Morfometri, Pemijahan, dan Indeks Kematangan Gonad Teripang Komersial di Perairan Pulau Nyamuk, Karimunjawa

Sea cucumbers are marine organisms that live in coral reef ecosystem habitats and their associations. Sea cucumbers have been used by communities as food, cosmetics and traditional medicine in various countries. The benefits and high economic value of sea cucumbers make fisheries activities occured massively and continuously. Sea cucumbers were large commodity from Indonesian waters. However, until now it has not received proportional attention. The lack of information on morphometry, spawning in various regions has made the commodity of sea cucumbers decreased. This research was conducted to determine the character of commercial sea cucumber commodities in Pulau Nyamuk, to the occurrence of spawning based on the moon phase. This research was conducted in September - November 2020. This research method uses an analysis approach of gonadal maturity index in determining the spawning of sea cucumbers. The results showed that commercial sea cucumbers in Pulau Nyamuk were Pisang (Holothuria sp.) and Gamat (Stichopus sp.) Sea cucumber. This sea cucumber weighs 300-690 grams wet. Sea Cucumbers, Pisang and Gamat tend to have high IKG values in the new moon phase with IKG index values >10%. Teripang merupakan organisme laut yang hidup pada habitat ekosistem terumbu karang dan asosiasinya. Teripang telah dimanfaatkan oleh masyarakat di sekitar pantai sebagai bahan makanan, kosmetik serta obat tradisional di berbagai negara. Manfaat serta nilai ekonomi teripang yang tinggi membuat aktivitas pemburuan terjadi secara masif dan terus menerus. Teripang juga merupakan komoditas besar yang berasal dari Perairan Indonesia. Namun hingga saat ini belum memperoleh perhatian yang proporsional. Minimnya informasi mengenai morfometri, pemijahan di berbagai daerah membuat komoditas teripang turun secara drastis. Penelitian ini dilakukan untuk mengetahui karakter komoditas teripang komersial di Pulau Nyamuk, hingga terjadinya pemijahan berdasarkan fase bulan. Penelitian ini bulan September - November 2020 di Perairan Pulau Nyamuk Kecamatan Karimunjawa, Kabupaten Jepara. Metode penelitian ini menggunakan pendekatan analisis indeks kematangan gonad dalam menentukan pemijahan teripang. Hasil penelitian menunjukkan bahwa teripang komersial di Pulau Nyamuk adalah jenis teripang Pisang (Holothuria sp.) dan Gamat (Stichopus sp.). Teripang ini mempunyai berat 300-690 gram basah. Teripang Pisang dan Gamat cenderung mempunyai nilai IKG yang tinggi pada bulan baru dengan nilai indeks IKG >10%.

AbstractSea cucumber Holothuria sp. is a marine biota that has economic value. The rearing activity of sea cucumbers is still limited to the have bay or strait areas with relatively calm coastal. This research aimed to determine the effectiveness of two types of pen‒culture system for sea cucumber rearing to the influence of ocean waves and currents. This research was done from February to July 2017 in the coastal of Rat village, Southeast Maluku Regency. The two of cultivated containers tested were a conventional pen‒culture (treatment A) and engineered pen‒culture (treatment B). A total of 30 individuals sea cucumber seeds sized 4‒6 cm were released at each pen‒culture. Survival rate and water quality were also calculated as supporting data. Observation of endurance and clearance of pen‒culture was done every two weeks. The result of visual observation showed that conventional pen‒culture treatment A was more quickly damaged and it was more damaged compared to engineered pen-culture treatment B.Through t‒test we got T count (1.065) < Ttable (6.313) for survival and T count (0.084) < Ttable (1.782) for growth. The result means that treatment A and treatment B have the same effect onsurvival rate and growth of sea cucumber. The results showed that treatment B was better applied to more open waters than treatment A.

Abstract. Aulia ED, Hadi TA, Utama RS. 2021. Sponge community (Porifera) in coral reef ecosystem in Sabang, Aceh Province, Indonesia. Biodiversitas 22: 3394-3402. Sponges are one of the most influential benthic organisms in coral reef ecosystems. Many studies about sponge communities have been carried out globally, from tropical to temperate regions. In Indonesia, however, sponge communities have not been adequately observed, especially their diversity and interaction with habitats. Sabang, a developing city located in the northwest of Indonesia, has a lack of information about benthic communities and no reports about sponges. This study investigated the sponge community (species richness, coverage, and morphological characters) and the interactions, both within sponges and with corals and substrates, in Sabang. The study found that the sponge richness (species and morphology) and coverage are categorized as poor, having only 24 species with seven morphologies, and coverage of 1.79 ± 1.03% (SE). The interaction analyses showed significant relationships occur among sponge variables but not between sponges and corals, nor between sponges and their substrates. These results could be attributed to the hydrodynamic-related stresses in Sabang, which are likely influenced by exposure to the open ocean, a condition that is less favorable to diversity and interaction. It is necessary to regularly monitor the condition of benthic communities in Sabang in order to better understand their stable state and detect any change over time.

Activity of Microtus pennsylvanicus was recorded as the number of crossings per day over a sand transect during four consecutive summers. Appropriate samples were selected to test the effects of both moon phases and moonlight on activity. Initially the results of tests comparing new moon to full moon phases showed that the voles were more active during new moon in only 3 of 10 discreet paired samples tested. However, when the effects of sampling sequence, phenology of population growth, date at which moon phases occurred, and, finally, the effect of climate were all considered as factors which could have affected the above results, it seemed reasonable to conclude that the new moon phase tended to be associated with higher activity. To establish if moonlight by itself, independent of phases, was a factor affecting the activity, tests were made during brightest and darkest nights of the lunar month and results indicated that moonlight did not affect the differences in activity found in the moon phase tests.

La observación de las fases lunares para realizar actividades agrícolas, es una costumbre de muchas culturas alrededor del mundo. Sin embargo, existen pocos estudios científicos relacionados con este tema. El objeto de esta investigación fue determinar la influencia de las fases lunares sobre el rendimiento del maíz. Para ello se consultó a 45 productores de 19 comunidades de la Región Autónoma Atlántico Sur (RAAS), sobre el uso de las fases lunares para la siembra. Además, se estableció un experimento utilizando un diseño de bloques completamente al azar con cuatro repeticiones por cada fase lunar (16 parcelas en total). Se midió el porcentaje de germinación, el crecimiento y rendimiento del cultivo. Los datos fueron analizados utilizando el programa InfoStat versión 2010. Los resultados reflejan que la germinación de las semillas presentó diferencias estadísticas significativas, siendo mayores en parcelas sembradas en las fases de cuarto creciente y luna nueva. La variable altura, largo y peso de mazorca, no presentaron diferencias significativas según fase lunar. En la variable diámetro del tallo se encontró diferencia significativa; las plantas sembradas en luna nueva presentaron el mayor diámetro. El daño causado por enfermedades y herbívoros presentó un resultado variable para las cuatro fases lunares. El peso promedio del maíz sembrado en la fase de luna nueva fue mayor que en las otras fases, contrario a la creencia popular de los productores de la región. SUMMARY Observation of the moon phases for agricultural activities is a custom in many cultures around the world. However, there are few scientific studies related to this topic. The purpose of this research was to determine the influence of moon phases on corn yields. In order to achieve this goal, 45 producers were consulted from 19 communities in the South Atlantic Autonomous Region (RAAS), regarding the use of the moon phases for sowing. Besides, an experiment was made using a block design completely at random using four replicates for each moon phase (16 plots in total). We measured the percentage of germination, the growth and yield of the crop. Data were analyzed using InfoStat 2010 version. The results show that the seed germination presented significant statistical differences, being higher in plots planted in the first quarter and new moon phases. The variables such as height, length and cob weight, showed no significant differences according to the moon phase. Regarding the stem diameter, significant differences were found, in which the plants sowed on new moon had the biggest diameter. The damage caused by diseases and herbivores presented an outcome variable for the four moon phases. The average weight of corn sowed in the new moon phase was higher than in the other phases, contrary to the producer’s popular belief in the region.

Penempatan reef ball di perairan Teluk Buyat dan sekitarnya telah dilakukan pada tahun 1999 oleh PT. Newmont Minahasa Raya. Tujuan penempatan reef ball untuk membangun habitat berbagai biota yang berasosiasi dengan karang sehingga dapat meningkatkan populasi ikan ekonomis penting. Kehadiran ikan karang pada reef ball sangat penting secara ekologis dan ekonomis. Penurunan kualitas terumbu berarti hilangnya nilai ekonomi barang dan jasa, serta hilangnya jaminan makanan dan pekerjaan untuk masyarakat pesisir, yang umumnya hidup dalam kemiskinan. Secara keseluruan, komposisi spesies ikan yang ditemukan di reef ball terdiri dari 19 famili, 34 genus, 50 spesies dan 290 individu, yang tertinggi dihuni oleh jenis dari famili Mullidae. Seiring dengan bertambahnya waktu dan usia reef ball, beberapa spesies terlihat sudah menetap seperti Lutjanus kasmira, dan beberapa spesies dari famili Acanthuridae. Keberadaan reef ball membantu terbentuknya ekosistem terumbu karang yang baru dan meningkatkan kesuburan perairan, sehingga lebih meningkatkan keberadaan komposisi ikan karang, yang pada akhirnya meningkatkan pendapatan nelayan dari hasil tangkapan ikan karang.Kata kunci: Reef ball, karang batu, ikan karang Distribution of Coral Reefs and Fish in Buyat Bay Area Reef Ball Southeast Minahasa Regency The placement of reef ball in Buyat Bay and surrounding areas have been carried out since 1999 by PT. Newmont Minahasa Raya. The goal of this placement was to build a habitat for many biota associated with reef thus may improve economically important fish populations. The presence of reef fish on the reef ball is indispensable ecologically and economically. Furthermore, the degradation of reefs might cause the disappearance of economic value of goods and services, as well as the disappearance of food security and employment for coastal communities, who generally live in poverty. Overall, the composition of fish species found in the reef ball consists of 19 families, 34 genera, 50 species and 290 individuals, the highest inhabited by species of the family Mullidae. As time went by and the increase of reef ball age, some species seem have settled down such as Lutjanus kasmira, and several species of the Acanthuridae family. In addition, the presence of reef ball helps the formation of a new coral reef ecosystem and increase the fertility of waters, therefore enhancing the presence of reef fish composition, which might increases the income of fishermen.

It is well established that the lunar cycle can affect the behaviour of nocturnal animals, but its potential to have a similar influence on diurnal species has received less research attention. Here, we demonstrate that the dawn song of a cooperative songbird, the white-browed sparrow weaver ( Plocepasser mahali ), varies with moon phase. When the moon was above the horizon at dawn, males began singing on average 10 min earlier, if there was a full moon compared with a new moon, resulting in a 67% mean increase in performance period and greater total song output. The lack of a difference between full and new moon dawns when the moon was below the horizon suggests that the observed effects were driven by light intensity, rather than driven by other factors associated with moon phase. Effects of the lunar cycle on twilight signalling behaviour have implications for both pure and applied animal communication research.

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.
