Abstract

Materialized Query Table (MQT) stores data from frequently used queries so that users can get data without having to re-compute. This can improve system performance by reducing the cost of queries. The data in the MQT must be updated periodically it will not become obsolete when some change being made in the parent table. There are 2 (two) kinds of commonly used update mechanisms, namely full refresh and incremental refresh. Full refresh recompiles all data from the parent table. While incremental refresh only process data that being changed by utilizing staging table. The staging table stores the data changes (delta) in the parent table so that incremental refresh can be performed. This study simulates and compares the performance of full refresh with incremental refresh to know the impact of both of the query execution time and resource usage (I/O and CPU). The data used are original data derived from previous research and dummy data generated by system to support this research. Test results show that incremental refresh increases performance by more than 10 times at query execution time and increases more than 50 times on resource usage compared to full refresh.

Abstract

Printed Circuit Board (PCB) is one of the features available on the SFE-Electronics website. Recommended PCB ordering is expected to meet the needs of PCB buyers who can be ordered according to the needs of the buyer. However, in its application the PCB ordering feature has not been able to increase PCB bookings through the website. Of the total PCB sales only 6 out of 120 buyers make PCB order through the website. This study focuses on the evaluation and preparation of user interface design recommendations by adapting the Human-Centered Design (HCD) method. HCD is an approach method that incorporates a user's view of a system into the software development process to achieve a system that can be used as needed. Research begins with an initial evaluation conducted by identifying and analyzing stakeholders and understanding the user context and exploring the constraints of using PCB bookings. The second stage is to design the results of the first evaluation in which the results of the design is done further evaluation to find constraints on the design results. From the first evaluation stage found three obstacles on ordering PCB that is on aspect of user expectation, aspect of making of online form as ordering facility and participant response aspect. Nine pages of the design were made on the basis of the first evaluation results and from those nine outcomes were further evaluations that found obstacles on the PCB order page and automatic calculations which were then repeated.

Abstract

Scheduling is one of the computational problems that is not easily solved. For solving it must be prepared systematically, by maximizing resources and time available effectively and efficiently. Scheduling problems can occur in various fields, including education. SMA Negeri 6 Surabaya is one of the high schools in Surabaya that has problems finding the right time slot with a limited number of teachers and there are some constraints that must be met in the scheduling of subjects. One method that can be used in the scheduling of subjects is to use genetic algorithm hybridization and simulated annealing (GA-SA) because GA has the weakness of early convergence and possibly stuck in local optimum, then SA is given as a solution to cover the weakness of GA and able to survive on a local optimum. The algorithm hybridization process is done with the first step in GA using chromosome representation of integer numbers, one-cut point crossover, reciprocal exchange mutation, and elitism selection. In the second step, a simulated annealing process is done using neighborhood move. The results given are scheduling the subjects by meeting the existing constraints. Based on the research, the optimum parameters are the number of generation 270, the population 90, the combination of cr and mr are 0.3 and 0.7 with the average fitness value of 0.999000.

Abstract

Zakat can be one way done in effort to increase social welfare and was one of the important role in economic community empowerment. Other benefits of zakat is to help reduce poverty and also can reduce the social inequality in society. But the problems encountered by these institutions in distributing zakat is the inaccuracy in choosing a recipient of zakat. The inaccuracy in choosing a zakat recipient occurs because the zakat management agency still provides subjective assessments. It is causing loss to the people who are more eligible to receive the zakat. The SAW (Simple Additive Weighting) is one of the methods in decision support system that can be used to create a system that can determine the recipient of zakat. There are 4 criteria used in determining zakat recipient in this research, there are family status, family income, total dependents and value report card. Based on the accuracy testing that has been done by using 60 test data, obtained the best accuracy of 90%. The SAW method can be applied properly in determining the recipient of zakat.
