Abstract

Research was carried out to see the potential for flooding through Computational Fluid Dynamic simulations, namely a set of methodologies that allow computers to provide numerical simulations of fluid flow. The entire system is transformed into virtual form, and can be visualized via computer. Components in fluid dynamic computing include selection of mathematical models, discretization, numerical analysis schemes, numerical solutions and representation of processes numerically and graphically. Flood mapping can provide information about which areas need special attention so that it can be used as a reference in making policies related to flood management and can be used to increase wider public awareness regarding floods. The HEC-RAS permanent flow module is able to take into account the influence of various flow obstacles, such as bridges, culverts, bends, or obstacles on riverbanks. The permanent flow module is designed for use in riverbank management environments and the determination of flood risk insurance regarding the determination of riverbanks and floodplains. The permanent flow module can also be used to estimate changes in water level due to channel improvements or embankment construction. HEC-RAS permanent flow special module features include double plan analysis, double profile calculation, double culvert or gate analysis, flow optimization, and stable channel design and analysis. From the simulation results and depth classification, information on the area of inundation and areas prone to flood inundation on the Lepo-Lepo River is 29.34 Ha.

Abstract

The stability of landfill is a crucial aspect of waste management. Numerous factors influence the stability of landfill, one of which is the alteration of the mechanical properties of the waste material. This research aims to analyze landfill stability by considering the effects of changes in the mechanical properties of waste material. A construction stage analysis was conducted to model the process of altering the mechanical properties of waste material. The analysis was divided into 13 stages corresponding to the number of landfill steps. The initial five stages were modeled as waste with an age of < 5 years, stages 6-10 were modeled as waste with an age of 5-10 years, and the last three stages were modeled as waste with an age of > 10 years. Stability analysis using the finite element method was conducted using the concept of shear strength reduction. The analysis results indicated changes in the landfill's safety factor throughout its operational period. Stages 1-5 experienced changes in the safety factor, although these changes were not significant. Stages 6-10 witnessed a considerable decrease in the safety factor before experiencing an increase in stage 11, followed by a continuous decline until the end of stage 13. Despite changes in the safety factor during the operational process, the overall safety factor values obtained still met the minimum safety factor criteria required.

Abstract

Concrete is a construction material consisting of cement, fine aggregate, coarse aggregate which is mixed and added with sufficient water to form a dough which then hardens into hard concrete. This study aims to determine technical feasibility, the cost and the difference to the unit price based on the 2021 Regent's Regulation and to analyze the unit cost of construction of local Wakatobi materials and materials outside Wakatobi based on Analisa Harga Satuan Pekerjaan (AHSP). The method used in this study to determine the compressive strength of concrete refers to SNI 1974; 2011 and carried out observations and measurements in the laboratory with 60 specimens in the form of a cylinder with a diameter of 10 cm and a height of 20 cm with a concrete age of 28 days for each mixture variation. The results of the study obtained the compressive strength of aggregate variations on 100% Moramo coarse aggregate on crushed stone and sand with several variations. Comparison of the unit price of the Wakatobi local fine aggregate material with the outer Wakatobi fine aggregate material is 32.40% higher, the Wakatobi local coarse aggregate material unit price and the outer Wakatobi coarse aggregate material unit price is 52.17% higher. The construction unit cost for making 1 m3 of concrete using local Wakatobi materials is Rp. 1,916,756, and the construction unit cost for making 1m3 of concrete using non-wakatobi materials is Rp. 2,678,889. With a large construction unit, making 1m3 of concrete using external Wakatobi materials is 28.45% higher.

Abstract

The Langara Coastal area is the economic center area of the capital city of Konawe Islands Regency. However, the provision of clean water as a basic need is still not fulfilled, this is because the source of clean water in the Langara Coastal Area currently still depends on Community Self-Help, as a result, water distribution is carried out in shifts. This research aims to determine air needs, the condition of the existing distribution network, and optimize the clean water distribution system. Air requirements are calculated using an analysis of population projections for 15 years. Analysis of pipe hydraulics using EPANET 2.2 Software, and air flow by gravity using PVC pipes. The analysis results show that the population in 2036 will be 1816 people with peak hour water demand of 4.13 l/sec. The condition of the existing distribution network shows that all Junctions have an average pressure of 9 atm. Meanwhile, the pipe with the highest speed at P3 is 0.47 m/s and the speed at P15 is 0.04 m/s, indicating that the existing conditions do not meet the technical criteria of Minister of PUPR Regulation No. 27/PRT/M/2016. So to increase the flow speed it is necessary to change the pipe dimensions at several points. In peak hour optimization simulations, the maximum speed occurs in pipes P2, P3, P4, and P10, namely 2.61 m/s, while the lowest speed occurs in pipe P21, namely 0.30 m/s. The results of this optimization are by the speed criteria in Minister of PUPR Regulation No.27/PRT/M/2016

Abstract

Tobuuha Village, Puuwatu District, Kendari City was previously a green open area which was naturally used for water absorption. However, this area has now changed its function to become a densely populated residential area, resulting in a significant reduction in water absorption. As a result, when it rains, surface flow becomes greater and causes puddles downstream. The aim of this research is to model the Tobuuha retention pond using the SWMM application for environmental changes that occur. Primary data collection was carried out by observing existing conditions and measuring the dimensions of channels and ponds around the retention pond. Meanwhile, secondary data was obtained from related agencies. The results of the research show that the flood discharge that will enter the retention pond is Q5 = 0.559 m3/second with the volume of water that enters and must be accommodated in the retention pond of 4577.0934 m3, while the existing capacity of the retention pond is 6978.44 m3, so it is considered still able to reduce flooding downstream of the pond. Therefore, the city government's plan to expand and increase the depth of the pool is not necessary because it will reduce the open space around the pool. Handling potential flooding and inundation around the location can be done by adjusting the sliding door openings and modifying several channels, namely channels J51-J52, M62-M63, N71-N106, and U97-U101. The SWMM simulation results for the proposed solution show that the retention pond is effective enough to prevent flooding in the surrounding area
