Abstract

This paper discusses the water management conducted by Telkom University, including the fundamental considerations to be taken into account, the implementing organization, the design methods for rainwater systems, and practical experiences in constructing Rainwater Harvesting systems. The management is aware of the conditions and situations related to clean water users, estimates of clean water requirements, potential water sources, and the campus environmental situation. Based on various studies and supported by rainfall data from the Meteorology, Climatology, and Geophysics Agency, a simple calculation was used to derive the design of the Rainwater Harvesting system, which was subsequently implemented. There are several lessons learned from this implementation, including the need for improvements in the foundation structure of soak pits, recommending the construction of ground tanks during the dry season, and the flexibility of ground tank size depending on the availability of funds The abstract should state briefly the purpose of the research, the principal results and major conclusions.

Abstract

In 2045, Indonesia is projected to become a developed country, with the 4th largest economy in the world. This prediction is motivated by the demographic bonus that will occur in 2030-2040. This is an advantage if you succeed in educating the younger generation. On the other hand, it will be a "disaster" if the quality of Indonesian society is not well prepared. Indonesia is a country that has solar energy potential of 207.8 GWp and rainfall ranging from 2000-3000 mm per year. The large potential of solar energy and rainwater has not been utilized optimally. Rainwater can be a source of water that is refreshing and safe to use for daily needs. Another problem is that there are still vocational school alumni who are unemployed, so their level of welfare is still lacking. This community service program has been carried out for students and teachers at Vocational School 6 in the city of Bandung in the form of counseling and making 1000-liter rainwater harvesting storage or water ionizers using energy sources from 200-Watt solar cell modules. The results of the questionnaire show that the average agree/strongly agree score is 93.3% and the community accepts and hopes that activities like this will continue in the future

Abstract

The use of ground tank constructed by Telkom University for Rainwater Harvesting (RWH), is limited to environmental maintenance due to concerns regarding the quality of water in the underground tank. Therefore, this research aims to develop a remote monitoring device that uses Internet of Things (IoT) technology to monitor the pH, water surface, submerged materials, and water clarity levels in ground tank. To achieve the requirements, pH, ultrasonic-based volume, Total Dissolved Solids (TDS), and Turbidity sensors were selected due to the IoT connectivity. The enabling device, namely the ESP 32 microcontroller and Blynk platform were installed on monitoring dashboard on a tablet computer with 4GB of RAM. The result showed that calibration of each sensor had good accuracy, except for the Turbidity sensor due unavailable materials. In conclusion, the RWH monitoring system is suitable for use.

Abstract

Data center cooling system is consuming large amounts of power, which requires effective control to reduce operational costs and deliver optimal server performance. The high power consumption occurs because traditional cooling methods struggle to adapt dynamically to workloads, causing wasteful power consumption. Therefore, this study aimed to explore the use of machine learning methods to improve energy efficiency for data center cooling system. For the experiment, an RL (Reinforcement Learning) model was designed to adjust cooling parameters with dynamic environmental changes. The method focused on optimizing energy efficiency while maintaining stable temperature and humidity control. By applying RL-based control method to PAC system, this study contributed original results that validated the effectiveness of RL-simulated data center environments. Specifically, the stages included developing system model, creating simulations using the PAC control system, and training an RL model with environmental conditions. Data were collected from simulations and analyzed to test the model performance, and the outcomes were presented using a real-time monitoring interface with Flask. The results showed that the RL model achieved an average reward of 4.76 (between -5 and 5), a convergence rate 13.2, a sampling efficiency 10.15, and a stability score 2.6. The model effectively reduced temperature and increased humidity during stressed data center operations. When compared with a fixed cooling system, RL showed superior adaptability to workload variations and reduced unnecessary energy consumption. However, scalability to real data center remained an issue, which required more than simulation validation. In conclusion, the RL-based method optimized efficiency of cooling system, showing the potential to improve energy savings and operational resilience in data center environments.
