Abstract

There are still many people who do not know and understand the COVID-19 virus, which is still new. Some of the news that can be accessed on news search links show a lot of oppression and stigma against people called COVID-19. Stigma, among other things, arises because society ignores new diseases and there is no cure, stigma can be suppressed and lost if society finds out about it. Generally, service activities are conducted to provide knowledge and understanding of COVID-19 and how to prevent it. Stigma prevention is done by environmental disinfection activities, mask distribution for adults and children as well as counseling on clean and healthy living habits and physical distance, disinfection activities and mask distribution done to give a sense of peace to the population. Clean and healthy lifestyle guidance activities and physical distance are done to provide correct information. Generally, service activities are conducted to provide knowledge and understanding of COVID-19 and how to prevent it. With the right knowledge, stigma will not occur in society. This service can improve people's knowledge and understanding of COVID-19, live a new life pattern, and understand the attitudes and views that should be present when dealing with people called COVID-19 so that people can live their daily lives calmly and vigilantly

Abstract

Plastik merupakan salah satu jenis sampah yang volumenya semakin meningkat dari tahun ke tahun. Seiring dengan perkembangan ekonomi, penggunaan plastik semakin meningkat. Hal ini dikarenakan oleh keunggulan plastik dibanding dengan jenis material yang lain seperti ringan, kuat, tahan korosi, sifat insulasi yang baik dan mudah diwarnai. Karakteristik sampah plastik yang berbeda dengan sampah organik adalah sulitnya terurai di dalam tanah, diperlukan waktu puluhan atau ratusan tahun agar dapat terdegradasi sempurna. Oleh karena itu, penanganan sampah plastik dengan sistem landfill maupun open dumping bukan merupakan pilihan yang tepat.  Seiring perkembangan jaman, banyak hal yang dilakukan untuk mengurai sampah plastik khususnya adalah botol plastik, di antaranya adalah mendaur ulang kembali sampah botol plastik tersebut dengan cara dihancurkan terlebih dahulu. Penghancuran limbah plastik diharapkan dapat mengurangi limbah botol plastik menjadi hal yang buruk bagi lingkungan dan juga meminimalisir adanya pemalsuan botol plastik sehingga dapat melindungi hak konsumen sebagai pengguna sehari hari seperti botol oli, botol air mineral dan botol botol plastik ringan lainya. Kelurahan Menteng Jakarta Pusat memiliki bank sampah, namun pengelolaan sampah khususnya sampah plastik dalam bentuk botol belum optimal. Metode yang digunakan dalam pelaksanaan pengabdian ini adalah pelatihan pengenalan mengenai sistem kerja mesin crusher botol plastik dan pemberian hibah mesin tersebut kepada warga Menteng Jakarta Pusat. Hasil kegiatan pengabdian ini dapat membantu industri kecil dan rumah tangga dalam membuka peluang bisnis dari hasil daur ulang botol plastik bekas.Kata Kunci : pelatihan, hibah mesin, mesin crusher, botol plastik

Abstract

One of the basic competencies that Vocational High School (SMK) mechanical engineering teachers must have is being able to draw technically using CAD (Computer Aided Design) based applications. This competency is part of the competency field of study expertise that teachers must have. From the results of observations in the field, it was found that there are still many vocational school teachers in Cilegon City who are still not experts in using CAD-based applications, one of which is SMKS YP Fatahillah 1 Cilegon. As a form of implementation of one of the duties and obligations of the Tri Dharma of Higher Education, the Mechanical Engineering Department of Sultan Ageng Tirtayasa University carries out a community service program, namely training in the use of CAD-based technical drawing applications at SMKS YP Fatahillah 1 Cilegon. This activity was carried out for 3 days and was attended by 24 participants who work as teachers and laboratory assistants at the vocational school. The training method is delivered by lectures, presentations and direct exercises and practice. From this activity, the results showed that there was an increase in the competency of the participants, namely in their ability to draw techniques.

Abstract

Laminated composites are composed of multiple layers that work together to achieve specific properties. Several factors influence the strength of these composites, including the quality of the surface layers, the strength of the bonds between layers, the adhesion properties, and the thermal behavior. The adhesive plays a crucial role in connecting the layers to form a laminated composite. This study investigates the effect of environmental exposure on the bond strength between the surfaces of laminated composite layers. The laminated composites are made from mahogany wood and are adhered using PVAc adhesive under a pressure of 2 MPa for 30 minutes. After being prepared, the samples are allowed to sit for several days before being immersed in distilled water, seawater, and vegetable oil. Each immersion lasts for 24 hours. The results indicate that the laminated composites experienced a degradation of mechanical properties following exposure to distilled water, seawater, and vegetable oil. Among these, distilled water had the most detrimental effect on the performance of the laminated composite, while exposure to vegetable oil resulted in relatively insignificant changes to its mechanical properties.

Abstract

The abundant amount of plastic waste and the high environmental problems it caused encourage the efforts to utilize recycled plastic materials in various applications, including the manufacture of plastic block produced using injection molding. This study aimed to analyze the effect of a mixture of recycled plastic types (PP, HDPE, and LDPE) on the mechanical properties of plastic blocks. Two of the three types of recycled plastic used were combined with a 1:1 composition and then molded into plastic blocks. Testing was carried out through tensile tests and impact tests to assess the tensile strength and toughness of the material. The results showed that the PP + HDPE alloy produced a tensile stress value of 26.2 MPa, a strain of 29.2%, and an elastic modulus of 89.6 MPa. While the average impact test value of this alloy reached 0.168 Joules/mm² with a maximum bending load of 3.94 kgf/cm². This alloy can be used as a reference material for manufacturing plastic blocks that have good mechanical properties.

Abstract

The exploration of natural resources as materials for engineering applications is increasingly important, as organic materials offer greater environmental benefits. The Maja fruit, a typical Indonesian plant, has not been fully utilized for engineering purposes, particularly its shells. The goal of utilizing this material is to contribute to sustainable development. In this study, Maja fruit particles were used as a filler in combination with rice husk ash. The particle compositions of Maja fruit were set at 20%, 30%, and 40%, respectively. The composite fabrication process was conducted under cold conditions at a pressure of 30 MPa. The results indicated that an increase in the composition of Maja fruit shell particles led to higher compressive strength in the composite, although this caused a decrease in surface hardness. The optimal composite performance was achieved with a composition of 40% Maja fruit shell particles and 60% epoxy resin, as determined by a weighting method. It was also observed that while the inclusion of rice husk ash tended to reduce compressive strength, it contributed to enhancing the hardness of the composite.

Abstract

Sugarcane bagasse and oil palm Empty Fruit Bunches (EFB) are abundant agricultural by-products in Indonesia that, if unmanaged, pose significant environmental risks. This research investigates their potential as sustainable raw materials for composite acoustic boards. Composites were fabricated using hybrid fibers consisting of 67% bagasse and 3% EFB, bonded with a matrix of Polyvinyl Acetate (PVAc) and varying ratios of epoxy resin (0%, 1%, 2%, and 4%). Boards were cold-pressed at 20 MPa for 30 minutes and air-dried for 7 days. The incorporation of epoxy resin significantly improved physical integrity and acoustic performance. Sound Absorption Coefficients (SAC) increased from 0.37 (0% epoxy) to 0.67 (4% epoxy), indicating enhanced absorption in mid-to-high frequency ranges. These results support the feasibility of utilizing agricultural waste for sustainable engineering applications, thereby contributing to the development of eco-friendly materials.

Abstract

Machines in manufacturing areas often cause noise. The noise comes from machine tools such as lathes, milling machines, grinder machines, and other tools that cause sound and vibration so they are prone to causing physical and psychological disorders. This study was to determine and analyze the noise level in three areas and ten points in the manufacturing room of The Job Training and Development Center Serang by the Regulation of the Minister of Manpower and Transmigration of the Republic of Indonesia Number PER.13/MEN/X/2011 with the maximum noise limit that has been set is 85 dBA. As for the results of the ten points, there is a point that exceeds the threshold value, namely at point 6 (85.8) dBA in the lathe area. Every operator in the manufacturing room that has a noise level that exceeds the threshold value must wear personal protective equipment in the form of earplugs or ear muffs that have been provided by the workshop to reduce the noise level.

Abstract

Adhesive bonding is a technique widely used in various industries to join materials together. This process provides several advantages over traditional mechanical fastening methods, such as welding or nailing, including improved appearance, weight reduction, stress distribution, and the ability to join dissimilar materials. The advantages of adhesive bonding are simpler assembly, lightweight and lower production costs. This research is one of the developments of the glue adhesive connection method. The materials used in this research are 1100 series aluminium and low carbon steel where both are metals that we often encounter in everyday life. This study aims to analyse the effect of roughness treatment on the surface of each different test specimen using sandpaper with different roughness levels, namely 80 grit, 150 grit and 400 grit. The test conducted in this study was a tensile test to determine the maximum strength of the adhesive strength of each test specimen with ASTM D1002 test standards. The results showed that test specimen A with surface roughness treatment using 80 grit had a tensile strength of 0.2267, test specimen B with surface roughness treatment using 150 grit had a tensile strength of 0.168 and test specimen with 400 grit roughness treatment had a tensile strength of 0.0315.
