rugi aliran dalam instalasi pipa terus dipelajari dan dilakukan pembaharuan. Dalam penelitian ini  dilakukan peninjauan penelitian terdahulu mengenai rancang bangun alat uji rugi-rugi aliran pada instalasi pipa. Dalam tinjauan ini metode, desain, dan aspek lainnya yang mempengaruhi rugi-rugi dalam aliran dipelajari dan disatukan menjadi rangkuman penelitian. Setelah dikumpulkan materi-materi tersebut kemudian dipelajari lebih lanjut sehingga didapatkan hasil yang berupa peluang pengembangan dan inovasi yang berkaitan dengan rancang bangun alat uji rugi-rugi aliran dalam instalasi pipa. Pengembangan dan inovasi terbaru kemudian dituangkan dalam bentuk jurnal tinjauan tentang rancang bangun alat uji rugi-rugi aliran pada instalasi pipa

Abstract

Salah satu penyebab dari kerusakan pada komponen mesin adalah disebabkan oleh kelelahan, yaitu kegagalan pada material akibat beban/ tegangan berulang – ulang (Cylic stress) meskipun besarnya tegangan tersebut masih di bawah batas kekuatan elastiknya. Karenanya, kelelahan, khususnya pada komponen mesin merupakan sifat yang sangat penting untuk dikaji dan diteliti. Salah satu komponen mesin yang mengalami beban berulang-ulang adalah poros. Akibat beban-beban yang bekerja pada poros meskipun jauh di bawah tegangan luluhnya, poros dapat mengalami kelelahan. Karenanya sebuah poros perlu diuji sifat lelahnya untuk memperkirakan umur poros tersebut saat digunakan nantinya. Pada poros yang berputar ada yang mengalami beben lentur ada yang tidak. Adanya beban lentur pada poros kemungkinan akan menambah pendek umur siklus lelah dari poros. Tujuan dari penelitian ini adalah: Menguji Bagaimana pengaruh beban lentur terhadap umur siklus fatik dari poros Stainless steel SUS 304 untuk kemudian mendapatkan hubungan antara momen lentur yang diberikan dengan umur siklus dalam bentuk persamaan matematis. Pengujian dilakukan untuk 7 macam variasi  beban, mulai dari beban 1kg, 1,5kg, 2kg, 2,5kg, 3kg, 3,5kg dan 4 kg, yang mana beban yang diberikan tersebut akan dirasakan sebagai beban lentur oleh poros. Hasil pengujian ini membuktikan bahwa besarnya beban lentur yang dialami oleh suatu poros stainless steel berpengaruh terhadap umur kegagalan fatik poros tersebut, yang mana, semakin tinggi beban yang diberikan maka umurya semakin pendek. Pengujian spesimen dengan diberi beban terendah sebesar  1 kg yang menghasilkan momen lentur sebesar  0,882 N.m dan tegangan geser sebesar 41,6 Nm, poros dapat beroperasi hingga 32820 siklus. Beban maksimum sebesar 4 kg menghasilkan momen lentur sebesar 3528 Nm, dan tegangan geser sebesar 166,45 N/m² dan kegagalan poros terjadi pada siklus 3702.

Abstract

Piping installation is a medium for fluid transfer which has many design variations. The design used can affect the flow rate of the fluid. The effect comes from head losses which are divided into major losses and minor losses. Basically, major losses are losses caused by straight pipes while minor losses are losses due to pipe components. These components can be in the form of bends, connections, branching and changes in cross-sectional size. Losses that occur in pipe flow can be studied by direct simulation. To carry out a direct simulation, a test tool is needed that can help analyze losses that occur in fluid flow in pipe installations. The design that is carried out refers to the use of pipe installations that are often encountered including its components. The system design of the flow loss test equipment is selected using the VDI 2221 method. The selection of components is carried out by comparing the variations in the arrangement of system components. From the results of this comparison, the best variation was obtained with the results of the main PVC pipe, 108 bit Shimizu jet pump, ball valve type, pressure gauge capacity of 2.5 bar, flowmeter capacity of 1.5 m3/h, rotameter capacity of 2-20 GPM/10- 70 LPM. The tool has been completed built and tested so it is feasible to use.

Abstract

Steel has various physical and mechanical properties. The very high hardness of steel makes it difficult to form or process with a machine. Based on these problems, there needs to be a treatment (treatment) that can improve the mechanical properties of steel. The annealing process is the process of heat treatment of metals or alloys by heating the metal to austenite temperatures, holding it at that temperature for a while, and cooling the metal at a very slow cooling rate. The heat treatment process aims to improve the mechanical properties of the metal or alloy. In this study, SUH 35 steel was used as the test material. Eight test materials are prepared, namely four materials Unannealed and four materials treated with annealing. Annealing specimens are given heat treatment with a temperature of 750 ° C ± 10 ° C with a holding time of 60 minutes. This specimen is carried out by turning process with variable machining feeding that varies 0,25 mm/revolution, 0.50 mm/revolution, 0,75 mm/revolution, and 1 mm/revolution. The results of this study show that the annealed material has a lower roughness value of 311.49 VHN. In comparison, the Unannealed sample has a hardness value of 607.59 VHN, which shows better machinability in the annealed material. The results of the feeding variation show that the greater the feeding value, the more it will affect the increase in the roughness, resulting in the surface grinding process.

Abstract

Piping systems are a major component in oil and gas processing facilities in Indonesia. With piping usage increasing every year, safety is a critical priority to avoid fatalities and losses due to piping damage. In order to ensure safety and reliability, a thorough analysis of piping stress analysis is required at design and operation stages. Piping stress analysis aims to assess the risk of stresses arising from various factors, including changes in temperature, internal pressure, and external environmental conditions. This study conducted a literature review of 51 international journals published between 2014 and 2024, focusing on factors that affect piping stresses analysis such as force loads, pipe support, piping layout, vibration, earthquake, and cryogenic service conditions. Based on this study, it was found that force load pressure & temperature, determining pipeline layout, pipe support location and vibration have a impact on pipe stress distribution, which in turn affects piping reliability and service life. Analysis using software such as CAESAR II proved effective in identifying critical areas on the piping and ensuring that the system performs in accordance with established safety standards. The review shows that piping stress analysis not only maintains safe operational limits but also improves piping reliability. With proper application of stress analysis, the risk of failure can be minimized, and the service life and reliability of the pipeline system increased. This application is important to maintain production continuity and minimize potential losses due to damage to the piping infrastructure.

Abstract

This research aims to assess carbon fibre's physical and mechanical properties and potential use to improve vehicle efficiency. The main focus is to reduce vehicle weight, improve fuel efficiency, and lower carbon emissions. Carbon fibre has a tensile strength of more than 6 GPa, a modulus of elasticity of more than 600 GPa, and a density of 1.8-2.0 g/cm³. Its use in vehicles can reduce weight by 86%, improve fuel efficiency by 20%, and significantly reduce carbon emissions. The carbon fibre sandwich composite structure with an aluminium honeycomb core increases strength and reduces weight by 36%. Carbon fibre also improves the vehicle's rollover resistance by 64% and energy absorption by 60%. However, high manufacturing costs are a major challenge, with precursor materials such as polyacrylonitrile (PAN) accounting for about 50% of the cost. Biomass-based alternatives, such as lignin and agricultural waste, can reduce costs, although they require further development. Research shows that integrating recycled carbon fibre in metal-polymer hybrid structures can reduce vehicle weight by 48% and improve structural performance. This research emphasizes the importance of manufacturing innovation and the exploration of alternative materials to maximize the utilization of carbon fibre.
