Abstract

The purpose of this study is to determine the rate of shoreline change and the level of abrasion in Bukit Batu District, Bengkalis Regency, Riau Province based on several physical variables in the coastal area. End Point Rate (EPR) is a method that can be used to calculate the rate of shoreline change by displaying transects according to their category (high abrasion, medium abrasion, low abrasion, stable, and accretion). From 1991-2021 there was an abrasion of ±139.71 m equivalent to ±4.65 m/year which mostly occurred in Sukajadi Village and Pangkalan Jambi Village, while accretion of ±27.51 m equivalent to ±1.58 m/year mostly occurred in Pakning Asal Village and Sejangat Village. Moderate abrasion is the predominant type. Sukajadi and Pangkalan Jambi are villages that have experienced high levels of abrasion. The area affected by abrasion has moderate and fast currents as well as coastal protection in the form of mangroves, most of which have been damaged and require repairs. Therefore, the main factors causing the abrasion are thought to be the lack of coastal protection and high-speed currents and waves flowing from the Malacca Strait.

Abstract

Mangrove forest vegetation is spread across several islands in Indonesia, including Rupat Island. Rupat Island is the outermost island in Riau Province, close to Malaysia, and directly faces international waters, namely the Malacca Strait. Rupat Island has two sub-districts, namely Rupat District and North Rupat District. Rupat Island has a very extensive mangrove forest and has a significant contribution. Monitoring changes in mangrove forests is one way of controlling the mangrove forest ecosystem. This research aims to analyze changes in mangrove vegetation area and mangrove density using the MVI algorithm in 2013 and 2023 on Rupat Island, Bengkalis Regency. This research was conducted in the mangrove forest ecosystem on Rupat Island, Bengkalis Regency, Riau Province. The method used in this research is a survey method with observation and field data collection (ground check). Based on image processing results, the area of ​​mangrove vegetation was 13903.03 ha (2013) to 11748.66 ha (2023) and experienced a reduction of 2154.37 ha. Classification based on MVI in sparse density has an area of ​​5872.46 ha (2013), decreasing to 3422.05 ha (2023); medium density has an area of ​​2188.84 ha (2013), increasing to 3334.64 ha (2023), and dense density has an area of ​​5841.73 ha (2013) reduced to 4991.97 ha. Over 10 years, the density of mangrove vegetation has increased in the medium class and tends to decrease in the sparse and dense classes. Based on calculations, the density of mangroves on Rupat Island falls into the tree category, ranging from 1150.00 ind/ha to 1450.00 ind/ha, which is considered good, and the sapling category ranges from 366.67 ind/ha to 1050.00 ind/ha, which is classified as good.

Abstract

Perubahan garis pantai akibat abrasi dan akresi merupakan fenomena dinamis yang dipengaruhi oleh faktor oseanografi dan aktivitas manusia. Penelitian ini bertujuan untuk menganalisis perubahan abrasi dan akresi serta karakteristik sedimen di Pantai Apar, Pariaman, guna mendukung upaya pengelolaan wilayah pesisir yang berkelanjutan. Penelitian dilaksanakan pada Januari 2024 dengan menggunakan metode survei in situ untuk memperoleh data arus, gelombang, dan sedimen, serta analisis citra satelit Landsat selama 20 tahun (2004–2024) menggunakan Digital Shoreline Analysis System (DSAS) dengan pendekatan End Point Rate (EPR). Hasil menunjukkan bahwa pada periode 2004–2014, terjadi akresi tinggi di seluruh area penelitian dengan rata-rata laju 4,51 m/tahun. Namun, pada periode 2014–2024 terjadi dominasi abrasi, dengan rata-rata laju abrasi sebesar -2,38 m/tahun. Secara keseluruhan, dalam rentang 20 tahun, garis pantai mengalami akresi sedang dengan rata-rata perubahan 0,737 m/tahun. Sedimen di Pantai Apar didominasi pasir kasar dan sedang (0,23–0,9 Ø), dengan sortasi buruk hingga sedang dan skewness mengarah ke partikel halus. Kecepatan arus berkisar 0,08–0,26 m/s dan tinggi gelombang 0,25–0,51 m, termasuk kategori rendah. Kondisi oseanografi ini mendukung akumulasi sedimen dan akresi di sebagian besar wilayah pantai. Hasil penelitian ini dapat dijadikan dasar dalam perencanaan mitigasi abrasi serta pengelolaan pantai yang berkelanjutan.
