Abstract

AbstractCurrently, metal joining techniques in the field of welding have developed rapidly. In constructions that use metal raw materials, most of the joints are made by welding. Apart from joining, the welding process can also be used for repairs, for example to fill holes in castings, make coatings on tools, thicken worn parts and other repairs. Welding is also widely used for building construction, bridges, piping and automotive. As we know, there are many types of welding used today. One of them is Gas Tungsten Arc Welding (GTAW) or commonly called Tungsten Inert Gas (TIG).AISI 1045 steel is referred to as carbon steel because it complies with international coding, namely the 10xx series based on the nomenclature issued by AISI and SAE (Society of Automotive Engineers). The first number 10 is the code that indicates plain carbon, then the code xxx after the number 10 indicates the carbon composition. So AISI 1045 steel means carbon steel or plain carbon steel which has a carbon composition of 0.45%. Steel of this specification is widely used as a component of gears, shafts and bearings. According to its function, it must be able to withstand wear and tear due to friction with the chain. Wear resistance is defined as resistance to abrasion or resistance to dimension reduction due to friction

Abstract

Heat exchangers or often called heat exchangers (HE) are widely used in industry. There are many types of heat exchangers, there are fire pipes or water pipes with cross flow or unidirectional flow. Utilizing exhaust gas is an alternative to reduce costs and increase effectiveness so that wasted energy can be utilized as optimally as possible. A generator is one that can produce electrical energy which produces flue gases with a high temperature so that it can be utilized using a heat exchanger. A shell and tube heat exchanger with a fire tube type was designed. The number of pipes designed was 131 with a pipe diameter of 2.5 inches. The design results obtained from heating water are steam with a capacity of 1 ton. The dimensions of the heat exchanger are 3 meters long with a diameter of 2 meters. The heat energy produced by steam is 2852.2605KW, with a steam temperature produced of 2000C. The resulting LMTD is 360.50K. With this heat exchanger, it is hoped that the costs for producing bias steam will be as minimal as possible

Abstract

Limbah plastik merupakan hal umum yang ada disekitar kita. Penggunaan yang berlebih dapat mempengaruhi dan mencemari lingkungan. Oleh karena itu harus dilakukan proses recycling. Penelitian ini menggunakan metode pirolisis untuk mengubah plastik menjadi bahan bakar. Jenis plastik yang digunakan adalah PET (polyethylene Terephthalate). Pembuatan alat terdiri dari ruang pembakaran, reaktor, pipa penghubung, kondenser dan wadah minyak hasil pirolisis. Metode penelitian ini melakukan proses pirolisis pada temperatur 430⁰C pada waktu reaksi 0-75 menit. Pengujian yang dilakukan menggunakan 3 kg sampah plastik PET dengan pengaturan katup sebesar ¼ , ½  dan 1 yang nantinya akan menghasilkan minyak sebanyak 220 mL dari bukaan ¼ dengan waktu 70 menit, sebanyak 280 mL dari bukaan ½ dengan waktu 60 menit dan 230 mL dari bukaan penuh dengan waktu 75 menit. Dari hasil pengujian dapat ditentukan bahwa hasil yang paling optimal adalah pengaturan katup sebesar ½ karena dapat menghasilkan minyak yang lebih banyak dalam waktu yang singkat.

Abstract

PT XYZ merupakan perusahaan manufaktur elektronik yang sangat bergantung pada komponen coupler tipe "PCV Pipe Cupla Model 3P-V" dalam proses evakuasi udara dan injeksi refrigeran pada sistem pendingin. Penelitian ini bertujuan untuk menganalisis berbagai faktor penyebab penurunan performa coupler serta merancang strategi perawatan yang efektif berbasis Reliability Centered Maintenance (RCM). Metode yang digunakan meliputi identifikasi mode kegagalan melalui Fishbone Diagram dan Failure Mode and Effects Analysis (FMEA), serta pengumpulan data historis kerusakan komponen secara menyeluruh. Hasil analisis menunjukkan bahwa keausan pada shield, patahnya bagian chuck, serta deformasi pada sleeve merupakan penyebab utama kegagalan fungsi. Implementasi strategi RCM, yang mencakup inspeksi visual mingguan, penggantian komponen secara berkala, serta kalibrasi tekanan secara rutin, terbukti mampu mengurangi downtime produksi hingga 40% dan meningkatkan efisiensi proses produksi sebesar 15%. Penelitian ini menegaskan pentingnya pendekatan sistematis dan terstruktur dalam perawatan komponen kritis untuk mendukung kelancaran dan keberlanjutan operasional di lingkungan industri.
