Abstract

Education is very important and one of the keys of the progress of a country. Basic education or elementary school is the first stage of a long journey for a student in taking his or her education. The more parents has awareness in the importance of an education so the more the parents will enroll their children to study in school. Although the number of schools in a certain place is already considered enough, admission of new students still become a unique phenomenon because number of prospective new students entering school is huge but the admission method still uses manual techniques. Whether using a test or previous level report book, the rank and decision making about the acceptance of the students is still done manually. It can also provide opportunities for certain parties to commit fraud in the admission selection from subjective point of view (outside of the fixed criteria) which makes incorrect calculation and grading so the results are not properly valid. This research would apply the rules that is formed from the decision trees on admission of new students selection process at SDIT An-Najah Jatinom Klaten. A decision tree consists of a set of rules for dividing a heterogeneous population into smaller parts, and more homogeneous with noticing to the goal variables. C4.5 algorithm is one of the algorithms used to form a decision tree. The purpose of this research is to apply the rules that are formed from the C4.5 decision tree algorithm in admission of new students selection process. The registration (log) is expected to be more structured through this system so operator can easily and quickly process the calculation and ranking the prospective new student. Service becomes more rapid, accurate, effective, and efficient in terms of time and place because the piled print files (takes place and time) can be concise (stored in the database). The results shows that the system is able to provide recommendations for the admission process based on the criteria and history that have ever happened. Based on sample data of 100 data among several criterias (religion, age, the average time from the each student’ place to the school, parents income per month, number of siblings)is is found that religious criteria have the highest gain value in the calculation of the initial node, ie by 0.367877. Finnaly, this system has been running correctly and can help the school admission committee in the selection of new candidate students.

Abstract

Carter model is a quality service dimension developed by Parasuraman et al to measures service quality which covers Assurance, Reliability, Tangible, Empathy and Responsiveness. The research subject was a syariah company, therefore Compliance dimension is exercised. The instruments applied to measure service quality is questioner in Linkert scale and distributed to costumer. Due to the subjectivity contained in received questioner answers, Fuzzy is utilized to transform it into a quantitative value as an input for Servqual. Thus, servqual is applied to calculate the gap between customer expectations and perceptions of the service offered. By practicing Cartesian diagram, the attributes need to be addressed were attained. The largest gap is in the attribute called “Promised service time” in Reliability dimension with 0.556.

Abstract

Load demand of electric power supply varies from hour to hour in a day . It is inefficient to operate all power plants along day under various load variation. A power plant scheduling system is needed to minimize total operation cost of the power plants and in order to meet the amount of power needed by the load. This research proposes a method on power plant scheduling based on genetic algorithm. Total operation cost is used as objective function and the amount of power needed by the load is applied as a constraint. Population of chromosome in genetic algorithm represent candidates of alternative schedule of power plant operation. The best chromosome is the schedule with minimum cost and which meets the constraint. This method was applied to schedule the power plant system of Sumatera Bagian Tengah. Optimization was done in every 30 minutes. Based on test and analysis, this method results in more efficient cost, compared to manual operation of power plant systems.

Abstract

Data of traffic accidents in Indonesia reveal high rate of traffic incidence. Lack of discipline, low driving skill, poor knowledge of traffic rules of drivers are at high risk. Education on traffic rules can be obtained easily from both printed and electronic media. Large amount of information on safety driving, however, has not significantly reduced traffic accident rate. Some types of education on safety driving available at present may not be effective for would-be drivers. The objective of the study was to identify the effective education in safety driving on the knowledge of perspective drivers when encountering traffic conflict. The study was conducted on 30 respondents aged 15-17 yeras, who were classified into 3 groups: 10 respondents used visual texts, 10 respondents used visual pictures, and 10 respondents used Audio Visual (an instructor). All respondents took pre-test and post-test. The result showed the type of education influenced would-be drivers' comprehension. Visual pictures and audio visual (an instructor) were the most effective types of education on safety driving for perspective drivers.

Abstract

        Minimal Linux system is commonly used for special systems like router, gateway, Linux installer and diskless Linux system. Minimal Linux system is a Linux system that use a few facilities of all Linux capabilities. Mandrake Linux, as one of Linux distribution is able to perform minimal Linux system.         RAM is a computer resource that especially used as main memory. A  part of RAM’s function can be changed into disk called RAM disk. This RAM disk can be used to run the Linux system. This paper explains how the Mandrake Linux system can be run in a RAM disk. The RAM disk which is used to run Linux system is loaded at the moment of initialization of Linux system. This RAM disk is called initial RAM disk (initrd). The Linux kernel which support initrd and a boot loader are needed to develop this system. The initrd file system that content Linux root system is created in this research. This initrd file is loaded into the RAM disk  using a boot loader.        This experiment shows that the Linux system can be run in the RAM disk. The Linux system that can be run is minimal Linux system because of the RAM disk capacity limitation.Keywords : minimal Linux, RAM disk, initrd

Abstract

The exhaust gases from automobile engines and industrial boilers contain mainly oxides of carbon (CO and CO2), oxides of nitrogen (NOx), hydrocarbons (HC), sulphur dioxide (SO2), particulates and soot. One of the most urgent problems is removal of NOx, typically produced during high-temperature combustion and contribute to formation of smog and ground-level ozone by reacting with hydrocarbons in presence of sunlight. Preparation, and modification of CuO / natural zeolite as well as their characterizations had been carried out. The aim of this research is to prepare the best characters catalyst for selective catalytic reduction of NOx. The CuO / natural zeolite was prepared by mechanically mixing of 100 g of natural zeolite, which it has been heated at 400oC, with CuNO3.3H2O powder, The weight ratio of the mixture was 2.5 and 5% (w/w). The mixture was then calcined at 400oC for 6 hours. The calcined product was characterized using X-Ray Diffractometry, X-Ray Fluorescence analysis and Gas Sorption Analysis methods to determine its physicochemical properties changes caused by mixing and calcination. The characterization results showed that dispertion of CuNO3.3H2O on zeolite resulted in the increasing of copper concentration on CuO / natural zeolite. The concentration of Cu on natural zeolite was found to be 0.15% (w/w), meanwhile on CuO / natural zeolite was 2.29% (w/w). From X-Ray Diffractometry analysis result no information was found that CuO was dipersed on natural zeolite. It was caused by overlapping of the reflections of zeolite with reflections of CuO. On the otherhand, the gas sorption analysis result exhibited that the dispersion of CuO on zeolite resulted in the decreasing of total pore volume as well as specific surface area of the natural zeolite. The specific surface areas of natural zeolite and CuO / natural zeolite were 228,1 and 172,1 m2/g, respectively, meanwhile the total pore volumes of natural zeolite and CuO / natural zeolite were 0.2316 and 0.2108 m3/g
