"Three specimens of Plectranthias retrofasciatus Fourmanoir and Randall, 1979 and one specimen of P. randalli
Fourmanoir and Rivaton, 1980 were collected by first author from fish market, Bitung, North Sulawesi on June
and September 2010. The specimens were deposited at LBRC-F, the reference collection of LIPI Bitung, Technical
Implementation Unit for Marine Biota Conservation, Research Centre for Oceanography, Indonesian Institute of
Sciences, Bitung, Indonesia. Plectranthias retrofasciatus is closely related to P. megalophthalmus and P. knappi,
in sharing some morphological characters as snout length and interorbital width, while P. randalli differs to other
species by having a moderate deep body proportion. Initially these species known only from New Caledonia for P.
retrofasciatus and Chesterfield Islands and southern Taiwan for P. randalli respectively. The two species of anthiine
fishes collected from Bitung, Indonesia bringing the total number of species of this genus known in Indonesia to six.

"ABSTRACT
Providing accurate information on suitable multispectral satellite sensors for mapping coral reefs in Indonesia is a challenge for coastal remote-sensing experts. As coral reefs vary in spatial extent, shape, length, perimeter and/
or distance to shore, the mapping of coral reefs will need different satellite sensors depending on the objectives and the kind of information required. This work compares the suitability of two kinds of multispectral satellite sensors for mapping coral reefs in Indonesia, high and moderate spatial resolution. This was done through a case study of Wakatobi Marine National Park since that represents many types of coral reef in Indonesia (fringing, barrier, atoll, and patch). Indonesian coral reef shapefile data 2010 was downloaded from UNEP (United Nations Environment Programme) website, and Landsat 7 ETM + images, path/row 112/064 was used to determine the terrestrial area of Wakatobi Islands. Both high and moderate spatial resolution sensors are suitable for mapping the benthic communities and geomorphic zones on coral reefs. The former are more accurate but they are also much less cost-effective, especially over large areas.

"A small collection of majoid spider crabs of the genus Paratymolus Miers, 1879, s.l from Lombok Island, Indonesia contains four species namely P.hastatus Alcock (1895), P.coccus Loh & Ng (1999), P.cygnus Loh & Ng (1999), and Litosus sexspinosus (Miers,1884). Except for L. spinosus, the three other species are new records for indonesia. Paratymolus coccus is previously known from only female specimens, and the presence of male specimens in the collection studied provides the oppurtunity to complete the description of male characters. Paratymolus hastatus is reported for the first time outside Indian Ocean and P.cygnus is recorded for the first time after its description."

"ABSTRACT
Several harbours in North Jakarta have been polluted by spills of oil and their derivates. We suggest that diverse
species of crude oil and polycyclic aromatic hydrocarbon-degrading bacteria inhabit these harbours. An experiment
was undertaken in 2007 to isolate crude oil and polycyclic aromatic hydrocarbon (PAH)-degrading bacteria from
oil-polluted harbours, such as Muara Baru, Sunda Kelapa and Tanjung Priok. Sea water and sediment samples
were collected twice, in March and April. Crude oil and PAH-degrading bacteria were isolated from enrichment
culture of samples in an enrichment medium (SWP), using ONR7a medium with the addition of 5 types of PAH
gases or Arabian Light Crude Oil 210 (ALCO 210) onto medium. This study reported that fluoranthene and crude
oil-degrading bacteria were the major bacteria isolated from the three polluted harbours. In total, 109 isolates have
been collected which can degrade crude oil (29% of total isolates), fluoranthene (33%), fluorene (20%), pyrene (7%),
dibenzothiopene (6%), and phenantrene (5 %). Cultivable bacteria have been isolated mostly from the Sunda Kelapa
samples, with fewer in those from Muara Baru and Tanjung Priok, respectively. Among these isolates, 5 isolates
have the capability to degrade 5 types of PAH and ALCO 210. They were Alcanivorax sp. B-1084, Pseudomonas
sp. D5-38b, Alcanivorax sp. TE-9, Bacillus sp. L41, Alcanivorax dieselolei strain B-5 clone 1. "

"ABSTRACT
Bangka Island is well known as the world's largest tin producer. The inland and offshore tin mining has profound effects on the coastal environment, resulting in the high sedimentation in the water. Many corals suffered physiological damage due to low light intensity. The distribution of stony corals and the status of coral reefs was surveyed at 6 sites in West Bangka waters in October 2012. A total of 72 species of corals belonging to 33 genera and 12 families were found, and 4 species were distributed at all research sites. The live coral coverage was 36% on average and was categorized as being in fair condition. The coverage was 0% at Kamboja Island where the corals were the most affected by tin mining. The sediment flowed out from tin mining, blocked the light, and settled on the coral's surface. Consequently, many corals were buried and the live corals decreased. It is obviously necessary to reduce and control the tin mining.

"The volatile chemicals from species of wild Cinnamomum spp. (C. racemosum, C. cuspidatum, C. politum, C. javanicum), Etlingera spp. (E. pyramidosphaera, E. megalocheilos, E. coccinea, E. elatior) and Schizostachyum spp. (S. blumei, S. brachycladum, S. lima, S. pilosum) found in Sabah were investigated. The oils were obtained from the bark, rhizome and culm of respective specimens by hydrodistillation and the profile of volatile chemicals was obtained using Gas Chromatography- Mass Spectrometry (GCMS). Dominance of eucalyptol, terpinen-4-ol and eugenol were consistent among the species from genus Cinnamomum. aromadendrane oxide, lauryl aldehyde, elemicin, borneol and 1-dodecanol were predominant among the species from genus Etlingera. α-elemol, coumaran, guiacol-4-vinyl, palmitic acid and phytol acetate predominate the species from genus Schizostachyum. Strong inhibition against Staphylococcus aureus (MIC: 5.62 ± 0.5 μg mL-1) were exhibited by essential oils of C. cuspidatum and E. coccinea, oil of S. blumei inhibited Listeria monocytogenes (MIC: 4.60 ± 0.5 μg mL-1), oil of C. javanicum inhibited Salmonella typhimurium (MIC: 5.50 ± 0.5 μg mL-1). meanwhile the oil of C. politum suppressed Salmonella enteritidis (MIC: 5.20 ± 0.5 μg mL-1) was measured using microdilution method. these findings reveal the potential of selected plants used by indigenous communities of Borneo as antimicrobials in food, cosmetics and pharmaceutical industries."

The diversity of wild banana species in Sulawesi was investigated based on the morphological characteristics of herbarium specimens collected in Sulawesi and deposited in the Herbarium Bogoriense, Bogor, Indonesia (BO). New specimens were collected from Central, North, South, and Southeast Sulawesi, and digital type specimens were also used in this study. The aim of this study was to describe the diversity of wild banana species in Sulawesi as most Musaceae specimens stored at BO have not been identified. By examinating 110 sheets of herbarium specimens, five species of Musa, including two infraspecific taxa of M. acuminata housed in Sulawesi, were identified. Musa acuminata, M. celebica, and M. textilis were previously reported from Sulawesi. However, M. balbisiana and M. itinerans are two new records of wild banana species in Sulawesi. Identification keys, descriptions, distribution maps, and line-drawing illustrations of these two species are provided."

"ABSTRACT
Indonesia is particularly rich in Echinoderms and North Sulawesi lies at the geographic centre of this biodiverse marine realm. While further studies on Sulawesi Echinodermata are required in order to obtain full understanding of current biodiversity status, preliminary SCUBA and intertidal surveys in early 2012 in the vicinity of the Lembeh Island, a region little explored previously, recorded a total of 76 species of 4 classes (Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea) from shallow waters (0-40 m) at 36 sites (sea grass, coral rubble and reef). The class Crinoidea is not reported here. A review of Echinoderm literature for North Sulawesi noted that there are 114 species belonging to 5 classes of Echinodermata.

"ABSTRAK
Reduction of free fatty acid (FFA) in used palm oil was determined after treatment of waste cooking oil with an adsorbent derived from coffee bean husk ash. Coffee husks were burned at 600 ºC for 12 hrs to obtain the adsorbent ash. Free fatty acid removal efficiency was optimized with respect to ash dosage, contact time and temperature. It was found that shaking ash (1 g) with waste palm oil (50 g) at 250 rpm and 30°C for 330 min gave the highest reduction in free fatty acids (FFA) (1966 mg/g). The adsorption isotherm was followed by Temkin (R2 = 0.9283) and Freundlich models (R2 = 0.9146). The adsorption of FFA at all adsorbent doses followed pseudo-second order kinetics (R2 = 0.9817-0.9999). A thermodynamic study revealed that the changes in enthalpy, entropy and Gibbs free energy were 89.07 kJ/mol, -0.25 kJ/mol.K and -5.15 to -12.17 kJ/mol, respectively. The coffee husk ash (5 g ash / 50 g waste palm oil) was found to reduce FFA by 100% at 30°C.
