Abstract

REEF FISH COMMUNITY IN THE BATUANGUS NATURE PARK, MUNICIPALITY OF BITUNG, NORTH SULAWESI PROVINCEResearch was conducted at 4 point dive sites in TWA Batuangus and 1 tourist sites as a comparison site to see the condition of coral reef ecosystems that include coral cover and reef fish communities’ information. Live coral cover obtained generally show in moderate category (25 to 49.9%). Coral genus recorded in 33 transects genus were 27 genera of hard corals and 6 genus of soft corals. Reef fish recorded consists of 195 species of reef fish and 37 families. Locations in the TWA Batuangus which have relatively good conditions, is Batu Beach location where had higher abundance and biomass compared to other locations. Magic Rock seen better than that of TWA Batuangus, based from the condition of coral and targeted fish. This is most likely because the location of TWA Batuangus is the fishing area for the surrounding communities while Magic Rock is became one of the important diving spot in the Lembeh Strait. Reef fish community structure based on ecological indices are in unstable condition (H' were in low to moderate, E were depressed until labile and C were low). The similarity of reef fish species grouping Hall Batuangus separated with other sites because of the characteristics of the location in the form of semi-enclosed bays where the circulation of currents which do not enter into the bay which makes limiting the distribution of coral and fish.Keywords: abundance, biomass, Batuangus, reef fish community structure, wildlife nature.ABSTRAKPenelitian sebanyak 4 titik penyelaman di TWA Batuangus dan 1 lokasi wisata sebagai pembanding dilakukan untuk melihat kondisi ekosistem terumbu karang yang meliputi informasi tutupan karang dan komunitas ikan karang. Tutupan karang hidup yang didapatkan menunjukkan umumnya berada pada kategori sedang (25–49,9 %). Genus karang yang tercatat masuk di dalam transek sebanyak 33 genus yang terdiri dari 27 genus karang keras dan 6 genus karang lunak. Ikan karang yang dicatat/ditemukan dalam survei derah dangkal ini terdiri dari 195 species ikan karang yang termasuk dalam 37 famili. Lokasi di dalam TWA Batuangus yang memiliki kondisi relatif baik yaitu di lokasi Pantai Batu dimana memiliki kelimpahan dan biomassa terbaik dibanding lokasi lainnya. Lokasi pembanding Magic Rock sedikit lebih baik daripada TWA Batuangus, jika dilihat dari kondisi karang serta ikan target. Hal ini kemungkinan karena lokasi TWA Batuangus menjadi daerah penangkapan ikan bagi masyarakat sekitar, sedangkan Magic Rock yang menjadi salah satu spot penyelaman penting di Selat Lembeh. Struktur komunitas ikan karang berdasarkan indeks ekologinya berada dalam kondisi labil (H’ masuk rendah hingga sedang, E tertekan hingga labil dan C yang rendah). Kesamaan species ikan karang mengelompokkan site Hall Batuangus terpisah dengan site lainnya karena karakteristik lokasi yang berupa teluk semi tertutup dimana sirkulasi arus yang tidak masuk kedalam teluk yang menjadikan pembatas distribusi karang dan ikan yang ada di dalamnya.  Kata kunci: biomassa, Batuangus, kelimpahan, struktur komunitas ikan karang, Taman Wisata Alam.

Abstract

ABSTRACTIncreased sea surface temperatures due to global warming that occurred from the early to mid 2016 caused of coral bleaching in several locations in TWP Gili Matra. Observations of coral bleaching  obtained from coral colonies compotition affected by bleaching (50%), white (18%), death (1%) and was not affected (31%). These implications resulting decline in coral cover but not significant (F (1,013) = 0.333, p 0.05) from 23,43% ± 2,61 SE in 2012 to 18,48% ± 4,14 SE in 2016 and a significant decrease (P (58,06) = 3,8e-06) recruitment of coral (coral Juvenil) from 6,66 ind.m-1 ± 1,04 SE in 2012 to 1,41 ind.m-1 ± 0,16 SE in 2016. the other impact is a significant reduction (P(20.84) = 0,00053, p 0,001) the abundance of reef fish from 28.733,26 ind.ha-1 ± 3.757,89 SE in 2012 to 11.431,18 ind.ha-1 ± 702,53 SE in 2016 and a decline in the biomass of reef fish but not significant (F (0,58) = 0,46, P 0.05) from 506,56 kg.ha-1 ± 99,05 SE in 2012 to 438,41 kg.ha-1 ± 45,69 SE in 2016. The decline of coral recruitment resulted in the recovery of the affected areas bleaching becomes slow because of the juvenile new coral mostly dead. The second impact of bleaching is an abundance of fish decrease, indicating that is available only fish big size (adult) and very less of small fishes, including juvenile.

Abstract

Sebagian wilayah pesisir Pademawu dan sekitarnya, Pamekasan, dijumpai adanya air tanah payau hingga asin dengan pelamparan yang cukup luas. Tujuan penelitian ini adalah untuk memetakan sebaran air tanah asin hingga payau tersebut, baik pada akuifer dangkal maupun akuifer dalam dan juga untuk mengetahui penyebab keasinan air tanah tersebut. Sebaran air tanah asin dipetakan berdasarkan nilai daya hantar listrik (DHL) dengan kriteria tingkat keasinan sebagaimana ditetapkan oleh Panitia Ad Hoc Intrusi Air Asin Jakarta. Sedangkan penyebab keasinan air tanah dianalisa berdasarkan fasies hidrokimia dengan diagram Trilinier Piper. Hasil penelitian menunjukkan bahwa pada akuifer dangkal air tanah agak payau hingga asin dengan nilai DHL 15.000 µS/cm – 50.000 µS/cm dijumpai pada bagian Selatan Pademawu sepanjang pesisir pantai meliputi Padelegan, Jumiang, Tanjung, Manjungan dan Pademawu Timur. Sedangkan untuk air tanah dalam seluruhnya dalam kondisi tawar dengan nilai DHL 1500 µS/cm, berada pada bagian Utara dari daerah penelitian meliputi kecamatan Tlanakan, Galis, Pamekasan dan  Larangan. Berdasarkan nilai DHL bahwa daerah bagian Utara penelitian tidak terdeteksi adanya proses penyusupan air laut pada air tanah.INDICATION OF SEA WATER INTRUSION IN COASTAL PADELEGAN, PADEMAWU AREAIn the part of Pademawu coastal areas, Pamekasan, was found brackish groundwater that spreading progressively. The purpose of this study was to map the distribution of salt to brackish groundwater, both in the shallow aquifer and the deep aquifer and also to find out the cause of the salinity of the ground water. Salt groundwater distribution was mapped based on the electrical conductivity (EC) with a salinity level criteria as established by Panitia Ad Hoc Intrusi Air Asin Jakarta. While the causes of groundwater salinity were analyzed based on hydrochemical facies with Trilinier Piper diagram. The results showed that the shallow groundwater aquifers slightly brackish to salt with DHL value 15,000 μS / cm - 50,000 μS / cm found in the southern part of Pademawu along the coast include Padelegan, Jumiang, Tanjung, Manjungan and Eastern Pademawu. As for the groundwater at deep aquifer entirely in fresh condition with DHL value 1500 μS / cm, located in the northern part of the study area that include Tlanakan, Galis, Pamekasan and Larangan districts. Based on the DHL value, it shown that groundwater of the northern part of the study area was not affected by the sea water intrusion.Keywords: Electric conductivity, sea water intrusion, aquifer, Pademawu

Abstract

Fish is the potential protein source for human. People consumption of fish requires attention related to whether the fish is safe to consume. This research is aimed at finding kind of parasite attack Groupers (E. fuscoguttatus) and the prevalence and the infection level in the different farming location. The research method used that is by taking Groupers size between 10 cm - 35 cm as many  fish from all population in each location with the assumption of percentage the prevalence used was 10%. Sample then analyzed for amount and type of parasite attacked and determined level of prevalence and degree of parasite infection. Result showed the type of parasite attack Groupers are Anasakis sp., Diphyllobothrium sp., Caligus sp., Diplectanum sp., Ergasillus sp., and Argulus sp. The different location of farming didn’t influence the parasite prevalence degree in Groupers. It is known that in location 1 in Lamongan, the prevalence level is 60% and the amount of fish attacked is 12, while in location 2 which is in Situbondo regency the prevalence degree is 50% with 10 fish attacked. t-test result showed that the level of infection degree did not differ perhaps because of the water condition quality between two location was relatively similar and still in the normal category, and also farmers have known the farming techniques well. Key Words : Prevalence, Degree of parasite infection, Groupers
