The purpose of this research is to analyze E-voting arrangements in organizing elections in Indonesia in accordance with the principles of organizing elections in Indonesia. This research is normative legal research which bases its analysis on applicable laws and regulations that are relevant to the legal issues that are the focus of the research. The research data sources are primary data, secondary data and tertiary data which are then analyzed juridically-qualitatively and presented in descriptive form. The research results show that implementing E-voting can overcome various problems in conventional voting systems, but implementing E-voting in elections in Indonesia faces challenges in terms of the readiness of the government, election organizers (KPU), and community culture. Although E-voting offers efficiency and increased participation, clear regulations are still missing, hindering widespread implementation. The readiness of infrastructure and human resources is also an issue, considering the need for adequate training and technology. In addition, people's cultural tendencies that tend to be skeptical of new technology can influence the acceptance of E-voting. Therefore, a comprehensive study and gradual preparation are needed to optimize the implementation of E-voting.

Furniture has high added value and significant global competitiveness, largely due to the diversity of natural raw materials available in Indonesia, such as wood, rattan, and bamboo, as well as distinctive and high-quality designs. This advantage is supported by the skills and competence of the available human resources, making Indonesian furniture superior to products from other countries. Product quality is a key element in winning market competition, as it impacts customer satisfaction and loyalty. Masnur Joglo, a furniture company located on Jl. Muara Karya, specializes in producing various types of furniture from high-quality woods such as super mahogany and red teak. However, the purchasing system, which requires customers to visit the store directly and manually record prices, results in inefficiencies in terms of time and transportation costs. Customers often need to visit multiple stores to find the desired product, which is an inefficient process. To address these challenges, this study proposes the development of an Android-based sales application as a solution. This application is designed to expand Masnur Joglo's market reach and facilitate online ordering of furniture products, anytime and anywhere. The study aims to design and develop an Android-based sales information system that can enhance operational efficiency and streamline the sales process while better meeting customer needs. The application development method employs the waterfall model and uses MySQL and Firebase databases.

Coal mining activities often result in acid mine drainage (AMD), which can cause environmental pollution if not properly managed. This study aims to evaluate the potential use of fly ash from the Stream Power Plant (PLTU) Tenggarong to mitigate the impacts of AMD, specifically targeting iron (Fe), manganese (Mn), and pH parameters. Acid Mine drainage is formed when sulfide minerals oxidize, producing acidic compounds that can harm the environment. This research focuses on analyzing the ability of fly ash to adsorb iron and manganese from AMD solutions, as well its capability to increase solution pH. Based on the conducted research, the optimum pH value was achieved when using 10 grams and 15 grams of fly ash in the adsorption process. The optimum concentration of iron (Fe) was attained using 10 grams to 15 grams of fly ash, while for manganese (Mn), it was achieved with 20 grams to 25 grams of fly ash. The adsorption process using 25 grams of fly ash showed the highest efficiency in reducing iron (Fe) concentration by 93.78 % and manganese (Mn) concentration by 75.47 %.
