Abstract

Electrical installation planning in a building is a vital aspect to ensure safety, efficiency, and operational comfort. This study aims to design an electrical installation system on the lobby floor of PT BIMOLI by referring to national standards such as PUIL 2011 and SNI. The methods used include a power requirement survey, calculation of active and apparent power, selection of distribution panel capacity, cable route planning, and determination of a protection system with MCB and grounding. The calculation results show a total power requirement of 63,675 Watts or 79,539 VA with a power factor of 0.8. After adding a 50% safety reserve, the required electrical capacity is 120 kVA. The installation design includes a single line diagram, wiring diagram, and calculation of cable requirements for lights, sockets, and air conditioners. The designed system meets aspects of energy efficiency, user safety, and applicable technical standards. The selection of 3x2.5mm² and 5x2.5mm² cables. Cable requirements for Downlights and TL Lamps ± 215 meters, cable requirements for 2pk AC ± 120 meters, cable requirements for 5pk AC ± 122 meters. Power distribution system, type of protection (MCB, grounding). Components such as downlights, TL lamps, NYM cables, as well as overcurrent and leakage current protection systems, have been adjusted to the characteristics and needs of office space. 3-phase MCB used for 5pk AC 16 Ampere, 1-phase MCB for 2pk AC 10 Ampere, 1-phase MCB used for TL Lamps and 4 Ampere Downlights, 1-phase MCB 32 Ampere Socket

Abstract

Electric switches are vital components in railway signaling systems, responsible for directing train tracks. At Jakartakota Station, single electric switches are prone to disturbances caused by high reverse voltage, which can blow 4 A fuses and halt operations. Based on this issue, this study analyzes the effect of using a 10 Ohm 100Watt resistor as a reverse voltage suppression solution. The title was chosen to reflect the specific component specifications, the type of switch system studied, and the precise research location, ensuring a clear research focus. The methodology included measuring current and voltage before and after resistor installation, analyzing system performance under both normal and obstructed conditions, and evaluating effectiveness without major modifications to indoor systems. The results show that installing the resistor reduced detection current from 4.1 A to 1.9 A, preventing fuse failures. Detection voltage remained within the relay’s operating range, while power voltage was unaffected. Compared to previous studies, the novelty of this research lies in its direct testing within an active operational environment, the use of resistor specifications tailored for high-current loads and outdoor conditions, and a practical approach that can be implemented without overhauling the entire system design. Thus, the use of a 10 Ohm 100Watt resistor is proven effective in enhancing the stability and reliability of electric switch systems, extending component lifespan, and supporting operational safety in Indonesia’s railway sector.

Abstract

The performance of induction motors in modern industries is crucial to prevent downtime due to unrecorded motor damage during preventive maintenance. The utilization of the Internet of Things (IoT) is highly beneficial due to the ubiquitous use of the internet, which can be leveraged to develop and implement a motor monitoring tool. This research employs various sensors, such as the PZEM004T-Open CT sensor for power detection, the SW-42 sensor for vibration detection, an infrared sensor for motor speed detection, and the DHT11 sensor for temperature detection, as well as an amp clamp meter, multitester, and thacometer. These tools are useful for detecting motor performance over time. This is a quantitative study. The results yield data in the form of numerical measurements that can be analyzed and compared with existing standards. The average calculated voltage value is 1.5 volts with an average deviation of 1.47%. The average current value is 0.01 amperes with an average deviation of 6.06%. The average power value is 0.52 watts with an average deviation of 1.67%. The average rotational speed is 221.5 RPM with an average deviation of 12.92%. The average vibration value is 1.53 mm/s, with a noticeable increase in vibration to be cautious of when the dimmer is set at 60%, which shows a vibration value of 0.36 mm/s. The average motor temperature is 37.9 ℃
