This study was conducted from June to September 2016 and located in Kampar Sub-district, Kampar District, Riau Province. This study aims to analyze the implementation of corporate social responsibility program at PT. PSPI in public service environment and environment around the period 2013-2015, analyze the factors that influence the implementation of CSR program and analyze the most dominant factor in the implementation of CSR program in PT. PSPI period 2013-2015. The results of this study explain that PT. PSPI conducts its CSR program well, among others: sustainable development infrastructure, religious facilities, sports facilities, health facilities, community economy and education for the community around the company. So that public relations as well as the Company continues to run well and give confidence to the public that the company has a concern in the field of CSR. Based on the results of research on the implementation of public services that the Company is more focused on Economic and Social aspects when developing CSR programs because the community has an influence on the existence of the company. Each of the company's operational activities will have the potential to positively and negatively impact the communities surrounding the company. If companies pay attention to social aspects then the company will be able to achieve development and sustainable development. Companies in conducting business activities are not only oriented to profit only. Although achieving maximum profit is the main purpose of the establishment of a company, but the company can not achieve these benefits at the expense of the interests of other stakeholders ie stakeholders. Every company has responsibility for its actions and business activities that have an impact, either directly or indirectly on the stakeholders and the environment in which the company is located.

Epibenthic dinoflagellates are of important as primary producer in coastal and oceanecosystems. But it has potent toxins causing harmfull effect to marine fauna as well as to human.The present study aimed at analyzing the abundance of three genus ; Ostreopsis, Prorocentrumand Gambierdiscus in Teluk Bayur Bay, West Sumatera, which sampling were conducted inNovember 2014. Environmental parameters were including Nitrate, Phosphate concentration anddensity of Sargassum vegetations were measured which preasumably influence the dinoflagellatesabundance. Apparently, abundance of dinoflagellates ranged from 2061-7116 cells/g. Samplingstations had no effect on abundance of dinoflagellates. Water quality (N, P and Sargassumvegetation density) had no effect to the present and abundance of dinoflagellates, in all samplingstations.

Analisis Kandungan Logam berat Cu, Pb dan Zn pada Air, Sedimen dan Bivalvia di perairan Pantai Utara Pulau Bengkalis Bambang Irawan; Bintal Amin; Thamrin Thamrin

Analysis of heavy metals Cu, Pb and Zn in water, sediment and bivalves in the Northerncoast of Bengkalis Island Riau Province was conducted in September 2013. Samples were takenfrom 4 stations and environmental parameters such as temperature, pH, salility and current speedwere also measured. The results showed that all the water quality parameters measured in thepresent study were still in the range of tolerable level for aquatic organisms.The mean heavymetals Cu, Pb and Zn concentrations were 0.827; 0.406; 02.104 mg / L in seawater and 42.165;1.892; 78,556 μg/ g in sediment. Meanwhile the concentrations of those metals in bivalve were70.598; 3.762; 186.702 μg/g in Polymesoda expansa and 74.378; 3.903; 129.619 μg/g in Pharellaacutidens. Positive correlations between concentrations of Cu, Pb and Zn in water and sedimentwith concentrations in both bivalves species were found. Based on the PTWI calculation it issuggested that both species of bivalves were still safe to be consumed. Concentrations of heavymetals in sediment in the northern coast of Bengkalis Island were still below the ERL and ERMstandard indicating no serious pressure yet on the living organisms in the surrounding areas.

One of the environmental problems caused by the increasing growth of the industry.Industrial waste generated that goes into the soil can alter soil properties. This studyreviewing the nature of the soil as a result of the distribution of residual waste CPO (CrudePalm Oil) industry mills. This study uses the characteristics of resistivity and soil nutrientproperties. Soil resistivity properties were tested by making a model before and after thedistribution of waste residue does CPO. Then validated against field measurements, fieldmeasurements comparing the data with the model. To see the changes in nutrient content ofsoil Laboratory Testing properties of soil nutrient changes. The results showed that theresistivity properties change and nutrient content of the soil before and after the distributionof waste residue subjected CPO. Soil resistivity values that have mixed by CPO residualwaste is higher than the value of soil resistivity is not mixed waste palm oil residues, while thecontent of soil nutrients among other properties, increasing soil pH, Include content C-Organic (%) / Inceneration, P-Available (ppm) / Bray-1, N-Total (%) / Kjedahl decreaseddramatically.
