Abstract

The development of tourist destinations with a community-based tourism approach is one form of alternative tourism that has the potential to be carried out. Tourism destination development activities carried out by the community often unknowingly have implemented a community-based tourism approach, as happened in the tourist destination of Siwang Village, Ambon City. Through a qualitative methodology, this study found that the people in Siwang Village have successfully implemented a community-based tourism approach to develop their tourism potential and attractiveness. Siwang Village is one of the mountainous tourist destinations in Ambon City, Maluku Province, which has been successfully managed independently by optimizing its potential and human resources. This research was conducted in 2021 by making the community key informants and policy makers and tourists additional informants.

Abstract

Background: Motor vehicle activity in shopping mall areas is a primary source of carbon monoxide (CO) emissions, posing a potential long-term health risk for workers with sustained exposure. This study aimed to conduct an environmental health risk assessment of CO exposure for traders operating in the Jumbo Supermarket Area of Manado City. Methods: An observational study with a quantitative approach was conducted in July-August 2025. Ambient air CO concentration was measured in real-time using a CO meter at three location points, with purposive sampling of 30 traders. Respondent characteristics, including exposure parameters, were collected via questionnaire. Health risk analysis was performed by calculating the Average Daily Dose (ADD) and Risk Quotient (RQ), following the US EPA (2022) guidelines, where an RQ > 1 indicates an unacceptable non-carcinogenic risk. Results: The mean ambient CO concentration was 1,591.89 µg/m³, which is significantly below the national air quality standard (10,000 µg/m³) set by Indonesian Minister of Health Regulation No. 02 of 2023. The risk assessment yielded average RQ values of 8.38 x 10⁻⁵ for real-time exposure and 1.23 x 10⁻⁵ for lifetime exposure. All calculated RQ values were substantially below the safety threshold of 1. Conclusion: Current CO concentrations in the study area do not exceed regulatory standards and do not pose an unacceptable non-carcinogenic health risk to traders. However, implementing periodic air quality monitoring is recommended to ensure the continued protection of worker health in this environment.

Abstract

Background: Acute Respiratory Infections (ARI) remain the primary cause of morbidity among children under five in Indonesia, with the domestic physical environment being a significant determinant. Surveillance data from the Tuminting Health Center (2025) indicates an exceptionally high prevalence of ARI (79.0%) in toddlers within Tuminting District, Manado City. Objective: This study aimed to analyze the association between residential occupancy density and house ventilation area with the incidence of ARI in toddlers in this high-prevalence region. Methods: A cross-sectional study was conducted from July to November 2025. A purposive sample of 62 toddlers was enrolled. Primary data were collected via questionnaires, direct observation, and physical measurements of dwellings using a roller meter. Univariate analysis described variable characteristics, and the Fisher's Exact test was employed for bivariate analysis with a significance level of p < 0.05. Results: The majority of households had non-compliant occupancy density (83.9%), while most had adequate ventilation area (91.9%). The ARI prevalence was 79.0%. Bivariate analysis revealed a statistically significant association between high occupancy density and ARI incidence (p-value = 0.004). In contrast, no significant relationship was found between ventilation area and ARI (p-value = 0.280). Conclusion: Occupancy density is the dominant environmental risk factor contributing to the high incidence of ARI in toddlers in Tuminting District. These findings underscore that public health interventions must extend beyond improving physical housing quality (e.g., ventilation) to actively address overcrowding through healthy housing policies and targeted community education.

Abstract

Freshwater scarcity remains a critical challenge in small island regions, particularly in archipelagic countries such as Indonesia, where seawater is abundant but access to clean freshwater is limited. Tunda Island, located in Serang Regency, Banten Province, exemplifies this condition, as local communities primarily depend on rainwater harvesting and shallow groundwater sources to meet daily water demands. This study aims to evaluate a modified reverse osmosis (RO) desalination system integrated with coconut shell–based activated carbon as an adsorptive pretreatment medium for seawater desalination. The coconut shell adsorbent was employed to enhance pretreatment efficiency and improve the overall performance of the RO system. Seawater samples collected from Tunda Island were processed through the integrated system, and the quality of the treated water was evaluated according to the Indonesian Ministry of Health standards. Key parameters analyzed included Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), pH, color, and temperature. The results demonstrated that the treated water achieved COD of 120.10 mg/L, BOD of 10.5 mg/L, TSS of 3.76 mg/L, TDS of 117.245 ppm, pH of 7.30, clear color, and a temperature of 27°C, indicating compliance with applicable water quality standards. These findings confirm that the integration of coconut shell–based activated carbon with reverse osmosis effectively improves desalination performance and produces freshwater suitable for domestic use.

Abstract

Puncak Dunu nature tourism in North Gorontalo Regency has strong potential for local economic development but has not been managed optimally or sustainably. This study aims to analyze destination conditions based on the 5A components, examine tourists' perceptions, and formulate sustainable development strategies. A mixed-methods approach was applied using field observations, questionnaires to 100 respondents, and in-depth interviews with key stakeholders. The results show that natural attractions and special-interest activities are the main strengths, while amenities, accessibility, and ancillary services remain limited. Tourist perceptions are generally positive, yet revisit intention is low, with 52 percent of visitors visiting only once. SWOT analysis through IFAS and EFAS places Puncak Dunu in Quadrant I, indicating that an aggressive Strength–Opportunity strategy supported by a master plan is required for sustainable destination management.

Abstract

Climate change due to drastic increases in greenhouse gas (GHG) emissions has damaged marine ecosystems through warming and acidification. This study aims to analyze the conformity of international law and the implementation of Indonesian national regulations in an effort to protect the marine environment from the impacts of anthropogenic GHG emissions. Using normative legal research methods, this study applies legislative and conceptual approaches to examine UNCLOS 1982, the Paris Agreement, the Environmental Management Law, and Presidential Regulation No. 110 of 2025. The results show that Article 192 of UNCLOS 1982 is now interpreted as a due diligence obligation that requires states to make maximum efforts to prevent marine pollution, including emissions released into the atmosphere. At the national level, Indonesia has made significant reforms through Presidential Regulation No. 110 of 2025 which allows for accelerated carbon trading without having to wait for the achievement of NDC targets. In addition, the enactment of Ministerial Regulation No. 1 of 2025 strengthens the technical governance of blue carbon as a mitigation instrument and economic asset. The study concludes that Indonesia has built a responsive legal foundation by integrating the Economic Value of Carbon into marine environmental protection. The implementation of MRV mechanisms and emissions certification demonstrates the state responsibility to fulfill international commitments. This legal harmonization is a prerequisite for slowing marine ecosystem degradation, safeguarding marine biodiversity, supporting food security for coastal communities, and advancing intergenerational environmental justice.  Nevertheless, consistency between economic acceleration and ecosystem integrity remains necessary to ensure sustainable marine conservation.
