Abstract

ABSTRAKLamun merupakan tumbuhan yang dipengaruhi oleh komposisi jenis substrat di daerah mangrove dan terumbu karang. Penelitian ini dilakukan untuk mengetahui kerapatan dan tutupan jenis lamun di perairan pantai Ketapang, Kecamatan Sekotong Barat, Kabupaten Lombok Barat. Penelitian ini menggunakan metode transek kuadrat yang berukuran 50x50 cm2 pada tiga lokasi yang berbeda. Stasiun 1 dekat habitat mangrove, stasiun 2 habitat lamun dan stasiun 3 dekat dengan terumbu karang. Hasil penelitian terdapat 4 jenis lamun yang ditemukan yaitu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, dan Halophila ovalis. Kerapatan dan tutupan jenis lamun tertinggi ditunjukkan pada jenis Cymodocea rotundata pada stasiun 1 dan 2 sedangkan pada stasiun 3 jenis lamun yang memiliki kerapatan dan tutupan tertinggi adalah jenis Enhalus acoroides. Secara keseluruhan tutupan jenis lamun di perairan pantai Ketapang tergolong dalam kategori sedang. Kata Kunci: Kerapatan, Ketapang, Lamun, Sekotong, TutupanABSTRACTSeagrass is a plant that is influenced by the composition of the type of substrate in mangrove areas and coral reefs. This research was conducted to determine the density and cover of seagrass species in the coastal waters of Ketapang, West Sekotong District, and West Lombok Regency. This study used the quadratic transect method measuring 50x50 cm2 at three different locations. Station 1 is near the mangrove habitat, station 2 is the seagrass habitat, and station 3 is close to coral reefs. The results of the study found that 4 types of seagrass were found, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, and Halophila ovalis. The highest density and cover of seagrass species were shown in Cymodocea rotundata at stations 1 and 2, while at station 3 the seagrass species that had the highest density and cover was Enhalus acoroides. Overall, the cover of seagrass species in the coastal waters of Ketapang is classified as medium. Keywords: Density, Ketapang, Seagrass, Sekotong, Cover

Abstract

Kaung Island has the potential for seagrass ecosystems which are important ecosystems for the survival of various types of aquatic biota. Rahmawati et al., (2014) said that seagrass damage is caused by natural and human factors, especially those who are active in coastal areas. This is due to a lack of understanding and public awareness. As for the things that need to be done for the sustainability of seagrass ecosystems, namely by providing understanding to the community starting from identifying species, benefits and monitoring or data collection. The purpose of this service activity is to provide understanding to the community regarding seagrass ecology which includes types, benefits, status and threats as well as monitoring the condition of seagrass ecosystems. The method used in this service is in the form of counseling by resource persons and discussions regarding the role of seagrass ecosystems and the damage they face, as well as how to monitor seagrass cover. The results of the community service activities show that the community is very enthusiastic about being actively involved in efforts to manage seagrass ecosystems and monitoring results show that seagrass conditions at the location are included in the less rich category with a percentage of 37.5% with the highest percentage of species cover shown by Enhalus acoroides and Thalassia hemprichii. It is necessary to carry out transplant activities which are an effort to overcome the problem of the condition of the seagrass ecosystem in Mutiara Beach so that the function of the seagrass ecosystem can be ecologically sustainable, considering that the seagrass ecosystem in the area provides economic services to the people in the coastal area of Mutiara Beach. Service activities are very beneficial to the community, and have changed their mindset such as their understanding and awareness.

Metode yang digunakan dalam penelitian ini yaitu deskriptif eksploratif. Titik pengambilan data dibagi menjadi 3 stasiun, setiap stasiun diulang sebanyak 3 kali. Pengambilan data kualitas air meliputi suhu, salinitas, pH dan oksigen terlarut. Hasil penelitian menunjukkan suhu berkisar 28-29°C, Salinitas berkisar 32.7-33 ppt, pH berkisar 7.3-7.5, dan oksigen terlarut berkisar antara 7.3-7.8 mg/L. Kualitas perairan pesisir Pantai Ketapang berdasarkan PP No. 22 Tahun 2021 masih memenuhi standar baku mutu kehidupan organisme maupun biota perairan serta ekosistem dan wisata bahari.

Abstract

Tujuan dari kegiatan penelitian adalah untuk mengetahui efektivitas konsentrasi nitrat terbaik untuk kepadatan Chaetoceros sp. Penelitian ini dilaksanakan pada bulan Oktober-November 2011 di PT Bibit Unggul Dusun Lempenge Desa Rempek Kecamatan Gangga Kabupaten Lombok Utara Provinsi Nusa Tenggara Barat. Metode yang digunakan dalam penelitian ini adalah metode eksperimental dengan Rancangan Acak Lengkap (RAL) menggunakan enam konsentrasi perlakuan nitrat dan tiga kali pengulangan sehingga terdapat 18 unit percobaan. Adapun percobaan perlakuan konsentrai nitrat 0 ppm (K1), 100 ppm/L (K2), 125 ppm/L (K3), 150 ppm/L (K4), 175 ppm/L (K5), dan 200 ppm/L (K6). Parameter yang diamati dalam penelitian ini meliputi kepadatan Chaetoceros sp dan parameter kualitas air. Hasil penelitian menunjukkan bahwa nilai kepadatan tertinggi ditunjukkan pada perlakuan konsentrasi nitrat 200 ppm/L namun tidak memberikan pengaruh yang nyata. Parameter kualitas air dalam penelitian menujukkan nilai yang masih sesuai untuk pertumbuhan chaetoceros sp.

Abstract

Ketapang coastal waters, West Lombok Regency is a coastal area where seagrass ecosystems are distributed, but so far there has been no research data explaining the condition of seagrass ecosystems. This study aims to determine the condition of the seagrass ecosystem in the coastal waters of Ketapang, West Lombok Regency. This research was conducted in November 2021 which is located in the coastal waters of Ketapang, West Lombok Regency. Sampling was carried out by purposive sampling method consisting of 3 observation stations. Seagrass samples were collected using line transects and quadrant transects measuring 50×50 cm2. The parameters observed included physical and chemical water quality, as well as seagrass density and coverage. The results of water parameter measurements are still at the threshold of water quality standards. The seagrass found were Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, and Halophila ovalis. The highest seagrass density was at station 1, 407 shoots/m2, while the lowest density was at station 3, 211 shoots/m2. The condition of the highest seagrass cover was found at station 1 and the lowest cover was found at stations 2 and 3.

Abstract

Coral diseases and health disorders are among the primary factors threatening the survival and sustainability of coral reef ecosystems. Coastal areas, particularly those adjacent to human settlements, are highly vulnerable to environmental pressures arising from both natural and anthropogenic factors. One such area is the coastal waters of Pantai Mutiara, Pulau Kaung Village. This study aims to identify the types of coral diseases and health disorders present in the area and to assess the environmental factors influencing their occurrence. The research was conducted from April to May 2025 in the coastal waters of Pantai Mutiara. Data collected included the types of coral diseases and health disorders, as well as water quality parameters. Field observations were carried out through direct documentation of infected corals, which were subsequently identified using the Underwater Cards for Assessing Coral Health on Indo-Pacific Reefs. The results revealed several coral diseases and health disorders, namely White Syndrome, Bleaching, Algal Competition, and Sediment Damage. These conditions are presumed to be associated with both anthropogenic activities and natural environmental factors. The highest overall prevalence was recorded at a depth of 4 meters, reaching 25%. Bleaching was most frequently observed at a depth of 2 meters, affecting three coral colonies. According to the Indonesian Government Regulation No. 22 of 2021, the water quality in the study area remains within acceptable standards, indicating that the environmental condition is still adequate to support coral growth and survival. Keywords: Prevalence, Diseases, Health Disorders, Coral, Pearl Beach Waters.
