Abstract

The operation of the Talangagung Edu-Tourism Landfill applies a sanitary landfill system, which requires a workforce  to operate  optimally. These workers may be exposed to work  accidents and occupational diseases when the Landfill is operating, which come from various sources of OHS hazards. Efforts to reduce the risk of work accidents and occupational diseases consist of managing  OHS in the working  environment of the Talangagung Edu-Tourism Landfill. The goal of this study is to evaluate the application and provide recommendations to  improving the application of OHS management at  the Edu-Tourism Landfill in Talangagung. Thus, the Talangagung Edu-Tourism Landfill can maximize the volume of waste and educational tourism facilities. This study involved 16 respondents who were divided into workers and decision-makers by selective  sampling in the operation of the Talangagung Edu-Tourism Landfill with data collection by observation, interviews, and questionnaires. The results of this study show that the Talangagung Edu-Tourism Landfill has implemented OHS management but the need to formulate new OHS management, to achieve  maximum results. The priority strategy in efforts to improve OHS management is to "enhance  awareness of OHS management" where there is a plan to implement  the strategy to facilitate  implementation of  the strategy in the work environment.

Abstract

This study chitosan membranes were made by phase inversion method by adding rice husk ash silica additives to the casting solution. This study aims to create and evaluate the characteristics of chitosan-silica rice husk ash membranes for application in reducing Cu heavy metals. Chitosan membrane modification is needed to produce membranes with better character, for example increasing membrane stability, reducing pore size so that the separation of molecules or rejection of macromolecules from a membrane solution is more effective. The concentration of chitosan-silica rice husk ash was varied at 20, 19, 17 and 15 (% by weight). The resulting membrane was further characterized for morphological structure parameters by scanning electron microscopy (SEM), fourier transform infrared (FTIR). Flux and solution rejection using dead-end filtration modules. The SEM test results show that the membrane has pores with asymmetric structures. Membrane performance test on Cu metal has a rejection value of 38%, 39%, 46% and 62% with flux gain reaching 0.4135 to 15.4377 L / hr.
