Land use change due to housing construction can indirectly damage the water catchment area. This resulted in a decrease in the area of rainwater absorption that caused rain water collected on existing drainage channels. This study aims to analyse the number and dimensions of infiltration wells in reducing the volume of inundation and determine the value of effectiveness reduction of runoff. The infiltration wells was used to collect rainwater and absorb it into the soil. Based on the calculation in Babakan Village area of 2.42 ha, with runoff coefficient of 0.4 for village character, and design rainfall of 97.36 mm/day, the estimated flood volume based on SNI 03-2453-2002 was 805790.30 liter or 805.79 m3. Based on the calculation, Babakan Village needed 115 infiltration wells and 76 trenches. With the infiltration wells and trenches, the total flood volume can be reduced 620.62 m3 or 77.02% of the total runoff.Keywords: design rainfall, infiltration wells, runoff, trenches

Fresh water is basic needs for human being. The safest for human consumed is groundwater. Groundwater demand will always increase in accordance with the development of an area. The purposes of this research were to identify the depth of aquifer, to know the effectivity of IPI2Win software, and to analyze potential of groundwater reserves in Dramaga District. Groundwater exploration was conducted using geoelectrical methods. This research had done in Dramaga District since January until June 2018. Data were processed using IPI2Win. Based on 9 points measurement at Dramaga District, the soil layer contained a lot of water. IPI2Win was effective to identify aquifers. Based on GL 1, GL 2, GL 5, and GL 6 measurement points which close to the residence area, the aquifer depth was identified less than 6 m with an error value of <15%. Potential of groundwater reserves for unconfined aquifers was 1048.45 m3/day or 12.13 l/s..Keywords: aquifer, geoelectrical method, groundwater, IPI2Win, resistivity

The intensity and duration of rainfall will affect the amount of runoff. A proper drainage design is needed so that runoff from maximum rainfall would not cause a problem such as excess water or flood. The purpose of this research were to analyze the runoff volume in Tasmania Regency, Bogor and get drainage network design in accordance with the runoff that occured. Analysis was carried out using SWMM 5.1 software with designed rainfall was calculated using the Log-Person III method of 147.2 mm. Peak discharge runoff from simulation results were 0.01 - 0.08 m3/s. Based on the simulation there were 20 channels overflowed during maximum runoff and 6 channels were high potentially overflowed so that repairs were also needed. The factors that influenced were the amount of runoff, channels capacity were lower than runoff volume, and the low infiltration value of subcatchment so that only a little water could be infiltrated and the rest of rainfall became runoff.Keywords: drainage channel, rainfall, runoff, SWMM 5.1

Groundwater needs will increase in accordance to area development. Groundwater has a limited quantity because it depends on the geometry and distribution of aquifer. The purpose of this study were to identify soil lithology and aquifer thickness, to determine soil hydraulic conductivity values and to predict potential groundwater reserves in Dramaga District . The processed data were data geoelectric with Schlumberger configuration, hydrogeological maps, and geological maps of Bogor. Aquifer thickness were obtained from the average yield of the aquifer thickness at the research location. Thickness of unconfined aquifer was 14,69 m and 17,77 m for confined aquifer. Aquifer had lithological layers of andesite, tuffaceous, sandstone, clay, and sand. The value of hydraulic conductivity was 2,5 m / day for unconfined aquifer and 2,04 m / day for confined aquifer. Using the Darcy equation groundwater reserves were estimated 241,29 m3 / day or 2,79 l / s for unconfined aquifers and 1291,19 m3 / day or 14,94 l / s for confined aquifers.Key words: aquifer, Darcy equation, geoelectric, groundwater reserves

Abstract : Increasing of population in a region is directly proportional to its development. Large number of populations resulted in the wider construction of residential areas. Construction of residential areas requires a clean water supply to fulfill households water demand. The purpose of this research were to analyze the domestic water demand and water availability in Bogor City, and to analyze the suitability between the domestic water supply and demand in Bogor City. The research was done from February to May 2018. This research needed data of population, hydrogeological map and annual river discharge. The correlation between population to domestic water demand using regression method was showed with equation Y = 19549X + 801520. In 20 years ahead domestic water demand will 80,328,688.57 m3 and total water demand will 125,312,754.2 m3, while total surface water availability will 174,078,720 m3/year. Domestic water availability in Bogor would decrease and would make clean water shortage after 2049 when population reached 1,720,323 persons. Keyword : domestic, surface water, water demand, water supply.

Land use change have an impact on infiltration capacity. There is often an annual flood on Kadumanggu District. When the rainfall is high so the river will be overflow. The outlet of Cikeas sub-basin was located on Kadumanggu District. This research aimed to determine the maximum discharge of the Cikeas River and analyze the relation between land use change and discharge of Cikeas River. The research was conducted by delineating the water catchment area, analyzing rainfall, making a land use map and modeling with HEC-HMS. Based on the modeling results, the maximum discharge of the Cikeas River in 2000 was 74.3 m3/s, in 2009 was 84.9 m3/s, and in 2018 was 91.7 m3/s. The catchment area with an extensive use as residential had a higher river discharge compared to the area with a large green area. It meaned that, land use changes greatly affected the river discharge.

Perubahan tata guna lahan menghasilkan pengurangan kapasitas absorpsi tanah dan peningkatan curah hujan yang dapat menyebabkan potensi banjir. Oleh sebab itu, perlu adanya usaha untuk mencegah hal tersebut. Desa Babakan yang merupakan penyangga kampus IPB khususnya RT 02 didominasi wilayah pemukiman yang memiliki potensi bencana. Penelitian dilakukan pada area pemukiman untuk menentukan sistem infiltrasi dari curah hujan untuk mengurangi resiko kebanjiran. Penelitian diawali dengan observasi lapang, analisis hujan dan pendugaan desain hidraulik dari bangunan infiltrasi air. Kemudian dilanjutkan dengan penentuan volume banjir, kapasitas infiltrasi dan efektifitas infiltrasi. Hasil penelitian menunjukkan bahwa debit banjir sekitar 1477.81 m3. Untuk mengatasi masalah banjir, sumur resapan dapat dibangun pada beberapa rumah dan bangunan sepanjang saluran drainase. Sistem infiltrasi yang dikembangkan dapat mengurangi 58.24% debit banjir.

Air tanah dalam adalh air yang terdapat pada suatu lapisan tertentu yang berada di dalam tanah baik sebagai ruang antar butiran batuan ataupun pada rekahan batuan. Jadi ruang antar butir, rongga batuan serta rekahan pada batuan. Air tanah dalam ini dapat bergerak secara lateral maupun vertikal yang dipengaruhi oleh keadaan morfologi, hidrologi, dan keadaan geologi setempat. Pengaruh faktor geologi antara lain adalah bentuk dan penyebaran besar butir, perbedaan dan penyebaran lapisan batuan dan struktur geologi. Untuk menentukan potensi air tanah melalui parameter-parameter akuifer di daerah penelitian dapat didekati dengan menggunakan analisis numerik dengan metode beda hingga (finite difference method).

Abstract The purpose of the geoelectricity resistivity survey in DKI Jakarta, i.e. in Taman Duta Cimanggis Resident and the Ministry of Environment Office is to find out the distribution of penetration zone beneath the surface. The geoelectricity method is intended to find out the depth and spread formation of the lower layer surface of the acquired resistivity value based prediction. Based on that resistivity distribution, geological subsurface conditions can then be interpreted. Hydrogeological condition in the research site was included to the aquifer system with wide range of groundwater spreads. Rocks which are expected to be aquifer in both site are sandy clay and sand. From the geoelectricity estimation observation results, the aquifer layer can be found out, i.e. in Taman Duta CImanggis Resident was in depth of 20-60 m below the ground surface with the lithological form of sand. While in the Ministry of Environment Office By Pass were in depth of 10-20 m (aquifer I layer with the lithological form of sandy clay) and 30-35 (aquifer II layer with the lithological form of sand).
