Abstract

Keuntungan proses permesin menggunakan CNC EDM adalah bisa membentuk bentuk yang kompleks yang biasanya sulit diproduksi dengan alat CNC konvensional. Salah satu hal yang menjadi kekurangan dalam proses permesinan dengan alat ini adalah waktu setting material. Dari sini perlu dilakukan sebuah improvement dalam mensetting benda kerja pada mesin CNC EDM. Saat ini yang terjadi di lapangan yaitu setting benda kerja dilakukan di mesin, dan ini menyebabkan produktifitas kerja mesin berkurang karena waktu setting yang membuang waktu. Salah satu cara untuk meminimalkan waktu yang terbuang adalah proses setting benda kerja dilakukan di luar mesin dimana benda kerja tidak disetting pada mesin CNC EDM. Beberapa metode telah diterapkan untuk menambah waktu proses machining dan menggurangi waktu setting benda kerja tetapi dirasa masih belum maksimal. Pada paper ini telah dirancang sebuah alat preset granit yang berfungsi sebagai alat setting benda kerja diluar mesin. Dengan adanya alat ini membuat ketika proses machining di mesin sedang berlangsung, para operator bisa mensetting benda kerja dan jika proses machining selesai benda kerja baru bisa langsung dipasang pada mesin CNC EDM. Sehingga menggurangi banyak waktu setting di mesin sehingga produksi menjadi lebih efisien.

Abstract

In the world of the plantation industry, to get a maximum harvest, the main factor that needs to be considered is the way of harvesting. An efficient, inexpensive, and effective harvesting process is the main thing that must be achieved. Indonesia as one of the world's palm oil-producing countries together with the Palm Oil Plantation Fund Management Agency (BPDPKS) continues to develop ways to optimize its palm oil production process. The harvesting process today still uses many manual methods using sickles and dodos. Some palm oil harvesting tools are already motorized, however, existing tools still have disadvantages in terms of price and vibration in the shaft. In this article, the author successfully applied the Quality Function Deployment (QFD) method and designed a motorized palm harvester where vibrations from the motor can be reduced by moving the motor's position using a Flexible shaft. Further modifying the gearbox from the material, gear shape, and some elements of the process engine makes the gearbox lightweight and have a small vibration. This study aims to make a motorized palm harvesting tool that can be used to harvest palm fruit quickly and easily. Another thing to aim for is to get a cheap motorized palm oil harvesting machine because all the parts are designed and produced independently and have low vibration. Experiments conducted at the Professional Services Cooperative (KJP) Cipta Prima Sejahtera Banjarmasin obtained a palm oil harvesting machine that had been designed to have a low vibration acceleration value, has easy maintenance, is lighter than existing motorized palm cutting tools, and the speed of cutting branches is many and fast compared to manual dodos cutting tools.

Abstract

PT Hexpharm Jaya Laboratories is one of the companies that is part of Kalbe Company which is specially engaged in the development, production, processing, and marketing of drugs. The process of processing medicinal raw materials at PT Hexpharm Jaya Laboratories uses several machines, one of which is the SMG (Super Mixer Granula) machine. This machine is used to mix medicinal raw materials and is the initial processing process before it becomes a granule. The problem that often arises in this machine is the problem of replacing bearings. Bearings attached to the shaft section connecting the gearbox with granules are often subject to damage that causes production stops/breakdowns. This unplanned maintenance process has previously been tried to be overcome by calculating the life of the bearing and alignment shaft connecting to reduce vibrations, but the bearing still suffers untimely damage. In this paper, a system was created to predict when the bearings need to be replaced by recording vibration data that occurs. The purpose of this study is to obtain a system that prevents unplanned maintenance so that it does not interfere with the production process Using the MPU-6050 sensor the vibrations on the bearings are measured and recorded during the machine's 12-hour operation. The results are obtained by a predictive maintenance system that can prevent breakdowns that result in the cessation of the production process. The system is created by recording vibrations that occur when the machine is working and is used as a way to predict the lifetime of the bearing. The system successfully measures the vibration value of the bearing and can be displayed, helping the maintenance technician estimate the exact time for bearing replacement in the SMG machine.

Abstract

Energi merupakan salah satu kebutuhan utama yang dibutuhkan oleh manusia. Di Indonesia ada beberapa jenis energi yang bisa dijadikan sumber energi salah satunya energi surya. Salah satu alat yang digunakan untuk pembangkit energi ini adalah Panel surya dengan sel surya sebagai pembangkitnya. Sel surya merupakan penghasil energi terbarukan yang merubah energi cahaya dan panas yang bersumber dari matahari dalam bentuk foton yang nanti akan menjadi energi listrik. Politeknik ATMI berkerja sama dengan PT. TRIMAS berkerjasama membuat suatu alat robot solar cleaner yang dipakai sebagai pembersih modul panel surya. Karena adanya alat pembersih tersebut maka kebutuhan akan suatu konstruksi rangka sebagai dudukan panelnya menjadi penting apalagi berat panel dan alat mencapai berat 64 kg. Dalam tulisan ini dirancanglah sebuah rangka panel surya yang mampu menahan bobot sampai dengan 64 kg. Dudukan panel surya yang dirancang juga bisa di bongkar pasang sehingga memudahkan mobilisasi tempat. Hasil desain juga di simulasikan bebannya menggunakan solid work. guna mengetahui pembagian beban pada rangka. Dari hasil simulasi didapatkan bahwa nilai tengangan maksimal yang muncul dengan beban 65 Kg didapat sebesar 5.37 Mpa. displacement yang terjadi sebesar 0.09 mm. Dari nilai yang didapat tersebut maka beban total 65 kg tidak menjadi masalah jika menggunakan konstruksi rangka berbahan alumunium pada didesain.

Abstract

The development of robotics technology today has developed rapidly. Many types of work that are done can be done with robots, especially if the work has a high level of accuracy. One of the jobs that require a high level of precision and accuracy is the work of cleaning the solar cell module. To get the maximum and continuous energy level from the sun, the cleanliness level of the solar cell module must always be maintained. Partial shading such as muddy and dusty results in a reduced level of electrical power generated. That's why it's important to keep solar panels clean. In this study, a solar cell module cleaning robot has been designed and tested directly in the field. The purpose of designing this robot is to ensure the cleanliness of the solar cell module from partial shading. The design created using two left-right drive motors is equipped with a brush motor for the cleaning system. Another addition is that this robot is controlled with a Wireless control system based on radio frequency (RF) communication and is equipped with sensors to determine the water level, as well as sensors that can keep the movement of the solar cleaner robot above the solar cell module when working.

Abstract

Press Machine For Switch Assy EPB module is an SPM (Special Purpose Machine) with a special function to carry out the pressing process of EPB (Electric Park Brake) products, namely an electronically controlled parking brake, where the driver activates the restraining mechanism with a button. So far, the epb product assembly process uses a manual mechanism by pressing the parts of the operator. This process is still not optimal, therefore it requires the development of a new EPB assembly system to improve and achieve maximum production processes. In this paper, an EPB product pressing system has been made using a jig. The jig is designed and manufactured using a photoelectric sensor integrated with the PLC. This study aims to improve the Quality Assurance of each EPB product and increase productivity to be more stable. The previous EPB product assembly process was carried out manually by the operator and there were often errors in the form of installation discrepancies in the process. In this paper, a press has been designed and made with sequential system operation with a ladder language program stored in a PLC. Sequential will run based on limit switches and photoelectric triggers to detect every product that enters the pressing process. The results of this study the quality and efficiency of the EPB assembly process increased where the human error that caused product failure was reduced, besides that the tools made had advantages among idle time in the EPB production process could be minimized.

Abstract

In this's era, the measuring instruments used in the machining process still use a lot of mechanical principles and there are only a few that are combined with electrical components. Most of the measuring instruments that exist now are only linear and there are still few that can measure the shape of the contour. One of the tools that can be used to measure contours is CMM, but the price of this tool is very expensive. The need for tools for this contour measurement process is very much needed in the industrial world because some parts of the industry have various contour shapes and are difficult if measured without using a CMM machine. Therefore, the purpose of this study is to make a measuring instrument for contour mapping using electronic sensors. The manufacture and design of measuring instruments start with designing electricity and hardware, then continues with microcontroller programming and Matlab. This measuring instrument is then tested for linear distance measurement accuracy, accuracy per angle, and accuracy of contour shapes. The results showed that the size results had a maximum deviation of 10 millimeters with a maximum distance of 500 millimeters. The 0° angle is the worst reading angle with a deviation of 8.67 millimeters, while the 90° and 180° angles are the best reading angles with a deviation of 1 millimeter. Square and rectangular shapes can be represented quite well, while triangular shapes are less well represented due to their angles being far from perpendicular to the sensor.
