ABSTRAK

Kondisi sistem drainase Gunungsari Sememi Kali Lamong pada umumnya belum berfungsi dengan baik sebagai sarana pembuangan air. Hal ini dapat diketahui dengan adanya genangan di beberapa wilayah pada waktu hujan sebagai akibat dari daya tampung saluran yang tidak memadai. Sebab lain adalah perubahan tata guna lahan didaerah tersebut sehingga mengurangi daerah resapan air di sekitar kali Sememi. Dengan adanya permasalahan tersebut maka perlu adanya perencanaan Saluran Gunungsari Sememi Kali Lamong. Dengan cara melakukan upaya perbaikan sistem drainase berdasarkan perhitungan hujan rencana dengan metode Pearson Type III dan perhitungan debit rencana Q5 dengan Metode Hidrograf Satuan Sintetik Snyder Alexejev. Serta menggunakan perhitungan coba - coba untuk mengetahui kapasitas yang bisa ditampung oleh saluran tersebut. Dari hasil perhitungan didapatkan perencanaan sistem drainase Gunungsari Sememi Kali Lamong dengan kapasitas tampung total Q 60.60 m3dt. Debit tersebut dihasilkan dari Saluran Sememi Selatan Saluran Babat Jerawat dan Kali Benowo. Untuk saluran ruas Sememi - Babat Jerawat Benowo menggunakan penampang persegi sedangkan untuk saluran Benowo Kali Lamong enggunakan penampang trapesium.


ABSTRACT

The Condition of drainage system Gunungsari Sememi Lamong River generally not function well as a means of disposal of water.This can be known by thepool in some areas in the rain as a result of the channel capacity is not adequate.Another cause is the change in land use such areas thereby reducing thewater catchment areas around Sememi times. Given these problems it is necessary to the planning Gunungsari Channel Sememi Lamong River.By way of system improvement efforts based on the calculationof rain drainage plan with Pearson Type III method and calculation capacity Q5 plan with Hidrograf Method Snyder synthetic unit - Alexejev.. And using alculations try - try to find out the capacity that can be accommodated by the channel. From calculation results obtained from the planning of drainage systems Gunungsari Sememi Lamong River with a total capacity of capacity Q 60.60 m3 dt. The capacity is generated from South Sememi Channel Babat Jerawat Channel and Benowo Channel.To channel segment Sememi Channel - Babat Jerawat Channel Benowo Channel using square cross-sectionwhile for the Benowo Lamong River using trapezoidal cross-section.
