Ensuring optimal physical comfort, the need for a comprehensive evaluation of the performance of building systems was established. This investigation endeavors to meticulously scrutinize illuminance and light power density metrics across distinct temporal segments (morning, noon, afternoon, and night), as well as the dynamism of daylighting and artificial lighting presence within Tower C and D of Universitas Multimedia Nusantara (UMN). Noteworthy for their incorporation of double skin façades, these edifices serve as focal points of inquiry. The empirical findings reveal that illuminance levels within classrooms and offices, irrespective of natural or artificial lighting, consistently fall short of the prescribed 350 lux threshold based on SNI across most floor levels. The efficacy of the double skin façade manifests in a discernible attenuation, diminishing illuminance ingress to the building by approximately 50%, and precipitously by up to 90% about window fixtures. Furthermore, the analysis of light power density underscores an energy efficiency quotient hovering around 60%. These empirical insights are intended to serve as a foundational resource for guiding the initiation of Net Zero Healthy Greenship certification endeavors.

The ongoing COVID-19 pandemic has highlighted the critical importance of maintaining hand hygiene to prevent virus transmission. The virus can be present in carriers who may not display symptoms, making regular handwashing a crucial preventive measure. However, excessive water consumption during handwashing can strain water resources, particularly in regions facing water scarcity. This research presents an innovative system that combines effective handwashing with water conservation. The proposed system utilizes Arduino UNO, along with additional components such as resistors, ultrasonic sensors, an LCD, and LEDs, to guide individuals through a recommended approximately 20-second handwashing process. An ultrasonic sensor is employed to detect hand proximity, while an LCD provides instructions, and LEDs change color to signal the completion of the handwashing duration.

The widespread use of electricity today, which is primarily generated from fossil fuels, results in significant environmental consequences due to excessive consumption. Renewable energy has been proposed as a solution to mitigate this issue. In Indonesia, particularly in Pekanbaru City, the demand for electricity currently exceeds the supply. However, this region has substantial potential for renewable energy sources. This study presents the modeling and analysis of wind energy, specifically wind turbine systems, using MATLAB Simulink. The methodology involves identifying existing problems, collecting technical data relevant to Pekanbaru and turbine components, and designing the turbine system within MATLAB Simulink. The results of this system indicate a mechanical power output of 1,191 watts, along with a calculated torque of 48.63 Nm. These findings suggest that the system is suitable for small-scale electricity needs. Further research and considerations are necessary to optimize the design and application of turbine systems for sustainable energy production. By improving the efficiency and scalability of wind energy systems, Indonesia can better address its energy deficit while reducing the environmental impacts associated with fossil fuel consumption.

Engineering has played an important role in human activities through technological development and the Industrial Revolution. The significance of engineers conveys the need for professional graduates who comply with the world's demands. Thus, engineering education that fulfills certain standards is crucial. Aside from the technical aspect, non-technical abilities such as writing are similarly fundamental, especially for first-year students. Thus, this research is conducted to analyze the report writing of the first-year engineering students particularly for the engineering physics department of UMN in Basic Physics 2 Laboratory course. The qualitative method is used for a case study on four individuals, and their reports on 10 different modules are compared with the rubric assessment given by the lecturer. Results show sufficient understanding and performance of the topic and writing aspect though additional notes for further elaboration in data completion and critical analysis are needed to ensure improvisation as their self-efficacy and self-concept is considered low. Recommendations for students from the preparation to evaluation stages are given to build positive self-concept and self-efficacy.

Indonesia has a vast amount of potential for renewable energy, with many places still experiencing inaccessibility and inadequacy to electricity. One of the places, Kupang in East Nusa Tenggara, suffers a deficit of 4 MW at night along with a blackout despite the implementation of the Oelpuah Solar Power Plant that can produce 5 MW. Thus, this study presents a feasibility study and simulation of additional solar power plant implementation using PVSyst based on geospatial analysis by ArcGIS to point down the desired location, namely Oefafi. The results produce 7,212,139 kWh/year (almost 20 MWh/day using 6,552 modules of Jinkosolar 610 Wp JKM-610N-78HL4- BDV, 274 units of Growatt 12KTL3-X inverters, and 2000 BYD B-Box PRO 2.5 1,024 V 5,200 Ah battery. The losses of the systems mostly come from temperature loss in PV. The total installation cost is 51 billion IDR with a payback period of 8.3 years, NPV of 6.6 billion IDR, and IRR of 10.62% for an electricity tariff of 1,000 IDR/kWh. The amount of greenhouses saved accounts for 134,110.3 tCO2. This will help in filling the 4MW deficit while also potentially providing to other unsupplied regions. Future research may use other software for comparison and give better explanations.
