“…Peningkatan kunjungan wisata di Pantai Tanjung lesung membuat pengelola harus membangun fasilitas umum (BPS Provinsi Banten, 2022). Pembangunan fasilitas umum menimbulkan alih fungsi penggunaan lahan dan aktivitas lain yang dapat meningkatkan potensi kerusakan wilayah pesisir (Hendriyono et al, 2015;Arjasakusuma et al, 2021;Widodo et al, 2022).…”

Pantai Tanjung Lesung merupakan proyek strategis nasional yang menjadi potensi wisata pantai untuk perkembangan perekonomian Provinsi Banten. Kerusakan daerah pesisir telah terjadi dari tahun ke tahun di wilayah ini. Kondisi ini perlu dilakukan mitigasi untuk mengurangi resiko rusaknya infrastruktur dan sangat mengganggu permukiman, pariwisata, dan aktivitas masyarakat yang lain. Penelitian ini bertujuan untuk memprediksi perubahan garis pantai di Pantai Tanjung Lesung yang terjadi dalam 25 (2002 – 2047) tahun yang akan datang. Hasil penelitian ini diharapkan dapat menjadi pertimbangan dalam perencanaan pengembangan wisata pantai dengan mencegah terjadinya abrasi dan akresi di titik-titik krusial. Pemodelan perubahan garis pantai pada penelitian ini, menggunakan modul LITLINE, salah satu modul utama dari LITPACK dari MIKE 21. Pengumpulan data dilakukan dengan survey lapangan dan pengambilan data dari instansi terkait. Analisis hasil model perubahan garis pantai di Pantai Tanjung Lesung, Kab. Pandeglang menunjukkan potensi terjadinya proses abrasi dan akresi untuk 25 tahun ke depan. Selama 25 tahun dari tahun 2022 – 2047 garis pantai Tanjung Lesung mengalami abrasi sebesar 48.69 m dan akresi sebesar 51,7 m. Nilai rata – rata perubahan garis pantai adalah 11,5 dan 11,75 pada kejadian abrasi dan akresi secara berurut. Akumulasi akresi dengan kala periode 5 tahun hingga 2047 di daerah teluk adalah sebesar 61,65 m, sedangkan akumulasi abrasi dengan kala periode 5 tahun hingga 2047 adalah sebesar 72,49 m. Tanjung Lesung Beach is a national strategic project that becomes a potential for coastal tourism for the economic development of Banten Province. Damage to coastal areas has occurred from year to year in this region. This condition needs to be mitigated to reduce the risk of infrastructure damage and greatly disrupt settlements, tourism, and other community activities This study aims to predict shoreline changes at Tanjung Lesung Beach that will occur in the next 25 (2002–2047) years.. The results of this study are expected to be considered in planning the development of coastal tourism by preventing abrasion and accretion at crucial points. The modeling of shoreline changes in this study uses the LITLINE module, one of the main modules of LITPACK from MIKE 21. Data collection is carried out by field surveys and data collection from relevant agencies. Analysis of the results of the model of shoreline change at Tanjung Lesung Beach, Pandeglang district shows the potential for abrasion and accretion processes for the next 25 years. For 25 years, from 2022 to 2047, the Tanjung Lesung coastline experienced 48.69 m of abrasion and 51.7 m of accretion. The average value of shoreline change is 11.5 and 11.75 for accretion and sedimentation events, respectively. The accumulation of accretion with a period of 5 years to 2047 in the bay area is 61.65 m, while the accumulation of abrasion with a period of 5 years to 2047 is 72.49m.

“…Seiring dengan meningkatnya kebutuhan penduduk dan perkembangan teknologi, eksploitasi pantai menjadi semakin sering (Panggabean et al, 2015). Intervensi manusia seperti pembangunan pelabuhan, peningkatan fasilitas wisata dan aktivitas pantai lainnya mengakibatkan terjadinya perubahan penggunaan lahan dan juga menjadi salah satu penyebab kerentanan di wilayah pesisir, seperti erosi, akresi, dan sedimentasi (Hendriyono et al, 2015;Marfai et al, 2020;Septiangga dan Mutaqin, 2021;Marfai et al, 2021). Rencana perubahan penggunaan lahan ini tentunya berpotensi mempengaruhi keseimbangan ekosistem alam dimasa mendatang, termasuk garis pantai (Septiangga dan Mutaqin, 2021).…”

Part of the coastal area of Pandeglang Regency in Banten Province is a developing area with a high level of human activity in the form of industrial and tourism activities. Observation and management of the dynamics of coastal areas, especially related to the shoreline, are important studies in supporting the sustainability of communities in coastal areas. Shoreline changes can be identified using remote sensing technology, Geographical Information Systems (GIS), and statistical analysis. Analysis of the shoreline rate was carried out using the Digital Shoreline Analysis System (DSAS) software. The statistical methods used are Net Shoreline Movement (NSM) and End Point Rate (EPR). In general, the shoreline in some coastal areas of Pandeglang experiences accretion and erosion. The farthest accretion is shown in the area around PLTU Labuan Port as far as 696.48 meters with a change rate of 19.88 meters/year. This indicates that land reclamation is one of the factors that induce the accretion process in the area. Meanwhile, the largest erosion occurred in Tanjung Lesung as far as -135.08 meters with a rate of change of -4.50 meters/year.

“…The dominant wave directions for the wet and dry seasons are eastward and westward, respectively. As waves approach and break along the coast, sediment moves alongshore in the direction of wave travel [27,28]. In this area, the general trend of sediment transport by longshore current moves from west and north-west to east [28,29].…”

Transferability and Upscaling of Fuzzy Classification for Shoreline Change over 30 Years

Local authorities require information on shoreline change for land use decision making. Monitoring shoreline changes is useful for updating shoreline maps used in coastal planning and management. By analysing data over a period of time, where and how fast the coast has changed can be determined. Thereby, we can prevent any development in high risk areas. This study investigated the transferability of a fuzzy classification of shoreline changes and to upscale towards a larger area. Using six sub areas, three strategies were used: (i) Optimizing two FCM (fuzzy c-means) parameters based on the predominant land use/cover of the reference subset, (ii) adopting the class mean and number of classes resulting from the classification of reference subsets to perform FCM on target subsets, and (iii) estimating the optimal level of fuzziness of target subsets. This approach was applied to a series of images to identify shoreline positions in a section of the northern Central Java Province, Indonesia which experienced a severe change of shoreline position over three decades. The extent of shoreline changes was estimated by overlaying shoreline images. Shoreline positions were highlighted to infer the erosion and accretion area along the coast, and the shoreline changes were calculated. From the experimental results, we obtained m (level of fuzziness) values in the range from 1.3 to 1.9 for the seven land use/cover classes that were analysed. Furthermore, for ten images used in this research, we obtained the optimal m = 1.8. For a similar coastal characteristic, this m value can be adopted and the relation between land use/cover and two FCM parameters can shorten the time required to optimise parameters. The proposed method for upscaling and transferring the classification method to a larger, or different, areas is promising showing κ (kappa) values > 0.80. The results also show an agreement of water membership values between the reference and target subsets indicated by κ > 0.82. Over the study period, the area exhibited both erosion and accretion. The erosion was indicated by changes into water and changes from non-water into shoreline were observed for approximately 78 km2. Accretion was due to changes into non-water and changes from water into shoreline for 19.5 km2. Erosion was severe in the eastern section of the study area, whereas the middle section gained land through reclamation activities. These erosion and accretion processes played an active role in the changes of the shoreline. We conclude that the method is applicable to the current study area. The relation between land use/cover classes and the value of FCM parameters produced in this study can be adopted.
