Abstract

Solar panels are alternative energy that utilizes the intensity of the sun as its energy source. The EBT (Renewable Energy) Laboratory of Electrical Engineering at the University of Mataram is currently still measuring conventionally using a multimeter. Measurements are carried out with the aim of recording the output of solar panels. It takes a tool to be able to measure the output of solar panels continuously and in realtime so that the energy obtained by solar panels can be known with certainty. The tool is made using a current sensor, voltage sensor, and temperature sensor and a microcontroller as a control to retrieve sensor data and then send it to the database using the MQTT protocol. Data on the database is presented in the form of a fuzzy database system and fuzzy queries are performed on the system. Data is collected from 08.00 to 17.00 for one week to get more accurate data. The measurement results and analysis will be displayed in the form of line diagrams with the WEB interface.

Abstract

Desa Gumantar, yang terletak di Kabupaten Lombok Utara, menghadapi tantangan besar dalam sektor pertanian karena kondisi lahan yang kering dan cuaca panas ekstrem. Rendahnya curah hujan dan distribusi air yang terbatas mengakibatkan kesulitan dalam pengelolaan sumber daya air, yang berdampak negatif pada produktivitas pertanian. Untuk mengatasi permasalahan ini, teknologi irigasi hemat air seperti sistem irigasi tetes sangat diperlukan untuk memaksimalkan penggunaan air secara efisien. Selain itu, pemanfaatan tenaga surya sebagai sumber energi alternatif dapat mendukung keberlanjutan pertanian dengan mengurangi ketergantungan pada bahan bakar fosil. Dalam kegiatan pengabdian masyarakat ini, dilakukan instalasi sistem irigasi tetes yang digerakkan oleh tenaga surya pada lahan pertanian di Desa Gumantar. Sistem ini menggunakan panel surya untuk menggerakkan pompa air yang menyalurkan air melalui pipa langsung ke akar tanaman. Hasil implementasi menunjukkan pengurangan biaya operasional yang signifikan, khususnya dalam pengeluaran solar, serta peningkatan produktivitas tanaman tomat dan cabai. Teknologi ini tidak hanya meningkatkan efisiensi penyiraman tetapi juga memberikan pengetahuan dan keterampilan baru kepada petani mengenai teknologi irigasi berkelanjutan yang ramah lingkungan dan efisien.

Abstract

This study aims to evaluate the acceptance of IoT-based toddler scales by cadres and health workers at Posyandu by applying the Technology Acceptance Model (TAM). A total of 50 respondents were involved, and the collected data were analyzed using SmartPLS to test the influence of TAM variables on technology acceptance. The analysis revealed that attitude (ATU) was able to explain 63.7% of the variance, indicating that a positive attitude towards technology is a major factor in acceptance. Furthermore, perceived benefits (PU) contributed 57.1%, indicating that respondents adequately recognized the advantages of IoT-based scales. Behavioral intention (BI) also exerts a moderate influence with a contribution of 53.1% of the variance in technology use. However, actual use (AU) only reached 26.5%, indicating a significant gap between intention to use and implementation of the technology in the field due to resistance in the form of concerns related to potential labor reduction. countfor lte to This finding confirms that while the benefits and attitudinal aspects support technology adoption, external factors such as fear of job loss remain barriers to actual implementation.
