Black sea cucumber or Lollyfish are trade name for Holothuria atra, one species of family Holothuriidae abundance in Jepara waters, especially in Panjang Island.  They inhabit on the seabed, in shallow waters on reefs and sand flats or in Seagrass meadows. Beside reproduce sexually, H. atra also do fission (biology), i.e. able to reproduce asexually by transverse fission. Monthly survey has been conducted for three months to determine frequency of fission among H. atra population in Panjang Island waters. In total 891 individu of H. atra inhabit in seagrass meadow mixed with rubble were examimed. In fissiparous sea cucumber, transverse fission are followed by regeneration and in this research identified from external observations. The fission state was divided into three category, i.e. closed wound (Category 1), little regeneration either posterior or anterior part (category 2), moderate regeneration either posterior or anterior part (category 3).   The result showed that the fission frequency was highest during end of rainy season in April (13,21%) and decreased during May (4,61%) and June (4,86%). Body regeneration seem happened fast, since the new individu sea cucumber at category 1 was low but high as category 3. The regeneration were related with the condition of environment.

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.

ABSTRAKPadang lamun memiliki peran penting dalam suatu ekosistem perairan dangkal (mangrove, lamun dan terumbu karang). Namun kegiatan pembangunan di wilayah pesisir yang terus meningkat telah mengakibatkan kerusakan padang lamun yang hampir terjadi di seluruh perairan Indonesia. Saat ini informasi terkait dengan keanekaragaman spesies, kondisi lamun, dan luasannya khususnya di perairan timur Indonesia masih kurang. Tujuan penelitian ini yaitu memberikan informasi keanekaragaman spesies, kondisi padang lamun dan luasannya. Metode yang digunakan yaitu mengumpulkan data primer hasil kajian sejak 2005-2016 serta data sekunder dari beberapa sumber data hasil pemantauan kesehatan terumbu karang dan ekosistem terkait (lamun) pada program pemulihan dan pengelolaan terumbu karang (Coremap)-CTI 2015-2016. Identifikasi spesies lamun berdasarkan pada McKenzie (2003), pengambilan data dan analisa kondisi lamun mengacu pada buku panduan pemantauan padang lamun dan berdasarkan KMNLH (2004) no. 200. Hasil identifikasi spesies lamun ditemukan 10 dari 12 spesies lamun yang ada di perairan Indonesia. Kondisi padang lamun di perairan timur Indonesia dikategorikan‘baik’ (43%),’sedang’ (50%) dan ‘jelek’ (7 %) dengan luas padang lamun saat ini yaitu 146.283,68 ha.                                                    ABSTRACTSeagrass meadows has an important role at the shallow waters ecosystems (mangrove, seagrass and Coral reef). Development activities in the coastal area which is on still the rise has resulted in damage of the seagrass meadow in Indonesia waters. Current information related to biodiversity of seagrass, condition and extent of area in the eastern waters of Indonesia is still lacking. The goal of the research is to provide information about biodiversity, condition of seagrass meadows and extent of seagrass. The methods used the primary data collection of the result of study since 2005-2016 and secondary data collection from the Reef Health Monitoring and related ecosystem (seagrass) activity in the Coral reef Management and Rehabilitation Programme (Coremap)-CTI 2015-2016. Seagrass identification based on McKenzie (2003), collection of data and analyze of seagrass condition refer to the guide book monitoring of seagrass and KMNLH (2004) no.200. The Results of the study is found 10 of the 12 species of seagrass have found in the Indonesia waters. The condition of seagrass meadows are generally 'good’ (43%), ‘medium’ (50%) and 'poor’ (7%). Extent of seagrass area currently is 146,283.68 ha.

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.

The so called “black sea cucumber” are found in Indonesia as several species including Holothuria atra, H. leucospilota, H. coluber, H. excellens and H. turriscelsa. The local community of Wainure village near Pombo Island in central Maluku had reported that most sea cucumbers inhabiting the island are the black sea cucumbers or locally known as “teripang hitam.” They are occasionally consumed but not exploited excessively by the locals. The goals of this study are to identify the species of black sea cucumbers inhabiting Pombo Island and map their distribution to understand the microhabitats of black sea cucumber. Two field surveys conducted in March and April 2014 collected more than 550 individuals of black sea cucumbers that belong to two species Holothuria (Halodeima) atra Jaeger, 1833, and Holothuria (Mertensiothuria) leucospilota Brandt, 1835. Furthermore, distribution maps of these two species show that they are found only along the SE to SW coast of the island. Such distribution may relate to the availability of marine vegetation, as well as boulders and stones that provide shelters to the organism. The distribution maps also show that H. atra has a wider distribution than H. leucospilota in Pombo Island. This may be due to the semi-cryptic habit of H. Leucospilota’s (i.e. hiding its posterior body under rocks or crevices), making its distribution restricted to areas that provide ample shelters.
