The purpose of this research was to determine the amount of waste in TPA Puuwatu and the volume of methane gas produced. It used a quantitative descriptive method with data obtained from related institutions, such as the Sanitation and Parks Office and the Central Statistics Agency. The survey location was TPA, which is a Final Waste Processing Site, Puuwatu in Kendari City.. The results showed that the average volume of waste from January to July 2018 was 5,278 m3, though the total was 32,667m3 with potential waste (Q) of 184.503,216 kg/day. The volume of methane gas produced was 15,360.3062 m3/day.
Mining port operations are complex and can cause various forms of pollution. Analysis of seawater pollution from mining ports is required and complicated because of the various types of pollution, sources, effects, and different characteristics. This study examines the content of heavy metals in seawater in residential areas very close to mining ports. The method used sampling in three different places, examining seawater’s heavy metal properties. Secondary data of the quality of seawater was obtained from the results of data monitoring carried out by the company periodically since the port was built as a comparison material from the results of sample inspection. The results of this study indicate that the waters around the settlements contain heavy metals. The composition of Cd was 10%, Pb was125%, Cu was 625%, Ni was 760%, and Zn was 300% above the standard of seawater quality for the Port Area set by the Indonesian government, which did not match the yearly reports (secondary data). On the other hand, community activities also have a minor role as a source of pollution. Therefore, it is essential to do further research with a focus on finding sources of pollution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
