Abstract. Gedongtataan is the capital city of Pesawaran

Banjir terjadi hampir setiap tahun di Gedongtataan dengan tinggi genangan dapat mencapai 1,5 meter dan menggenangi beberapa desa di Gedongtataan. Banjir tersebut menimbulkan dampak negatif seperti masalah kesehatan, kemacetan lalu lintas, dan kerusakan material. Banjir yang terjadi disebabkan oleh curah hujan yang tinggi. Penelitian ini bertujuan untuk menganalisa curah hujan sebagai faktor penyebab banjir di Gedongtataan. Metode yang digunakan dalam penelitian ini adalah analisa pola curah hujan dan frekuensi curah hujan maksimum dengan metode Gumbel. Hasil menunjukkan bahwa curah hujan tinggi di bulan Januari, Februari, dan Desember. Curah hujan harian maksimum di Gedongtataan sebesar 118 mm/hari dan dari metode Gumbel diperoleh curah hujan harian maksimum sebesar 155 mm/hari dengan periode ulang 100 tahun. Curah hujan yang tinggi dan didukung ketidakmampuan drainase dan pengendali banjir lainnya dalam mengalirkan air limpasan hujan menjadi penyebab banjir di Gedongtataan.

The COVID-19 pandemic has affected the education system in Indonesia, one of which is the implementation of learning from home policies. To assist the learning process, corrosion e-learning based on flex discovery learning has been developed for senior high school. This research is a research and development with 4D model. E-learning has been validated by three validators and tested for practicality by 10 students of SMA Negeri 2 Pasaman, West Sumatra, Indonesia. Data were analyzed by Aiken V and the percentage of students' understanding, using instruments in the form of validity and practicality questionnaires. the average value of V content and construct validity test results was 0.86 and 0.88 and for practicality the average value was 0.83. These data prove that the developed e-learning is valid and practical so that it can be used in the learning process.
