Abstract

Penelitian ini bertujuan untuk merancang dan membangun sebuah prototipe alat pendeteksi kadar gula darah non-invasif portabel berbasis Internet of Things (IoT). Metode yang digunakan adalah photoplethysmography (PPG) dengan sensor MAX30100 pada mikrokontroler ESP32 untuk merekam fluktuasi sinyal Inframerah dan Merah dari ujung jari. Data sinyal mentah yang diperoleh kemudian diolah untuk mengekstrak fitur-fitur kunci, meliputi detak jantung (BPM), saturasi oksigen (SpO2), rasio AC/DC IR, dan rasio AC/DC Red. Fitur-fitur ini, bersama dengan data usia subjek, dianalisis menggunakan model regresi linear multivariat untuk mengestimasi kadar glukosa darah. Sistem ini dilengkapi dengan LCD untuk menampilkan hasil, serta modul SD Card dan konektivitas WiFi untuk penyimpanan data ganda ke data logger lokal dan Google Sheets. Hasil dari pengujian validasi pada 31 sampel data menunjukkan prototipe ini berhasil mencapai tingkat akurasi total sebesar 92% dengan rata-rata persentase kesalahan absolut (MAPE) sebesar 8% saat dibandingkan dengan glukometer standar. Kinerja terbaik tercatat pada mode "Setelah Makan" dan "Sewaktu", namun akurasi menurun pada mode "Puasa", terutama pada subjek di atas 40 tahun. Penelitian ini berhasil membuktikan kelayakan konsep metode estimasi glukosa berbasis fitur PPG. Disarankan untuk melakukan validasi lanjutan dengan sampel yang lebih besar dan eksplorasi model machine learning non-linear untuk meningkatkan generalisasi model.

Abstract

This community service activity aims to design and implement a solar panel-based Emergency Box as a learning medium and emergency power supply solution at the Raudlatul Ulum Islamic Boarding School, Kalisat, Jember. This activity was motivated by limited electrical facilities and minimal learning practice facilities within the Islamic boarding school environment. The implementation method included literature study, needs analysis, system design, tool assembly, and outreach and mentoring activities for teachers and students. The results of the activity showed that the designed Emergency Box was able to function optimally as an alternative power source for lighting and charging electronic devices. Through training and mentoring, teachers and students gained an understanding of the working principles of solar energy as well as technical skills in operating and maintaining the device. This activity is expected to improve the quality of practice-based learning and raise awareness of the importance of using renewable energy in the Islamic boarding school environment
