Abstract

Permasalahan yang ada pada server adalah banyaknya user yang mengakses dalam waktu bersamaan. Untuk mengatasinya dapat digunakan konsep cluster server. Metode yang digunakan dalam artikel ini adalah membangun 3 cluster server web  dan 1 load balancer dari 4 buah Nanopi2 serta  mengimplementasikan algoritma round robin dalam pengaturan kerjanya. Hasil yang diperoleh adalah bahwa terjadi pembagian beban trafik yang berimbang di antara 3 server dengan rata-rata pada saat server menerima request dari client adalah 33.57%, 32.64%, dan 33.8%, serta rata-rata pada saat server memberikan response adalah 33.47%, 34.14%, dan 35.35%

Abstract

Grape cultivation has gained increasing attention due to its short growing period and the high market value of its sweet, refreshing fruits. However, achieving optimal growth requires precise environmental and nutrient management, which can be challenging under conventional farming practices. This research aims to develop an automatic watering system that integrates soil moisture and nutrient monitoring to optimize grape cultivation. The system utilizes Nitrogen Phosphorus Potassium (NPK) sensors, soil moisture sensors, and a camera for growth observation, all connected through the internet of things (IoT) for remote monitoring via Android devices. A fuzzy logic controller is implemented to regulate watering duration based on environmental conditions such as temperature and humidity. Experimental results show that the system effectively adjusts watering duration to approximately six seconds when the temperature is between 25–32 °C and humidity is around 60%. The DS18B20 temperature sensor achieved an average error rate of only 0.12%, while the humidity sensor demonstrated 0.2% error, indicating high accuracy levels of 99.8%. Despite minor limitations related to internet stability and sensor calibration, the system demonstrates strong potential for commercial-scale smart farming applications, promoting resource-efficient and data-driven grape cultivation.

Abstract

Bandungrejosari Village RT.05/RW.09, located in Sukun District, Malang City, is vulnerable to flooding due to its proximity to a river and has also faced increasing motorcycle theft. These conditions have raised community concerns and emphasized the need for preventive measures through technology. This program introduced the installation of Closed Circuit Television (CCTV) to support flood mitigation and strengthen neighborhood security, while also providing technical training and awareness on technology-based monitoring systems. The implementation followed a participatory and educational approach, involving stages of preparation, planning, training, installation, and evaluation. Residents actively participated in site surveys, practical device installation, and system simulations, ensuring community ownership of the initiative. Evaluation was conducted through direct observation and questionnaires distributed to 30 respondents. The results indicate that CCTV installation at strategic points effectively assisted in monitoring river conditions and areas prone to crime. Most residents expressed satisfaction, felt supported, and showed willingness to maintain the system. Overall, the program not only improved community preparedness and security but also enhanced collective awareness and participation in sustaining technological solutions for local challenges.

Abstract

This study presents the design and performance evaluation of a LoRa-based Wireless Sensor Network (WSN) prototype for data transmission in a Smart Waste Bank system operating in a semi-urban environment. The proposed system adopts a hybrid network architecture, combining multi-hop communication among sensor nodes with a star topology for long-range transmission to a Raspberry Pi–based sink node. An ESP32 microcontroller integrated with a LoRa SX1278 module operating at 433 MHz is used to transmit waste volume and activity data with low power consumption. Unlike prior studies that predominantly focus on generic LoRa performance evaluation, this research provides a contextual and application-driven assessment of LoRa-based WSN communication tailored to community-scale Smart Waste Bank operations under non-line-of-sight conditions. System performance was evaluated using RSSI, SNR, and PDR at transmission distances ranging from 10 m to 1000 m. Experimental results show that RSSI decreases from −56 dB to −112 dB and SNR from 6.3 dB to 1.0 dB as distance increases, while the system maintains reliable communication with an average PDR of 97% up to 800 m. Distinct from existing LoRa performance studies, this work explicitly integrates a hybrid multi-hop and star WSN topology within a real-world smart waste bank deployment, providing empirical communication benchmarks that are directly applicable to community-scale IoT implementations rather than controlled or generic test scenarios.
