In the past decade, the general method for measuring the performance of research and scientific publications in a Study Program at a Higher Education is by the Rough Value (Nilai Kasar, NK) calculated per three years. This value is derived from the accreditation instrument. In fact, the calculation of the performance of research and scientific publications with NK cannot represent an annual performance. Therefore, this paper presents a new method for calculating research and scientific publications performance with an index (IP-PS and IPub-PS), which is calculated annually. An example of quality measurement practice in the Automotive Diploma Program of Universitas Muhammadiyah Magelang. As a result, calculations with IP-PS and IPub-PS are more likely to present real conditions per year than using NK.

Abstract. This Community Partnership Program is in partnership with BINA USAHA Small and Medium Industries which is engaged in the metal welding industry. BINA USAHA also produces equipment and simple machines for industrial processing of agricultural products from surrounding communities, such as tobacco chopper machines and coffee peeler. The production equipment owned by the partners is still conventional. This condition causes low production capacity, in addition, the existing equipment is less ergonomic, so it often creates work inconvenience for employees. Apart from low production capacity, the use of conventional equipment will also result in poor product quality, because the uniformity of the dimensions of the workmanship cannot be maintained. Meanwhile, problems in the field of management, product marketing are still limited to certain areas. This is due to the lack of information received by partners in finding areas for product marketing, lack of marketing networks and the marketing area is not yet extensive. This activity uses a participatory community empowerment model / Participatory Rural Appraisal so that it requires active participation from partners. The solutions offered to solve the problems faced by partners in this PKM scheme community service activities are: a). Equipment development, b). Production process training, c). Develop a marketing model. The output target to be achieved from this activity is the application of science and technology ROLLS BENDING MACHINE at IKM BINA USAHA, so as to increase the competitiveness of IKM products and improve the welfare of the community.

In the next few decades, ethanol will take on the role of replacing fossil fuels. However, for direct application to the existing vehicles, an assessment of the corrosion resistance of the fuel tank is required. Therefore, this paper presents the results of corrosion resistance investigation of fuel tanks due to the application of ethanol. A Gravimetric method is used to test the corrosion. Ethanol is mixed with NaCl at various percentages as a corrosive medium. The test results show that the fuel tank has good resistance to corrosion due to ethanol use.

Gangguan kecil pada sistem pendingin akan menyebabkan overheating pada engine. Salah satu penyebab mesin overheating karena permukaan dalam sistem radiator pendinginan dipenuhi kerak. Melihat permasalahan di atas, korosi pada sistem pendinginan terutama dalam radiator perlu dikendalikan. Pengendalian korosi ada beberapa metode, diantaranya dengan perlakuan inhibitor. Penelitian ini bertujuan untu mengetahui mekanisme korosi, jenis korosi yang terjadi dan menentukan jenis inhibitor yang mampu menghasilkan laju korosi paling rendah. Alat untuk menguji komposisi kimia radiator dengan menggunakan spectrometer. Sedangkan untuk mengetahui jenis korosi radiator menggunakan microscop optic. Pengujian laju korosi menggunakan tiga sel elektroda didasarkan pada metode eskstrapolasi tafel. Hasil pengujian perlakuan inhibitor asam nitrat dari penambah berbagai metode menunjukkan hasil paling optimal pada penambahan inhibitor asam nitrat sebesar 5%. Hal ini dibuktikan dari penurunan laju korosi dari 0,002207 mmpy menjadi 0,00171 mmpy.

Datsun Go merupakan salah satu mobil Low Cost Gren Car (LCGC) yang beredar di Indonesuia. Mobil ini sudah dilengkapi dengan sistem AVG (Average) atau pembacaan rata-rata bahan bakar yang dapat dilihat dengan mudah pada display. Namun demikian laporan terkait konsumsi bahan bakar yang disampaikan pengguna kendaraan sangat bevariasi. Tujuan studi ini adalah untuk menginvestigasikesalahan pembacaan konsumsi bahan bakar pada berbagai kondisi dan dinamika kendaraan. Metode studi ini dengan mensimulasikan berbagai kemiringan dan juga akselerasi kendaraan. Hasil investigasi menunjukan bahwa terjadi kesalahan pembacaan fuel sender karena pengaruh dinamika kendaraan Dinamika dan kondisi kendaraan sangat berpengaruh terhadap pembacaan konsumsi rerata bahan bakar.

Magelang memiliki tingkat kemacetan yang cukup padat pada beberapa ruas jalan terutama yang menuju pusat kota, salah satunya pada simpang Armada Town Square Mall yang kian hari semakin padat. Oleh karena itu, artikel ini menyajikan analisis pemborosan bahan bakar akibat kemacetan dengan menggunakan citra google map. Dalam penelitian ini metode yang digunakan dengan melihat panjang kemacetan pada google map, kemudian menghitung jumlah dan jenis kendaraan yang terjebak dalam kemacetan. Hasil penelitian menunjukkan bahwa kerugian ekonomi akibat kemacetan lalu lintas di simpang Armada Town Square Mall Magelang dari arah Yogyakarta sebesar 147,13 liter per hari untuk gasoline dan 777,82 liter untuk solar. Estimasi kerugian ekonomi akibat kemacetan lalu lintas dalam rupiah sangat bervariatif menurut jenis bahan bakar yang digunakan. Kerugian minimal dalam satu hari adalah Rp. 4.950.000,- ketika menggunakan premium dan solar subsidi, sedangkan kerugian maksimum adalah Rp. 9.940.000,- ketika menggunakan pertamax turbo dan pertamina dex.

High Speed Steel (HSS) tool is commonly used in engineering applications, especially as cutters. The shortfall of this materials are wear and corrosion. However, these can be reduced by coating the surface of the material. Therefore, the purpose of this research is to investigate the effects of Diamond Like Carbon (DLC) coating, quenching heating treatment, and tempering on the physical and mechanical properties of HSS surface. The physical characteristics which will be investigated is the micro structure, while the mechanical characteristics are hardness, wear and corrosion rate. HSS has variations in their chemical composition (% mass): 0.75–1.5 C, Co >12, V > 5, 4–4.5 Cr,10–20 W and Mo. Furthermore, DLC coating uses Plasma Assisted Chemical Vapor Deposition (PACVD) technique with variation in the duration of coating (1,2,3,4,5 and 6 hours) at temperature of 300℃, with pressure variations of 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0 millibar. DLC coating material be treated from methane or ethane gas, which is streamed into the fire with Argon (Ar). The result shows variations in DLC coating and the hardness grade depends on the coating time and pressure variation. DLC coating for a duration of 4 hours under 1.8 mbar pressure can reduce the surface hardness of HSS tool by 62% accompanied by increased ductility.

This article is the result of implementing the CSR program of PT PLN Magelang Regency branch to help solve problems in the Rahayu Manunggal Women Farmers Group (KWT). High production costs and low profits are obstacles faced by KWT Rahayu Manunggal. This problem is caused by the production process of making brown sugar which uses quite a lot of energy, including the drying process of brown sugar. Applying an energy-efficient oven at KWT Rahayu Manunggal can help overcome this problem. The concept of the oven machine is designed by utilizing the heat/energy stored in the exhaust gas produced by the sap cooking furnace. The results obtained from this system can increase profits and reduce production costs, as well as improve the cleanliness of brown sugar processing.
