Abstract

Water purification is typically carried out using chemical coagulants like Tewes. localname for Aluminum sulfate. In many parts of the world experts are looking into coagulantmaterials derived from plants. Among many of them is the Moringa seeds. Moringa seedscontain water-soluble proteins, when crushed and dissolved in water it will form a positivelycharged solution. Electrophoreses Test proved that positively charged solution were alsoresulted from the use of Salak seeds and Papaya seed. The purpose of this study was toanalyze the differences in coagulation using Moringa (Moringa oleifera), Salak (Salaccazalacca), and Papaya seeds (Carica Papaya).The study was performed in a quasi-experimental set up exercising a pretest-posttestdesign. The object for the study was water sample taken from a river used by the communityin kecamatan Krembung for their water source. As much as 1000 ml of river water was used ineach test run. Test containers were treated with natural coagulants. Coagulant materials usedin the tests were Tawas powder, Moringa, Salak, and Papaya seeds at a dose-series of 50 ppmto 1000 ppm. The resulted data were analyzed using Kruskal - Wallis Test.There was a significant difference with regard to optimal dose of the natural coagulantsas well as the percentage of turbidity reduction. The optimal dose for Moringa seeds was 130ppm with a percentage of reduction at 97,3% that reduced turbidity down to 2.7 NTU. Theoptimal dose for Salak seeds was 100 ppm that resulted in a percentage reduction of 89,2%and reduced the turbidity down to 10.9 NTU. The optimal dose for Papaya seeds was 50 ppmwith a percentage of decline at 83,4% reducing the turbidity down to 16,7 NTU. Moringaseeds coagulant has maximum turbidity reducing capability, while the other two naturalcoagulants, Salak and Papaya seeds, were not in their maximum levels of turbidity reducingcapabilities.At a dose of 200 ppm Moringa seeds exhibited a greater ability as a coagulant inlowering water turbidity compared to the other natural coagulants, Salak seeds at a dose of100 ppm and Papaya seeds at a dose of 50 ppm. The study concluded that Moringa seeds canbe applied as a substitute for chemical coagulants provided they are used within 1 x 24 hours.Key Words : Turbidity and Coagulant

Abstract

Alam Jaya Workshop is an individual company engaged in services or repairs of four-wheeled vehicles located on 32 Tidore Street. In processing the data, both sales data, customer data, goods data, purchase data and reports on Alam Jaya Workshop are still not well computerized. The data processing system used in Alam Jaya Workshop is currently still manual, where the service data search process is slow and difficult because the data is not well coordinated, making reports slow if the report is needed immediately, the accuracy of the data is not guaranteed. All these problems arise because of the lack of good organization in processing data and in making reports, it is still recorded in the agenda book, resulting in slow performance. Therefore, this study aims to provide a solution to the problems that occur by offering sales information and maintenance service along with purchasing system using Unified Modeling Language (UML) to design the system modeling such as Use Case Diagram, Activity Diagram and Class Diagram as well PHP programming language, MySQL DBMS with Adobe DreamweaverCS5 editor and waterfall system development method. There are several stages in doing this research that is problem identification, literature study, data collection, data analysis, system design and report writing. The result of this study is a system that can provide effectiveness and efficiency in processing data at Alam Jaya Workshop.

The game theory is a mathematics model used in a conflict or competition among various interests that meet each other as competitors. Basically, the theory is a study of strategy interaction among the players to determine the best strategy and the obtained score. One of basic elements of the game theory is solving every case of the game theory where the pay-off matrix is shown in a game matrix table. The data of game between Shopee and Tokopedia obtained the optimum score which was 2.4443. Shopee and Bukalapak obtained the optimum score which was 6. Meanwhile, Tokopedia and Bukalapak obtained the optimum score which was 8.9925. In the Shopee, Tokopedia, and Bukalapak competition, the Nash equilibrium point is located at the point () with a pay off value (64,56,43), Shopee with a discount voucher strategy (), Tokopedia with a Product strategy (), and Bukalapak with a promotion strategy () which is the optimal strategy for each player.
