“…In this case, the water flows towards the lower slope. Thus the index value will be greater on very flat slopes and vice versa the index value is smaller on steep slopes [18]. If an area accumulates water flow then the soil will become water saturated.…”

Fena Leisela sub-district is often hit by floods in the rainy season. Floods that often occur in the Siwalalat sub-district are caused by the overflowing of the Waegeren river. The research used DEMNAS data and analysis using the Topographic Wetness Index method. The results of the inundation potential analysis are divided into three classes, namely low potential class with an area of 92,196.09 or 63.04%, medium class of 45,769.48 ha or 31.29%, and a high potential class of 936.12 ha or 5.67%. Waelana-Lana village (3,291.78 ha), Wamana Baru (1,349.33 ha), and Waspait (936.12 ha) are villages that have the largest area in the high flood hazard class in Fena Leisela Sub-district. In the medium flood class, Raheriat village (8,243.39 ha) is the village that has the largest area presentation compared to other villages and for the low flood hazard class, Wamlana village (14,811.98 ha), Waemite village (12,305.48 ha) and Waelana-lana village (1,680.33 ha) are the villages that have the largest area compared to other villages in Fena Leisela Sub-district. The results of this study are expected to be a reference for the government and the community in handling future floods to minimize the impact that occurs.

“…Pada daerah sekitar pelabuhan merupakan daerah yang memiliki kerawanan banjir tinggi. Hal ini disebabkan karena kemiringan lereng yang landai, curah hujan yang sedang, penggunaan lahan yang terdiri dari; jasa dan pendidikan, dan yang terakhir adalah tekstur tanah yang sedang menurut skala wenworth, serta dipengaruhi oleh kecepatan drainasenya (Rakuasa, 2022).…”

Karimunjawa merupakan wilayah kepulaun yang terletak di selatan kabupaten jepara yang berseberangan dengan Kota Semarang. Namun, sebagai sebuah pulau yang berada di wilayah pesisir, Pulau Karimunjawa rentan terhadap bencana alam seperti banjir, badai, dan tsunami. Oleh karena itu, penting untuk melakukan analisis pemetaan risiko bencana di Pulau Karimunjawa guna meminimalisir kerugian yang ditimbulkan oleh bencana alam terutama bencana banjir. Penelitian ini menggunakan metode skoring dan matching untuk mengetahui daerah mana saja yang memiliki potensi banjir dengan parameter skoring berupa lereng, tekstur tanah, intensitas hujan, dan penggunaan lahan. Dari skoring dan matching didapat bahwa terdapat tiga wilayah yang berpotensi banjir. Wilayah pelabuhan memiliki kerawanan banjir tinggi akibat banjir rob, wilayah pemukiman memiliki kerawanan banjir sedang akibat banjir limpasan dari Bukit Joko Tuwo, dan wilayah Bukit Jowo Tuwo memiliki kerawanan banjir rendah karena wilayahnya yang tinggi.

“…Floods are a type of disaster that occurs due to the inability of the soil and drainage networks to absorb or accommodate runoff on the surface, thus creating large-scale inundations or flows that are detrimental and damaging [1][2][3]. Flood disasters can occur anywhere and at any time, depending on the situation and conditions that have the potential to trigger the disaster.…”

“…Based on the location of the surface runoff source, the types of flood disasters that occur are dispatch/flash floods and local/overflow floods. In contrast, regular and irregular floods are flood disasters based on mechanisms or processes [3,4]. Flood disasters occur almost all over the world, and one of them is Indonesia, with the number of incidents tending to increase in the last five years.…”

Flood is a disaster that occurs in almost regions of Indonesia, including DKI Jakarta province. From 2016 to 2020, there were more than 50 flood events in DKI Jakarta province. Several previous studies mentioned various factors that could cause flooding in DKI Jakarta province, including rainfall intensity, sea surface level, land surface level, and land use changes. This study aims to analyze and find out the main factors that cause floods in DKI Jakarta province. The data obtained from processing the interpretation of satellite imagery and literature review were then analyzed using a quantitative descriptive method with the Pearson correlation test to determine the coefficient value and the level of correlation/relationship between variables. The results showed that the rainfall intensity has a value of 0.968, the land use changes factor is 0.138, the land surface level factor is 0.095, and the sea surface level factor has a value of 0.051. Rainfall intensity has the highest value, with a strong correlation/relatedness to flood events. Land use changes, land surface level, and sea level have a shallow correlation/relationship to flood events. Thus, the rainfall intensity is the main factor causing flooding in DKI Jakarta province.
