Abstract

Sedimentation is one of the main factors affecting the hydraulic capacity and performance of urban rivers. This study aims to analyze flow capacity and the impact of sedimentation on a river’s ability to convey flow optimally. Flow capacity analysis was conducted using the Frijlink method with a rectangular channel cross-section approach, while sediment distribution and accumulation were analyzed through hydraulic modeling using HEC-RAS software. The analysis results show that the river’s flow capacity is 3,381 m3/s. An evaluation of bed sedimentation indicates that observation point 3 has the highest sedimentation rate, with a sediment discharge of 2.85 × 10-8 m3/s/m and a sedimentation volume of 5.78 × 10-4 m3/s. The HEC-RAS modeling results show that the river’s capacity is unable to accommodate the flow rate optimally under high rainfall conditions, thus potentially causing local flooding or waterlogging.

Abstract

Abstrak Kegiatan pengabdian masyarakat ini difokuskan pada penyediaan bantuan desain infrastruktur sanitasi tepat guna untuk menangani limbah domestik di Kelurahan Gandus, Kota Palembang. Urgensi perancangan ini didasari oleh kondisi geografis wilayah yang berada di kawasan bantaran sungai, di mana limbah domestik yang tidak terkelola berisiko tinggi mencemari badan air secara langsung dan merusak ekosistem perairan sungai. Perancangan Instalasi Pengolahan Air Limbah (IPAL) Komunal ini menjadi solusi strategis dalam meminimalisir pencemaran lingkungan pada pemukiman padat penduduk tersebut. Sistem ini dirancang untuk melayani kebutuhan sanitasi bagi 67 (KK) dengan kapasitas volume efektif reaktor sebesar 27.200 liter (27,2 m3 /IPAL) guna memastikan air buangan memenuhi baku mutu sebelum dialirkan. Desain teknis yang diterapkan mengadopsi sistem pengolahan biologis anaerobik yang mengintegrasikan empat kompartemen utama yaitu bak pengendapan dengan sistem Anaerobic Baffled Reactor (ABR) pada tahap awal, diikuti dengan dua tahap biofilter menggunakan media bioball dan media batu pecah untuk mengoptimalkan degradasi polutan organik. Struktur unit pengolahan ini memiliki dimensi total panjang 900 cm, lebar 200 cm, dan tinggi 200 cm. Berdasarkan pertimbangan kemudahan operasional dan efisiensi pemeliharaan bagi warga setempat, air hasil pengolahan akhir diarahkan untuk langsung dialirkan menuju sistem drainase lingkungan atau badan air terdekat. Diharapkan implementasi rancangan ini dapat memberikan kontribusi signifikan terhadap pelestarian ekosistem sungai serta peningkatan derajat kesehatan masyarakat di wilayah Kelurahan Gandus. Kata kunci: IPAL komunal; sistem anaerobik; sanitasi bantaran sungai; kelurahan gandus. Abstract This community service initiative focuses on providing design assistance for appropriate sanitation infrastructure to manage domestic wastewater in Gandus Village, Palembang City. The urgency of this design stems from the area’s geographical location along a riverbank, where unmanaged domestic wastewater poses a high risk of directly polluting water bodies and damaging the river’s aquatic ecosystem. The design of this Community Wastewater Treatment Plant (WWTP) serves as a strategic solution to minimize environmental pollution in this densely populated residential area. This system is designed to meet the sanitation needs of 67 households (HH) with an effective reactor volume capacity of 27,200 liters (27.2 m³ / WWTP) to ensure that effluent meets quality standards before discharge. The technical design employs an anaerobic biological treatment system integrating four main compartments: a sedimentation tank with an Anaerobic Baffled Reactor (ABR) in the initial stage, followed by two biofilter stages using bioball media and crushed stone media to optimize the degradation of organic pollutants. The treatment unit structure has total dimensions of 900 cm in length, 200 cm in width, and 200 cm in height. Considering operational ease and maintenance efficiency for local residents, the treated effluent is directed to be discharged directly into the local drainage system or the nearest water body. It is hoped that the implementation of this design will make a significant contribution to the preservation of the river ecosystem and the improvement of public health in the Gandus neighborhood. Keywords: community wastewater treatment plant; anaerobic system; riverbank sanitation; gandus subdistrict.

Abstract

Abstrak Permasalahan drainase pada kawasan permukiman perkotaan adalah genangan akibat kapasitas saluran yang tidak mampu menampung debit limpasan air hujan. Kondisi ini terjadi pada Kawasan Perumahan Bukit Sejahtera RW 04 Kelurahan Karang Jaya Kota Palembang yang mengalami permasalahan sedimentasi, penyumbatan saluran akibat sampah domestik, serta kerusakan konstruksi drainase. Tujuan PkM ini memberikan bantuan rekomendasi redesain saluran drainase sebagai upaya meningkatkan kinerja sistem drainase lingkungan dan mengurangi potensi genangan. Kegiatan dilaksanakan oleh 5 dosen dan 6 mahasiswa Universitas Indo Global Mandiri dengan melibatkan pihak Kelurahan Karang Jaya dan perwakilan masyarakat RW 04. Metode pelaksanaan kegiatan meliputi tahap persiapan, survei lapangan, pengumpulan data, analisis kondisi drainase menggunakan EPA SWMM, penyusunan rekomendasi desain, serta sosialisasi dan penyerahan hasil kegiatan. Berdasarkan hasil simulasi EPA SWMM, dilakukan optimasi pada 4 ruas saluran prioritas yang terdiri atas 2 saluran primer dan 2 saluran sekunder. Hasil simulasi setelah optimasi menunjukkan meningkatnya kapasitas aliran sehingga jaringan drainase mampu mengalirkan debit rencana dengan lebih aman. Kegiatan sosialisasi mendapatkan respons positif dari masyarakat yang ditunjukkan melalui antusiasme peserta dalam menyampaikan permasalahan drainase yang terjadi di lingkungan. Rekomendasi desain yang dihasilkan diharapkan dapat menjadi acuan dalam pengembangan sistem drainase di kawasan Perumahan Bukit Sejahtera. Kata kunci: drainase; perumahan; redesain saluran; EPA SWMM. Abstract Drainage issues in urban residential areas are caused by standing water due to insufficient capacity of the drainage system to handle the volume of rainwater runoff. This condition occurs in the Bukit Sejahtera Housing Estate in RW 04, Karang Jaya, Palembang, where there is sedimentation, blockage of the drainage system due to domestic waste, and damage to the drainage system's construction. The goal of this PkM is to provide recommendations for redesigning the drainage system to improve its performance and reduce the potential for flooding. The project was carried out by five faculty members and six students from the Indo Global Mandiri University, in collaboration with the Karang Jaya District Office and the RW 04 community representatives. The implementation method of the activity includes the preparation stage, field survey, data collection, analysis of the drainage conditions using EPA SWMM, design recommendations, and socialization and delivery of the activity results. Based on the EPA SWMM simulation results, optimization was performed on four priority channels, consisting of two primary and two secondary channels. The results of the simulation after optimization show an increase in flow capacity, so the drainage network can safely handle the planned flow rate. The socialization activity received positive feedback from the community, as evidenced by the participants' enthusiasm in sharing drainage issues in their environment. The design recommendations produced are expected to serve as a reference for the development of the drainage system in the Bukit Sejahtera housing complex. Keywords: drainage; housing; redesigning channels; EPA SWMM.

Abstract

One of the largest cities, because it is the center of social and economic activities, is Palembang City. The area of ​​Palembang City is around 400.61 km², consisting of 16 sub-districts and 107 villages. In this area, heavy rain has occurred which has caused flooding in this area, especially on Jalan Pipa Raja, Palembang City. One of the causes of flooding in Palembang is due to low land conditions and high tides of the Musi River. In the role of flood control, the lack of public awareness in maintaining the drainage system also worsens waterlogging. Flood control requires extensive and specific engineering knowledge. The structural method used in this study is the retention pond method. The retention pond on Jalan Pipa Jaya in Kemuning District has a capacity of around 328.8 m3/hour. Data for this study were obtained from literature studies, primary data, and secondary data. The results of the study that have been carried out indicate that in modeling using HEC-HMS, it is known that the Pipa Jaya retention pond can accommodate a peak inlet discharge of 161.3 m3/s, with a decrease to 29.7 m3/s.

Abstract

The Tampang Lake Irrigation Area, located in Muara Enim Regency, South Sumatra Province, is a wetland region that is highly susceptible to flooding due to high rainfall intensity and relatively flat topography. This study aims to analyze the design flood hydrograph of the Lingkis River using the HEC-HMS hydrologic modeling software. The novelty of this study lies in the integration of rainfall analysis, Intensity–Duration–Frequency (IDF) curve analysis, the Alternating Block Method (ABM), and HEC-HMS simulation for a wetland irrigation area that has received limited attention in previous studies, particularly within the Tampang Lake Irrigation Area. The research methodology involved simulating flood hydrographs using HEC-HMS, with the simulation results serving as the basis for estimating the design flood discharge. The analysis indicates that the highest rainfall intensity occurred at a 10-minute duration with a 10-year return period, reaching 126.80 millimeters per hour. The HEC-HMS simulation produced peak flood discharges of 176.7 cubic meters per second with a runoff volume of 40.05 millimeters for the 2-year return period, 234.7 cubic meters per second with a runoff volume of 52.88 millimeters for the 5-year return period, and 274.1 cubic meters per second with a runoff volume of 61.56 millimeters for the 10-year return period. The findings of this study are expected to contribute to the provision of reliable design flood discharge data to support the planning of wetland irrigation systems and flood mitigation efforts in the Tampang Lake Irrigation Area.
