Abstract

This study analyzes flood levels for the 2025 re-period in the Grand Madani Housing area, Gunung Gedangan Village, Mojokerto City. The study includes hydrological and hydraulic analysis using 10 years of rainfall data (2014 – 2023) from Mojosari Station, topographic analysis (Sungai Sadar watershed) and soil type (Sub – Sadar watershed), as well as drainage design based on the Rational method, HEC – RAS,. The rainfall distribution was tested using the Log Normal, Pearson Log Type III, and Gumbel methods, and tested for compatibility with the chi-square test. The results showed that the distribution of Pearson Log Type III was most consistent with the data (kurtosis statistical value γk = 3.247). The planned rainfall for T = 2 years is 165.7 mm, and T = 100 years is 329.3 mm (Normal Log), which is used to calculate the rainfall intensity (Talbot, Ishiguro, Sherman method) and the planned flood discharge by the Rational method (Q = 0.278· C·Cs· I·A). The planned flood discharge obtained is 9,399 m³/s, greater than the existing channel capacity of 8,053 m³/s, so channel replanning is required. Hydraulic simulations using HEC – RAS 5.1 showed that the proposed drainage design (30 cm × 40 cm cover box) was able to accommodate the design rainfall (25-year re-period) without overflow. The study contributes to residential flood mitigation through the calculation of adequate plan discharge and drainage design recommendations, as well as the use of hydrodynamic models to ensure the performance of the channel to the standard.

Abstract

The architecture of the archipelago is rich in cultural values that have been inherited from generation to generation. By adopting local architectural elements into modern designs, we help preserve and preserve Indonesia's cultural heritage. Respect for Local Wisdom: Traditional architecture is designed based on centuries of experience that takes into account the local environmental and cultural conditions. Proud of the Nation's Identity: Showing the architecture of the archipelago in the midst of the era of globalization is a form of appreciation for local wealth that is often forgotten. The typical architecture of the archipelago is rooted in the principle of respecting nature and contextualizing it with the surrounding environment. Traditional houses are often in harmony with the topography, vegetation, and surrounding natural conditions. In the modern context, this can mean maintaining environmental sustainability and creating harmony with nature. Conceptualizing a modern residential house with typical archipelago architecture is not only about beauty, but also about functionality, cultural preservation, and responsibility for the environment. This approach offers a blend of modern conveniences and local wisdom that has proven effective over the centuries. The concept of a modern residence with traditional Balinese architecture combines contemporary elements with local Balinese wisdom, creating a harmonious residential atmosphere between tradition and modernity. The research method used to examine the concept of traditional Balinese architecture requires a comprehensive approach, considering that this architecture is very rich in cultural, spiritual, social, and environmental values. The results of this study are: The concept of using guardrails and vegetation that is quite dense in terms of function to reduce the source of noise from outside the site and inside the site. The concept of building placement is in or away from the road. ; The use of vegetation can filter the air to cool so that it can affect the air conditioning in the building. ; Use of voids in Buildings. ; The Indonesian wind moves from the Southeast to the Northwest. ; Maximizing natural ventilation without compromising comfort in the building. ; The addition of a small canopy or tritisan as a barrier to sunlight that directly enters the building with later added curtains inside to reduce heat. ; The concept of circulation in this building is the main entrance which functions as an in-out vehicle. ; Drainage Creation in the house entrance area to accelerate the descent of rainwater. ; Rainwater reservoir by directing towards the front sewer. ; The concept of parking this building will be made one because it is considered for a private house.

Abstract

The increasing need for housing as the population grows is a challenge for sustainable environmental management. Housing is an important element of urban ecosystems that affect quality of life. Kamajaya housing in Singosari District is designed for the needs of modern housing with environmental aspects, but there is still a need for deeper analysis regarding the application of sustainability principles. Environmental sustainability in housing includes energy use, water and waste management, green space, and climate change adaptation. Sustainable housing improves air quality, resident health, and comfort. This study aims to evaluate the sustainability of Kamajaya Housing to provide recommendations for improving environmental quality and supporting sustainable housing policies. Suitability of Space Utilization Activities (KKPR) is a tool in spatial planning to ensure optimal and sustainable land use by considering environmental, social, and economic aspects. The Ministry of Fisheries and Fisheries prevents land conflicts, preserves the environment, and encourages sustainable economic growth. The implementation of the KKPR requires adequate data, conflict of interest management, and strong analytical capacity. The results of the study show that the Building Boundary Line (GSB) is decided to have a minimum distance of GSB of 5 m + 5.5 m. The distance of 11 m for this measurement is in accordance with the IKKPR Decree, namely the minimum distance of GSB 5 m + 5.5 m measured from the outermost side of a building mass to the Road Axle which is the measurement reference. Kamajaya Housing occupies 58.02% of the Land Area so that the KDB is less than 70% of the Land Area. KDH Residential Buildings less than 10 % Land area with RTH Composition: Garden: 132 m2. Net Needs for Residential Buildings, then the amount of water needs has been able to be met by the Clean Water Source by the PDAM network, which is 125 Liters / Minute. Referring to SNI 03 – 7065 : 2005 Plumbing System Planning Procedures. Consumption of Residential Houses with Occupants amounting to 4 people with effective activities per day is 8 hours, the waste of dirty water is 65 liters. Referring to SNI 03 – 7065 : 2005 Plumbing System Planning Procedures. For rainfall figures are = 8 Liters / Minute
