Abstract

Zakat management in Indonesia is one of the interesting things to be studied in order to alleviate poverty and improve the welfare of the community, this can be seen from the potential IDR 217 trillion national charity but only reached about IDR 1.5 trillion. Factors affecting the collection of zakat in Indonesia is the level of trust muzaki against Zakat Organisation (OPZ) that in this study is a Zakat Collector Unit (UPZ), muzaki option to distribute zakat directly to mustahik individually, lack of knowledge of the mechanisms muzaki charity, and the lack of muzaki knowledge of the existence of UPZ. To address this problem, we need an information system that can organize management processes that occur in the management of UPZ-based charity, especially mosque-based UPZ, the mosque as a base because of it religious activities in the community. The method used is the analysis to direct UPZ location and design of the interface, rules, and prototype. From this study produced an Integrated UPZ and BAZNAS Tasikmalaya City Information Systems using web technologies.

Abstract

In dividing assignment, manager is not recommended to make decision with only intuition and experience, but must be based on facts. The problem is the fact-based decisions will be long or difficult to do with conventional ways. Therefore, Decision Support Systems (DSS) is needed. In DSS, providing advice should be more than one option so that manager can choose the bestoption. However, commercial applications for assignment cases in operation research can only provide one optimal solution. Besides, commercial applications cannot handle assessment process that has specific criteria, such as Microsoft Excel and WinQSB. The theory used in thisapplication was assignment method. The study implementation used waterfall model in System Development Life Cycle method. The study results show that the application can produce optimal solutions more than one option if possible so that it repairs the lack of commercial applications in operation research. Thisapplication can also give solution for any assignments accurately and comprehensively because it can handle assignment assessment that has spesific criteria.

Abstract

Cervical cancer has became the common women disease in the world. Mostly, cervical cancer has been already known lately, because it is very dificult to detect this in early stage. In this work, a computer based software using Learning Vector Quantization (LVQ) has been designed as the early cervical cancer detection aid tool. There are six methods before the detection is performed, namely preprocessing, contrast stretching, median filtering, morphology operation, image segmentation, and Discrete Cosine Transform based feature extraction. In tihis work, 73 cervical cell images that consist of 50 normal images and 23 cancer images are used. 35 normal images and 14 cancer images are used to train the LVQ. Then, 23 normal images and 9 cancer images are used in the testing process. Our results show 88,89 % cancer image can be detected correctly (sensitivity), 100 % normal image can be detected corerctly (specificity), and 95,83 % for overall detection (accuracy).

Abstract

A problem that often encountered in sources voltage especially DC (Direct Current) voltage sources are far below the working voltage levels that are generally used in residential electrical grid system. To handling the problems of the DC voltage source, one way that can be taken is to implement a DC voltage converter circuit or DC-DC Converter. In this paper, a series of isolated type DC-DC Converters, namely Push-Pull Converter, is being promoted. The Selection of Push-Pull Converter based on reliability and quality of generated power among others, ease of applicability and the most important is the robustness of the interference that may occur. The system is controlled by a simple linear controller, such as Proportional Integral (PI) controller or Integral Proportional (IP) controller. System’s stability is also tested using Bode plots. From simulation results and stability analysis, it can be conclude that the Push-Pull converter circuit resists against disturbance.

Abstract

Research has been conducted to study the Windbelt as electrical generators. This research aims to study the aspect ratio of the ribbon to the ribbon flutter, the influence of stress to flutter frequency, the influence of windspeed to induction voltage, the effect of wind speed on the amplitude, wind speed relationship to flutter frequency, wind speed relationship to the power of wind belt . The results show that the higger aspect ratio required lower wind speed to flutter. Test results wind belt frequency with a fixed force of 5.88 N and wind speed 3m / s to 5.5 m / s indicates the value of fixed frequency ( 111 ± 0.2 ) Hz . This fact shows the standing wave by fluttering ribbon following the Melde’s law. Amplitude ribbons flutter initially increases with increasing wind speed, but eventually almost constant amplitude. This occurs because the elastic force who against the aerodynamic force was proportional with amplitude, so that the amplitude is fixed. Wind belt electric voltage generated increases with increasing wind speed. Wind belt electrical power is directly proportional to the wind speed.
