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 occurrence and abundance of microplastics in the digestive tract of eels (Anguilla sp.) from Lake Poso and to implement the findings as an educational poster-based learning medium. A quantitative descriptive method was employed using six eel samples collected from the Pamona area. Microplastic analysis was conducted through organic matter digestion using 10% KOH solution, filtration with Whatman No. 42 filter paper, and microscopic particle identification. The results showed that all samples (100%) were contaminated with microplastics, with a total of 221 particles and an average abundance of 36.8 particles per individual. The identified microplastic types consisted of fibers (56.56%), fragments (23.53%), and films (19.91%), while pellets were not detected. The dominance of fibers suggests that the main sources of contamination were likely domestic and fishing activities around Lake Poso. The research findings were subsequently developed into an educational poster, which obtained an average feasibility score of 84% and was categorized as highly feasible. These findings contribute to scientific knowledge on microplastic contamination in freshwater eels and demonstrate the potential of local research findings to serve as contextual learning resources for improving students’ environmental literacy and awareness.

Abstract

Microplastic pollution is an emerging environmental concern because these particles can accumulate in aquatic ecosystems but are difficult to detect visually. This study aimed to identify the morphological types and determine the density of microplastics in sediments from Lake Poso, Central Sulawesi, Indonesia, and to develop an educational poster based on the findings. A quantitative descriptive approach was applied. Sediment samples were collected from three categories of sites: an area with minimal human activity, a tourism area, and a residential area. Two sampling points were established at each site, yielding six sediment samples. At each sampling point, 200 mL of sediment was collected using the hand-collection method and analyzed at the Biology Laboratory, Faculty of Teacher Training and Education, Tadulako University. Organic matter was digested using a 10% KOH solution, after which the samples were filtered and examined microscopically. Suspected microplastic particles were classified as fibers, fragments, films, or pellets. Microplastics were detected in all sediment samples, although their density varied among sites. Fragments were the most abundant type, followed by fibers, films, and pellets. Microplastic densities were 170 particles/100 g of dry sediment at the site with minimal human activity, 281 particles/100 g at the tourism site, and 218.5 particles/100 g at the residential site. The educational poster developed from these findings was evaluated by content, design, and media experts, as well as student users, and was categorized as highly suitable for educational use. These findings indicate that Lake Poso sediments are contaminated with microplastics, potentially associated with tourism, fisheries, residential activities, and other anthropogenic inputs. Improved waste management and environmental monitoring are therefore needed to reduce microplastic contamination in the lake.

Abstract

This study aimed to identify the morphological types of microplastics present in the digestive tracts of squid (Loligo sp.) sold at a traditional market in Palu City. A descriptive approach combining quantitative and qualitative analyses was employed. A total of 10 fresh squid specimens were randomly selected from a single vendor at Lasowani Traditional Market. The digestive tracts were isolated, digested using 10% potassium hydroxide (KOH), and incubated at 40°C for 96 h. The recovered particles were subsequently classified and counted, and microplastic abundance was calculated. Three morphological types of microplastics—fibers, films, and fragments—were detected in the digestive tracts of the 10 squid specimens. A total of 948 particles were recorded, corresponding to a mean abundance of 94.8 particles per individual. Films were the most prevalent type, accounting for 48.4% of the total particles, followed by fragments at 26.7% and fibers at 24.9%. These findings indicate that film-type microplastics were dominant in the digestive tracts of the examined squid. Based on the research findings, an educational poster was also developed and subjected to expert validation. The poster achieved a feasibility score of 82.23%, indicating that it was highly suitable, based on the validation results, for use as a learning resource in biology education.

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.

Abstract

This study aimed to analyze the effect of collaborative project-based learning (PjBL) on students’ communication skills at SMP Negeri 4 Palu. A quasi-experimental nonequivalent control group design was employed, involving 22 students in the experimental group and 24 students in the control group selected through cluster random sampling. The intervention was implemented through a contextual project, the Eco-Soil Poster Campaign, which involved creating a digital poster campaign promoting soil health conservation within the school environment. Data were collected using a posttest communication skills questionnaire, while a cognitive pretest was administered to verify the initial equivalence of the two groups. The instrument was validated using Aiken’s V and Cronbach’s Alpha. The results revealed a significant difference between the two groups (p = 0.018 < 0.05), with the experimental group achieving a higher mean score (75.64%, categorized as Good) than the control group (69.83%, categorized as Fair), accompanied by a moderate effect size (Cohen’s d = 0.724). These findings indicate that collaborative PjBL significantly improves students’ communication skills and can be recommended as an effective instructional strategy for junior high school biology learning.
