Abstract

Water is one of the most fundamental basic needs for human life. However, disparities in the availability of clean water remain a significant challenge in Indonesia. This study aims to develop a water purification device to address this issue. The research method employed was the ADDIE model, which consists of five stages, with this study focusing on analysis, design, and development, which serve as scope of this study. The result of a water purification, named HydroTechPure, utilizes a dual filter system with high quality absorbent materials and is constructed from acrylic materials, enhanced by 3D design technology and Arduino integration. The development of this device aligns with the sixth goal of the Sustainable Development Goals (SDGs), which emphasizes ensuring access to clean water and sanitation for all. HydroTechPure was developed at FabLab Edu UPI. Beyond its primary function, HydroTechPure is envisioned as a tool for integrating STEM based learning, aiming to foster students’ motivation and environmental awareness.

Abstract

Tanah longsor merupakan bencana alam yang sering terjadi di Indonesia, khususnya di wilayah pegunungan seperti Kabupaten Temanggung, Jawa Tengah. Kabupaten ini memiliki dua gunung aktif, Sindoro dan Sumbing, serta tingkat kejadian longsor yang tinggi, dengan 71 kasus tercatat pada tahun 2023 hingga Februari 2025 di Kecamatan Kranggan, Kandangan, Kaloran, dan Pringsurat. Penelitian ini bertujuan memetakan tingkat kerawanan longsor menggunakan metode Frequency Ratio (FR) berbasis Sistem Informasi Geografis (SIG) dengan mempertimbangkan sepuluh parameter lingkungan. Hasil analisis menunjukkan bahwa kemiringan lereng >20% memiliki nilai FR sebesar 7,724, arah lereng barat laut FR 2,275, jenis batuan Gunungapi Gilipetung FR 3,495, dan jarak dari garis sesar 1.000–2.000 m FR 2,367, yang semuanya berkontribusi signifikan terhadap kerentanan longsor. Pemetaan zona kerawanan menggunakan Jenks Natural Breaks menghasilkan tiga zona: rendah (LSI 2,39–8,60), sedang (LSI 8,60–12,07), dan tinggi (LSI 12,07–19,41), dengan zona tinggi mendominasi bagian utara Kaloran dan timur Kandangan. Validasi model menggunakan Area Under Curve (AUC) menunjukkan Success Rate sebesar 0,875 dan Prediction Rate 0,682, menandakan akurasi yang baik. Penelitian ini menegaskan bahwa metode FR efektif dalam mengidentifikasi zona rawan longsor serta menjadi dasar penting untuk mitigasi bencana dan perencanaan tata ruang di Kabupaten Temanggung.
