Abstract

People who still live in the area around the river, even after the flood disaster is a matter of concern. The perceptions and preferences of the community are very influential when choosing a place of residence. Basically, these perceptions and preferences are shaped by their knowledge or understanding of the objects that will be perceived, as well as the main reason people choose their current residence, which in this study is the river border area in the Manado City Bailang Kelurahan. The majority of the inhabitants of the river border region that suffered flooding in January 2023 chose to remain in the rivers border area, even though they were aware of the dangers that might arise later on. The aim of this research is to find out the perceptions and preferences of the people who live around the border of the Bailang river so that they can continue to live there. This research uses quantitative methods with descriptive analysis. The conclusion derived from the perceptions and preferences of the population is that they chose to settle in the river boundary area in the Bailang District of the City of Manado, because many local people do not understand about river border areas, the establishment of river borders, the distance of establishing river lines on either river-boundary or non-border river, then does not understand the purpose of the rivers border area and the people hear from others information obtained about rivers boundaries area and some have also heard of socialization from the government. People who choose to stay in the River Border Area because there is no other land for them to build houses and also in the place where they now have cheap land prices.

Abstract

Rivers are often used as a water source for agriculture, transportation, and water supply needs. One of the causes of riverbank damage is scouring the cliff's foot, which cannot withstand scouring currents. If not addressed immediately, it will cause more severe damage. Citarum River is one river that passes through Atirompe Village, Majalaya District. The riverbanks in the area have a risk of cliff failure. The study objective was to analyze the problem, design the protection, and calculate the budget. The hydrology and riverbank analysis of the Majalaya River has been performed. The steps were essential to analyze the depth and width of the scour caused by the flow of the Citarum River water. Sediment data were collected at three locations, namely the upstream, middle, and downstream of the river segment that will be reviewed. In data processing, to obtain a sediment rating curve, it is necessary to measure the flow velocity, which will later be calculated and used as the flow rate during Total Suspended Solid (TSS) data collection. Using the Hydrology Engineering Center – River Analysis System (HEC – RAS) 6.2 software, the calculations with the Ripley Equation were compared to obtain the scour depth. For the design alternative, constructing a steel sheet pile-type cliff protection structure is one form of planning to protect riverbanks. This study also analyzed the recapitulation of the budgeting for protecting the Citarum riverbanks in Atirompe Village, Majalaya District. Using a standardized unit price, the total cost for the protection is 1.8 billion rupiahs.
