Abstract

The diversity of macrozoobenthos plays an important role as an indicator of water quality. The purpose of this study was to describe the level of macrozoobenthos diversity in the waters of the Salusu River, Ogomatanang Village, Central Sulawesi as an indicator of pollution levels and to produce suitable learning media. The type of research is descriptive. The sampling technique used systematic random and used a subber net using a zig-zag transect line and analyzed the diversity index value. The results of the study found 9 species, divided into 8 families including Baetis sp., Alloperla sp., Parathelphusa convexa, Heptagenia solitaria, Orthetrum sabina, Nemoura sp., Tylomelania arabica, Tylomelania sp., Planaria sp. The diversity index (H') was consecutively at station III (upstream) which was 2.14 with a light level of pollution, the H 'index at station II (ecotone) was 1.91 and the H 'index at station I (downstream) was 1.28 with a moderate level of pollution. The research results obtained were used as validated learning media by a team of content experts by 80%, design 78.6%, media 80%, large group student group trials 85.5% and small group 89.0%. Learning media is very feasible to use with a result of 82.62%.

Abstract

This research aims to describe the level of diversity of insect species in various agricultural lands in Basidondo District, Tolitoli Regency, Central Sulawesi. The research was conducted in January-March 2025 using descriptive methods and quantitative approaches that aim to make a description or descriptive of a situation objectively using numbers. Insect sampling techniques were carried out with four types, namely pitfall trap, light trap, sweeping net, and hand collection. The insects obtained were then identified according to the taxonomic order with the help of insect determination key book, and analyzed using Shannon-Wiener diversity index (H'). The results showed that there were 24 types of insect families that were successfully identified. The value of the diversity index (H') was 3.13, which was classified as high diversity. These results indicate that agricultural land in Basidondo District has environmental conditions that support the diversity of insect communities, which can contribute to the stability of agricultural ecosystems. High diversity indicates a balance between insect pests and natural enemies, as well as the role of insects as pollinators and decomposers.

Abstract

This study aims to determine the effect of the STEM-based project-based learning (PjBL) model on students' creative thinking skills and learning motivation in biology at SMA Negeri 4 Palu. The study used a quantitative approach with a quasi-experimental design, the population in this study were all grade X students of SMA Negeri 4 Palu in the 2024/2025 academic year consisting of 12 study groups with a total of 400 students. The sample was determined through purposive sampling, consisting of an experimental class (n=33) receiving PjBL-STEM learning and a control class (n=33) with conventional learning. Data were collected through creative thinking skills tests and learning motivation observation sheets, then analyzed using normality tests, homogeneity tests, and independent samples t-tests. The results showed that the PjBL-STEM model had a significant effect on improving creative thinking skills (Sig. = 0.023 <0.05) and learning motivation (Sig. = 0.000 <0.05). This finding confirms that the integration of the STEM approach in PjBL not only strengthens the cognitive but also the affective aspects, so that it can be used as a strategic alternative in developing a biology curriculum to foster 21st-century competencies.

Abstract

This study aims to determine the density of macrozoobenthos in Toaya Village River Waters. This study uses a Quantitative Descriptive method with purposive sampling location determination consisting of 3 observation stations and sampling using the line Transect technique with a surber net sampling tool. Data analysis is done by calculating the density of samples that have been obtained in the field using the density formula. The results showed that (1) 5 types of macrozoobenthos were identified in the waters of Toaya Village River with the highest density at Station I (9.17 ind/m²) and the lowest at Station III (6.25 ind/m²). (2) These density differences reflect variations in environmental conditions, such as bottom substrate, water currents, pollution levels, and availability of organic matter. (3) Environmental conditions at station 1 are relatively more favorable for benthic organisms, while stations II and III reflect environmental pressures such as pollution or changes in habitat quality. Thus, macrozoobenthos acts as an effective bioindicator to assess water quality, so these results reflect the health level of the river ecosystem.

Abstract

This study aims to determine the level of difficulty of students in the subject of biological diversity biology in class X of MAS Al-Ikhlas Karya Mukti and describe the factors that cause students' learning difficulties in the subject of biological diversity biology. This study uses a descriptive method with a qualitative approach. The subjects of this study consisted of 40 students in class X. The types and sources of data used are primary, namely the results of interviews and questionnaires, and secondary data in the form of curriculum documents such as Learning Implementation Plans (RPP). Data analysis is carried out by data reduction techniques, data presentation, and drawing conclusions. The results of the study showed that (1) the average level of student learning difficulty in biodiversity materials reached 65%, which was included in the high category. (2) Internal factors such as the physical and psychological condition of students (70%) in the high category, interest and motivation in learning (75%) in the high category, and cognitive ability (63%) in the medium category. (3) External factors such as the learning environment at school (69%) in the high category, family support (63%) in the medium category, peer influence (61%) in the medium learning difficulty category, and limited learning resources (54%) in the medium category. Thus, it can be concluded that the level of student learning difficulties in biodiversity materials in class X of MAS Al-Ikhlas Karya Mukti shows that students experience high learning difficulties influenced by a combination of internal and external factors.

Abstract

This study aims is to identify the types of ectoparasites affecting Nile tilapia (Oreochromis niloticus). This research employed a survey method with purposive sampling technique. Fish samples were collected from two different locations, namely a tarpaulin pond and a soil pond in Binangga Village, Marawola District, Sigi Regency. Ten fish were sampled from each location and subsequently identified in the Biology Education Laboratory at Tadulako University. Observations were made on the external parts of the Nile tilapia, including the mucus, gills, fins, and tail. The parameter observed was the type of ectoparasite infecting the Nile tilapia. The results indicated the identification of five ectoparasite species: Dactylogyrus sp., Gyrodactylus sp., Attheyella sp., Cichlidogyrus sp., and Unitubulotestis sardae in 20 Nile tilapia samples. The highest prevalence of ectoparasites was found in the tarpaulin pond. However, both the tarpaulin and soil ponds shared one common ectoparasite species, Unitubulotestis sardae. The conclusion of this study is that Nile tilapia in both locations are infected by various ectoparasite species, with differences in prevalence between the tarpaulin and soil ponds.

Abstract

This study aimed to examine the relationship between learning styles, learning independence, and learning interest with biology learning outcomes among Grade X students at SMA Negeri 5 Palu. This research used a quantitative approach with a correlational method. A total of 176 students were selected using proportional random sampling. The instruments used were questionnaires and documentation of biology scores. Data analysis involved validity tests, reliability tests, normality tests, Pearson correlation, and multiple linear regression. The results showed a significant relationship between learning style (r = 0.668), learning independence (r = 0.747), and learning interest (r = 0.732) with biology learning outcomes (p < 0.05). Multiple regression analysis revealed that the three variables simultaneously influenced learning outcomes, with the regression equation Y = 9.771 + 0.502X₁ + 0.314X₂ + 0.357X₃ and R² = 0.656. This indicates that the three independent variables contribute 65.6% to the variance in biology learning outcomes. The findings highlight the importance of internal student characteristics in academic achievement, especially in biology learning.
