All technology platforms now use multimedia elements as GUI Interface because it makes it much easier for users to control it. The introduction of cultural customs such as Indonesian traditional dances and songs is critical so that it remains sustainable and is not undermined by foreign influences. A new and appropriate media is needed to socialize it, amicable and fun media for young children. Application of Application Programming Interface (API) in Indonesian death dance and song applications makes it easier to change data so that data flow mobility can be faster to change. The results of the research show that the implementation of API in the application has better effectiveness. and the white box test results show that the coding system can run according to function.</p> Bayu Priyatna Aprilia Hananto Copyright (c) 2020 SYSTEMATICS 2020-08-01 2020-08-01 2 2 47 57 10.35706/sys.v2i2.3481 Design and Development of Automation System for Measurement of Flow Nozzle Robot Spray Based on Programmable Logic Controller and Human Machine Interface at PT ADM Casting Plant <p>The spray is one of the important processes in the metal smelting industry that uses die casting machines to make aluminium products. This spraying process serves to prevent the problem of stamps (products attached to the dies/mold) due to overheating (overheating) on ​​the surface of the dies. The main device in this spraying process is the nozzle that is driven by a coil from the solenoid valve. To maintain the quality of the output spray to remain standard, routine maintenance is carried out manually by two operators. Operator one is outside the machine area to see the digital flow sensor display and the second operator is inside the machine area to operate the solenoid valve nozzle spray. Communication between operators plays an important role when carrying out the process of flow spray measurement. This treatment takes 7 hours. The problems found are the lack of security for operators inside the engine area due to the potential for accidents, inaccurate measurements because there is always a pause when communicating between operators inside and outside the engine area and inefficient maintenance time. The purpose of this study is to make a flow nozzle spray measurement system that is safe, accurate, and efficient. This research method uses literature and descriptive methods. The design of this system is done by creating a new display that contains a measurement menu and a record of flow spray measurement data through a Human Machine Interface (HMI) device in the form of an NS-8 Series Omron touch screen that is integrated with a Q-Series Programmable Logic Controller (PLC) type device. Mitsubishi as a controller. From the results of this study, it can be concluded that the flow nozzle spray measurement system display is safer and displays accurate and efficient measurement results because the measurement process is carried out automatically and is operated by one operator outside the machine area.</p> Joko Purwanto Karya Suhada Rukmanta Jayawiguna Aprilia Hananto Aviv Yuniar Rahman Copyright (c) 2020 SYSTEMATICS 2020-08-01 2020-08-01 2 2 58 64 10.35706/sys.v2i2.3771 Securing the Website Login System with the SHA256 Generating Method and Time-based One-time Password (TOTP) <p>Security to enter a system has a very important role because as the main entrance to access data sources. But often lack the attention of the owners and managers of information systems. To reduce these weaknesses, one method that is widely used today is to use One-Time password, which is where the password we have becomes dynamic, meaning that at a certain time the password is always changing, the positive side is that it makes it difficult for others to steal our passwords because besides representative passwords that are difficult to understand and passwords are always changing. This study discusses One-Time Password installed on a mobile device where the password is randomized using a combination of two algorithms, namely SHA256 and Time-based One Time Password. The development of this login method can reduce the level of theft of passwords owned by users who are entitled to access information sources.</p> Iman Permana Mardi Hardjianto Kiki Ahmad Baihaqi Copyright (c) 2020 SYSTEMATICS 2020-08-01 2020-08-01 2 2 65 71 10.35706/sys.v2i2.3756 Implementation of Motorcycle Rental Information System at the Trans Jaya Tangerang <p>The growth in science and technology is accelerating, resulting in a competition that is becoming more intense. Advanced science and technology are obviously also in contact with computers. Computer use can minimize potential errors in data processing compared with manual data processing. The development of these sciences and technologies also encourages companies to improve corporate performance, and one of their uses is the creation of the information systems that companies need. The purpose of this study is to design and build a desktop java-based motorbike rental information system for Koperasi Trans Jaya Tangerang. The methodology used by researchers was grounded research. The methods of data collection used in this study are interviews, observations, and library studies.</p> <p> </p> Aditya Setiawan Reza Avrizal Risma Nurul Auliya Copyright (c) 2020 SYSTEMATICS 2020-08-01 2020-08-01 2 2 72 78 10.35706/sys.v2i2.3847 Decision Support System to Determine the Location of a Cake Shop Retail Business Using the AHP Method and Simple Additive Weighting (SAW) <p>The number of research methods in the field of information technology provides choices for decision-makers to apply these methods to their business processes so that the application of these research methods can be developed into applications for researchers themselves or application program developers. In practice the process of implementing these research methods is developed and adapted to existing business processes so that in many implementations these methods can be combined with other methods, one of which is the method of collecting data combined with the method of sorting the decision process to provide an overview of the best results so can make decisions quickly and accurately. The method to be researched here is the AHP method as a data collection method and the Simple Additive Weighting (SAW) method, which is the method that provides the best sequence of results so that this research is expected to be helpful for a decision-maker in conducting future business actions. The research is a form of research from previous studies that discuss the same theme because in this study the researcher wants to get the results between the previous research and this research.</p> Didik Wiguna Copyright (c) 2020 SYSTEMATICS 2020-08-01 2020-08-01 2 2 79 85 10.35706/sys.v2i2.3831 Athlete Management Information System in KONI Karawang District <p>The Indonesian National Sports Committee or KONI is an organization that functions as a coordinating all athletes whose duty is to foster and develop the athletes become achievers in sports activities both at the regional and national levels. Koni Karawang is one of the authorized organization in coordinating every sporting activity in Karawang district and also functions as a forum for athletes in Karawang district so that it can accommodate all talented athletes so that they can be fostered further. Quite a lot of athletes in the Karawang district requires the management of data collection of athletes to be better coordinated. So, we need a system that can facilitate the management of KONI athletes in Karawang district. In this case, an Information System was created which functions to process the data of athletes in Karawang district, so that it would be assisting in the data collection of the athletes. The information system created is in the form of a website-based application with implementation using a PHP programming language and MySQL database</p> <p>&nbsp;</p> Bagja Nugraha Copyright (c) 2020 SYSTEMATICS 2020-08-01 2020-08-01 2 2 86 97 10.35706/sys.v2i2.3874
