Abstract
The aim of this study was to evaluate the effects of different levels dietary supplementation of Terminalia catappa leaves (TCL) viz: 250; 500; and 1000 g kg−1 on the growth, blood profile, and survival of Pangasianodon hypophthalmus. Four groups including control of four replications of forty fish (Initial weight 0.230±0.004 g; initial length 31.43±0.18 mm) per tank were fed the test diets for 12 weeks. Results showed that dietary 1000 g kg−1 of TCL negatively affected all growth parameters, WBC, Hb and Plt. Feed conversion ratio (FCR) was found significantly higher than other groups, while RBC and Htc were not affected by any concentration of TCL supplementation. Further, fish fed 250 g kg−1 TCL in the diet showed significantly higher survival. This finding concluded that TLC which contains tannin, flavonoid, and some important phytochemicals reduced the growth of fish but significantly increased survival and FCR.

Abstract
Turmeric is commonly used as stimulant and it is an important ingredient in tradisional herbal medication. A study aims to understand the blood condition of Pangasius hypophthalmus fed on turmeric enriched pellets and were infected with Aeromonas hydrophila has been conducted from August to October 2018. There were 3 treatments applied; namely P1: Fishes were fed with turmeric enriched pellets of 0.5 g/Kg feed, P2 (0.7 g/Kg feed) and P3 (0.9 g/Kg feed). The negative control (Pn) were the fish that was not receive any treatment, while the positive control (Pp) was the fish that was infected with A. hydrophila, and was not given turmeric powder. Fourteen days after being fed on turmeric enriched pellets, the fishes were infected with Aeromonas hydrophila (0.1 ml of 108 of A. hydrophila culture). Totally 15 fishes from each treatments were studied. Blood were taken from vena caudalis using 1 ml syringe wet with 10% EDTA and then were checked using binocular microscope for erythrocyte and leucocyte number. Haematocrite and leukocrite levels and types of leucocyte were also studied. Results shown that the blood condition of turmeric treated fishes were different. The total erythrocyte of the negative control (Pn) fishes was 2.136.670 cells/mm3, the positive control (Pp) was 1.423.300 cells/mm3 and that of the treated fishes ranged from 1.520.000 to 2.886.700 cells/mm3. While the number of the leucocytes of the negative control fishes was 153.200 cells/mm3, the postive control (Pp) showing infectious condition with 726.000 leucocyte cells/mm3. The leucocyte number of the turmeric treated fishes (P1, P2 and P3) showing normal values, ranged from 107.000 to 2.069.000 cells/mm3. Based on data obtained, it can be concluded that the turmeric enriched pellets improved the ability of the fish to cope the problems caused by A. hydrophila infection

Abstract
The coast of Aceh along the northern tip of Sumatra had an important role since the beginning of the first millennium AD. The area was used as a transit point for the maritime silk road of the gate of the Malacca Strait. Many old settlements and ancient fortresses were found on the area. One of them is Indrapatra fortress. At present, the Indrapatra fortress has been slowly damaged by weathering and was also hit by disasters. Parts of the main building is still intact, while the other parts have been damaged and buried by sand deposits. In order to preserve the building, some actions need to be taken such as re-mapping the existence buildings and the buried parts as well. For this reason, a geomagnetic survey has been conducted to delineate the remains of the building at the subsurface. Data of total magnetic field intensity were acquired in an area of 31,255 m2 with a grid of 3 meters for each station so that the measurement covered the whole area of the target site. Total magnetic field anomalies were calculated using diurnal and International Geomagnetic Reference Field corrections. The obtained anomalies represent magnetic objects (archaeological structures) which buried beneath the surface. To obtain a more detailed form of anomalies several transformations, such as analytic signals, tilt derivatives, and horizontal derivatives were applied. The results of the transformations show several circular and elongated anomalies. The circular forms of anomalies are considered as buried wells, and the elongated forms are considered as channels which presumed connected the buildings in the area. The data showed that there are also foundations of the buildings made of stone structures cemented with lime plats.

Published: November 2019

Abstract
Plastic waste has been known as threatening pollution, especially to the aquatic environment. Larger-sized plastic particles have noticeable impacts on the marine ecosystem. Current studies have revealed serious menaces of small plastic particles namely Microplastics (MPs). In contrast to the larger particles, little is known about the interaction between MPs and the surrounding microorganisms. MPs pose more threats to the environment and human health due to their abilities to influence the microbial ecology of the marine environment. This paper will discuss the MPs effect on the aquatic environment from the microbiological points of view consisting of the biofilm formation on MPs, the exchange of microbial genes on MPs particles and also the role of MPs as the reservoir for antimicrobial and metal resistance genes.
The phylogeography and taxonomy of a model-species complex, the blue-spotted maskray (formerly Neotrygon kuhlii): a short review
Authors: Borsa P , Arlyza I S , Barber P H 
Published: November 2019

Abstract
The present paper reviews the phylogeography of an emblematic Indo-West Pacific stingray and aims at linking its taxonomic implications with conservation management. The blue spotted maskray was once understoodto be a single species widely distributed in the Indo-West Pacific, from the Red Sea to Fiji and from southern Japan to New South Wales. Genetics have shown that it actually consists of a number of distinct lineages with parapatric distribution. Phylogenetic data suggest an evolutionary origin of this species complex in the southwestern Pacific in the Miocene. The blue-spotted maskray progressively colonized the Indo-West Pacific from the East to the West. The lineages in the western Coral Triangle and the Indian Ocean are the most recent. Against this updated taxonomic and phylogeographic background, there remains a need for research on the population dynamics and fisheries management of this increasingly threatened species complex.This paper is dedicated to the memory of Dr Irma S. Arlyza.

Published: November 2019

Abstract
The Makassar Strait (MS) connects the Pacific Ocean and Indonesia Waters via the Indonesia throughflow system. The flow varies because MS is also influenced by the monsoon. To determine the monsoon effect, we applied the two-dimensional numerical model with 6 hourly wind data. It was used to predict the MS current circulation during February, April, August, and October. According to recent studies, the results showed a good verification. The currents in the MS were dominated from the north of MS. The currents moved to the south of MS but sometimes deflected to the north. The currents were stronger during August and weaker during February. In August, the current from the north of MS moved to the south of MS, and it was partly deflected toward the north around Sulawesi Island. There was also the current from the south of MS directed toward the north. While in February, the current around Kalimantan Island was always to the south of MS. Based on the results, the MS currents were dominated by the currents from the north of MS or the Pacific Ocean.

Abstract
The thermocline is a sea layer with a change in temperature to depth quite quickly. We had to study this layer because it had an important contribution to thermohaline flows, upwelling, and fish migration. This paper aimed to map the vertical profiles of temperatures and thermocline gradients in the Andaman waters during the transitional season, October 2017. Analysis of the thermocline layer was based on vertical temperature data from the CMEMS model which were verified with SST from Aqua MODIS 4 km. The thermocline layer was indicated by ΔT / Δz ≥ 0.1 °C and started from the depth of 40 m. CMEMS SST verification on October 2017 showed good results (MAPE = 0.0188, r = 0.68). The thermocline layer was found thicker off the west coast of Sumatra, the Indian Ocean (Station 1) than in the Andaman Sea. Generally, the thermocline layer was at a depth of 66 -131 meters on October 2017. The thermocline gradients were 0.12 - 0.23. These results indicated that in the transitional season, the thermocline location in the Andaman Sea was shallower or less than 200 m.

Abstract
In Aceh, oyster hunting is mostly carried out by women, by sitting or squatting inside the estuary water. The job is carried out every day for many years, with an average duration of two until three hours/day. During this activity, the female genital organ is an open cavity which is an entry point of substances into the body. The residential drainage channels in Banda Aceh City, consists of Alue Naga and Krueng Tibang Rivers Furthermore, the water quality of the Krueng Cut river is in class III, and it contains coliform bacteria, fecal coliform, and streptococcus fecal bacteria. However, the oysters extracted contain lead, cadmium, and zinc, which are above the safety level. The purpose of this study was to determine the effect of age, and duration of work using vaginal douches on pap smear result test in woman oyster seekers. The research subjects comprised of 60 respondents, which was obtained by purposive random sampling. The result showed that 75% of the respondents in abnormal category (PAP II), had pap smear results. A total of 39 respondents (65%) were in the reproductive age, with 35 (58.3%) of them having worked for more than five years, while 25 (41.7%) did not utilize the vaginal douching after work. Furthermore, it influences the age of Pap smear results (p-value=0.00), the length of work affecting the pap smear result test (p-value=0.00), and the vaginal douching that influences the pap smear results (p-value=0.001). Logistic regression analysis showed that the most influential variable on Pap smear results was the length of work (p-value=0.005) and vaginal douching utilized (p-value=0.002), with its results not affecting by age.
