Abstract

 Tutoring institution is an organization which focuses in education. The objective of this institution is improving the quality of learning of all students to achieve the desired target. The operational activities of this institution consist of registration, scheduling, evaluation, and administration supporters. It will be less effective if the processes are done manually. Therefore, many institutions are starting to restructure the model of information systems to support the company’s operations. This study describes about designing an information system model using object oriented approach based on the methodology introduced by Satzinger, where each phase is represented by using UML diagrams. The result achieved in this research is to produce a general model of information systems in supporting the operations of a tutoring institution. Designing an information system that is compatible with business processes can maximize the company's operations to run efficiently and effectively so as provides a competitive advantage from its competitors.

Abstract

The aim of this research is to design a database model which is conceptual and logical for a 24-hour clinic. The methods used in this research are the data collection through literature studies, surveys, and interviews to the clinic management to get a description of the business processes implemented at a 24-hour clinic. Then we use the conceptual database design method which identifies important entities, relationships entities, and existing attributes. After that, we create a database logical model which represents the clinical database 24 hours. From that, the model is expected to be a logical database model for further development into a clinical application 24 hours to improve the health services to the public.

Abstract

In promoting the use of Information and Communication Technology (ICT) in order to improve efficiency and effectiveness of government service institutions, the Government of Indonesia issued Presidential Instruction No. 3 of 2003 on e-Government. The directive requested that all government institutions in Indonesia should take advantage of ICT to improve public services. In line with this, the Ministry of Agriculture has launched several efforts to support the implementation of Presidential Instruction. One of these efforts is the implementation of the Web Site Competition between Work units under the Ministry. The contest has been held since 2004. The participants were grouped into three categories: 1. Directorate General / Agency 2. Provincial Agricultural Office 3. District Agriculture Office. To carry out the website competition, the Ministry of Agriculture has appointed a five person jury. To evaluate whether there are significant differences between the judges in scoring on the website which was considered and the factors that may affect the assessment, some analysis has been done. The variables included in the analysis was judge scores, level of institution, previous achievements in the competition, the location of both institutions in Java and outside Java. The statistical methods used in the analysis are Multiple Linear Regression and Variance Analysis. The analysis uses data from the Ministry of Agriculture Web Site Competition 2008-2010.

Abstract

Producing quality products to match customer expectations is an important thing that needs to be done by every company that produces any product, to gain public appreciation and sell their products on the market. Therefore companies need to have a strong commitment in improving and maintaining product quality. The study related to product quality of flat sheets of fiber cement or more commonly known as versaboard produced by PT. Bakrie Building Industries show that there are 9 (nine) types of defects that can degrade the quality of production. Most dominant defects occured on 3 (three) versaboard products, the crack (2.03%), broken end (0.80%) and side trim (0.35%) during observation. Sigma level of products is obtained at 4:16 at a cost saving of due to defects of Rp.14.645.600, 00. Defects that occur tend to be caused by methods, people, machines, and materials used. Efforts to reduce the level of defects are done by making the SOP of the break-up method, and manufacture of cutter flow diagram. REBA score calculation results (Rapid Entire Body Assessment) in the removal and break-up reduction is obtained at 8 with a high level of risk should lead to improving the position of the operator using the Rapid Entire Body Assessment (Reba) so that operators can work more carefully and responsibly..

Abstract

Green Base transceiver station (BTS) or known as remote BTS is a special BTS with IP technology-based that has a small capacity and takes low power consumption with standard features suitable for use in rural areas. BTS utilizes 100% solar energy as a source of energy. The infrastructure Green BTS is composed of high-tech devices which is able to save energy, environmentally friendly, small and lightweight. The high rate service calls and SMS on green BTS is caused by the absence of competition telecom operators at a site. The solution to this  problem needs to be done with system dynamics modeling approach with the aim to establish causality (cause and effect) between the variables. The standard target of model pattern which has been changed on system dynamics can be used to demonstrate the behavior of the model between the number of subscribers, the availability of network capacity and ARPU (average revenue per user) on the Green BTS site. On the changed standard target model, the actual revenue is placed as the actual event, the target revenue is as a target; the difference between the actual and target revenue is as gap, gap changes are as the pressure on the target and the corrective action taken against revenue as a corrective action. Based on simulation results, the standard model change targets can be developed by adding two negative loops (balancing loop) as an alternative solution towards the achievement of revenue targets that have been set.
