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.

Abstract

This study aimed to analyze the macronutrient composition of seaweed noodles (Eucheuma cottonii) formulated with different levels of seaweed flour substitution and to develop the research findings into a poster-based learning medium. A laboratory experiment was conducted using a one-factor completely randomized design (CRD) comprising four treatments: P0 (100% wheat flour:0% seaweed flour), P1 (90%:10%), P2 (80%:20%), and P3 (70%:30%), with three replicates per treatment. Carbohydrate, protein, and fat contents were determined using the Anthrone, Biuret, and Soxhlet methods, respectively. Macronutrient data were analyzed using one-way analysis of variance (ANOVA) at a 5% significance level, followed by the least significant difference (LSD) test. Seaweed flour substitution significantly affected the carbohydrate, protein, and fat contents of the noodles. The carbohydrate contents of P0, P1, P2, and P3 were 56.278%, 71.631%, 68.402%, and 65.490%, respectively. The corresponding protein contents were 4.355%, 7.441%, 6.458%, and 5.337%, while the fat contents were 1.117%, 1.262%, 1.097%, and 0.896%, respectively. Among the tested formulations, P1 exhibited the highest carbohydrate and protein contents. The poster-based learning medium received feasibility scores of 85% from the content expert, 85% from the design expert, 85% from the media expert, and 90% from the student participants, yielding an overall mean score of 86.25% and placing it in the highly feasible category. These findings demonstrate that E. cottonii substitution affects the macronutrient profile of noodles and that the resulting research findings can be effectively developed into a feasible research-based learning medium.
