Abstract

The cement industry is one of the most important industries in the development of a country. However, the production activities of the cement industry also cause significant environmental impacts, one of which is air pollution. One of the by-products of fuel combustion in the cement industry is fly ash, which if not managed properly can pollute the air and the surrounding environment. This research aims to provide an overview of the environmental impacts of using fly ash in the cement industry, especially in relation to air pollution. This research uses the literature review method, which is by collecting and reviewing literature or documents related to the research topic. The data sources used in this research are scientific journals, books, and other related documents. Data analysis in this study was carried out by reviewing and examining literature or documents related to the research topic, then summarizing and compiling the results of the analysis into an overview. Based on the results of this study, it can be concluded that the use of fly ash in the cement industry has significant environmental impacts, especially related to air pollution. However, there are several technologies and fly ash processing methods that can reduce the environmental impact of cement industry production activities, such as the use of fly ash as raw material for making lightweight concrete or as raw material for the production of other building materials.

Abstract

Stunting remains a serious public health problem in urban areas. A contributing factor to the high prevalence of stunting in the region is the limited availability of clean water and nutrient-rich foods. In addition, this sub-district is at risk of experiencing a clean water crisis in the future. This study aims to analyze the effectiveness of the integration of rainwater harvesting (RWH) and urban farming to overcome stunting, access to clean water, and food supply in Kalibaru District, North Jakarta. The method used is a social experiment through three processes: community education, RWH installation, and urban agricultural system development. For each process, data collection was carried out through field observations and surveys of 39 respondents. Community knowledge was measured before and after the process through questionnaires, and the results of the integration of RWH and urban farming systems were described. The results showed an increase in public knowledge about the benefits of RWH integration and urban farming. RWH has helped alleviate the problem of clean water availability effectively and economically. Meanwhile, urban agriculture has given communities better access to nutrient-rich foods, which in turn can help reduce the problem of stunting.

Abstract

The global movement in green building development has been going on since the early 1960s. Although initially driven by environmental agendas such as carbon and energy, there is a growing acknowledgment that green buildings can affect Indoor Environmental Quality (IEQ). Many researchers also state that improved indoor environmental quality is associated with better occupant satisfaction. However, some localized green buildings, especially in developing countries, often don’t recognize IEQs and occupant satisfaction as important issues, so they remain unstudied. Therefore, this study aimed to evaluate the performance of IEQ and occupant satisfaction. The analytical methods used were descriptive statistics and regression analysis. The outcome demonstrated that green building standards do not automatically improve indoor environment quality, particularly when the lighting parameter is below the limit values. The analysis findings showed that most respondents expressed their satisfaction with IEQ and significantly influenced occupant satisfaction. In addition, this research contributes to the development of green building evaluation practices that prioritize environmental health and occupant satisfaction

Abstract

The medicines production process in the pharmaceutical industry, especially in herbal medicines, impacts natural resources and environmental pollution. Implementing cleaner production (CP) can be a profitable solution for companies. Stakeholders’ attitudes toward implementing CP are needed to achieve a sustainable pharmaceutical industry. This research was conducted at the Company X, a pharmaceutical industry that produces herbal medicines located in DKI Jakarta Province. This research aims to identify and analyze stakeholder attitudes toward CP as assessed based on knowledge, responses, and practices through a questionnaire. The sample was conducted on 122 stakeholders participating in production and environmental management activities, including the Manager, Supervisor, and Staff. The results show that all stakeholders’ knowledge, responses, and practices have a good average criteria. The most significant number of stakeholders who were respondents were production staff at 37.7%. From the results of this research, it is hoped that all respondents will know the herbal medicine production process and implement CP at Company X.

Abstract

Biomass utilization is believed to bring environmental and socio-economic benefits—PT X coal in a steam boiler. The research method used is a mix of quantitative and qualitative. The concentration of particulates that coal produces is higher than that of sugar cane bagasse. The NOx parameter values produced by bagasse and coal showed insignificant results. Meanwhile, coal boilers with higher temperatures produced higher NOx than NOx from biomass. The distribution concentration of SOx in bagasse biomass is higher than coal SOx emissions. A total of 26 communities agreed to change the use of coal to bagasse biomass. Utilization of bagasse biomass provides income of up to 94,000,000,000. Using bagasse as steam boiler fuel has a more positive impact than coal.
