One common damage to seagrasses is the uprooting of seagrasses when the anchors of ships moored in seagrass areas are lifted. Seagrass that is uprooted little by little over time will leave a damaged area (not overgrown with seagrass). The next impact is sediment resuspension that easily occurs due to waves. It is suspected that sediment resuspension released some of the material contained in the sediment, including other nutrients. The research was conducted to see the impact of damage due to ship anchors on changes in nutrient concentrations, especially nitrate and phosphate. The research was conducted on three islands: Bonebatang Island, Bonetambung Island, and Barranglompo Island. All three are included in the Makassar Spermonde Archipelago, South Sulawesi Province. Sediment sampling was carried out on the damaged seagrass area and the surrounding area, which was used by the community to moor ships. On the three islands, samples were taken from 6 ex-seagrass areas with varying areas and the surrounding seagrass areas. In both areas, samples were taken three times each. Sediment 10 cm thick on the surface was taken using a corer. Analysis of nitrate using the ascorbic acid method and phosphate analysis using the brain method by reading absorbance using a spectrophotometer. The results showed a decrease in the concentration of nitrate and phosphate in the sediments due to the damage to seagrass due to ship anchors on the three islands. The more extensive the seagrass damage, the higher the decrease in nitrate concentration on the three islands, but the decrease in phosphate concentration only relates to the extent of seagrass damage on Barranglompo Island.","PeriodicalId":294614,"journal":{"name":"Maspari Journal : Marine Science Research","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125139288","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}

Keindahan pantai dapat meningkatkan perekonomian masyarakat ternyata diikuti oleh ancaman gelombang swell dari Samudera Hindia. Struktur pelindung pantai yang umumnya digunakan adalah breakwater. Di Indonesia, sangat banyak dijumpai breakwater yang memiliki gradien kemiringan 1:2. Semakin besar gradien kemiringan breakwater maka semakin banyak volume armor breakwater yang digunakan, sehingga berdampak pada besarnya biaya pembangunan breakwater. Oleh sebab itu, penelitian ini mengkaji konfigurasi gradien kemiringan pada submerged breakwater. Penilitian ini berfokus pada struktur submerged breakwater dikarenakan puncak strukturnya berada di bawah muka air sehingga ramah bagi pantai wisata. Penelitian ini menggunakan variasi gradien kemiringan struktur 1:2 dan 1:1.5, sedangkan diameter pori struktur submerged breakwater adalah 2 cm. Berdasarkan hasil yang diperoleh, struktur submerged breakwater dengan kemiringan 1:1.5 puncak tanpa lubang menghasilkan kecepatan arus yang besar, nilai koefisien tranmisi gelombang terkecil dan presentase efektifitas struktur yang paling besar. Peneliti berkesimpulan bahwa kemiringan gradien struktur submerged breakwater sangat berpengaruh terhadap penjalaran gelombang. Semakin besar kecuraman struktur submerged breakwater maka semakin efektif dalam mengurangi tinggi gelombang datang. Selain itu, kondisi tersebut juga sangat dipengaruhi oleh kondisi gelombang datang. Sehingga disain submerged breakwater dapat menjadi kunci bagi transport sedimen dan perubahan batimetri di pantai wisata.Kata Kunci : pantai, gelombang, erosi, submerged breakwater","PeriodicalId":294614,"journal":{"name":"Maspari Journal : Marine Science Research","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133765661","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}
