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).

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.
