Abstract

Research was aimed at determining toxicity of drilling cuttings towards Daphnia, revealed in LC50 96 hours, meaning that cuttings concentration cause 50% population of Daphnia within the period of 96 hour observation. LC50 96 hour is utilized for preliminary strategy of managing drilling cuttings. Static test was applied at the main bioassay experiment.  Mortality was as an indicator of toxicity.  Bioassay experiment refers to US-EPA (1991, 1996, 2002); Ziehl and Schmitt (2000).  Mortality and water quality fluctuation were observed at hours 2, 4, 6, 8, 24, 48, 72, and 96. Determination of LC50 96 hour was carried out by the method of Probit Analysis.  Manual count and software EPA Probit Analysis Version 1.5 were applied. LC50 96 hours cuttings towards Daphnia is 22.177 - 22,208 ppm.  This indicates that cuttings has almost non-toxic characteristic.  However, disposal of these cuttings needs oil content measurement.  If oil content meets regulation (? 10%), cuttings is allowed to be discharged to the surrounding terrestrial environment.

Abstract

The existence of horseshoe crabs Tachypleus gigas is currently on the threatened condition and its population status is also unclear. The objectives of this research were to asses the horseshoe crabs morphological characters and to identify based on molecular marker of Cytochrome Oxydase Subunit I (COI) gene. The samples were collected from five locations (Segara Menyan Subang, Ujung Kulon Banten, Tambak Lorok Semarang, Betah Walang Demak, and Kenjeran Surabaya) in October 2014 until June 2015. A total of 27 parameters for 62 individuals were used to determine connectivity and character identifier among populations. Data were tested using non-parametric analysis. While, the 5 individuals from each sites were used for molecular analysis including several stages of the DNA extraction, DNA electrophoresis, amplification and visualization of DNA fragments, and DNA sequencing. The results obtained based on morphological characters that T. gigas of Surabaya formed a unique group due to its body size (X1-X2 and X4-X16) was larger than the other 5 body parts (X22, X23, X26-X28) of Semarang, Demak, Subang, and Banten. According to molecular results, there were 650 bp conserve nucleotide sequences. Analysis using software MEGA 5.0 showed that there were 73 existence of specific nucleotide sites that can be used to distinguishes between T. gigas in-groups  and out-groups (T. gigas from Central Arabian Sea, T. tridentatus from Sweden, and Carcinoscorpius rotundicauda from USA).Keywords: horseshoe crabs, Java coast, morphology, identification molecular, CO1 gene.

Abstract. The oysters (Ostreidae) isone of economically important bivalves for urban community in Kuala Gigieng, Aceh Besar District. Presently, the quality and quantity of oyster is decreased over the years by intensive exploitation and water pollution. Therefore, theobjective of the present study was to analyze population structure and habitat condition of oystersin estuary area of Kuala Gigieng, Aceh Besar District, Aceh Province. The sampling was conducted at three locations during August to September 2013. The sampling locations were determined based on anthropogenic activities. A total of two genus of oysters were recorded during the study i.e Crossastrea with four species (C. gigas, C. iridescens, C. angulata, C. virginica) and and Ostrea edulis with one species (O. edulis). The highest density (>39 ind m-2)of oysters were found at undisturbed and less pressure environment. The distribution pattern of Ostreidae in the Kuala Gigieng water was clustered where frequency of occurrence wasin small class size of 24 mm to 37.20 mm with optimum harvested of 32.27 mm. The growth of the oysters was relatively slow as shown by the maximum length (Lmaks) that can only reach 37.91-72.81 mm within 0 to 3.42 years. Generally, oysters population structure and habitat conditions in Kuala Gigieng Water was declined over the yeras. Therefore, it is a crucially needed to plan a management strategy for oysters with regulation on fishing, shellfish farming and waste disposal regulation to ensure the oysters population remains sustain.Keywords : Environment factors; fishing, growth; Kuala Gigieng; Oyster; population structureAbstrak.

Abstract

ABSTRAKCahaya matahari merupakan salah satu faktor lingkungan terpenting baik secara langsung maupun tidak langsung bagi organisme fotosintetik perairan dalam menyediakan energi untuk diubah menjadi energi kimia dengan bantuan klorofil. Penelitian ini bertujuan untuk mengkaji hubungan antara ketersediaan cahaya matahari  dan konsentrasi pigmen fotosintetik di Perairan Selat Bali. Penelitian dilaksanakan pada pagi, siang dan sore hari pada lima stasiun penelitian di Perairan Selat Bali. Analisis korelasi kanonik digunakan untuk mengetahui hubungan antara ketersediaan cahaya matahari dan pembentukan pigmen fotosintetik. Hasil penelitian menunjukkan bahwa intensitas cahaya matahari (Y2) lebih berpengaruh terhadap pembentukan pigmen klorofil-b (Y1) dengan korelasi kanonik sebesar 0,4512 bilamana dibandingkan dengan pembentukan pigmen klorofil-a (Y1) dengan nilai korelasi sebesar 0,3982. Semakin tinggi pembentukan pigmen klorofil-b (Y1) dapat meningkatkan pembentukan pigmen karotenoid (Y1) secara signifikan dengan nilai korelasi kanonik sebesar 0,7419. Kesimpulan dari hasil ini, bahwa pigmen klorofil-b dan pigmen karotenoid akan terbentuk secara optimum pada intensitas cahaya rendah. ABSTRACTSunlight is one of the most important environmental factors both directly and indirectly for  photosynthetic organisms in providing energy to be converted into chemical energy with the help of chlorophyll. This study aims to examine the relationship between the availability of sunlight and the concentration of photosynthetic pigments in Bali Strait waters. The study was conducted in the morning, midday and afternoon at five research stations in the Bali Strait waters. Canonical correlation analysis was used to determine the relationship between sunlight availability and photosynthetic pigment formation. The results showed that the intensity of sunlight (Y2) had more influence on the formation of chlorophyll-b (Y1) pigments with canonical correlation of 0.4512 when compared with the formation of chlorophyll-a (Y1) pigment with a correlation value of 0.3982. The higher formation of chlorophyll-b (Y1) pigments can significantly increase the formation of carotenoid pigments (Y1) with canonical correlation values of 0.7419. From these results it can be concluded that chlorophyll-b pigments and carotenoid pigments will be formed optimally at low light intensities.

Abstract

This research was conducted at two different lakes in Jambi Province (Lake Sipin and Lake Teluk) to compare abundance of aquatic insect larvae (family: Chironomidae). Lake Sipin located close by the settlement and got many influences from anthropogenic activities. However, Lake Teluk got less anthropogenic disturbance. Both lakes have difference plants cover. The area around Lake Sipin was more open compared to Lake Teluk and it caused low transparency level in Lake Sipin. The transparency level of Lake Sipin was 58.62 cm whereas transparency level of Lake Teluk was 70.29 cm. The difference of this transparency level influenced Chironomidae Larvae abundance that was encountered. Larvae abundance which was found in Lake Sipin was 49 ind/m2, while larvae abundance of Lake Teluk was 374 ind/m2. The result showed that water transparency level, water colors and vegetation affected abundance of Chironomidae larvae. Keywords: abundance, chironomidae, water transparency
