Abstract

Kondisi curah hujan yang tinggi khususnya negara tropis sering menyebabkan terjadinya banjir atau genangan di ruas-ruas jalan, terutama jalan perkotaan. Genangan yang tidak masuk atau terhambat dapat mengakibatkan kerusakan pada jalan. Hal ini dapat di tanggulangi dengan desain inlet pada saluran drainase jalan raya yang sesuai dengan kondisi dilapangan. Dengan memperhatikan jarak antar inlet, dimensi, dan jenis inlet disesuaikan dengan debit air hujan dan lebar jalan yang ada. Street Inlet ini merupakan lubang di sisi-sisi jalan yang berfungsi untuk menampung dan menyalurkan limpasan air hujan yang berada di sepanjang jalan menuju ke dalam saluran drainase..Penelitian dilakukan pada sebuah prototype yang menggambarkan kondisi ruas jalan raya dengan modifikasi street inlet seperti kondisi di lapangan. Metode analisis debit limpasan permukaan di gunaan metode rasional, analisis dimensi inlet di gunakan kaidah hidrolika yang berlaku. Adapun data input yang di gunakan ialah data curah hujan, jenis jalan, jenis inlet street, limpasan hujan atau genangan, kondisi saluran drainase, regresi linier. Penelitian ini membahas tentang kinerja inlet jalan untuk mengurangi genangan akibat limpasan hujan (dengan model street inlet persegi panjang di bahu jalan). Pada penelitian yang dilakukan jenis inlet yang akan di gunakan ialah gutter inlet yang mempunyai bukaan horizontal. High rainfall condition, especially in tropical countries, often cause flooding or inundation on road section, especially urban road. Puddles that do not enter or are hampered can cause damage to the road. This can be overcome by the inlet design of the road drainage channel that is suitable for the conditions in the field. By paying attention to the distance between inlets, dimensions, and inlet types adjusted to the rainwater discharge and the width of the existing road. Street Inlet is a hole on the sides of the road that serves to accommodate and distribute rainwater runoff along the road leading into the drainage channel.The research was carried out on a prototype that describes the condition of the highway with street inlet modifications such as conditions in the field. The method of analyzing surface runoff in the use of rational methods, inlet dimension analysis is used in the applicable hydraulic rules. The input data used are rainfall data, type of road, type of inlet street, rain runoff or inundation, drainage channel conditions, linear regression. This study discusses the performance of the road inlet to reduce inundation due to rain runoff (with a model of a rectangular inlet on the shoulder of the road). In the research carried out the type of inlet that will be used is the gutter inlet which has a horizontal opening.

Abstract

This research was conducted at SPAMDes (Sistem Penyediaan Air Minum Pedesaan) Tirta Lestari which is located in Kaliapak, Banjarsari, Samigaluh, Kulon Progo. This study discusses the water availability from SPAMDes Tirta Lestari for 10 years later. The purpose of this research to determine the capacity of customers that can be served with existing source water discharge and predict the final year that can be served with the growth of customers and existing source water discharge. This research method uses least square and geometric methods in predicting population growth. Analysis of water demand takes into water losses of 15% and 37%. The results of this study in 2031 SPAMDes Tirta Lestari can serve with a total of 85 home connections (SR) customers with a total water need of 0.32 liters / second (loss of 15%) and 0.37 liters / second (loss of 37%). The number of customers who can be served with a source water discharge of 0.89 liters / second is 109 SR (loss 15%) and 100 SR (loss 37%).

Abstract

Abstrak Pemenuhan air bersih meliputi sumber air, sistem pengolahannya dan distribusinya. Sistem distribusi air bersih yang belum terencana dengan tepat akan membuat air bersih tidak sampai kepada masyarakat. Hal inilah yang menjadi hambatan dalam pengelolaan air bersih, khususnya yang dikelola secara mandiri oleh masyarakat. Oleh karena itu, penelitian ini bertujuan untuk menganalisis sistem distribusi air bersih yang ada di Desa Mantren, Magetan. Perencanaan jaringan dilakukan dengan menggunakan software Epanet 2.0. Sumber air direncanakan menggunakan sumur bor dengan debit rencana 1,95 liter/detik. Tipe pengaliran menggunakan gravitasi dari tampungan air dengan ketinggian tertentu. Hasil analisis menunjukkan bahwa ketinggian tampungan air yang disarankan adalah 11 meter dari permukaan tanah. Jumlah kebutuhan pipa sebanyak 55 buah. Dengan desain jaringan air yang telah dibuat, diperoleh tekanan air dalam pipa dan kecepatan aliran telah memenuhi persyaratan yang dikeluarkan Kementerian Pekerjaan Umum pada tahun 2007. Tekanan air dalam pipa berkisar 5-80 meter dan kecepatan aliran berkisar 0,3-4,5 m/detik. Hasil penelitian ini diharapkan mampu menjadi bahan rekomendasi teknis dalam perencanaan sistem distribusi air oleh warga setempat. Kata-kata kunci:  Epanet 2.0, sistem distribusi, tekanan air, dan kecepatan aliran. Abstract Fulfillment of clean water includes water sources, processing systems and distribution. A clean water distribution system which is not properly planned may lead to problems in accessibility. This is a very common problems in water distribution system, especially for that is managed and owned by the community. Therefore, this research aims to analyze the clean water distribution system in Mantren Village, Magetan. Network planning is carried out using Epanet 2.0 software. The water source is planned to use a drilled well with a planned discharge of 1.95 liters/second. The water is pumped to the reservoir tank and distributed to the people by gravity force. The analysis results show that the recommended height of the reservoir tank is 11 meters from the ground surface. The number of required pipes is 55 pieces. The water pressure in the pipes and flow velocity have met the requirements issued by the Ministry of Public Works in 2007. The water pressure is in the range of 5-80 meters, while the flow velocity is in the range of 0.3-4, 5 m/sec. The results of this research is expected to provide technical recommendations in planning water distribution systems by local residents. Keywords:  Epanet 2.0, distribution system, water pressure, and flow velocity
