Abstract

Banten Province has a number of dams that have the potential to be developed as micro hydro-based renewable energy centers. Micro hydro is a technology that utilizes water flow to produce electricity on a small scale, ideal for areas with abundant water resources. The dam in Banten, which was originally built for irrigation, flood control and raw water supply, can be optimized to produce environmentally friendly electrical energy. This research uses literature study methods and secondary data analysis to evaluate the potential of dams in Banten as a micro hydro renewable energy center. The data used includes official reports, scientific publications, and data from government agencies. The analysis includes evaluation of flow capacity and water fall height, as well as the environmental impact of implementing micro hydro technology. The research results show that several dams in Banten have adequate flow capacity and water fall height to support micro hydro installations. The environmental impact of micro hydro installations can be minimized by implementing existing best practices. Micro hydro development in Banten dams can reduce dependence on fossil energy and support the national renewable energy mix target. This research recommends the development of supportive policies and the participation of local communities to realize this potential. In this way, the dam in Banten can be transformed into a renewable energy center that contributes significantly to energy security and environmental sustainability in Indonesia.

Abstract

The rapid development of information and communication technology has encouraged companies to switch to digital platforms in managing their sales. One of the most widely used solutions is a web-based sales application, which allows buying and selling transactions to be carried out online, improving operational efficiency, and expanding market reach. In this study, a web-based sales application was designed using a prototype methodology. This methodology was chosen because of its ability to actively involve users in the development process, through an iterative cycle that allows for direct feedback from users to improve and improve the system gradually. The first step in this design is to collect needs from users or stakeholders through interviews and observations. Based on these needs, an initial prototype of the application was built that included key features such as product management, shopping cart, and payment processing. The prototype is then evaluated by the user, and the feedback is used to refine and refine the prototype until the final application is ready for further development. The resulting app has a full range of features that include product management, a secure checkout system, payment method integration, and real-time sales reporting. The prototype methodology allows developers to detect and resolve potential issues from the early stages of development, thereby minimizing the risk of errors in complex feature implementations. Additionally, the active participation of users in the development process ensures that the resulting application is more in line with the needs and expectations of users. The results of this study show that a prototype-based approach can improve the effectiveness and quality of web-based sales applications, as well as maximize user satisfaction. This application is expected to help companies manage sales transactions more efficiently and expand business reach through digital platforms.
