Abstract

One of the factors affecting crop yields is the condition of nutrients in plants. The nutrient condition, particularly nitrogen, can be identified through the chlorophyll content in plant leaves, which can be measured using a chlorophyll meter. However, current chlorophyll meters are still expensive and have limitations such as limited data storage, with data being lost if there is no power supply. In this paper, an ESP32-based chlorophyll meter was developed to store chlorophyll content index (CCI) data in a memory module, enabling the data to be used for nitrogen status analysis. The plant used for chlorophyll measurement in this study was the jumbo sugar apple plant. The research methods included literature reviews from previous studies, design, implementation, and performance testing of the ESP32-based chlorophyll meter compared to the TYS-A chlorophyll meter in measuring the chlorophyll content of jumbo sugar apple leaves. The test results showed a determination coefficient (R²) of 0.9517 between the TYS-A values and those of the ESP32-based chlorophyll meter, indicating a significant correlation. The ESP32-based chlorophyll meter functioned effectively, being capable of measuring the chlorophyll index of jumbo sugar apple plant and storing the chlorophyll index data in a memory module. The ESP32-based chlorophyll meter can serve as an affordable alternative to the TYS-A chlorophyll meter.

Abstract

Abstract:  As artificial intelligence technology advances, teachers must become more proficient in addressing existing issues. Therefore, the goal of this program is to increase teachers' ability to meet the opportunities and challenges presented by the artificial intelligence-based learning era. As technology advances quickly, educators must become more creative, adaptable, and digitally literate, particularly when it comes to incorporating AI into the classroom. Kindergarten, elementary, middle, and high schools in the cities of Jakarta, Surabaya, Pekanbaru, and Jambi are overseen by the Pancaran Metta Paramita PKBM Foundation Guang Ming. Teachers at Guang Ming's school served as training participants in the creation of learning resources, the creation of questions, and the analysis of student work. The activity was carried out through the use of Participatory Action Research (PAR), in which participants received instruction and helpers to aid in their learning as they practiced. According to questionnaire results, participants felt that the PKM's content was in line with their needs, that the implementation period was excellent, that the speakers' content was excellent, that the participants understood the material, and that the PKM activity space was sufficient, receiving a very good rating of between 71.4% and 90.5%.Abstrak: Seiring kemajuan teknologi kecerdasan buatan, guru harus menjadi lebih mahir dalam mengatasi masalah yang ada.

Seiring kemajuan teknologi dengan cepat, para pendidik harus menjadi lebih kreatif, mudah beradaptasi, dan melek secara digital, terutama ketika datang untuk memasukkan AI ke dalam kelas. TK, SD, SMP, dan SMU di Kota Jakarta, Surabaya, Pekanbaru, dan Jambi diawasi oleh Yayasan Pancaran Metta Paramita PKBM Guang Ming. Guru di Sekolah Guang Ming menjabat sebagai peserta pelatihan dalam penciptaan sumber belajar, penciptaan pertanyaan, dan analisis pekerjaan siswa. Metode yang digunakan Participatory Action Research (PAR), di mana peserta menerima instruksi dan pembantu untuk membantu dalam pembelajaran mereka saat mereka berlatih. Menurut hasil kuesioner, peserta merasa bahwa konten PKM sejalan dengan kebutuhan mereka, bahwa periode implementasi sangat baik, bahwa konten pembicara sangat baik, bahwa para peserta memahami materi tersebut, dan bahwa ruang aktivitas PKM sudah cukup, menerima peringkat yang sangat baik antara 71,4% dan 90,5%.
