“…In addition, Sutrisno et al stated that an increase in global temperature encourages an increase in rainfall in a certain region and time. Increased rainfall is a driving force for flood disasters [12]. Umar et al and Hoch et al stated that the area that is very dangerous when the intensity of rainfall is high is the area of the fluvial formation process (alluvial fans, natural embankments, river meanders).…”

Floods are the most common natural disasters in Indonesia and have enormous potential. This study aims to determine the flood hazard zone and regional arrangement in the Tarusan Watershed, South Pesisir Regency. To determine the flood hazard zone using the GIS approach. The indicators used to determine flood hazard are slope, rainfall, soil type, landform, geology, and land use. Determine the direction of regional arrangement with an Interpretative Structural Modeling (ISM) approach. The results showed that the high flood hazard zone in the Tarusan watershed is about 22% of the total area, the medium index is around 58%, and the low flood hazard index is 20%. The high - hazard zone of flood disasters in the study area is caused by high rainfall and topographic conditions of the Tarusan Watershed. The main priority in the management of flood - hazard areas in the Tarusan Watershed is to find economic alternatives to reduce forest destruction. Increasing the economic value of the community can lead to reduced community activities in carrying out land conversion, especially in forest areas.

“…Namun, dalam beberapa abad terakhir, pemanfaatan sumber daya alam telah berubah secara dramatis. Revolusi industri dan pertumbuhan populasi manusia yang cepat telah meningkatkan permintaan akan sumber daya alam secara eksponensial (Sutrisno et al, 2020). Peningkatan konsumsi sumber daya alam telah membawa dampak serius pada lingkungan (Putri dan Citra, 2018).…”

The research was carried out in Boroko Village, North Bolang Mongodow Regency with the aims of: (1) collecting data on natural resources on the Batu Pinagut coastline (2) Describing the potential for developing natural resources on the Batu Pinagut coastline (3) Analyzing policies on damage control. Determination of the sample using purposive sampling technique. Data was collected using observation, interview, documentation and document recording techniques. The results of the research show: (1) Batu Pinagut Beach has coastal resource potential that has been developed, namely biological resources and non-biological resources (2) management of coastal resources in Pemuteran Village includes tourism coral reef conservation in terms of tourism service training (3) Resource policy needs regulations are enforced, so that there is balance, preservation and continuity of resources. The rules do not apply to all areas, but to areas needed for the spawning and breeding of marine biota. To manage this area, it is necessary to have a conservation area that is equally understood and recognized by every stakeholder, stakeholders, fishermen, government, community and government. The rules and policies that are implemented involve stakeholders which become a culture that develops in society so that protection/conservation areas become a necessity and are implemented consciously by the community.

Water demand should be balance with water availability. The population of Bogor City was increased every year, so that water demand become increased. Currently, Government of Bogor City only utilizes the Cisadane river as a source for drinking water, but Bogor City has 2 rivers there are Cisadane river and Ciliwung river. So, Ciliwung river can be solution for this problem. Water discharge and rainfall influence water availability. Distribution log pearson type 3 used to predict the water discharge and rainfall and linier regression analyzed the relationship between water discharge (dependent variable) with rainfall as X1 and water level as X2 (independent variable). The result of distribution log pearson type 3 every return period 2, 5, 10, 25, dan 50 years is water discharge and rainfall were increased. Average increase of water discharge every return period is 1.6 m3/s and average increase of rainfall every return period is 251 mm. Partially, water discharge influenced by water level 97.7% and 2% by rainfall. But, = 0.000 < = 0.05. it is mean rainfall and water level cannot be ignored because it can influence water discharge with regression model = -3.01 + 0.000 X1 + 0.202 X2.
