Abstract

Almost every year the city of Tarakan experiences problems regarding standing water during the rainy season, especially in the West Tarakan sub-district which is the center of Tarakan City. This puddle not only submerged settlements and offices but also shops and road access which caused considerable economic losses. This can be overcome by analyzing the risk of waterlogging where each area has a different level of vulnerability. The purpose of this study is to determine high, medium, and low risk areas for standing water in the Drainage Area of West Tarakan District, Tarakan City. The research implementation method includes data collection (institutional and field surveys), analyzing the index of vulnerability, vulnerability and capacity and analyzing the flood risk map. The index analysis is carried out through simulated parameter score analysis. Based on the results of the analysis of the research data, it can be concluded that the water inundation risk index in the West Tarakan District is as follows, the sub-districts that are on the highest risk index are Karang Anyar sub-district, then Karang Rejo village, kelurahan Karang balik and Kelurahan Karang Newar Pantai Nerda is at index 2 or is at a moderate risk index, then the kelurahan that has the lowest risk index is Hope Reef with a risk index of 1

Abstract

SWMM is a rain-runoff simulation model that is used to simulate the quantity and quality of runoff from urban areas. Based on the evaluation using SWMM software at Pesona Citra Cemerlang 2 Housing, it was found that the drainage system in the long sections JU29-O5, JU4-O8, and JU5-O8 could not accommodate rainwater runoff. This is influenced by the dimensions of the drainage channel which cannot accommodate the existing water runoff and thick sediment deposits that cover the drainage channel so that the capacity is reduced, consequently if it rains it will cause puddles of water at several points in Tarakan City. So to overcome the puddle, it is necessary to change the dimensions of the channel and routinely dredge the sediment deposits that cover the drainage channel

Abstract

The need for water will continue to increase, while the availability of water is limited; therefore, the provision of water must be pursued both by the government and independently. Rawasari Reservoir is one of the reservoirs in Tarakan City with a relatively stable volume and an effective storage capacity of 112,982 m3. The water source of Rawasari Reservoir comes from a channel that is a tributary experiencing sedimentation due to the sedimentation process. Based on this, the research team was interested in calculating sediment transport in the conveyance channel of Rawasari Reservoir using both empirical methods and the HEC-RAS 6.0 software. The methods used in this research are empirical using the Engelund Hansen and Laursen equations, as well as the use of HEC-RAS 6.0 software. Based on the analysis results, the sediment transport rate in the conveyance channel of Rawasari Reservoir calculated using the empirical method at STA 0+025 is 1,6427 x 10-9 ton/s for the Engelund Hansen method and 2,9898 x 10-9 ton/s for the Laursen method. The simulation of sediment transport in the bed of the conveyance channel of Rawasari Reservoir using the HEC-RAS 6.0 sediment transport model at STA 0+025 is 4,61x10-5 ton/s with the Engelund Hansen sediment transport function and 0,000306 ton/s using the Laursen sediment transport function.

ABSTRACT: Tarakan City has a large problem of land conversion which results in a decrease in the infiltration area. Jalan Pattimura, Pamusian Kelurahan is one of the points in Central Tarakan District that has the potential for flooding due to high rainfall intensity. The purpose of this study is to calculate the flood discharge Q25, Q50 and Q100 and to evaluate the channel capacity against the flood discharge. The method used to calculate the discharge is the modified rational method. The design flood discharge with a return period of 25, 50 and 100 years in the catchment area of drainage channel 1 is calculated using the modified rational method is 0,112 m3/sec for Q25, 0,115 m3/sec for Q50 and 0,117 m3/sec for Q100. Furthermore, the design flood discharge in the catchment area of drainage channel 2 is calculated using the modified rational method is 0,111 m3/sec for Q25, 0,113 m3/sec for Q50 and 0,115 m3/sec for Q100. Based on the evaluation of the existing channel conditions of Jalan Pattimura, Pamusian Kelurahan, Tarakan City, it was obtained that the existing channel capacity with the existing channel height is able to pass a discharge of 0,366 m3/sec for Drainage Channel 1 and 0,312 m3/sec for Drainage Channel 2 so it can be concluded that the current channel is still able to pass the discharge Q25, Q50 and Q100 years.

Abstract

Abstrak Banjir akibat air pasang atau banjir rob merupakan salah satu bencana yang sering terjadi di wilayah pesisir yang menggenangi bagian daratan di wilayah pesisir yang memiliki ketinggian (elevasi) lebih rendah dari muka air laut pasang tinggi. Kejadian banjir akibat pasang ini sudah memasuki area pemukiman penduduk di beberapa titik lokasi di Tarakan termasuk di sekitar kanal bandara Kota Tarakan. Berdasarkan pengamatan lapangan terdapat pemukiman warga di sisi kiri aliran kanal bandara Kota Tarakan, sehingga genangan mengganggu aktivitas warga. Berdasarkan permasalahan tersebut penelitian ini bertujuan untuk mengetahui tinggi muka air pada penampang kanal bandara Kota Tarakan akibat pasang surut dan banjir rancangan periode ulang 5 dan 10 tahunan. Metode yang digunakan untuk menganalisis tinggi muka air kanal bandara Kota Tarakan yakni menggunakan software HEC-RAS. Berdasarkan hasil analisis tinggi muka air menggunakan HEC-RAS diperoleh tinggi muka air penampang kanal bandara Kota Tarakan akibat banjir 5 tahunan dan 10 tahunan yang terjadi bersamaan dengan pasang tertinggi (HHWL) diperoleh tinggi muka air pada penampang sta 0+100 - 1+000 sebesar 3,8 m dan penampang 1+100 - 1+500 sebesar 3,81 m. Dari hasil penelitian ini maka disarankan pemerintah membangun pengendalian banjir dengan membuat tanggul dengan elevasi +4,5 m dari datum muka air terendah (LLWL). Kata kunci: Banjir rancangan, HEC-RAS, pasang surut, tinggi muka air,  Abstract Floods caused by high tides or tidal floods are one of the disasters that often occur in coastal areas that inundate the mainland areas in coastal areas that have lower elevations than the high tide sea level. The occurrence of tidal floods has entered residential areas at several locations in Tarakan, including around the Tarakan City airport canal. Based on field observations, there are residential areas on the left side of the Tarakan City airport canal, so the inundation disturbs the activities of the residents. Based on this problem, this study aims to determine the water level in the section of the Tarakan City airport canal due to tidal floods and floods with a 5-year and 10-year return period. The method used to analyze the water level of the Tarakan City airport canal is by using the HEC-RAS software. Based on the analysis results of the water level using HEC-RAS, the water level in the Tarakan City airport canal section due to a 5-year and 10-year flood that occurs simultaneously with the highest tide (HHWL) was obtained the water level at the sta 0+100 - 1+000 section is 3,8 m and the section of 1+100 - 1+500 is 3,81 m. From the results of this study, it is recommended that the government build flood control by constructing embankments with an elevation of +4,5 m from the lowest water level datum (LLWL). Keywords: Flood design, HEC-RAS, tides, water level,

Abstract

The construction of PT. X' depot in Langsa City, Aceh, is located on soft clay soil that requires slope stability analysis for the embankment. This research aims to analyze slope stability using bamboo mattresses and piles as reinforcement to improve the safety factor. The analysis was conducted using manual calculations (Bishop method) and GeoStudio software (also using the Bishop method), under both static conditions and seismic influence (pseudostatic approach with a horizontal seismic coefficient (kh) = 0.18). The manual calculation results showed that the unreinforced slope had a safety factor (SF) of 1.1428 < 1.25 (unstable), which decreased to 0.6711 < 1.1 (unstable) under seismic load. Meanwhile, the GeoStudio software analysis indicated that the unreinforced slope had an SF of 1.256 > 1.25 (stable) but dropped to 0.903 < 1.1 (unstable) under seismic load. The use of 1–4 layers of bamboo piles and matting increased the SF to 1.318–1.35 without seismic influence. Under seismic conditions, the SF of the slope reinforced with 1–4 layers of bamboo piles and matting improved to 0.931–0.97. However, the slope was still considered critical during an earthquake (SF < 1.1).
