Rainwater harvesting system (RWH) implementation may be a solution to maximize the water availability and reduce the runoff volume in Palembang City. For successful implementation, it is necessary to identify potential areas for RWH implementation. This study aims to identify areas in Palembang that are potential for implementing the RWH system. An analysis of parameters that affect the classification also conducted. This study used a geographic information system (GIS) approach using rainfall, slope, land use, and soil type parameters which are structured in a hierarchy using the analytical hierarchy process (AHP). Based on the weighted overlay method, it can be concluded that a very potential area for RWH implementation dominated with a wet area, flat slope, dense residential area and the type of soil which is not susceptible to infiltration. Whereas the medium and non-potential areas are dominated by steep and very steep slopes as well as unoccupied land use. Areas of high potential and potential reach 18.17% and 66.14% respectively. While the medium and not the potential is 13.66% and 2.03%. Areas of great potential are in the Buah, Kidul, Sekanak, Sriguna, Bendung, and Selinca Sub Watershed. Non-potential areas are only available in small area in DAS Gandus, Gasing, and Lambidaro Sub Watershed.

Brimob retention basin is located within the Sekanak Sub-watershed system, which is a flood-prone point. Administratively, the Brimob retention basin area is a part of the Sub-district of Ilir Barat I. The research method used is computer modeling. The steps taken are data collection, hydrological analysis, cross-sectional analysis, hydrological and hydraulic modeling using pumps. The Brimob retention basin can accommodate a volume of water up to 115,103.73 m3, up to an elevation of the embankment of + 4.30 m. The magnitude of designed rainfall is R2 = 118.78 mm, R5 = 144.78 mm, R10 = 161.99 mm and R25 = 183.73 mm. The peak discharge of each return period is Q2 = 6.30 m3 / s, Q5 = 7.67 m3/s, Q10 = 8.59 m3/s and Q25 = 9.74 m3/s. To assess the effectiveness of pump operation, 2 (two) pumping capacities are simulated, namely: 250 l / sec and 500 l / sec, each used 2 (two) pump units. The simulation used a pump with a capacity of 500 l / sec, and the amount of discharge (inflow) for each return period is as input. The conclusion is that the use of a pump with a capacity of 500 l / sec can overcome excess water volume and avoid runoff and be effective in dealing with the excess water in the Brimob retention basin.

The tides, which affect the water level of the Musi River causes some problems to occur in Palembang City. One of the main problems related to the tides of the Musi River, especially the low tide, is the failure of the raw water intake building of Regional Drinking Water Company (PDAM) Tirta Musi, Palembang City to operate. At a certain time the river water level recedes, the minimum water level entering the intake pump room is lower than the safe level for the pump to run. In this study, an analysis of the tides of the Musi River was carried out using the Least Square method to evaluate the design of the raw water intake building for the Gandus system to disclose whether it meets the minimum elevation requirements for pump operation. The field observations of the tides were carried out for 15 days for every 1 hour to obtain the primary data for this study using the Hobo Water Meter. The results of this study indicate that the type of the tides in the location of the study is a mixed tidal type with a Formzahl Value of 2.01. 4. Against the design plan of the gandus system of raw water intake, there is a chance that the elevation of the river water level is at 0.5 m from the end of the pump suction pipe, in which the pump cannot function.
