Abstract

Excavator merupakan alat berat yang biasanya banyak dipergunakan di dunia pertambangan, proyek pembangunan, khususnya excavator komatsu PC200-8. Setiap excavator memiliki pompa hidrolik yang berfungsi untuk memindahkan cairan oli hidrolik dari tangki ke setiap silinder. Tujuan dari penelitian ini untuk mengetahui daya pompa hidrolik excavator, besar daya boom excavator saat melakukan gerakan, dan untuk mengetahui daya pada arm excavator. Untuk mendapat nilai daya maka dilakukan juga perhitungan pada tekanan maksimum pompa hidrolik, Aliran (flow) pompa hidrolik, dan daya pompa hidrolik. Metode yang digunakan ada beberapa cara dengan wawancara pada bagian mekanik, melakukan observasi langsung pada saat excavator melakukan kerja, dan data yang diambil tahun 2020. selanjutnya dilakukan perhitungan untuk mendapatkan daya setiap alat pada excavator. Dari perhitungan yang dilakukan maka didapatkan hasil tekanan maksimum pada dua pompa hidrolik 3,72 x 107(N/m2), aliran pompa hidrolik 3,66 x 10-3m3/s, daya yang dihasilkan 272,30 kW. Hasil perhitungan cylinder boom untuk tekanan maksimum 3,48 x 107, aliran cylinder boom 4,18 x 10-4. Hasil perhitungan tekanan maksimum Cylinder arm 3,48 x 107, aliran fluida cylinder arm 5,57 x 10-4. Dari hasil perhitungan maka dapat disimpulkan tekanan maksimum pada pompa hidrolik dapat menghasilkan daya yang besar. Tekanan pada cylinder boom yang kecil akan menghasilkan daya yang kecil demikian juga pada cylinder arm tekanan yang dihasilkan lebih besar dari cylinder boom.

Abstract

Indonesia is an industrial country that uses a lot of shafts as one of the important components in the production process. The shaft is one part of the rotating machine element whose function is to transmit power from one place to another. Shaft damage is one of the problems that often occurs, especially in the maintenance process that is not carried out according to factory standards or is not orderly in carrying out engine maintenance. The process of changing the shaft is expensive and the new material is sometimes not up to factory standards. Moving on from these problems, the author will design a shaft straightening machine with a rotation system. Previous research conducted by Juan Zhou designed a hexagonal axis straightening machine, but the hexagonal model still has a number of errors in its operation. The shaft straightening machine with the rotation method is expected to minimize errors and improve the shaft with better physical and mechanical properties after going through the heat treatment process with a rotation system

Abstract

This study aims to determine the effect of variations in welding current on the tensile strength and toughness of GTAW welds with ER70S-60 electrodes. The materials is welded with a current of 70 Ampere, 100 Ampere, and 130 Ampere by GTAW AC/DC reverse polarity welding using ER70S-60 electrode with a diameter of 2,4 mm X 1000 mm. AC/DC reverse polarity, ie the electrode wire holder is connected to the positive pole and the negative The type and base metal is connected to the negative pole. The type of seam used is V seam with and angle of 70°. This specimens were subjected to tensile test and impact tests. The highest tensile strength for the weld area occurs in the 130 Ampere specimen is 52.98 kgf/mm², this means an increase of 3.47 kgf/mm2 from the normal specimen and also by 6.10 kgf/mm2 of a 100 Ampere specimen. The toughness in the highest weld area on the 130 Ampere specimen is 4.03 Joules, the 70 Ampere and 100 Ampere currents have decreased to 70 Ampere currents, which are 2.69 joules and 0.009 joules, respectively. From the results of the study it can be conluded that variations in welding currents there is a change in the structure due to strength of the material, namely an increase in normal specimens.

Abstract

Pengeringan mekanis masih sangat jarang penggunaannya di masyarakat, serta kadar air produk yang dihasilkan tidak seragam disebabkan tidak adanya pengontrolan suhu pemanasan. Dari masalah yang dihadapi perlu ada pengering mekanik yang dapat membantu proses pengeringan lebih cepat dan dilengkapi kontrol suhu sehingga kadar air produk yang dihasilkan seragam. Peralatan pengeringan yang peneliti buat adalah pengering jenis rotary dryer dengan lampu halogen sebagai sumber panas dengan variasi suhu dikontrol menggunakan PID temperature controller. Mesin pengering padi ini memiliki dimensi 2039 mm x 800 mm x 980 mm dengan waktu pengeringan pada silinder rotary adalah 15 menit 49 detik. Data yang dihasilkan setelah dilakukan pengeringan padi 5000 gram pada suhu 50°C adalah terjadi penurunan kadar air padi sebanyak 3,26 %, adapun pada suhu 75°C terjadi penurunan kadar air padi sebanyak 9,04 %, sedangkan pada suhu 100°C penurunan kadar air padi yang terjadi sebanyak 13,24%.

Abstract

The manufacturing process in the automotive industry is in dire need of resistance spot welding machines. Because it was easier to use, highly effective, and effective in functioning. However, there were sometimes still connection problems that were still of poor quality, both nuggets and areas that are subject to electrode pressure. To get a quality welding connection, a machine was needed that was able to carry out good material preparation in the form of sanding, able to set the welding current analogously, able to set the time with an automatic timer, able to apply pressure on the electrode measurably during the welding process. The research aimed to design a prototype of resistance spot welding material preparation that could adequately carry out material preparation and welding using a Bluetooth system connected to a mobile phone. The research methods carried out were as follows: first, designing the machine using Autodesk Inventor software, then the device was made with a focus on material preparation prototypes, then the machine elements were made for the material clamping rail, then the machine elements in the control section using Bluetooth connected to the mobile phone, the machine was tested, then the connection quality testing process was carried out on the tensile testing machine. The results showed that the design results had been made using elbows and iron plates with threaded rails with a length of 650 mm, which became material clamping rail grooves with a drive using window motors controlled by Bluetooth on the Arduino circuit. The test results of welded joints show that the roughness is 0.20 μm which has the highest tensile strength.

Abstract

Welding is an important process in the manufacturing, metal and machinery industries, the welding results of students in the 1G Steel ST7 position are studied with the aim of identifying potential weld defects, determining root causes, evaluating and developing repair strategies to improve overall welding quality. The methods used in this research are qualitative and quantitative methods. Measuring welding dimensions with visual weld inspection, as well as liquid penetrant testing to identify weld defects. The data is processed using a Pareto diagram to determine the dominant types of defects that occur in the welding process. Once the dominant defect type is known, analysis is then carried out using the Fault Tree Analysis method. The results of the liquid penetrant test show that there are 8 types of weld defects with a total of 62 defects. In the FTA, basic events have been identified that contribute to the occurrence of weld defects, namely factors such as welding speed instability, incorrect current settings, and moist electrode. Regular evaluation, continuous monitoring and supervision during the welding process to reduce the risk of defects and improve welding quality
