Abstract

Postur kerja yang tidak sesuai bisa menjadi pemicu timbulnya keluhan fisik pada pekerja, terutama jika dilakukan dalam waktu lama dan berulang. Penelitian ini bertujuan untuk menganalisis postur kerja operator dalam proses penggerindaan ulir pada pipa OCTG dengan menggunakan metode Rapid Entire Body Assessment (REBA), serta perbaikan ergonomi yang dibutuhkan untuk mengurangi potensi risiko. Penilaian dilakukan menggunakan metode REBA dengan pendekatan deskriptif semi-kuantitatif. Data diperoleh dari observasi langsung di lapangan, dokumentasi foto, pengukuran sudut tubuh menggunakan AutoCAD, dan wawancara dengan dua orang operator. Hasil awal menunjukkan bahwa posisi kerja operator termasuk dalam kategori risiko sedang, dengan skor REBA sebesar 7. Untuk mengurangi risiko tersebut, dudukan gerinda dibuat yang disesuaikan dengan tinggi badan operator. Setelah perbaikan dilakukan, skor REBA menurun menjadi 2, yang menunjukkan risiko rendah. Perubahan terlihat jelas terutama pada posisi punggung, leher, dan kaki yang menjadi lebih tegak dan seimbang. Hasil ini menunjukkan bahwa perbaikan sederhana yang memperhatikan kenyamanan postur kerja dapat berdampak besar terhadap kesehatan dan kenyamanan pekerja, serta membantu menciptakan lingkungan kerja yang lebih baik.

Abstract

Portable open waste container is a traditional waste transport tool that is still widely used in various places. Skid frame is an important component in the construction of portable open waste container that serves to withstand static and dynamic loads during waste transport. Therefore, it is necessary to analyse the strength of the skid frame structure to ensure the design is able to withstand the given load. This research aims to analyse the stress distribution, deformation, and safety factor of the portable open waste container skid frame using the Finite Element Analysis method in Solidworks software. The analysis results show that the maximum stress that occurs in the skid frame is 249.921 MPa which almost reaches the yield stress of ASTM A36 steel material, which is 250 MPa, with a maximum deformation of 20.544 mm, and a minimum safety factor of 0.6. Based on these results, it can be concluded that the skid frame design needs to be optimised to improve the durability of the structure and safety during operation

Abstract

Halal products are products that are starting to be looked at by the market today. One of the goals of the Indonesian government, under BPJPH, in 2024 it is hoped that products, especially food and beverages in Indonesia, will already have halal certificates so that they can increase the attractiveness of pariwasata for Muslims around the world if they visit Indonesia. Based on the new legislation in 2014, namely law no. 33 of 2014 concerning Halal Product Guarantee, the halal certification process is carried out in synergy by various parties, one of which is the halal product guarantee organizing body (BPJPH). Halal product process assistance is a process of verifying and validating halal statements by business actors (self-declare). This activity serves to assist micro and small business actors in meeting product halal requirements. The purpose of this community service is to find out the level of understanding of prospective halal product process assistants in Batam City, service activities are carried out with 3 stages, namely surveys, socialization and training activities and the last stage is evaluation and reports. This activity is supported by BPJPH and Bank Indonesia as additional sponsors for activities to be carried out offline and online.

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

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.

Abstract

Persediaan air bersih bagi kehidupan sehari-hari masih menjadi permasalahan dalam ruang lingkup kesehatan lingkungan karena kualitasnya harus sesuai dengan syarat kesehatan terutama kandungan zat besi (fe) pada air bersih. Tujuan penelitian untuk mengetahui kadar besi (Fe) pada air sumur gali dan efektifitas metode kombinasi pembubuhan kaporit dan filtrasi arang aktif dalam menurunkan kadar besi (Fe) pada air sumur gali Lingkungan RT.03/RW.01 Kelurahan Tanjung Ayun Sakti Kota Tanjungpinang Tahun 2019. Metode penelitian yang digunakan adalah penelitian eksperimen. Rancangan penelitian yang digunakan adalah one group pretest-posttest (pretest-posttest design). Populasi dalam penelitian ini adalah air sumur gali masyarakat di wilayah RT.03/RW.01 Kelurahan Tanjung Ayun Sakti Kota Tanjungpinang dengan sampel sebanyak 3 sumur. Hasil penelitian menunjukkan bahwa kualitas air sumur gali sebelum pengolahan memiliki kadar zat besi (fe) dalam air yang tinggi mencapai 80,81mg/l–891.49mg/l dan setelah pengolahan dengan metode kombinasi bubuhan kaporit dan filtrasi arang aktif, kadar zat besi (fe) menurun menjadi 0.026mg/l– 0.040mg/l. Hal ini dapat disimpulkan bahwa pengolahan air menggunakan metode kombinasi bubuhan kaporit dan filtrasi arang aktif mampu menurunkan kadar zat besi (fe) dalam air sumur dengan nilai keefektifitasan mencapai 99,99%. Pengolahan air sumur dengan metode bubuhan kaporit dan filtrasi arang aktif ini dapat diterapkan di masyarakat karena dengan biaya yang sangat terjangkau masyarakat telah mendapatkan kualitas air bersih yang dapat digunakan untuk keperluan sehari-hari.
