Abstract

Information technology has supported the development of quality school services throughout the world. However, there are still many schools that have not used it optimally, especially in Indonesia, for example at Prince Jayakarta Bekasi Middle School. As in general, schools only use Ms. Word and Ms. applications . Excel. This resulted in different assessment formats and errors when filling in grades into the report card format. The academic information system application developed in this study uses the PHP, HTML, and MySQL programming languages and is named SIAP, which means eighteen academic information systems. The purpose of making this application is so that students / parents of students can receive school assessment information in a precise, fast and accurate manner. Teachers can also use the facility to process student scores so that they are well integrated and summarized as data for the Principal to make policies. This application can be opened on any browser platform, making it easier for users to access it anywhere and anytime.

Abstract

Plantation communities in rural Indonesia, particularly in Pangalengan Village of Bandung Regency, predominantly rely on conventional sales channels such as direct transactions with middlemen, which result in uncompetitive pricing and limited market access. Although most farmers already own smartphones and use WhatsApp daily, low digital literacy prevents them from utilizing these tools for business development. This community service activity aimed to enhance the digital business capacity of village plantation farmers through hands-on training on WhatsApp Business and online marketplaces. The implementation method comprised four stages: needs analysis, socialization (Day 1), practical training (Day 2), and evaluation. Fifty participants from Pangalengan Village joined the two-day training program. Results indicate substantial improvement in participants’ digital literacy: 92% successfully created active WhatsApp Business accounts with product catalogs, and 76% uploaded at least one product to Tokopedia or Shopee. The average pre-test score rose from 34 to 81 (out of 100) on the post-test. The activity successfully shifted participants’ marketing approach from traditional to digital, expanding market access and reducing dependence on middlemen.

Abstract

The development of Air Conditioner technology to stabilize the temperature and humidity of the air in a room has affected human life activities. This research designed an automatic control system for air conditioning using the Fuzzy Mamdani method, because it is known that air conditioners have the largest cost burden compared to other electronic devices. Then, this research designed a control system consisting of a DHT22 Sensor as an input to detect the room temperature controlled by the ESP32. Furthermore, the results of data collection are analyzed using the Fuzzy Mamdani method so that the defuzzification output instructs the relay to take action, namely switching off to adjust the temperature degree and display data to the IoT platform, ThingSpeak. The results of this research show that the DHT22 sensor test was successfully calibrated with a hygrometer comparator with an error value of 0.4%. Then, the prototype design based on fuzzy rules has been successfully implemented with an error value of 9.2% from the manual comparison so that it is concluded that the deviation difference is still recommended. This indicates that the system effectively maintains desired environmental conditions while improving energy efficiency by reducing unnecessary AC usage. The results confirm the feasibility of implementing IoT-based fuzzy control systems for practical energy-saving applications.

Abstract

Kekerasan seksual terhadap perempuan masih menjadi isu sosial yang mendapat perhatian serius di Indonesia. Dalam beberapa tahun terakhir, X menjadi salah satu platform tempat masyarakat menyampaikan opini, berbagi pengalaman, dan berdiskusi mengenai isu ini. Penelitian ini bertujuan menganalisis sentimen publik serta mengidentifikasi topik utama dalam percakapan terkait kekerasan seksual terhadap perempuan di Indonesia selama periode 2020 hingga 2025. Sebanyak 12.760 tweet dikumpulkan melalui proses crawling dan diproses menggunakan teknik pra-pemrosesan teks. Analisis sentimen dilakukan dengan algoritma Naïve Bayes, sedangkan ekstraksi topik menggunakan metode Latent Dirichlet Allocation (LDA). Hasil menunjukkan bahwa sentimen negatif mendominasi dengan proporsi 75,8%, disusul sentimen positif sebesar 15,9% dan sentimen netral sebesar 8,3%. LDA menghasilkan lima topik utama yang mencerminkan reaksi publik, isu hukum, pengalaman pribadi, serta berbagai bentuk kekerasan yang dibahas warganet. Temuan ini memberikan gambaran mengenai persepsi publik dan dapat menjadi dasar dalam penyusunan kebijakan yang lebih responsif terhadap perlindungan perempuan.

Abstract

This study analyzes the effect of Dividend Payout Ratio (DPR), Return on Assets (ROA), and Debt to Equity Ratio (DER) on the stock prices of mining companies listed on the Indonesia Stock Exchange (IDX) during 2021–2024. Stock price reflects firm value and investors' perceptions of a company's performance and prospects. The mining sector was selected because of its capital-intensive nature, high risk, and strong dependence on global commodity price fluctuations, which require comprehensive fundamental analysis. The study employs a quantitative approach using panel data regression. Secondary data were obtained from the annual financial statements of mining companies and stock price data published by the IDX. Sampling used a purposive technique, selecting companies consistently listed and publishing complete financial reports during the period, yielding 18 companies and 72 panel observations. Data were processed using EViews through the Common Effect, Fixed Effect, and Random Effect Models, with the best model determined by the Chow, Hausman, and Lagrange Multiplier tests. The Fixed Effect Model was selected. The results show that ROA has a positive and significant effect on stock price, while DPR and DER have no significant effect; simultaneously, the three variables significantly affect stock price. The study contributes to accounting and finance literature on fundamental analysis using panel data and provides a reference for investors and management in investment and financial decision-making.
