Abstract

Energy efficiency in office buildings has become a critical issue due to increasing electricity consumption, particularly in lighting systems that operate continuously. Inefficient lighting design can lead to excessive energy use, higher operational costs, and reduced sustainability performance in commercial buildings. Objective: This study aims to analyze the implementation of Light Emitting Diode (LED) technology to improve energy efficiency in office lighting systems using DIALux simulation, while ensuring compliance with standard illumination requirements. Method: This research employs a quantitative descriptive approach supported by simulation modeling. Data were collected through field observation, illumination measurement using a lux meter, and documentation of room specifications. The analysis was conducted using DIALux software to evaluate illuminance levels, light distribution, and energy consumption based on office lighting standards. Findings: The results indicate that the LED lighting system achieves an average illuminance of 340 lux, which meets the SNI 6197:2011 standard (300–500 lux), with a uniformity ratio of 0.68 indicating adequate light distribution and visual comfort. The system consumes 36 kWh per month, which is more than 50% lower than conventional fluorescent (TL) lighting systems. Implications: The findings suggest that LED lighting systems can provide efficient and compliant lighting solutions while significantly reducing energy consumption and operational costs. This supports the implementation of energy-efficient and sustainable building practices. Originality: The originality of this study lies in its integrated approach that combines room characteristics, LED configuration, and DIALux simulation to evaluate lighting performance and energy efficiency simultaneously, offering a practical framework for office lighting design.

Abstract

Electrical installation systems in healthcare facilities must ensure safety, reliability, and operational continuity because medical services depend on stable power supply and adequate lighting conditions. In polyclinic environments, electrical disturbances may affect service quality and patient safety, making proper system design essential. Objective: This study aims to design and evaluate the electrical installation of the Cibubur Hospital Polyclinic based on national standards, focusing on load distribution, lighting performance, backup power systems, and grounding effectiveness. Method: This research employs a mixed qualitative–quantitative descriptive approach. Data were collected through field observations, direct measurements using electrical instruments (clamp meter, lux meter, and earth tester), and documentation review of installation layouts and technical standards. The analysis was conducted through technical calculations and standard-based evaluation. Results: The total electrical load is divided into 11,883 W for normal PLN load and 7,406 W for priority UPS load, indicating a functional separation between general and critical services. Lighting measurements show that seven out of ten rooms meet the required standards, while three rooms remain below the threshold. The grounding system demonstrates resistance values well below the allowable limit, indicating effective protection performance. Implications: The results indicate that integrated electrical installation design can support safe and continuous healthcare operations, although improvements in lighting uniformity and system specification consistency are still required. Originality: This study offers an integrated evaluation of load distribution, lighting, backup power, and grounding within a single polyclinic case study, providing practical and academic contributions to electrical system design in healthcare facilities.

Abstract

This paper presents a systematic literature review on the feasibility and practicality of implementing Modified Gate Diffusion Input (MGDI) logic for a static random access memory(SRAM) design at the 45-nm technology node. The study consolidates prior simulation-based and analytical findings to evaluate MGDI as a low-power alternative to conventional CMOS in memory circuits. Results highlight that MGDI enables significant reductions in dynamic power consumption, particularly in peripheral circuits such as decoders and drivers, where switching activity dominates. Average leakage power was also reduced by approximately 20%, with up to a 40% reduction observed in stacked configurations, owing to the intrinsic characteristics of MGDI structures. Stability analysis indicated that hold Static Noise Margin (SNM) remained comparable to CMOS cells, while read SNM improved by 5–10% due to the stacking effect and the use of swing-restoration transistors. A moderate delay penalty of about 10% was identified at the bit-cell level, but the difference was offsetby faster operation in MGDI-based peripheral circuits, resulting in improved energy-delay efficiency overall. Importantly, MGDI can be fabricated using standard CMOS processes without requiring exotic modifications, demonstrating practical compatibility. These findings suggest that MGDI is a promising candidate for ultra-low-power memory applications, particularly in Internet of Things (IoT) and energy-harvesting devices.

Abstract

The heightened utilization of nonlinear electrical loads in skyscrapers can produce harmonic distortion that impacts power quality. This research is to examine the attributes of Total Harmonic Distortion of current (THD-I) and Total Harmonic Distortion of voltage (THD-V) inside a low-voltage distribution network comprising multiple panels. Measurements were executed utilizing the Schneider PowerLogic PM5300 across eight distribution panels, specifically Tower E, Tower F, Tower G, Tower H, Tower J, Tower K, FIRE, and Utility/Non-Fire. Observations took place over a span of four days at 06:00, 08:00, 14:00, 18:00, 22:00, and 23:00 throughout three phases, yielding 576 initial data points for both THD-I and THD-V. The evaluation procedure uncovered four sets of THD-I and THD-V data for phase 1 on August 9, 2026, at 08:00, which necessitated verification and were consequently excluded from the primary assessment. The peak THD-I values among the panels vary from 12.1% to 40.2%, with the FIRE panel exhibiting the highest measurement. The confirmed maximum THD-V values among the panels vary from 2.0% to 2.9%, with the peak value identified in the Utility/Non-Fire panel. All confirmed THD-V values are beneath the benchmark of 8% for systems operating at voltages up to 1 kV, according to IEEE Std 519-2022. Nevertheless, these findings do not suffice to assert complete adherence to IEEE 519, as the measurement location has not been validated as the Point of Common Coupling. THD-I is examined descriptively and is not utilized to assess current harmonic compliance due to the unavailability of short-circuit current (Isc) and maximum demand load current (IL) data necessary for Total Demand Distortion analysis. The capacitor bank's supporting data indicates a power factor ranging from 0.96 to 1.00. The findings indicate that a power factor nearing unity does not consistently correlate with little current harmonic distortion. Consequently, THD-I, THD-V, and power factor must be analyzed as supplementary metrics in evaluating the power quality of a building's electrical infrastructure.

Abstract

This community service program aimed to improve electrical safety literacy among older adults through education on lightning risk and household grounding systems. The program used a participatory educational method consisting of partner needs identification, preparation of learning materials and instruments, pre-test, visual education, grounding system explanation, interactive discussion, post-test, and follow-up reflection. The materials covered misconceptions about smartphones and lightning, the function of grounding, household electrical safety, circuit breakers, and safe actions during thunderstorms. Evaluation was conducted using five indicators. The results showed improvements across all indicators: understanding of lightning misconceptions increased from 40% to 90%, grounding function from 35% to 88%, electrical safety from 50% to 92%, actions during lightning from 45% to 85%, and household installation understanding from 30% to 80%. The average increase reached 47%. These results indicate that simple, visual, and contextual education can improve older adults' understanding of grounding and lightning safety. The program supports community-based electrical safety literacy and encourages families to check household electrical installations with qualified technicians.
