Abstract

This paper examines batch scheduling problem that has batching and sequencing in single formulation for multiple-item case. The first step is to develop a model for single item single resource discussed in Zahedi (2008). The model determined batch sizes and their schedule simultaneously in single item case. This paper develops the model and algorithm for multiple-item case. The model functions to minimize total actual flow times. An algorithm for the model is developed using a relaxation of the binary constraints. The binary values for the decision variables are obtained from steps provided in algorithm. A numerical experience showing characteristics of this problem is presented.

Abstract

Bushing is one of the eminent product of PT Indokarlo Mighty. The company requires some suppliers of iron cutting services to continue providing high qualified raw materials. The quality is the accuracy of the intended length of the products which is able to meet the requirements of the requested length. The purpose of this study is to determine what factors caused the defect on the length of the products. In addition, it is objected to provide appropriate solutions to eliminate to the factors, so that the number of defected products can be reduced. This study uses the methodology of Six Sigma improvement models Define-Measure-Analyze-Improve-Control (DMAIC) to make improvements in the quality of services provided by PT Argatama Multi Agung, while the improvement phase uses Design of Experiment (DOE) to find the machine configuration that can produce the best quality products. A significant increase in sigma is obtained from the conducted research.

Abstract

Besides opening new land to the hilly terrain, reclamation of beach and other watery land is one of the alternatives of residential land compliance which is pretty much applied. However, the reclamation work often encounteres some obstacles, such as the soft subgrade with a low carrying capacity and the possibility for consolidation reduction which is large and long and high sea waves that could potentially cause abrasion during both construction and after construction. The use of geosynthetic materials as an alternative material supporting the reclamation work in Indonesia is still limited. The project owner and executives tend to use conventional methods though the use of geosynthetic can provide benefits and ease of implementation. Some of the advantages of using geosynthetic materials in reclamation work with soft soil foundation is a faster execution of the work, loss reduction of embankment material into the soft subgrade, and lower maintenance costs. This paper discusses geosynthetic products as well as its application to the reclamation work that comes with examples of projects that have been or are being carried out and in Indonesia.

Abstract

This article contains several things to be controlled by a Project Manager in order to be able to develop a software engineering project plan. The development methodology begins with survey, analysis and engineering in software planning. Establishing a good project team structure is as important as selecting team members who are also experts in their field. Perceiving that the construction and implementation of information technology-based systems are executed using a project management approach, the project manager is then the most responsible officer for the team performance. The project Manager will lead his team to planning and developing information technology projects in accordance with their intended target. There are three fields that must be considered in an information system project, namely: information systems, information technology, and information management.

Abstract

High increment of information system needs for company goes in line with the high demands of increasingly competitive and rivalry of industry. Corporate investment needs automatically increase to meet the demanding needs of this system. New developments in systems and technology can not be ignored by companies because it gives a very high economic boost in the competition. On the other hand, in line with the development of information systems is the development of Open Source applications as a cheaper alternative for enterprise use. With so many alternative of Open Sources requires companies to be more observant of selecting the best applications that meet the company needs and can be quickly implemented. This study presents the best approaches to select the best Open Source applications for companies, such as literature review, implementation and evaluation of e-learning Open Source application.

Abstract

One of the required resources in IT development projects is the human resource. Human resources has a role and an enormous influence on the process and the success of IT projects. By conducting a literature review and analysis of the factors of human resources, it is obtained the factors that influence the operation of IT projects. The factors may include factors that can be absorbed and factors that cannot be absorbed. Weaknesses in human resources are weaknesses that can be pressed or elaborated in such a way so as not to interfere the performance of the project. Performance of the project is one aspect that determines the quality of a project. The more positive the value of the performance of the project, the more positive the value of the quality of a project.

Abstract

Tight competition in the broadband industry has forced the provider to have a good product propotition and strategy in the market, including market segmentation and type of services delivered based on customer’s expextation and intention to buy. This research aims to make a product proposition based on two major criteries in fixed broadband service, which are speed and price of the product, by looking into the competition in existing market (competitor’s product). As many players in Indonesia have created very tight situation, the will be launched product should have an attractive matter or differentiation in order to compete and get a “buy in” of the customer. In the research, some analysis was conducted across all the propositions by spreading questionnaires to respondents in urban area especially in Jakarta and Bandung, thus the provider can create product with an appropriate specifications to answer the needs of customers on their affordable price to buy. Some close-ended questions in the questionairres were scaled and performed by basic statistical approach methods. The result shows that product with affordable price is still become the choice of respondents in each segment (low, medium and high income). Price list per speed which is fitted to any segments is also suggested in this research. The result of the research can also be used to develop the product as a differentiation to be the choices and preferencesof customers.
