Abstract. Wotgali Village is a slum area. The aim of the current research is to find out the performance of slum base infrastructure using Lakip (Government Agency Accountability Report) of KOTAKU (City without Slums) Program. The first step was performed by identifying the initial settlement (base line), then some treatments on the facilities and infrastructure (finish line), performance evaluation stages of the preparation, planning, implementation, and sustainability stages. The research used qualitative and quantitative approach. Qualitative measurement began with a numerical assessment of the results on the level of regional slum. In addition, quantitative data used the Lakip simulation using results of the KOTAKU program stage performance. Results of the initial condition reach value of 32%. It is categorized as slight slums with an average sectoral slum of 36.68%. Basic infrastructure development which has final technical reached 24% and is included in slight slum with an average sectoral of 27.50%. The performance of LAKIP Kotaku was in preparation phase 90.46% (very good performance), planning stage was 89.93% (very good performance), implementation stage was 90.25% (very good performance), sustainability stage was 85.21% (better performance). Thus, the achievement of KOTAKU program is 85.19% with a range of value of 80-90. The value is included as better performance result. Results of the analysis can be concluded that level of slum can be reduced to 19% (not slum) by creating some improvements to basic facilities and infrastructure. In the following year, involving Lakip Performance, the planning stage can be enhanced through community participation and active involvement.

Abstract. Darma Reservoir functions as a reservoir for irrigation, fisheries, and recreational and sports facilities. Currently, it only functions for irrigation and fish farming by floating net ponds. The development of floating net frameworks was so rapid that it conflicted with reservoir management. This study aims to determine the density of the floating net framework of the sedimentation conditions of the Darma Reservoir and to determine the development of the sedimentation rate of the Darma Reservoir in relation to the service life of the reservoir characterized by reduced dead storage. The first step was carried out by surveying the presence of the number of floating net cages, the distribution of the feed, the percentage of feed demand, the carrying capacity of the reservoir, then a topographic survey of the depth of the Darma reservoir to determine the capacity, rate and volume of sediment deposits. This study used quantitative approach, it began with distributing questionnaire forms and measuring the depth of the reservoir. The current condition of floating net cages is 4916 occupying 5.819% of the inundation area of 312.15 ha with an elevation of 712.50 m, while floating net cages are allowed according to the carrying capacity of Darma Reservoir waters amounting to 1,021. tons / harvest while the spawning pond is 3.483 tons/harvest. The volume of normal active storage for elevation 712.50 in 2020 is 28.086 million m3, while the volume of sediment deposits is 9.262 million m3 32.98%, the average sediment rate in the reservoir from 1988 to 2020 is 0.2894 million m3/year, while the sediment rate in catchment area Dam Dharma with an area of 23.5 km2 of 71.873 mm/year. Sedimentation in the Darma Reservoir has exceeded the limit of the base elevation of the reservoir, the elevation of the dead reservoir and the lowest elevation, but the reservoir is still functional. The planning life of the darma reservoir is up to 50 years, the suitability of the initial planning of operations in 1970 with operations until 2020.

The rain that fell in the city of Cirebon, especially the drainage on Jalan Pemuda, could not accommodate and drain the water so that it could create puddles on the roads and surrounding areas. Hourly rain intensity, planned flow rate and channel cross-sectional dimensions are the first steps for flood prevention. Hydrological analysis is used to calculate the discharge capacity of the drainage plan. The results were then analyzed the dimensions of the channel, the drainage ability to accommodate the falling rainwater where Qs is bigger than Qp. the channel discharge has not been able to accommodate the Q plan in the channel so that there will be a runoff of 17.759%. So to anticipate runoff, it is necessary to have a channel improvement plan of 33.477%. In addition to channel improvement solutions, arrange and define the boundaries of water storage areas by measuring and mapping boundaries and issuing regulations that prohibit or limit the construction of buildings that can reduce the ability of areas to store and absorb rainwater by referring to the basic building coefficient (KDB) permitted as stated in the RT/RW.

ABSTRACTSoil types have different infiltration rates and vary depending on the characteristics of the soil, how the infiltration relationship occurs with dry water content and saturated water content, infiltration relationship with the soil after being compacted and before compacted and how the infiltration rate of the two types of relationship and how infiltration water that happened. Soil tests are carried out in the laboratory, soil water content before and after the soil has been solidified, changes in the time of infiltration capacity with the Horton equation, rain hydrograph for overall infiltration analysis, including cumulative infiltration and runoff rates.Soils experience porosity filling not as great as in normal soil conditions, normal soil conditions changes in water content reaches 5.22 mm/hour while in soil conditions that experience changes in water content compaction at 30 minutes by 0.14 mm/hour and experiences a constant rate in the 40th minute at a rate of 0.20 mm/hour, so there is a difference in water content of 5.08 mm/hour between normal soil and soil after solidification, due to compacting it causes runoff of 8.92 mm/hour, normal soil with runoff of 3.78 mm/hour.Keyword : Infiltration, soil physical properties, runoff.

The Kalibaru Port of Tanjung Priok, North Jakarta, is one of the ports that is used for shipping and loading and unloading activities. Bathymetry information is needed to support one of the activities in the port, namely in terms of shipping. The purpose of this research is to map the bathymetry in the harbor pool area and to find out the areas that need to be dredged in the Kalibaru Tanjong Priok harbor pond. This research was conducted on May 24, 2022 in the pond area of Tanjung Priok Harbor, North Jakarta. This research was conducted using a single beam echosounder using a Garmin GPSmap 420s tool to determine the depth of the harbor pool. Data processing using Ms. excel, Auto CAD land desktop, surfer to generate depth contours and calculate dredge volume. The volume calculation uses the average end area method. The calculation result of dredging volume is the sum of the cross-sectional area multiplied by the section distance. The results showed that the depth of the Tangjung Priok harbor waters ranged from 3 to 17 meters and the dredged volume reached 165,319 m3.
