Increased human activity towards the water bodies will change the condition of water quality. Case study in Langsa, Aceh, It was found that an increase in Some physical parameter (TSS) that exceeds the value determined in PP 82 of 2001 (Indonesian government standard). The high value of TSS in Station 2 and Station 3 indicates that the sediment loading to the water body is high, especially in Station 3, where the TSS concentrations far exceed the standard. Activity of type C surface mining materials tends to affect the brightness, turbidity, depth and TSS. Water conditions with low pH were also found in this study. In location studied no EPT larvae were found Keyword: Langsa, Water Quality, Stream, Total Suspended Solid, Anthropogenic Activity

Alberta Oil Sands

Geotechnical engineering embraces soil mechanics, rock mechanics, and engineering geology. In practice it employs a wide variety of techniques ranging from site mapping and characterization to advanced theoretical analysis and performance monitoring. This paper draws on the development of the Alberta oil sands as a case study to illustrate the breadth of application of geotechnical engineering in large-scale resource developments.A description of the resource base and common extractive procedures used in the Alberta oil sands is given. The geological setting and geotechnical characterization of the Athabasca deposit are summarized. Detailed discussions are presented on geotechnical contributions to surface mining and slope stability, waste handling and tailings dam construction, and in situ recovery processes. The substantial opportunities for geotechnical engineering to contribute to both safe and economical operations in the extractive industries are emphasized. Key words: oil sands, mining, slope stability, monitoring, dredging, shear strength, tailings dam, overburden, liquefaction, pore pressures, geotechnical engineering.

The Village

This study provides insight into the attitudes and perceptions of people who live alongside dingoes in a remote Australian mining town. A mixed-methods, self-administered questionnaire was circulated, targeting employees across 11 departments (n=160). Overall, employees saw dingoes favourably (60.5%), and believed that humans and dingoes should be able to coexist (75.8%). Dingoes were not considered to be causing unacceptable damage or to be overabundant, despite being seen almost daily at both the village and work sites. A total of 31.4% of employees had felt threatened or scared because of a dingo on more than one occasion, and 16.5% had experienced a dingo being aggressive towards them at least once. Yet, only 21.0% of employees considered dingoes dangerous to people, and few worried about their safety at the village or work site (9.5% and 11.4% respectively), or the safety of others in general (21.6%). There was a dichotomy of views regarding the dingo’s presence: employees were supportive of dingoes living in close proximity at the mine, as long as they were not directly being problematic (i.e. representing a personal threat, or causing property damage). Half of the employees surveyed (50.4%) felt that management decisions relating to dingoes were personally important to them, highlighting the need to ensure that employees are consulted, and that dingo management strategies are well communicated. These findings have implications for improving the success rates of management approaches to human–carnivore conflict at mine sites and other situations where predators are perceived to threaten human safety.
