Abstract

Kota Batam merupakan daerah dengan julukan kota industri. Sejak setelah bertranformasi menjadi kawasan industri kota Batam memiliki berbagai macam indutri yang dibangun, sehingga terbuka banyak peluang kerja yang tersedia. Salah satu keberlanjutan yang perlu didukung yaitu ketersediaan tenaga kerja terampil yang memiliki kompetensi dibidang keteknikan. Gambar dan penggunaan software CAD menjadi salah satu kompetensi yang perlu dipenuhi oleh masyarakat. Upaya menyediakan tenaga kerja terampil dapat dilihat dari tersedianya sekolah menengah kejuruan. Meskipun demikian, keterbatasan fasilitas praktik menjadi salah satu kendala yang dihadapi sebagian sekolah dalam melaksanakan layanan pendidikannya. Kegiatan Pelatihan Penggunaan Software AutoCAD kepada siswa/i SMK Kota Batam Tahun 2024 kemudian hadir menjadi salah satu solusi untuk dapat membantu sekolah dalam meningkat mutu pendidikan vokasi di Kota Batam. Pelatihan ini didanai secara internal oleh Politeknik Negeri Batam dan telah dilaksanakan di Politeknik Negeri Batam pada 23 – 26 Juli 2024. Adapun mitra peserta pengabdian ini adalah dari siswa dan guru SMK S Aljabar Batam, SMK S Kartini, SMK N 9 Batam. Beberapa luaran yang telah diselesaikan pada kegiatan pengabdian ini adalah terselenggaranya kegiatan dan penyusunan modul pelatihan. pemberitaan pada media masa, HKI modul, poster dan video kegiatan.

Abstract

A welding manipulator is a specialist apparatus engineered for welding extensive and elongated pipe plates on both interior and exterior surfaces, as well as in vertical and horizontal positions. During the assembly process, a challenge occurs when the platform is excessively distanced from the nozzle, complicating the operator's task with the welding manipulator. Brackets are an effective option to mitigate hazards and address issues throughout the cutting process. The aim of this research is to design and evaluate the safety of the bracket utilized for the platform component of the welding manipulator. The research utilizes Finite Element Analysis (FEA) to assess the simulated values of the safety factor and stress distribution. The findings demonstrate that the bracket design satisfies strength criteria, producing a maximum stress value of 98,327,504.00 N/m². The recorded maximum displacement is 1.094 mm, and the maximum strain is 0.00022. The computed safety factor is 2.1, indicating that the design parameters surpass established safety criteria.

Abstract

Block damage often occurs due to the pressing process and the presence of residual welding dirt on the slug so that a repair process is needed by means of grinding. If there is damage to the solid block, repairs are carried out on all sides of the block so that this is less effective and efficient in repair time. This research was conducted by changing the design of solid blocks into assembly blocks which aims to make the process of repairing blocks effective and efficient. To find out the results of the differences between solid blocks and assembly blocks, a trial was carried out by calculating the repair process time using a grinding machine with a depth of 0.04 mm. The results of the solid block repair process trials obtained an average of 397 seconds while the assembly blocks obtained an average of 248 seconds. Thus cutting the repair process time by 149 seconds. With this design change, the effectiveness and efficiency of block repair time is obtained.

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.

Abstract

This community service initiative aims to enhance the skills of vocational school students in utilizing Laser cutting machines, serving as a platform for students in the Design and Visual Communication department of SMKN 9 Batam to fabricate products based on their own designs in preparation for the professional world. The participants involved in this initiative consist of 78 students from the aforementioned department. The community service program is structured through various stages, encompassing initiation, preparation, execution, activity review, and the compilation of a final report. Enthusiastically engaged, the participants, primarily from the Design and Visual Communication department, had previously focused their learning solely on the design phase. However, through this community service project, they actively participated in the fabrication process of designs they had created. Utilizing CAD applications, the designs were transformed into tangible products using acrylic as the raw material, ensuring that the resulting products align with the envisioned design. This initiative provides a valuable avenue for students to bridge the gap between design and fabrication, fostering practical skills crucial for their future endeavors in the workforce.
