Abstract:
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.

Abstract:
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.

Abstract:
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.

Abstract:
Kriptografi merupakan suatu metode yang dapat digunakan untuk mengamankan data. Data yang biasanya diamankan menggunakan kriptografi adalah data teks. Data teks biasa digunakan dalam pesan untuk berkomnikasi. Isi pesan tersebutlah yang diamankan dengan kriptografi. Prosedur utama dalam kriptografi ada dua, yaitu enkripsi dan dekripsi. Enkripsi merupakan prosedur yang dilakukan untuk menyandikan suatu data atau pesan asli menjadi data atau pesan bersandi. Sebaliknya, dekripsi merupakan prosedur yang dilakukan untuk mengembalikan pesan atau data yang disandikan menjadi pesan atau data asli seperti semula. Kriptografi memiliki beragam algoritme, salah satunya yaitu algoritme Advanced Encryption Standard (AES). AES merupakan salah satu algoritme kriptografi yang memiliki tingkat keamanan yang tinggi. Pada penelitian ini dilakukan implementasi algoritma AES untuk mengamankan data berupa video dengan format mp4. Pengujian dilakukan dengan menggunakan aplikasi kriptografi yaitu CrypTool. Untuk dapat dienkripsi dan didekripsi, data video diubah dalam bentuk HexDump. Dari penelitian ini dihasilkan bahwa algoritme AES efektif untuk mengamankan data video. Data video yang terenkripsi tidak dapat diputar dengan media player dan tidak memilik detail informasi seperti data aslinya. Akan tetapi ketika didekripsi data tersebut berhasil diputar secara normal dengan media player dan memiliki detail informasi seperti data aslinya.
