The presence of congregants in the church plays a crucial role in monitoring the church's development and maintaining accurate attendance records. However, in GKPY VTI church, the current method of collecting attendance data is inefficient, often resulting in lost or damaged data. The absence of a weekly attendance system further compounds the issue. An efficient solution is needed, including the provision of data reports to assist the church's observation team. In an effort to address these challenges, we have designed and implemented an Android-based application utilizing face recognition technology with the Tensorflow method. This research involves planning, analysis, design, and implementation phases.The research results demonstrate that this application successfully records congregants' attendance by recognizing their faces. This success facilitates the church's observation team in obtaining attendance information during each weekly worship service more efficiently. For future development, further research can focus on integrating eye detection features into the attendance system and expanding the application's functionality by adding features such as communal prayer, baptism registration, and services for congregants.

Ramona dyah safitri, Junaidi Akbar, Subur Pramono — Mon, 29 Apr 2024 00:00:00 +0000

Air bersih merupakan kebutuhan mendasar bagi kehidupan manusia. Namun ketersediaan air bersih semakin terbatas, terutama di daerah pesisir dan pulau-pulau kecil yang dikelilingi air laut. Alat desalinasi konvensional atap satu sisi merupakan teknologi sederhana yang memanfaatkan energi matahari untuk menguapkan air laut dan mengumpulkan kondensatnya sebagai air tawar. Penelitian mengenai pengaruh filter warna pada alat desalinasi konvensional atap satu sisi masih terbatas. Penggunaan filter warna pada alat desalinasi surya telah menunjukan potensi untuk meningkatkan penyerapan panas dan produktivitas air tawar. Penelitian ini bertujuan untuk menganalisis pengaruh filter warna ungu dan merah terhadap produktivitas alat desalinasi konvensional atap satu sisi. Pengambilan data dilakukan pada jam 08.00-16.00 WIB diulangi setiap 30 menit. Filter warna yang digunakan adalah filter warna ungu memiliki panjang gelombang 380–420 nm dan filter warna merah 620-750 nm dengan kemiringan sudut yang digunakan 10^o. Penelitian ini didapat bahwa rata-rata laju perubahan temperatur per satuan waktu pada sistem dengan filter warna ungu lebih besar 0.04^oC/min dibandingkan dengan sistem filter warna merah 0.03^oC/min. Hal ini sesuai dengan teori yang menyatakan bahwa foton dengan panjang gelombang ungu memiliki energi yang lebih besar dibandingkan dengan foton yang memiliki panjang gelombang warna merah yang mengakibatkan energi kalor yang diserap oleh sistem lebih besar. Peningkatan kalor yang diserap oleh filter warna ungu menghasilkan volume air yang lebih banyak sebesar 12.4 ml, sedangkan filter warna merah menghasilkan volume air yang sebesar 10.7 ml.

Amin Suyitno, Dwi Mahardiyan, desiana Br Ginting — Mon, 29 Apr 2024 00:00:00 +0000

This paper presents the analysis and design of speed control for a Torque Motor Drive System. The system presents a torque drive and motor which generally consists of a induction motor and a load connected by a flexible shaft which can be called a Two-Mass Resonance System. To design motor speed controller in this system, a comprehensive and detailed system analysis is required. To realize the design of this control system, it is impossible if the feedback point is taken at the load location, due to the influence of vibration from the flexible shaft. The motor speed control design method used in this paper is to use the Zeroing control design by simulating to see the system output results. From the simulation results, the system output response looks good.
