Abstract

Tests for determining the elemental composition of stainless steel (SS) in the weld metal and Heat Affected Zone (HAZ) were carried out using the Non-Destructive Evaluation (NDE) Positive Material Identification (PMI) method with X-ray Fluorescence (XRF) technology. This study aimed to identify the chemical composition of metals using the PMI method with XRF technology as a determinant of the feasibility of the stainless-steel materials tested, namely SS 316 and SS 2205. The results of the tests were then matched with the applicable standards, namely ASME Section II Part A for pipe materials and ASME Section II Part C for welding electrodes. The measurement results show that SS 316 with welding electrode grade ER 316 all parts of the object of inspection fall within the standard range used except for material 4, which is the connection between the flange and elbow is declared rejected because the values ​​for Cr, Ni, and Mo do not fall within the standard range. Meanwhile, SS 2205 with a welding electrode grade of ER 2594 shows that all parts of the object being measured meet the requirements of the standard range used.

Abstract

Kemajuan teknologi menuntut industri manufaktur untuk dapat menghasilkan produk yang bentuknya lebih rumit dalam waktu lebih cepat. Teknik additive manufacturing atau percetakan tiga dimensi dapat mengatasi masalah ini, dengan mencairkan material kemudian dituang sedikit demi sedikit sebagai lapisan dalam proses pembuatannya. Produk yang dihasilkan memiliki permukaan yang kasar karena lapisan-lapisan yang dibentuk mesin cetak. Untuk menyesuaikan permukaan tersebut, dapat dilakukan pelapisan oleh cat emulsi. Studi ini meneliti kekasaran permukaan rata-rata (Ra) produk mesin cetak tiga dimensi dari bahan acrylonitrile butadiene styrene yang dilapisi cat tembok dan cat semprot dengan variasi waktu perendaman 5, 10, dan 15 menit. Hasil karakterisasi Ra oleh Surface Roughness Tester menunjukkan tingkat kekasaran permukaan sampel yang dilapisi selama 15 menit lebih rendah daripada 5 dan 10 menit. Nilai Ra sampel yang dilapisi cat semprot adalah 3,035 µm, lebih rendah daripada sampel terlapis cat tembok yaitu 2,650 µm untuk waktu perendaman yang sama yaitu 15 menit.

Abstract

Oil and gas companies are the largest users of steel pipes to produce oil and gas products from the mining, processing and distribution of ready-to-use oil and gas. Steel pipes used in the oil and gas industry can reach tens to thousands of kilometers with many welded joints every few meters. The possibility of corrosion on steel pipes is very large, so a corrosion-resistant coating is needed. Inconel material is often used as a coating material for the inside of steel pipes which is done by cladding welding. In this research, intergranular corrosion testing of the Inconel material layer as a result of cladding welding was carried out on steel pipes with filler metal UNS N06625 to determine the material's susceptibility to corrosion caused by the flow of oil and gas fluid in the pipe. The filler metals used were Ra***tna 625 and Nov***etal 625. Intergranular corrosion testing was carried out using ASTM G-28 standards. The results of the intergranular corrosion test showed that the cladding layer used filler metal for the Ra***tna 625 and Nov***etal 625 brands. No intergranular corrosion was observed, but there was uniform corrosion on the Ra***tna 625 brand with a corrosion rate of 0.46 mm/ year and 0.50 mm/year on the brand Nov***etal 625.

Abstract

The hydroponic pilot project in the Batam State Polytechnic area was motivated by problems with economic conditions and declining health conditions during the Covid-19 pandemic. This project is expected to support the “growing your own food movement” in an effort to reduce unemployment, increase food security and a healthy lifestyle. The hydroponic method was chosen because it is very easy to do and does not require a large area of ​​land. In this community service activity, a hydroponic plant building framework will be made as a prototype of an efficient and efficient hydroponic building so that it can be used by the wider community. This activity is also useful for applying design knowledge as one of the PbL activities carried out by CAD, CNC, CAM, and Fabrication Engineering courses in the Mechanical Engineering Department, so that it can become an arena for higher education participation to support people's lives. The method of implementing this community service activity is to make observations to find a suitable area to build a hydroponic plant house, then the results of the observations are poured in the form of a design by utilizing software so that the materials needed and the shape of the framework that is built can be known. The last activity is making a hydroponic plant place. This activity is planned to be carried out from April to November 2021. Based on the results of the evaluation of the service program questionnaire for product distribution, it is known that the majority of respondents are satisfied with the products produced.
