Abstract

Permasalahan banjir merupakan salah satu permasalahan umum yang sering terjadi di sebagian wilayah Indonesia, misalnya di PT.HANIL JAYA STEEL. Perkembangan industri baja terjadi karena adanya kebutuhan konsumsi baja fabrikasi yang pesat, yang membutuhkan berbagai infrastruktur baru seperti pengaturan drainase dan lain-lain. Lahan yang semula rendah dan kosong ditimbun untuk dibangun berbagai infrastruktur dan kawasan PT.HANIL JAYA STEEL menjadi semakin berkembang. Perkembangan PT.HANIL JAYA STEEL ternyata diikuti oleh munculnya genangan banjir dibeberapa tempat, hal ini terjadi karena perkembangan kawasan tidak diikuti oleh pembangunan sistem drainase nya yang memadai. Saluran drainase yang kurang memenuhi syarat sehingga pada saat elevasi air Sungai yang berada disekitar kawasan pabrik tidak dapat berfungsi lagi. Akibatnya setiap musim hujan PT.HANIL JAYA STEEL selalu tergenang banjir. Untuk mengatasi genangan banjir penampang saluran pada sistem drainase PT.HANIL JAYA STEEL harus diredimensi. Untuk menormalisasi jaringan saluran drainase telah dihitung Kapasitas maksimum saluran (Full bank capacity), dan debit banjir rencana. Saluran drainase tersier direncanakan dengan debit banjir periode ulang 2 tahun, saluran sekunder dengan periode ulang 5 tahun dan saluran drainase primer direncanakan dengan debit banjir periode ulang 10 tahun. Perbandingan antara besarnya kapasitas maksimum saluran dengan debit banjir rencana, menunjukkan bahwa sistem drainase PT.HANIL JAYA STEEL terjadi luapan banjir. Hal ini menunjukkan bahwa sebagian besar penampang saluran eksisting terlalu kecil sehingga harus diredimensi berdasarkan debit banjir rencana. Untuk merencanakan dimensi saluran menggunakan rumus Manning. Selain itu, penanggulangan banjir harus dilakukan secara komprehensif dengan mempertimbangkan beberapa studi kelayakan seperti aspek teknis, sosial, ekonomi, hukum, kelembagaan dan lingkungan. Oleh karena itu, kerjasama dan perencanaan penanggulangan banjir PT.HANIL JAYA STEEL sangat di perlukan dalam penanggulangan banjir dengan cara redimensi saluran eksisting ================================================================================================================== The problem of flooding is one of the common problems that often occur in parts of Indonesia, such as in PT.HANIL JAYA STEEL. The development of the steel industry occurs because of the need for rapid fabrication of steel consumption, which requires a variety of new infrastructure such as drainage arrangements and others. The land which was originally low and empty stockpiled for built infrastructure and neighborhood JAYA STEEL PT.HANIL be growing. PT.HANIL development JAYA STEEL turns followed by the rise of floodwaters in some places, this is because the development of the region is not followed by the construction of its adequate drainage system. Drainage less qualified so that when the river water elevation is around the area of the factory can not work anymore. As a result, every rainy season PT.HANIL JAYA STEEL always flooded. To cope with the floodwaters cross section of the channels on the drainage system must diredimensi PT.HANIL JAYA STEEL. To normalize the drainage channel network has calculated the maximum capacity of the channel (Full bank capacity), and the flood discharge plan. Tertiary drainage channels planned to discharge flood return period of 2 years, the secondary channel with a return period of 5 years and the primary drainage channel is planned to discharge flood return period of 10 years. The comparison between the magnitude of the maximum capacity of the channel with the flood discharge plan, shows that the drainage system PT.HANIL JAYA STEEL outburst flood occurs. This indicates that most of the existing channel cross section is too small and should be diredimensi by flood discharge plan. To plan the dimensions of the channel using the formula of Manning. In addition, flood prevention should be done in a comprehensive manner by considering several feasibility studies as technical aspects, social, economic, legal, institutional and environmental. Therefore, cooperation and planning for flood prevention PT.HANIL JAYA STEEL is in need in flood prevention by way of re-dimension the existing channel
