Abstract

This study aims to analyze the waste disposal behavior of visitors to Loang Baloq Beach, Mataram City, and the factors influencing it. This study used a quantitative descriptive approach involving 35 respondents selected through accidental sampling in December 2025. Data were collected through a closed-ended questionnaire using a Likert scale, field observations, and documentation, then analyzed descriptively through frequency calculations, percentages, and average values. The results showed that most respondents had a very good level of hygiene knowledge, but proactive behavior in maintaining cleanliness was still low. Basic behavior of disposing of waste in the proper place was high, while advanced behaviors such as picking up trash, bringing home recyclable waste, and reprimanding violators were still rare. This condition was supported by limited trash bin facilities, a lack of warning signs, and a lack of supervision at the study site. These findings indicate a gap between knowledge and practice of hygiene behavior in the Loang Baloq Beach area.

Abstract

The micro-scale tofu-tempeh industry in Abian Tubuh Baru Village has a strategic economic role, but its production activities produce liquid waste with a high organic load that risks degrading the aquatic ecosystem. This study aims to analyze in depth the behavior of micro-business actors in liquid waste management, as well as the community's social response to waste disposal in the Abian Tubuh Baru Village Watershed. The research method used is descriptive qualitative with a case study approach. Data were collected through field observations and in-depth interviews with business actors and the surrounding community who were selected purposively until data saturation was achieved. Data analysis was carried out thematically using the Miles & Huberman interactive model. The results showed that liquid waste is still discharged directly into water bodies without treatment due to the persistence of habitual factors, limited environmental literacy, and the absence of waste processing infrastructure facilities. This condition causes a significant decline in river water quality, characterized by changes in physical parameters (color and turbidity), and the emergence of a pungent odor due to organic decomposition. The community shows a tendency to act passively through environmental normalization by choosing to stop using river water rather than carrying out social control. These findings imply the urgency of community-based environmental awareness-building interventions for sustainable river pollution mitigation.

Abstract

Single-use plastic remains a major pollution problem in the campus environment. This study aims to analyze the single-use plastic consumption behavior of students in the Faculty of Mathematics and Natural Sciences (FMIPA) at the University of Mataram based on the Theory of Planned Behavior (TPB), including attitudes, subjective norms, perceived behavioral control, intentions, and actual behavior. This study used a descriptive quantitative approach, with 94 students selected through stratified random sampling from six study programs as respondents. Data were collected using a 1–5 Likert scale questionnaire and analyzed descriptively. The results showed that all TPB constructs tended to be in the moderate category, indicating that environmental awareness has been established but has not yet developed into consistent behavioral habits. A similar trend was seen across attitudes, subjective norms, perceived behavioral control, and actual behavior. The Environmental Science Study Program consistently scored higher than other study programs, indicating that an ecologically based academic culture plays a crucial role in establishing stronger social norms, thus enabling environmentally conscious behavior to be realized.

Abstract

The use of plants in the Mecaru ritual at Singosari Temple represents an important aspect of local wisdom that is at risk of decline due to limited scientific documentation and the influence of modernization. This study aims to document and examine local community knowledge regarding the use of plants in the Mecaru ritual at Singosari Temple, Malang Regency. The research employed a descriptive qualitative approach, with data collected through observation, semi-structured interviews, and documentation. Informants were selected purposively and expanded using the snowball sampling technique. The results revealed that 11 plant species belonging to 9 families were utilized, with various growth forms including trees, herbs, shrubs, and bushes. The most commonly used plant parts were flowers, followed by leaves and fruits, with most of them used in fresh condition. These plants hold philosophical meanings related to spiritual values, symbols of purity, and expressions of gratitude in community life. In general, the conservation status of these plants has not been widely identified; however, the practice of utilizing local plants reflects efforts toward the sustainable use of resources. These findings highlight the important role of the Mecaru ritual in preserving local wisdom, strengthening ethnobotanical studies, and supporting cultural and environmental sustainability.

Abstract

Changes in community consumption patterns that tend to reduce the use of local vegetables, so that ethnobotanical studies are needed to document and analyze their potential as a sustainable food source. This study aims to identify the diversity and utilization of local vegetables, as well as analyze the ethnobotanical index based on the knowledge of the Ngabab Village community. This study uses a mixed methods approach with an exploratory sequential design. Data were collected through interviews, observations, documentation, and surveys. The determination of informants and respondents was done purposively. Data analysis was carried out qualitatively using the Miles and Huberman model, and quantitatively using the ethnobotanical index. The results showed that there were 11 local vegetable species from 5 families utilized by the community. The Informant Consensus Factor (ICF) value was 0.98, the RFC value showed the highest result of 0.93 in Brassica oleracea (cabbage) which indicates that this species is the vegetable most utilized by the community. In addition, the highest SUV value was also found in Brassica oleracea at 2.12 which indicates the most dominant level of use compared to other species. The Brassicaceae family had the highest FUV value of 1.41, and the most widely utilized part (PPUV) was the fruit (33.03%). The conclusion of this study is that local vegetables play a vital role in the community's food system and have the potential to support food security and the sustainable preservation of local knowledge.

Abstract

This study aims to develop a Problem-Based Learning (PBL)-based biology e-module with a local theme from Tuban Regency, focusing on environmental issues. The study used a Research and Development (R&D) model with ADDIE stages limited to analysis, design, and development. The data collection instrument was a validation sheet that assessed the feasibility of the material, systematics, language, and media design and presentation. The results showed that the PBL-based biology e-module with a local theme from Tuban met the criteria of highly valid, with an average score of 81.75% from biology learning media expert validators and 97.5% from science learning material expert validators (biology). Based on these results, the developed e-module is suitable as a supporting teaching material in biology lessons for seventh-grade junior high school students on environmental issues with a local theme.

Abstract

This study aims to analyze the effect of the shared integrated learning model on student learning outcomes and motivation in the circulatory system topic in grade XI of SMAN 4 Samarinda. This study used a quasi-experimental method with a non-equivalent control group design and purposive sampling technique. The research sample consisted of 25 students in the experimental class and 25 students in the control class. The research instruments were a learning outcome test and a learning motivation questionnaire. Data analysis was conducted using the N-gain test and independent sample t-test at a significance level of α = 0.05. The results showed that the N-gain of learning outcomes in the experimental class was 0.61 (medium category) higher than the control class at 0.31 (low category). The N-gain of learning motivation in the experimental class was 0.20 (low category) also higher than the control class at 0.04 (very low category). The results of the hypothesis test showed a significance value <0.05, so the shared integrated learning model has a significant effect on student learning outcomes and motivation in the circulatory system topic.
