In the world of the manufacturing industry, developments and needs are increasing every day and very rapidly. Many parts and components in automotive production are very important and very much too because each component has its own function and use. There are many alternatives and development of materials for component manufacturing in the automotive world which aim to cut production costs and efficiency. To overcome this condition, the authors tried to research and make a Mold for the Avansa car door handle using HIPP (High Impact PolyPropilane) material. Generally, not many HIPP use it in the automotive industry. Making this door hendle using the Hot Compression process. Among other things, hot compress is the process of making a product by using heat and pressure to form the desired product. So far, making molding is less precise because mold making is not in accordance with the manufacturing process, therefore the author uses a CNC (Computer numarical control) machine for this molding-making process, the molding process using this CNC machine aims to make the results more precise and more accurate. more as desired.

The development of science and technology has an important role in the success of development in the industrial sector. In the industrial world, machining processes are very important. A scrap machine is a machine tool that is used to change the surface of a workpiece into a flat surface with levels, corners and grooves.This research aims to find out the causes of damage to the automatic movement of the table, to determine the strength of the material using impact testing and calculating torsional moments, and to be able to repair damage using the welding method using brass. Damage that occurs to the automatic movement of the table is caused by the final limit of the moving table being exceeded. On a sledding table there is no final limit for the moving table, when the final limit for the moving table occurs, the automatic moving machine continues to work and exceeds the material strength limit of 14,133 joules and 1422 N.m, causing the nut to be damaged. Repairing the sliding table nut is done by welding. This welding is carried out using brass, brass is used because it has high wear resistance. Keywords: Scrap Machine, torsional moment, impact test, cause of damage.

Dalam proses produksi salah satu kegiatan yang umum adalah material handling yaitu penanganan atau pemindahan bahan baku dari satu proses ke proses yang lainya. Proses pemindahan material atau material handling dibutuhkan pesawat angkat dan angkut. Salah satu pesawat angkut yang digunakan adalah mesin Screw conveyor. Mesin digunakan untuk memindahkan material berupa clay yaitu berupa butiran butiran tanah yang sudah dikondisikan dengan ukuran tertentu yaitu berukuran 5mm sampai 30mm. Bagian pada mesin ini yang sering mengalami kerusakan adalah bagian bearing, hal ini dikarenakan semua beban untuk mendorong material bertumpu langsung dengan bearing. Untuk menentukan kekuatan bearing yang dipakai maka harus dibuat dulu rancangan dasar dari mesin tersebut, yaitu kapasitas mesin, jenis material, gaya yang bekerja pada bagian bearing. Disini telah didapatkan data kapasitas mesin screw conveyor adalah 11.000 kg/jam, kekuatan bearing secara perhitungan yaitu Bearing QJ304: 15.637 jam, Bearing NU304: 38.683 jam, dan Bearing 22316: 50.937 jam. Untuk mendapatkan kondisi aktual bagian bearing yaitu pengukuran vibrasi. Dalam hal vibrasi alat ukur akan menunjukan besarnya velocity. Velocity adalah jumlah waktu yang dibutuhkan ketika terjadinya displacement atau kecepatan getaran suatu benda. Secara garis besar Velocity mewakili kondisi kerusakan bearing yang diaktualisaikan dengan niali 0-11 yaitu merujuk pada Standard ISO 10816-3. Sehingga akan didapatkan hasil perbandingan dari perhitungan perencanaan mesin dan aktualnya.

A pressure vessel is a place or container for storing or building fluids, both in the form of liquids and gases as one of the process tools used in industry, especially in the chemical, petroleum, and electricity generation industries with steam separators which are very important components in electricity generation. The steam separator is used to separate the fluid in the liquid phase and gas phase (steam or steam) to produce a higher level of dryness and more contained in the steam that will be used to turn the turbine. Based on the ASME VIII standard in 2010 which was a vessel before it could be used in payment and one type of testing was by hydrostatic test method. From the calculation of the voltage that occurs when hydrostatic administration is 5.037 MPa (50.37 Bar), the force that divides the locked flange 8 bolts M-16 x 2.0 (P), with the introduced voltage (τ) inside the pressure vessel, at what is permitted τ (that occurs (40 N / mm2 ≥ 36 40 N / mm2. from the test results using hydrostatic test methods obtained for hydrostatic testing can determine leakage and test with 1.5 x work work (30 bar) steam separator pressure vessel no defects appear, crank on the weld or deformation occurs. Key words: Hydrostatic, Pressure vessel, Steam Separator.

Kopling merupakan salah satu komponen mesin slitting yang berfungsi untuk memutuskan dan menghubungkan putaran daya mesin ke unit pemindah tenaga atau transmisi dengan tujuan mengubah kecepatan sesuai yang diinginkan. Adapun permasalahan yang diakibatkan kopling ialah kegagalan patah pada kopling. Untuk mengetahui permasalahan kegagalan patah pada kopling ada beberapa pengujian yang dilakukan, diantaranya dengan pengujian spektrometer, pengujian kekerasan dan pengujian metalografi. Pengujian dilakukan untuk mengetahui nilai kekerasan pada material kopling akibat pembebanan yang terjadi pada kopling. Pengujian dilakukan dengan membandingkan material kopling dengan material S45C menggunakan metode heat treatment dengan variasi media pendingin. Hasil dari penelitian yang dilakukan menunjukan bahwa terdapat perbedaan nilai kekerasan antara material kopling dengan material S45C, dimana hasil pengujian material kopling menghasilkan nilai kekerasan rata-rata 97 HRB sedangkan pada material S45C menghasilkan nilai kekerasan rata-rata 88,9 HRB, berdasarkan perubahan fasa ferrite, pearlite dan martensite hasil pengamatan metalografi.

The fossil fuel crisis in Indonesia, which contributes 85% of the national energy mix, has driven the need to utilize renewable energy sources, one of which is exhaust wind as industrial waste energy that has high speed (5-7 m/s) and good flow continuity. This study developed a vertical Savonius turbine with variations in exhaust-turbine distance (20, 30, 40 cm) and measured wind speed (5.3, 6, 6.4 m/s) to optimize the utilization of this energy. The results showed that the 20 cm configuration produced the best performance with a maximum power of 5.98 watts at a speed of 6.4 m/s and a Coefficient Performance (CP) of 0.16, which is 31% more efficient than a distance of 40 cm, proving the potential of exhaust wind as a renewable energy solution that is applicable in industry with a payback period of less than 3 years and the potential for reducing the load on the electricity network by up to 15%.

The metal coating process plays an important role in improving the corrosion resistance and service life of products. One of its main components is the main pot, a refractory container that holds aluminum, zinc, and silicon alloys at high temperatures. The temperature stability of the coating fluid is highly dependent on the performance of the inductor as the main heat source. The problem encountered is that the inductor's capacity is not yet optimal in maintaining the operating temperature, thereby affecting the efficiency of the process and the quality of the coating results. This study aims to analyze the inductor's ability to maintain the main pot temperature, identify factors that affect heating efficiency, and provide recommendations for improving system performance. The methods used include measuring the liquid temperature, recording electrical power, and observing the decrease in coating volume. The results show that four inductors with a total capacity of 1800 kVA only meet about 20–23% of the energy requirements. The fluid temperature can be maintained in the range of 602–608 °C, but tends to decrease over time. The coating volume decreased by an average of 8.05–11.61% during five hours of operation. Increased power capacity and a periodic refill strategy are needed to maintain temperature stability and coating efficiency.
