Abstract

Laboratory study on the concentration factors and steady state condition of Cadmium (Cd) by green mussel (Perna viridis) has been carried out. Radiotracer 109Cd was applied in the study. The objective of the study was to evaluate bioaccumulation parameters including con- cent ration factors and steady state condition of cadmium by green mussel from dissolved phase. It was found that both salinity and temperature had significant effect (P<0.001) on accumulation rate of 109Cd. The highest concentration factor of Cd (31,23-54,09) was appeared in water salinity of 29% and of water temperature 31°C. Apparently, green mussel accumulated 72,21-107,80 Bq/gr Cd at the steady state condilion. It revealed that the small Perna viridis (5.2 cm in length) accumulated 109Cd about 107,80 Bq/gr, whereas the bigger size of the green mussel (6.6 cm in length) had an uptake of about 72,21 Bq/gr.

Abstract

Dumai is area endemic of Dengue disease (DBD) with condition of environmental sanitary ingeneral has not well. Purpose of this research is to know image of condition of environmentalsanitary in Kota Dumai and sees are there the relation of condition of household area sanitarywith existence larvae of vector dengue and area sanitary aspect what which most dominantrelated to existence larvae of vector dengue in disease gristle area of Kota Dumai. This researchis research type of observasional with planning "Cross Sectional". Research subject ishousehold 102 households who live in gristle DBD. Sampling is done in" random sampling"Research independent variable is condition of household area sanitary covering aspect: supplyof cleanness water, management of garbage and practice of eradication of mosquito dengue.Research dependent variable is existence larvae of vector dengue. Result of analysis univariatshows condition of household area sanitary in general is unfavourable (62,7%). Out of 555containers contains water which are positive larvae at is 186 containers (33,51%). Result ofanalysis Rank Spearman shows there is relationship signifikan between condition of householdarea sanitary with existence larvae at (Rho = Rho=0,586 and p=0,000). While result ofregression analysis shows area sanitary aspect that is most dominant related to existence tolarvae at is practice of household in PSN-DBD with P value 0,000 and correlation value =0,635. Equally, factor that is very significant of existence larvae at vector dengue is PSN-DBD.

Abstract

IUCN (International Union for Conservation of Nature) categorizes the Sumatran tiger as an endangered species in crisis, which is the highest category of extinction threat. One of the causes of the extinction of the Sumatran tiger is conflict with humans. The meeting of human activities and the roaming area of tigers in the same space creates an adverse conflict on both sides.This research was conducted in the Hutan Tanaman Industri of PT. Arara Abadi, Tapung District, located in Siak Regency and Kampar Regency, Riau Province, to be precise in Rantau Bertuah Village and Garo City Village. The research method is a qualitative approach. Primary data obtained from observations and interviews, and document studies. Secondary data obtained from literature studies are landscape maps, animal monitoring data, and biodiversity reports of PT. Arara Abadi, Tapung district. In addition, the literature study is also sourced from the Riau BKSDA wildlife monitoring data document. Result: Conflict between humans and Sumatran tigers occurred in the concession area of PT. Riau Abadi Lestari to be precise in a conservation area, in a community plantation area. The social losses that occur are in the form of psychological losses, while other losses such as human injuries or death do not occur. The economic loss was Rp. 42,000,000. In addition, some residents lost their working days to cultivate their gardens. The frequency of conflicts that occurred in Rantau Bertuah Village did not recur and conflicts that occurred in Kota Garo Village occurred repeatedly throughout 2020.Conflicts that occur in Rantau Bertuah Village are low risk. Meanwhile, the conflict that occurred in the village of Kota Garo was included in moderate risk.
