Abstract

ABSTRAKThe use of fossil energy for conventional power plants in the long time will run out of oil, gas and coal reservoir. Therefore the renewable energy utilization that more environmentally friendly and renewable concepts such as wind and solar heat should be optimized. Two kind of potential renewable energy resources in Indonesia that should be optimized are wind power and solar energies. They will be complement each other, in the dry season the sun will be role while in the rainy season wind power will be more dominant.This hybrid concept combining solar cell panels and Savonius turbine to gain a greater electrical output than the solar cell panels and Savonius wind turbine that operate in their owntask. A Single stage Savonius wind turbines are made three design types to find the best design that can convert more energy from any wind direction. A solar cell panel is placed under the sun to produce current and voltage from sun light. The energy summation data will be recorded by Data Aquisition System.From The measurement and data analysis results, the electrical power generated by prototype of  hybrid system is  7,5 watt. This value is greater if compare to the power generated by solar panels and wind turbines separatelly. Keywords : Hybrid System, Savonius VAWT, Solar Cell, Electric Power Generation

Abstract

Use LHE (Energy Saving Lamp)  that  use electronic  ballasts  will  cause harmonics, both  current  and voltage harmonics and the harmonics will result in a poor  electric  power quality.  On the other hand LHE that uses electronic ballasts have good properties in converting electrical energy into light, because it has an efficiency of above 80%. This research aims to analyze the activity electric power quality in the distribution network due to load LHE with electronic ballast. We then measured  with  a  laboratory  scale and continued analysis using  the program, for the  issues  analyzed  include: the  use  of electronic  ballasts will  cause  harmonic currents and voltage, harmonics and odd harmonics influential 3rd harmonic dominant, harmonics will affect the quality of electric power . thus will follow up effort to minimize the presence of harmonics in particular harmonic currents and harmonic influence further analyzed for capacity LHE group with large-capacity load on the distribution network.  In order to save electrical energy, mainly for lighting, energy-saving lamps can be used. Those lamps, which use electronic ballast and added by hybrid filter, can reduce negative effect due to harmonic, so that efficient condition in load and optimal condition in distribution network can be obtained. This study was carried out by a simulation with PSIM program version 9.0 and a reference to minimize current harmonics in such energy-saving lamps using electronic ballast to increase the quality of electrical power.Results of the study show that reduction in large current harmonics of 10% due to AC-DC rectification was because of electronic ballast use. Moreover, some efforts were found reducing the harmonic effect by using hybrid filter to meet the standards of IEC 61000-3-2 in Class C.Key Words : Harmonics, hybrid filter, electronic ballast

Abstract

This study aims to examine the factors that affect the behavioral intention of the use behavior of echocardiography systems using approaches Unified Theory of Acceptance and Use of Technology (UTAUT).Data obtained from 51 respondents perceptions of medical personnel as users of the system echocardiography of several hospitals in Banjarmasin. Methods of analysis using multiple linear regression and partial correlation. The results showed that the performance expectancy, effort expectancy and social factor influence the behavioral intention of echocardiography system and facilitating conditions  and  behavioral intention affects the use behavior echocardiography system. The age factor has a moderating effect on the relationship between performance expectancy with a behavioral intention, facility condition factor with the use of behavior, the age factor does not have a moderating effect on the relationship between effort expectancy, social factors with the behavioral intention. Experience factor have moderating effects on the relationship between effort expectancy with behavioral intention, facilitating conditions with use behavior, the experience factor has no moderating effect on the relationship between social influence with behavioral intention. Voluntariness of use have moderating effects on the relationship between social influence with  behavioral intention of echocardiography system.Keywords: System, Echocardiography, UTAUT

Abstract

Indonesian people are very familiar with bamboo. Bamboo is often used as a building material. It has many advantages, the price is relatively cheap compared to other building materials, and easy to found the bamboo around settlements. Utilization of the bamboo will produce greater bamboo waste, example leftover building materials, waste of making the crafts etc. So far, the waste of bamboo only released into the environment, the material is a category of biomass that can be used as raw material in the producing of briquettes. With consideration as alternative energy, basic materials waste briquettes using bamboo can reduce environmental pollution and also have economic value.The making process of bamboo briquette is preceded by pyrolysis for 5 hours with temperatures about 5000C. The briquette is cylindrical with a diameter of 23 mm, height 7 cm and pressure about 75g/cm2 and dry in the sun for 6 hour. This briquette using waste rice as a adhesive with variety is 30; 35; 40; 45% of the weight of briquettes. Based on the research results, the best briquettes obtained by variation of adhesive 30%, with a water content of 5.34%, 8.2% ash content, 15.6% volatile matter, the firing rate 0.02 g/sec, 70.73% spesific of briquette carbon content, and calorific value of 6709.50 cal/g. Based on these results bamboo briquette is in compliance with the quality required by the SNI, except on the value of volatile matter.

In a corporate organization or agency CIO is a title that serves to integrate IT systems management aspects in order to align with the objectives to be achieved. CIO is important part in the success of an organization, company or agency. CIO role and inovated integrated or make the information be more efficient and rewarding better. CIO role are aspects of information, risk management, knowledge management, and investment so that drive efficiency, transparency, business process adjustment or reform of government bureaucracy. Mental Hospital Prof. dr. Soerojo Magelang (RSJS) as a health organization under the Directorate General for Development Efforts Ministry of Health, in performing daily activities and activities that the whole process was highly dependent on the availability of quality information. The ability to retrieve, compile, store, select, disseminate and circulate information from one place to another will greatly affect the level of organizational performance.In this research made the institutional model, CIO roles and competencies that can be applied in RSJS. Model made further tested with Delphi Method. Iteration is done in 3 times. Each iterations, the answers were analyzed to be the next model and tested again. Similarly, to obtain the final model, and the final model was analyzed based on sources from the existing literature for the resulting model will be recommended.
