This study uses the Research and Development method, the learning media that will be developed refers to the ADDIE (Analyze, Design, Development, Implement, Evaluation) model. This analogy-based device is very suitable to be used for the lecture process after going through a validation process by media experts and getting an average percentage of 82%.

This study compares the best compression method between WMV and AVI with MP4 video material. the comparison process is done by calculating the compression ratio (cr), space-saving (ss), and peak signal to noise ratio (PNR). The results obtained prove that AVI video compression has the highest compression ratio value of 0.063, while in terms of space-saving (ss) WMV compression gives the best performance with a value of 99.826. The best measurement in terms of PSNR is AVI video compression because it has the highest average value among all compressions, which is 36,158. provides the best performance in maintaining compression quality. Overall the MP4, AVI, and WMV compression methods used for videos can reduce the file size and preserve the information and quality of the video</p> 2022-06-19T00:00:00+00:00 Copyright (c) 2022 JURISTIK (Jurnal Riset Teknologi Informasi dan Komputer) https://jurnal.umnu.ac.id/index.php/juristik/article/view/474 Rancang Bangun Sistem Informasi Pendataan Beasiswa PTMA Berbasis Web Menggunakan Metode Waterfall 2022-08-26T14:11:07+00:00 Muhamad Rosidin rosidin@sibermu.ac.id Wicaksono Yuli Sulistyo wicaksono@sibermu.ac.id Khairina Eka Setyaputri khairinaekasetyaputri@sibermu.ac.id Joko Supriyanto joko@sibermu.ac.id <p><em>The development of information technology, especially the internet, is the main factor driving the development of web-based information systems. The ease of accessing information via the internet greatly supports the development of online data collection for Muhammadiyah Aisyiyah Higher Education (PTMA) scholarships. Data collection of PTMA scholarships is very useful for Diktilitbang Muhammadiyah in recording scholarships at each PTMA because previously there was no data collection using a web-based system. The purpose of the research is to design a web-based scholarship data collection application to facilitate PTMA data collection and reporting. The research method used in designing the application uses the waterfall method. This method is often referred to as the "classic lifecycle" so that it can provide an alternative solution to the scholarship data collection system to make it easier for users to report scholarship data at each PTMA. The results achieved from the design are an application with a code igniter framework in web form that has several features such as scholarship management and member management which are expected to assist web managers in collecting and reporting scholarship data.</em></p> 2022-06-16T00:00:00+00:00 Copyright (c) 2022 JURISTIK (Jurnal Riset Teknologi Informasi dan Komputer) https://jurnal.umnu.ac.id/index.php/juristik/article/view/502 Website-Based Multimedia Lab Practicum Equipment Borrowing System 2022-09-09T03:44:22+00:00 Hanif Adi hermawan hermawan mask16hanif@gmail.com Akhmad Fadjeri akhmadfadjeri@umnu.ac.id <p><em>SMK Ma'arif 1 Kebumen has learning facilities that are very interesting for students to learn, namely laboratories/studios.

The compression not only affects the file size but also affects the quality of the image. Measurement of image quality subjectively (human senses) can be done to assess image quality, but it is very difficult to do because the condition of the assessment must depend on human vision, therefore objective assessment is very necessary because it produces standard, fast, and easy measurements. This study was conducted to find the best compression among the three social media, using the assessment of the compression ratio and Peak Signal Noise Ratio (PSNR). The calculation of the compression ratio obtained shows that the compression ratio on WhatsApp has the highest average of 93.93% while the lowest average compression ratio is on Twitter, which is 62.96%. Another objective assessment uses PSNR calculations which can be concluded that the compression on Twitter has the highest PSNR value with an average of 30 dB, while the lowest PSNR value is on WhatsApp, which is 19 dB.</span></em></p> 2022-06-16T00:00:00+00:00 Copyright (c) 2022 JURISTIK (Jurnal Riset Teknologi Informasi dan Komputer)
