Abstract

The East Semarang watershed is an area with diverse land conditions and the majority of the upstream and downstream areas are converted into settlements. This results in an increase in the rate of erosion which erodes the land and causes sedimentation in the downstream watershed. The higher the erosion rate, the higher the sedimentation, therefore the prediction of the erosion value is important as an indicator to recommend natural resource conservation activities. The purpose of this study is to predict erosion and sedimentation rates, and to recommend good conservation methods in an effort to reduce soil erosion. Land erosion analysis was obtained from the overlay of erosion parameter layers with the help of the ArcGIS program using the USLE (Universal Soil Loss Equation) method. Not all of the eroded soil surface in the watershed will be transported to the river, but some will settle on the watershed surface due to the interaction between the flow and the watershed surface. Sediments carried by measured river flows at the outlet were analyzed using the SDR (Sediment Delivery Ratio) method. Then it can be known the amount of sediment per year in the East Semarang watershed or by the term SY (Sediment Yield). Based on the calculation of land erosion in the East Semarang watershed, as big as 816,910.81 tons/year, which resulted in a total sedimentation of 4,641.39 tons/year. Erosion hazard classifications vary from very light to very severe, with the majority of the class being very severe in the upstream region with an area of ​​7,003.55 Ha. The recommendation proposed to overcome or reduce erosion is technical conservation, namely terracing and check dam techniques.

Abstract

Air merupakan kebutuhan dasar manusia yang paling penting. Air memegang peranan penting bagi kehidupan manusia karena dapat digunakan oleh manusia untuk keperluan sehari-hari seperti minum, mandi, cuci, dan kakus. Sistem distribusi air bersih merupakan suatu jaringan perpipaan yang tersusun atas sistem pipa, pompa, reservoir dan perlengkapan lainnya. Sistem penyediaan air bersih sering mengalami masalah dalam hal debit maupun tekanan yang berkaitan dengan kriteria hidrolis yang harus dipenuhi dalam sistem pengaliran air bersih. Salah satu bagian terpenting dari sistem penyediaan air bersih adalah jaringan distribusi. Permasalahan yang terjadi di wilayah Desa Kandangan yaitu minimnya debit pada waktu-waktu tertentu pada beberapa titik rumah. Untuk pendistribusiannya diperlukan pipa saluran primer yang menghubungkan sumber air dengan pipa saluran sekunder. Pipa saluran sekunder ini yang digunakan untuk menyalurkan air dari pipa saluran primer ke rumah setiap warga. Sangat disayangkan hingga saat ini air tersebut belum terdistribusi secara maksimal ke rumah-rumah warga dikarenakan keterbatasan biaya yang dimiliki warga. Oleh karena itu diperlukan adanya pemasangan pipa saluran primer maupun sekunder untuk menyalurkan air bersih tersebut. Untuk pipa saluran yang menghubungkan langsung ke rumah warga merupakan tanggung jawab masing-masing kepala keluarga sesuai dengan hasil musyawarah warga Desa Kandangan. Pendistribusian air bersih ke wilayah warga menggunakan sistem gravitasi.
