Abstract

This community service activity aims to implement innovative learning strategies in Raudhatul Athfal Karang Jetak, Kragilan District, Serang Regency, focusing on improving the basic skills of early childhood. This program has several major components, including teacher training, project-based methods, and educational technology. Teacher training increased their competence in using creative techniques and technology. In contrast, project-based methods and educational technology improved children's fundamental skills such as reading, writing, and arithmetic. The innovative strategies implemented involve the principles of constructivism, multiple intelligence theory, intrinsic motivation, and the use of technology in education. The evaluation findings demonstrate that this method improves kids' learning abilities and engagement pleasantly and efficiently. By following the procedures that have been designed, the quality of the learning process can be continuously enhanced at Raudhatul Athfal Karang Jetak

Abstract

Telah dirancang bangun alat ukur kelembaban udara berbasis sensor serat optik evanescent dengan menggunakan cladding gelatin tulang sapi. Cladding gelatin tulang sapi dibuat dengan metode hidrolisis HCl dengan variasi perendaman 2 hari dan 4 hari. Variasi panjang pengupasan cladding serat optik adalah 1 cm, 2 cm, dan 3 cm. Pengukuran kelembaban udara dilakukan di dalam humidity chamber. Sistem sensor terdiri dari laser dioda sebagai sumber cahaya, serat optik cladding tulang sapi sebagai pengindra kelembaban, fotodioda sebagai fotodetektor, mikrokontroler sebagai pengolah sinyal dan ethernet shield sebagai transmisi data nilai kelembaban melalui plafon internet  thingspeak. Kelembaban diukur berdasarkan tegangan keluaran fotodioda. Semakin tinggi kelembaban udara maka semakin tinggi tegangan keluaran fotodioda. Hasil karakterisasi sensor menunjukkan serat optik dengan panjang pengupasan 1 cm adalah yang paling optimum dalam mengindra kelembaban. Nilai sensitifitas sensor yang dirancang adalah 0,0299 V/%RH  dengan koefisien determinasi R2 = 0,977.  Persentase rata-rata kesalahan alat ukur yang dirancang adalah 2,25 % dibandingkan dengan alat ukur acuan (humidity meter). Kata kunci: kelembaban udara, sensor serat optik, evanescent, ethernet shield.
