Abstract

East Kalimantan's proposed development as Indonesia's New Capital City must, of course, need a lot of local support. There is no doubt that the effects of Indonesia's New Capital construction vary by region, with those closest to them feeling the effects the most. A single one of them is Balikpapan. The construction of nearby local roads is influenced directly or indirectly by Indonesia's New Capital, both as it is now and as it is planned. This study talks about how Balikpapan is growing to support Indonesia's new capital. The reliability test produced a determinant coefficient (R-Squared) of 0,7569 for the model, which was developed using macro simulation software (PTV Visum). To forecast how the road network will perform once Indonesia's new capital city is operational, modelling is still being done. Twelve recommendations were made as a result, and they will be put into action between 2024 and 2039. The outcome indicated that the vehicle-hour dropped between 2024 and 2039. ABSTRAK Rencana pembangunan Ibu Kota Baru Indonesia di Kalimantan Timur, tentunya membutuhkan dukungan yang cukup besar dari daerah sekitarnya. Dampak pembangunan Ibu Kota Baru Indonesia tentu berbeda di setiap daerah, dan yang merasakan dampak paling besar di daerah terdekat. Salah satunya adalah Kota Balikpapan. Ibukota Baru Indonesia, baik yang sudah ada maupun yang direncanakan, menyebabkan berkembangnya jalan-jalan lokal di sekitarnya secara langsung maupun tidak langsung. Penelitian ini membahas tentang perkembangan kota Balikpapan untuk mendukung Ibu Kota Baru Indonesia. Model dibuat dalam software simulasi makro (PTV Visum) dan uji reliabilitas menghasilkan koefisien determinan (R-Squared) sebesar 0,7569. Tahap pemodelan dilanjutkan untuk memprediksi kinerja jaringan jalan setelah Ibu Kota Baru Indonesia beroperasi. Hasilnya memberikan 12 rekomendasi yang akan dilaksanakan dari tahun 2024 - 2039. Hasil penelitian menunjukkan bahwa vehicle-hour mengalami penurunan dari tahun 2024-2039.

Abstract

This study examined the presence of underground water channels under the Makassar - Pare-pare railway line KM 68+450 – KM 68+750 and the design concept for the technical solution. The potential for underground water channels was identified during construction, based on community information, the location's morphological phenomena, and  geological conditions whose base rock was the limestone formation. The problems can cause instability of the railway line, resulting in unsafe train travel. One of the characteristics of limestone rock conditions is its hollow shape, like a cave that can become underground water flow. It was a case study whose solution was based on data obtained from geotechnical investigations. Boring testing can only provide information on soil layers at the test point and cannot describe soil stratigraphy section, including underground water channel.  Combination  ERT and Boring tests were carried out to examine the presence of underground water channels. This study was conducted in three stages: initial identification, advanced identification, and design concept of Technical Solution. In these three stages, data collection and analysis were carried out. The results of the study indicated that ERT tests could provide a picture of the subsurface to shallow bedrock, thus facilitating the justification of geotechnical design. From the analysis, it was concluded that no channel cavities, such as caves, that function as underground water channels. The existing water flow was estimated to be a confining aquifer where water flows due to the height difference in the surrounding morphological conditions through the media of the broken limestone water shaft. It was confirmed with the results of Boring and ERT tests. The proposed technical solution concept was strengthening the Dolken embankment structure and geogrid, combined with a subdrain layer. The technical solution was prepared based on the results of research on construction contract data and project resource readiness.
