Abstract

An electric vehicle charging station (EV charging station) is an infrastructure designed to charge electricity for electric vehicles. However, most EV charging stations still rely on fossil energy sources. Innovation is needed to overcome this problem. One of them is through the use of solar panels. Using solar panels on the CBMS turns it into a clean and environmentally friendly energy source. However, environmental factors such as weather significantly affect the energy conversion produced by solar panels. Panels that are covered by trees and tall buildings cause partial shading conditions. Partial shading conditions can result in a direct decrease in PV output power. To overcome this, output power optimization using a DC-DC converter is required. The MPPT boost converter system with a modified P&O method is designed to maximize the output power of solar panels when partial shading occurs. The test results show that the developed system can maximize the output power of solar panels in partial shading conditions with an average power increase of 8.13 and an efficiency of 91%. This method can reduce the negative impact of changes in light intensity, keep the system close to the maximum power point, and improve the efficiency of charging electric vehicles at SPKL during unstable weather conditions. However, the modified P&O method is less effective in maximizing the output power in standard solar panels. This research does not address the effectiveness of solar panels concerning temperature, humidity, and dust.

Abstract

Abstract: Natural lighting has been widely studied by measurement and simulation methods. Aperture is the factor under study associated with the intensity of light in the room. Reflective materials in their kind are walls and furniture. It also plays a role in determining the intensity of light in a room. This study aims to examine the various materials commonly used for walls and their effect on the intensity of light in a room. The research method used in this study is a quantitative method with a simulation using dialux Evo 8.6 software. Research begins by creating a model. The room model is made of 7 pieces in a row. After the model is finished, a window with a size of 1 x 1.3 m is created. Each room will be given a different wall material. The result is a room with wooden walls has the highest light intensity. The lowest intensity is in a room with walls of glass block material. The order from lowest to highest after red brick is rough plaster, followed by concrete, vinyl and then ceramic. This has to do with the condition of the surface of the material. The conclusion is that a room that has walls with a rough surface will experience a decrease in light intensity due to light diffraction. Color plays a role as an absorber of light. Even though the surface is smooth, if the color of the field is dark, the room will have low light intensity.Keyword: natural lighting, walls, inner reflection, light intensityAbstrak: Pencahayaan alami sudah banyak diteliti dengan metode pengukuran dan simulasi.

Abstract

Research on logical reasoning began to be carried out in Indonesia, it is necessary to conduct an evaluation of the psychometric characteristics possessed by logical reasoning measurement tools made by researchers. Logical reasoning measurement tools made by researchers need to be re-evaluated considering there are weaknesses in terms of using a relatively small number of subjects, so that it can affect the standardization of logical reasoning measuring devices. This study aims to obtain an overview of item difficulty index, item discrimination index, effectiveness of the distractors, validity, reliability, and error measurement from the logical reasoning measurement tool. Respondents in this study amounted to 7.730 students, consisting of 3.897 men and 3.833 women with an age range of 15-19 years. The research data were analyzed with the help of Microsoft Excel 2007, SPSS version 22.00, and ITEMAN version 3.6. The results of this study indicate that the item difficulty index moves from 0.35 to 0.80 which belongs to the easy and medium category. This study also shows that the item discrimination index moves from 0.10 to 0.71 with four items rejected and need to be aborted. This study also shows that the effectiveness of the distractors contained in each item in the logical reasoning measure is in the effective category. This study also shows that each item in the logical reasoning measure is considered valid in terms of factorial validity through exploratory factor analysis (EFA) procedures. This study also shows that the measurement of logical reasoning is relatively reliable with a Cronbach Alpha coefficient of 0.906. This study also shows that the measurement error obtained in this study is ± 3.92 of the total score obtained using a logical reasoning measure with a confidence level of 95%, with the actual score estimate obtained by respondents moving from 12.08 to 19.92, if the scores obtained by respondents sixteen.

Abstract

As energy sources continue to dwindle, they have garnered significant attention, prompting the government to set a target of at least 31% of Indonesia's total energy consumption coming from renewable sources. This study focuses on developing an inverter, a device that converts direct current (DC) into alternating current (AC), utilizing a 12V/100Ah battery to support a 150-watt AC load. The proposed inverter adopts a full-bridge configuration with single-phase sinusoidal pulse width modulation (SPWM) and incorporates a fuzzy logic controller to ensure stable output voltage. The implementation results indicate that the designed full-bridge inverter produces a steady output aligned with the input from a 12V LiFePO4 battery, as confirmed by data collection which compared the output with and without control, showing that the controlled system yields a more stable output. The testing results of the full-bridge inverter using the SPWM method indicate that the system can produce an AC output voltage of 221–224 V with a frequency of 50 Hz, in accordance with the established standards. In contrast, during testing without control, the output voltage ranged only between 145–147 V with a frequency of 99.18 Hz, which does not meet operational standards. These results clearly demonstrate the effectiveness of the fuzzy controller in maintaining both voltage and frequency stability under varying operating conditions. By accurately adjusting the system response, the fuzzy controller ensures that the inverter consistently delivers output within the desired standard range, thereby enhancing the overall performance and reliability of the system.

Abstract

Penelitian ini merupakan penelitian hukum dengan spesifikasi yang bersifat deskriptif analitis. Upaya Direktorat Lalulintas Polda Sumbar dalam penertiban pengendara sepeda listrik di jalan raya dengan pendekatan preventif melalui edukasi dan sosialisasi aturan berlalu lintas kepada masyarakat pengguna sepeda listrik agar mereka memahami risiko dan tanggung jawab dalam berkendara. Pendekatan represif dapat dilakukan dengan menegakkan hukum secara tegas terhadap pelanggaran yang dilakukan oleh pengguna sepeda listrik, seperti tidak mematuhi aturan lalu lintas atau mengendarai sepeda listrik secara sembarangan di jalan raya. Kerja sama dengan berbagai pihak terkait dalam merumuskan regulasi yang lebih jelas. Kampanye keselamatan berlalu lintas dilakukan melalui berbagai media, baik secara langsung dalam bentuk penyuluhan kepada pengguna jalan maupun melalui media sosial dan platform digital. Kendala yang ditemui dalam penertiban pengendara sepeda listrik di jalan raya oleh Direktorat Lalulintas Polda Sumbar sebagai upaya mencegah terjadinya kecelakaan lalu lintas adalah kurangnya regulasi yang jelas mengenai status hukum kendaraan ini dan aturan penggunaannya. Tidak ada kepastian hukum tentang apakah sepeda listrik dikategorikan sebagai kendaraan bermotor atau non-motor juga menyebabkan kebingungan dalam penerapan aturan terkait kelengkapan kendaraan. Kurangnya rambu-rambu lalu lintas yang mengatur penggunaan sepeda listrik. Di banyak titik rawan kecelakaan, masih belum tersedia rambu peringatan atau petunjuk yang memberikan informasi kepada pengguna sepeda listrik mengenai jalur yang aman untuk mereka lalui. Terbatasnya sumber daya dan personel penegak hukum juga menjadi kendala dalam penertiban pengguna sepeda listrik. Saat ini, jumlah petugas lalu lintas yang bertugas di lapangan masih belum mencukupi untuk secara efektif mengawasi dan menindak pelanggaran yang dilakukan oleh pengguna sepeda listrik.

Abstract

Lighting is very important in the classroom. The layout or orientation, window openings and area of the building must be considered so that sunlight entering the classroom can meet the standart. The purpose of this study was to find out how much light intensity is in the classroom and whether it is in accordance with SNI standards, so that it is comfortable for learning. This research method uses qualitative methods by observing interviews and quantitative methods by using simulations. The results showed that first grade class has an average of 1000 lux for 08.00 AM however, towards 12.00 PM the intensity of incoming light decreases to an average of 100 lux. Second grade has an average of 500 lux for 08.00 AM but towards 12.00 PM the intensity of incoming light decreases until it has an average of 100 lux. Grade three has an average of 300 lux at 14.00 PM and towards 16.00 PM the light intensity only decreases slightly so that it has the same average. The results of the interviews showed a lack of lighting during learning activities. The conclusion is that the average intensity value in the class measured is sufficient, but the distribution is uneven, so artificial lighting is needed.
