Abstract

The prevalent manual method of replacing ceiling lamps, which often involves climbing on unstable furniture, poses significant safety risks, including potential falls, electrocution, and other severe injuries. This common practice underscores an urgent need for safer and more efficient lamp maintenance solutions in both domestic and commercial settings. This research aims to mitigate these inherent dangers by developing and upgrading conventional ceiling lamp changers into a semi-automatic system. The primary objectives are to enhance the safety, speed, and overall ease of the lamp replacement process, thereby effectively minimizing the risk of user injury. The proposed methodology involves designing a semi-automatic ceiling lamp changer by integrating a control switch mechanism that enables remote rotation of the lamp holder. This innovative approach will facilitate the safe removal and installation of lamps without direct manual contact or the necessity of climbing. Concurrently, comprehensive product cost planning and market-driven pricing strategies will be conducted to ensure the device’s affordability and widespread community acceptance. The successful development of this semi-automatic ceiling lamp changer is anticipated to provide a significantly safer, faster, and more convenient alternative for lamp replacement. This remote-operated design is expected to substantially reduce injury incidents associated with current manual methods. By ensuring affordability and market compatibility, this innovation aims to achieve broad community adoption, ultimately contributing to safer environments for lamp maintenance.

Abstract

Masjid adalah tempat ibadah bagi umat Muslim, yang digunakan untuk melaksanakan berbagai aktivitas keagamaan, terutama salat (sholat) berjamaah. Selain sebagai tempat beribadah, masjid juga sering berfungsi sebagai pusat kegiatan sosial, pendidikan, dan dakwah dalam komunitas Muslim. Di dalam masjid, umat Muslim melaksanakan ibadah wajib seperti salat lima waktu, salat Jumat, serta kegiatan keagamaan lainnya seperti pengajian, ceramah, dan acara sosial. Secara umum, masjid bukan hanya tempat ibadah, tetapi juga pusat kebersamaan, penguatan iman, serta penyebaran ilmu dan ajaran agama Islam dalam masyarakat. Wilayah RT 44 RW 10, Kelurahan Kepuharjo, Kecamatan Karangploso, Kabupaten Malang sedang melakukan pembangunan masjid. Dalam proses finalisasi pembangunan dibutuhkan sistem instalasi audio yang baik dan berkualitas. Metode yang dilakukan untuk mengatasi masalah tersebut yaitu melakukan observasi dan analisis spesifikasi pada peralatan sound sistem yang sudah terpasang. Hasil dari analisis sistem audio tersebut adalah dengan menerapkan sistem audio untuk sound dalam ruangan. Pemasangan audio memungkinkan pengurus masjid untuk menyampaikan pengumuman dan informasi dengan jelas kepada jamaah, serta memfasilitasi komunikasi yang lebih baik selama berbagai kegiatan di masjid. Sehingga dengan sistem tata suara dan instalasi audio di masjid bukan hanya meningkatkan kenyamanan ibadah, tetapi juga memastikan komunikasi yang lancar dan pengalaman spiritual yang lebih baik bagi seluruh jamaah.

Abstract

Thin films, characterized by small-dimensional materials on a substrate formed through sequential deposition of ionic/molecular/atomic materials, have gained significance in various industries. An emerging method, Arc Plasma Deposition (APD), is gaining attention for its effectiveness in minimizing environmental pollution. This research explores the potential of APD, an environmentally friendly technique, in coating materials, particularly copper, at a laboratory scale. The objective is to introduce a cost-effective solution for material deposition, addressing the industrial need for efficient and eco-friendly coating processes. A laboratory-scale prototype for coating materials, specifically utilizing copper metal, is introduced and tested. The APD process is conducted in an atmospheric free-oxygen chamber, where plasma is generated. The deposited copper is analyzed concerning the deposition time, providing insights into the efficiency of the APD technique. The laboratory-scale prototype demonstrates the feasibility of using APD for coating materials. The results indicate the potential of APD in efficiently producing thin films, making it a promising alternative for industrial applications.
