Abstract

Urbanization is one of the factors that cause an increase in the number of residents in urban areas. The increase of population has an impact on increasing settlements which result in changes in land use. One of the residential areas in Medan City is Perumahan Taman Alamanda Indah which is located in Tanjung Selamat, Medan Tuntungan District. Around 60.7% of the area of Perumahan Taman Alamanda Indah is a closed area in the form of houses and roads which causes high surface runoff when heavy rain occurs. The study aims to plan infiltration wells that can function to reduce flood discharge in Perumahan Taman Alamanda Indah area. The planned infiltration well is a communal well that is divided into several zones. It is planned that 50% of the maximum discharge of rain that falls on the roof of the house is absorbed into the infiltration well. From the results of the study, the required number of infiltration wells is 430 units with a diameter of 1 m and a depth of 2 m which is divided into 13 zones. The construction of this infiltration well can reduce the peak discharge in housing by 36.71%.Key words: land use, infiltration wells, flood

Abstract

Hydrological analysis is conducted to determine the rainfall discharge that can be accommodated by the river with various specific return periods and hydraulic analysis to examine the water level that impacts the toll bridge that passes through the Sei Batang Serangan river. Therefore, this research was conducted to calculate the design flood discharge for the return period of 2, 5, 10, 25, and 50 years; and the water level elevation of Sei Batang Serangan toll bridge in the Sei Batang Serangan riverside. Based on hydraulic analysis using the HEC-RAS 5.0 program from steady flow data, the maximum water level elevation is at River Sta 5+00 of 10.52 m in a 50-year return period, and the minimum water level elevation is at River Sta 2+00 of 4.45 m in a 2-year return period. Thus, based on the flood water level of 12.691 meters, the Sei Wampu toll bridge area does not have flood inundation because the water level elevation value does not exceed the flood water level value (TMA < MAB). Meanwhile, from the results of the steady flow data analysis, it can be concluded that no flooding occurred at the Sei Batang Serangan toll bridge in the Sei Batang Serangan riverside at a known return period.

Abstract

The problem of flooding is one of the important tasks that must be completed in the city of Medan. Flood disasters have the potential to cause casualties, so it is important to know the level of community readiness in dealing with flood disasters. This study aims to include the involvement of the community in flood-prone areas in the city of Medan and compare the readiness of each urban districts in dealing with floods. This has a long-term goal to minimize the negative impact of flooding in the city of Medan with a bottom-up approach. The research will use a quantitative approach, namely a questionnaire to 200 respondents consisting of households that are in flood-prone locations at several points in the city of Medan. The primary data obtained from the questionnaire will be analyzed and tested for face validity. The final result of the research is expected to be able to project the level of community readiness in the city of Medan in dealing with floods and become a reference for policy makers related to flood disaster management in the city of Medan. It can be concluded from the preliminary result that Aur Urban Village has the highest value in terms of level of preparedness in comparison to the other 9 urban villages. The informality of Aur Urban Village is argued to have a significant correlation with the high level of preparedness from the residents in Aur Urban Village. keywords: Flooding, community readiness, disaster management, preparedness, buttom-up approach.

Abstract

The area around the Universitas Sumatera Utara Campus, Medan city, is an area that is often hit by floods, especially when there is quite heavy rain with a fairly long duration. Based on initial observations, it can be said that this is due to the drainage channel being unable to accommodate the high rainwater discharge. To overcome this, the 2021 USU TALENTA Community Service Program offered a solution by creating a sustainable drainage system that is environmentally insight. The solution starts with the smallest thing that each household in the affected area can do, namely through making biopori holes. In addition to biopori, another solution taken is through the construction of infiltration wells and groundwater tanks. Conducted training and simulation activities on these three solutions of environmentally sustainable drainage systems. It is hoped that it will gradually reduce water runoff directly into the city drainage, but the water can be partially absorbed into the ground first, to reduce standing water which can eventually cause flooding.

Abstract

Indonesia has significant water resources potential for the development of hydropower plants, including the Batang Toru River with a power potential of 510 MW that has not yet been fully utilized. This study aims to analyze the hydrological potential of the Batang Toru River, calculate the potential electricity generation capacity, and evaluate the potential reduction of carbon emissions to support sustainable and environmentally friendly hydropower operations. The research methods include literature review, collection of historical rainfall and river discharge data, hydrological analysis to determine reliable discharge, hydraulic analysis to calculate the effective head, and simulation of the potential power generation capacity. The results show that the 90% reliable discharge (Q90) of 72.67 m³/s is insufficient to meet the 510 MW power demand, thus requiring the construction of a reservoir with a design discharge of 219.494 m³/s. With this discharge, the Batang Toru Hydropower Plant can generate 510 MW of electricity and is estimated to reduce carbon emissions by 1,326,645 tons per year. This study recommends expanding hydrological data coverage, utilizing GIS-based modeling technology, and conducting economic feasibility and environmental impact analyses to improve the efficiency and sustainability of the hydropower plant

Abstract

Kantong lumpur merupakan komponen penting dalam sistem irigasi karena mengendapkan sedimen sebelum air memasuki saluran primer. Pada Daerah Irigasi Paya Lombang, sedimentasi dan pertumbuhan vegetasi menunjukkan perlunya evaluasi kapasitas serta kinerja bangunan kantong lumpur Bendung Sei Padang. Penelitian ini bertujuan mengidentifikasi karakteristik sedimen, menentukan kecepatan jatuh partikel dan aliran, menghitung volume sedimen masuk, serta mengevaluasi kapasitas dan efisiensi kantong lumpur. Penelitian dilakukan melalui survei lapangan, pengambilan sampel sedimen, dokumentasi, pengumpulan data hidraulik sekunder, dan pengujian laboratorium. Analisis meliputi analisis saringan dan hidrometer, klasifikasi tekstur tanah USDA, pengujian kecepatan jatuh, pengukuran konsentrasi sedimen layang, perhitungan angkutan sedimen dengan metode Lane dan Kalinske, serta evaluasi hidraulik berdasarkan kriteria KP-02, Shield, dan Camp. Hasil menunjukkan bahwa sedimen pada sebagian besar lokasi berupa sandy loam, sedangkan bagian tengah kantong lumpur bertekstur sandy dan saluran primer bertekstur loam. Kecepatan jatuh rata-rata sedimen dalam kantong lumpur mencapai 0,0050 m/detik. Kapasitas perhitungan sebesar 3.942,144 m³ memerlukan lebar 10,123 m, lebih besar daripada lebar eksisting 5,20 m; namun, rasio panjang terhadap lebar sebesar 10,866 masih memenuhi persyaratan KP-02. Volume eksisting 135,85 m³ melebihi volume sedimen selama 14 hari sebesar 41,86 m³, sehingga pembilasan dua mingguan masih memadai. Efisiensi pengendapan mencapai 85%, kondisi turbulensi dinyatakan aman, dan tegangan geser dasar 6,078 N/m² memungkinkan pembilasan partikel berdiameter kecil. Sekitar 5,8% sedimen layang dari hulu bendung masuk ke kantong lumpur. Dengan demikian, kapasitas volume dan operasi pembilasan masih mencukupi, tetapi keterbatasan lebar, sedimentasi, vegetasi, dan pengoperasian pintu intake memerlukan pemeliharaan serta pengendalian yang lebih konsisten secara berkelanjutan dalam pengelolaan irigasi setempat.

Abstract

Program Mahasiswa Berdampak dilaksanakan di Desa Aek Ngadol Nauli, Kabupaten Tapanuli Selatan, sebagai respons atas bencana hidrometeorologi 25 November 2025 yang berdampak pada aspek fisik, sosial, dan ekonomi masyarakat. Mitra sasaran utama adalah Kelompok Satahi II (pengelola Lubuk Larangan) dan Lembaga Pemberdayaan Masyarakat Desa (LPMD). Kedua mitra mengalami kelumpuhan fungsi pascabencana, terutama dalam pengelolaan sumber daya dan kelembagaan sosial. Permasalahan utama meliputi hilangnya Lubuk Larangan akibat kerusakan ekosistem sungai serta melemahnya aturan kolektif (rules-in-use), partisipasi sosial, dan modal sosial masyarakat. Program ini bertujuan memulihkan fungsi kelembagaan lokal melalui revitalisasi Lubuk Larangan dan konsolidasi sosial berbasis modal sosial. Metode yang digunakan adalah pendekatan partisipatif melalui pendampingan, FGD, wawancara, observasi, dan pendekatan persuasif. Hasil menunjukkan bahwa Lubuk Larangan berhasil diaktifkan kembali secara simbolik dan sosial, LPMD kembali berfungsi sebagai penggerak kolektif, serta terjadi penguatan partisipasi masyarakat. Selain itu, kegiatan psikososial dan inovasi ketahanan dapur berbasis polybag memberikan kontribusi terhadap pemulihan sosial-ekonomi. Program ini menunjukkan bahwa penguatan institusi lokal berbasis kearifan lokal merupakan strategi efektif dalam pemulihan pascabencana
