Abstract

The hydraulic system has been widely used for various tools. The system developed from Pascal's law becomes one of the vital knowledge that its use in the industrial world. Ranging from small businesses to some kind of a car wash with large industries such as molding machine. The components are arranged in the hydraulic cylinder includes a tube, piston, rod axles, gland, and seal. Each component has the function and role of each and every component seal types are also different types, for a material component of the hydraulic cylinder must not rustproof for hydraulic oil in addition to the driving also serves to lubricate the hydraulic cylinder components. The greater the pressure in the hydraulic tube is getting thicker the hydraulic tube wall, so that the seal does not leak type of profile and material must be in accordance with the state of the hydraulic cylinder, for the connection technique in the hydraulic cylinder components should also be considered such as when welding, welding wire material must be in accordance with the material to be welded. For the methods used in the design of the hydraulic cylinder on the rubber molding machine is an analytical method burdened straight column in the center of axle rodmethods MAWP (Maximum Allowable Working Pressure) to force the tube The results of this design is for a straight column burden in the short-sized center, and to the strength of the tube can withstand the pressure 607.74 bar as well as the costs required to make the hydraulic cylinders in rubber molding machine is very affordable.

Abstract

Ikan adalah komoditi yang tidak tahan lama dan mudah rusak jika ditempatkan di ruang terbuka. Oleh karena itu, para nelayan menggunakan es untuk mendinginkan ikan agar tetap segar. Akan tetapi, cara ini tidak efektif dan efisien karena es cepat mencair, sehingga diperlukan teknologi refrigerasi. Perancangan refrigerated sea water (RSW) ini bertujuan agar dapat digunakan untuk mendinginkan ikan sebagai pengganti es dan mendapatkan sistem pendinginan ikan pada kapal penangkap ikan yang sesuai dengan ukuran palka kapal. Metode yang digunakan dengan observasi lapangan, wawancara dan studi literatur, kemudian dilakukan pengolahan dan analisis data. Dalam perancangan RSW pada kapal ikan kayu lapis fiber 58 GT didapatkan sistem refigerasi yang dipakai adalah sistem refrigerasi kompresi uap, data ruang pendinginan dengan total volume palka 45 m3, menggunakan refrigeran R-22. Jenis kompresor yang digunakan adalah kompresor torak dengan daya kompresor 40 HP, jenis kondensor shell dan tube, beban pendinginan 3,7 x 105 kcal/hours. Untuk evaporator menggunakan jenis evaporator kering, susunan zig-zag, bahan pipa pipa galvanis dengan diameter luar pipa 0,0095 m, diameter dalam 0,0035 m, tebal pipa 0,003 m, jumlah pipa 30 batang, panjang pipa 6 m. Untuk katup ekspansi yang digunakan adalah jenis pipa kapiler. Adapun unjuk kerja atau COP (Coeffisient Of Performance) dari perancangan yang didapat adalah sekitar 4,5078.

Abstract

PT. XYZ is a company engaged in the production of labeling for food and beverage products, fire cases in other factories, reminding the owner to keep his assets safe and comfortable. So it is necessary to plan and design Fire Fighting System to protect the building and its assets. So it is necessary to plan and design Fire Fighting System to protect the building and its assets. This research begins with taking and collecting data in the form of layout of old building condition and layout of new building condition and other technical data needed. Data processing conducted refers to SNI 03-3985-2000, SNI 03-3987-1995, SNI 1745-1989-F, NFPA 13, NFPA 10 and NFPA 14 standards, including design of sprinkler, hydrant and APAR systems (Fire Extinguishers Lightweight) is required, calculate the need for fire water, calculate the total head and pump power required. Based on the result of the research, it is found that the building is classified as light fire hazard and designed using sprinkler type of wet pipe system and the required sprinkler head count is 130 pieces with temperature sensitivity of 57 °C orange glass bulb color, direction emission down, building hydrants as much as 1 piece, page and city hydrants as much as 1 piece, 15 types of dry chemical APAR type and type APAR (CO2) as much as I fruit. The volume of water supply needed for the fire-fighting system is 150 m3. The pipe used is a type of cast iron pipe with total head at the pump of 71.748 meters. The calculation of pump capacity in this planning is 11,576 hp and the originator 14,622 hp.

Abstract

Tujuan penelitian ini adalah membuat modifikasi konstruksi dies untuk meningkatkan kapasitas proses produksi lever comp brake pada PT XYZ yang bergerak dibidang manufaktur otomotif dan engineering. Komponen lever comp brake berfungsi sebagai pengunci handle rem belakang motor matik, biasanya terpasang pada bagian steering. Proses pembuatannya menggunakan mesin Press MC 45 TS. Selama ini dalam proses pembuatan lever comp brake berjalan dengan baik, namun apabila dilihat dari hasil produknya masih kurang effisien. Terutama dari konstruksi awal dies yang mengakibatkan gap pada skrap hasil pierch dan blank yang besar, yang pada akhirnya penggunaan material untuk komponen tersebut terlalu banyak dan membutuhkan waktu pengerjaan yang lama. Berdasarkan penelitian yang telah dilakukan di lapangan, dilakukan perubahan konstruksi dies untuk proses 1 jalur, perbaikan dengan membuatkan guide post yang lebih lebar, yaitu dengan menyesuaikan material untuk proses 2 jalur. Ukuran shearing dibuat lebih lebar, sehingga proses shearing lebih cepat sekitar 14 iris/lembar. Pengambilan material menjadi lebih effisien, karena hasil proses 2 jalur, ± 30 pcs baru ganti material. Data hasil evaluasi proses produksi rata-rata 72,860 pcs setelah dilakukan improvement diperoleh effisiensi sebesar ± 17,86 %.

Abstract This study aims to create a versatile multipurpose machine design to support increasing production of Usaha Masyarakat Kecil Menengah (UMKM), especially in the business of onion slices that are ready to be fried. The design of this machine has several concepts with steps such as: requirement, problem analysis and specification, design of machine concept, technical analysis, modeling up to work drawing, tool making, assembling and testing. This machine uses electric motors with low power and the price is relatively cheap, so this machine is affordable for the community of UMKM. After doing research on slicing machine of onion by using onion slicer got maximum capacity of 55 kg per hour with 400 rpm slicing knife rotation and 1 mm slice thickness. Keywords: Designing, Chopping Machine, Red Onion, Slicer
