Abstract

This study aims to examine the disparities in the implementation of the Adiwiyata program in Tarakan City, North Kalimantan, with a focus on environmental curriculum integration and student participation across educational levels (elementary, junior high, and senior high). The study used mixed methods with a sequential explanatory design. Quantitative data were collected through surveys, then further deepened through in-depth interviews, observations, and document analysis in eight Adiwiyata schools. The results show clear disparities across educational levels, namely that program effectiveness increases with school level. Curriculum integration and student participation at the senior high school level significantly influence program effectiveness (β = 0.52; p < 0.05), while at the elementary school level, implementation is still dominated by a physical-administrative approach with instructive student participation. Another finding is that most external school collaboration is more directed at meeting physical indicators and environmental image, rather than strengthening teachers' pedagogical capacity. This study concludes that the success of the Adiwiyata Program is strongly influenced by the suitability of implementation strategies to the characteristics of the educational level. Thus, the need for differential policies that emphasize strengthening teacher ecological literacy at the elementary level, developing meaningful student participation, and evaluating programs based on ecological impacts.

Abstract

This study aims to identify and analyze the relationship between the level of perception and the level of community participation in household waste management in Loa Bakung Village. The research employed both quantitative and qualitative methods using questionnaires, literature review, and direct observation. Respondents were selected using purposive sampling with a total of 80 participants. The results show a p-value of 0.001 ≤ α = 0.05 with a correlation coefficient of 0.361, indicating that there is a correlation between perception and participation in waste management, although the relationship is weak and positive. Qualitative findings reveal that waste banks can help reduce waste volume (66.3%) and highlight the importance of separating organic and inorganic waste (61.3%). However, actual participation remains limited, with only a small proportion of respondents regularly practicing waste sorting, composting, or recycling. The suggested recommendation is the need for awareness programs through KIE (Communicative, Implementation, and Education) approaches and regular monitoring.

Abstract

This study aims to analyze carbon emissions from motor vehicles and the potential for carbon absorption by vegetation on four main roads in Bengkulu City: Padang Jati, Hibrida, Pagar Dewa, and Sukarami. The approach used is quantitative-descriptive, with data collected through traffic surveys and direct measurements of vegetation parameters during the observation period. Emissions are calculated using emission factors based on IPCC/KLHK standards according to vehicle type, while tree biomass is analyzed using allometric equations based on trunk diameter, track length, and vegetation type. Carbon analysis on four roads in Bengkulu City shows a significant imbalance between vehicle emissions and vegetation absorption. Sukarami recorded the highest emissions (751,813 kg CO₂) with a biomass of only 24,053 kg (absorption of 40,607 kg), making it a carbon source. Conversely, Padang Jati had the largest biomass (881,578 kg) compared to emissions of 431,889 kg CO₂, making it a carbon sink with absorption of 344%. Hibrida and Pagar Dewa showed intermediate conditions, with emissions of 424,145–570,063 kg CO₂ and absorption of 544,349–947 kg, indicating an unbalanced absorption capacity. These results emphasize the need to increase vegetation cover and manage green spaces as strategies for mitigating urban climate change.

Abstract

This study aimed to identify key factors influencing the success of hypertension control programs, with a focus on patient compliance and perceptions of program personnel and supervisory performance.A cross-sectional analytical study was conducted involving 80 hypertensive patients from Ampenan and Pejeruk Puskesmas, selected through purposive sampling. Data were collected using structured questionnaires. Chi-square tests were used for bivariate analysis, and binary logistic regression identified the most influential factor. Three variables entered the multivariate model: patient compliance (p = 0.009), perception of program personnel (p = 0.155), and perception of supervisory performance (p = 0.001). Only supervisory performance perception remained statistically significant in the final model (p = 0.001; OR = 5.748; 95% CI = 2.012–16.420), indicating it as the dominant factor even after adjustment for compliance.Supervisory performance strongly influences program success. Strengthening supervision quality and communication within puskesmas is essential to improve patient adherence and the overall effectiveness of hypertension management.

Abstract

This study aims to assess the diversity index, relative abundance, and evenness of soil insects in the Hutan Desa Serdang, Tahura Area, Karo District, North Sumatra. The methods used include pitfall traps and bait traps with a purposive sampling approach at three observation stations: primary forest, secondary forest, and pine forest. The results show that a total of 1,427 insect individuals were found, comprising 8 orders, 13 families, and 20 species. Odontomachus brunneus exhibited high relative abundance, followed by Entomobrya handschini and Solenopsis invicta, which fall into the category of moderate relative abundance. The diversity index of soil insects is categorized as moderate, with an value of H' = 2.0, indicating a balanced ecosystem with a sufficient variety of species. Meanwhile, the evenness index of soil insects is classified as high, with a value of H'= 0.7. This indicates a uniform distribution of species without particular dominance, thus supporting ecological balance and good soil ecosystem quality.

Abstract

This study aimed to identify biological and contextual determinants influencing maternal referral delays at Praya Regional Hospital, Central Lombok Regency. Referral delays significantly contributed to increased risks of maternal complications and mortality, particularly in areas with limited access to healthcare services. A quantitative cross-sectional design was used, and the sample included 95 pregnant women referred to Praya Hospital. Data were obtained through a structured questionnaire and analyzed using Chi-Square tests and binary logistic regression to determine associations between variables and to identify the most dominant factor. The analysis showed that administrative barriers had a significant association with referral delays (p = 0.001), while other variables such as trust (p = 0.383), healthcare provider readiness (p = 0.084), and indirect costs (p = 0.005) showed no significant associations. Administrative barriers were identified as the strongest determinant, with an odds ratio (OR) of 8.037 (95% CI: 3.044–21.221; p = 0.000). To accelerate maternal referral processes, simplifying administrative procedures and implementing digital systems such as SISRUTE were strongly recommended. Further studies are recommended to evaluate the effectiveness of technology-based referral system reforms in reducing maternal mortality rates, especially in resource-limited settings.

Abstract

This study aims to isolate, identify, and test the potential of native lipolytic bacteria from LCPKS contaminated soil, as well as to determine the effect of supplementation of oil palm leaf midrib extract on its degradation activity. The research method uses an experimental design with isolation techniques and morphological characterization of bacteria, followed by a lipolytic test on Nutrient Agar Fat (NAL) medium and a bioremediation test using oil palm leaf midrib extract at concentrations of 0.1%, 0.5%, and 1%. The results showed that there were nine types of colonies with three dominant bacteria, namely Candida spp. (95 colonies), Streptomyces sp. (11 colonies), and Aspergillus spp. (4 colonies). The three bacteria were shown to be lipolytically active, as evidenced by the formation of a clear zone in the NAL medium. Supplementation with oil palm frond extract significantly increased colony growth, with the highest yield at a concentration of 1% (>360 colonies/15 mL). ANOVA analysis showed differences in degradation effectiveness between colonies, with Aspergillus spp. exhibiting higher activity than other colonies. These findings confirm that the use of indigenous lipolytic bacteria in combination with oil palm frond extract can be a sustainable bioremediation strategy to reduce oil and fat content in LCPKS.
