Abstract

The S690 and S235JR structural steels are widely used in heavy equipment for the main frame structure. In general, the fabrication processes of heavy equipment involve welding processes that could change the mechanical properties of the materials. Therefore, in the fabrication process involving those steels, a heat treatment process is carried out after welding to modify the mechanical properties. The heat treatment process is conducted mainly to eliminate residual stresses and to reduce brittleness through the annealing process. In this study, annealing was carried out on the two steels to observe the effect of the heat treatment process on the hardness and microstructure of the material. The annealing process was conducted at 760 oC, holding time varied at 2, 4, 6, 8 and 10 hours, and a cooling rate of 20 oC/hour. After the annealing process, observations with a metallurgical microscope were done to see the final microstructure, followed by testing material hardness using the Rockwell B method. The test results showed that the annealing holding time affected the phases and grain size as well as the hardness of the steel S690 and S235JR. The largest grain size is formed with a holding time of 10 hours while the lowest hardness is also obtained at a holding time of 10 hours. Annealing holding time also affects the phase change from fine bainite to ferrite with large grains on S690 and reduces the size of pearlite on S235JR. The test results also show that long holding time has the potential to cause a decarburization effect on steel.

Abstract

Polishing have played an important role in the preparation of metallography testing. Poor polishing produce in an unflat and rough surface of the material, resulting an unclear metallography image that is difficult to identified. In general, the material commonly used for polishing is alumina paste. Alumina paste is expensive and takes a few minutes to produce a smooth and flat surface. In this research, polishing was done by using several metal polisher other than alumina paste, these were magic***, auto***, bras**, ki*, menze*** and pri** which are sold cheaply at supermarkets or online stores. Analysis was carried out on the surface of the polishing by these materials and the etching surface. The test results showed that the material that is polished with magic *** has the smoothest surface or has the least residual scratches compared to other materials even compared to alumina paste, but has the disadvantage of corrosion forming on some parts of the surface. The best polishing time was obtained on polishing for 3 minutes

Abstract

Mold (cetakan) merupakan perkakas pada proses injection molding untuk membuat produk dari plastik. Akibat penggunaan selama proses produksinya, mold ini dapat mengalami kerusakan yang mengakibatkan terjadinya cacat pada produk. Penelitian ini dilakukan untuk mendapatkan informasi mengenai cacat produk yang sering terjadi akibat kerusakan pada mold serta bagian dari mold yang rusak pada proses plastic injection molding di perusahaan manufaktur Batam. Dari pengumpulan data yang dilakukan selama satu bulan, maka didapatkan bahwa cacat produk yang terjadi berkaitan dengan rusaknya mold adalah cacat flash (material sisa) dengan persentase sekitar 92% dan 8% colour streaks. Bagian mold yang mengalami kerusakan sehingga mengakibatkan cacat flash tersebut adalah sub insert (45,45%), insert (27,27%), slider (18,18%), dan ejector pin (9,09%). Oleh karena itu, dapat disimpulkan bahwa cacat produk yang sering terjadi akibat kerusakan mold adalah flash dan cacat flash banyak disebabkan oleh kerusakan mold pada bagian sub insert.

Abstract

Perbaikan dan perawatan kapal merupakan proses yang dilakukan pemilik kapal agar kondisi kapal yang diunakan selalu dalam kondisi prima. Masyarakat pesisir melakukan perbaikan kapal berdasar atas pengalaman yang biasanya diperoleh secara turun temurun. Dalam proses tersebut banyak masyarakat yang kurang peduli dengan resiko keselamatan dan kesehatan kerja. Hal ini bisa terjadi karena msyarakat sering berikir bahwa selama ini kegiatan tersebut tidak masalah sebab mereka tidak pernah sakit. Dengan kurang awamnya masyarakat terhadap masalah tersebut maka perlu diberikan sebuah penyuluhan serta langkah aman dalam melakukan perbaikan kapal yang pasti akan mereka lakukan.

Abstract

Personel Protective Equipment (PPE), as prevention to curb COVID-19 transmission which mainly via droplet, is a mandatory protocol as rising COVID-19 confirmed case. Face shield can protect face from droplet exposure. Besides health care professionals, pregnant women and newborn infants are susceptible population to exposure of SARS-CoV-2. Infant under two years is not recommended to use face mask due to breahing difficulty which can lead to mortality. Therefore, face shield is recommended for infant to give protection from virus transmission. As part of community service, Politeknik Negeri Batam produces Non Medical Infant Face Shield for infant and toddler to curb COVID-19 transmission. The program aims at community health centers (Puskesmas) of Batu Aji, Tanjung Uncang, Sekupang, and Kampong Jabi Nongsa. These partners value highly the community service program in terms of simplicity, clear working instruction, comfortability, recurring sterilization, and product quality. Moreover, high demand of face shield in Puskesmas that use face shield more than three times a day, indicates benefit of the community service in providing PPE for medical treatment at Puskesmas

Abstract

In this era of globalisation, many industrial companies have been built, especially in the chemical field. Chemical industry companies need a tank to store chemicals production result with a framework design that is nice and strong and can be moved easily. The material used is the type of carbon steel (S275JR) using the SMAW welding process at 6G welding position with intermediate currents in 59 A-134A. The type of joint for the frame is butt-joint, fillet joint and lap joint. In order to guarantee the quality of the welding results, the material will be tested in Non-Destructive Testing with the Inspection method using liquid penetrant, the penetrant method is solvent removable with visible sensitivity at a light level intensity of 1000 lux. The welding results are determined based on acceptance criteria in AWS with ASME as a critical reference. If there no defects or discontinuities like liniear and rounded were found in section of pad eye and base frame, then all welding results will be accepted.

Abstract

High residual stress can occur in stainless steel and carbon steel weld joints due to difference of thermal expansion coefficients. Corrosion-resistant and mechanical properties of weld joint is affected by stainless steel sensitization, resulted by chromium carbide precipitation, and carbon diffusion on heat-affected zone. This study is conducted to investigate post-weld heat treatment effects of stainless steel 316 and AISI 1018 weld joint with 309L filler metal. As the post-weld heat treatment temperature rises between 400 and 700°C, the hardness value decreases. Observed microstructure of heat-affected zone shows dominance of ferrite phase which experiencing grain growth.

Abstract

Power BI merupakan salah satu software intelligence buatan Microsoft yang digunakan untuk mengolah serta memvisualisasikan data dan menampilkannya dengan grafis yang lebih interakif serta variatif dalam bentuk dashboard. Beberapa keunggulan Power BI ini ialah bersifat Share Data, Real Time Dashboard, dan dapat mengolah data original yang jumlahnya melebihi kapasitas aplikasi lainnya. Dashboard pada Power BI akan digunakan untuk mengolah data Non-Conformance Material. Data Non-Conformance Material adalah data yang mencakup keseluruhan informasi dari kumpulan aktual material yang menyimpang dari standar atau ketentuan yang sudah ditetapkan dan dikategorikan ke dalam beberapa Defect Type. Material yang memiliki defect akan dikarantina untuk sementara waktu sampai mendapatkan disposisi yang telah disepakati pada saat Material Review Committee (MRC) Meeting. MRC Meeting merupakan pertemuan dari perwakilan masing-masing departemen untuk menentukan disposisi terhadap material Non-Conformance. Maka dari itu, penggunaan Power BI untuk representasikan data Non-Conformance Material sangat bermanfaat dikarenakan salah satu keunggulannya yaitu dashboard Power BI sendiri bersifat Live Data yang artinya ketika mengubah atau menambahkan sesuatu di Master File, dashboard Power BI akan berubah secara otomatis mengikuti Master File tersebut. Hal ini tentu saja dapat mempermudah visual yang tampak rumit bagi pengguna maupun audience yang melihat.
