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.

Abstract

Penelitian ini dilakukan berdasarkan hasil survei dan investigasi pada industri elektronik yang berlokasi di Bintan. Perusahaan tersebut bergerak pada bidang Design and Manufacture of Precision Engineering Plastic Components and Electronic Connectors. Dari hasil konsolidasi diperoleh bahwa salah satu aktivitas yang dilakukan yaitu melakukan proses maintenance dengan cara melakukan penggantian suku cadang Molding yang digunakan untuk menghasilkan komponen plastik maupun elektronik. Pada aktivitas produksi, suku cadang Molding tersebut secara prosedur pasti dilakukan pergantian setiap jumlah produksi tertentu atau bisa diperkirakan setiap bulannya terjadi pergantian suku cadang. Oleh karenanya menjaga kesediaan suku cadang menjadi hal yang urgen demi terlaksananya proses produksi dan terpenuhi target perusahaan. Suku cadang yang dimaksud selama ini dipesan dan dibuat dari negara Singapura sehingga perputaran, proses transfer maupun kajian teknologi tidak termanfaatkan oleh industri di Indonesia. Padahal nilai suku cadang yang diganti setiap bulannya sangat besar dengan perkiraan secara kasar memiliki nilai total milyaran rupiah. Berdasarkan hal tersebut diperlukan kajian yang berfokus untuk mendalami proses pembuatan suku cadang dari Molding sehingga industri tidak perlu mengimpor suku cadang dari negara luar.

Abstract

This research explores the issue of distortion in spool pipes within the context of the fabrication process, with a specific focus on pipe connections with flanges. The main objective of this study is to investigate the impact of distortion caused by the tacking process during fit-up and the sequence of welding sequences in the welding process. The experiments were conducted by collecting data through inspections of concentricity in the connections using the Total Station Sokkia CX 101 S/N GP1159 tool, with tolerances set at 1, and 0.75 for capping weld. Fabrication Piping and Structure Onshore served as the testing location, with ASTM A671 CC60-12 as the testing material. All tests were conducted at room temperature. The inspection results were used as a guide for the repair process, providing instructions to the Fitter for improving the connections and enabling the welder to maintain the precision of the pipe connections with flanges to avoid distortion. Based on the experimental results, the concentricity of pipe connections reflects the occurring distortion, while welding sequences show a counter effect at each welding step. The distortion after welding, measured at 0.75, still complies with client specifications.

Abstract

ABSTRACT – This study aims to compare the effects of Constant Cutting Speed (G96) and Constant Spindle Speed (G97) modes on the surface roughness of ST 37 and S45C materials in step-turning processes using a CNC lathe. A comparative experimental method was employed, measuring surface roughness (( R_a )) at stepped diameters (16 mm, 24 mm, 32 mm, and 35 mm) with a Mitutoyo Surface Tester SJ-210. Results indicate that G96 mode produces lower surface roughness, with average ( R_a ) values of 2.22 µm (S45C) and 2.27 µm (ST 37) in the N6 class, compared to G97 mode with ( R_a ) values of 3.08 µm (S45C) and 3.03 µm (ST 37) in the N7 class. G96 mode is superior due to its ability to automatically adjust rotational speed based on diameter, whereas in G97 mode, small diameters with high rotation (1273 rpm) increase roughness due to vibration or heat. This study recommends using G96 mode for optimal surface smoothness in step-turning of similar materials. rning of similar materials.
