Abstract

Abstrak. Penelitian ini bertujuan untuk mengetahui karakteristik habitat dan pola pertumbuhan kepiting kelapa (Birgus latro) di Takome Pulau Ternate dan Idamdehe Kecamatan Jailolo Propinsi Maluku Utara. Penelitian ini dilaksanakan pada bulan April-Juli 2014. Data yang dikumpulkan adalah tekstur substrat dengan metode pipet, penentuan kandungan nitrat danfosfat tanah dengan metode spektofotometer, pengukuran panjang + rostrum (cp+r) kepiting kelapa dan pola pertumbuhannya. Selain it juga diukur suhu udara, suhu lubang dan kelembaban udara. Hasil penelitian menunjukkan bahwa Idamdehe memiliki karakteristik pantai yang curam, bahkan di beberapa lokasi penangkapan sangat terjal, sedangkan  di lokasi Takome Pulau Ternate memiliki karakteristik pantai yang lebih landai. Tekstur substrat di lokasi Takome Pulau Ternate terdiri atas pasir (55,76 %), debu (18,4%) dan liat (25,84%) dan Stasiun Idamdehe memiliki tekstur pasir (49,17%), debu (25,61%) dan liat (25,22%)dankandungan bahan organik substrat (Total N) di Takome adalah 0,31% dan total P adalah 0,09% sedangkan di Idamdehe Total N adalah 0,19% dan Total P 0,02%. Suhu udara di lokasi Idamdehe berkisar 26-280C dan di Takome 27-280C. Kelembaban udara 73%-98% di Idamdehe dan 71%-90% di Takome. Parameter lingkungan berupa suhu udara, kelembaban udara, tekstur substrat dan kandungan bahan organik di kedua lokasi penelitian mendukung kehidupan kepiting kelapa di habitat alaminya. Pola pertumbuhan kepiting kelapa di kedua lokasi Idamdehe adalah allometrik negatif.Kata kunci: Karakteristik habitat, Idamdehe, Takome, Birgus latro, isometrik, allometrik negatifAbstract. This objectives of the present study were to evaluate the habitat characteristics and growth patterns of the coconut crabs in Takome and Idamdehe waters North Maluku Province. This study was conducted during April-July 2014. The collected data were the substrate texture, nitrate and phosphate contents of soil using spectrophotometric method, length + rostrum (cp+r) of coconut crabs and the growth patterns. In addition, the air temperature, hole temperature and humidity were also recorded during the study. The results showed that Idamdehe waters has precipitous coast, indeed very precipitous in several catching locations, while Takome waters in Ternate Island has sloping coast. The substrate texture of Takome waters in Ternate Island consisted of sands (55.76%), dusts (18.4%) and clays (25.84%), while Idamdehe waters has the substrate texture that consisted of sands (49.17%), dusts (25.61 %) and clays (25.22%). As for organic matter contents of the substrate, Takome waters has 0.31% in total N and 0.09% in total P, while Idamdehe waters has 0.19% in total N and 0.02 % in total P. The air temperature in Idamdehe waters ranged between 26-280C and in Takome waters ranged between 27-280C. Air humidity in Idamdehe waters was 73%-98% and in Takome waters was 71%-90%. The environmental parameters such as temperature, humidity, substrate texture and organic matter content in both locations are suitable for coconut crab growing. The growth pattern of coconut crabs in Idamdehe and Sulamadaha waters were allometric negative pattern.Keywords: Habitat characteristics, Idamdehe, Takome, Birgus latro, isometric, negative allometric.

Abstract

Abstract. The research was conducted in Kotok Besar, Karya and Pramuka Islands, Seribu Islands, Jakarta Province from May to July 2013. The aims of the research were to examine the percent cover, composition of vegetation and estimation of seagrass leaves biomass. The squares transect (0.25 m2) was utilized to calculate the seagrass percent cover data. Seagrass data were converted to total cover and biomass formula to estimate the seagrass leaves biomass. The result of our study showed there are 4 species of seagrass occurred in Kotok Besar Island, while 6 species were recorded in Karya and Pramuka Islands. Cymodocea rotundata had the higher value of seagrass cover percentage in Kotok Besar, Karya and Pramuka Islands, while the lower values were Halodule uninervis and Halophila ovalis.  In addition, the highest value of seagrass leaves biomass from those islands is Enhalus acoroides and the lower value was Halophila ovalis inKotok Besar and Pramuka Islands, and Halodule uninervis in Karya Island.Keywords: Composition of vegetation, estimated of biomass, seagrass, Seribu Islands  Abstrak.  Penelitian ini dilakukan di Pulau Kotok Besar, Karya dan Pramuka Kepulauan Seribu-Provinsi Jakarta mulai Mei sampai Juli 2013. Tujuan dari penelitian ini adalah mengetahui komposisi vegetasi lamun dan estimasi jumlah biomassa daun lamun di pulau Kotok Besar, Karya dan Pramuka kepulauan Seribu-Provinsi Jakarta. Penelitian ini dilakukan dengan mengguakan transek kuadrat (0,25 m2) untuk mengetahui persentase penutupan lamun. Data lamun yang diperoleh dikonversikan pada persamaan total penutupan dan estimasi biomasa untuk mengestimasi biomassa daun lamun. Hasil dari penelitian, terdapat 4 jenis lamun yang diperoleh di pulau Kotok Besar dan 6 jenis di pulau Karya dan Pramuka. Persen penutupan tertinggi pada pulau Kotok Besar, Karya dan Pramuka adalah jenis lamun Cymodocea rotundata, sedangkan yang terendah dari masing-masing pulau adalah Halodule uninervis dan Halophila ovalis secara berurutan. Estimasi biomassa daun lamun dengan nilai tertinggi adalah Enhalus acoroides dari ketiga pulau dan terendah adalah Halophila ovalis untuk pulau Kotok Besar dan Pramuka, dan Halodule uninervis untuk pulau Karya.Kata kunci: Komposisi vegetasi, estimasi biomassa, lamun, Kepulauan Seribu

Abstract. The objective of the present study was to analyze the morphometric variationsof five predominant fish species caught in Lake Aneuk Laot, Sabang City,Weh Island.The study was conducted in December 2015 to January 2016. The survey method was used in this study. The fish target were Nile tilapia (Oreochromis niloticus), tilapia (O. mossambicus), snakeskin gourami (Trichopodus pectoralis), giant gourami (Osphronemus goramy) and snakehead (Channa striata). The fish samples were catched using gillnets. The fish sample were analyzed for traditional and truss network morphometrics. The results showed that there is closed morphological relationship between Nile tilapia and tilapia, and between snakeskin gourami and giant gourami, while the snakehead fish was discriminated apart from the two previous groups.Keywords: Morphometric Nile tilapia, tilapia, snakeskin gourami, giant gourami, snakehead fish, Weh Island Abstrak.

Abstract. The aims of this research was to examine the water quality parameters and plankton abundance and its relationships in the Southwestern of Indian Ocean. This is a quantitative descriptive research. Planktons were sampled using plankton net, and water samples were taken using Conductivity, Temperature, Depth (CTD) where the water samples colleted in the Nansen Bottle No. 1 (surface water) at seven sampling stations. The results showed that there were 25 species of planktons belonging into seven classes, i.e., Bacillariophyceae, Ciliate, Crustacea, Cyanobacteria, Dinophyceae, Flagellata, and Maxillopoda. The highest value of abundance of plankton was found at station 6 with 7255 ind. L-1, the value of diversity index of plankton was at moderate category,  and there was no predominant species was occurred in the community. Bivariate correlation analysis results of Person's showed that the temperature and Dissolved Oxygen (DO) were positively correlated to the plankton abudance, while pH, conductivity, TDS, salinity were negatively correlated with abundances of plankton.Keywords: Abundance of plankton, linkages, water quality, Indian Ocean of Southwestern Abstrak.
