This research aims to assess community coping capacity especially in implementing post-tsunami disaster mitigation and adaptation in the coastal environment of Sumberagung Village. Sumberagung Village is a vulnerable area exposed to the tsunami. The past tsunami in 1994 has caused many losses to the people at Pancer Beach and Pulau Merah Beach. More than 200 people were dead at Pancer Beach. Data collection techniques on this research could be divided into two; primary data and secondary data. Primary data is obtained by conducting field surveys and in-depth interviews with the local inhabitants. While secondary data is obtained through relevant government agencies such as the Regional Disaster Management Agency (BPBD), Village Monograph Data, and Statistics Agency Bureau (BPS). Data identification was carried out in a qualitative descriptive manner by adjusting the findings of the field with the study of existing theories. The results of the study indicate that in general the appeal for the threat of a tsunami disaster has already existed but has not been comprehensive. On the other hand, not all of the inhabitants have not taken many lessons learned from the 1994 tsunami. Adaptation in the form of shelter that is safe from the threat of a tsunami has not been seen by residents in Pancer Beach. This field condition shows that after the 25 years of the tsunami event, the local residents have not been fully able to implement a mitigation strategy, especially on emergency.

Pembelajaran abad 21 mengarahkan guru untuk mengintegrasikan penggunakan teknologi dalam pembelajaran. Pembelajaran sebagai kegiatan dimana terjadi proses belajar seseorang secara sadar untuk memperoleh ilmu pengetahuan, keterampilan maupun tujuan pembelajaran yang melibatkan kedua pihak yaitu guru dan siswa, salah satunya dapat difasilitasi dengan menggunakan bahan ajar digital. Bahan ajar digital memberikan kemudahan dan kelancaran dalam proses pembelajaran melalui belajar aktif dan mandiri. Selain itu, manfaat bahan ajar dapat membantu memberikan informasi terkait materi, meningkatkan siswa untuk berpikir atau memahami, serta memberikan pengalaman langsung (konkret) agar berkembang secara berkelanjutan. Penelitian ini bertujuan untuk menghasilkan bahan ajar yang efisen dan efektif dalam menunjang proses pembelajaran Geografi secara optimal. Penelitian ini termasuk ke dalam penelitian dan pengembangan. Model penelitian dan pengembangan ini menggunakan model ADDIE. Berdasarkan prosedur pengembangan dilakukan uji validitas produk, baik pada validator ahli materi dan desain pada bahan ajar dinyatakan valid. Kemudian, berdasarkan hasil uji coba lapangan baik respon guru dan siswa mengenai bahan ajar digital memberikan respon cukup baik dengan klasifikasi bahan ajar sangat layak.
