Abstract

Critical thinking skills are important for students, but not all students possess strong critical thinking abilities. This study aims to develop a STEM-EDP-based Student Worksheet media to improve students' critical thinking skills in the topics of Ecology and Biodiversity. This research uses the ADDIE development model, developed by Robert Reiser and Michael Molenda, which consists of five stages: Analysis, Design, Development, Implementation, and Evaluation. The developed media was validated by experts in content and media, with the media expert validation result being 91% and the content expert validation result being 94%, both categorized as highly valid. Practicality testing was obtained from practicality questionnaires filled out by both teachers and students. The student practicality questionnaire resulted in 90.5%, categorized as very practical, and the teacher practicality test resulted in 90%, also categorized as very practical. The effectiveness of critical thinking skills was assessed through pretest and posttest results, using the N-Gain test, which resulted in a score of 0.7, categorized as high. Therefore, it can be concluded that the use of STEM-EDP-based Student Worksheets to improve students' critical thinking skills is effective and categorized as high.

Abstract

Insect pest attacks are one of the main obstacles in cultivating striped spinach (Amaranthus tricolor L.), because they reduce the quality and quantity of the harvest. Long-term use of synthetic pesticides has a negative impact on the environment and health. This study aims to test the effectiveness of the combination of soursop leaf extract (Annona muricata L.) and garlic (Allium sativum) as a botanical pesticide on the intensity of pest attacks. The study was conducted using a Randomized Block Design (RBD) with five concentration treatments (0%, 25%, 45%, 65%, and 85%) and five replications. Data were analyzed using ANOVA and BNT test at the 1% level. The results showed that the botanical extract treatment had a significant effect on reducing the intensity of pest attacks, with a concentration of 85% giving the most effective results (Fcount 236.05 > Ftable 4.77). The treatment of plant leaves showed lower damage than the control. This effectiveness is thought to be due to the content of active compounds, such as flavonoids, saponins, tannins, acetogenins, and alkaloids which are toxic to pests. In conclusion, soursop leaf and garlic extracts have the potential to be environmentally friendly botanical pesticides and can be used as an alternative to control striped spinach plant pests.

Abstract

Cayenne pepper (Capsicum frutescens L.) is a horticultural commodity with high economic value that is widely consumed by the Indonesian people, but is susceptible to various types of pests, especially in the generative phase. This study aims to identify the type and dominance of insect pests that attack cayenne pepper plants in the generative phase in the farmland of Thousand Pinang Waterfall, North Sempaja Village, Samarinda. The research methods used include direct observation and insect collection using several types of traps (insect nets, light traps, and pitfall traps). Identification is carried out down to the family level with the help of a keybook of determination and morphological character of insects. The results of the study showed the existence of several insect pest families such as Tephritidae (fruit flies), Thripidae (thrips), Aphididae (aphids), and Bemisiidae (whiteflies) that were dominant during the generative phase of the plant. So it can be concluded that cayenne pepper plants in the generative phase in the farmland of the Thousand Pinang Waterfall, Samarinda, are vulnerable to being attacked by various types of insect pests. This is important to support a more precise and effective pest control strategy in the critical phase of the growth of cayenne pepper plants.

Abstract

Microplastics are plastic particles smaller than 5 mm that originate from anthropogenic activities or environmental degradation. The estuarine waters of the Kenyamukan River in Sangatta, East Kutai Regency, are highly vulnerable to microplastic contamination due to intensive local activities such as fishing port operations, residential settlements, docks, and tourism sites. This study aimed to analyze the types and forms of microplastics found in several fish species inhabiting the estuarine area. The research employed a descriptive–analytical approach, with sampling conducted from March to May 2025. Fish organs analyzed included the gills and digestive system, which were extracted using NaCl solution, 10% KOH, and 30% H₂O₂, followed by observation under a stereo microscope. The results revealed the presence of microplastics in goatfish (Parupeneus indicus), spotted scat (Scatophagus sp.), rabbitfish (Siganus guttatus), and golden snapper (Lutjanus johnii). The identified microplastic types consisted of fibers (52%), fragments (27%), films (12%), and pellets (9%), with a total of 173 particles. The microplastic sizes ranged from 0.0012 mm to 0.1399 mm and exhibited various colors, including black, red, yellow, blue, green, transparent, orange, and pink. These findings indicate a high level of microplastic contamination in the Kenyamukan River estuary, posing potential threats to the aquatic ecosystem and the trophic food chain.

Abstract

This study aims to determine the effect of the implementation of the Project Based Learning (PjBL) learning model through a differentiation approach in improving creativity and learning outcomes of students in class XI of SMA Negeri 13 Samarinda. This research method uses a quantitative approach with a non-equivalent control group design. The population in this study was all class XI of SMA Negeri 13 Samarinda. Sampling used a purposive sampling technique. The sample in this study was class XI Moving Biology (XI-5 and XI-8) as an experimental class using the Project Based Learning (PjBL) learning model through a differentiation approach and XI-3 as a control class using a conventional learning model. Data were collected through tests in the form of essay questions and observation sheets. The data from the test questions and observation sheets were analyzed using an independent sample t-test and an N-gain test with the help of a data processing application. The statistical test results obtained from the independent sample t-test on creativity showed a significance value of 0.000 < 0.05, as well as the independent sample t-test on learning outcomes of 0.011 < 0.05, so H0 was rejected and Ha was accepted. It can be concluded that there is an influence of the application of the Project Based Learning (PjBL) learning model through a differentiation approach on creativity and learning outcomes of students in the experimental class. Furthermore, the N-gain test showed an increase in student learning outcomes after implementing the Project-Based Learning (PjBL) model through a differentiation approach, with an N-gain score of 0.91, in the high category. These research results indicate that implementing PjBL with a differentiation approach can be an effective alternative learning strategy for developing creativity and improving student learning outcomes in high school.
