Abstract

Natural production of sea cucumbers in decline, it is because of overfishing and use without any attempt for cultivation. There are several ways for the provision of seeds, one with a reproduction. Sea cucumbers can reproduce sexually and asexually. Sexual reproduction involves the sea cucumber sperm and egg cells, and that asexual reproduction through fission technique. Fission is the process of cleavage of the specimen the anterior, middle and posterior to the sea cucumber. The third part will grow into new individuals after each specimen was able to grow the missing part. The research was conducted on April-June 2012 at Bandengan, Jepara with the aim of analyzing the ability of the sea cucumber Holothuria fission reproduction impatiens and Holothuria atra and observe individual performance and survival of fission results from the fission through the stimulation of 1, 2, and 3 fission plane in sea cucumber Holothuria atra and Holothuria impatiens for the supply of seed. The method used was field experimental research. The results of this research showed stimulation of fission with 1 fission plane is faster than 2 fission plane and 3 fission plane. H. atra to fission faster than H. impatiens. On the stimulation of 2 fission plane, the anterior fission faster than the middle or posterior. The results of regeneration of the species H. impatiens are not able to regenerate. The posterior regenerate faster than the anterior and middle. The posterior regenerate faster than the anterior and middle. In general, sea cucumbers which were going through the stimulation of fission stage, wound closure phase, the stage of regeneration, which in turn will form the mouth and anus on the part of the divide.

Abstract

Kabupaten Pekalongan merupakan salah satu Kabupaten di pesisir utara Jawa yang berbatasan langsung dengan Laut Jawa. Seperti kebanyakan daerah di pesisir utara, Kabupaten Pekalongan tidak luput dari permasalahan banjir rob. Penyebabnya adalah kenaikan muka air laut (Sea Level Rise), penurunan tanah (land subsidence), dan tentu saja pemanasan global (global warming). Adanya banjir rob ini tentu sangat merugikan aktifitas manusia dan merusak berbagai infrastruktur pemukiman, industri, dan fasilitas-fasilitas lainnya. Tujuan dari penelitian ini adalah untuk memetakan tingkat kerawanan banjir rob terhadap pemukiman penduduk di Kabupaten Pekalongan, untuk kemudian dilakukan evaluasi terhadap Rencana Tata Ruang Wilayah Kabupaten Pekalongan Tahun 2010-2030. Parameter yang digunakan untuk menentukan tingkat kerawanan adalah ketinggian tanah, penurunan tanah, jarak dari bibir pantai, dan jarak dari sungai. Masing-masing parameter tersebut diberi bobot yang berbeda untuk kemudian dilakukan metode overlay atau tumpang susun dengan bantuan software ArcGIS 10. Hasil pengolahan data diketahui bahwa daerah rawan genangan rob di pesisir Kabupaten Pekalongan mencapai luas 586,294 Ha, yang meliputi 3 kecamatan. Sebagian dari wilayah rawan tersebut mengenai kawasan pemukiman, sehingga tata ruang pemukiman Kabupaten Pekalongan perlu dilakukan evaluasi untuk mengurangi dampak negatif banjir rob bagi masyarakat.

Abstract

Artemia is the most enthused nature feed in the fish and crustaceans hatchery operations, which causing the increase of Artemia’s demand and the prices. Hence, we need to develop the Artemia production through aquaculture. The first larvae development are the crucial time which causes a big risk of death and the feed compositions still contain many harmful bacteria that can reduce the production of Artemia. By giving MOS for Artemia, can be expected to reduce mortality rates and accelerate the growth. The purpose of this research is to investigate the percentage of using MOS against the survival rate and growth of Artemia. The additional feeding treatments were 0% (A), 1% (B), 3% (C), and 5% (D) of MOS added to the amount of phytoplankton. ANOVA is used for analysing the data, then continued with Polinomial Ortogonal test. The Results showed that different treatment significantly different to the survival rate and growth of Artemia. The best survival rate (39,50%) was from the C treatment, indicated by the high weight (753,37 μg), and longest growth length (9,0 mm). Water quality during the research is still in a decent range for the life of Artemia. This research can be concluded thah the best percentage of MOS given for bast survival rate growth by weight and length were 4,1%, 3,7% and 3,6% respectively.

Abstract

Knowledge of coral reproduction in Indonesian waters were divided into three groups, there are the spawning time which occurs in first transition season or before East season (January to April), the spawning time which occurs in second transition season or before West season (September-November), and the spawning time which occurs throughout the year. This study aims to predicted spawning time of Acropora by observe gonad maturity level during second transition season (September-October 2012) at Sambangan Island Karimunjawa Archipelago Jepara. The method used in this research was descriptive method. Distribution and composition Acropora were observed using Line Intercept Transect (LIT) method. Spawning time of Acropora was determined by presence or absence of gonad contents, and the maturity level of the gonads deferred to Hanafy et al. (2009). Gonad was examine in new moon phase, before full moon phase, and after full moon phase. The result show that distribution and composition of coral species Acropora at Sambangan Island in depth of 1-3 m was known 5 species of the stations I, 6 species at station II, and 8 species at station III with the highest cover composition at each station was a species A. formosa. Total 8 species Acropora were observe however only two species were found content of gonad. There were Acropora carduus and A. formosa. The gonad of coral A. carduus matured earlier than A. formosa. Gonad maturity of A. carduus occurred in September 2012 (new moon) and then gonad didn’t found in the phase before the full moon. Gonad maturity of coral A. formosa occured on the full moon phase in October 2012 and the phase after full moon the colony hadn’t contain gonads. Based on this information spawning of two species of Acropora likely occurred in different moon phase. Species of A. carduus has been spawned before the full moon phase and species A. formosa has been doing spawning after the full moon phase in October 2012.
