Abstract

Due to urbanization, informal settlements have been portrayed as a form of adaptation in managing a community’slimitations. Using informal settlements along the railway road in Cimahi City as a case study and qualitative method, this study aims to see how the community conducts adaptation and shapes the surrounding environment. The study found two types of adaptation, adjustment and reaction, as a response to rail noises, limited space, and accident-prone problems. In addition to the adaptation, there is a co-production in producing services to assure the community’s safety since they live along the railway road. The findings revealed that the absence of government in guaranteeing citizens’ rights has enforced community creates a system that increases community resilience.

Abstract

The California Bearing Ratio (CBR) value has become the standard for determining the bearing capacity of soil,especially subgrade, in highway construction. Usually expressed as a percentage, the CBR figure can be obtained in the laboratory (CBR Lab) or the field through the Dynamic Cone Penetrometer (DCP) test. This study examines the relationship between the Laboratory CBR and the Field CBR from the results of the DCP test on 12 soil samples obtained at the research location on the Mirit - Tambakmulyo Road Section (Kebumen Regency, Central Java). The samples were then analyzed using a mathematical formula to obtain a regression equation and correlation value. Based on the AASHTO method, the soil at the research location is classified as A-6 soil type, namely clay soil, with a general assessment of moderate to poor subgrade. For the USCS method, the most dominant soil classification is CL: non-organic clay with low to moderate plasticity, gravelly clay, sandy clay, and dusty clay. The Laboratory CBR value was obtained from 5.59% to 7.90%. Two samples have a CBR Value <6.00%, namely Sample 10 and Sample 11. Meanwhile, for the CBR value from the DCP test in the field, the CBR range is 5.11% to 12.96%. There is only one sample with a CBR Value <6.00%, namely sample 5, which has a CBR figure of 5.11%. The CBR value of 6.00% is the minimum subgrade requirement in the Manual Desain Perkerasan 2024 released by the Indonesian Directorate General of Highways. From the results of the regression calculation and correlation of Field CBR to Laboratory CBR, the equation y = -0.0614x + 7.1492 is obtained with a correlation coefficient (r) = -0.1862. The correlation pattern obtained is a weak negative direct correlation. The coefficient of determination (R2) = 0.035 indicates that the accuracy of the regression model is quite good. This study proves that the correlation between Field CBR value and Laboratory CBR is weak and not statistically significant.

Abstract

In the present era, many individuals rely on public transportation to meet their daily needs, particularly in Jakarta, Indonesia. Various options, such as trains and buses, serve as the primary choices for public transportation. This study, which focuses on the Gelora Bung Karno Stadium (GBK) area, explores the implementation of the Transit Oriented Development (TOD) concept. TOD is a planning strategy that aims to create compact, mixed-use communities centered around transit stations, with the intention to enhance economic growth, facilitate access to integrated public transportation, and reduce reliance on private vehicles to mitigate air pollution levels in the city. The research findings indicate that applying this concept can positively impact economic development and the efficiency of public transportation while concurrently fostering a cleaner and more sustainable environment for urban communities. This study is pertinent to current dynamics, where an increasing number of individuals are opting for public transportation as a primary solution to address urban mobility challenges.

Abstract

Accumulating coal combustion waste will negatively affect the neighborhood. Over time, more waste will be generated, which will take time. Processing methods are needed to reduce the increasing amount of coal waste. One processing method is to use ash and bottom ash as a mixture in paving. The study used paving blocks as a control sample for one cement : 3 sand. Fly ash addition variation consists of 0%, 10%, 20%, and 30% of the cement weight. The compressive strength test results at 28 days and 60 days of control paving blocks with a standard mixture were 17.8 MPa and 24 MPa. The compressive strength results from 0% variations are 10.9 MPa and 15.6 MPa. The 10% variation has a compressive strength of 10.5 MPa and 13.6 MPa. The 20% variation has a compressive strength of 10.25 MPa and 14.5 MPa. The variation is 30%, with compressive strength of 11.5 MPa and 14.86 MPa.

Abstract

This study aims to determine how wide the catchment area is on the Melayu and Jambi rivers, how much the planned flood discharge is at a return period of 2, 5, 10, 25, and 50 years with the Nakayasu Synthetic Unit Hydrograph (SUH) Analyze the water level of these rivers downstream at the planned flood discharge conditions due to backwater from the Jambi river. This also plans the cross-sectional area and length of the Jambi River as a new channel to the Batanghari River using the HECRAS model. The result shows that the Melayu River can still serve a water level of 10 for a 10-year return period and the Jambi River with a water level of 25 for a 25-year return period. However, there is a need for normalization of both rivers and disposal in a large basin located 2 km from the Melayu River. The length of the new channel section as a connection to the Batanghari River as a final water channel is 1,060 meters long, 5 meters wide at the top, 3 meters wide at the bottom of the river, with a depth of 5 m, with a channel embankment using an earthen wall.

Abstract

The current supply chain is not just an activity but has moved towards effectiveness and efficiency of performance called the sustainable supply chain. With the threat of inefficiency, construction service business actors are expected to be able to manage the supply chain of their respective businesses. Specifically for the construction industry in Tasikmalaya City to manage the construction supply chain, this study was conducted with the title Identification of Sustainable Construction Supply Chain Patterns in Projects in Tasikmalaya City. This study aims to identify the supply chain system patterns of construction service companies, especially contractors, and what development patterns can be carried out by construction service companies to increase the competitiveness of construction service businesses in Indonesia through literature reviews and case studies on contractor companies in Tasikmalaya. This research method uses descriptive microanalysis from the results of semi-structured interviews. Data collection will be collected by direct interviews with construction project owners or managers in their respective projects. Based on the results of descriptive analysis of the information obtained, a general model is compiled that describes how the supply chain system pattern is carried out. The preparation of the supply chain pattern resulting from the identification will refer to the pattern developed by Susilawati in previous research, where the supply chain pattern has a relationship from the owner to the lowest subcontractor. This study identified three supply chain patterns where the pattern has a maximum of 4 tiers, and the selection of the supply chain pattern is based on the type of project being worked on and the company's ability to manage the project. The critical points for building an integrated supply chain are knowing the value desired by the client, building long-term relationships with suppliers, integrating activities, collaborating to manage costs, developing continuous improvement, and mobilizing and developing human resources.

Abstract

Wearing Course Lataston (HRS-WC) is a type of flexible pavement with durable and good durability and flexibility. The constituent materials of HRS-WC asphalt consist of aggregate, asphalt, and filler. Bentonite powder is an active chemical filler material with superior swelling ability, ion exchange properties, and large surface area. It quickly absorbs water to form a thick suspension. This research aims to determine and determine the Optimum Asphalt Content (OAC), optimum filler content, comparison of the percentage value of increase or decrease in Marshall test parameters, and the effect of adding bentonite powder filler to HRS-WC Asphalt on asphalt performance according to the General Specifications for Bina Marga Year 2018 Revision 2. Based on the research results on Marshall characteristics, the KAO value was obtained at 7.5%, and the optimum filler content value was 1.90%. The addition of bentonite filler shows changes in the characteristics of HRS-WC asphalt, namely an increase in stability, Marshall Quotient, and VFA, as well as a decrease in flow, VIM, and VMA. So, the effect of adding bentonite filler to HRS-WC asphalt can increase density, reduce the number of voids, fill voids between aggregates, and be able to bind asphalt to the asphalt mixture. However, the excessive addition of bentonite powder as a filler can reduce the flow value and make the asphalt mixture harder and stiffer.
