Ketersediaan data spasial merupakan faktor penting bagi pelaku tanggap darurat dalam menjalankan misinya. Selama ini, sumber data utama adalah pemerintah, salah satunya melalui jaringan infrastruktur data spasial (IDS). Namun, realitanya menunjukkan bahwa pemerintah sering kesulitan dalam menyediakan data terkini pada masa tanggap darurat. Sementara itu, perkembangan teknologi Web 2.0 telah memungkinkan kerumunan daring (crowd) untuk menjadi sumber data alternatif. Kerumunan daring ada yang berkontribusi data secara aktif dan pasif. Penggabungan antara dua sumber data tersebut diyakini menjadi solusi untuk memenuhi kebutuhan data bagi petugas tanggap darurat bencana. Penelitian ini bertujuan untuk membuat sebuah usulan sistem yang dapat menggabungkan dua sumber data dari pemerintah dan kerumunan daring pada kegiatan tanggap darurat bencana. Metode untuk mencapai tujuan tersebut adalah melakukan studi pustaka, analisis kebutuhan, desain dan implementasi sistem berdasarkan rancangan skenario tanggap darurat bencana. Hasil yang diperoleh adalah sebuah rangkaian aplikasi yang mengikuti usulan sistem untuk menggabungkan data pemerintah dan kerumunan daring. Rangkaian aplikasi tersebut adalah aplikasi geoportal, aplikasi peranti bergerak, media sosial dan peta daring. Secara garis besar penelitian ini menunjukkan bahwa mengadopsi dua sumber data dapat mengatasi potensi kekurangan data pada saat tanggap darurat bencana, meskipun isu terkait kualitas data belum tuntas diatasi dalam penelitian ini. Penelitian ini dapat dimanfaatkan bagi petugas tanggap darurat bencana di Pusat Pengendalian Operasi Penanggulangan Bencana.
This study aims to create a system model that implements the concept of Geovisualization on shoreline changes in Padang city. This implementation is to make it easier to identify shoreline changes. The method used to detect changes is by interpreting satellite imagery with the Modified Normalized Difference Water Index (MNDWI) approach and the Digital Shoreline Analysis System (DSAS). The imagery used is Landsat 7 and Landsat 8 from 2000 to 2020. The model is designed with a Software Development Life Cycle (SDLC) approach. The results obtained are in the form of twenty shorelines per year as well as the amount of abrasion and accretion values from the interpretation. These results are visualized on an online-based map system that allows users to explore, synthesize, present and analyze the interpretation data. In conclusion, the Geovisualization system model is able to make serial data imagery presented dynamically to facilitate identification of shoreline changes.
Learning competence as an indicator of learning process achievement must be supported by appropriate learning media. There is little innovation in the development of geography learning media, and geography teachers' use of technology is still limited and ineffective. Making Augmented Reality-based learning media is one option for achieving the desired competencies. Geo-Augmented Reality technology is developed in stages, including the study of Prototype design theory, sketching out the Prototype, and continuing with the prototyping process. The Prototype is then used in conjunction with offline learning designs to provide a detailed model of field conditions for Geo-Augmented Reality media. Implementing this media-based learning is critical in order to meet the predetermined indicators of achievement of the geography learning process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
