Abstract

Purpose of the study: Rattan, a valuable resource for both industry and local food, is evaluated for its nutritional content in this study. The research explores its potential as a learning resource based on local wisdom in Sibado Village, Sirenja District, aiming to raise awareness and promote sustainable use within the community. Methodology: A quantitative descriptive research approach was used, involving proximate analysis to measure (Soxhlet method), protein (spectrophotometric method), water (thermogravimetric method), ash (dryashing method), and carbohydrates (proximate method) of rattan shoots. Data were collected from Sibado Village and analyzed in the Chemistry Laboratory of Tadulako University, Palu. An e-pocket book was developed as a learning resource. Main Findings: The results of the study obtained an average fat content of 0.332%, protein content of 2.110% and carbohydrate content of 6.082%. The results of the study were integrated as a learning resource in the form of a local wisdom-based pocket book that had been validated by content experts, design experts, media experts and students with an average value of 81.7%, meaning it is very suitable for use as a learning resource. Novelty/Originality of this study: This study is the first to combine nutritional analysis of Daemonorops robusta with the development of a local wisdom-based educational tool, bridging scientific data and pedagogy to enhance biodiversity awareness, cultural relevance, and contextualized learning in formal education.

Abstract

This study aimed to assess the density of Polymesoda sp. in the mangrove ecosystem of Pinotu Village, Toribulu District, Parigi Moutong Regency, an area experiencing habitat pressure due to environmental change. A quantitative descriptive approach was applied using purposive sampling across three stations: Station 1 behind the residential area, Station 2 in the central mangrove zone, and Station 3 near shrimp ponds. Sampling was conducted at low tide using a line transect method with zigzag plots. Each station consisted of three 25 m transects spaced 10 m apart, with five 1 m² plots established along each transect, yielding a total of 45 observation plots. Environmental parameters measured included temperature, salinity, and pH. The highest density of Polymesoda sp. was recorded at Station 2 (2.93 ind/m²), followed by Station 1 (1.87 ind/m²), whereas the lowest density was observed at Station 3 (0.87 ind/m²). Differences in density were associated with habitat variation, particularly mangrove vegetation density, substrate characteristics, and environmental physical and chemical conditions. These findings indicate that more stable and better-preserved mangrove habitats support higher densities of Polymesoda sp., highlighting the importance of habitat quality in sustaining its population.

Abstract

This study aimed to analyze the community structure of fiddler crabs (Uca) in the mangrove ecosystem of Lalombi Village, South Banawa District, Donggala Regency, and to utilize the research findings as instructional media in the form of a flipbook. This ecological study employed a quantitative descriptive approach based on community structure analysis, with samples collected using purposive sampling. The parameters analyzed included species composition, density, the Shannon–Wiener diversity index, the Simpson dominance index, and the evenness index, along with environmental variables such as temperature, salinity, pH, and substrate type. The results showed that the fiddler crab community in the mangrove ecosystem of Lalombi Village consisted of five species, namely Uca annulipes, Uca lactea, Uca forcipata, Uca tetragonon, and Uca dussumieri. Abundance varied across sampling stations, and the overall diversity level was classified as low to moderate. The occurrence frequency of these five fiddler crab species was very low. The recorded densities were 6 ind/m² for Uca annulipes, 3 ind/m² for Uca lactea, 5 ind/m² for Uca forcipata, 7 ind/m² for Uca tetragonon, and 3 ind/m² for Uca dussumieri, with a low dominance index. The environmental physicochemical conditions recorded for fiddler crab habitat were a temperature of 30°C, water pH of 8.25, salinity of 31, and a muddy substrate type. Overall, the fiddler crab community structure in the mangrove ecosystem of Lalombi Village was relatively stable, characterized by low to moderate diversity, low dominance, and a clumped distribution pattern influenced by substrate conditions and mangrove density.

Abstract

This study aimed to examine the effect of nutrition education on students’ breakfast habits and learning outcomes at SMA Negeri 1 Sausu, while also highlighting its role in promoting healthier breakfast behaviors among students. The study employed a quantitative approach using a one-group pretest-posttest design. The participants were 23 tenth-grade students selected through total sampling. Data were collected using questionnaires to assess students’ breakfast habits before and after the intervention, as well as documentation of students’ learning outcomes. Data were analyzed using descriptive quantitative analysis through mean scores, score improvement, and N-gain values. The results showed that the mean breakfast habit score increased from 40.09 in the pretest to 48.43 in the posttest, with an N-gain of 0.14, which was categorized as low. In addition, the mean learning outcome score increased from 77.30 before the intervention to 80.17 after the intervention, with an N-gain of 0.13, also categorized as low. These findings indicate that nutrition education contributed positively to improvements in students’ breakfast habits and learning outcomes, although the level of effectiveness remained low. Therefore, nutrition education has the potential to serve as a promotive and preventive strategy for fostering healthy breakfast behaviors and supporting academic improvement, provided that it is implemented continuously and supported by both the family and the school environment.
