Abstract

Archimedes Screw turbine is a type of turbine that can operate at low heads. One of the parameters that influences turbine performance is the tilt angle of the turbine shaft. This research aims to determine the effect of the turbine shaft tilt angle on the performance of the Archimedes screw turbine using experimental methods. The experiment was carried out in the river of Pematang Gajah Village, Jambi Province, by varying the tilt angle of the turbine shaft, namely 10°, 20°, 30°, 40°, and 50°. The test results showed that the highest turbine efficiency occurred at a turbine tilt angle of 30° with an average efficiency value reaching 78%. This condition occurs because the flow through the turbine blade is less compared to other turbine shaft tilt conditions so that the fluid force is completely converted into energy. The electrical energy produced by turbine generators can reduce dependence on electricity supplies from the central grid and become more energy-independent. In addition, stable and affordable energy sources can improve the quality of life and support the social and economic development of society.

Abstract

Usaha kripik tempe di Kelurahan Payo lebar Kota Jambi belum berkembang dengan baik, aspek aspek yang mempengaruhi perkembangan usaha tersebut adalah : aspek produksi/pengolahan, manajemen usaha serta distribusi pemasaran. Permasalahan aspek produksi berkaitan dengan lama waktu pengirisan tempe, pengirisan tempe masih menggunakan pisau secara manual, sedangkan aspek manajemen Usaha berkaitan dengan pengolahan usaha belum adanya pembagian tugas, selanjutnya permasalah distribusi adalah keripik tempe yang sudah ditrisbusikan ke penjual tidak diketahui jumlah ini akan mempengaruhi dalam produksi selanjutnya. Solusi yang ditawarkan dalam kegiatan ini berupa bantuan alat dan pelatihan usaha pemasaran untuk mengembangkan usaha keripik tempe yang telah dimiliki oleh kelompok UMKM tersebut. Kegiatan yang telah dilakukan berupa: pembuatan mesin pengiris tempe, pembuatan sistem informasi distribusi keripik tempe serta pelatihan pemasaran menggunakan pemasaran dalam jaringan (daring). Dalam hal ini akan dilatih penjualan menggunakan program aplikasi beserta pemdampingan. Sehingga mitra dapat melaksanakan penjulan produk keripik tempe dengan lebih luas daerah pemasarannya, pelatihan manajemen keuangan dan strategi usaha.

Abstract

The performance of a centrifugal pump is influenced by the design of the impeller, one of which is the number of impeller blades. The objective of this study is to determine the optimal impeller blade number geometry for a centrifugal pump. The type of impeller used is a backward-curved radial impeller with variations in the number of blades: 5, 6, 7, and 8. The impeller and pump casing were fabricated using a 3D printing machine with PLA filament material. The results of the study show that the highest pump discharge occurred with 8 blades, reaching a flow rate of 41.34 liters per minute at a speed of 2541 rpm, with a pump efficiency of 33.69%. The greater the number of blades, the higher the efficiency and capacity of the pump. However, this condition needs to be further reviewed for additional blade numbers to determine the optimal impeller geometry for centrifugal pump design.
