Abstract

Human activities have had an impact on global warming due to greenhouse gas emissions. Greenhouse gas emissions resulting from industrial activities, transportation and human activities that use fossil energy sources. The purpose of this research is to analyze the increase of air temperature using CO2 and CH4 gas concentration data from 2010-2016, to know the effect of greenhouse gases on the increase of air temperature, and to analyze the most influential factors in increasing air temperature in Pekanbaru and Padang City. The research method used is survey method with assessment and processing of secondary data. The research results found that greenhouse gases in particular the concentration of CO2 gas affect the temperature rise in Pekanbaru and Padang City. The increase of air temperature in Pekanbaru City is 0.52 °C up to 0.61 °C higher than the temperature rise in Padang City 0,51 °C up to 0.60 °C. The correlation of CO2 gas concentration with temperature rise in Pekanbaru City influenced the increase of air temperature by 10.2%. Factors that affect the most increase in air temperature in Pekanbaru City is the number of vehicles and the number of hotspots whereas in the city of Padang temperature rise is influenced by the number of vehicles and the number of industries.

Abstract

The main purpose of this study is to clarify the relation between characteristics of sediments andenvironmental condition based on the analysis of surface sediment samples and total suspendedsediments from the Southern of Bagan Estuary which is located on the East Coast of SumateraIsland, Indonesia. Surface sediment samples and total suspended sediments were collected at 21stations using sediment sampler and van dorm sampler, respectively, in June 2010. The sampleswere analyzed by various analytical approaches i.e. mechanical grain size analysis, ignitionloss method, bulk chemical analysis using atomic absorption spectrometer and sand-graincomposition analysis. In general, the estuary area is characterized by finer sediments (medium-grained sand), by the lower values of organic matters (less than10%), and by the higher contentof Fe and Al per non calcareous clastic content, which is an index of terrigenous material inputrespectively. Concentration of total suspended sediment near bottom is higher than that ofsurface water, indicating sediments turbulented by strong current system. Judging from thedistribution pattern of the Fe and K contents at surface sediment, terrigenous materials weretransported northwestward along the coast of Pekaitan Village and of Barkey Island by strongebb current. Contrastingly, terrigenous materials were transported southeastward along thearea located between coast of Pekaitan Village and of Barkey Island by strong tide current.Geographical distribution of sand grain composition (lithogenous) strongly indicate thatterrigenous materials derived from the hinterland of Sumatera Island discharged through RokanRiver to the Southern of Bagan Estuary. In addition to, terrigenous materials are also resultedfrom coast erosion of Pekaitan Village and of Barkey Island, and turbulented sediments.

Abstract

ABSTRACTThis research was conducted in February-June 2015 in the village of Kesumbo Ampai, District of Mandau, Bengkalis. The research was aimed to identify the forms of Sakai tribe's local wisdom toward forest sustainability and the local wisdom itself and analyze its influence toward the river sustainability concept. The method used in this research was qualitative method that was designed to provide a detailed overview on specific individuals or groups in a particular circumstance and symptom. In order to understand the forms of Sakai tribe's local wisdom, the researcher conducted in-depth interviews with the Sakai community leaders, village heads and the Head of Bengkalis' Culture and Tourism Department. The result showed that Sakai's local wisdom can preserve forests and rivers in their vicinity area. One of the methods used to preserve the forest ecology is by applying a strict land zonification. In regards to the land clearing, the Sakai people keeps using a simple technology until now. For the seeds planting as well, the Sakai people does not work the land and the plants are maintained using organic fertilizers. The simplicity of the technology is a symbol of environmental wisdom. For hunting or fishing at the river, the Sakai people uses traditional equipment that are environmentally friendly so that the river area can be preserved.

Abstract

Compounds that are often used by society in controlling fly populations are chemical insecticides. Inappropriate use of chemical insecticides will harm the environment and human health directly and long term, such as poisoning, respiratory disorders, resistance to insects and environmental pollution. One other alternative to control house flies is organic insecticide that it is basic ingredients come from nature. The purposes of this study were for analyze the effectiveness of organic insecticides in controlling house fly vectors, to determine the concentration of LC 50% organic insecticides to house flies and to find out the impact of organic insecticides on environmental and economic aspects. This study used an experimental method and a completely randomized design (CRD) with four different treatments, namely control, 10% betel leaf extract + 4 ml EM4, 20% betel leaf extract + 4 ml EM4 and 30% betel leaf extract + 4 ml EM4. Each treatment was carried out with three replications. The results of the analysis showed the least amount of mortality of house fly in the control treatment ie one house fly, while the highest average of house flies mortality are 30% betel leaf extract treatment + 4 ml EM4 that are 8.66 house flies. Based on the ANOVA test, the p value <0.05 was concluded that the mean of the four research treatments differed significantly. Based on probit analysis, it was found that the concentration of LC 50% in house flies was 13.09%. Organic insecticide in terms of environment and economy has a positive impact, it can reduce odor in organic waste and has economic value compared to chemical insecticides.
