Floods during the rainy season has become routine events in several cities in Indonesia. Various reasons to trigger the occurrence of flooding, among other drainage network system capacity is decreased, increasing water flow, or a combination of both. The capacity of the drainage channel has been calculated based on the design criteria to accommodate the flow of water occurs so that the area is not experiencing inundation or flooding. The reduced system capacity due to, among others, many precipitates, physical damage or their network systems and illegal buildings on the system network. While the cause of the discharge increases, among others, high rainfall out of habit, changes in landuse, environmental damage to the basin in a region. Cases like mentioned above also occur in Sekanak Sub-basin, so it is necessary to study the drainage network performance evaluation system based on the concept of sustainable drainage based on community participation. Good and bad, high and low of the drainage network system performance is largely determined by community participation in management, especially with the lack or absence of funds from Palembang city government for the management of drainage network system. Drainage system performance can be evaluated from the technical aspects as well as non-technical. One technical aspect is the frequency analysis to look at the picture unit hydrograph. Analytical results from this study may be that the maximum flow of 25 m3 /sec at peak hours at the time of 4.8 hours and then slowly starting to go down at a time to 24 hours. The others aspect is Social construction problems can be solved by Public Participation approach, with the Government acting on the principle of fair, development activities carried out with transparency and attention to the needs of the community.Social problems occurring both at the pre-construction stage (land acquisition and resettlement), construction (procurement and mobilization of labor, mobilization of heavy equipment and construction materials and equipment operations) and post-construction can be anticipated by social engineering forming between Other identification of community character and institutions, socialization, public consultation, community gathering and community

Sediment-related disasters are terrible disasters that can catastrophically impact facilities. People must keep in mind to make sediment-related disaster information that can be predicted from rainfall and response of drainage area by using snakelike. This research produces important indices on precipitation related to debris. It shows the current status of the stage of the response of drainage area against rainfall by using a couple of short- and long-term indices. It shows the water storage volume in the soil layer with the calculation of soil water index (SWI) by using X-band MP (Multi-Parameter) rainfall radar data that has been installed at the top of Merapi Mountain (Merapi Museum). It was confirmed that from June 2018 – June 2019, with 80.28 mm SWI, maximum values do not exceed the standard reference value of SWI (120 – 160 mm) set from JMA. It means that 80.28 mm of SWI value has not yet become the maximum limit of SWI value for lahar occurrence in the Boyong drainage area (BO-D5). The maximum limit of SWI value can be generated if sediment disaster occurrences are available.

The drainage network system should be designed to accommodate normal flow rates, especially during the rainy season. This means that the capacity of the drainage channel has been calculated to accommodate the water discharge that occurs so that the area in question does not experience puddles or the channel can to be function properly. For this reason, research is needed to analyze the ability of the ex-coal mine drainage channel in PIT-3 West Banko Tanjung Enim. The research was carried out with the help of the HEC-RAS software program to see the changes in the water level in the drainage channel where the water was overflowing from the channel body. The results showed that all the section profiles of the drainage channel (P1) till (P10) were still in the safe condition or the channel was still stable (stable channel).

This research aims to examine the problem of erosion and sedimentation in canals in swampy areas in South Sumatra, namely the P8-13S scheme of the canal (SPD) Telang I, Banyuasin regency with the influence of flap gate. The research method used is to perform simulations in the laboratory using a scale model and related parameters, such as velocity (v), depth of erosion (de), sedimentation (ds), water density (ρw), gravitation (g), time (t) and distance (x). Dimensional analysis to determine the related parameters that produce a dimensionless parameter relationship model is carried out using the Langhaar method. The result of the study was that the maximum relative erosion (de/t)max occurred at the canals estuary near the flap gate, which was 0.255 during simulation times of 5 minutes. While the maximum relative sedimentation (dd/t)max also occurred at the estuary of the secondary canals (SPD) of 0.05 for 5 minutes. So, the sediment transport process in the secondary canal (SPD) is generally influenced by flow velocity and the presence of a flap gate in the canal to regulate sediment transport.

This research was conducted to obtain the right discharge plan in the irrigation area with a study of the amount of discharge that can be used upstream of the weir so that the water supply at the intake does not lack water. The Deras II Irrigation Area covering an area of 928 hectares, has 2 weirs as a source of irrigation water, namely the Moyan weir and Aur Weir. The upstream part of the Moyan weir is a sleeping area in the form of a swamp which farmers use to become a paddy field whose source of water comes from the swift river (upstream Moyan weir). With this water uptake, the impact on the flow of water entering the Moyan intake will be reduced, so it needs to be done with the numerical method approach of the HEC-RAS program. The results of this study are graphically depicted at each review station in the channel and the existing discharge obtained from the measurement of the speed with the current meter and water level from each cross-section along the irrigation channel. The simulation results are obtained with the condition of the river crossing, which is not filled, and the discharge is 0.024 m3/sec. The water level at the downstream cross-section is filled as high as 75 cm with a flow velocity of 0.783 m/sec, and the water level downstream of the irrigation channel is as high as 40 cm.

Musi River is the main river with a river length of more than 750 km and the average width of 540 m which is still affected by the tides of seawater from the thirteen existing river basin systems. Aur River is one of a tributary of the Musi River located in the Seberang Hulu area of Palembang city. Aur River needs to do research related to the rise in water level in the river body if extreme rainfall occurs that will cause inundation in the upstream area of the river. The study was conducted with a hydraulic model approach that is using a physical model of the channel with a scale model and data from existing prototypes and with the existing conditions and the running time of the model carried out for 1.50 hours with a certain period of time data collection is carried out both erosion and sedimentation data and later obtained patterns and the total amount of bed load at the estuary of river. The results of river erosion and sedimentation patterns later. The result of the research was sediment transport patterns with three times period are 30 minutes, 60 minutes and 90 minutes so that the formed of erosion and sedimentation pattern with the total bed load be range 0.66 cubic meter per day from formula, 6.34 cubic meter per day from Einstein’s & Lane and 7.48 cubic meter per day from MPM formula.

Flood is a common problem that occurs in parts of Indonesia. The Musi River and nineteen drainage systems in the city of Palembang that serve different cathment area units contribute to flood disasters each year. The effect of maximum discharge on the level of flood vulnerability is the continuation factor of land use results and (1) rainfall in addition to (2) tides that usually occur periodically on the Musi river. At high water velocities, it is fast and the amount of water is small, resulting in a high flow of water so that the flow is very heavy and has a destructive impact. The old paradigm for the construction of drainage channels or subdas was to channel water runoff to the nearest canal / water body so that it canreach the downstream faster. This paradigm is no longer suitable with current conditions where the flow of flowing water must be held longer by being infiltrated into the ground through water catchment areas such as infiltration wells, retention ponds, reservoirs and so on so that water does not immediately reach the downstream to maintain water supplies. The drainage system of Palembang City follows the natural drainage system pattern, because the drainage system is the main drain of the existing drainage zone, while the distribution of the drainage loading area is adjusted to the direction of the existing drainage flow (ESP-USAID, 2009). Drainage or Musi subdas in several areas in Palembang City which are water catchment areas that have changed their function into residential areas and with untreated drainage systems, narrowing of channels, silting and accumulation of garbage in drainage and puddles due to the capacity of primary drainage being exceeded so that at some time lately there has been frequent inundation and flooding during periodic rains and tides

Upaya peningkatan perekonomian masyarakat merupakan salah satu tujuan dari perkembangan dan pertumbuhan industri khususnya dibidang perkebunan. Karet sebagai salah satu komoditi utama mempunyai peranan penting dalam peningkatan perekonomian masyarakat di suatu daerah. Akan tetapi hal tersebut juga mempunyai dampak negatif seperti pencemaran dan kerusakan lingkungan apabila tidak di rencanakan dengan baik. Limbah karet yang tercipta sebagai sisa dari pengolahan karet mentah perlu adanya penanganan yang baik agar tidak merugikan dan perlu dimanfaatkan semaksimal mungkin. Pembuatan conblock pada dasarnya berupa campuran semen, pasir dan air, namun dalam hal pemanfaatan bahan tambahan yang tersedia seperti tatal karet sebagai hasil limbah, conblock ini dapat dimanfaatkan berupa beton non struktur yang terdiri atas campuran tatal karet, cacah plastik, pasir, dan semen. Pembagian persentase untuk bahan tersebut yaitu 5% untuk tatal karet yang sudah dikeringkan dan pasir sebesar 1%, 2,5% dan 5% sebagai perbandingan berat semen. Conblock yang dihasilkan terbukti dapat bermanfaat bagi masyarakat Muara Enim baik dalam segi ekonomi, produksi dan keindahan. Conblock tersebut dapat digunakan menjadi pembuatan lahan parkir, jalan setapak maupun dijual.
