Abstract

Reverse Engineering (RE) is a process in manufacturing that aims to reproduce or recreate existing models, either components, sub-components, or products without using existing design documents or working drawings. Through this reverse engineering idea, the process of making the Pump Block component is started with making part and mold design, making sand casting, then finished with machining processes. The machining process that is carried out is the turning process, the milling process, and the drilling process which is assisted by using jigs and fixture to make it easier on finishing the Pump Block parts in the machining process. By using the processes, so it is produced the similar pump block that is resemble with desired original object.

Abstract

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

Abstract

Telah dilakukan rancangbangun dan penyuluhan penggunaan instalasi peralatan hidroponik untuk Madrasah Tsanawiyah Negeri 7 (MTsN 7) Kota Padang dalam kegiatan tim Pengabdian Kepada Masyarakat Politeknik Negeri Padang. Tujuan dari kegiatan ini adalah dalam rangka Tridharma perguruan tinggi, dan untuk menciptakan lingkungan yang asri di sekolah tersebut. Untuk mempertahankan keasriannya, maka tim pengabdian PNP bersedia menyumbangkan instalasi hidroponik, agar MTsN mempunyai green house untuk membudidayakan tanaman hias, tanaman obat-obatan, dan sayuran. Kegiatan ini dilakukan mulai dari rancangbangun, setting peralatan, dan penyuluhan cara menggunakannya. Hasil dari kegiatan ini menunjukan antusias yang besar dari sivitas akademika MTsN 7 untuk menciptakan lingkungan yang sehat dan asri. Sehingga Adiwiyata Nasional yang sudah diperoleh dapat dipertahankan.
