Abstract

Climate change has led to an increase in rainfall intensity and uncertainty, which has significantly contributed to the rising occurrence of urban flooding. One of the main causes of flooding in urban areas is the inadequacy of drainage systems that were designed based on outdated hydrological data. In urban drainage planning, mathematical models play an important role in analyzing rainfall characteristics, estimating runoff discharge, and determining appropriate drainage channel capacity. This study aims to analyze the role of mathematical models in urban drainage planning as an effort to mitigate flood risks in the era of climate change. The methods used include rainfall data analysis, determination of design rainfall intensity, runoff discharge calculation using the Rational Method, and evaluation of drainage channel capacity based on open channel flow principles. The results indicate that the application of appropriate mathematical models can improve the accuracy of drainage system planning and reduce the potential for surface water inundation. Therefore, the systematic use of mathematical models is essential to develop more adaptive and sustainable urban drainage systems.

Abstract

This study aims to analyze the types and structural systems of traditional residential houses in Nias and to understand their characteristics, functions, and cultural values. The research employs a descriptive qualitative approach with data collection techniques including observation, interviews, and documentation conducted in several traditional villages on Nias Island. The results show that traditional houses in Nias are generally classified into two main types, namely Omo Hada and Omo Sebua, which differ in terms of size, structural complexity, and social function. The structural system utilizes a stilt-house construction with wood as the primary material and joinery techniques without nails, providing high flexibility against dynamic loads such as earthquakes. Furthermore, the use of local materials such as hardwood and thatched leaves reflects local wisdom in sustainable construction practices. However, modernization and changes in community lifestyles have led to a decline in the number of authentic traditional houses. Therefore, preservation efforts are needed through an integrative approach that combines traditional values with modern technology to ensure the sustainability of residential architecture in Nias.
