This study discusses the numerical study of two-dimensional analysis of flow through circular cylinders. The original physical information entered in the equation governing most of the modeling is transferred into a numerical solution. Fluid flow on two-dimensional circular cylinder wall using high Reynolds k-ε modeling (Re = 106), Here we will do 3 modeling first oder upwind, second order upwind and third order MUSCL by using k-ε standard. The general procedure for this research is formulated in detail for allocations in the dynamic analysis of fluid computing. The results of this study suggest that MUSCL's third order modeling gives more accurate results better than other models.

The development of automotive technology is increasing rapidly along with the high level of competition among producers. According to data compiled by the Association of Indonesian Motorcycle Industry (AISI) in 2015-2016 there was an increase in the number of motorcycle sales of about 4.6% or an increase of 5.8 million units for. The high level of sales and technological developments leaving the problem for the automotive business itself. One of the problems that often happens is the slow absorption of technological progress to the hands of users. Motorcycle service workshops and bottom-line businesspeople are very vulnerable to the impact of this technology transfer process. This situation indirectly affects the sluggish economic movements among the bottom because they lack access (training and access to the latest sources of technology references). This situation should be a special concern for the top of the automotive business activists and also practitioners / academics related to the rapid development of technology produced can give impacts of rapid economic growth also for lower-level business people.The Up Grade skill program of motorcycle service involves a partner group (workshop) consisting of 6 people mechanics who are still in the beginner category. The training materials provided are tune up, conventional motorcycle overhaul (carburetor) and tune up injection motorcycle. Training is held for 2 full days (equivalent to 20 hours) with competency test process on the last day of the program. From the training activities can be seen the improvement of mechanical competence obtained from the pre-test at the beginning of the training and post test at the end of the activity.Through the program of Community Service of Regular Science and Technology is expected proposers can play its role as an academic in helping accelerate the process of technology transfer, especially for lower-level business people who do have limited access to technology. After the end of this program is expected to increase the mechanical skills as well as the increased service quality and competitiveness of partner workshops.

Tingkat keterserapan lulusan SMK di Pesisir Selatan untuk bekerja sesuai bidang keahliannya yang ada masih kurang dari 50% dari jumlah lulusan. Hal ini disebabkan oleh keterbatasan fasilitas pratikum, ilmu yang diberikan kurang up to date, serta jumlah guru produktif yang masih kurang. Pembelajaran kewirausahaan masih bersifat teoritis, belum menyentuh ide-ide kreatif siswa untuk bisa menghasilkan produk-produk yang layak jual sesuai dengan ilmu yang mereka pelajari. Pertumbuhan lapangan kerja tidak sebanding, menjadikan tingkat persaingan bekerja semakin ketat. Untuk menyiapkan lulusan yang siap kerja maka tim memberikan pelatihan keterampilan dan program pendampingan untuk meningkatkan kreatifitas dan inovasi siswa yang akan tamat dalam menghasilkan produk-produk kreatif sebagai cendaramata dan bernilai jual di objek wisata Pesisir Selatan. Metode yang digunakan selama kegiatan pelatihan berlangsung adalah ceramah, tanya jawab, demonstrasi, dan bimbingan. Program Kemitraan Masyarakat dengan tema Rancang Bangun produk Inovatif dalam Rangka Menyiapkan Lulusan SMK Yang Mandiri, telah diselenggarakan pada tanggal 02 s.d 05 Agustus 2019, menghasilkan keluaran PKM berupa 16 unit lampu hias dari pipa paralon yang dihiasi cangkang kerang, peningkatan keterampilan peserta latih, bahan ajar kewirausahaan dan publikasi di media sosial internet. Kegiatan ini menumbuhkan ide-ide kreatif peserta latih dalam menghasilkan sebuah produk yang bernilai jual dengan memanfaatkan bahan yang ada disekitarnya.

Numerous obstacles must be overcome by vocational schools, particularly in the area of developing technical and practical knowledge. The provision of skills improvement and reskilling for teachers and students, especially in the field of Electronic Fuel Injection (EFI) in gasoline-powered vehicles, is the most fundamental issue at SMKN 1 Lembah Melintang that needs special attention, particularly for Automotive Light Vehicle Engineering (TKRO). The program's goal is to increase teachers' and students' proficiency in the use of tools and procedures for regular maintenance of the EFI system in cars. With a portion of 30:70, the participants will receive both theoretical and practical training. The results of the pretest and posttest show that this program has increased the competence and expertise of teachers and students. This is proved by significant growth from the prior competency in the use of tools and circular work steps, with student gains of 24% and teacher gains of 14%.

This research aims to develop a car air conditioning (AC) simulator. The vehicle's air conditioning system is transferred to a stand panel with an electric motor drive. The selection of an electric motor simplifies operation, maintenance, and practicality because the AC system does not require much time to warm up. The rotation of the electric motor is regulated by an inverter so that the performance of the AC system matches the actual performance. The R and D approach was selected for this investigation. The technique begins with examining an existing simulator, followed by planning, creating, expert validation, and completion of the simulator. The expert validation of the material's feasibility yielded a score of 3.73 with a highly feasible category, a score of 3.45 with a viable category for media, and a score of 3.20 with a feasible category for efficacy. It has been demonstrated that, on average, there is a 36.18 percent improvement in comprehension when this technique is utilized. Tujuan penelitian ini adalah membuat simulator air conditioner (AC) mobil dengan cara memindahkan sistem AC dari mobil ke panel stand dengan penggerak motor listrik. Pemilihan motor listrik adalah untuk mempermudah pengoperasian, perawatan serta kepraktisan karena tidak butuh waktu yang lama untuk pemanasan sistem AC. Sebuah inverter digunakan sebagai pengatur putaran motor listrik, sehingga kinerja sistem AC sesuai dengan kinerja sebenarnya. Metode R and D dipilih dalam penelitian ini. Metode diawali dengan mengamati simulator yang sudah ada, merencanakan, mengembangkan, melakukan validasi simulator oleh ahli, dan finalisasi simulator. Hasil validasi ahli untuk kelayakan materi memperoleh nilai nilai 3.73 dengan kategori sangat layak, untuk media memperoleh nilai 3.45 dengan kategori layak, serta untuk keefektifan dengan nilai 3.20 dengan kategori layak.

The purpose of this study is to design a simulator for a car air conditioning system as a learning medium, so that the learning objectives can be achieved properly and in accordance with the expected competencies. This design uses an electric motor drive to drive the AC system compressor so that it is easier to operate and does not produce air pollution and is made with a design that can be moved easily by having sturdy wheels. The electric motor is also equipped with an inverter that can adjust the rotation of the motor as in the conditions of a real car engine. This research model uses Research and Development which includes the stages: problem analysis, seeking information, designing a model, validating the design, evaluating the model, testing the model, revising the model, wider testing, finalizing the design. The results obtained are the creation of an AC simulator that has been validated by experts in terms of media and material in the very feasible category, then from the user side with 25 respondents giving a value in the very feasible category for use in learning. The increase in competency occurred by 23.90% with a comparison of the pretest value with the posttest value.
