The plastic waste emergency in Denpasar reflects an ecological and social crisis due to the accumulation of single-use plastics. In response, the Bali Provincial Government issued Governor Regulation No. 97/2018, though its implementation remains limited. This study analyzes forms of community resistance to the policy and identifies structural causes and implications. Using a qualitative approach grounded in Cultural Studies, the research reveals resistance in passive, symbolic, and active forms, driven by information asymmetry, economic burdens, and lack of participatory policy-making. Findings show resistance as an articulation of agency within power/knowledge relations. The study concludes that environmental policy success depends on authentic public engagement as subjects of change.

Hasil penelitian menunjukkan bahwa kedua negara memiliki kebijakan nasional sebagai langkah penanggulangan permasalahan sampah plastik, di Indonesia diatur dalam Undang-Undang Nomor 18 Tahun 2008 dengan prinsip 3R, sedangkan Thailand dengan Peta Jalan Pengelolaan Sampah Plastik 2018-2030. Melalui pendekatan studi pustaka, penelitian ini mampu memberikan sumbangan akademis berupa pemetaan kebijakan dan evaluasi implementasi program yang telah dilakukan di masing-masing negara, sebagai dasar penyusunan strategi pengelolaan sampah plastik yang lebih efektif dan berkelanjutan.  

Coffee production generates large amounts of solid waste, particularly coffee pulp, which can lead to environmental pollution if not properly managed. This study investigates the utilization of coffee pulp waste as a liquid organic fertilizer (LOF) and its effect on the growth of Arabica coffee seedlings (Coffea arabica L.). The experiment was conducted using a randomized complete block design (RCBD) with five treatments (0, 10, 20, 30, and 40 ml/L of LOF) and five replications. Observations were made on seedling height, stem diameter, and number of leaves over a four-month period. The results showed that the application of LOF had a significant effect on plant height and number of leaves. The highest increase in height and leaf count was observed in the 30 ml/L treatment, while the 40 ml/L treatment showed a slight decline, possibly due to nutrient oversaturation. However, stem diameter did not show a statistically significant difference among treatments. Correlation analysis indicated a strong positive relationship between plant height and leaf number (r = 0.800), suggesting synchronized vegetative growth. These findings demonstrate the potential of coffee pulp LOF as an eco-friendly alternative to chemical fertilizers in coffee seedling nurseries. Further research is recommended to evaluate long-term effects and optimal dosages for different growth stages.

The growth of population and rapid urbanization in metropolitan areas have triggered a significant increase in waste volume, including in the city of Bandung. This study aims to analyze the implementation of waste management policies using the Soft System Methodology (SSM), particularly through the CATWOE analysis framework. The research was conducted in three sub-districts with distinct characteristics—Coblong, Arcamanik, and Cinambo through in-depth interviews with key stakeholders and field observations. The findings reveal that programs such as Kang Pisman and TPS3R face major challenges related to public participation, cross-sectoral coordination, and limited resources. The CATWOE analysis identifies the need for system improvement by considering the perspectives of all stakeholders: the community (Customer), technical implementers (Actor), policy makers (Owner), and external environmental factors (Environment) that influence the effectiveness of waste management policies.

Reda dragon fruit (Hylocereus polyrizhus) peel, which is often discarded as waste, contains pectin that has potential to be used in the food industry.  This review article aims to examine the effect of microwave-assisted extraction (MAE) technology on the results of pectin extraction from red dragon fruit peel. A review was conducted on four main scientific articles discussing MAE for pectin extraction from dragon fruit peel, focusing on the chemical composition aspect and the effect of MAE technology on the extraction results. MAE technology has been shown to significantly increase extraction efficiency compared to conventional methods, with parameters such as pH, extraction time, and solid-liquid ratio affecting the extraction results. One potential application of dragon fruit peel pectin is as a base material for environmentally friendly edible films with functional added value. Formulation optimization and further testing are needed to develop the application of dragon fruit peel pectin on an industrial scale.

Waste is a problem that needs attention because it can have a negative impact on the environment and human health. Medan City, including North Sumatra, has a waste management problem that has not been optimized. One of the landfills in Medan City is Terjun Landfill. Air pollution in the Terjun landfill area of Medan City is a serious problem that affects the quality of life of the surrounding community. This study aims to assess the community's perception of air pollution in the area, identify their level of awareness of the impact of air pollution, and assess community participation in pollution control efforts. The research method used is qualitative with data collection through interviews and direct observation to residents living around Terjun landfill. The results showed that the community is aware of air pollution from landfill activities, especially the unpleasant odor that is more pronounced at night and the smoke from burning waste that disturbs respiratory health. The community also considers that this air pollution has a negative impact on their health, such as respiratory problems and decreased quality of life.  

Structural poverty is a complex phenomenon that occurs due to systemic inequality in economic, social and political structures, which traps marginalized groups in a cycle of poverty that is difficult to break. This research aims to analyze the impact of structural poverty on waste pickers in the Bintara Jaya slum, West Bekasi, focusing on internal and external factors that reinforce the cycle of poverty. The research method uses a descriptive qualitative approach through in-depth interviews with five waste picker informants. The results show that structural poverty in the waste picker community is influenced by limited access to education, informal work with unstable income, inadequate living conditions, and the lack of government policy intervention. Internal factors such as low levels of education and skills, as well as external factors such as social stigma and non-inclusive policies, exacerbate the condition. Despite facing severe challenges, the waste picker community still has hope to escape poverty, especially through their children's education. This research recommends the need for more holistic and inclusive policies to break the cycle of structural poverty, including improved access to education, skills training, and social protection for marginalized communities.
