Abstract

The objective of this research is to develop a web-based expert system for early detection towards characters of investment of people who will invest immediately on their productive ages. The development of this application is encompassing four primary activities in developing an expert system, namely: knowledgeacquisition, knowledge representation, knowledge inferencing, and knowledge transfering. Knowledge acquisition is a process of acquisition or transfering knowledge or expertise of an expert through a knowledge engineer. Knowledge representation is a process of transfering knowledge into a computer based system. Knowledge inferencing is a reasoning process performed by an expert system to draw a conclusion or a final result. The reasoning process applies a forward-chaining method. Knowledge transfering is a process of transfering knowledge from an expert system to a user (non-expert one) through a user interface of the expert system. This expert system has been tested to about 300 users. This simple system generally runs quite well although there are still some weakness to refine in the further research.

Abstract

The development of RFID technology (Radio Frequency Identification) offers some advantages, especially in goods distribution, supply chain and logistics. This technology works by putting a chip on an item as a replacement for barcodes that are widely used today. With the RFID technology, the process of goodsidentification becomes very easy and fast. Therefore, some large companies have started implementing and trust the system, especially the supermarket retailers although there are still some problems encountered in the application of this system, related to issues of privacy and data integrity problems. This paper discusses how RFID works and the impacts to the company related to profits and problems encountered during the application of this system.

Abstract

One way to increase profitability internally in PT Mangul Jaya - Bekasi is decreasing any costs produced from poor product quality by producing shoes with good quality. This study uses the DMAIC (define, measure, analyze, improve, control) method as a measuring tool. DMAIC is a quality improvement method that directly solves any problems related to the quality of a product even the primary cause of it. From the results of the study it is concluded that at the phase “define” shoes type Cheetah is the most problematic. Furthermore, on phase “measurement” it is identified that the Cp value of the Cheetah is below 1 which means that the process capability is low. After passing through the three sequencing steps (analyze, improve and control), finally this research is able to reduce the defects that occur in the shoes type Cheetah.

Abstract

Spatial autocorrelation is a spatial analysis to determine the relationship pattern or correlation among some locations (observation). On the poverty case of East Java, this method will provide important information for analyze the relationship of poverty characteristics in each district or cities. Therefore, in this research performed spatial autocorrelation analysis on the data of East Java’s poverty. The method used is moran's I test and Local Indicator of Spatial Autocorrelation (LISA). The analysis showed that by the moran's I test, there is spatial autocorrelation found in the percentage of poor people amount in East Java, both in 2006 and 2007. While by LISA, obtained the conclusion that there is a significant grouping of district or cities.

Abstract

In any city development, it is important to urge people to be involved in so that the development can be valued as much as possible. Model of involvement is certainly diverse, such as 'one-way involvement' in which people tend to just listen, and 'two-way involvement' where the people to participate to make a decision. This paper observes how the public participated in the arrangement of slum area undertaken by the Government. Although there has been community involvement in this activity, there are still any limitations.

Abstract

The application of knowledge management on the Internet keeps growing. This is due to the Internet that offers new opportunities to use the knowledge assets, define the type of new knowledge assets, and spread even outside the organization. The emerging social media is enabling internet-based knowledge sharing system. Social media itself is nothing new, but now has undergone many changes that allow for much interactive interaction and much greater number of users. The results showed that knowledge management and social media contain almost the same components. This allows the role of social media on the application of knowledge management, such as collaboration tools accompanied by a clear business purpose.

Abstract

This research is a continuation of previous research, which is a development of academic information systems for higher education with database reporting of EPSBED to DIKTI. Researchers will continue to develop the design using use case diagrams and rich picture diagrams. The design is useful to help the team of developers in building the application especially in coding process. The method used is studying the results of previous research then developing the design of use case diagrams and finally making the rich picture diagrams. The results of this research is a process design of a university in use case diagrams and rich picture diagrams. This research found that an academic information systems can be designed with use case diagrams and rich picture diagrams to facilitate coding process. This design is expected to be developed into a ready-use application that can be utilized in universities.

Abstract

This study aims to examine the application of ratio estimators on a sampling method by taking the case of estimating the ratio of critical land of every county around Jratun watershed. Through the estimation, a general description of critical land deployment for each region (county) can be obtained. In addition, the estimator of hose/interval is also determined for the ratio with the real level of 0.05. The simple random sampling method is used in conducting the estimation of ratio of the critical land to the total land area. Theestimation results show that the ratio of the critical land to the total area for 19 districts reaches 23.72%.

Abstract

Currently the use of liquefied petroleum gas is urgently needed as a substituting fuel in both household sector and industrial sector. The Government’s program namely the conversion of kerosene to LPG encouraged people who still use kerosene as a fuel to switch to LPG. There are some public complaints about the quality of the conversion product such as conflagration that occurs frequently caused by the explosion of LPG tube. Application of SNI LPG tube related to the energy conversion program is expected to give a safer condition to the users. This study is conducted by analyzing the quality requirement of LPG tube products according to SNI as well as to identify the fulfillment of LPG tube products.
