Abstract

Formal environmental education can be obtained at the school, because the school which isinvestment values about the environment in order to enhance students´ awareness of theenvironment. This needs to be inculcated in the students because they are the youngergeneration as a determinant of the future of the nation. Formulation of the problem in thisstudy is (1) whether there is a relationship between parental employment and livingenvironment with concern for the living environment (2) Which factor is most associatedwith concern of Students Cendana Junior High School Pekanbaru to school environmentbased on parental employment and living environment.Concern for the environment isinfluenced by various aspects such as knowledge, attitudes and responsibilities. Researchwas conducted in Pekanbaru Cendana Junior high school through survey methods, arequired primary data were obtained from leaners by questionnaire and secondary datahave been available at the school. Data analysis used chi-square tests and multipleregression analysis with helping of SPSS program.The results confirm that the studentscaring view of working parents whether they are CPI and non-CPI. Their parents who arenot CPI employees care more than CPI employees . While the students caring view ofliving environment in the complex and the outside of the CPI complex, the students who liveoutside of the CPI complex are more concerned than they live in the CPI complex. Comparethe children of CPI employees who live in complex and outside the complex, the children ofCPI employees who live outside the complex more concerned than they live in the complex.Then from the three variables that concern affecting are knowledge, attitude andresponsibility, the more dominant influence learners concern is the aspect of knowledge.

Abstract

The amount of solid waste at station 1 to station more than 2 type of solid waste in the Black Water Strait of each station is almost the same, where the Black Water Strait is dominated by the type of waste plastic and small pieces of wood. In Black Water Strait encountered type of waste that generally consist of plastics, paper, rubber, foam, jute sacks, leaves, and small pieces of wood. From this we can conclude that the solid waste at both stations originate from the same source ie domestic waste. The strong tidal currents provide a direct influence on the amount of solid waste that are found in every point of the study and vice versa if the lower the pressure, the current is the entry-level waste into gear tends to be decreased.Keywords : Comparative Study, Solid Waste, Selat Air Hitam, Meranti Island

Abstract

ABSTRACTA Study on the abundance of Chaetodontidae, coral cover and  relationship of  abudance with coral cover were conducted from May -          July 2019 in the Lagoi Waters of Bintan Regency of  Riau Islands Province. Abudance of fish observed with Underwater Visual Census (UVC) method while coral cover with Reef Check  method. Apparently the abundance of Chaetodontidae fish ranged from 313.3 - 603.3 ind/ha whereas coral cover ranging from 46 - 74%.Forthat, abudance of coral fish corelated (r = 0.977) with coral cover, suggest that, there is a very strong relationship between live coral cover and Chaetodontidae fish. Key words :Chaetodontidae, Coral Reef, Lagoi Waters

Abstract

This research was conducted in March 2015 to find out the structure of  diatom community and the distribution of abundance planktonic diatom in coastal around Dumai City. The survey method was applied in four stations with different characteristics, each stasiun consisted three sampling strata. The total of diatomwere 10 genera namely:Eucampia, Leptocylindrus, Guinardia, Rhizosolenia, Melosira, Coscinodiscus, Thalassiothrix, Rhabdonema, Nizschia, and Bacillaria. The most genera that commonly found was Rhizosoleniabecause yhis genera was being able to compete better than other genera. Base on the formulation of diversity index (H'), dominance index (D), and equability index (E), explained that the structure of diatomplanktonic community in all stations were in a state of balance. It  means there was not competition both places and food. The result of ANOVA test gained that the distribution of the diatom abundance was not significantly different among stations.   Key Words: abundance, diatom planktonic, Dumai

Abstract

This research was conducted in April to Mei 2019 to determine the content of organic matter and abundance of phytoplankton, to find out differences in organic matter and phytoplankton abundance between station and to know the relationship between organic matter content and phytoplankton abundance as reference for determining the condition of the Sungai Guntung estuary, Kateman Sub-district, Indragiri Hilir Regency, Riau Province. The method used in this study is  survey method, where the sampling locations consists of 4 research stations and each station consists of 3 sampling points. The results showed that organic matter content at station 1 had an average of 11.60 mg/l, station2 8.64 mg/l. Station 3 8.22 mg/l and station 4 8.22 mg/l. Phytopkankton species that found at Sungai Guntung estuary water is 21 species the Isthmia sp, Biddulphia sp, Chaetoceros sp, Rhizosolenia sp, Skeletonema sp, Thalassionema sp, Pleurosigma sp, Nitzschia sp, Synedra sp, Grammatophora sp, Thallassiothrix sp, Fragilaria sp, Navicula sp, Melosira sp, Asterionella sp, Cocconeis sp, Coscinodiscus sp, Stephanopyxis sp, Cyclotella sp, Bacteriastrum sp dan Oscillatoria sp. The highest abundance is in areas far from human settlements and around mangrove ecosystem, while the lowest abundance is in area near residential settlements and ports. Simple linear regression relationship between organic matter and the abundance of phytoplankton in Sungai Guntung estuary has a moderate relationship, where the correlation coefficient (r) = 0.36. The relationship between organic matter and phytoplankton abundance is negative, the higher the value of organic matter, the lower the abundance of phytoplankton..

Abstract

The study on diatom epipelic has been conducted in Cawan Island coastal waters of Indragiri River’s estuary, Riau Province. The main purpose of this research was to learn the community structures of epipelic diatom and water quality conditions. The method used were consisting of field survey and data gathering from related parties. The epipelic diatom samples were collected by using 5x5 cm2  plots. Diatom samples and water quality analysis were done in Marine Biology Laboratory of Faculty of Fishery and Marine Science. The results showed that community structures of epipelic diatom had intermediate level of contaminant. The 2 indexes, i.e.the diversity index (H’) and the eveness index (E’), were calculated at the values of  2.768 and  0.499, respectively. As for the dominant index (D) the value was at 0.176. Most of the parameters value of water quality (chemical and physics) were in the range of the aquatic organisms life. Statistical analysis showed the abundance of epipelic diatom between station were relatively similar. Keywords: Diatom Epipelic, Estuary, Coast, Cawan Island

Abstract

community needs and demands, planned, implemented (if feasible), controlled and evaluated with the community. One of the alternatives that has been proposed to solve the problem of waste in various regions in Indonesia is the garbage bank. The construction of garbage bank is the initial momentum to build collective consciousness of the community to start sorting, recycling, and utilizing garbage because garbage has good selling value, so that environmentally sound waste management becomes new culture of Indonesia. This study aims to analyze community-based waste management through waste bank programs in Pekanbaru and analyze the relationship of waste bank management to environmental, economic and social impacts. The research was conducted at garbage bank of Dalang Collection and BerlianLabuai with 142 respondents. Data collection was done by observation, interview, and questionnaire. Data analysis techniques using descriptive analysis techniques and product moment correlation. From the result of research, the correlation between variable X (waste bank management) and Y (environmental, economic and social impact) is 0,660, and contribution of waste bank management to environmental, economic and social impact is 43,56%. Based on the result of t test analysis obtained tcount (10,39)>ttabel (1,645). Thus it can be concluded that there is a significant relationship between waste bank management on environmental, economic and social impacts.
