Abstract

This study aims to identify and describe the diversity of medicinal plants utilized by the community of Tindaki Village, South Parigi District, and to document their scientific names, morphological characteristics, plant parts used, and methods of preparation. The research employed a descriptive design with a qualitative approach using exploratory techniques. Data were collected through direct field observations conducted in six hamlets, structured interviews with ten informants consisting of five key informants and five supporting informants, and field documentation. Species identification was carried out through detailed observations of morphological characteristics, including roots, stems, leaves, flowers, and fruits. The identification results were subsequently verified using relevant scientific literature to ensure taxonomic accuracy. The findings revealed a total of 34 medicinal plant species belonging to 23 families and 18 orders. The plant parts most commonly utilized by the community were leaves and rhizomes, followed by fruits, roots, stems, and sap. These plants are traditionally used to treat various health conditions, including fever, cough, diarrhea, diabetes, hypertension, kidney stones, digestive disorders, and skin diseases. In conclusion, the results indicate that Tindaki Village possesses a high diversity of medicinal plants that continue to be actively utilized by the local community. Therefore, sustained conservation and systematic documentation efforts are essential to preserve this valuable ethnobotanical knowledge for future generations.

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.

Abstract

This study aims to identify the impact of online game addiction on students’ academic behavior in Biology learning at SMA Negeri 5 Palu. A descriptive qualitative method was employed. The research subjects consisted of four Grade X Merdeka 2 students, selected purposively, and a Biology teacher. Data were collected through interviews and documentation. This study addresses a gap in previous literature by examining students’ subjective experiences regarding the effects of online game addiction on academic behavior in Biology classes at SMA Negeri 5 Palu. The findings indicate that online game addiction affects three aspects of students’ academic behavior: decreased classroom participation, lack of discipline in submitting assignments, and potential disruption of academic achievement. Among these aspects, students’ lack of discipline in completing assignments emerged as the most prominent and evident impact. This was supported by the consistency of interview responses from all informants, the normalization of rule violations, and confirmation from the Biology teacher that, without reminders, assignment submission could be delayed for up to one week. It can be concluded that interventions aimed at improving students’ discipline, time management, and daily limits on online gaming are needed through collaboration among schools, teachers, and parents.

Abstract

This study aimed to analyze the effect of moringa leaf flour addition at concentrations of 0%, 5%, 10%, and 15% on the sensory quality of crackers and to identify the most acceptable formulation based on consumer preference. The study employed a Completely Randomized Design (CRD) with three replications. Organoleptic evaluation was conducted with 30 untrained panelists using a 5-point hedonic scale to assess color, aroma, taste, and texture. The data were analyzed using one-way analysis of variance (ANOVA), followed by Tukey’s HSD test at a significance level of α = 0.05. The results showed that moringa leaf flour addition had a significant effect on all organoleptic attributes (p < 0.05). The formulation containing 10% moringa leaf flour showed the most balanced sensory profile, with mean hedonic scores of 3.60 for aroma, 3.47 for texture, 3.10 for taste, and 3.03 for color. These scores ranged from neutral to approaching like, indicating that the 10% formulation was relatively the most acceptable formulation compared with the other treatments.

Abstract

This study aimed to analyze the effect of implementing the Problem-Based Learning (PBL) model on eighth-grade students’ science learning outcomes. This study employed a quantitative quasi-experimental approach with a nonequivalent control group design. The sample consisted of 53 eighth-grade students who were assigned to an experimental class and a control class. The experimental class was taught using the PBL model, whereas the control class received conventional instruction. Data were collected using a multiple-choice test administered before and after the treatment as a pretest and posttest. The test was designed to measure students’ cognitive learning outcomes in science. The data were analyzed using an independent samples t-test after the initial abilities of the two groups were examined. The results indicated that the two groups had relatively equivalent initial abilities before the intervention. After the treatment, the experimental class achieved a higher posttest mean score than the control class, and the difference between the groups was statistically significant. These findings suggest that PBL is more effective than conventional instruction in improving students’ science learning outcomes.
