Abstract

The Bantar Gebang Integrated Waste Treatment Site (TPST) is one of Indonesia's largest final disposal sites. The increasing generation of waste daily can cause methane (CH4) and carbon dioxide (CO2) emissions. Methane and carbon dioxide are greenhouse gases that can cause global warminag and endanger respiratory health at specific concentrations. Therefore, the authors created an IoT-based CH4 and CO2 gas monitoring system using the ESP32 as a microcontroller, the MQ-4 sensor to measure CH4, and the MG-811 sensor to measure CO2. The tool's design is simple and portable, with a 20x4 LCD, and the Blynk website can store data via an SD card. After testing, the tool can operate properly, and the results of CH4 and CO2 gas concentrations at the Bantar Gebang TPST location are around 2.01 ppm and 419.89 ppm with regular status.

Abstract

Rivers have an important role in the lives of Indonesian people, as they function as resources that are used for various purposes. When rivers are utilized wisely and accompanied by awareness of protecting the environment, the water quality can be maintained properly. This study aims to monitor river water quality in the Pesanggrahan river basin. The river water samples are then analyzed using various water quality parameters so that the resulting data is expected to help the Indonesian people understand the condition and quality of river water and optimize efforts to protect the environment. In this research, the designed tool includes several sensors and other components. DS18B20 sensor is used to measure water temperature, analog pH meter sensor is used to measure pH levels, TDS meter sensor is used to measure water salinity, and analog turbidity sensor is used to measure water turbidity. In addition, the ESP32 wireless communication module and Arduino ATMega2560 microcontroller are used to process and transmit data generated by these sensors. This system can be monitored remotely through a smartphone using the internet of things through the Blynk application in real-time. In addition, the data can also be disseminated through Telegram Bot so that users can easily access and monitor water quality data through smartphones.

Abstract

This paper presents the redesign, rebuild, and rebranding of the official website of Sekolah Tinggi Meteorologi Klimatologi dan Geofisika (STMKG) using the WordPress content management system. The project aimed to modernize the institution’s digital presence by enhancing layout consistency, mobile responsiveness, and brand identity. A content audit was conducted to reorganize fragmented navigation and outdated information. The entire development was executed directly within WordPress using Elementor, enabling rapid prototyping without external wireframing tools. Key improvements include structured program sections, a modern news layout, and a standardized footer, all designed in line with STMKG’s visual identity. Performance optimization—though not the primary focus—involved basic caching, compression, and lazy loading, with assessments via GTmetrix indicating areas for future improvement. The project, completed by a sixth-semester cadet, highlights the feasibility of student-led web transformation initiatives within academic institutions. Positive stakeholder feedback confirmed improvements in usability, clarity, and institutional credibility. This work demonstrates the practical application of accessible web technologies to deliver scalable, branded, and user-centered digital solutions in educational settings.
