Abstract

Penyakit karang adalah gangguan terhadap kesehatan karang yang menyebabkan gangguan secara fisiologis bagi biota karang. Penyakit karang dapat memberikan dampak buruk terhadap proses pertumbuhan karang hingga dapat menyebabkan kematian karang disuatu perairan. Dampak dari penyakit karang terhadap ekosistem terumbu karang sangat besar, selain mengakibatkan kematian karang dalam skala yang luas, penyakit karang juga berdampak pada berkurangnya tingkat keanekaragaman sumberdaya alam. Penelitian ini bertujuan untuk mengetahui dan menganalisis laju infeksi penyakit White Plague dan White Band Disease di perairan Pulau Tikus, Kota Bengkulu. Penelitian ini dilaksanakan pada bulan September-Oktober 2019 di Perairan Pulau Tikus, Kota Bengkulu. Metode yang digunakan dalam penelitian ini adalah metode survei, pengamatan dan pengukuran langsung di Lapangan. Hasil Penelitian ini didapatkan bentuk pertumbuhan yang terinfeksi penyakit White Plague di Perairan Pulau Tikus Kota Bengkulu adalah bentuk pertumbuhan karang Massive dan penyakit White Band Disease pada karang Acropora. Metode yang digunakan dalam penelitian ini adalah metode survei, pengamatan dan pengukuran langsung di lapangan.Laju infeksi penyakit White Plague di perairan Pulau Tikus Kota Bengkulu adalah 0,009 - 0,023 cm/hari. Laju infeksi penyakit White Plague mengalami kenaikan setiap minggu dengan rata rata laju infeksi 0,015 cm/hari dan nilai laju infeksi penyakit White Band Disease yang terdapat pada karang Acropora di Perairan Pulau Tikus, Bengkulu yaitu 0,013 cm/hari – 0,030 cm/hari. Rata – rata yang diperoleh yaitu 0,024 cm/hari. Nilai laju infeksi karang menandakan bahwa sebagian besar kerusakan terumbu karang diakibatkan oleh penyakit karang.THE RATE OF WHITE PLAGUE AND WHITE BAND DISEASE IN TIKUS ISLAND, BENGKULU CITY. Coral disease is a disorder of coral health that causes physiological disruption to coral biota. The coral disease can adversely affect the coral growth process until it can lead to coral death in a waterway. The impact of coral disease on coral ecosystems is very large. In addition to resulting in coral death on a wide scale, a coral disease also affects natural resources' reduced diversity. This research aimed to determine and analyze the White Plague and White Band Disease's infection rate in Tikus Island, Bengkulu City. The research was conducted in September-October 2019, located in Tikus Island Water, Bengkulu City. The methods used in this study are direct survey, observation, and measurement methods in the Field. This study obtained a form of growth infected with White Plague disease in the Waters of Tikus Island Bengkulu City. The infection rate of White Plague Disease in Tikus Island was 0.009-0.023 cm/day. The quality of the condition of White Plague disease increased every week with an average infection rate of 0.015 cm/day, and the rate of infection rate of White Band Disease found in Acropora coral in the Waters of Tikus Island, Bengkulu which was 0.013 cm/day – 0.030 cm/day.

Abstract

Bakteri yang hidup pada tanah mangrove bersifat halofilik yaitu mampu hidup pada lingkungan dengan kondisi kadar garam yang tinggi. Bakteri yang hidup pada zona yang ekstrim memerlukan protein yang tinggi untuk mempertahankan hidup dan dapat melakukan metabolisme, salah satunya dengan membentuk enzim terutama enzim ekstra seluler (enzim amilase, protease, selulase dan lipase). Tujuannya yaitu untuk mengisolasi dan menyeleksi bakteri penghasil enzim ekstraseluler. Metode yang digunakan adalah survey dan eksperimental terhadap isolasi bakteri dari tanah mangrove yang dikarakterisasi berdasarkan morfologi, pewarnaan gram, dan uji aktivitas enzim amilase dengan media amilum, protease dengan media skim milk, selulase dengan media Carboxy Methyl Cellulosed an lipase dengan media tween 80. Analisis data secara deskriptif kuantitatif. Terdapat tiga parameter yang diukur yaitu suhu, salinitas dan pH. Berdasarkan data penelitian ditemukan bahwa tanah mangrove yang ada di pantai Noelbaki menghasilkan 70 isolat bakteri penghasil enzim ekstra seluler. 33 isolat bakteri memiliki aktifitas enzim amilase, 20 isolat memiliki aktifitas enzim proteolitik, 56 isolat memiliki aktifitas selulolitik,10 isolat memiliki aktifitas lipolitik, sehingga total isolat yang memproduksi enzim ekstraseluler adalah 119 isolat, hal ini menjelaskan bahwa beberapa isolat memiliki kemampuan menghasilkan enzim multi-aktifitas atau mampu menghasilkan beberapa enzim.ISOLATION AND SELECTION OF BACTERIA PRODUCING EXTRACELLULAR ENZYMES ON MANGROVE LAND OF NOELBAKI BEACH. Bacteria living in the halofilic mangrove land are able to live in environments that are high salinity. Bacteria that live in the extreme zone require high proteins to sustain life and can metabolize, one by forming enzymes especially extra-cellular enzymes (amilase, protease, selulase and lipase). The aim was to isolate and select extra-cellular enzyme bacteria. This method was a survey and experimental against the insulation of mangrove land controlled by morphology, dyeing grams, and testing for amilase enzyme activity for amilum media, protease with skim milk, selulase with medium carboxy methyl cellulose and lipase in tween media. Quantitative descriptive analysis of data. Three parameters, measured temperature, salinity and ph. Based on research data, were found that mangrove soils located on the coast of noelbaki produced 70 insulations of extreme enzyme yielding bacteria. 33 bacterial isolates have activity in amilase enzyme, 20 isolates have protein activity, 56 isolates had activity cellulase enzyme, 10 isolates had activities lipase enzyme, that include 119 isolates which produced extra-cellular enzymes, which made it clear that some isolates had the ability to create a multi-activity enzyme.

Abstract

Fauna bentik (makrozoobentos) telah dianggap sebagai salah satu kriteria untuk menilai keberhasilan program restorasi mangrove. Kajian korelasi karakteristik lingkungan terhadap makrozoobentos di kawasan reboisasi mangrove Kepulauan Seribu telah dilakukan pada bulan Maret 2014. Hal ini bertujuan untuk mengetahui pengaruh yang diakibatkan oleh karakteristik lingkungan (parameter fisika kimia perairan) terhadap kepadatan makrozoobentosnya. Data biota makrozoobentos di kawasan reboisasi mangrove Kepulauan seribu dikumpulkan dengan membuat transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan, dimana pengamatan dilakukan di tiga stasiun (pulau). Sebanyak 6 famili dan 6 spesies makrozoobentos telah ditemukan di kawasan reboisasi mangrove Kepulauan Seribu. Komposisi dan kepadatan spesies tertingginya adalah Littoraria scabra. Karakteristik lingkungan yang diukur tidak begitu berbeda antar stasiun serta juga tidak melebihi ambang batas baku mutu. Semakin rendah konsentrasi salinitas dan DO, maka kepadatan makrozoobentosnya semakin tinggi, sedangkan semakin tinggi konsentrasi pH perairan, maka kepadatan makrozoobentosnya semakin menurun. Kemudian parameter suhu dengan kepadatan makrozoobentos tidak memiliki pengaruh.THE EFFECT OF ENVIRONMENTAL CHARACTERISTICS OF MAKROZOOBENTOS IN MANGROVE REFORESTATION AREA OF SERIBU ISLANDS, INDONESIA. Benthic fauna (macrozoobenthos) has been considered as one of the criteria for assessing the success of a mangrove restoration program. A correlation study of environmental characteristics of macrozoobenthos in the Seribu Islands mangrove reforestation area was carried out in March 2014. It aims to determine the effect caused by environmental characteristics (water physical-chemical parameters) on its macrozoobenthos density. Data of macrozoobenthos biota in the Seribu Islands mangrove reforestation area were collected by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland, where observations were made at three stations (islands). Six families and six macrozoobenthos species have been found in the Seribu Islands mangrove reforestation area. The composition and density of the highest species were Littoraria scabra. The measured environmental characteristics were not very different between stations and also did not exceed the quality standard threshold. The lower the salinity and DO concentration, the higher the density of macrozoobenthos, while the higher the concentration of water pH, the lower the density of macrozoobenthos. Then the temperature parameters with macrozoobenthos density had no effect.

Pengamatan proses pembuatan ikan asin dan uji organoleptik menggunakan angket dan pengamatan langsung. Uji organoleptik ikan asin meliputi kenampakan, rasa, bau, tekstur, dan jamur. Hasil penelitian menunjukkan bahwa proses pembuatan ikan asin di Desa Galo-Galo meliputi pembuangan bagian ikan yang tidak digunakan (sisik, isi perut dan insang), dicuci, dibilas, diberi garam, direndam, dicuci kembali, dan dijemur. Hasil uji organoleptik ikan asin dari Desa Galo-Galo menunjukkan bahwa ikan layak dikonsumsi karena memiliki nilai organoleptik >7.SALTED FISH PROCESSING AND ORGANOLEPTIC TESTING AT THE GALO-GALO VILLAGE OF PULAU MOROTAI REGENCY. Traditional fish processing is a form of processing that is mostly done by fisherman especially in the village of Galo-Galo South Morotai District. Salted fish is very popular with the community and even made a souvenir typical of Morotai. This salted fish is usually sold to the traditional markets of Pulau Morotai and the surrounding area. This study aims to determine the process and organoleptic of salted fish in the Galo-Galo village, Pulau Morotai regency. This research was conducted from July to August 2019 in Galo-Galo village Pulau Morotai. To observe the process of making salted fish, and organoleptic, the researcher used a questionnaire and direct observation. Here’s the process of making salted fish: first of all, clean your fish well and remove from stomach contents and gills then rinse them and rub them with plenty of salt. Finally, hang the fish in the sun. Organoleptic test of salted fish from this village was very suitable for consumption because the value of organoleptic was very good (>7).

Abstract

Ekosistem terumbu karang adalah ekosistem laut yang sangat rentan oleh kerusakan lingkungan. Terumbu karang di perairan Bilik, Taman Nasional Baluran merupakan contoh ekosistem terumbu karang yang mengalami ancaman kerusakan lingkungan akibat perubahan iklim dan aktivitas manusia. Salah satu metode yang dapat digunakan untuk memonitor kesehatan terumbu karang adalah dengan melihat kelimpahan megabentos dalam ekosistem terumbu karang. Oleh karena itu, penelitian ini memiliki tujuan untuk mengetahui kesehatan ekosistem terumbu karang dengan melihat kelimpahan megabentos di perairan Bilik, Taman Nasional Baluran. Metode yang digunakan dalam inventarisasi megabentos adalah dengan Benthos Belt Transect dan analisis video di Blok Sijile dan Blok Jeding di Perairan Bilik. Hasil pengamatan menunjukkan bahwa di Blok Sijile tidak ditemukan ekosistem terumbu karang dan megabentos. Sementara itu di Blok Jeding ditemukan ekosistem terumbu karang dengan megabentos berupa bulu babi dan bintang laut biru. Kelimpahan bulu babi di dan bintang laut biru adalah 0-0,14 individu/m2. Kondisi tersebut menunjukkan bahwa kesehatan ekosistem terumbu karang di Blok Jeding perairan Bilik Sijile masih baik, namun perlu mendapat perhatian khusus karena sebagian area terumbu karang mengalami pemutihan akibat aktivitas perikanan yang tidak ramah lingkungan.MEGABENTHOS ABUNDANCE AS CORAL HEALTH INDICATORS IN BILIK WATERS, BALURAN NATIONAL PARK, INDONESIA. Coral reef ecosystems are marine ecosystems that are prone to environmental damage. Coral reefs in Bilik waters, Baluran National Park, are examples of coral reef ecosystems that are threatened by environmental damage due to climate change and human activities. One of the methods for health monitoring of coral reefs is by looking at the abundance of megabenthos in coral reef ecosystems. Therefore, this study aims to determine the health of coral reef ecosystems by looking at the abundance of megabenthos in Bilik waters, Baluran National Park. We used Benthos Belt Transect and video analysis to identify the spatial distribution and number of megabenthos in Sijile Block and Jeding Block, Bilik waters. The results showed that in Sijile Block, there were no coral reef neither megabenthos ecosystems. Meanwhile, in Jeding Block, there was a coral reefs ecosystem with megabenthos in the form of sea urchins and blue starfish. The abundance of sea urchins and the blue sea star in Jeding Block was about 0-0.14 individual/m2. These conditions indicate that the health of the coral reef ecosystem in Jeding Block, Bilik waters was still in good condition, even though it still needs special attention related to coral bleaching as a consequence of fisheries activities that are not environmentally friendly.

Abstract

The purpose of this study was to determine the level of diversity and genetic relationship of Panulirus versicolor lobsters in Cenderawasih Bay and Lombok waters based on the cytochrome oxidase I (COI) gene. The results showed the level of genetic diversity of the two populations was very high and generally did not differ greatly between populations. We identified 6 haplotypes for P. versicolor lobster populations from Cenderawasih Bay and 7 haplotypes for P. versicolor lobster populations from Lombok waters. Network analysis shows that several P. versicolor lobster individuals from the Cendeawasih Bay and Lombok waters had similar haplotypes. The population of Cenderawasih Bay with Lombok waters was closely related to the average genetic distance value P-distance 0.005 (s.d 0.001) and the results of phylogenetic tree reconstruction showed that the two populations of P. versicolor lobsters form a monophyletic clade (close relatives).
