Abstract

Soil conditions with weak zone points can cause damage to road structures such asland subsidence. Geoelectric surveys can identify subsurface structures based onvariations in rock resistivity. Road infrastructure crash due to weak zones of soilbearing capacity can be identified by geoelectric surveys and geotechnical tests assupporting analysis. Based on the master plan of Politani Samarinda 2025-2029 inthe southern area, a ring road of ± 1.5 km will be built, so geoelectric andgeotechnical support data are first needed as a basis for road planning. The mainobjective of this study is to mapping subsurface structure and identify the stability ofthe strong and weak zones of the soil in the planned area of the ring roadconstruction. The geoelectric resistivity survey uses the Wenner Schlumbergerconfiguration with 2 longitudinal tracks of ± 100 m per track with a spacing (a) of 5m which can identify the distribution of subsurface resistivity values laterallymapping.The resistivity value obtained from 2D geoelectric inversion is the lowestvalue of 2.62 ohm.m which is suspected as clay, medium 78.5 ohm.m which issuspected as sand, and the highest 7716 ohm.m which is suspected as sandstoneand used as a reference in the strong zone of the road building foundation.Furthermore, the USCS classification geotechnical test at 2 track points resulted insand (SM) and silt clay (MH) soil types based on mechanical laboratory tests. Theresults of the identification of geoelectric surveys and geotechnical tests have asignificant correlation with road construction that has a potential strong zonebearing capacity because the top soil is in the form of silt, clay, sand which isunderneath in the form of sandstone which is strong enough to withstand the load ofroad construction.

Abstract

The arrangement of slum areas is one of the important strategies in realizing a livable, healthy, and sustainable residential environment. However, after the arrangement, there is often a vacancy in social functions in the area due to the suboptimal utilization of public spaces. This study aims to formulate a model for the development of inclusive and adaptive public spaces in large-scale post-slum arrangement areas, using case studies in the Allepolea and Maccini Baji areas, Lau District, Maros Regency, which have a total slum area of 17.23 hectares. The research method used is a qualitative-descriptive approach with data collection techniques including field observation, in-depth interviews, questionnaire surveys, and a review of planning documents (RTRW 2022–2042). The results show that there is an urgent need for public spaces that can accommodate social activities, informal economic activities, and interactions between residents. Based on the analysis, an alternative model for public spaces based on local needs is formulated, which includes functional, ecological, and socio-cultural aspects. This model is expected to serve as a reference for planning public spaces in residential areas that have been arranged, both in Maros and in other similar areas.
