In Indonesia, water resources management planning has done based on river area. But the problem is the calculation still based on population data with administrative boundary. This is caused by the lack of population data with watershed or river area boundary. Geographical Information System (GIS) is a tools to analyze, visualize and interpret data with spatial and geographic data. For this research, GIS is used to generate population data with watershed and river area boundary,then the result will used for domestic water demand calculation for Cisadane upstream watershed. For all district in Cisadane Upstream Watershed, the largest district in entire watershed are Cibungbulang, Leuwiliang and Nanggung. But the most dense population are Ciomas, Ciampea and Cibungbulang. The calculation using watershed boundary resulting significant difference from district boundary. With spatial data population using watershed boundary, domestic water demand calculation result can be more accurate than using all district population data.

Bintang Alam is housing area in Karawang regency which often occurs flood. Bintang Alam housing has a land area of 147,33 ha and located on the edge of the Citarum River downstream section. Therefore, it is necessary to have a good implementation and planning for the drainage system in Bintang Alam housing. The research aimed to find an effective way to prevent and solve floods in Bintang Alam. There are 2 scenarios that applied to the drainage planning at the Bintang Alam estate. Scenario 1, direct runoff from housing area is going directly to channel then the outlet point and for scenario 2, most of the flow entered to the soil through the infiltration wells then some of its flow into retention ponds. With the application of the two ecodrains, it is proven that they are able to reduce the planned flood discharge in the area with infiltration wells to reduce flood discharge by 25,96% and retention ponds to reduce flood discharge by 33,91%.

The hydrological and environmental cycles in a river area strongly affect rainfall intensity and seasonal patterns. To accurately assess water resource capacity, precise rainfall data from each observation station is crucial. However, unevenly distributed rain gauges often challenge researchers, as insufficient data can hinder their analysis. In these situations, satellite images can provide valuable additional information.Aims: The objective of this study was to analyze the accuracy of CHIRPS satellite rainfall data from observation stations in the Ciliwung watershed, especially in the DKI Jakarta Province area, over the last 30 years (1993–2022).Methodology and results: Statistical analysis such as multiple linear regression with the stepwise method is used to analyze CHIRPS rainfall against observed rainfall data according to the location of the rain station. The validation results in this study show that the average results of the two observation stations have a value of R2 = 0.91 and NSE = 0.9068.Conclusion, significance and impact study: CHIRPS data can be categorized as very good if used as an alternative to limited observational rainfall data, which can then be used in analyzing water availability in the Ciliwung watershed (Jakarta).

Freight transportation by rail is considered to be more time-efficient than road transportation. In response, the government has activated the freight rail line between Tawang Station and Tanjung Emas Port.Objectives: This study focuses on solving drainage system problems by designing a drainage channel.Methodology: This study uses hydrological and hydraulic calculations that are needed to get drainage design.Conclusion, Significance and Implication: The open space condition along the section of Stasiun Tawang – Pelabuhan Tanjung Emas from Km.0+275 to Km. 0+660 meets the standards ranging from 2.44 to 10.87 meters, while the standard used is 2.35 to 2.53 meters. Therefore, a drainage canal can be constructed. The results of the hydrological analysis show the planned flood discharge for 5-10 years. For 5 years, it is 0.906075 m³/sec, and for 10 years, it is 1.029242 m³/sec. The design for the new spillway includes trapezoidal and rectangular shapes. The trapezoidal design uses a cross-sectional width of 0.60 meters and a channel height of 0.70 meters, while the rectangular design uses a cross-sectional width of 0.80 meters and a channel height of 1.00 meters.
