Abstract Sea cucumbers are marine animals of the Holothuroidea Class that have ecological, health, and socioeconomic benefits. This study aims to determine the structure of the sea cucumber community on Harapan Island and East Penjaliran Island, Kepulauan Seribu National Park, Kepulauan Seribu Regency. Data collection was conducted in January 2020, where each island was divided into two stations, and each station was divided into three substations for data retrieval. The method is a quadratic transect method using a plot measuring 1x1 m. In each square plot, observations were made regarding the type and number of sea cucumbers found and water quality parameters, including salinity, temperature, pH, DO, and total organic matter. Observation parameters include diversity index, uniformity index, frequency, density, important value index, dominance, and sea cucumber distribution index. During the study, species found on Harapan Island include H. atra, H. scabra, H. leucospilota, Bohadschia marmorata, and Stichopus herrmanni. Meanwhile, species found on East Penjaliran Island include H. atra, H. leucospilota, H. coluber, H. pardalis, H. fuscocinerea, H. hilla, Bohadschia marmorata, Stichopus ocellatus, and Stichopus monotuberculatus. The most abundant and predominant species on both islands is Holothuria atra. The average diversity index on Harapan Island falls into the low category, while East Penjaliran Island is classified as medium. The dominance index of both islands is low and has a uniform distribution. Environmental conditions and sea cucumber exploitation affect the structure of sea cucumber communities on both islands.

Teripang Hitam (H. atra) merupakan jenis biota laut yang memiliki nilai ekologis dan ekonomis di perairan Taman Nasional Laut Karimunjawa. Tujuan penelitian ini adalah menganalisis hubungan panjang berat, faktor kondisi dan analisis perbedaan antara Holothuria atra(teripang hitam) yang hidup di zona perairan budidaya dan wisata dengan yang hidup di zona rehabilitasi. Pengambilan sampel teripang dilakukan pada siang hari di 3 stasiun zona budidaya dan wisata yaitu Menjangan Kecil, Menjangan Besar dan perairan sekitar Wisma Apung serta 1 stasiun zona rehabilitasi yaitu di Perairan Alang-alang. Pengamatan sampel teripang dilakukan secara sensus. Total sampel yang diperoleh di Alang-alang sebanyak 30 individu dengan kisaran panjang 13-43 cm, berat 49-514 g, Sampel di Menjangan kecil sebanyak 17 individu dengan kisaran panjang 9-26 cm, berat 20-260 g, sampel Menjangan Besar sebanyak 5 individu kisaran panjang 16-23 cm berat 66-193 g dan sampel di perairan sekitar Wisma Apung sebanyak 17 sampel kisaran panjang 14-28 cm berat 23-260 g. Pertumbuhan teripang di masing-masing perairan menunjukkan pola pertumbuhan allometrik negatif yang artinya penambahan panjang lebih cepat daripada penambahan bobot. Nilai faktor kondisi Fulton teripang hitam di Alang-alang 1,34, Menjangan Kecil 1,91, Menjangan Besar 1,89, serta perairan sekitar Wisma Apung 1,37, menunjukkan teripang hitam di perairan yang banyak pengunjung lebih gemuk daripada teripang hitam di Alang-alang yang sepi pengunjung, serta faktor kondisi berat relatif alang-alang 104,27, Menjangan Kecil 104,25, Menjangan Besar 105,59 dan Wisma Apung 108,22 masing-masing perairan semua diatas 100 menunjukkan perairan tersebut menyediakan surplus makanan yang cukup.  Black Sea Cucumber (H. atra) is a type of marine biota that has ecological and economic value in the waters of the Karimunjawa Marine National Park. The purpose of this study was to analyze the relationship length-weight, condition factor and analysis of differences between Holothuria atra (black sea cucumbers) that live in cultivation and tourism zones and those that live in rehabilitation zones. Sea cucumber sampling is conducted at noon in 3 stations of the cultivation and tourism zones, namely Menjangan Kecil, Menjangan Besar and the waters around Wisma Apung and 1 rehabilitation zone station in Alang-alang. Observation of sea cucumber samples is done by census. Total samples obtained in Alang-alang were 30 individuals with a range of length 13-43 cm, weight 49-514 g, sampel in Menjangan Kecil were 17 individuals with a range of length 9-26 cm, weight 20-260 g, sampel in Menjangan Besar were 5 individuals with a range of length 16-23 cm, weight 66-193 g, and last sampel in waters around Wisma Apung were 17 individuals with a range of length 14-28 cm weight 23-260 g. The growth of sea cucumbers in each waters shows a negative allometric growth pattern which means that the addition of the length is faster than the addition of the weight. Fulton’s condition factor values of black sea cucumber in Alang-alang 1.34, Menjangan Kecil 1.91, Menjangan Besar 1.89, and waters around Wisma Apung 1.37, shows that black sea cucumbers in the waters that many visitors are fatter than black sea cucumbers in the Alang-alang which deserted visitors, and the relative weight condition factors of Alang-alang 104.27, Menjangan Kecil 104.25, Menjangan Besar 105.59 and Wisma Apung 108.22 each of the waters above 100 indicates that these waters provide sufficient food surplus.

AbstractA strategy to circumvent the problem of multidrug resistant pathogen is consumption of functional food rich in anti-infectives targeting bacterial virulence or host immunity. The black sea cucumber (Holothuria atra) is a tropical marine sea cucumer species traditionally consumed as remedy for many ailments. There is a paucity of knowledge the anti-infectives capacity of H. atra and the underlying mechanisms involved. The objectives of this study were to utilize the Caenorhabditis elegans-P. aeruginosa infection model to assess the anti-infective properties of H. atra. We first showed the capacity of a H. atra extract and fraction in promoting survival of C. elegans during a customarily lethal P. aeruginosa infection. The same chemical entities also attenuate the production of several P. aeruginosa virulence factors and biofilm. Treatment of infected transgenic lys-7::GFP worms with H. atra fraction restored the repressed expression of lys-7, a defense enzyme, indicating improved host immunity. QTOF-LCMS analysis revealed the presence of aspidospermatidine, an indole alkaloid and inosine. Collectively, our finding shows that H. atra confers survival advantage in C. elegans against P. aeruginosa infection through inhibition of pathogen virulence and eventually, the restitution of host lys-7 expression.
