Abstract

Abstract: Comparison between solar energy and halogen lights on efficiency of photovoltaic multicrystalline module. From various studies previously showed that the difference in the efficiency of the solar cells to the effects of the intensity and temperature of the surface of solar panels on the various types of solar cells. This study discusses the effect of temperature on the type Multicrystalline solar panel efficiency by using a simulation of light as a substitute source of the sun. The test is performed measurements of the parameters used to analyze the effect of light on the efficiency of solar panels. The results were obtained value of the highest efficiency at light power of 300 watts at 2.19% at the panel surface temperature of 31,3 0C, then 500 Watt lamp at a temperature of 2.13% and the latter 33,6 0C 1000 Watt lamp with efficiency values of 2.06% on the panel surface temperature of 34,5 0C.

Abstract

Fuel Oil Heater in Steam Power Plant (PLTU) at Tello Makassar, a heat exchanger type of heater that serves to heat the oil residue by using steam heat generated in the boiler. This study aimed to determine the effectiveness of water vapor to reduce the viscosity of oil residue that can be used as fuel by using fuel oil heater. Measurements were performed immediately when the temperature and pressure of water vapor and residual oil at the input and output unchanged (constant) for 1 hour. The results showed that the effectiveness is influenced by the amount of heat absorbed by the residual oil by 1726.083 W and the amount of heat released by the steam that is 1764.988 W with a value of 68.7% effectiveness.

Abstract: Configuration of Serpentine-Parallel and Parallel-Serpentine in Solar Hot Water Tube Thermosiphon System. The aim of this research is to compare the performance of two differences tube configuration in solar hot water collector thermosiphon system. Not only the tubes configuration are not the same, but also the collector materials, such as hot water reservoir and heat absorber are differences. For example, fiberglass and stainless steel reservoirs are compared in terms of long-lasting heat isolation. Likewise, copper tubes configuration between serpentine-parallel and parallel-serpentine are shown in association with mass flow rates and times consume to heat the water within the tubes. The test results show that parallel-serpentine configuration has higher performance (around 50%) than that of serpentine-parallel (approximately 35%). It is possibly because of fluid velocity within the tube configuration.   Keywords: serpentine-parallel, parallel-serpentine, solar hot water, thermosiphon

Abstrak: Komparasi energy surya dan lampu halogen terhadap efisiensi modul phototovoltaic multicrystalline. Dari berbagai penelitian sebelumnya menunjukkan bahwa adanya perbedaan efisiensi sel surya terhadap pengaruh intensitas dan temperatur permukaan panel surya pada berbagai jenis sel surya. Penelitian ini membahas mengenai pengaruh temperatur terhadap  efisiensi panel surya tipe Multicrystalline dengan menggunakan simulasi cahaya lampu sebagai sumber pengganti matahari. Pengujian ini dilakukan pengukuran terhadap parameter yang digunakan untuk menganalisa pengaruh cahaya lampu  terhadap efisiensi panel surya.  Dari hasil penelitian diperoleh nilai efisiensi tertinggi pada daya lampu 300 Watt sebesar 2,19% pada suhu permukaan panel sebesar 31,3 0C, kemudian lampu 500 Watt sebesar 2,13% pada suhu 33,6 0C dan yang terakhir lampu yang 1000 Watt dengan nilai efisiensi sebesar 2,06% pada suhu permukaan panel sebesar 34,5 0C.

Abstract

Cross water turbine is a water turbine radial flow where the flow of water in and out of the rotor through the rotor peripheral circle of the same. These turbines are often used for Power Plant Mikrohodro. For the characteristics of this turbine is strongly influenced by the opening of the blade, as well as the load on the turbine wheel each valve opening. Thus it is necessary to do research on the relationship between the load and adjust the opening round as well as the opening of the blade on each valve 500, 700 and 900. In this study, the load varied from 0.5 to 5 kg at the opening of the valves 500, 900 700dan. The research method used is a real experimental method. From this study it was found that the change in the valve opening is different loads affect the performance of cross-flow water turbines. Nt 224.6 kW biggest, biggest Nh 231.9 kW and the greatest efficiency is 96.85% obtained at the opening of the valve 900, a load of 5 kg with a rotation of 250 rpm.
