Abstract

Tidal flood is a disaster that threatens coastal areas due to sea-level rise and land subsidence. One of the sub-districts in the city of Semarang, which is included in the tidal flood-prone area in every years, is the North Semarang Sub-District. The area of tidal flood is 55.95 Ha and the data of estimated generation of tidal flood waste in the North Semarang Sub-District is +/- 70 tons. Lack of planning for handling waste disasters, especially for tidal flood waste, is a challenge related to environmental and economic impacts that occur at tidal flood sites. This study aims to examine the quantification of the cost of handling tidal flood waste using quantitative descriptive analysis cost accounting calculation method. The calculation is done by considering several things, namely the activity of handling waste, the need for handling waste, as well as the calculation of the cost of handling tidal flood waste. The total cost of handling tidal flood waste in North Semarang Sub-District is IDR 14,209,324,000/year or IDR 1,184,110,333/month. The results of the calculation of the overall cost are then divided by the area of the tidal flood so that the unit cost of handling waste per m2 is IDR 2,117/m2.

Summary

Introduction

Study of Tidal Flood Waste Management Cost in North Semarang Sub-District. Tidal flood is a disaster that threatens coastal areas due to sea-level rise and land subsidence. The total cost of handling tidal flood waste in North Semarang Sub-District is IDR 14,209,324,000/year or IDR 1,184,110,333/month. It can be seen that the sea surface conditions in Semarang waters that have experienced such changes have caused the impact of overflowing water or commonly referred to as tidal floode. In terms of land subsidence aspects from map observations from 2000 to 2010, the Semarang area experienced a decrease of 1 cm/year to 9 cm/year This condition shows that the coastal area, including North Semarang Sub-District, has a high vulnerability. Addition conditions to sea level rise and land subsidence will have an impact on areas prone to flooding in the city of Semarang, especially in the North Semarang Sub-District
