Abstract

Clean water availability is a fundamental need that plays an important role in supporting educational activities, environmental hygiene, and the implementation of religious activities in schools. SD Islam Fitra Bhakti faced limited clean water supply caused by insufficient water tank capacity and an inadequately managed water distribution system. This condition disrupted sanitation activities and routine worship practices of students and teachers, particularly during peak water usage periods. This Community Service Program aimed to improve the availability and reliability of clean water supply through the application of appropriate technology that is simple, effective, and suitable for partner conditions. The implementation methods included needs assessment and analysis, technical solution design, installation of the water supply system, as well as training and assistance for school staff. The implemented solution consisted of adding water storage tanks, installing a PDAM-based water supply system, and applying an automatic stop valve to control water flow into the tank. The results indicate that the implemented system successfully increased water storage capacity and ensured a more stable continuity of clean water supply. In addition, school staff demonstrated improved understanding and independence in operating and maintaining the system after the training was conducted. The application of this appropriate technology had a positive impact on water management efficiency and supported the long-term sustainability of school operations.

Abstract

Vegetable farmers in Bebengan Village, Kendal Regency, still mostly water their crops manually, resulting in inefficient water usage and inconsistent watering timing. Additionally, the water quality for irrigation has not been monitored regularly, even though pH and PPM parameters affect nutrient availability and plant growth. This service activity aims to implement an Internet of Things (IoT)-based automatic plant watering technology that can monitor pH and PPM and provide easy control through Google Assistant. The implementation methods include observing partner needs, designing and assembling an Arduino ATmega 2560 and ESP8266-based system with pH and PPM sensors, installing it on a 200 m² cultivation area, integrating remote monitoring and control, and training farmers on operating and maintaining the equipment. Implementing the system allows for more scheduled/controlled watering and provides real-time pH and PPM information as a basis for decision-making. In conclusion, the implementation of this IoT system improves the effectiveness of the watering process, supports water quality monitoring, and simplifies operations through voice-based control, thus potentially increasing cultivation efficiency at the farmer level.

Abstract

The development of sixth-generation (6G) wireless networks has encouraged the utilization of millimeter-wave (mmWave) spectrum to support extremely high data rates and network capacity. However, signal propagation at mmWave frequencies is highly susceptible to multipath effects and severe path loss, particularly under Non-Line-of-Sight (NLOS) conditions. This study analyzes the characteristics of a 30 GHz multipath channel using the NYUSIM channel simulator and evaluates its impact on Bit Error Rate (BER) performance. Simulations were conducted in an Urban Microcell (UMi) NLOS scenario with a bandwidth of 400 MHz, employing 64-QAM modulation, Orthogonal Frequency Division Multiplexing (OFDM), and a rate-1/2 Convolutional Code. Channel characterization results indicate a path loss of 127 dB, an average received power of −96.1 dBm, and an RMS delay spread of 14.6 ns. Furthermore, the Angle of Arrival (AOA) and Angle of Departure (AOD) analyses reveal that signal propagation is dominated by reflected paths due to the absence of a direct Line-of-Sight (LOS) component. BER performance evaluation shows that increasing the Signal-to-Noise Ratio (SNR) from 0 dB to 14 dB reduces the BER from approximately 4.8 × 10⁻¹ to 9 × 10⁻³. At an SNR of 16 dB, the system achieves a BER below 10⁻³, indicating a substantial improvement in transmission reliability. The results demonstrate that the combination of OFDM and Convolutional Coding effectively mitigates the effects of multipath fading in mmWave channels, making it a promising solution for future 6G wireless communication systems operating at 30 GHz.
