Efisiensi Termal Cross Section Double Drum Water Tube Boiler Pengaruh Rasio Udara Bahan Bakar Solar Berbasis Water Level Control (AM61-F) Pada Produksi Saturated Steam Proses Kontinyu
Get PDFA Boiler is a type of closed vessel that transfers heat energy from the combustion process to water until it becomes hot steam (steam). To produce good steam, the Boiler must be reliable in its heat transfer system, mass transfer system and hydrodynamic system. This will also have an impact on cost, thermal efficiency and the environment. In order to produce steam, good combustion and proper water level regulation are required. Combustion is an exothermic reaction that takes place very quickly, which releases energy in the form of heat and flame and is able to spread heat through a medium. In order for combustion to occur optimally, it must pay attention to the value of the Air Fuel Ratio (AFR). The regulation of the water level also affects the steam produced. This study studies the variables of air fuel ratios (Air Fuel Ratio) 16, 18, 20, 22 and 24 as well as water level levels of 20%, 30%, 40%, 50% and 60%. From this study, a flame temperature value of 685.9°C was obtained with a thermal efficiency of 69,61% Specific Fuel Consumption 0,0000339 kg/kJ which is in the 4th experiment, namely Air Fuel Ratio 22 and Water Level 50% with optimal combustion and steam production results.

A Theoretical Analysis of Consumer Behaviour for Voters in Ghana
Get PDFThis paper identifies evidence of political marketing and, more specifically, consumer-oriented political marketing to analyse the theories of consumer behaviour and identify evidence of consumer behaviour in marketing in the behaviour of Ghanaian voters. The examination used quantitative research to analyse the relationship between three elements: (1) psychology, (2) personal and (3) social to understand the theory of the relationships between campaign messages and voters’ behaviour. Data were collected through a cross-sectional survey with semi-structured questionnaires administered to 7203 randomly selected respondents from participating political parties and voters in Accra, Ghana. Data received were analysed using descriptive statistics and Structural Equation Modelling (SEM). Findings revealed a statistically significant relationship between the behaviour of voters in Ghana and the campaign messages of political parties. This paper concludes that there are opportunities for political marketing and change in voter behaviour. Still, sufficient attention should be given to the understanding of consumer behaviour theory that recognizes the behavioural dynamic of voters in the design of effective campaign messages that are responsive to voters’ needs
Studi Pengaruh Temperatur Aging terhadap Kekerasan Vickers, Ketahanan Impak, dan Korosi pada Aluminium Paduan
Get PDFAluminum is a chemical element with the symbol Al with atomic number 13. Aluminum belongs to the light types of metals. Its electrical conductivity is 60% more than that of copper, so it is also used for electrical appliances. Aluminum is a reactive metal, so it is easily oxidized with oxygen. Aluminum is lightweight, strong, rust-resistant and malleable, aluminum is also utilized in many ways, such as materials for making fuselages, used in high-voltage cables and much more. This study aims to find out how temperature aging affects vickers hardness, impact toughness and corrosion in aluminum alloys. The aluminum used is 6000 series aluminum and is cut into workpieces according to ASTM standards. The applied method is by heat treatment precipitation hardening or age hardening. From the results of microstructure photo testing, it was found that the higher the aging temperature, the more amount of precipitation is formed and the distribution of precipitation is more even. However, when the heat treatment solution is performed, the precipitation decreases because at the same time the atomic void in thermal equilibrium at high temperature remains in place or a precipitate or so-called super saturated solute solution occurs. In hardness testing, the hardness continues to increase as the aging temperature increases and the maximum hardness is found at a temperature of 200oC with an average value of 86.6 kg/mm2. Meanwhile, the impact strength decreases with the increase in aging temperature and the highest impact strength at 120o C with a value of 0.619 j/mm2. In the corrosion test, as the temperature of aging increases, the aluminum is more resistant to corrosion the maximum value is obtained at 0.00251 mill/year at a temperature of 200o C
