The Citarum River, as one of the important environmental assets in Indonesia, has experienced serious pollution due to industrial waste. Environmental legal regulations have been implemented to address these issues, but questions arise regarding the effectiveness of their implementation. This article analyzes the effectiveness of environmental legal regulations in handling cases of factory waste pollution in the Citarum River, with a focus on the level of industrial compliance and its impact on the environment. This study uses a qualitative approach by reviewing the applicable environmental legal regulations, as well as analyzing the level of industry compliance with these regulations. In addition, the impact of compliance or violations on the environment is also evaluated. The results of the analysis show that although environmental legal regulations exist, their implementation is still not optimal. Many factories still violate the limits that have been set, either because of a lack of strict law enforcement or because of a lack of awareness of the importance of environmental conservation. As a result, the Citarum River continues to experience pollution which is detrimental to the environment and public health. Existing environmental legal regulations are not effective enough in handling cases of factory waste pollution in the Citarum River. More serious efforts are needed from the government, industry and society to overcome this problem. Concrete steps are needed to increase industrial compliance, reduce waste pollution, and preserve the Citarum River environment for the welfare of the community and sustainability of the ecosystem. Further research can be conducted to evaluate the implementation of remedial actions and their impact on future environmental conditions. This article concludes the need for improvement measures in the implementation of environmental legal regulations, including stricter law enforcement and efforts to increase environmental awareness among industry. Apart from that, cooperation between government, industry and civil society is also important to achieve the restoration of a clean and healthy Citarum River.

Coffee is a plantation crop that has long been planted and cultivated in Lombok. Senaru Village, Bayan District, North Lombok Regency is the largest robusta coffee producing area in Lombok with 225 hectares of coffee land. One of the coffee processing places in Senaru Village is the producer of Ayah Senaru Fermented Coffee which still uses the dry sun method with a tool called a widik. This drying method has many disadvantages because it takes a long time, is very dependent on the weather and is unhygienic. The process of drying coffee is the main factor that can determine the quality of coffee, which is why there is a need for technology as a coffee drying medium that is capable of producing quality coffee. Handling after harvest can be improved by applying modern coffee drying technology, namely greenhouses. The aim of this activity is to increase partner profits through an IoT integrated coffee drying greenhouse (GEEOTI) which is able to streamline coffee drying time and produce hygienic coffee skin waste. The method applied is the creation of GEEOTI, socialization of its use and analysis of the impact on increasing partner profits. The results of the research are that greenhouses can have a positive effect in speeding up, flattening the drying process and improving the quality of coffee compared to conventional methods. The waste from the coffee skins produced also becomes more hygienic coffee waste so it can be used as cascara tea. This activity can certainly increase partner profits by up to 100%. The partner's income, which was initially only IDR 5,100,000, was able to become IDR 13,950,000 per month because with the use of GEEOTI there was an increase in the price of coffee and the addition of a by-product in the form of cascara tea from coffee skin waste.

The implementation of environmental law influenced the success of the Eco Town program in maintaining the sustainability of river ecosystems by providing a strong foundation for preserving the environment. The implementation of strict regulations related to environmental protection and river management is key in ensuring that development within Eco Town does not damage the river ecosystem. In several case studies such as the Ciliwung River and the Brantas River, the implementation of environmental law has recorded significant improvements in the sustainability of river ecosystems. The main challenges faced in implementing environmental laws to support Eco Town programs are resource limitations, especially in terms of funds, technology, and natural resources. These limitations may hinder the effectiveness of the program and affect the ability to address environmental problems such as industrial or domestic waste management, and maintain ecological balance. To overcome these challenges, concrete measures such as improved accessibility and technology transfer, sustainable management of natural resources, and investment in environmental infrastructure are needed. By ensuring a solid environmental law implementation and paying attention to these limitations, the Eco Town program can run more effectively and efficiently in maintaining the sustainability of the river ecosystem and realizing a vision of sustainable development.

The Zero Waste concept is a comprehensive approach to waste management that aims to minimize waste production from the early stages of the production process to the end of the product life cycle. The basic principles include the application of the 3R concept (Reduce, Reuse, Recycle), as well as the integration of 4R to 5R principles (Reduce, Reuse, Recycle, Replace, and Replant), which emphasize reduction, reuse, recycling, replacement with environmentally friendly goods, and replanting. By implementing a Zero Waste approach, Indonesia has the potential to reduce the impact of environmental pollution, save natural resources, and encourage more responsible consumption patterns. However, the challenge of implementing Zero Waste in Indonesia requires collaboration between the government, private sector, civil society and international institutions to create an environment that supports Zero Waste adoption.

Hospitals as one of the health service providers cannot be separated from the lives of people who always want to maintain their health. Every hospital must maintain cleanliness because it is a place used as a health facility. Hospital is a type of health service business to the community which certainly produces a lot of waste including hazardous waste in its operational activities. Just like settlements, hospitals also produce a lot of waste and perhaps more. It is difficult to manage B3 waste on their own, so not a few hospitals use B3 waste management services to other parties who of course still have to have a permit from the relevant agency to be able to manage B3 waste. Third parties in managing hospital B3 waste still have responsibilities to the hospital. Government efforts in providing environmental protection and management, and preventing environmental pollution are by providing administrative sanctions, criminal sanctions, civil sanctions. With the sanctions given to people or parties who commit environmental pollution, it is hoped that it can provide a deterrent effect to be better and wiser in managing the waste from their activities in order to preserve the environment and free the environment from pollution.

Bacteria are microorganisms that require adequate media and nutrients to grow and develop. The media commonly used to grow bacteria is Nutrient agar media, but the price of Nutrient agar media is quite expensive. Corn cobs are lignocellulosic wastes that contain nutrients that can meet the nutritional requirements of bacterial growth media. This study aims to investigate the viability of corn cobs as a cost-effective alternative to Nutrient agar media. Specifically, we explore the variance in bacterial colony growth when utilizing corn cobs as a growth medium for Escherichia coli and Staphylococcus aureus bacteria. Employing a true experimental design with a posttest-only control structure, we analyze the treatment's effects using the One Way ANOVA test and Independent Sample T-test. These statistical methods enable us to discern differences between groups utilizing corncob media with and without added sugar.Our findings reveal noteworthy insights into bacterial colony growth. For Escherichia coli, the average number of colonies on corncob media with sugar was 222 CFU/ml, on corncob media without sugar, it was 164 CFU/ml, and on Nutrient agar media, it reached 361 CFU/ml. In the case of Staphylococcus aureus, colonies on corncob media with sugar averaged 871 CFU/ml, on corncob media without sugar, they averaged 657 CFU/ml, and on Nutrient agar media, they reached 942 CFU/ml.Statistical analysis using the One Way ANOVA test for both Escherichia coli and Staphylococcus aureus demonstrated p-values <0.05, signifying significant differences in their growth on corncob media with sugar, corncob media without sugar, and Nutrient agar media. Furthermore, the Independent Sample T-test results for both bacterial strains yielded p-values <0.05, indicating dissimilar growth patterns on corncob media with sugar compared to corncob media without sugar.In conclusion, our study underscores significant disparities in the growth of Escherichia coli and Staphylococcus aureus bacteria among Nutrient agar media, corncob media with sugar, and corncob media without sugar. Notably, we observed a marked increase in bacterial colony counts on corncob media with sugar and corncob media without sugar.
