Abstract

Air merupakan sumber daya alam yang sangat berharga karena tanpa air tidak mungkin terdapat kehidupan. Sejalan dengan perkembangan zaman dan penduduk yang terus meningkat maka kebutuhan akan ketersediaan air baku juga akan semakin meningka. Medan merupakan salah satu kota terbesar di Indonesia yang memiliki tingkat kepadatan penduduk yang tinggi. Meningkatnya jumlah penduduk membuat daerah resapan air menjadi berkurang oleh karena berubah menjadi pemukiman dan perhotelan. Metode rainwater harvesting atau metode memanen air hujan adalah suatu cara menampung air hujan yang jatuh ke bumi untuk dimanfaatkan kembali dan digunakan untuk berbagai fungsi. Metode ini sudah dikenal sudah sejak lama dan telah dilakukan oleh manusia terdahulu hingga manusia pada abad sekarang. Air hujan dikelola dan dapat langsung digunakan atau disambungkan ke jaringan perpipaan air bersih sebagai air cadangan. Untuk menganalisa curah hujan digunakan data pencatatan curah hujan Tahun 2009 – 2018 dari Stasiun Pencatat Hujan Padang Bulan, Medan. Hasil penelitian menunjukkan bahwa jenis distribusi yang sesuai untuk sebaran data di kota Medan adalah distribusi Log Pearson Type III dengan jumlah air yang dapat dipanen pada atap sekolah melebihi batas tangki yang dipakai yakni tangki 500 L.

Abstract

Kawasan Jalan Dr. Mansyur yang merupakan salah satu lokasi tempat tinggal, tempat usaha atau bekerja maupun tempat menuntut ilmu masih menemui berbagai permasalahan yang harus segera dibenahi. Masalah yang selalu dialami adalah ketika curah hujan tinggi di kawasan tersebut terjadi genangan air di badan maupun di bahu jalan serta kurang berfungsinya saluran drainase yang akhirnya menyebabkan tidak mengalirnya aliran drainase pembuangan limbah yang mengakibatkan kegiatan dan aktifitas penduduk maupun pengguna jalan terganggu. Studi ini dilakukan dengan mengacu pada data sekunder. Data curah hujan diambil dari Balai Wilayah Sungai Sumatera I. Analisis data untuk mendapatkan intensitas curah hujan yaitu dengan menggunakan Rumus Mononobe dan debit banjir dengan menggunakan Rumus Metode Rasional. Nilai curah hujan digunakan untuk perhitungan intensitas curah hujan adalah nilai rata-rata curah hujan harian maksimum tahun 2007-2016 Pos Helvetia Kota Medan. Perhitungan debit eksisting pada aliran hulu Sungai Putih tepatnya di Jl. Dr. Mansyur (Simpang Jl. Pembangunan) adalah 14,84 m3/det dimana lebih kecil dari debit banjir rencana dengan kala ulang 2 tahun yaitu 14,95 m3/det; 5 tahun yaitu 16,79 m3/det; 10 tahun yaitu 17,83 m3/det; 25 tahun yaitu 19,02 m3/det; 50 tahun yaitu 19,83 m3/det. Direncanakan lubang resapan biopori sebanyak 125 lubang dengan diameter 10 cm dan kedalaman 200 cm. Satu lubang biopori mampu mengalirkan air kedalam tanah sebanyak 40 l/det atau 0,04 m3/det. Debit total yang mampu ditampung yaitu 5000 l/det atau 5 m3/det. Ini dapat menjadi solusi untuk menangani banjir di wilayah tersebut.

Abstract

Penggunaan beton porous pada lantai laboratorium merupakan salah satu upaya yang akan dilakukan untuk mengatasi genangan akibat tumpahan air dari peralatan laboratorium. Beton porous yang akan digunakan harus memiliki nilai permeabilitas dan porositas yang terukur guna mengoptimalkan fungsi penggunaan beton porous tersebut. Nilai permeabilitas dan porositas beton porous dipengaruhi oleh beberapa faktor, salah satu faktor tersebut adalah ukuran gradasi agregat.Komposisi pembuatan beton porous mengacu pada mix design yang digunakan oleh Holcim Singapore. Agregat yang digunakan adalah aggregat alam dengan variasi gradasi tidak seragam  berdiameter 19.00 mm(#3/4), 12.50 mm(#1/2), dan 9.50 mm(#3/8). Sampel dibuat menjadi tiga variasi gradasi agregat dengan perbandingan (1(#3/4):2(#1/2):1(#3/8)); (2(#3/4):1(#1/2):1(#3/8); dan (1(    #3/4):1(#1/2):2(#3/8). Masing-masing 5 sampel. Sampel berbentuk silinder berdiameter 4 inci dengan ketebalan 15 cm.Nilai Permeabilitas rata-rata terbesar terjadi pada variasi campuran gradasi agregat (1(#3/4) : 2(#1/2) : 1(#3/8)) sebesar 0,58 cm/det dengan porositas rata-rata 7,35 %. Variasi gradasi agregat dalam penelitian ini tidak mempengaruhi permeabilitas dan porositas secara signifikan.

Abstract

Drainage is one of the infrastructure facilities for people’s lives in urban areas, but unfortunately there are many drainages that do not function properly so that drainage seems useless. One of the functions of drainage is as a building to prevent flooding and control water in an area, but in fact floods still occur, one of which is in the Kampung Lalang area, where one of the causes is the mismatch between the flood discharge and the size of the channel dimensions. Biopore infiltration drainage is one solution to overcome this problem where some of the overflow water will be returned to groundwater.

Abstract

ABSTRAKPelabuhan Belawan merupakan pelabuhan terbesar di Sumatera dan ketiga terbesar di Indonesia setelah Tanjung Priok dan Tanjung Perak. Pelabuhan Belawan berada didaratan semenanjung diantara Sungai Belawan dan Sungai Deli. Modelisasi pada pola arus di Pelabuhan Belawan akan menemui masalah yang sangat kompleks, karena geometri daerah pantai yang tidak beraturan adalah bagian sungai yang berhubungan langsung dengan laut. Pengaruh pasang surut terhadap sirkulasi kecepatan pola arus dan debit sungai yang masuk ke Pelabuhan Belawan sangat besar.  Salah satu model matematik untuk pemecahan masalah diatas adalah melakukan kajian dengan menggunakan software SMS (Surface-Water Modeling System) versi 11.1 pada modul RMA2, untuk mengetahui elevasi muka air pada titik di hulu dan hilir pelabuhan pada saat spring tide dan neap tide di musim basah (November) dan musim kering (Juli). Berdasarkan hasil yang didapatkan, kecepatan arus saat pasang tertinggi di musim basah adalah 0,04367 m/s - 0,4608 m/s, kecepatan arus saat pasang terendah di musim tersebut adalah berkisar antara 0,00028 m/s – 0,00287 m/s. Sedangkan kecepatan arus saat pasang tertinggi pada musim kering adalah 0,0229 m/s - 0,2744 m/s dan kecepatan arus saat pasang terendah adalah 0,0003 m/s – 0,0019 m/s. Kecepatan arus pada musim basah cenderung lebih besar daripada musim kering, disebabkan karena pengaruh pasang surut dan debit yang besar, meskipun pada simulasi angin dianggap konstan, tidak menutup kemungkinan bahwa pengaruh tekanan angin pada pelabuhan mempengaruhi kecepatan aliran.Kata Kunci : Eddy Viscosities, Pelabuhan Belawan, Pola Aliran, SMS v11.1 ABSTRACTBelawan Port is the largest port in Sumatra and the third largest in Indonesia's after the Tanjung Priok and Tanjung Perak. Belawan Port is located in mainland peninsula between Belawan and Deli river.The modeling of flow pattern in Belawan Port will encounter a very complex problem, because of the irregular geometry of coastal area which is directly connected to the sea. Tidal influence on flow circulation and the river discharge into Belawan Port is very significant. One of the mathematical models to solve the above problem is aimed to study the use of SMS software (Surface-Water Modeling System) version 11.1 on RMA2 module, to determine the water level at port including upstream and downstream during spring tide and neap tide on the wet season (November) and the dry season (July). Based on the obtained results, the flow velocity of the highest tide on the wet season is 0.04367 m/s - 0.4608 m/s, the flow velocity of the lowest tide on the dry season is between 0.00028 m/s  and 0.00287 m s. While the flow velocity of the highest tides on the dry season is 0.0229 m/s - 0.2744 m/s and low tide flow velocity is 0.0003 m/s - 0.0019 m/s. Flow velocity on the wet season tends to be larger than the dry season due to the influence of tide and large discharge. Although the wind is considered constant on this simulation, it is possible that the wind pressure against the port affects the flow velocity. Keywords: Belawan Port, Eddy Viscosities, Flow Pattern, SMS v11.1

Abstract

The scientific study of the integrated utility network in the city of Medan, and the mapping of safety locations in the city of Medan. The title of the study became the initial discussion material to formulate the focus of research in the infrastructure sector on the most urgent (important) infrastructure problems found in the city of Medan inventory of drainage flow dimensions and patterns, Measurement of drainage channel base elevation, Inventory of public perceptions of water management and drainage systems, Analysis of hydrology Hydraulic analysis and social analysis of society. It was found that there were 2 sewers on Jalan Cempaka, but the dimensions that changed significantly resulted in being unable to accommodate runoff from upstream. The sewer at the District Office is at the lowest elevation and becomes a collection of flows from various directions. The second sewer near the leafy Glugur road is suffering from the settlement. The impact of land-use change without knowing the function of the natural channel has an impact on the closure of the natural discharge channel, thus affecting the pattern of runoff. Selayang River is one of the causes due to the low channel dimensions. Irregular channel size is related to flooding problems due to river overflow, it is necessary to normalize the river by considering the potential that exists in each river. Flood problems also require handling from upstream to downstream. Solving the problem of air and flood problems requires clear regulations. For this reason, appropriate regulations are needed for solving water and flood problems at the level of policies or regulations of the Medan City Government.Keywords: Accompaniment, Network research, development, infrastructure,

Abstract

The Bo'u Lahomi-West Nias Bridge is a bridge that spans 11.80 m. The sub-structure of the bridge consists of abutments and foundations. This evaluation was conducted to determine the bearing capacity of the well foundation and the safety factor against the working load along with an evaluation of the analysis of the amount of foundation reinforcement and pile cap. The safety factor for the bearing capacity of the well foundation is determined based on the comparison of the bearing capacity value of the well foundation > with the maximum load value that works on the foundation, while the safe factor for pile cap reinforcement and the well foundation is determined based on the strength value of the column > with the maximum load value received. In addition to field data, this analysis requires testing of soil parameters in the laboratory. The meters tested were specific gravity (Gs), filter analysis of moisture content, density, direct shear strength of the soil in the field. Based on the results of the analysis of the bearing capacity of the well foundation, it was found that the value of the bearing capacity of the pile foundation group was 2510,78 tons and the maximum load acting on the foundation was 1550,40 tons. 15 13, and shear reinforcement in the direction of X 10 – 140 and Y 10 – 100 and analysis of reinforcement on the well foundation obtained 35 D 19-250 principal reinforcement and spiral reinforcement 12 – 50 with a column strength of 7654.153 Ton > Pu = 1550.40 Tons, thus the bearing capacity of the well foundation on the bo'u bridge meets the requirements and is safe against the load received and the column cross-sectional design meets the requirements so that the size of the piles and reinforcement can be used.
