Abstract

In a project implementation, the project implementer wants the project completed on time as efficient as possible while the produced quality is in accordance with the initial plan. Therefore, in order to meet the requirements for controlling process and to minimize any deviations that can occur during the project, the earned value method is considered accurate. The aim of this study was to identify the final result of the project which will be achieved in the aspect of cost (whether the project experience gains, losses, or within budget) and time (whether the project is delayed, ended early, or on time as scheduled). The study was conducted on the 4th, 8th, 12th, 16th, and 20th weeks by using the earned value. Earned Value Method, or often called the Concept of Earned Value, is the concept of calculating project costs in accordance with the budget and the scope of job which have been completed or implemented (budgeted cost of works performed). This method combines the cost, schedule, and work performance of a project. Therefore, this method is considered effective in monitoring and controlling project activities.

Abstract

The growth in the implementation of quality management system standard as an instrument to win global market competition and to improve product and service quality has affected not only manufacturing industries but also construction industries. One of the standards that is most widely implemented by companies or organizations in quality management system may be the ISO 9000. It should be noted that the ISO 9000 is not a standard for products or services, but it is a standard for quality management system employed in their production process. The objective of this research is to study the implementation of the ISO 9000 standard by the PT. Wijaya Karya Beton that has adopted the ISO 9000 for its quality management system standard. In addition, the criteria for evaluating its performance have also been identified. This criterion includes written procedure and its consistent implementation, as well as the measurement of the implementation result of its operation process flow and working procedures. This research was carried out by means of performance measurement, i.e. qualitatively by employing questionnaire, scoring and measurement on productivity and targeted quality achievement such as rework rate and reject rate. The data were collected by observation, extraction from the internal and external quality audit report, as well as daily-, weekly- and monthly reports on the pile production. The effect of company’s performance that employs the ISO 9000 standard (qualitative measurement) on the productivity, rework rate and reject rate (quantitative measurement) were analysed using Pearson’s Product Moment correlation analysis technique. The result reveals that the qualitative measurement resulted in continuous performance improvement, so did the quantitative measurement. It showed that these two measurement methods tends to be in a good agreement. A general conclusion that can be drawn is that the ISO 9000 has been properly implemented in the PT. Wijaya Karya Beton.

Abstract

Al Asel Mosque is one of the mosques in Banyumeneng Hamlet, Banyuraden, Gamping, Sleman, DIY, which was established in 1985. Over time the number of worshipers has increased. The current size of the mosque is no longer sufficient to accommodate people who want to worship, especially Friday prayers and Tarawih prayers in the month of Ramadhan, so that they often spill out to the courtyard of the mosque. Problems arise when it starts to enter the rainy season. The mosque yard covering an area of 12x12 m2 which has been covered by concrete block and marked for prayer can not be used anymore. As a result, prayers had to crowd within the mosque and on the porch, even forced to pray on the terrace of the kindergarten room. This of course reduces the solemnity during worship. The committee of Al Asel Mosque planned to build a roof of the mosque courtyard so that the prayers can pray on the courtyard during rain. The purpose of this activity is to help the committee of Al Asel Mosque realize the roof structure of the mosque's yard covering an area of 12x12m2. The method of activities carried out include designing the roof structure and supervision during the construction process in a few weeks. The design process produced documents consisting of design drawings and budget plans. After the completion of the mosque roof construction, the capacity of pilgrims increased and it is expected that prayers would be more solemn during worship.
