AbstractFisheries has a major contribution for the Indonesian economy both on a local and national scale. However, the phenomenon of climate change can threaten the sustainability of this sector. Therefore, a scientific approach is needed to determine the level of risk and adaptation strategies for fisheries, one of which is through vulnerability analysis. Vulnerability is the final analysis resulted from the analysis of sensitivity and exposure. Both of these analyses are important to determine the parameters that will affect the value of the fishery vulnerability to climate change. This research is focused on sensitivity and exposure analysis with the coverage limit is the province area to determine the sensitivity and exposure index that exists in the study area. The result will be important input in further research for the vulnerability of capture fisheries to climate change. Three provinces in Indonesia were selected through purposive sampling method. The source of data for indices variables were using recorded data in 2009-2020 from relevant sources. Result described that SST variability in the three provinces has the same pattern. In the exposure analysis, the SST is linked to the catch resulting in different exposure statuses in each province. It also illustrated those areas with a very high number of fishermen and catches will have very high sensitivity. The research will support in the sustainable management of capture fish at the province scale.

Abstract
Peptidoglycan recognition proteins (PGRPs) function as the pattern recognition receptor involved in antibacterial innate immunity. Evidence have showed that the molecular structure and function of PGRPs was conserved in vertebrate. However, as the pivotal species in the evolution of vertebrates, reptiles are believed to be the first vertebrates that have escaped from the aquatic environment and are able to adapt to a variety of different terrestrial lives, few studies about the PGRPs in reptiles has been reported. The Chinese soft-shelled turtle, Pelodiscus sinensis, is an ancient, secondary aquatic reptile with high economic value and nutritional value in Asia, which occupies a unique position in the animal kingdom and has important research value. In the latest research, a PGRP gene which was classified into the member of short-type PGRP family was characterized in Pelodiscus sinensis. This paper presented the latest findings on the molecular structure, expression pattern and function feature of PGRP-S from Pelodiscus sinensis, aiming at revealing that PGRP in vertebrates is evolutionarily conserved.
Numerical study of the circulation and water transport in Beibu Gulf: A short communication
Authors: Zhang J , Chen B , Zhu D 
Published: November 2021

Abstract
The Beibu Gulf, located in the northwestern South China Sea, is rich in oceanic energy and biological resources. Based on the FVCOM model, a three-dimensional numerical model was adopted in the study, which was validated with the observation data. The results show that Beibu Gulf is a typical diurnal tidal area. The K1 and O1 tide have an amphidromic point near Hue, Vietnam, forming a rotary tidal system. From the amphidromic point, the amplitudes increase gradually, eventually reaching more than 80 cm and 100 cm, respectively. The maximum amplitudes of M2 and S2 tide are about 70 cm and 10 cm, respectively. Meanwhile the tidal current presents a typical rectilinear flow in Beibu Gulf, with strong the diurnal tidal currents. Seasonal changes in the circulation structure of Beibu Gulf are obvious. The Beibu Gulf is generally controlled by a non-closed anticlockwise circulation in winter. In summer, there are two counterclockwise eddies. The tidal residual current flowing through Qiongzhou Strait goes west all year round, with the largest average flow flux of 0.07 Sv in winter. Based on DYE module from FVCOM, pollutants from the Pearl River Estuary pass through Qiongzhou Strait, and reach Weizhou Island after 109 days. This is of great significance to the monitoring and control of red tide, and the protection of marine ecological environment in Beibu Gulf.

Abstract
Yellowfin tuna Thunnus albacares is one of pelagic fish that has high potential and economic value in Banda Aceh. Utilization of this resource in Banda Aceh is using purse seine units, with the number of purse seines continuously increasing. Therefore, management needs to be done so that optimal productivity can be maintained. This study discusses the estimation of catch and effort at maximum sustainable yield (MSY) of yellowfin tuna based on catch per unit effort (CPUE) and purse seine production in Banda Aceh during 2013-2018. Mathematical analysis was carried out using the equilibrium approach with the Schaefer model. The highest catch of yellowfin tuna reached 191 tons (July) and the average CPUE for yellowfin tuna was 0.796 tons/trip with CMSY of 2,482 tons/year and EMSY of 2,765 trips/year. From 2015 to 2018, the trend of biomass continued to decline and overfishing occurred during this period.

Abstract
Proper flood control plays an important part in designing hydraulic structures and environmental safety measures. However, in Iraq, a clear understanding either of the estimation or management of the magnitude of flooding is yet to reach a higher level. This has resulted in grave and frequent damage to much property and life in Maysan town. Therefore, this study was focused on the Flood Hazard contro; in the River Tigris at the downstream of Al-Kut Barrage to the Al-Musandaq Escape, by adopting the HEC RAS model. Here, information related to the hydrological and topographical Digital Elevation Model (DEM) data were used as the input data. The hydrological data enabled the estimation of the flood depth of the river, for April 2019. All the geometric data were prepared by the HEC-RAS model. The unsteady-state model simulation was performed employing the input data. In this study, the best method for flood control and management is to design a weir having an optimal level, the optimum level that does not permit the passage of a flow that exceeds 700 m3/s to the city of Maysan during the flood season and a flow that is not below 250 m3/s during the dry season, is 9.406 m.

Abstract
This research focuses on measuring of specific activity of natural radioactive sources (238U, 232Th and 40K) in some types of secondary ceilings that used as a decorate material and available in Iraqi markets. The measurements were done using gamma ray spectroscopy system that based on NaI(Tl) Detector. Also, the radiological hazard indices have been assessed for all samples in present study. The results show that the specific activity vary from 8.7±0.6 to 32.9±2.3 Bq/kg for 238U, 2.9±0.2 to 40.3±1.5 Bq/kg for 232Th, and 117.4±2.6 to 649.1±7.9Bq/kg for 40K. The latter levels were compared with the world mean values that reported by the UNSCEAR 2008. It was found that all values of 238U and 232Th were below the world wide published values, while the values of only two samples of 40K were above the upper range of the world wide published values. Regarding the average values of radiological hazard risk were found to be within the permissible limit according to the OECD, UNSCEAR 2000, and ICRP. It can be concluded that natural radioactivity levels together with radiological hazard risk studied from the most of the secondary ceilings samples available in local markets of Iraq within natural rates of permissible limits and may not cause any danger to the human when being used.

Published: November 2021

Abstract
A modest quantity of fluoride can increase the mineralization of teeth and reduce their cavities. But the presomerence of fluoride in excess in water can lead to severe disease infertility. In the past few decades, scientists have thus been preoccupied with developing ways to reduce sewage fluoride concentrations and reduce their effects on human health. The present study is aimed at using the technology of electrocoagulation to remove fluoride from polluted water. Tests have been done to examine the elimination of fluoride with a rectangular electrocoagulation cell and examine the impact of the experimental aspects on fluoride extraction, specifically electrical current, electrode spacing, and pH. The authors found that 93% of the fluoride has been extracted using 5mm spaced electrodes with a current density of 2 mA/cm2 and a level of pH of 7 from the polluted water after 20 min of processing. Experimental factors considerably impact the efficacy of fluoride removal. In the acidic environment, greater effectiveness of fluoride removal is being attained. The elimination effectiveness depends directly on the electric current, whereas the distance between poles is adversely linked to fluoride elimination.

Published: November 2021

Abstract
This study is intended to analyze the management aspects of indigenous lands in environmental conservation. This research applies qualitative grounded research methods from the sociology-anthropology-ecology—research shop in Riau Province. The results of the study found that many indigenous peoples had lost their indigenous lands and local wisdom. Therefore, to maintain the sustainability of indigenous land conservation, it is necessary to carry out eco-culture management by considering the following points: First, the right to self-determination regarding the cultural identity one has. The second is territorial rights and indigenous land. The third is collective human rights. Fourth is cultural rights. Fifth is the right to adhere to their own religious and moral belief system and values. Sixth is the right not to be discriminated. Seventh is the right to participate fully in the political process. Eighth is the right to obtain compensation for any activities that have a detrimental impact on the environment and social, cultural, spiritual and moral values. This eco-cultural management perspective needs to be implemented in the government’s socio-political policies, people’s economic policies and ecological sustainability policies.
