Abstract

Telah dilakukan penelitian mengenai analisis perpindahan panas pada water jacket di ruang bakar primer incinerator sampah kota. Analisis perpindahan panas dilakukan ketika water jacket berada dari fase cair hingga mencapai titik didihnya, yaitu 100 oC, Suhu api pembakaran diasumsikan seragam berdasarkan hasil pengukuran api ruang bakar diperoleh nilai stabil yakni 1097 oC. Variasi debit aliran water jacket adalah 300, 400, 500, dan 600 liter/jam. Tujuan penelitian ini adalah untuk mengetahui bagaimana kenaikan suhu dan karakteristik perpindahan panas pada water jacket dan pengaruh variasi debit terhadap kenaikan suhu water jacket  di sepanjang ketinggian dinding ruang bakar. Penelitian dilakukan dengan melakukan perhitungan parameter termohidrolika yang merupakan fungsi suhu yang meliputi densitas, viskositas, konduktivitas, dan bilangan Prandtl. Kemudian, dilanjutkan dengan melakukan perhitungan bilangan Reynolds, Nusselt, koefisien perpindahan panas konveksi, Log Mean Temperature Difference (LMTD), resistensi termal total, dan laju perpindahan panas di sepanjang tinggi cerobong (L) sampai suhu air mencapai 100 oC. Perhitungan tersebut dilakukan dengan metode Euler. Dari hasil perhitungan perpindahan panas diketahui bahwa suhu water jacket di sepanjang ketinggian dinding ruang bakar mengalami kenaikan hingga mencapai titik didihnya. Akan tetapi, ketika aliran water jacket semakin mencapai ke atas, gradien kenaikan suhunya mengalami penurunan nilai. Dengan demikian, laju perpindahan panasnya juga ikut mengalami penurunan. Dari variasi debit diperoleh hasil bahwa semakin besar debit aliran water jacket, kenaikan suhu yang dialami water jacket di sepanjang ketinggian ruang bakar juga semakin kecil. Dengan demikian semakin besar debit aliran water jacket, lintasan yang dibutuhkan untuk mencapai titik didihnya juga semakin panjang. Semakin besar debit aliran water jacket, maka laju perpindahan panas di posisi aliran yang sama juga semakin besar.

Abstract

Motorized vehicles, especially motorbikes, have now become daily necessities, no longer classified as luxury goods. Due to the high level of need, almost every family has one motorbike, maybe even more than one. Motor vehicles are simple forms of transportation, can be driven in residential areas, both urban and rural, and the operational costs are relatively affordable for most groups. Current developments in motorbike design allow riders from young to old. Data shows that demand and use of motorbikes continues to increase. According to the Central Statistics Agency (BPS), in 2022 the number of vehicles in Indonesia will reach 148,212,865. The number of private vehicles in Indonesia is still dominated by motorbikes with a figure of 125,267,349 units (almost 85% of which are dominated by motorbikes). With the rapid increase in the number of motorized vehicles, many workshops and repairs have emerged, both large and small, official and unofficial workshops. The problems that arise are due to busyness, laziness or lack of knowledge and skills, so motorbike servicing is carried out at a repair shop. Especially for young people and students, who only like riding motorbikes, don't care about the condition of the motorbike, and don't learn how to service it even to repair minor damage. This will benefit the workshop. In fact, you should be able to save money if you can repair it yourself. It can even be detrimental if it is serviced by an irresponsible illegal workshop. From the results of surveys and observations at the Assa'adah Islamic Boarding School, South Tangerang, almost all students are unable to service their motorbikes themselves. Therefore, the team of Mechanical Engineering Lecturers at Pamulang University offers motorbike service training for students with the aim of giving them knowledge and skills in servicing motorbikes. Armed with this knowledge and skills, it is hoped that motorbike maintenance and if damage occurs, you can do it yourself, you don't need to take it to a repair shop. At least with this knowledge and skills, you can save financial expenses, and even the knowledge and skills obtained can become provisions for opening a motorbike service business in the future. The training offered is packaged in the form of Community Service (PKM) as one of the elements of the Tridharma of Higher Education. A short training method will be given in theory about motorbike service and maintenance, and practical motorbike service and maintenance will be carried out.

Abstract

Measurement is the process of comparing parameters on a being measured object against standardized one. It is an effort to obtain descriptive-quantitative information about the physical and chemical variables of a substance or object being measured, such as a length of 1 meter or a mass of 1 kilogram, and so forth. In everyday life, many objects require measurement for specific purposes in the workplace, at schools or campuses. Based on observations carried out at Assa’adah Islamic High School in Puri Serpong, South Tangerang, there are constraints related to measurement subjects such as lack of teaching competence, laboratories and practical equipment. Therefore, technical measurement training is needed for students at Assa’adah Islamic High School in Puri Serpong, South Tangerang, to enhance their knowledge and develop good skills in measuring technical equipment. The process of learning technical measurement at the high school should be supported by various factors, including student motivation, learning media, learning facilities, teacher motivation, and the teaching methods used by teachers. The result of the after training is that the knowledge and skills of the students related to technical measurement, increasing than before.

Abstract

Choosing a good machine and process to make a particular product requires basic knowledge about all the possibilities that occur during the production process. Therefore, material selection, machine settings and determining appropriate machining parameters need to be optimized to produce quality products. In the milling process, surface roughness is very important. From this surface roughness, an evaluation can be made whether the workpiece is acceptabel or not. The lower the surface roughness of a workpiece, the better the quality of the workpiece. The higher the surface roughness, the lower the performance of the components of the workpiece pair will be because it will increase friction on the components of the machine elements. This research aims to determine the effect of variations in feeding work movement, spindle rotation, and feed depth on the level of surface roughness resulting from conventional milling machining processes. This research also discusses which influences produce optimal surface roughness values in conventional milling machining processes. This research was carried out three times in one combination. Data collection on surface roughness values was carried out horizontally on the surface of the workpiece by taking data three times on the workpiece. The results of the statistical analysis prove that the feeding movement variable is proven to have a significant influence on surface roughness, while the optimum combination for the lowest level of surface roughness can be obtained with a feeding movement of 249 mm/minute (3rd test)

Abstract

Indonesia's natural and cultural riches have attracted the attention of foreign researchers to conduct research in Indonesia. Indonesia is considered to be one of the largest biological laboratories in the world, so there are many objects that can be used for research by foreign researchers. To provide research licensing services for foreign researchers who wish to conduct research in Indonesia, a legal basis was issued, namely Law No. 11 of 2019 concerning the National System of Science and Technology which regulates research licensing for foreign researchers in Indonesia. As a supporter of Law no. 11 of 2019, BRIN Regulation no. 22 of 2022 concerning Ethical Clearance has been issued. To provide foreign research licensing services according to Law No. 11 of 2019, it is carried out by the Directorate of Research and Innovation Licensing and Scientific Governance of the National Research and Innovation Agency (BRIN). To make it easier to apply for research permits for foreign researchers, several service improvements were made, namely the first was the formation of an ethics commission team to replace the TKPIPA team to evaluate incoming proposals. Second, the number of files that foreign researchers need to prepare is less than before, namely from 14 documents to 7 documents. Third, creating an ethical clearance website to upload the required files in digital form which was previously done offline and submitting hard copy files. Fourth, the addition of financial reporting features to make it easier to check payments and send research progress reports by foreign researchers.
