Abstract

Penelitian ini mengeksplorasi proses dan efektivitas audit sistem informasi (SI) di Perusahaan Teknologi XYZ. Penelitian ini bertujuan untuk mengevaluasi praktik audit SI saat ini, mengidentifikasi potensi risiko, dan merekomendasikan perbaikan. Metode kualitatif digunakan, termasuk wawancara dan analisis dokumen. Temuan menunjukkan bahwa meskipun XYZ memiliki mekanisme audit SI yang kuat, terdapat beberapa area yang memerlukan peningkatan dalam manajemen risiko dan kepatuhan. Implikasi penelitian ini menyarankan kerangka kerja untuk praktik audit yang lebih baik di perusahaan teknologi serupa.

Abstract

PT Swadaya Graha is a company that works in the field of construction, fabrication and steel manufacturing. One of the machines used in carrying out its operational activities is the Baoji 1660A lathe. The lathe often fails during the production process. This study aims to determine critical components, critical component reliability values, maintenance scheduling intervals and maintenance cost estimates of the Baoji 1660A lathe using the Reliability Centered Maintenance (RCM) method. The results of this study show that the electrical system with an RPN value of 240, v-belt with an RPN value of 168, and gearbox with an RPN value of 60 as critical components. The reliability value of the electrical system approaches 0.5 at a time interval of 640 hours or 80 working days, the reliability value of the v-belt approaches 0.5 at a time interval of 208 hours or 26 working days, and the reliability value of the gearbox approaches 0.5 at a time interval of 384 hours or 48 working days. From the scheduling interval, the estimated total maintenance cost in 2025 is IDR 7,019,092, in 2026 is IDR 3,615,386, in 2027 is IDR 4,187,484, in 2028 is IDR 4,276,752, and in 2029 is IDR 3,615,386.

Abstract

The rapid development of technology demands solutions to optimise heat management for electronic components. Through this study, the researchers evaluated the effectiveness of various types of coolants in a liquid cooling system for electrical equipment, especially CPUs. Using design simulations conducted through SolidWorks software, this research aims to optimise the flow rate and selection of coolant type to achieve maximum thermal efficiency and reduce production and operational costs. The simulation results show that water is the most efficient coolant with significant temperature reduction compared to Ethylene Glycol (EG), Propylene Glycol (PG), and silicone oil. Water shows a temperature drop of 11.76°C, while EG and PG show a temperature drop of 8.82°C and 7.35°C respectively and silicone oil shows a temperature drop of 4.9°C. It can be seen from the simulation that water shows the most effective temperature reduction compared to EG, PG, and Silicone Oil.

Abstract

Research on weather elements is very necessary for the benefit and welfare of mankind, the observed weather elements will become material for predicting the weather in the future. This data is also used to prevent the risk of adverse impacts caused by the weather itself. To measure the weather with this automatic system, a tool called AWS is needed. The AWS design requires a Rasberry Pi. By using this Rasberry Pi we can monitor weather changes originating from BMKG via the web in the form of an Analog Gauge.
