The pollution of polychlorinated biphenyls (PCBs) waste from PLN electrical activities

PCB waste pollution from PLN (State Electricity Company) electrical activities is a serious problem that affects the environment and public health. This article discusses the sources and impacts of PCB waste pollution, as well as the steps that can be taken to address it. PCB waste originates from transformers, capacitors, and other electrical equipment used by PLN, and it can contaminate the soil, water, air, and surrounding living organisms. The consequences include ecosystem damage, disturbance of ecological balance, health risks, and even economic implications. To tackle this issue, effective waste management technologies such as retrofilling, thermal processes, and sodium processes need to be implemented. Additionally, strict waste management policies and regulations should be established, and public awareness of the dangers of PCB waste should be raised. By adopting these measures, we can mitigate the negative impacts of PCB waste pollution and work towards a cleaner and healthier environment

Risk level of firefighters' activities in DKI Jakarta province: a study of occupational safety and health (OSH)

Fire disasters pose risks to the community but also to firefighters. In dealing with a fire disaster, officers sometimes have to be faced with events that are detrimental to them. The purpose of this study is to carry out a hazard risk assessment and provide suggestions for controlling the hazards faced by firefighters. The research method used is qualitative with a descriptive study design approach, through in-depth interviews and direct observation. The results of the study indicate that there are potential hazards faced by firefighters starting from preparation activities, going to the location of the fire incident to returning to the post. The amount of risk faced is dominated by medium risk, for high risk it occurs during the extinguishing process, and for low risk only when officials receive news of a fire disaster. For risk reduction efforts, the forms of control that can be implemented can be in the form of engineering engineering, administrative controls, and Personal Protective Equipment

Utilization of fly ash and bottom ash waste: a study at PLTU Tanjung Jati B, Jepara, Indonesia

The high energy needs force the massive use of coal. PLTU as one of the largest energy-producing industries currently has a significant impact on the environment and social economy. One of the wastes from PLTU activities is fly ash and bottom ash (FABA). By taking a research study at the Tanjung Jati B PLTU one of the largest PLTUs in Indonesia, the authors try to see the impact of FABA waste on the environment and analyze the potential that can be utilized. The research approach used is quantitative by collecting data through literature studies. The results showed that FABA had a negative impact on the environment, especially when it was only left buried in landfills. On the other hand, FABA has the potential to improve the economy, especially for the people around the PLTU industry, including in the agricultural aspect. One of the benefits of FABA is for building construction purposes with a mixture of 20% to 35%. For agriculture, FABA is proven for soil enrichment on a small scale with a mixture of 35% to 50% and can increase the nutrients in the soil

The impact of jangari reservoir tourism on environmental pollution

oai:ojs2.journal-iasssf.com:article/139The purpose of this research is to learn information about the effects of Jangari reservoir tourism On The Environmental Pollution Surrounding Bobojong Village. This study is conducted on the Jangari Reservoir Located In Bobojong Village, Mande District, Cianjur, West Java. Samples in the study include West Java LLASDP employees, tourist conscious groups, bargas owners, Floating Net Cage (KJA) owners, tourists and other communities. The sampling technique used is purposive sampling. This research conducted by observation to the location, ingrate, and interview of the respondents. The questionaire used consisted of 11 questions in the form of multiple choice and stuffing. The data of further research is analysed in a qualitative descriptive way that aimed at describing the quality of the findings based on the study of the references used. The result of this research shows that even though there is not much visible environmental pollution, indications of environmental pollution are already visible, marked by the presence of piles of garbage at several points, styrofoam waste in the waters of the Jangari Reservoir, boat traffic activity in the waters of the Jangari Reservoir, and water hyacinth growing around it. waters to cover the water surface of the reservoir. Waste management in Jangari Reservoir does not carry out 3R (Reuse, Reduce, Recycle), waste management has involved local communities and the government but the implementation has not been maximized because it is not carried out routinely

Evaluating healthy workplace in geothermal industry

The geothermal industry is located in mountainous areas and far from urban centers that are at risk of danger. Hazard management is one aspect of occupational safety health management, including occupational environmental health. Therefore, this study aims to evaluate the healthy workplace in geothermal industry. Observation and measurement technique are used to determine the light intensity, noise, humidity and temperature in all room in the industry. The results state that there are three rooms that did not meet the standard, the noisy still eligible both for offices (65dBA) and PLTP (85 dBA), the humidity is quite high (60%) and the average temperature is 15-20oC. Most of the indicators are still below the limit value based on the company and local regulations. Pengukuran aspek fisik monitoring kesehatan lingkungan kerja sudah memperoleh hasil yang baik. Namun, masih ada beberapa lokasi lingkungan kerja yang perli dilakukan perbaikan lagi dari segi pencahayaan dengan penggantian jenis lampu LED, dan pengaturan suhu dan kelembapan ruang. The assessment of healthy workplace is needed to improve the well-being of the workers in geothermal industry
