Environmental quality management must consider both public perceptions and actual environmental conditions. This study presents an integrated approach combining community perceptions and pollution source mapping to enhance sustainable river water quality management. This study aims to identify the distribution of pollution sources and assess community perceptions of the Bedadung River’s water quality in Jember Regency. The research involved compiling a pollution source inventory, distributing questionnaires to respondents, mapping pollution sources, and conducting data analysis. Water quality parameters observed included Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Coliform (TC) for the period 2016–2019. Sampling was conducted at five monitoring stations located across three sub-districts: Patrang, Sumbersari, and Kaliwates. A total of 400 respondents participated in the study. The findings indicate that pollution sources in the Bedadung River consist of 81% domestic, 10% agricultural, and 9% industrial inputs. Additionally, the measured BOD, COD, and TC levels exceeded the Class I water quality standards specified in Indonesia’s river water regulations. Based on community perceptions and considering the distribution of pollution sources, 58% of respondents perceived the river as polluted, while 42% considered it to be in good condition. These results highlight the importance of integrating scientific monitoring, community perception improvement, and environmental health mapping to support sustainable water quality management in the Bedadung River.

This study highlights the urgency of addressing the increasingly complex issues of flooding and tidal inundation (rob) in Pekalongan City, where existing mitigation efforts have not yet yielded optimal results. The aim of this research is to identify the problems in flood and tidal inundation management from the community’s perspective, particularly in the aspects of infrastructure, human resources, institutions, and systems. This study employs a qualitative research design. Data were collected through in-depth interviews conducted with key community actors across eleven urban villages affected by flooding and tidal inundation in Pekalongan City. Data analysis was carried out using content analysis techniques, including stages of data reduction, categorization, and interpretation of meanings based on similarities in empirical findings. The results indicate that four main aspects contribute to the suboptimal flood and tidal inundation management efforts in Pekalongan City, namely infrastructure, human resources, institutions, and systems. The infrastructure aspect highlights issues related to the suboptimal function, equity, and maintenance of flood and tidal control facilities. The human resource aspect emphasizes problems of low awareness, participation, and community capacity in mitigation efforts. The institutional aspect points to weak coordination among stakeholders, as well as a lack of transparency and public participation. The system aspect reveals problems with early warning and aid distribution mechanisms that remain unintegrated and ineffective. The findings imply the need for a reformulation of sustainable strategies for flood and tidal inundation management through improving the quality and equity of infrastructure, enhancing community adaptive capacity, strengthening cross-sectoral and interregional coordination, integrating spatial data-based early warning systems, and controlling spatial utilization based on adaptive and mitigation-oriented spatial planning principles.

Local knowledge in identifying, utilizing, and processing Dioscorea hispida (gadung) constitutes an important yet often overlooked component of rural food security. This study examines how such knowledge is produced, maintained, and practiced by communities in Darmaraja District, Sumedang Regency, West Java. A qualitative approach was employed through in-depth interviews and field observations involving eight informants with varying degrees of experience in gadung utilization. The findings reveal that local communities possess detailed ecological knowledge that enables them to identify gadung based on morphological characteristics and seasonal harvesting cycles, particularly during the dry season. Despite its natural cyanide content, gadung is rendered safe through a complex, multi-stage detoxification process, including slicing, drying, soaking, repeated washing, and steaming, which may take up to 9–10 days. This process demonstrates not only technical expertise but also embedded cultural values such as patience, risk awareness, and intergenerational knowledge transmission. Beyond subsistence, gadung contributes to rural livelihoods through small-scale economic activities, particularly in the production of chips, while also reflecting gendered divisions of labor in resource management. Moreover, gadung carries symbolic meanings embedded in oral traditions and local expressions, indicating its broader role within the cultural system. This study argues that local knowledge surrounding gadung represents a multidimensional knowledge system that integrates ecological adaptation, economic resilience, and cultural meaning. As such, it plays a critical role in strengthening sustainable food security by enabling communities to utilize marginal and potentially hazardous resources in adaptive and culturally embedded ways.

The impact of the COVID-19 pandemic is in the past, and it is evident that the environmental impacts of tourism, especially in inner areas with fragile ecosystems, are even more intense, especially in tourism metropolitan areas like the Bangli Regency, which is characterised by highlands, farming systems, and protected areas. This work attempts to explore and describe the impacts of the development of ecogastronomy in Bangli Regency, concentrating on the management and impacts of natural resources, pollution and waste, ecosystems and wildlife, and climate change. The researchers utilised a qualitative case study with in-depth interviews, constructivist observation, document review, and thematic analysis using NVivo. For the climate change impacts analysis, the researchers employed ISM as a qualitative paradigm. The study found that while awareness and conservation from overexploitation of resources and pollution are constructive, many risks are associated with the disturbance of the ecosystem. ISM emphasised natural resource management and climate change as two primary systemic elements that override the ecosystem. It was found that the development of ecogastronomy has the potential to promote environmental sustainability, especially with coordinated integrated environmental management, and that eco-gastronomy is an inner tourism.

White leg shrimp (Penaeus vannamei) is one of Indonesia's leading commodities with high economic value. The growth of white leg shrimp can be influenced by internal and external factors. Internal factors can include genetics, while external factors are dominated by feed and the environment. Feed costs in aquaculture account for 60-70% of total production costs. Raw materials that are sources of protein for shrimp feed include fishmeal, meat bone meal (MBM), poultry meat meal (PMM), and soybean meal. Maggots (Hermetia illucens) are insects that can replace imported fishmeal. Maggots contain 43.42% protein, 17.42% fat, 18.82% crude fiber, 8.70% ash, and 10.79% moisture. This study aims to determine the effect of maggot meal formulated as artificial feed on the growth performance and survival of white leg shrimp (P. vannamei). The method used is a completely randomized design (CRD) with 5 treatments and 4 replicates: (A: 0% maggot meal, B: 25% maggot meal: 75% fish meal, C: 50% maggot meal: 50% fish meal, D: 75% maggot meal: 25% fish meal, and E: 100% maggot meal). The results showed that the best utilization of maggot meal was obtained in treatment D, where the absolute weight gain (1.83 g±0.02), specific growth rate (3.90%), feed conversion ratio (3.64±0.10), and survival rate ranged from 97.5 to 100. Water quality values remained within a range suitable for white shrimp survival

Human activities are believed to have caused significant damage to ecosystems. In fact, a healthy ecosystem must always be maintained so that it can continue to provide its services to humanity. The research aims to assess the health of the coastal ecosystem in Palu Bay, Central Sulawesi. Ecosystem health is measured by establishing an ecosystem health index (EHI) using McKinnon's framework for environmental health. The indicators set to measure the EHI are, first, the habitat (coastal water connectivity, mangrove forest stand condition, and pollution/clarity). Second, the biological resources/species (catch diversity and catch quantity). Third, the socio-economic conditions (fishermen's income and willingness to participate in coastal ecosystem management). Overall, the obtained EHI value is 0.47. The index falls into the moderate category. However, three indicators fall into the poor category, i.e., pollution, mangrove forests, and fishermen's income. To improve this health index, long-term efforts are needed, including, first, maintaining the integrity of the coast by reducing physical development; second, raising environmental awareness about cleanliness; third, implementing rules for the use of fishing gear and environmentally friendly fishing methods; and fourth, strengthening environmental awareness among the society.

Character formation in environmental management requires a structured and sustainable habituation mechanism embedded in students daily school practices. This study aims to analyze habituation as a strategic mechanism for character formation in KALINGGA based environmental management atSMP Negeri 39 Semarang. The study employed a descriptive qualitative approach involving KALINGGA advisors as key informants, KALINGGA members as primary informants, and non-KALINGGA students as supporting informants. Data were collected through in-depth interviews, participatory observation, and documentation, then analyzed using the interactive model of Miles, Huberman, and Saldana. The findings reveal that KALINGGA based environmental pratices through five operational divisions, including innovation, waste management, water and energy conservation, and tree maintenance. Through continuous interaction supported by cultural, social, and symbolic capital, these repeated practices gradually develop into an environmental habitus among students. The study concludes that environmentally resposible character is formed not only through cognitive understanding, but through the integration of habituation, capital, and social arena within everyday school environmental management
