Abstract

Coral reef is an important underwater ecosystem supporting people?s lives in coastal areas. One of the communities depending on the coral reef ecosystem for its food, livelihood, shoreline protection, and recreation needs is a community in Tunda Island. This research aims to analyze and determine the health status of coral reef in the island using a survey method. It was conducted in July 2018 and July 2019. Underwater photography transects were established at two depth areas of ± 3-4 m (shallow water) and ± 10-11 m (reef slope). Analysis of the results of live coral cover was divided into eight categories of groups based on CPCe output series 4.1. The values of coral reef cover at first depth (± 3-4 m) were 64.86% (east side of the island), 55.76% (north toward east side), and 32.22% (west side). The values of coral reef cover at second depth (± 10-11 m) were 36.36%, 25.00%, and 23.63% on the north toward east, east, and central north sides of the island, respectively. In shallow waters of Tunda Island, the coral reef health is classified as moderate to good, mostly those located on the east and the north toward the east sides. At reef slope, the coral reef health is classified as damaged to poor, particularly those located on the south and the south toward the west sides. The difference in the health values implies that most corals occur in shallow waters while deep corals differ from those near the surface and are not safe from impacts of the activities in the coastal area of Tunda Island.

Abstract

Lamun merupakan salah satu ekosistem yang berperan penting dalam kehidupan di laut. Penelitian ini bertujuan untuk mengetahui struktur komunitas lamun di Perairan Pulau Kumbang Karimunjawa. Pengamatan lamun di lapangan meliputi identifikasi jenis-jenis lamun, menghitung jumlah individu/tegakan, presentase penutupan dari masing-masing jenis/spesies pada transek. Persen penutupan lamun diamati dengan menggunakan transek kuadrat ukuran 1 x 1 m pada hamparan lamun. Transek ini dibagi menjadi 25 buah kisi ukuran 20 cm2. Satu tegakan lamun merupakan suatu kumpulan dari beberapa daun yang pangkalnya menyatu. Jumlah tegakan diamati langsung dengan visual. Hasil penelitian menunjukkan bahwa Komunitas lamun di perairan kawasan Pulau Parang, Karimunjawa, tergolong komunitas campuran (mixed community) yang terdiri dari 1?5 jenis lamun. Telah ditemukan 6 jenis lamun, yaitu Thalassia hemprichii, Cymodocea rotundata, C. serrulata, Halodule pinifolia, Halodule uninervis dan Halophila ovali di perairan Pulau Kumbang, C. serrulata hanya ditemukan pada saat sampling ke dua bulan September 2012. Pada sampling pendahuluan (Juni 2012), jumlah kerapatan jenis lamun (Tegakan/m²) T. hemprichii merupakan yang tertinggi (77.11) sedangkan yang terendah adalah H. pinifolia (0.56). pada sampling kedua, H. uninervis lebih tinggi dari pada T. hemprichii. Frekuensi jenis lamun pada sampling bulan Juni dan september 2012 yang menunjukkan nilai 0-15,67 dan 0-16 dengan T. hemprichii ditemukan lebih sering dari pada jenis lamun yang lain pada kedua waktu sampling. Penutupan spesies lamun (%/m2) pada sampling bulan Juni dan September 2012 menunjukkan nilai 0,11?15.67 dan 0-29.29. Thalassia hemprichii dan Halodule uninervis mempunyai rata-rata penutupan yang tertinggi masing-masing pada sampling September dan Juni 2012.Kata kunci: lamun, jenis, kerapatan penutupan, Pulau Kumbang, KarimunjawaSeagrass is found in shallow waters that have an important role in marine life and is one of the most productive marine ecosystems. This study aims to determine the structure of seagrass communities in Kumbang Island, Karimunjawa. Data collected during observations in the field include species identification, number of individual/stand, percent cover of each species. Percent cover of seagrass was observed by using square transect with size of 1x1 m. Transect was divided into 25 pieces of smaller size i.e. 20 cm2. The stands of seagrass is a collection of several fused leaf base. The number of stands were directly counted. Sampling were done twice i.e. June and September 2012. The results showed that the seagrass community in the waters of Kumbang island, Karimunjawa, can be classified as mixed community consisting of 1-5 types of seagrass. In total, six species of seagrass were found in the area i.e. Thalassia hemprichii, Cymodocea rotundata, C. serrulata, Halodule pinifolia, Halodule ovali and Halophila uninervis. C. serrulata was only discovered during second sampling in September 2012. In the first sampling (June 2012), the density of seagrass (stand/m²) T. hemprichii was the highest (77.11), while the lowest was H. pinifolia (0.56). The results of second sampling showed that H. uninervis was found to be higher than T. hemprichii. Frequency of seagrass types in June and September 2012 showed the value from 0 to 15.67 and 0-16 with T. hemprichii was found more frequently than other types of seagrass during both sampling time. Percent coverage of seagrass species (%/m2) during June and September 2012 showed the value of 0,11-15.67 and 0-29.29, respectively. T. hemprichii and H. uninervis have the highest average percent cover in September and June 2012 sampling.Key words: seagrass, type, density, Kumbang Island, Karimunjawa

Abstract

Kelompok ikan yang menjadi target penangkapan di perairan Kepulauan Karimunjawa antara lain adalah ikan yang berasosiasi dengan ekosistem karang, seperti Kerapu (Epinephelus sp. dan Plectropomus sp.). Kerapu tergolong ikan demersal yang menyukai hidup di antara celah karang atau di dalam gua di dasar perairan. Penelitian ini bertujuan untuk mengetahui kondisi bioekologi ikan Kerapu di Kepulauan Karimunjawa. Penelitian dilakukan pada tahun 2011-2013. Komunitas ikan Kerapu diamati dengan menggunakan metode transek garis pada kedalaman 5-6 dan 10-11 meter. Hasil analisis menunjukkan bahwa ikan Kerapu mempunyai keanekaragaman yang rendah dengan sebaran jenis yang merata di seluruh perairan. Terdapat dominasi jenis di Pulau Cendikian. Kesamaan jenis terdekat pada nilai  >95 % di kedalaman 5-6 meter dan 10-11 meter yang membentuk empat kelompok terdekat. Determinasi jenis ikan Kerapu dengan hasil tingkat kesamaan jenis terdekat dengan nilai >95 % di Pulau Kumbang (sisi utara), Pulau Kembar dan Batu Lawang. Perbedaan indeks ekologi dan kesamaan jenis Kerapu diduga dikarenakan faktor fisik-kimia perairan dan ketersediaan nutrisi serta oleh aktivitas nelayan dan kegiatan masyarakat. Kata kunci: ikan; Kerapu; indeks ekologi; Karimunjawa  Fish target groups in Karimunjawa waters consist of associated coral reef fish species such as grouper (Epinephelus sp. and Plectropomus sp.). This study aims to determine bioecology the condition of grouper in Karimunjawa waters. The study was conducted during 2011-2013. Data collection was performed using line transect method at 5-6 and 10-11 meters depth. The ecological value of grouper in waters Karimunjawa showed low diversity and the species of groupers is evenly distributed across the waters. There is species dominance in Cendikian Island. The species also showed closest similarity (> 95 %) in both the depth and formed 4 groups. The closest similarity (??> 95 %) happened among the waters of north side of Kembang Islands Beetles (north side),  Kembar Island and Batu Lawang. The condition of groupers in Karimunjawa waters is affected by physical-chemical factors, the availability of nutrients, fishing activities and community activity.   Keywords: fish; grouper; ecological index; Karimunjawa

Abstract

Program pengobatan massal filariasis telah dilakukan selama tiga tahun berturut-turut di KabupatenMamuju Utara, namun penilaian terhadap keberhasilan pelaksanaan pengobatan tersebut belum pernahdilakukan. Untuk mengetahui perubahan situasi filariasis serta perubahan pengetahuan, sikap dan perilakumasyarakat pasca tiga tahun pelaksanaan pengobatan massal, telah dilakukan Survei Darah Jari (SDJ) danwawancara pada masyarakat setempat dari bulan Maret sampai dengan November 2015. Survei darah jaridilakukan di dua desa terpilih pada masyarakat yang berusia lima tahun keatas (? 5 tahun), dan wawancaradilakukan pada masyarakat di 30 desa terpilih yang berusia lima belas tahun keatas (? 15 tahun). Hasilpenelitian menunjukkan bahwa angka microfilaria rate di Kabupaten Mamuju Utara sebesar 1,39%, dengan spesies Brugia malayi. Hasil wawancara terhadap 1.586 responden menunjukkan bahwapengetahuan tentang penyakit filariasis dan kegiatan pengobatan massal masih rendah, demikian halnyadengan perilaku masyarakat terkait pencegahan dan konsumsi obat massal. Sebaliknya masyarakatcenderung bersikap positif terhadap kegiatan pencegahan, pengendalian dan pengobatan filariasis. Angkamicrofilaria rate yang masih diatas 1% (?1%), serta pengetahuan dan perilaku masyarakat tentang penyakitfilariasis dan perilaku masyarakat terkait pencegahan dan konsumsi obat massal masih kurang, hal inimenunjukkan pelaksanaan POMP belum menunjukan hasil seperti yang diharapkan. Disarankan kegiatanpengobatan massal filariasis di Kabupaten Mamuju Utara masih perlu dilanjutkan sampai dengan limatahun, sesuai dengan prosedur dan dilakukan pemantauan yang ketat terhadap daerah dengan kasus kronisdan positif mikrofilaria.

Abstract

The exploitation of Napoleon fishery rates (Cheilinus undulatus) in the past year has been higher. Some areas inIndonesia are still doing the fishing business. Since the napoleon fish was registered in the IUCN red list &Appendix II of CITES, the export quota of 3,600 fishes per year was applied up to the year 2011. In order tosupport the evaluation size in the water bodies around Sinjai and Bone of the determination of napoleon fishprotection status, this study aims to determine fish population South Sulawesi. The method used was SnorkelingVisual Census (SVC). The results obtained indicate napoleon fish abundance is low (0 to 4 individuals/ha). Highestabundance of napoleon fish was found in Lapoipoi & Batanglampe, however none in three locations, i.e., Larearea,Pasiloange and Malambere. It is suggested that protection to species & its habitat is done in four locations wherethe napoleon fish were found, especially in Lapoipoi & Batanglampe.Keyword: napoleon fish, density, Sinjai, Bone, South Sulawesi

Abstract

Kemunculan hiu paus di Desa Botubarani Teluk Tomini Gorontalo menjadi fenomena langka bagi masyarakat setempat. Kegiatan pengamatan kemunculan hiu paus (Rhincodon typus) dilakukan pada bulan April dan Mei 2016 di Teluk Tomini Gorontalo. Metode penelitian yang digunakan adalah pengamatan bawah air untuk mengidentifikasi hiu paus dan tingkah lakunya. Pengukuran kualitas air dan pengambilan sampel plankton dan larva dilakukan disekitar lokasi kemunculan hiu paus. Selama pengamatan ditemukan lima ekor hiu paus dengan ukuran berkisar 3-8 m. Tingkah laku hiu paus yang teramati oleh penyelam, hiu paus muncul dari kedalaman >100 m kemudian berenang berputar-putar pada kedalaman 15-20 m sesekali membuka mulutnya untuk menyaring makanan. Hasil pengamatan kualitas air disekitar lokasi kemunculan hiu paus, nilai salinitas berkisar antara 31,96-33,23 0/00, nilai oksigen terlarut berkisar 6,02-7,48 mg.l-1. Kelimpahan zooplankton tertinggi diperoleh pada pengamatan bulan April yaitu Acartia sp. dari kelas Crustaceae dengan kelimpahan 12385 ind.l-1. Kelimpahan larva disekitar lokasi kemunculan hiu paus didominasi oleh copepod dan larva ikan. Faktor makanan diduga menjadi salah satu faktor munculnya hiu paus di Teluk Tomini.

Abstract

Ikan napoleon (Cheilinus undulatus) adalah jenis ikan karang yang bernilai jual sangat tinggi. Hal ini menyebabkan penangkapan jenis ikan karang yang semakin langka ini menjadi cukup intensif. Saat ini populasi ikan napoleon cenderung menurun dan akan semakin sedikit jika dilakukan penangkapan tanpa batas, meskipun jenis ikan ini telah dilindungi (Appendix II CITES dan KEPMEN No.37/KEPMEN-KP/2013). Penelitian ini dilakukan dengan tujuan untuk menganalisis kepadatan populasi ikan napoleon dan status pemanfaatannya. Untuk menghitung kepadatan ikan digunakan metode sensus visual (UVC). Untuk mengetahui status pemanfaatan dilakukan sebaran frekuensi panjang ikan, yang dilanjutkan dengan penghitungan laju eksploitasi. Hasil analisis menunjukkan bahwa kepadatan ikan napoleon di sekitar perairan Sinjai (Sulawesi Selatan) adalah rendah (1,8 individu/ha). Dari penghitungan laju eksploitasi, diperoleh gambaran bahwa populasi ikan napoleon di perairan sekitar Sinjai - Sulawesi Selatan telah mengalami lebih tangkap. Dari hasil ini disarankan agar perdagangan ikan napoleon masih tetap diperbolehkan dengan syarat mengikuti ketentuan ukuran dan kuota ekspor. Estimasi kuota ekspor ikan napoleon harus berdasarkan data biologi dan dinamika populasi ikan tersebut agar reproduksi alamiah ikan napoleon dapat berlangsung seimbang dengan tingkat eksploitasinya.Napoleon wrasse (Cheilinus undulatus) is a group of reef fish that is  high economic value. This led to the capture of reef fish species that is becoming increasingly scarce intensive enough. Currently napoleon fish populations tend to decline and will be less if the arrest was without limit, although this fish species has been protected (Appendix II of CITES and KEPMEN 37/KEPMEN-KP/2013). This study was conducted to analyze the population density of napoleon wrasse and utilization status. The density of fish used snorkeling visual census method (UVC). To find out the status of the utilization used the frequency distribution of fish length followed by counting the exploitation rate. The analysis showed that the density of fish in the surrounding waters napoleon Sinjai (South Sulawesi) was low (1.8 individuals/ha). Of calculating the exploitation rate, indicated that napoleon fish populations in waters around Sinjai-South Sulawesi has been over eksploited. From these results it is suggested that napoleon fish trade is still allowed to follow the terms and provisions of the size of the export quota. Estimated napoleon fish export quotas should be based on the data of biology and population dynamics of the fish so that the fish napoleon natural reproduction can take place by the level of exploitation.

Abstract

Dolphins are one of the most interesting cetacean types included in family Delphinidae or known as the oceanic dolphins from genus Stenella sp. and Tursiops sp. Migration and abundance of dolphins are affected by the presence of food and oceanographic conditions. The purpose of this research is to determine the composition and distribution of dolphins in relation to the water quality parameters. Benefits of this research are expected to provide information on the relationship between distributions of the family Delphinidae cetacean (oceanic dolphins) and oceanographic conditions. The method for this research is descriptive exploratory, with models onboard tracking survey. Field observations were done in November 2015 and period of March-April 2016 outside and inside Savu Sea National Marine Park waters. The sighting of dolphin in November and March-April found as much seven species: bottlenose dolphin, fraser’s dolphin, pantropical spotted dolphin, risso’s dolphin, rough-toothed dolphin, spinner dolphin and stripped dolphin. The highest species distribution noted in the Savu Sea is spinner dolphin, pantropical spotted dolphin, rough-toothed dolphin and frazer’s dolphin. The existence of dolphins in Savu Sea is more related with sea surface temperature than others oceanographic parameters. This condition is suspected due to the influence of sea surface temperature to body temperature of dolphin especially for foraging activities. The habit of dolphin is more active around Sumba Island and Daratan Timor waters while in the evening the animal is usually going to Manggarai and Rote Ndao Islands waters to rest.
