Abstract

The Depok Jaya Market, located in the city of Depok, has a relatively high level of activity. The travel attraction in Depok Jaya Market in this study was conducted through a survey method using questionnaires to determine socio-economic characteristics. From the research results, there is a high level of activity in Depok Jaya Market, a shopping center with a building area of ± 2,332 m2, capable of attracting 700 visitors per day. The obtained data were processed using SPSS software by conducting correlation tests, and then regression analysis was performed to obtain equation models. From the regression analysis results, a multiple regression model was found consisting of Y1 = 16.667 + 0.006 (X5) with a coefficient of determination (R2) = 0.758, Y2 = 10,000 + 0.003 (X5) with a coefficient of determination (R2) = 0.273. This model explains that the independent variable influencing the magnitude of vehicle travel attraction is the parking area (X5). Then, from the primary data, a multiple regression model was obtained consisting of: Y1 = 0.437 + 0.244 (X5) + 0.155 (X6) + 0.531 (X11), which means Cleanliness (X5), Price (X6), and Length of Visit (X11) collectively influence 40.9% on Last Visit; Y3 = 0.437 + 0.244 (X5) + 0.155 (X6) + 0.531 (X11), which means Cleanliness (X5), Price (X6), and Length of Visit (X11) collectively influence 40.9% on Visit Intensity (Y2); Y4 = 1.225 + 0.581 (X11), meaning that the last visit influences 33% on the data for the length of visit.

Abstract

National road projects usually use flexible pavement types because they can adapt to diverse soil conditions and are comfortable to use. In the construction project for JLS Lot 1A Brumbun – P. Sine, there is soft soil condition at STA 4+050 with low CBR value, while at STA 5+315, the CBR is high due to excavation of soft rock. However, throughout the planned road, only one thickness design of the pavement is used. The location also has subsoil that often experiences water seepage, causing saturation and potentially leading to consolidation and ground settlement. Therefore, a study was designed to analyze the effect of variations in CBR values on pavement thickness and provide recommendations for pavement thickness that can prevent ground settlement due to saturated soil, considering the thickness of the layers based on field CBR values using MDPJ 2017, Pt T-01-2002-B, and MDPJ 2024. The data collection method used secondary data from the project and conducted a literature study, resulting in the finding that the CBR of the subgrade can affect the thickness of the pavement in terms of the foundation layer thickness. Recommendations for the thickness of the flexible pavement layers using the MDPJ 2024 method are 4 cm for AC-WC, 14.5 cm for AC-BC, 20 cm for Class A LPA, 15 cm for Class B LPA, and a cement stabilization thickness of 20 cm for CBR <10% and a stabilization thickness of 15 cm for CBR >10%
