DIRECT BACTERIA COUNTING IN THE BANDA SEA Ruyitno, -
Marine Research in Indonesia Vol 27 (1989)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Bacteria counting in the Banda sea were carried out in two seasons during Snellius II Expedition.Â In August 1984, representing the southeast monsoon where upwelling is expected, bacteria counts were higher than in February 1985, representing the northwest monsoon where downwelling is expected. Some biological parameters of the Banda Sea were in support of the bacteria numbers in the expected upwelling region.

Indonesia is situated in the Coral Triangle region that has the worldâs highest coral reef biodiversity. Therefore, coral reef monitoring needs to be conducted regularly to assess the condition of coral reef ecosystem for management purpose. There are several coral reef monitoring methods available such as the line intercept transect (LIT), point intercept transect (PIT), photo transect, belt transect and benthic towed-diver. In Indonesia, LIT and PIT are the most commonly used methods for coral monitoring. However, there is a main disadvantage when collecting data using these methods, that is scientific divers need to spend hours to input the data after dives. Here, we introduce an electronic logging instrument called Coral Input Data Instrument that helps to decrease the input data time by employing a look-up table system that simplifies data input process by replacing text with numerical coding. In addition, water quality data such as temperature, depth and visibility also are embedded in the electronic logging instrument. The instrument hardware consists of Arduino Mega 2560, keypad 4x3, LCD Module 16x2 character, real time clock, temperature sensor, pressure sensor, visibility sensor and micro SD card module. Arduino IDE 1.6.5 software is used to program the microcontroller. In this paper, we describe the design and implementation of the instrument in the field.

Twelve species of Crustacea of the family Palicidae were collected from Indonesian waters. Together with two species from the Philippines and type specimens of Crossotonotus compressipes A. Milne Edwards, 18 73, are studied and Manella spinipes is used for comparison. Two new subfamilies, four new genera, and six new species are described and the type of Crossotonotus compressipes has been designated.

THE EFFECTS OF SOME PESTICIDES ON REEF CORALS Lamberts, Austin E.
Marine Research in Indonesia Vol 17 (1977)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

While investigating a reef coral kill in Samoa it was speculated that this might have been due to contaminationÂ by some chemical. Subsequently, scleractinian reef corals were tested to assess their reactions to 12 commonly used pesticides and toxic substances. The chlorinated-hydrocarbons such as DDT and Endrin produced stress effects in corals subjected to 2ppm for 24 hours in in-vitro studies although the corals continued to deposit skeletal calcium. In-vivo tank experiments suggested that small amounts of these substances in seawater stimulated the corals to deposit skeletal calcium. Other pesticides were much less toxic to the corals.

Today, many people know that the mythical mermaids of legendal stories originated from the animals belonged to the order Sirenia. Sirenians can be devided into two groups, manatees of the Atlantic coasts and the dugong of the IndoPacific area. Table I shows the present living species belong to the order Sirenia.

HABITAT HEALTH OF ILOILO RIVER - INSIGHTS FROM A STUDY ON BENTHIC COMMUNITY STRUCTURE Palla, Rocille Quilantang; Campos, Wilfredo Lopez; Campos, Annabelle del Norte-

Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

In west central Philippines, the monitoring of aquatic systems traditionally focused on dissolved oxygen values and biological oxygen demand, e.g. monitoring by the Environmental Monitoring Bureau around Panay Island. However, single or two factors are considered to be insufficient to assess habitat health precisely. In this paper, we investigated a benthic community and xamined their implications to habitat health of the Iloilo River. According to a prior benthic survey, warning signs pertaining to biotic, abiotic and community factors have been detected. The disturbed onditions in Iloilo River can be attributed to 3 factors; 1) its inherent topography, where bends serve as sinks for materials; 2) the lack of vigorous water exchange that promotes deposition and hinders complete flushing; and 3) the manner of utilization of the river by the local people. We thus concluded that: 1) monitoring for water parameters only is not enough to get a clear picture of habitat health; and 2) proposed that biotic components should be included for monitoring aquatic system.

REVISION OF THE INDO-PACIFIC SPHENOCARCINUS WITH A SINGLE ROSTRUM AND DESCRIPTION OF TWO NEW SPECIES (CRUSTACEA, DECAPODA, BRACHYURA, MAJIDAE) Guinot, D.; De Forges, B. Richer
Marine Research in Indonesia Vol 24 (1984)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Two species of the genus Sphenocarcinus A. Milne Edwards 1876, with a single rostrum exist in the Indo-Pacific and they are principally only known by their original description: S. cuneus (Wood-Mason 1891) and S. aurorae Alcock 1899. Each species is herewith redescribed, based on the examination of the types. Two new species are established. S. difficilis sp. nov., represented by numerous specimens from Madagascar (ORSTOM collection), proved to be an intermediate species between S. cuneus and S. aurorae. S. pinocchio sp. nov., (collected in the Makassar Strait, Indonesia (mission Corindon II), is characterized by its very Jong and strongly curved rostrum. One male specimen, also collected in the Makassar Strait, probably modified by a sacculinid parasite, and with a more curved, snub rostrum, can be regarded as an unusual form of S. pinocchio sp. nov. A key of the four Indo-Pacific Sphenocarcinus with a single rostrum is presented.

REPRODUCTIVE PATTERNS OF HOLOTHURIA SCABRA (ECHINODERMATA: HOLOTHUROIDEA) IN INDONESIAN WATERS Purwati, P.
Marine Research in Indonesia Vol 30 (2006)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

During 1993 to 1996, reproductive aspects of Holothuria scabra, one of the commercially important holothurian species in Indonesian waters were studied, which involved populations of Ambon Bay (eastern Indonesian waters), Saugi Island (central Indonesian waters) and Lampung Bay (western Indonesian waters). Those studies were reviewed in this paper, not only to reveal general patterns of reproductive seasons of populations throughout Indonesian waters, but also to provide more knowledge on gonadaltubule-development that has been rarely investigated on Indonesian holothurians. The review showed that the development of gonadal tubules amongst populations of Indonesian H. scabra were similar. Those included that: tubules across a gonad grew for one single reproductive cycle, and each tubule had equal opportunity to release their gametes in the same spawning event. These features conformed to general characteristics of this species throughout the world, and were different from the proposed tubule recruitment model of Smiley (1988). Each observed population showed fluctuation on gonad index, and individuals with fecund and/or post spawning gonads were recorded in most sampling occasions, resulting in fluctuation of gonad index. This attribute gave clue to through-year spawning activity with more intense during one or two periods in a year.

The full understanding of the distributio of the surface temperature and salinity requires the knowledge of the heat and water balance at the surface of the ocean as well as of the circulation. For southeast Asian waters the monthly averages of the climatological factors determining the heat and water balance are calculated and presented in the following for 15 regions.

POSSIBLE OCCURRENCE OF TOXIC AND HARMFUL PHYTOPLANKTON IN LOMBOK BAY, LOMBOK, INDONESIA Sidharta, Boy Rahardjo; Ahyadi, Hilman

Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Harmful Algal Bloom (HAB) incidences in Indonesian waters were increasingly occurred from time to time. Extensive and continous studies in this field are needed to be done in more areas in the country. This objective of this present survey were to determine the occurrence of potential toxic and harmful marine microalgae in Lombok, to reveal the diversity of marine microalgae found in the area, and to give some information on the occurrence of HAB phytoplankton in Lombok island. Plankton samples were taken from six stations in Lembar bay, Lombok on February, 2007. This survey found 23 marine microalgae species and two of those were potentially harmful and toxic, namely Dinophysis caudata and Gymnodinium catenatum. Four species, such as Ceratium spp, Dinophysis miles, Prorocentrum gracile, and P micans, were noted to be harmful though so far no report on adverse effect caused by these microalgae in the area. Diatom Chaetoceros spp were the most abundant phytoplankton in almost all of the sampling areas and followed by Ceratium furca and Protoperidinium sp.
