Environmental education enrole strategically in changing human perception andattitude on the environmental problem in the long run. The current study attempt to analyzeenvironment awareness among the high school students in the village, small city and big cityand that factors affecting the awareness. Apparently, knowledge, attitude and behaviourpartially do not influenced environmental awareness of the student in the school obtainingadiwinata and with that non-adiwinata. However, simultantly, student attitude had an effectto student awareness of adiwiyata school, while in non adiwinata school both attitude andbehaviour influenced student awareness.
The research was conducted from March to June 2015 during the rainy season and the Village were located in four Selatpanjang South Village, East Selatpanjang, Selatpanjang City and West Selatpanjang Tebing Tinggi District of Riau Kepulauan Meranti. The purpose of this study was to analyze the potential availability of rainwater, water needs population in the region Selatpanjang 2030, the development of rainwater harvesting systems and outlines the relationship with environmental, social and economic. The method used in this study was the observation by analyzing rainfall, debit mainstay, drainage coefficient (α), population projections, the ratio of the number of residents with clean water needs as well as rainwater harvesting design. The results showed that the potential of rainwater in the area amounted to an average Selatpanjang 1724.8 mm/year, of the four sub regions Selatpanjang rain water can be harvested amounted to 17.248 billion liters/year. The four village Selatpanjang region in 2030 amounted 49 471 inhabitants population in predicted, so, it is necessary to clean water for 534 286 800 liters for three months. So if managed and well developed, the rain water can meet the need of clean water Selatpanjang community throughout the year. How to manage it is by developing the rainwater harvesting system with a system of individual, communal for three families and communal for five families and build ponds to accommodate the run-off. Economically, the use of rainwater harvesting system is cheaper than buying water each summer, primarily communal system for three families. Socially aspects that bring positive habits and reduce conflicts between neighbors and the environment, with the principle of sustainable utilization of natural resources. The quality of rain water in Selatpanjang meets the criteria for clean water, so it can be used as a source of clean water.
Waste is a wasted or intentionally disposed material derived from the results of human and natural activities that do not have economic value. Pekanbaru city is one of the city that does not escape from garbage problem. The waste management of Pekanbaru City includes the final collection, collection, transportation, processing and disposal. Current waste management has not solved the problem optimally. The concept of waste management conducted by urban community Pekanbaru at this time mostly only tn the conte.xt of transporting waste from waste sources to landfills (FPA) which then will have an impact on the environment and health around the TPS are supported also with the behavior of people who are still mixing between dry waste and wet garbage. Type of research is done by qualitative approach with descriptive method Based on field facts with data collection techniques include observation, interviews, docwnentation studies related to research objectives. This research uses Hartono theory which mentions 5 stages of the applied process, namely prevent, reuse, recycle, capture energy and waste. The informant of this research is the administrative staff of Garbage Management Sector Pekanbaru City, Section Head of Solid Waste Management of Domestic Riau Province, and Chairman of Swadaya Masyarakat "Tarai Mandiri". For the purpose of this research is to analyze the waste management of Pekanbaru City and to know the factors - factors that influence waste management Pekanbaru City. The results of research conducted by researchers can be concluded that waste management Pekanbaru not yet maximal, this is based on the concept of waste management that is still not running optimally to change the old waste management concept to the new management concept using 3R concept (reduce, reuse and recycle) conducted by the government. This is influenced by the lack of public awareness and kuranngnya infrastructure facilities as a tool in the process of waste management
This study was conducted in March 2020 located in Muara Sungai Batang Apar North Pariaman District Pariaman City of West Sumatra Province. The aimed of the study is to find out the amount of density, biomass, carbon stock and CO2 uptake, as well as to know the relationship of density with biomass, carbon stocks and CO2 uptake. The method used in this study is a method of surveying and analyzing samples conducted in the Marine Chemistry Laboratory of the Department of Marine Sciences Faculty of Fisheries and Marine, Riau University. The average number of mangrove upright densities in the study area at all three stations was 1.407,41 ind/ha, the average amount of mangrove biomass is 666,97 tons/ha, the average amount of mangrove carbon stock is 313,52 tons/ha, the average amount of soil carbon stock is 2.561,90 tons/ha and the average amount of CO2 uptake is 1.149,56 tons/ha.
This research was conducted from Maret until June 2008, in Big Hall of Development Marine Aquaculture Lampung. The research used experimental methodology, with 4 treatments and 3 replications. The aimed of research are to know effects of vitamin C to increase a haemoglobin of blood and survival rate and measured effective C vitamin in prawn of humback grouper. The result showed that the highest haemoglobin rate of at PC (2 g/kg prawn), equal to 0,915 g/100 mL. The lowest haemoglobin found at treatment PA. equal to 0,066 g/100 mL. Result of variansi analysis indicate that addition of vitamin C at food give influence to increase the haemoglobin rate (P<0.05). Survival rate after experiment are 100 %. Parameter of water quality of were: temperature 29.3-30.2 o C, pH 7.81-8.27, salinitas 31-32 psu, DO 3,65-5 mg/L, and ammonia content (NH 3 ) 0.044-0.069 mg/1
