Abstract

The current condition of the COVID-19 pandemic has made the economy mostly experience a setback, also experienced by partners, namely the Mulyadi family in Padang Buan, Medan City, not far from the Medan State Polytechnic. Mulayadi, who owns a grocery business selling basic necessities, was forced to close the business because of the declining number of buyers, including due to competition between the same businesses. Next the partners think what to do then turn around and start the table carpenter business. With conventional tools such as hand planers, hand saws, manual chisels and manual painting, partners make wooden tables, and sell them quickly to coffee shops in Padang Bulan around USU. With the help of his son, he tried to offer his wooden table through social media and it turned out that there was a request from the community. As demand from buyers increases, partners find it difficult to meet buyers and are constrained by increasing their business in making wooden tables because they require modern equipment such as electric planers, electric saws, electric drills, compressors, and painting gun units, and partners do not have the money to buy tools. the tool. This was conveyed to the Polmed lecturer to ask for help providing these tools. Then the implementation team carries out a survey, evaluating needs that can improve the work of partners, so that the implementation team of this service aims to help provide carpentry tools and provide training on the use of tools properly and safely. Then the service implementation team made a submission to Polmed through P3M and carried out a service program by handing over tools or machines in the form of 2 electric planers, 1 electric saw, 1 electric drill, compressor and painting gun unit. At the time of delivery, partners said that with manual equipment made of wooden tables as many as 1-2 tables per week, then with the availability of tools provided by Polmed through the chief executive, they could make 4-5 tables per week with more aesthetic ones, and therefore partners' opinions became increase.

Abstract

The Department of Mechanical Engineering of the Medan State Polytechnic (POLMED) has international standard welding practice and laboratory equipment. In line with the progress of this equipment, quite a number of teaching staff in this study program already have teaching certificates in the field of welding. The socialization of welding in this study program has received recognition from the Professional Institute International Welding (IIW) and The Welding Institute (TWI), so that the Mechanical Engineering Department has become a Competency Test Site (TUK) for IIW and TWI international certification. The proponent of this international standard welding defect recognition training program already has a CSWIP (Certificate Scheme Welding Inspection Personnel) 3.0 certificate from The Welding Institute. LPK IMMANUEL MEDAN has a Welding course training field, this is related to making vehicle frames (chassis body). Participants who take part in this program have good achievements and are prepared to enter the world of work after being declared graduated with proof of a certificate. It is very reasonable for LPK IMMANUEL MEDAN to accept the offer of an international standard welding defect identification training program held by a lecturer from the Department of Mechanical Engineering, Medan State Polytechnic (POLMED). especially to hold welding inspection socialization based on TWI standards. This knowledge will prepare prospective LPK Immanuel graduates to enter jobs in the welding field. This program is very relevant to the adult world of work. With this training, LPK participants will gain insight into how welding results meet the TWI standard, which is a standard that is widely used in the international world. This is supported by experienced and certified lecturers who carry out the service above in the CSWIP 3.0 (welding inspector) training in the use of the welding gauge which will be donated to the LPK Immanuel. Through this program, welding inspection modules and welding gauges have also been donated so that LPK participants can use them in the future

Abstract

Kegiatan ini bertujuan untuk merancang dan membuat mesin pencampur (mixer) pakan ternak domba yang akan difermentasi bagi peternak domba di Dusun VI, Desa Sei Glugur, Kecamatan Pancur Batu Kabupaten Deli Serdang, Provinsi Sumatera Utara. Kegiatan diawali dengan melakukan observasi di Dusun VI, Desa Sei Glugur, Kecamatan Pancur Batu Kabupaten Deli Serdang yang dituju. Observasi ini bertujuan untuk mendapatkan gambaran atau kendala yang dihadapi oleh peternak. Dari hasil observasi kemudian dilakukan rekayasa perancangan mesin sesuai kebutuhan. Sebagai salah satu alternatif untuk meningkatkan produktifitas dan efisiensi dalam usaha pembuatan pakan ternak fermentasi untuk domba khususnya untuk proses pencampuran bahan baku, maka direncanakan untuk rancang bangun mesin pencampur bahan-bahan baku pakan ternak kapasitas 300kg/jam. Dengan harapan dapat membantu usaha pembuatan pakan ternak untuk memberikan solusi dalam memaksimalkan pencampuran pakan ternak dengan kapasitas yang lebih banyak dengan waktu yang lebih singkat.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh variasi fraksi volume serat daun nanas (10%, 20%, 30%, 40%, dan 50%) terhadap sifat tarik komposit berbasis resin epoksi. Serat daun nanas terlebih dahulu diberi perlakuan alkali menggunakan larutan NaOH 5% untuk meningkatkan kekasaran permukaan dan adhesi dengan matriks. Proses pembuatan spesimen dilakukan dengan metode hand lay-up, dan pengujian tarik mengacu pada standar ASTM D638. Hasil penelitian menunjukkan bahwa peningkatan fraksi volume serat hingga 30% menghasilkan kekuatan tarik maksimum sebesar 49,3 MPa. Nilai modulus Young juga meningkat hingga fraksi tersebut, kemudian menurun pada komposisi serat yang lebih tinggi akibat terbentuknya void dan aglomerasi serat.
