Abstract

The eruption of Mount Krakatau in 2018, along with high waves, has impacted the coastal conditions of Kalianda Beach. The parameters for planning the revetment include significant wave height, highest high water level (HHWL), refraction and shoaling coefficients, wave set-up, and SLR. Wave data processing was conducted using the FT Type I. The extreme wave 50-year period has a height (Hr) of 2.22 m and a period (Tr) of 14.67 s. The wave transformation coefficients for refraction and shoaling, which are 0.74 and 1.44 respectively, lead to a deformation wave height of 2.19 m at a depth of 5 m. Admiralty tide analysis yielded a tidal range element at MSL of 0.94 m, which serves as the datum for elevation point 0. The HHWL from MSL is 0.73 m, wave set-up is 0.58 m due to breaking waves at 3.43 m, and SLR is 0.16 m, leading to a DWL of 1.46 m. The wave run-up varies according to the type of revetment, boulder type elevations id 4.60 m, tetrapod type is 3.80 m, and dolos type is 4.40 m. Differences elevation are attributed to different wave run-up every type of revetment material, run-up of the type material boulder is 2.83 m, run-up of tetrapod is 2.08 m, and dolos is 2.67 m.

Abstract

Daerah Irigasi Punggur Utara, bagian dari Sistem Sekampung, mencakup 132,28 hektar di Kabupaten Lampung Tengah, Lampung Timur, dan Kota Metro. Tantangan utamanya adalah distribusi air yang tidak efisien, menyebabkan pemborosan dan persaingan atas sumber daya air yang terbatas. Untuk mengatasi masalah ini, pintu air dioptimalkan dengan menyesuaikan hubungan antara ketinggian pintu dan kebutuhan air. Daerah ini mengikuti pola tanam Padi-Padi-Bera, dengan data curah hujan dari tahun 2014-2023 menunjukkan puncak 5,13 mm/hari pada bulan Maret. Kebutuhan air berkisar dari 0,04 m³/detik di bulan April hingga 0,20 m³/detik di bulan Mei. Pintu air Crump de Gruyter, dengan lebar 0,75 meter dan koefisien 0,913, mengatur aliran air. Bukaan pintu 5 cm menyediakan 0,20 m³/detik untuk memenuhi kebutuhan tertinggi, sedangkan bukaan 1 cm menghasilkan 0,04 m³/detik untuk kebutuhan terendah. Optimalisasi dilakukan menggunakan Pemrograman Linear melalui Solver, menyesuaikan ketinggian pintu untuk memenuhi kebutuhan irigasi dalam batas kapasitas.

Abstract

The Way Mincang River, which is located in Pardasuka District, Pringsewu Regency, Lampung Province, is a periodic river whose flow often overflows during rainy season. The overflow of the Way Mincang River inundated several Pekon in Pardasuka District including the Pekon Tanjung Rusia, Tanjung Rusia Timur, Sukanegeri, Pardasuka and Kedaung. The aim of research to determine the flood discharge with a return period of 10, 25 and 50 years in 2 dimensions with the HEC-RAS v6.2 software, so that the water level and the area of flood-prone distribution in Way Mincang River can be identified. The research location is in Way Mincang Watershed with the downstream of river at coordinates 104.92 BT and -5.50 LS while the upstream of river at coordinates 104.92 BT and -5.57 LS with a river length of 10.29 km, average river width of 15 m-20 m and the study area 2371.34 Ha. The results of analysis show that discharge at periods of 10 years, 25 years and 50 years is 50.29 m3/sec, 63.11 m3/sec and 72.61 m3/sec. The maximum flood water level is 1.88 m in Pekon Pardasuka Timur and the maximum flood area is 0.31 km2 in Pekon Kedaung. Along the Way Mincang watershed is a flood-prone area where the entire pekon (village) is flooded but the coverage area is relatively small, namely <1 km2. This is confirmed by the ratio of total flood inundation and total area of only 5.24%. It is hoped that results of research can be used as a reference for stakeholders in terms of planning and improving Way Mincang Watershed.

Abstract

To begin with, one of the valuable beaches at Pesisir Tengah Krui District is Labuhan Jukung Beach that directly encounters the Indian Ocean and is crossed by tectonic plates. The current position could consequence a tsunami disaster and cause loss and damage to the area at any time soon. In addition, no hazard map released by the National Center for Volcanology and Disaster Mitigation in the study location is one of the shortcomings of tsunami-prone areas in the West Coast tourist area. Tsunami wave propagation model establishment is a monumentally vital step in tsunami mitigation to pinpoint areas which are vulnerable to tsunami disasters and maximize the damage control. One way or another is by utilizing Delft3D 4.04.01 software according to wave propagation simulation scenario analysis. The input for modeling adopts historical tsunami height data which has similar characteristics to the case study location points, simultaneously 3.6 meter, 8 meter and 15 meter. The outcome wave height of 3.6 meter takes within 36 minutes to reach the coast and it does not cause inundation, meanwhile the outcome of waves height of 8 meter and 15 meter are accomplishing a tsunami inundation on land which takes 33 - 35 minutes to approach the coast. The data used in these scenarios demands the model accuracy requirements of modeling validation by inspecting the wavelengths formed in shallow water. Based on all of these scenario modeling results, the maximum propagation scenario for an 8 meter wave height on land is 330 meter, on the other hand for a 15 meter wave height is 450 meter from the coastline.

Abstract

Citing from the National Disaster Management Agency (BNPB) in 2022, abrasion occurred located at Caruban Beach, Gedongmulyo Village, Lasem District, Rembang Regency, Central Java Province. The impact of this abrasion causes a significant change in the coastline. One of the efforts to overcome these problems is to plan coastal protection which is adjusted to the existence of the parameters and urgency on Caruban Beach. The main aims of this research is planning breakwater structure as coastal protection and addressing the abrasion. The parameters used in the planning of coastal protection include significant wave height, tides with HHWL values, refractive coefficients, and shoaling coefficients for the transformation of deep water into shallow water, the raise up of water surface, and Sea Level Rise value. The data on high and significant wave periods are processed using the probability distribution of the Fisher Tippett Type I method at a 50-year return period with high values and extreme wave periods of 2.402 meters and 5.61 seconds, respectively. Waves transformation by the refractive coefficient and shoaling coefficient is derived around 1.57 meters at a depth of 5 meters. HHWL value is earned at 0.928 meters. The value of wave set-up is 0.11 meters, while sea level rise in the best estimate in 2075 is 0.24 meters. So design water level is 1.28 meters. The coastal protection chosen is offshore breakwater because it serves to maintain the position of the coastline and maintain the function of Caruban Beach as tourist destination. Breakwater planning uses three types of protective layers, namely tetrapods, dolos, and boulders, where the wave propagation value on the three types of protective layers is derived consecutively of 0.73 meters, 0.68 meters, and 1.46 meters. Thus, the elevation of the tetrapod, dolos, and boulder protection layers is 2.6 meters respectively, 2.5 meters, and 3.3 meters.
