These activities have led to an increase in pollution, particularly in the form of marine debris. The distribution of non-submerged marine debris tends to drift and ultimately ends up along the shoreline. This research was conducted from December 2021 to June 2022 at Ancol Gen Beach, Pesawahan, Teluk Betung Selatan, Bandar Lampung. The study aimed to classify and identify the types and weights of marine debris most commonly found at Ancol Gen Beach. Sampling of marine debris was carried out using the line transect method spanning the coastline. The research results revealed that the dominant type of marine debris was single-use plastic, followed by recyclable plastics, textiles, rubber, paper, glass, wood, metal, and hazardous waste (B3). The highest density of marine debris occurred during the rainy season, with a count of 50,020 pcs/m² and a weight of 160,525 g/m². In contrast, the lowest density of marine debris was observed during the dry season, with 15,450 pcs/m² and a weight of 53,250 g/m². The accumulation of macro marine debris along Ancol Gen Beach is suspected to be transported by surface currents and river flows in the vicinity of the shoreline.\u0000Keywords: Ancol Gen, Macro-sized, Marine debris, and Seasson.\u0000Abstrak\u0000Pantai Ancol Gen merupakan salah satu pantai yang berada di perairan Teluk Lampung yang memiliki beragam aktivitas di sekitar perairan tersebut. Aktivitas-aktivitas yang ada menyebabkan peningkatan pencemaran salah satunya berupa sampah laut. Distribusi sampah laut yang tidak tenggelam ke dasar perairan akan hanyut dan berakhir di sepanjang pantai. Penelitian ini dilaksanakan pada bulan Desember 2021- Juni 2022 dan bertempat di Pantai Ancol Gen, Pesawahan, Teluk Betung Selatan, Bandar Lampung. Penelitian bertujuan untuk mengklasifikasi dan mengidentifikasi jenis-jenis serta berat sampah laut yang paling banyak ditemukan di Pantai Ancol Gen. Pengambilan sampel sampah laut menggunakan metode line transek yang membentang sepanjang pantai. Hasil penelitian menunjukkan bahwa jenis sampah laut didominasi oleh sampah jenis plastik sekali pakai, kemudian diikuti oleh sampah plastik daur ulang, tekstil, karet, kertas, kaca, kayu, logam, dan sampah B3. Kepadatan jumlah sampah laut paling tinggi berada di musim hujan sebanyak 50.020 pcs/ m² dan berat sampah laut sebesar 160.525 g/m², sedangkan kepadatan jumlah sampah laut terendah di musim kemarau sebanyak 15.450 pcs/m² dan berat sampah laut sebesar 53.250 g/m².

The purpose of this study was to identify gastropod species and the density of each species that were found attached to the hard substratum in the tidal area of Bulo, Mandolang District, North Sulawesi. Data were collected by line transect and squared methods. Gastropod samples obtained were treated by using 70% alcohol. The length of each species was measured before being identified at the species level. The results show 175 individuals consisting of 30 species from 14 families were recorded. Substrat of rock and dead coral were covered and dominated the intertidal bottom. The highest density of Gastropods in the tidal area of Bulo, Mandolang District, North Sulawesi was the species of Cellana radiata. The density of Cellana radiata was 3.8 ind./m², while for the other 20 species of gastropods, each species was 0.07 ind./m².

All species of sea cucumbers found in the surveyed areas were collected. Following the collection, sorting was conducted where only two individuals of each morphological type, color, and other similar traits were kept, while the rest were returned to the waters. The sorted samples were then photographed for identification purposes, and to analyze the density of the discovered sea cucumber species, the number of individuals per suspected species was noted. The images of the collected samples were then compared with a guide for species identification. The World Register of Marine Species (WORMS) 2023 guide was used for this purpose. Subsequently, the number of individual species found was analyzed to determine the density of individuals and the abundance of sea cucumber species. The results of the identification process revealed 7 species with a total of 53 individuals. \u0000Keywords: Teripang, Holothuroidea, Likupang \u0000Abstrak \u0000Teripang atau Holothuroidea merupakan salah satu dari kelas Echinodermata. Semuah golongan organisme ini memiliki ciri kulit yang berduri atau yang berbintil atau tersusun dari sat-sat kapur. Beberapa jenis teripang merupakan komoditi perikanan yang diperdaganngkan secara Internasional. Perburuan teripang tidak saja pada jenis-jenis yang berharga mahal, tetapi juga pada jenis-jenis yang berharga murah yang pada awalnya tidak memiliki perhatian. \u0000Metode pengambilan sampel diawali dengan survei lokasi pada siang hari dan pengambilan sampel pada malam hari saat surut terendah dengan menggunakan senter sebagai alat penerang. Spesies yang diambil adalah semua jenis teripang yang ditemukan di perairan tesebut. Setelah teripang terkumpul dilanjutkan dengan penyortiran dimana hanya di ambil dua individu setiap bentuk morfologi, warna dan ciri lainnya yang sama. Sedangkan sisanya dikembalikan ke perairan. Sampel yang telah disortir, lalu difoto untuk keperluan iderntifikasi, kemudian untuk menganalisis kepadatan jenis teripang yang ditemukan dicatat jumlah individu setiap jenis yang điduga merupakan spesies/jenis yang sama. Sampel yang telah diambil foto/gambarnya dicocokkan dengan gambar panduan untuk identifikasi jenis. Panduan untuk mengidentifikasi digunakan WORMS (2023) Selanjutnya jumlah jenis individu yang ditemukan dianalisi untuk mendapatkan kepadatan individu dan kelimpahan spesies teripang. Hasil identifikasi ditemukan 7 spesies dengan ju","PeriodicalId":331202,"journal":{"name":"Jurnal Ilmiah PLATAX","volume":"13 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139005497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to map changes in the coastline in Sungai Nibung Village using multi-temporal imagery for 2013-2023 from Google Earth Engine (GEE). The benefit of this research is to see changes in the coastline of Sungai Nibung so that coastal area management, including abrasion disaster mitigation, can be carried out appropriately. The method used is a quantitative descriptive method from the results of processed NSM and EPR data from DSAS and the results of Landsat image digitization from GEE. The most extensive abrasion phenomenon results will occur in 2023, namely 64,924 m2 and accretion of 120,886 m2. Coastal changes digitized using ArcGIS showed that the coastline change in 2013 was 0.433 km2, in 2016 it was 0.521 km2, in 2019 it was 0.538 km2 and in 2023 it was 0.649 km2. DSAS analysis shows that almost every stretch of beach in Sungai Nibung has experienced abrasion. Abrasion in Sungai Nibung occurred because there were not many wave breakers and damage to mangrove land. The rate of abrasion in Sungai Nibung over 10 years reached -574.96 m.\u0000Keywords: DSAS, EPR, NSM, Google Earth Engine.\u0000Abstrak\u0000Perubahan garis pantai menyebabkan proses terus menerus melalui berbagai proses baik abrasi maupun akresi pantai yang diakibatkan oleh pergerakan sedimen, arus susur pantai. Penelitian ini bertujuan untuk memetakan perubahan garis pantai di Desa Sungai Nibung menggunakan citra multi temporal tahun 2013-2023 dari Google Earth Engine (GEE). Manfaat penelitian ini untuk melihat perubahan pesisir pantai Desa Sungai Nibung  maka pengelolaan kawasan pesisir termasuk di dalamnya mitigasi bencana abrasi dapat dilakukan dengan tepat. Metode yang digunakan adalah metode deskriptif kuantitatif dari hasil olahan data NSM dan EPR dari DSAS dan hasil digitasi Citra Landsat dari GEE. Hasil fenomena abrasi paling luas terjadi di tahun 2023 yaitu 64,924 m2 dan akresi sebesar 120,886 m2. Perubahan pesisir yang digitasi menggunakan ArcGIS diperoleh perubahan garis pantai tahun 2013 sebesar 0,433 km2 , tahun 2016 sebesar 0,521 km2 , tahun 2019 sebesar 0,538 km2 dan tahun 2023 sebesar 0,649 km2. Analisis DSAS hampir di setiap ruas pantai di Desa Sungai Nibung mengalami abrasi. Abrasi di Desa Sungai Nibung terjadi akibat belum banyak pemecah ombak dan rusaknya lahan mangrove.
