Hydram pump is a solution to overcome the problem of water demand, especially for highland areas. Hydram pumps can be used for rice field areas because they do not require an electric energy source. Operating parameters at the hydram pump greatly affect the efficiency of the hydram pump. In practice in the field, altitude is not difficult to obtain, especially for mountainous areas. However, for some highland areas, often to get a certain height must be with a large elevation distance hydram pump to water sources. In this research, a change in the angle of inlet variation will be conducted on the efficiency that occurs. So that with this research, it can be a benchmark for determining the distance of a hydram pump to a water source. The highest water discharge that can be generated from a 1 in size PVC hydram pump, 2.75 m inlet height, 5 m outlet height is 1.5 x 10-5 m3/s. while the lowest water discharge in the test carried out is 0 m3/s at the number of pendants 1 and the pump inlet angle is 45°. The inlet angle greatly affects the resulting flow rate. The inlet angle of 30° results in a higher water flow rate of 1.44x10-5 m3/s at the number of pendulum 2 compared to the 45° inlet angle which only gets 9.44x10-6 m3/s even up to 0 m3/s at the number of pendulum 1.

Heubeulisuk Village is a village located in Argapuran District, Majalengka Regency. Similar to other villages, this village has a Village Owned Enterprise (BUMDes). One of the activities of the BUMDes is the production of wooden wall clocks and several other crafts made of acrylic material. Wood Size craftsmen until now only use a simple cutting saw to make the craft and acrylic using a hand drill. The chainsaws facilitated by the local village government are not as sophisticated as imagined. With the BUMDes CNC Router machine, it is able to increase the amount of production and minimize the production time required. In this service program scheme, training on the use of CNC Routers for BUMDes Heubeulisuk will be carried out starting assembling, preparing cutting/chiseling tools, making CAD models, CNC controllers to execution/feeding of workpieces.

Sprocket merupakan roda bergigi yang berpasangan dengan rantai, yang digunakan pada conveyors dimana proses pembuatannya diproduksi melalui proses pengecoran. Dalam proses produksi pengecoran sprocket ini melalui beberapa tahapan, diantaranya pembuatan pola sebagai media awal dalam cetakan pasir yang menyerupai tiruan dari benda yang hendak dibuat dengan pengecoran, pola mempunyai ukuran sedikit lebih besar dari ukuran benda yang akan dibuat dengan maksud untuk mengantisipasi penyusutan selama pendinginan dan pengerjaan finishing setelah pengecoran. Pembuatan cetakan pasir sebagai tempat logam cair terdiri dari beberapa bagian yaitu inti atau pola, saluran turun dan masuk logam cair. Peleburan material merupakan hal penting yang dilakukan dan diperhatikan dalam pengecoran logam dengan tungku induksi (Induction Furnace) kapasitas 200 kg. Material yang digunakan dalam pembuatan sprocket adalah logam FCD 450 (Ferro Casting Ductile) memvariasikan kadar karbon dan silikon. FCD 450 atau besi cor nodular yang memiliki sifat mekanik lebih baik dari besi cor yang lain.

The sand sieving machine, shaker screen, crankshaft rotational motion system, is a machine that facilitates building work in separating the mixture of sand and gravel. In the design and analysis related to the selection of the frame model in order to determine the strength of the material in holding each component of the sand sieving machine, this research uses solidwork software, based on the results of the solidwork software simulation, the stress value in the sieving tank is 3,303 N/mm2, the displacement value is 2,325 mm, the safety factor by means of a simulation of 4,059. The capacity of the shaker screen sand sieving machine has a volume of 0.824 with a length of 160 cm, a width of 70 cm and a capacity of accommodate wet and dry sand media weighing 30 kg.

Pelatihan Software Vectric Aspire untuk BUMDes Desa Heubeulisuk Engkos Koswara; Nasim; Whydiantoro; Budiman; Intan Kusumadewi

Salah satu kegiatan BUMDes Desa Heubeulisuk adalah kerajinan kayu berupa jam dinding dan semacamnya. Pembuatan kerajinan kayu ini masih dibuat dengan cara konvensional dengan bantuan gergaji ukir dan bor berukuran kecil. Akan tetapi, dengan peralatan yang sederhana BUMDes tersebut menerima banyak pesanan dari berbagai instansi hingga kalangan masyarakat. BUMDes Desa Heubeulisuk telah mengenal CNC router dengan program yang digunakan GCam Software dan kontroler menggunakan GRBL. Dengan software tersebut CNC router telah dapat digunakan dengan baik, akan tetapi karena softwarenya lebih sederhana maka produk yang dibuat terbatas. Untuk selanjutnya, pengenalan Software Vectric Aspire akan diberikan kepada BUMDes Desa Heubeulisuk. Dengan software Vectric Aspire, produk yang dihasilkan dapat lebih beragam hingga bentuk ukiran sketsa. Harapan dengan dikenalkannya software tersebut, pekerjaan BUMDes untuk pembuatan jam dinding kayu hingga ukiran sketsa dapat lebih terbantu. Tujuan dari penelitian ini adalah membantu proses pembuatan kerajinan kayu berupa jam dinding dan lain sebagainya hingga ukiran dalam material akrilik. Dengan software Vectric Aspire, produk gambar lebih komplek akan tetapi proses pembuatan model cukup mudah dilakukan
