A dye sensitized solar cell (DSSC) is a low-cost solar cell with attractive features. DSCC contains of photoelectrode, dye, electrolyte, and counter electrode with photoelectrochemical system. The aim of this research is to determine the percent efficiency produced by DSSC from the Mahkota Dewa extract. This was carried out in various stages, namely sample preparation and extraction, DSSC assembly, TiO2 characterization using Scanning Electron Microscopy (SEM), and testing its current and voltage. The results showed that the maximum wavelength of the Mahkota Dewa extract dye test using a UV-Vis spectrophotometer was 554 nm with an absorbance of 0.163, which was believed to be the wavelength of flavonoid and anthocyanin compounds. Based on the characterization results, surface morphology was spherical and agglomerated. However, after being soaked in the dye, the surface morphology of the TiO2 layer did not appear spherical on the surface that was expected to have been covered by the dye. The measurement using sunlight sources showed that the maximum current and voltage of DSSC with a concentration of 30% w/v was 21.8x10-4A and 58.86 V with an efficiency of 22.43x10-3 %. In addition, there was a 0.482% decrease in DSSC efficiency based on the storage time which lasted for a period of 6 days.

AbstractThe quality of electrical energy is a crucial requirement for the Akademi Komunitas Negeri (AKN) Aceh Barat. Electrical outages negatively impact performance, as equipment cannot be utilized during these times. A generator set is a machine that produces electrical energy and serves as a backup when the electrical supply from PLN is interrupted. Currently, AKN Aceh Barat has a generator set with a capacity of 7,800 watts, which is insufficient to meet the academy's power demands. The average monthly energy consumption from April to September 2024 is 5,199.83 kWh. To overcome the lack of power from the generator set, priority loads have been designated based on the importance of different rooms that facilitate essential services, ensuring that teaching and learning activities can proceed effectively. The generator's backup energy primarily supports a load of 6,290 watts, reaching an operational loading percentage of 81%. The electrical energy distribution from the generator to these priority rooms is managed through a new installation known as the Automatic Transfer Switch (ATS) panel, which activates automatically when the electrical supply from PLN is disrupted.Keywords:Power; Electrical; Distribution; Generator; EfficiencyAbstrakKualitas energi listrik menjadi kebutuhan utama bagi Akademi Komunitas Negeri Aceh Barat, pemadaman energi listrik berdampak buruk terhadap kinerja yang disebabkan peralatan tidak dapat digunakan.

Traffic Steering is an additional technique applied to network traffic especially when filtering, modification, or optimization is required. Network operators usually use traffic steering to expand the value of VAS or value-added service (value-added service that refers to additional services (content) based on existing telecommunication networks). This technique is applied so that the use of traffic from a link can be directed according to the client's needs and further maximize the functional use of the link itself. In general, the implementation of traffic steering is built based on three concepts, namely: NAT (Network Address Translation), Firewall RAW, and IP Routes. In this Traffic Steering implementation, the DSTNAT chain feature on the NAT firewall is used to direct access with the destination that has been set to a specific web server.

Budget efficiency represents a critical determinant of organizational performance in resource-constrained higher education environments, yet empirical evidence examining its specific impact on non-academic support staff remains limited, particularly in regional Indonesian universities. This study investigates the relationship between budget efficiency and educational support staff performance in public universities of West Aceh Regency, guided by Performance-Based Budgeting theory and Goal-Setting Theory. Employing a sequential explanatory mixed-methods design, the study collected quantitative data from 80 educational support staff through validated questionnaires (Cronbach's α = 0.89-0.91) and qualitative insights from 10 key informants via semi-structured interviews. Pearson correlation and hierarchical multiple regression analyses examined relationships between budget efficiency dimensions (allocation accuracy, utilization effectiveness, transparency) and performance outcomes (task efficiency, service quality, professional development). Budget efficiency demonstrated strong positive correlation with staff performance (r = 0.674, p < 0.001) and accounted for 45.4% of performance variance (R² = 0.454, F (1,78) = 64.73, p < 0.001). Allocation accuracy emerged as the dominant influence factor (score: 88/100), followed by transparency/accountability (85/100) and staff participation (82/100). Qualitative findings revealed dual pathways: material mechanisms (resource adequacy enabling task execution) and psychological mechanisms (perceived organizational support enhancing motivation). Budget efficiency influences educational support staff performance through interconnected material and motivational pathways rather than resource availability alone. Universities should prioritize participatory budgeting, transparent financial reporting, and allocation-need alignment. Policymakers must recognize that performance-based funding requires parallel institutional capacity development to ensure equitable efficiency gains across administrative units.

AbstractThis paper presents a systematic literature review on determining the optimal tilt angle (OTA) for photovoltaic solar panel installation. The research method uses a systematic literature review approach by analyzing 30 scientific articles published between 2013 and 2025 from the IEEE Xplore, ScienceDirect, MDPI, and Springer databases. The analysis results show that geographic latitude is the dominant factor in determining OTA, with tropical regions requiring an angle of 5°-15° and mid-high latitude regions requiring 30°-60°. The research methodology has evolved from a simple empirical approach to the use of machine learning and artificial intelligence with a prediction accuracy of R² 0.95. For equatorial regions such as Indonesia, the optimal angle ranges from local latitude ± 5° with low sensitivity to deviation (±5° only affects output 3%). The study also identified that seasonal adjustment provides a 6-15% increase in output for mid-latitude regions, but is not cost-effective for tropical regions. The conclusions of this study provide practical recommendations based on geographic zones and identify research gaps related to climate change impacts, optimization for bifacial technology, and development of economically adaptive systems.
