Abstract

Ruas Jalan Airmadidi – Kairagi merupakan jalan arteri primer dan salah satu prasarana transportasi yang memegang peran penting dalam hal mendukung pertumbuhan guna meningkatkan kegiatan ekonomi, sosial, dan budaya. Tujuan penelitian ini adalah untuk menganalisis tingkat kelayakan fungsi jalan serta perbaikan yang diperlukan agar jalan menjadi laik menurut Uji Laik Fungsi Jalan (ULFJ) berdasarkan Peraturan Menteri PU Nomor 11/PRT/M/2010. Uji laik fungsi jalan adalah kondisi suatu ruas jalan yang memenuhi persyaratan teknis kelaikan jalan untuk memberikan keselamatan bagi penggunanya, dan persyaratan administratif yang memberikan kepastian hukum bagi penyelenggara jalan dan pengguna jalan, sehingga jalan tersebut dapat dioperasikan untuk umum. Analisis uji laik fungsi teknis jalan dilakukan dengan mengevaluasi dan monitoring kondisi lapangan secara visual terhadap standar teknis untuk setiap komponen teknis,  meliputi: teknis geometrik jalan, teknis struktur perkerasan jalan, teknis struktur bangunan pelengkap jalan, teknis pemanfaatan ruang bagian-bagian jalan, teknis penyelenggaraan manajemen dan rekayasa lalu lintas, dan teknis perlengkapan jalan. Hasil dari penelitian ini menunjukkan bahwa pada ruas jalan Airmadidi – Kairagi untuk STA 0+000 – STA 11+968 dikategorikan Laik Fungsi Bersyarat (LS), yang artinya jalan tersebut memenuhi sebagian persyaratan teknis laik fungsi jalan namun masih mampu memberikan keselamatan bagi pengguna jalan sehingga laik dioperasikan untuk umum dengan syarat harus dilakukan  Perbaikan teknis pada ruas jalan tersebut, seperti perbaikan serta pemeliharaan rutin terhadap setiap komponen pengujian yang dikategorikan Laik Fungsi Bersyarat (LS). Kata kunci: Uji Laik Fungsi, Perbaikan, Standar Teknis, Ruas Jalan Airmadidi – Kairagi

Abstract

In 2020, flooding occurred in the village of Molibagu, causing damage and losses for the residents who live and work around the Molibagu River. One of the causes of this flood was heavy rainfall, which triggered an increase in the flow discharge of the Molibagu River. Therefore, an analysis of the flood discharge and water level in the Molibagu River is needed to minimize the potential risk of flooding and to determine effective control strategies based on developed scenarios. The objective of this research was to identify effective scenarios from several alternatives, including normalization and the addition of embankments on the left and right sides of the river, to control flooding. The Molibagu Watershed has an area of 38.7 km². Secondary data in the form of rainfall data was obtained from the Sulawesi I River Basin Office (BWSS-I). The rainfall stations ARR-MRG Kosinggolan Matayangan and MRG Bolangaso Molibagu are the sources of maximum daily rainfall data, which will be analyzed over the period from 2008 to 2022. To obtain the parameters needed to determine the peak discharge of 17.5 m³/s, the HEC-HMS software is used. After obtaining the calibrated parameters, the analysis will continue to determine the design flood discharge for various return periods using the HEC-HMS software. The design flood discharge for the return periods will then be input into the HEC-RAS software to obtain the inundation area and water surface elevation of the Molibagu River. As a form of flood control, three flood control scenarios are applied: normalization, embankments, and a combination of normalization and embankments, using RAS Mapper to model and show the extent of the inundated areas. Based on the simulation results obtained, the second scenario, which involves handling with normalization at the same elevation and based on existing flood discharge, is more effective in reducing water level height and mitigating flood overflow better than handling with levees. However, in this scenario, the river cross-section is not able to reduce the flood discharge at the 50 and 100 year return periods, so a combination of the first and second scenarios is needed to reduce the flood and there is no more inundation.
