Abstract

Seiring dengan perkembangan peradaban manusia, tingkat kebutuhan energi juga semakin meningkat dan mengakibatkan menipisnya bahan bakar fosil sebagai sumber energi utama. Oleh karena itu diperlukan energi alternative yang terbarukan. Sungai Batang Kularian Kinali Pasaman Barat mempunyai potensi daya yang dapat dimanfaatkan sebagai sumber energy yang terbarukan. Pembangkit listrik tenaga mikro hidro (PLTMH) merupakan salah satu bentuk energi alternatif yang mengolah energi potensial air berubah menjadi energi listrik yang berguna untuk kebutuhan hidup masyarakat. Perencanaan PLTMH dimulai dari survey lokasi perencanaan di Sungai Kularian Kinali Pasaman Barat. Survey dilakukan untuk mendapatkan data perancangan berupa head dan debit air. Data tersebut dapat digunakan untuk menentukan besarnya potensi energi pada lokasi perencanaan PLMTH. Pada perencanaan PLTMH di Sungai Kularian Kinali Pasaman Barat diperoleh data debit air seluruhnya 0,4 m3 /s dan potensi energi listrik sebesar 25 kW. Perencanaan pipa penstock menggunakan pipa berdiameter 500 mm.

Abstract

Solar thermal energy is one of the potential energy to be explored and developed further as a source of backup energy. To be able to directly utilize solar thermal energy to heat water can be used in a device that can collectsolar energy to the Earth's surface and convert it back into useful heat energy. This device is called the solarcollector. Solar collectors can be defined as a heat transfer system that generates thermal energy by harnessingthe Sun's radiation as the main source of energy. After testing by varying the flow capacity of 3 litters /minute upto 10 liters/minute, then in the temperature of the fluid can come out (Tout) is the highest of 61,9 C, which ispresent on the stream discharge 7,5 litters/minute. And the highest efficiency in the discharge flow of 5 litters/minute is equal to 86,54%. The results of this test indicate the efficiency of the collector surya.

Abstract

Heat Exchanger is a device that is used to transfer heat from one medium to another. At Environment ITP there are many kinds of dryers, but they are still depend on the intensity of sunlight. The Heat exchanger is an alternative to the drying process in rainy season. Base on the direction of fluid flow, heat exchanger is includes a heat exchanger types of cross flow. Then the air entering the dryer chamber does not mix with the smoke produced by burning sawdust on the furnace fuel. Air enters through the input with the of a blower and continue towards the composition of the pipe as a heat transfer, hot air continues to flow towards the output. In this tool comes two heat transfer process of heat transfer is natural convection and forced convection heat transfer. To determine the effectiveness of this tool, is influenced by several variables such as : speed, burnbing time, the mass of sawdust, pipe surface temperature, the temperature of the cold air and out, the temperature of hot air inside and outside.

Abstract

Rooftop solar copra dryer tool is an instrument used for drying copra with capacity ± 40 kg, for one drying. The purpose of this research is to see how to efficiency drying in a series connectivity on copra process of drying. Using the dryer solar can exsiccate drain agricultural products. Where the work plase, sunlight absorbed or strored through solar collectors, heat will come from the collector come into a system of air flow to the piping system and forward to the drying. Design tool dryer aims to exsiccate copra of the water is decreased from 52.68 % until 5-6 %. Medium dryer is the heat produced by the capture of the sun and distributed for ciblyin to the drying chamber they would be used for drying copra. After doing research with the experimental method to directly observe and measure the way things are done in the dryer and then do the processing and evaluation of test data. From the results of tests and calculations, drying wits series to get a final moisture content of the materiall is achieved after 25 hours of drying by using a tool maker Rooftop wits 5.97 %. Final moisture content of the materiall is achieved after 25 hours of drying with direct drying wits 24%. Rooftop solar copra dryer appliance is more Effective and Efficient. Un contaminated by air environment (dust, sand, vermin and its other)

Abstract

One of the most important power plant system is the diesel engine, where are the diesel engine include a conversion of energy that can be converted into the energy to change into the thermal that canbe burn in the combution chamber that will be mechanical energy. In this case, it has maximal power 1000 kW it will be able 500 until 600 kW. To evaluation that problem can use the maintenance at PLTD Koto Lolo PT PLN (Persero) Ranting Sungai Penuh will do the result of maintenance to do best.

Abstract

Energy use is a major problem in the vapor compression air cooling system, especially in areas with very hot weather conditions. In hot weather conditions, the performance of the system has decreased dramatically and electricity consumption has increased significantly. Combined Condensor with evaporative cooling will increase the heat removal process by using an evaporative cooling effect that will increase the efficiency of energy use. This paper presents the study of the use of evaporative cooling and condenser. This paper mainly calculated energy consumption in steam compression cooling systems and related problems. From the results of this study, the use of condensers with evaporative cooling, power consumption can be reduced to 46% and performance coefficient (COP) can be increased by about 12%, with 1,2 kW cooling capacity.
