Abstract

In a pipe network system, the design of the intake building plays an important role in determining the efficiency of water flow and distribution. Suboptimal designs can cause significant Pressure Losses, uneven flow distribution, and potential damage to infrastructure. This research aims to simulate and analyze the effect of design changes in the Jragung Dam intake building in Semarang Regency on its hydraulic performance. The Jragung Dam is one of the important infrastructures that supports water resource management in the region. In this research, WaterCad hydraulic simulation software was used to model water flow and hydraulic behavior in intake buildings. Hydraulic modeling based on current topographic, hydrological and engineering data of intake structures. Design changes are simulated to evaluate the differences in terms of flow capacity, pressure, and structural stability. The simulation results are then compared with the performance of the initial design with the design due to changes in the reservoir. The results of the research show that there is a change in the position of the reservoir with the minimum water level of the reservoir remaining at an elevation of +93,00, the outlet pressure for the raw water transmission pipe decreases to 1.97 mH2O, while the pressure in the other channels shows relatively small changes with a value of 33.48 respectively. mH2O, 11.34 mH2O, and 34.05 mH2O. These results indicate that the water pressure in the raw water transmission pipe is below the required standard (0.5-8 atm). To overcome energy losses in the raw water transmission line so that water can flow by gravity, the pipe diameter was changed from 900 mm to 1100 mm along 3,469 m. This modification produces an outlet pressure of 10.20 mH2O at the reservoir's minimum water level.

Abstract

No-Fines Concrete is a lighter type of porous concrete, which is made by removing sand from conventional concrete mixes. Fly Ash is a by-product waste from Steam Power Plants (PLTU) which use coal as fuel, in the form of fine, light, round particles and has pozzolanic properties. This research aims to evaluate the effect of using fly ash in No-Fines concrete in extreme environments, especially in peat swamp environments. The use of No-Fines concrete as a construction material is expected to reduce dependence on natural sand and utilize industrial waste such as fly ash. The peat swamp environment which has the characteristics of acidic and porous soil provides its own challenges in construction, so concrete with appropriate mechanical and physical properties is needed. The research results are expected to show that the addition of fly ash can improve the technical properties of concrete, especially in terms of strength and durability in peat swamp environments. It is hoped that it will contribute to developing environmentally friendly concrete materials and supporting the sustainability of construction in areas with extreme soil conditions. Apart from that, the use of fly ash as an additional material can help reduce industrial waste, while producing concrete that is economical and efficient to use.

Abstract

The use of concrete as a construction material has become an industry standard; however, excessive exploitation of natural sand has had a negative impact on the environment. No-fines concrete has emerged as an innovative alternative to reduce dependence on sand, offering advantages such as a porous structure that enhances permeability and thermal insulation. This study analyzes the use of Type F Fly Ash, a byproduct of coal combustion from the Asam-Asam Power Plant in South Kalimantan, as an additive in no-fines concrete to improve its mechanical properties and durability. Fly Ash acts as a pozzolanic material, which can partially replace cement and enhance compressive strength and resistance to extreme environmental conditions. The research was conducted through a literature review and cement and Fly Ash testing. The results indicate that the increase in Fly Ash content affects the cement hydration reaction, necessitating the selection of an appropriate dosage tailored to specific construction project needs. The incorporation of Type F Fly Ash enhances ecological sustainability and concrete efficiency, while simultaneously reducing industrial waste and the environmental impact of cement production. Therefore, no-fines concrete based on Fly Ash presents a sustainable solution for environmentally friendly infrastructure development.
