Abstract

Glutathione is intracellular low molecular weight thiols as detoxification agent in most marine microalgae. The short continuous culture was used to describe diurnal cycle of intracellular glutathione during light: dark period. The result showed that glutathione tend to follow light period and minimum levels at the end of dark period. Cysteine exhibited twofold diurnal variations, maximum levels at the early dark period. Those may prove that glutathione may have an important role as an antioxidant in marine phytoplankton.

Abstract

Marine biodiscovery or bioprospecting activity is a search for marine products derived from marine biodiversity that can be developed for various industrial needs. Including in this activity is the process of identifying chemical compounds made by biological organisms which is often called natural product discovery. Indonesia, well known as a mega-diversity country, is one of the world hot sport of marine biodiversity. The richness of biodiversity is claimed as mirror of the richness of the chemical compounds, therefore, Indonesian waters might be rewarded with variety of chemical compounds thought to be an endless source of novel drugs and drug leads for pharmaceutical use. Up to 2007, at least 77 new compounds from 14 sponges and 19 new compounds from non-sponge organisms with pharmacological potential have been identified from Indonesian waters. To make this richness potentials becoming real in economic value, many factors should be considered. The bioactive is produced in small quantity, and the lengthy process from discovery step of a novel compound to the preclinical and clinical trials step is usually becoming a problem. Mari culture might be one among methods that can be developed in Indonesia to overcome the degradation hazard of marine resources. Conducive environment for investments, and improvement of technology on marine bioactive production through mariculture are factors to be improved to initiate and develop a sustainable biotechnology industries in Indonesia.

Abstract

The purpose of this research was to determine quality of smoked catfish (Arius thalassinus) using paddy chaff and coconut shell liquid smoke. The fish were divided into two groups; then processed using paddy chaff and coconut shell liquid smoke. All of the smoked catfish samples were subjected to chemical, microbiological and organoleptic analyses. The result indicated that moisture content of the paddy chaff smoked cat fish was 48.72%; a little bit lower than coconut shell smoked cat fish that was 51.27%. TPC on paddy chaff treatment was 53.33 CFU/gr; higher than coconut shell treatment that was 46.67 CFU/gr. Organoleptic value of smoked cat fish treated by paddy chaff liquid smoke was 8.26 and coconut shell was 8.22. It was found that benzo(α)pyrene content in the paddy chaff liquid smoke was not detected and in the coconut shell liquid smoke was 11.351 ppm. Examination of t-test Independent sample to the TPC and moisture content showed P>0.05.

Abstract

Marine invertebrates that are mainly accumulating within coral reef ecosystems such as soft corals, sponges, tunicates, and bryozoans have long been recognized as the prolific sources of structurally unique and diverse natural products since they provide a large proportion of bioactive compounds with different biological activities.Unfortunately, the supply of these bioactive natural products is usually insufficient to meet the ultimate development of most marine natural products. The concentrations of many highly active compounds in reef’s invertebrates are often minute, accounting for less than 10-6% of the wet weight. This problem has been viewed as the most significant threat regarding the development of pharmaceutical from reef’s invertebrates. The secondary metabolites from bacterial symbionts, on the other hand,is a rapidly growing field, due to the suspicion that bioactive metabolites obtained from invertebrates may be produced by their bacterial symbionts. In particular, from sustainability point of view, isolating bioactive-producing bacteria is obviously offers a much better approach than cultivating and harvest invertebrates, which are in most cases extremely difficult.Bacteria isolated from living surfaces, in particular from reef’s invertebrates, are a promising source of natural products. It is expected that still quite a few parts of unexplored culturable bacterial symbionts exists in the reefs. Such information might be desirable, as these bacterial symbionts may serve beneficial purposes as the source of secondary metabolites including novel marine natural products.

Abstract

Research on the topographic changes due to Aceh earthquake, December 2004 and Nias earthquake, March 2005 was carried out at Weh, Simeulue and Nias islands from end of July until August 2005. The topographic changes were measured based on the present position of uplifted coral reefs with geodetic methods. Research results shows northwest part of Simeulue Island uplifted 1.55 up to 1.60 meters after earthquake on December 2004 and three months later southeast part of Simeulue Island and northwest part of Nias Island uplifted 1.70 up to 2.70 meters due to earthquake on March 2005. The raised shallow water reef flats become new land and apart of previously shallowest reef slope become new reef flats.

Abstract

The oceanographic research in Nangroe Aceh Darussalam waters post-tsunami was conducted on September 2006. Foraminifera which easily found as element of marine sediment was used as a tool to understand the trace effect of tsunami to marine sediment on the research area. Foraminifera is a single cell organism which has hard cover (test) as a primitive skeleton, that would remain in sediment for a long periods. Samples were carried out from west, north and east part of Nangroe Aceh Darussalam (NAD) Province waters using box-corer. The result showed there have been a mass of energy that force the sediment sliding and triggered the mixture of shallow and deep species of foraminifera in research area, particularly in western part of the waters.
