The community service team from the Padang State Polytechnic majoring in Mechanical Engineering has implemented a community service program which is participated by members of the affluent farmer group, namely the local community, which is located in Batu Gadang, Kec. Lubuk Kilangan which owns agricultural land. This community service provides rice mower machine assistance to affluent farmer groups. Community service is expected to be able to help all members of a prosperous farmer group, who previously needed a lot of manpower for post-harvest, now no longer need a lot of agricultural labor and also with this community service assistance, prosperous farmer groups can save time and costs for post-harvest. The high hopes of the community service team for affluent farmer groups are to be able to make the most of this machine and support the success of affluent farmer groups to increase rice production and overcome the need for extravagant labor at post-harvest time. And it is highly hoped that the prosperous farmer groups will be able to use this rice mower machine, and can assemble agricultural tools with a modification of the carrying type lawn mower to be used as a rice cutting machine.

Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine's blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator. Wind electric systems are one of the most cost-effective home-based renewable energy systems with zero emissions and pollution. Many factors that influence the performance of wind turbines such as wind speed, blade shape, and number of blades. In Generator, Coil number of turn (N) also influence performance of wind turbine. Manufacture of wind turbine prototype as a learning medium to facilitate students in understanding the concept of wind electric system. Results of the test prototype wind turbine if the wind speed the greater the resulting voltage will be higher, the Coil number of turn (N) also affects the voltage generated.

Kanagarian Salo Kec. Baso Kab. Agam memiliki beberapa peternakan puyuh yang dikelola secara mandiri. Berdasarkan survey yang dilakukan pada awal 2020 di peternakan puyuh kanagarian Salo, pakan puyuh diaduk secara manual menggunakan skop sehingga hasil adukan tidak merata ditiap bagian. Pengolahan pakan yang baik sangat berpengaruh pada produksi telur puyuh. Pakan yang baik memiliki komposisi pengadukan yang merata di setiap bagian ransum, sehingga puyuh mendapat gizi sesuai kebutuhannya. Berdasarkan permasalahan tersebut sangat perlu dibuatkan mesinpengaduk pakan unggas. Tujuan pengabdian masyarakat ini adalah menyediakan mesin pengaduk pakan ternak puyuh kapasitas 400 kg untuk peternak di Kanagarian Salo. Diharapkan proses pengadukan pakan menjadi lebih efektif dan efisien. Metoda yang digunakan untuk menyelesaikan permasalahan mitra adalah adalah rancang bangun alat pengaduk pakan yang aplikatif berdasarkan kebutuhan mitra dan sosialisasi cara pemakaian mesin pengaduk. Hasil kegiatan pengabdian ini adalah tersedianya mesin pengaduk pakan puyuh kapasitas 400 kg untuk peternakan puyuh di kanagarian salo dan pemahaman peternak dalam pengoperasian mesin. Kata kunci : pakan unggas, pakan puyuh, mesin pengaduk, tingkat campuranhomogen ABSTRACT Kanagarian Salo Kec. Baso Kab. Agam has several independently managed quail farms. Based on a survey conducted in early 2020 quail farm in Kanagarian Salo, the quail feed ingredient was stirred manually using a shovel that produce Non-homogeneous mix. Good feed processing is very influential on the production of quail eggs. A good feed has an even mixing composition in every part of the ration, so that the quail gets the nutrition their needs. Based on these problems, a poultry feed mixer machine is needed. The method used to solve the problems is the design of an poultry feed mixer machine based on the needs of partners and socialization of how to use the mixer machine. The result of this activity is the availability of a poultry feed mixer machine with 400 kg capacity for quail farms in Kanagarian Salo and the understanding of farmers in operating the machine. Keywords: poultry feed, quail feed, mixing machine, degree of mixing, homogen

Mesin Frais termasuk mesin perkakas yang mampu melakukan banyak variasi bentuk pekerjaan dibandingkan dengan mesin perkakas lainnya. Di bengkel Politeknik Negeri Padang mesin tersebut digunakan untuk keperluan praktek mahasiswa dan untuk proses produk sudah berumur 30 tahun. Benda kerja dari hasil praktek milling mahasiswa kualitasnya kurang baik yaitu adanya penyimpangan dari karakteristik geometri (ukuran, bentuk dan kehalusan). Keakuratan kinerja mesin perkakas sangat penting dalam proses manufaktur sehingga dapat menghasilkan produk yang berkualitas tinggi. Tujuan dilakukan pengujian ini adalah untuk mengetahui besarnya penyimpangan geometrik yang terjadi pada keadaan statik pada mesin perkakas Frais Type Schaublin 13. Penyimpangan ketelitian geometrik suatu mesin dapat diketahui melalui pengujian yang mengacu pada standar yang baku. Pengujian dilakukan dengan membandingkan nilai penyimpangan hasil pengujian yang telah diambil dengan nilai penyimpangan izin menurut standar ISO 1710. Penyimpangan terjadi pada pengukuran kelurusan dan pengukuran kesejajaran. Pada pengukuran kelurusan diperoleh rata-rata penyimpangan ketelitian geometris adalah 0,0267 dan 0,0228 sedangkan penyimpangan maksimum yang diizinkan adalah 0,02 dengan jarak 300 mm. Sedangkan pengukuran kesejajaran didapatkan rata-rata penyimpangan ketelitian geometris mesin adalah 0,0741 dan 0,0783 dan penyimpangan maksimum yang diizinkan adalah 0,025 dengan jarak 300 mm. Pengukuran kesejajaran ketelitian geometris mesin melebihi batas penyimpangan maksimum yang diizinkan. Berdasarkan hasil pengukuran kelurusan dan kesejajaran didapatkan penyimpangan yang melebihi batas yang diizinkan pada mesin yang digunakan. Mesin tersebut seharusnya tidak dipakai untuk pekerjaan-pekerjaan yang memiliki kepresisian yang tinggi, dan sebaiknya diganti dengan mesin yang baru.

Design and manufacture of coffee pulper machines have been carried out with the aim of completing the needs of the coffee farmer groups when harvesting in the Kayu Aro area, Kerinci. The steps in designing and manufacturing a coffee pulper begins with a literature study, design and calculation, the process of making the tool and ends with testing the tool. Engineering drawing design is done by modeling in SolidWorks software. Coffee peeler machine with a capacity of 4 kg/min, with a machine size of 730 mm x 320 mm x 1040 mm, using an electric motor 1 HP 1420 rpm, with a frame using an elbow profile 40 mm x 40 mm x 3 mm. The transmission system uses an electric motor with an initial rotation of 1420 rpm to 364.6 rpm. In the 2 pulley component D = 74.6 mm and 290.5 mm, V-belt type B No.52, 1 solid shaft D = 25 mm. Initial test results using 2–5 kg of wet coffee beans take 30.07–77.20 seconds, and the skin has separated from the beans cleanly. These results show that the engine capacity is 235.62 kg/h, so that the desired target is met with relatively low operating costs. The existence of this tool will be able to help the process of separating the skin and coffee beans, so that the quality of coffee production will increase. Keywords: coffee, coffee machine, design and construction, farmer groups

Circular cylinder has a strong adverse pressure gradient. When a fluid flows around the circular cylinder, it will produce aerodynamics force. One of them is the drag force which strong enough. Hence, control of flow need to reduce the drag force with placed a disturbance body on the upstream side. The purpose of this study is to compare and complement the experimental research of drag reduction that has been done before. The aerodynamics characteristics of the disturbance body and cylinder are modelled in two dimensions Unsteady-RANS by using fluent with turbulent flow. It is found that the mean drag and the lift fluctuation of the cylinder can be reduced by the upstream disturbance body with the s/D = 0.107 (here s and D are side length of the disturbance body and the diameter of cylinder, respectively). The position of the disturbance body is varied at (α) 20º, 30º, 40º, 50º and 60º with a gap distance (δ = 0.4mm). Reynolds number based on cylinder diameter ReD = 3.48x104. Fluid interaction between circular cylinder with two disturbance body can increase boundary layer transition from laminer to turbulent to produce small drag. It is found that the characteristics of the flow significantly depend on the position of disturbance body. The optimum condition for the drag force reduction is at the angle α = 30º about 53 %.
