Abstract

Sedimentation that occurred in the Lematang River in Lahat Regency was caused by river bank erosion, construction activities, and household waste brought by the flow discharge. The flow of the Lematang river will certainly affect the amount of sedimentation that will occur in the Lematang river.Based on the test results of the analysis of sediment sample filters, the results obtained d50 = 0.425 mm, and the results of research on the river cross-section with the aim to calculate the volume of base sediment sediment / bed load that occurs by flowing Lematang river flow obtained H = 0.41 m, B = 0 , 41 m, V = 2,650 m / sec.Based on the results of the analysis of the influence of flow discharge on sedimentation in the Lematang River, Lahat Regency, it is known that the type of bed load sediment in the Lematang River is poorly graded sand with large sediment transport carried by the flow discharge in the study segment of 0.022 (m3 / sec) with the duboy's method and 0.0000004 (kg / sec / m) with the shield's method, so the sediment volume for the next one year is 693,792 (m3 / sec) m for the duboy's method and 126,144 (kg / sec / m) for the shield's method .

Abstract

Di Sub DAS Lambidaro, tepatnya di Jalan Kolonel Sulaiman Amin masalah banjir terus terjadi terutama saat hujan. Terjadinya banjir di sekitar saluran di sepanjang drainase jalan Kolonel Sulaiman Amin disebabkan oleh beberapa faktor, salah satunya adalah kapasitas tampung yang tidak mampu mengendalikan debit banjir secara maksimal sehingga air tidak mampu melimpas ke saluran dan akhirnya menyebabkannya banjir di daerah sekitarnya. Penelitian ini dilakukan untuk mengetahui apakah kapasitas drainase masih mampu mengalirkan air limpasan permukaan atau tidak dan untuk menentukan berapa dimensi yang pas untuk mengatasi banjir yang terjadi pada Jalan Kolonel Sulaiman Amin.

Abstract

The large amount of rubbish in the river flow in the Bendung sub-basin has prompted the government to create an innovation to deal with this problem. This innovation is the installation of trash booms at critical points. However, the installation of the trash boom is thought to slow down the flow downstream, causing a delay in the time for the river water level to recede. After conducting a comparative analysis of river flow velocity using a current meter, it was found that there was a 34% decrease in flow velocity in the downstream part of the river, where the first flow velocity was 0.29993 m/s, decreasing by 0.10099 m/s to become 0.19894 m/s downstream after the trash boom installation point.

Abstract

Inspector Yazid Road is one of the important routes often used by vehicles in Lahat District, Lahat Regency. Especially in the lower market area of Lahat, various problems often arise in traffic conditions. Activities in the market have a major impact on the increasing number of daily activities and are one of the main factors causing high traffic volumes. Various side obstacles also worsen the performance of the road section. Referring to the problems that have been mentioned, the author tried to conduct a study to assess and analyze the performance of the Inspector Yazid road section using the 2023 Indonesian Road Capacity Guidelines (PKJI). The data collected included road geometry, vehicle flow, side obstacles, and population in Lahat Regency. The data was then analyzed based on the 2023 Indonesian Road Capacity Guidelines. The results of the study showed that peak times occurred on Monday to Friday between 16.00 and 17.00 WIB, with a vehicle volume reaching 1537 smp/hour, side obstacles 1122 kej/hour, and a capacity of 1837 smp/hour. The free flow speed was recorded at 49.92 km/h, travel speed at 13.64 km/h, and the degree of saturation at 0.84, which indicates that traffic on Jalan Inspector Yazid is in an unstable condition and is almost approaching the maximum capacity limit.

Abstract

Floods have a damaging impact on at-risk areas such as areas with relatively high land cover, especially after heavy rains. Land cover is the influence of land use. In land use, the runoff coefficient (C) is a factor that greatly affects the amount of water runoff that occurs during and after rain. The runoff coefficient (C) describes how large the proportion of rainwater that will flow as surface runoff compared to the water that seeps into the soil, so, the closer the coefficient value is closer to the value of 1, the more an area is unable to absorb water, as well as if the runoff coefficient (C) is closer to 0, the more an area can absorb water well. The runoff coefficient (C) has a high correlation with land use. In this study, the variation of runoff coefficient (C) will be simulated on rainfall and area using rational equations and then the results are simulated using HEC-RAS. The variation in runoff coefficient (C) was simulated with the criteria conditions of cultivated land, clay & silt loam soils (C= 0.4) and regional conditions when only able to overflow water or unable to absorb (C= 1). The results were found that the runoff coefficient (C) affects the area and depth of flooding in the study area. At C = 0.4 the maximum flood depth is 2.99 meters in the upstream part of the river and 1.65 meters downstream, while when C = 1, the maximum flood depth is 2.03 meters in the upstream part and 1.1 meters in the downstream part. In this case, it is important to prepare rainwater reservoirs in areas with relatively high land cover or runoff coefficient (C).
