Abstract

Balikpapan City is a city that often experiences floods. One of the most frequently flooded locations is Gang Mufakat, which is located in Damai Village, South Balikpapan. This area is an area passed by the Ampal River Basin which is one of the causes of flooding besides the lack of vegetation as land cover in the settlement. This research aims to identify the management and control/control of floods in general. This is done to obtain information on several things that are considered important in management and to assess the understanding of the community and government regarding flood control/management. The research method used is a descriptive qualitative method. This research results from the community's understanding of floods and community actions in dealing with floods. Understanding of flooding in the form of causes of flooding, and the importance of the role of vegetation on land cover and the creation of infiltration wells. The recommendation for the government is to dredge sedimentation as well as deepen the Ampal watershed, and create a polder as a substitute for water catchment areas because there are many residential areas around the Ampal watershed which do not allow water to flow directly into the watershed. The recommendation for the community is to build an infiltration well in the Gang Mufakat.

Abstract

Jalan poros Samarinda – Bontang merupakan jalan nasional yang menghubungkan kota Samarinda dan kota Bontang. Longsoran yang terjadi di Sta.3+450 dapat membahayakan pengguna jalan. Diperlukan suatu penanganan untuk meningkatkan stabilitas lereng tersebut dengan melakukan analisa stabilitas lereng dengan menggunakan aplikasi plaxis 2D. Penelitian ini bertujuan untuk mengetahui nilai faktor keamanan stabilitas lereng setelah menggunakan perkuatan existing pasangan batu dan dinding penahan tanah bronjong dengan bore pile. Parameter tanah yang digunakan adalah model parameter Hardening Soil (HS) Undrained B. Tanah dibagi kedalam tiga lapisan dengan konsistensi lapisan lempung kelanauan bercampur laterit (0-2 m), lempung berpasir (2-6 m), dan batu lempung (6-16 m). Pada analisis stabilitas lereng menggunakan nilai beban lalu lintas sebesar 100 kN/m2 berpengaruh terhadap stabilitas lereng. Dari hasil analisis didapatkan nilai faktor keamanan stabilitas lereng dengan perkuatan existing pasangan batu sebesar 1,346 < 1,5 dimana nilai tersebut dikategorikan tidak aman. Hasil analisis stabilitas lereng dengan perkuatan dinding penahan tanah bronjong dan bore pile didapatkan nilai faktor keamanan sebesar 1,604 > 1,5 bahwa perkuatan stabilitas lereng tersebut dikategorikan aman karena memenuhi syarat angka keamanan sebesar 1,5 (Safety Factor > 1,5).
