Abstract

The availability of solar energy has great potential for application in the agricultural sector. Electrical power from photovoltaic cells or solar panels mainly depends on sunlight at certain times. The use of this technology can be applied to pump drives in agricultural irrigation systems. In this research, we try to measure a certain time with the efficiency of components from using solar photovoltaic (SPV) with the water discharge produced by the pump on these components. From the experimental results, it was found that the best efficiency was at 14.00 WITA with an efficiency of 57% with the panel facing directly to the sun. From pump testing, it was found that the average water flow was 20.95 liters/minute. From these performance tests, Indonesia itself has sufficient levels of solar radiation to use solar panels as an alternative to sustainable resource.

Abstract

Pelton turbine is an energy conversion medium that utilizes flow performance as a driver and produces electrical energy due to the conversion of turbine rotation. The turbine works when the turbine nozzle injects flow towards the tip of the nozzle which leads directly to the inlet surface of the turbine blade. In this research, we know the effect of nozzle diameter on the performance of turbines that produce different electrical power from various parameters, namely: nozzle diameter used; 1", ¾", 1 ½", and ½" with various nozzle opening variations of 20%, 50%, and 100%. The results obtained with a nozzle diameter of ¾" obtained maximum results with a rotation of 177 (rpm), with a power of 5,168 watts and efficiency increased to 5% at each nozzle valve opening. From these results it can be said that the magnitude or size of the nozzle influences the performance of the turbine where the efficiency of the performance is directly proportional to the rotation and power produced.

Abstract

Efisiensi sistem refrigeran dengan fungsi sebagai fluida yang menyerap panas dalam sistem sehingga terjadi penurunan suhu  melalui mekanisme evaporasi dan kondensasi. Percobaan ini dilakukan untuk mengetahui refrigeran yang mempunyai dampak laju pendinginan terbaik dengan tingkat temperatur yang berbeda sehingga dapat diamati laju pendinginan dari refrigeran R-134a, R-32, R-410a, dan LPG. Dalam prakteknya menggunakan simulator pendingin sebagai media pembelajaran dalam menerapkan prinsip kerja mesin refrigerasi. Metode penelitian yang dilakukan adalah dengan mengukur temperatur pada waktu 30 detik untuk pengambilan 1 data dan pengambilan data dilakukan selama 300 detik untuk menghasilkan 10 data pada tiap jenis refrigerant pada tekanan 10 Psi. Hasil penelitian menunjukkan refrigerant jenis LPG memiliki tingkat penurunan temperatur paling rendah diantara jenis refrigerant yang lain. Hal ini dikarenakan kinerja LPG dengan ODP sama dengan nol dan nilai GWP rendah. Kesimpulannya sistem pendingin domestik dapat menggunakan refrigeran jenis LPG di untuk penurunan temperatur yang lebih rendah. Refrigerant system efficiency by functioning as a fluid that absorbs heat in the system resulting in a decrease in temperature through evaporation and condensation mechanisms. This experiment was conducted to find out which refrigerant has the best cooling rate effect at different temperature levels so that the cooling rates of R-134a, R-32, R-410a, and LPG refrigerants can be observed. In practice using a cooling simulator as a learning medium in applying the working principles of refrigeration machines. The research method used is to measure the temperature for 30 seconds for 1 data collection and 300 seconds for data collection to produce 10 data for each type of refrigerant at a pressure of 10 Psi. LPG type refrigerant has the lowest temperature drop among other refrigerant types. This is because the performance of LPG with ODP is equal to zero and GWP is low. In conclusion, domestic refrigeration systems can use LPG type refrigerants for lower temperature drops.
