Abstract

The development of concrete technology in trials of adding mixed ingredients continues to be carried out to obtain the desired strength and quality of concrete. The clam shells contain pozzolanic chemical compounds, namely lime which is expected to be used as a substitute for fine aggregate in a mixture of concrete constituents. This research was conducted to determine the compressive strength of concrete by utilizing shell waste as a substitute for fine aggregate of 0%, 15% and 25% with aging observed at 7, 14 and 28 days. This research carried out several material tests such as sieving, aggregate specific gravity, moisture content, silt content, wear and tear, organic matter, slump test and concrete compressive strength test. Based on the results of the study, it was found that the optimum strength in mixed variations with shell waste as a substitute for 15% fine aggregate obtained a compressive strength value of 14.09 MPa at 14 days. From the results of the research conducted, it can be concluded that the use of shell waste as a substitute for fine aggregate is not recommended for the manufacture of concrete in the world of construction, because the strength value of the concrete obtained does not meet the requirements of Standard SNI 7656: 2012

Abstract

A slope is a surface that has a slope and forms a certain angle to the horizontal plane and is not protected. The slope and angle formed cause the slopes to have differences in surface height. Differences in slope surface height result in forces acting to push, and also forces in the soil acting to resist or resist, so that the position of the soil remains stable. The stability of a slope is expressed in the slope safety factor which is obtained or obtained by comparing the holding force and the pushing force. Based on topographic data of ground investigation drilling points on the Marangkayu Coal Port transportation route, Kutai Kartanegara Regency, it is known that there are several drilling points with soil conditions in the form of slopes or hills, so it is predicted that they could cause the potential for landslides because these points will become transportation routes for loading and unloading materials. coal. The aim of this research is to determine the slope safety figures, and to obtain a safe slope with the original slope conditions. The method used to analyze slope stability in this research uses Geostudio Slope Bishop method software. The results of the analysis of the original slope conditions at the OLC-FBH-03 and OLC-FBH-06 test points showed that the slope safety value was obtained with the result being that the slope condition was safe from landslides (FK>1.25). With this, it can be concluded that the Marangkayu Coal Harbor transportation route, Kutai Kartanegara Regency is safe from landslides.Keywords: Bishop Method, Geostudio Slope, Slope Stability, Slope Safety Value

Abstract

The construction industry in Indonesia is experiencing a significant increase, fueled by government infrastructure development. Concrete is the material of choice as it is easy to use, economical and strong. However, excessive sand mining has a negative impact on the environment, including land degradation and pollution. The increase in construction has led to an increase in construction waste, which, if managed properly, can be profitable. Effective waste management is crucial to address environmental concerns and the utilization of waste lightweight bricks offers a cost-effective and efficient solution. Studies related to the use of waste lightweight bricks as a partial replacement for sand in concrete are highly relevant. The results of compressive strength testing on normal concrete at the age of 28 days obtained based on data analysis and discussion that has been presented in the previous chapter regarding the use of waste lightweight brick powder fibers with variations of 0%, 5%, and 10% are 439 kN (f´c 24.85 Mpa), while variation 1 of 10% lightweight brick powder waste reaches 344 kN (f´c 19.48 Mpa), and variation 2 of 15% lightweight brick powder waste reaches 308 kN (f´c 17.44 Mpa).

Abstract

Roads play a crucial role in local economies, supporting the distribution of goods and the mobility of citizens, but are often damaged by heavy traffic loads, poor drainage and inadequate infrastructure. Asphalt pavement is a popular choice due to its durability and affordable construction costs. Building waste includes construction and demolition waste, containing recyclable to toxic materials. Management of this waste is effective to reduce costs and support industry sustainability, in Indonesia, granite stone waste is widely generated. Analysis of Marshall characteristics in AC-WC mixtures using granite stone powder as a substitute for filler with a variation of 30% resulted in a stability value of 2487 kg, a VMA value of 36.51%, a flow value of 3.35 mm, a VIM value of 26.19% and an MQ value of 742 kg/mm that meets specifications. The VFB test value of 28.27% does not meet the 2018 Bina Marga specifications. While the granite stone powder with a variation of 60% produces a stability value of 2568 kg, a VMA value of 37.31%, a flow value of 3.4 mm, a VIM value of 27.12% and an MQ value of 756 kg/mm that meets the specifications. Meanwhile, the VFB test value of 27.31% does not meet the 2018 Bina Marga specifications. The presentation results of the mix design on cement filler are hot bin I by 17%, hot bin II by 45%, hot bin III by 32%, cement filler 6%, asphalt 6%.

Abstract

Roads as transportation infrastructure play an important role in regional development and are used to transport basic necessities. Certain materials with specific durability are used for road construction, but damage can occur due to natural phenomena, excessive pressure, or material quality. This damage can endanger drivers and often causes accidents. The Bina Marga Road Maintenance Manual lists various types of damage, but this study only focuses on inspections to detect cracks. In Muara Angke, Central Jakarta, one ton of fish bone waste is produced every month from the fish cracker making process. This waste, which produces an unpleasant odor and contains BOD, COD, and TSS, pollutes the environment and makes the 400 m² industrial area unhealthy. Due to lack of skills and technology, local communities have not been able to process or utilize this fish bone waste effectively. The results of Marshall testing on the composition of AC-WC asphalt using fish bone powder waste with variations of fine aggregate substitution of 0%, 25%, and 50%, and asphalt content of 5%, 6%, and 7% did not meet the 2018 Bina Marga specifications for Stability, Void in Air, Marshall Quotient, and Void in Material values. The Marshall characteristics obtained from the mixture with fish bone powder waste are not comparable to the regular AC-WC mixture without waste. In addition, the VIM value for the mixture with 6% asphalt content and waste variations of 0%, 25%, and 50% also did not meet Bina Marga standards. However, all VMA and VFA levels still meet the asphalt and aggregate specification criteria according to Bina Marga 2018.
