Abstract

In daily life, plastic waste feels very close to us as humans. This type of waste is very difficult to decompose,which significantly disrupts both life on land and in the ocean. In this study, the use of heated plastic waste as an additive incement mixtures for making paving blocks is still rarely explored. The aim of this research is to examine the impact of usingplastic waste as an additive in cement mixtures. Additionally, the use of plastic waste as an additive in cement is based on theidea that plastic waste can be transformed into something useful to reduce the troubling amount of plastic waste. For this purpose,this study employs both the Literature Review Method and the Experimental Method to determine how the addition of plasticwaste in paving block mixtures affects the compressive strength of the paving blocks. In this study, plastic waste will be used asan additive to cement with the following compositions: 0% (ordinary concrete), 2.5%, 5%, and 7% of the cement weight. Theresults showed that paving blocks with a 2.5% plastic mixture achieved the highest compressive strength of 26.2 MPa at 21 days,while the highest water absorption was observed in the 5% plastic mixture, with a value of approximately 6.14%. Overall, thetotal strength exceeded the planned compressive strength of 20 MPa based on the SNI 03-0691-1996 standard, making it suitablefor road use with a B quality grade.

Abstract

Overheating can significantly reduce the efficiency and power output of solar panels, leading to the development of various cooling techniques. This paper compares four cooling methods: heatsink with fan, fin heatsink, water cooling, and floating solar panels. The study evaluates these methods based on temperature reduction, cooling efficiency, electrical performance, and practical considerations. Active systems, like water cooling and heatsink with fan, showed higher performance improvements but required more resources and were more complex to operate. On the other hand, passive systems such as fin heatsink, and floating panels offered simpler and more sustainable solutions with moderate efficiency gains. This review highlights the balance between efficiency, sustainability, and practicality, providing valuable insights for choosing the best cooling method for solar panels. The findings also point to future opportunities for advancements through hybrid systems and new materials to enhance performance and sustainability in solar energy systems.

Abstract

Dye-Sensitized Solar Cells (DSSCs) have garnered significant attention due to their cost-effectiveness and potential for sustainable energy applications. TiO2 and ZnO nanostructures are widely employed as photoanodes, given their unique optical and electronic properties. This paper compares the findings of ten studies with similar research scopes, highlighting enhancements in DSSC efficiency using modified TiO2 and ZnO. Results are presented through comparative analysis and graphical representations, focusing on energy conversion efficiency. Through a detailed comparative analysis, this research identifies key trends and material innovations for advancing DSSC technology. Currently from these studies TiO2 with synthesis dye still hold the highest efficiency compared to ZnO and Synthesis TiO2/ZnO nanocomposite whether using synthesis and natural dye and by using counter electrode of Mg and Fe in TiO2 based have the least efficiency. DSSCs efficiency still lower than silicon based and thin-film solar cells but have the potential to be the cheapest solar cells. DSSCs need to improve efficiency to be able to go to marketplace and it needs further research and combination of dye and counter electrode or even the new breakthrough.

Abstract

Desa Bungin, located in the Paringin Selatan District of Balangan Regency, has begun adopting information technology to enhance administrative activities. However, administrative management at the Desa Bungin Office still faces several challenges, including manual record-keeping, reliance on hard-copy archives, and dependence on a centralized system without an integrated information system. These limitations result in inefficiencies in time management, an increased risk of errors, and obstacles to providing optimal administrative services to the community. To address these issues, this study proposes an enterprise architecture framework to align business functions with information technology needs. The TOGAF ADM approach is employed as a structured methodology for developing an integrated architectural blueprint. This study focuses on three key phases of TOGAF ADM: the Preliminary Phase, Architecture Vision, and Business Architecture, with a strong emphasis on Business Architecture design. Business Architecture plays a crucial role in structuring and analyzing business processes, identifying key actors, and understanding interactions within the organization. This research examines essential elements such as workflows, resources, and inter-process relationships. The findings present a well-structured Business Architecture model that serves as the foundation for developing a comprehensive Enterprise Architecture. This framework is expected to enhance efficiency, streamline administrative processes, and support the digital transformation of Desa Bungin’s governance.

Abstract

In the modern era, characterized by an increasing demand for mobility and energy efficiency, fast-charging technology plays a crucial role. As the use of electronic devices and electric vehicles continues to rise, the need for more efficient and energy-saving charging systems is also growing. One of the key components in these systems is the lead-acid battery and capacitor bank, both of which have the ability to store and release energy quickly. Therefore, these components are essential in enhancing the effectiveness of the charging process. However, a major challenge in fast charging systems is optimizing the configuration of lead-acid batteries and capacitor banks to minimize charging time while reducing power losses during the process. Addressing this challenge requires an intelligent approach to determining the optimal power distribution path to ensure a stable and efficient charging process. This study utilizes the Ant Colony Optimization (ACO) algorithm to optimize the configuration of lead-acid batteries and capacitor banks in a fast-charging system. The natural behavior of ant colonies inspires the ACO algorithm to search for the shortest path to a food source. This method has been proven effective in solving various complex optimization problems, including power distribution and energy charging. By implementing this algorithm, the system can identify an optimal charging pattern, reducing voltage fluctuations and maximizing energy efficiency throughout the charging process. The primary goal of this research is to develop a fast charging system that is more efficient, energy-saving, and capable of operating optimally under various conditions. By optimizing the use of lead-acid batteries and capacitor banks through the application of the ACO algorithm, this system is expected to accelerate the charging process without compromising reliability and battery lifespan. The findings of this study are anticipated to contribute to the advancement of smarter charging technology, supporting high mobility needs in the modern era, and providing a more sustainable solution for energy management.

Abstract

Parking in dense urban areas is a big challenge because the increase in the number of vehicles causes a shortage of parking spaces, congestion and air pollution. As the number of vehicles increases, parking space is needed to accommodate many vehicles. Limited land often results in illegal parking which has a negative impact resulting in traffic jams. Rotary parking is one solution to maximize the use of limited parking space more efficiently. To move rotary parking, a DC motor is needed. In this rotary parking design, which has a capacity of 20 kg, a DC shunt wiper motor with a power capacity of 10-50 watts, 12VDC, and a current of 1-4 Ampere was chosen. This system is equipped with RFID technology to ensure safe vehicle access. The test was carried out eight times with gradual loads ranging from 16.5 kg to 20 kg. The results show that the tool can work well at each stage, with output power ranging from 14.46 watts at a load of 16.5 kg to 12.76 watts at a load of 20 kg. In conclusion, this rotary parking system can work as expected, efficiently handling the carload and a total load of 20 kg, as well as providing additional security using RFID and easy monitoring via IoT.

Abstract

This conceptual paper proposes a structured framework for managing junior faculty mentoring in higher education institutions (HEIs), with a focus on the Vietnamese context. While mentoring is globally recognized as a core faculty development strategy, its implementation in systems such as Vietnam remains largely informal, fragmented, and weakly integrated into institutional management structures. To address this gap, the study draws on Human Resource Development (HRD), Organizational Learning (OL) theory, and Social Exchange Theory (SET), combined with a review of international mentoring models and the specific characteristics of Vietnam’s higher education environment. The proposed framework comprises six interrelated components: Inputs, Core Processes, Management Layer, Outputs, Evaluation and Feedback, and Contextual Factors. These components are designed to align mentoring activities with institutional development priorities while reflecting cultural and governance realities. The framework emphasizes centralized coordination alongside departmental flexibility, formal mentor and mentee relationships supported by institutional incentives, and continuous evaluation mechanisms adapted to Vietnam’s regulatory context. Although conceptual in scope, the framework offers a theoretically grounded and practice-oriented basis for managing mentoring in Vietnamese HEIs. It provides actionable insights for institutional leaders, policy-makers, and faculty members, while contributing to mentoring literature through its focus on management-oriented approaches in non-Western higher education systems.
