Rancang Bangun Sistem Informasi Pemantauan Pelaporan Di Unit Pusat Penelitian Dan Pengabdian Masyarakat Menggunakan Design Sprint
Full text linkPerkembangan sistem informasi telah menjadi bagian integral dalam mendukung efisiensi dan efektivitas operasional di berbagai sektor, termasuk dalam lingkungan pendidikan tinggi. Pusat Penelitian dan Pengabdian kepada Masyarakat (P3M) di Politeknik Negeri Jember (POLIJE) menjadi entitas penting yang membutuhkan solusi inovatif terkait pengelolaan administrasi pelaporan kegiatan penelitian dan pengabdian. Dalam konteks ini, penelitian ini bertujuan untuk merancang sistem pemantauan sebagai solusi terhadap keterlambatan pengumpulan laporan dan pengelolaan administrasi yang masih dilakukan secara manual. Metode Design Sprint diadopsi sebagai pendekatan utama dalam pengembangan sistem ini. Design Sprint memungkinkan identifikasi cepat masalah, pengembangan prototipe, dan pengujian langsung dengan pengguna potensial dalam waktu yang singkat. Langkah-langkah metodologi ini mencakup tahapan pemahaman masalah, brainstorming ide, pemilihan solusi terbaik, pembuatan prototipe, dan validasi melalui pengujian dengan pengguna. Hasil dari penelitian ini diharapkan dapat meningkatkan produktivitas dosen dalam pengumpulan laporan, menjadikan proses pengelolaan administrasi lebih disiplin, serta menciptakan keterpaduan, transparansi, dan pengawasan yang efisien antara dosen dan unit P3M. Dengan demikian, sistem informasi yang dihasilkan diharapkan dapat memberikan kontribusi signifikan dalam mendukung visi P3M POLIJE untuk menjadi lembaga penelitian dan pengabdian kepada masyarakat yang unggul secara internasional

Data traffic, which is only 0.12% downstream and 0.04% upstream, shows that this game is friendly to Internet data traffic to be played on game consoles using a postpaid cable network in Jakarta
Uji Sensivitas Metode TOPSIS dan Weighted Product Pada Sistem Pendukung Keputusan Seleksi Kandidat Ketua Himpunan Mahasiswa
Full text linkA student association is a student organization at a university that serves as a platform for student as-pirations and provides opportunities for self-development, skill enhancement, and leadership devel-opment through various student activities. Himpunan Mahasiswa Teknologi Informasi (HIMATEKNO) is the student association within the Information Technology Program at the Muhammadiyah Univer-sity of Purworejo (UMP). HIMATEKNO boasts a considerable number of members. Effective leader-ship is crucial for running this organization and ensuring its success. The process of selecting the HIMATEKNO chairman is essential to ensure that the chosen individual can lead the association suc-cessfully. The presence of a decision support system in the election of the HIMATEKNO chairman plays a significant role in the candidate selection process. A decision support system should incorpo-rate Multi-Attribute Decision Making (MADM) methodology. This research aims to conduct sensitivity testing on MADM methods, namely, TOPSIS and Weighted Product (WP). Based on the sensitivity testing results of the TOPSIS and WP methods, WP has a sensitivity test result of -0.000019%, while TOPSIS has a sensitivity test result of -0.00084%. As a result, WP is a more suitable method for im-plementing in the decision support system for the selection of the HIMATEKNO chairman due to its superior sensitivity level

Full text linkMuscle Spiker Shield is a tool used to record electrical signals generated by the muscles of the human body. These signals can provide important information about the health and activities of organisms, especially humans. As technology advances, more and more devices can be used to record the activity of these signals, including the Muscle Spiker Shield. One of the uses of the Muscle Spiker Shield is to monitor muscle wave activity. Human muscle waves are electrical signals generated by muscles and can provide information about the state of a person's movement activity. Monitoring human muscle wave activity can help in various fields, such as medicine, psychology, and sports. Currently, an electromyograph has been developed which functions as a voltage meter for all muscles to detect muscles in a state of tension and relaxation with the help of a microcontroller. On the Electromyography signal output then to the Arduino uno microcontroller. When using the Muscle Spiker Shield tool with MATLAB, the signals recorded by the tool are imported into the MATLAB software. Then, the data can be processed using various signal analysis techniques, such as filtering, peak detection and statistical processing. Some of the applications that can be done are monitoring leg and hand muscle wave activity during meditation, monitoring muscle wave activity to determine a person's movements, and monitoring muscle wave activity during exercise
