Abstract

The displacement of the stainless-steel plate to the printing work area is still managed manually by theoperator. Additionally, there is no clear benchmark to determine whether the plate is in the correct position andaligned according to the printed pattern. Thus, the print results are frequently less than perfect and require a longprocess. To address these conditions, an additional feeder is required with an automatic system that can operatein conjunction with the blanking machine, simplifying the operator's work and enhancing the blanking processefficiency. The objectives of this research are to determine the design of the feeder machine design by the needsand specifications of the machine, to discover the value of the safety factor of the Feeder machine design, and toreveal the movement system of the Feeder machine design using SolidWork 2019. This final project was carriedout in June 2023 at Politeknik Industri Logam Morowali (PILM) in Labota Village, Bahodopi District, MorowaliRegency, Central Sulawesi Province. The results show that: Researchers can make a design with the provisionsof a length of 550 mm and a width of 250 mm, while the known safety factor value for both areas is declared safesince it has Factor of Safety (FOS) value of 1 and the design movement system displayed on the animation systemin SolidWork 2019 software.

Abstract

Studi ini menata ulang sistem perencanaan kelistrikan gedung Pusat Data MMR 4 Deltamas Cikarang, dengan fokus pada keselamatan dan kenyamanan operasional sesuai SNI, PUIL, dan peraturan kelistrikan. Penelitian diawali dengan wawancara dengan konsultan perencana untuk mendapatkan dimensi bangunan (panjang, lebar, tinggi) serta kebutuhan daya server dan sistem pendingin, dilanjutkan dengan penyesuaian desain instalasi pencahayaan dan kelistrikan. Peralatan pencahayaan terdiri dari berbagai jenis lampu downlight (5 W, 6 W, 10 W, 12 W, 18 W, 20 W) dan lampu TL (2x18 W dan 1x18 W), serta 7 titik stopkontak. Sistem pendingin meliputi unit AC ½ HP, ¾ HP, dan 2 HP. Perangkat daya besar meliputi PAC 5,5 kW, UPS 30 kVA, ATS 150 A, dan COS bermotor. Kabel yang digunakan adalah NYY (1,5–10 mm²), NYA (1,5–2,5 mm²), dan NYGBY (50 mm²); proteksi disediakan oleh MCB (2–10 A) dan MCCB (16–125 A). Total kebutuhan daya mencapai sekitar 72,1 kW. Sumber daya utama adalah PLN 82,5 kVA (dua saluran), dengan dua generator cadangan masing-masing 100 kVA yang siap menggantikan jika terjadi pemadaman listrik. Kata kunci: Pusat Data, Sistem Tenaga, UPS, peralatan listrik.
