Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberdayakan masyarakat pra-sejahtera di kawasan Gandus, Palembang, melalui pelatihan dan sosialisasi pengecoran aluminium skrap sederhana sebagai upaya pemanfaatan limbah logam menjadi produk bernilai jual. Permasalahan yang dihadapi masyarakat setempat antara lain terbatasnya lapangan pekerjaan, rendahnya keterampilan teknis, serta belum optimalnya pemanfaatan limbah logam yang selama ini hanya dikumpulkan atau dijual dengan harga murah. Metode pelaksanaan kegiatan meliputi survei lapangan, pemberian materi teori, pembuatan tungku pengecoran sederhana, serta praktik langsung pengecoran aluminium skrap. Untuk mengukur efektivitas kegiatan, dilakukan pretest dan posttest terhadap peserta, yang menunjukkan peningkatan signifikan dalam pemahaman peserta terkait konsep dasar pengecoran, nilai ekonomis aluminium, dan keselamatan kerja. Hasil kuesioner juga menunjukkan bahwa 78,57% peserta menyatakan kegiatan ini sangat diperlukan dan materi yang disampaikan mudah dipahami. Dengan demikian, kegiatan ini memberikan kontribusi nyata dalam peningkatan keterampilan dan pemberdayaan masyarakat berbasis pemanfaatan limbah logam secara produktif.

Abstract

The utilization of red ginger, a rhizome rich in benefits, as a product with high market value can be achieved through the use of simple solar drying technology. However, there is still limited understanding of harnessing solar energy as a freely available drying source in nature. Community service activities aim to provide the basic theory of how to dry red ginger using solar energy, with the hope of enhancing community empowerment and contributing to economic self-reliance efforts. The target audience for this activity includes housewives, youth groups (Karang taruna), mosque youth associations, and local farmers in the MPD RT 02 Gandus Palembang area. The results of this activity show that the participants were highly enthusiastic in participating in discussions and Q&A sessions regarding the process of drying red ginger to create products with higher market value

Abstract

In the industrial world, leaf springs are an important component of vehicles. Therefore, material selection is very influential in producing good mechanical properties that can affect leaf spring performance. In this review article, the author aims to review and compile articles on relevant previous studies to compare the best alternative materials other than steel that meet the criteria for the application of leaf springs. The review method used in this article is to search for articles that are relevant to the keyword material, leaf springs, and mechanical properties. After that, the author will collect articles and choose articles that have the criteria to be reviewed. Then the articles that meet the criteria will be reviewed by extracting the data to the review table. As a result, 24 articles will be reviewed. Then the author will extract data on each article, namely material, tensile strength, and flexure. Flexural and tensile strength are used as quality criteria for each material. The conclusion of the review article obtained is that carbon/epoxy has the potential as an alternative steel material because carbon/epoxy has the highest tensile strength with a value of 1841MPa, and flexural strength with a value of 1646.7MPa is close to steel as shown in the review table. However, further research is needed, such as proper design and more efficient manufacturing methods to produce innovative leaf spring components with high quality and acceptable quality in the industry.

Abstract

Chloramphenicol is one of antibiotic compound which is an additional ingredient that is forbidden to be used in food products, especially in fresh shrimp product export. To avoid the used of preservative, then required sterilization process in a physical way which is vaporization using a high-pressure supercritical carbon dioxide (CO2). One of sterilization process for supercritical carbon dioxide is using autoclave media. Autoclave is a closed heating device used to sterilize or reducing a substance or object that is disserve by using high temperature and high pressure steam. In designing and constructing autoclave, the first step to be done is to define the function and the operation capacity. The function and capacity will determine the initial dimension of autoclave as well its working pressure and temperature. In this study, the autoclave was designed with quantitative methods and modeling using software Autodesk inventor 2016 based on finite element method. The given load is in the form of supercritical carbon dioxide pressure of 73.83bar and temperature of 31.30C. Based on the result of design, quantitative methods gives the safe result and optimized thickness needed autoclave usage.
