Acknowledging the issue of energy sustainability, the sugar industry has begun to look at plans to sell electricity to address energy sustainability issues. A scenario with the potential to sell excess electricity motivates this research to analyze the strategies of the sugar industry development. In such situations an ANP approach is applied for the selection of appropriate strategies. This study analyzes the potential for electricity sales in two alternative plant development strategies of three sugarcane industries which from the results, Strategy A (cogeneration scheme) allows to sell electricity for 223-293 days while strategy B (independent power plant scheme) allows to sell throughout the year. The result also shows that by using ANP, it is found that strategy A is better than strategy B

The Arduino UNO, ultrasonic sensor, servo motor, and Processing as visual software was used to create a low cost ultrasonic radar system that can detect and determine the location of an object, such as obstacles, in a short distance. Objects can be sensed up to 40 cm away from the ultrasonic sensor and the ultrasonic radar's angular rotation can detect objects from 15o to 165o and counterclockwise. The obstacle objects will be displayed in the computer panel by running the visual software. A comparative analysis of the distance error between the radar and the obstacles is used to assess the feasibility of the proposed system. The findings obtained from measurements of the obstacles are tabled to show that the planned design achieved a relatively small error, with 90% as the lowest accuracy.

Perkembangan sains di dunia sangat pesat, sehingga membutuhkan pemahaman yang cepat dan tepat. Institut Teknologi Sumatera merupkan salah satu institut teknologi di Sumatera, sehingga keberadaanya menjadi pusat pengembangan sains dan teknologi. Salah satu topik yang menarik untuk dikembangkan adalah sensor, salah satunya biosensor. Polimer konduktif merupakan salah satu jenis biosensor yang mudah untuk digunakan dan dibuat. Untuk mempercepat riset dalam nanoteknologi, pengenalan pengetahuan dasar sangat penting. Pengenalan lebih awal akan mempermudah dalam meningkatkan pemahaman siswa dan tenaga pendidik di sekolah. Guru dan siswa Sekolah Menengah Atas (SMA) merupakan sasaran yang paling tepat untuk melihat tingkat pemahaman sebelum melanjutkan ke tingat yang lebih tinggi (Universitas). Pengukuran tingkat pemahaman dilakukan melalui pengisian kuisioner sebelum dan setelah pelaksanaan kegiatan. Hasil Kuisioner menunjukkan bahwa 30-35 % dari total peserta belum memiliki pengetahuan mengenai polymer conductive sebelum workshop dilaksanakan.. Pengetahuan peserta meningkat menjadi 89 % setelah materi diberikan.

This research discusses the implementation of a prototype system to detect leaks in water pipes using water flow and ultrasonic sensors, applied to a web-based Internet of Things (IoT) for real-time monitoring. The aim of this research is to identify pipe leaks analyzed against flow rate and pressure. The system is designed considering the system design analysis using hardware, software, and web interface design for data visualization and control. The results of this study show that the water flow and ultrasonic sensors have high accuracy and precision with low error rates. Functional testing of the system was carried out through several experiments, both with and without leaks, and showed that the system works well in monitoring flow rates and water levels. However, some discrepancies were found in the readings during leak testing, indicating the need for further evaluation of the sensor code. Overall, this research was successful with real-time data accessible through the web interface.

Oil pipeline leaks pose a serious challenge due to their potential to cause significant economic losses and severe environmental damage. These incidents can disrupt industrial operations and endanger nearby ecosystems and communities. Early detection and real-time monitoring are therefore essential for minimizing adverse impacts and enabling rapid response. This research develops an Internet of Things (IoT)-based oil pipeline leak monitoring system using integrated multi-sensor data collected from field-simulated scenarios, providing a realistic evaluation of system performance under near-operational conditions. The system incorporates an ultrasonic sensor (HC-SR04) to measure fluid levels, a temperature sensor (DS18B20) to detect thermal anomalies, and a pressure sensor to identify internal pressure fluctuations. Sensor data are wirelessly transmitted via a NodeMCU ESP32 microcontroller to a web-based dashboard for remote monitoring, while local readings are simultaneously displayed on an LCD screen for on-site observation. The system was evaluated through controlled experiments simulating variations in pressure, temperature, and induced leak conditions. Results showed that the system achieved over 95% accuracy in leak detection, with a response time of less than 60 seconds upon leak initiation. The flow rate deviations under leak conditions exceeded the ±3% detection threshold, triggering real-time alerts. In non-leak scenarios, flow rates remained steady between 1.5–2.1 L/min, with tank level variations within 1 cm, confirming strong mass balance and stability. Overall, the developed IoT-based monitoring platform demonstrated high reliability and effectiveness in real-time leak detection, enabling faster response and significantly reducing potential environmental and operational impacts.
