Abstract

Peatlands play an important role in climate change and biodiversity which is currently increasingly threatened. Peat land in Indonesia is quite extensive, which is around 20.6 million ha or 10.8% of Indonesia's land area. In Sumatra, fires in wetlands / peat are a major problem that continues. At the same time, fire is used as a tool in the use of peat land, there is high population pressure and development on the land. It is necessary to identify, study and solve fire problems based on sustainable development and conservation of peatlands. This research method is to analyze the combustion triggering caused by cigarette butts and the rate of combustion that is affected by air flow. Peat testing is carried out on peat that has been dried in the oven for 8 hours. The sample treatment by giving cigarette butts as a trigger and giving air flow with the average speed of Riau province. The maximum temperature of peat combustion is 892 ° C and the average creepage velocity is 68.37 mm/hour. Burning cannot be triggered if the peat is wet.Keywords: peat fires, fire phenomena, influence of air flow

Abstract

The limited fossil energy resources and high levels of air pollution led to increased exploration of new and renewable energy sources. Hydrogen has the potential to replace fossil fuels because there is abundant in natural and pollution-free air. The greatest problem in hydrogen is storage methods. Hydrogen storage by adsorption on activated carbon is the best method. Adsorption isotherms of hydrogen on granular activated carbon made from coal with a surface area of 885 m2/g has been implemented by using a volumetric method. Adsorption experiment has been tested at temperature of 45oC and the pressure up to 30 bar. Experiment data in the form of isotherms temperature and variations pressure were calculated to determine the adsorption capacity. Adsorption capacity data were correlated using adsorption isotherms equation of Langmuir and Toth. Adsorption isotherms equation that have result the smallest deviation is the best equation. From the experiment results, the maximum adsorption capacity is 100,91×10-5 kg/kg at isotherm temperature of 45,4°C and a pressure is 29,99 bar. The maximum adsorption capacity occurs at the maximum pressure. Correlation data of adsorption isotherms using the Toth equation has the smallest deviation of 11,73%.Keywords : Adsorption isotherms, volumetric method, adsorption capacity, adsorption isotherms equation.

Abstract

The issue of global warming and the amount of energy consumption is one of the biggest problems of the air conditioning system and refrigeration used today, so technology that isenvironmentally friendly and also energy efficient is needed. The adsorption cooling system is one ofthe technologies for air conditioning and refrigeration systems that are energy efficient and environmentally friendly because the refrigerants used do not contain haolocarbon and not usingcompressors in the system so that it saves energy. In this study a double bed adsorber adsorption system with silica gel-water is designed as an adsorbent-adsorbate. as an adsorbent-adsorbate. The adsorption cooling system contains 2 adsorber and finned and tube pieces as heat exchangers.

Abstract

Combustion chamber is one of the main components in the Combined Cycle Power plant (CCPP) that serves as a supplier of heat energy. Then by the system, the thermal energy will be converted into other forms. Combustion chamber is a major cause of irreversibility in the system. Usually, the performance of a component is evaluated by using the first law of thermodynamics (conservation of energy). However, the first law of thermodynamics only assess the quantity of energy consumption. Therefore, exergy analysis is used (based on the second law of thermodynamics is about the entropy changes) which can be studied more deeply about the quality of an energy (energy available; exergy). The aim of this study is to analysze exergy destruction of combustion chamber on Combined Cycle Power Plant (CCPP) 30 MW Teluk Lembu. Exergy analysis on combustion chamber resulting the exergy destruction is 36.46 MW and exergy efficiency is 63.29%.Keywords: combustion chamber, analysis of exergy, exergy destruction, efficiency exergetic

Abstract

The process of blood distribution before transfusion requires a cooling unit that is able to maintain the temperature, so that blood can be maintained and not damaged before transfusion. Peltier elements are chosen to be used as coolants in the blood cool box because they are small so they can be operated in a limited space and operate at 12 volt. The design carried out in this case is the manufacture of blood cool boxes for the distribution of blood over long distances. The peltier element is used type of TEC1 12706. The ability of the cold side of the peltier element based on the calculation results of 18.65 Watt which is used for cooling the box. The lowest blood cool box temperature is obtained from no load testing of 14.23 ° C and the maximum load of 23.22 ° C. And the lower the temperature difference between the hot side and the cold side, the higher the amount of heat absorbed, and will affect the value of the Coefficient of Performance, which will be greater if the absorbed calorific value is greater.Keywords: Peltier Element, Blood Cool Box, Coefficient of Performance.

Abstract

Global warming and high electrical energy consumption issues have been attention all human in the world. Among various technologies especially refrigeration that being developed to prevent those problem. The refrigeration vapor compression cycle, which impaction on the ozone layer and potential damage of global warming because contains HCFC and CFC and Beside that, the highly electrical energy consumption might be happen. In this research proposed a designing and manufacturing of adsorption cooling system with a double bed adsorbed with capacity 5000 Btu/h. The methanol was used as adsorption and activated carbon as adsorbent, which have characteristic zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP) that was expected to be able to decrease damage to the ozone layer and minimize the electrical energy consumption. The method used in this research was the design.

Abstract

Based on WHO Standards, Indonesia has not fulfilled the minimum blood supply for its 258 million populations. So, when needing certain types of blood that are available outside an area must go through the process of blood distribution. During this time, the distribution only uses ice packs in maintaining blood temperature. The use of ice packs in the distribution process is very risky because ice packs quickly adjust to the ambient temperature. Then, the temperature in the blood is feared more than the rule. Therefore, the design of blood carrier box with cooling components from the peltier element are intended to overcome the problem of blood distribution by being able to maintain blood in the temperature range of 2-10oC. The electrical power maximum of cooler design for 7x350 ml blood bags was obtained at 283.2 Watt. Keywords : Peltier Element, Blood Carrier Box

Abstract

Due to the very rapid population growth, the need for clean water will continue to increase year by year. This makesthe availability of clean water a major issue today, especially for coastal people. Coastal residents have to buy cleanwater in their daily lives, and coastal residents also use rainwater. However, the availability of clean water still existsin nature. In the dry season, it is very difficult to get clean water. One solution to this lack of clean water is to obtainclean water by desalination. Desalination of seawater is the process of maintaining clean water by removing excesssalt from the water and using sunlight to create freshwater. This study describes an experimental study of theefficiency of solar desalination plants using solar energy. The experiments was performed with a sponge pore size of0.2 mm and an initial volume of 8 liters. With an average solar radiation of 719.9 W/m2, the desalinated air producedis 2.944 kg and the efficiency is 25.15%.Keywords : Solar Desalination, Porosity, Sponge
