Abstract

Indonesia is a country rich in natural resources, including in the field of livestock, one of which is cattle. Cows have an important role as providers of meat needs for the community. However, cows are also at risk of being infected with worms that can reduce immunity, inhibit weight gain, and potentially cause death. The purpose of this study is to detect and identify nematode worm eggs in the feces of Balinese cows (Bos sondaicus) located in Mumbul Sari Village, North Lombok Regency. The sampling method in this study uses the purposive sampling method based on the maintenance system. Sampling of Balinese cow feces (Bos sondaicus) was taken in Mumbul Sari Village, North Lombok Regency, by taking fresh cow feces, then taken to the Parasitology Laboratory, Faculty of Veterinary Medicine, Mandalika Education University, to be examined using the saturated sugar flotation method, then observed under a microscope with a magnification of 100 times. The results of the study showed positive examination, namely the presence of Trichostrongylus sp; Toxocara vitulorum sp; Oesophagostomum sp; and Haemonchus contortus sp; on the feces of Balinese cattle from Mumbul Sari Hamlet, Bagek Nunggal, Pawang Kunyit I, Pawang Kunyit II, and Munder Hamlet.

Abstract

Microbiological contamination is one of the factors that affect food safety, especially in wet noodles which have a high moisture content so they are easily damaged. This study aims to determine the number of Total Plate Numbers (ALT) and identify the presence of Escherichia coli in wet noodles sold at Segiri Market, Samarinda City. The research was carried out using a descriptive analytical method through laboratory testing of five wet noodle samples taken by purposive sampling. ALT testing uses the pour plate method on Plate Count Agar (PCA) media, while Escherichia coli testing is carried out by the Most Probable Number (MPN) method followed by confirmation on Eosin Methylene Blue Agar (EMBA) media. The results of the ALT test showed that two samples met the maximum limit of ALT according to SNI 2987:2015 (≤1.0 × 106 colonies/g), while three samples exceeded the threshold. The MPN test showed that four samples were below the maximum limit according to SNI 2987:2015 (≤10 APM/g) and one sample exceeded the threshold. The EMBA confirmation showed two positive samples of Escherichia coli. These results confirm the importance of applying hygienic practices in the processing, storage, and packaging to reduce the risk of microbiological contamination.

Abstract

Problem-solving skills are an essential aspect that learners must have to deal with complex problems in real life. However, various studies show that students in Indonesia still have a low level of ability in this aspect. This study aims to measure the improvement of problem-solving skills through the application of Problem-Based Learning (PBL) based on Socio-Scientific Issues (SSI) on the topic of environmental change. This study uses a pre-experimental method with a one-group pretest-posttest design involving 34 students of class XI MIPA 1 at SMAN 1 Banjarmasin for the 2025/2026 school year. Sample selection was carried out by total sampling technique. The post-test results showed that the students' problem-solving skills were in the good category, with an average of 83.15%. MANOVA's analysis produced a significance value of 0.000 (< 0.05) which confirms that SSI-based PBL has a significant influence on improving problem-solving skills while fostering students' awareness of environmental conservation efforts. The findings of this research are expected to be a practical guide for educators in designing learning that is able to foster problem-solving skills as one of the competencies of the 21st century.

Abstract

The biology learning process utilizes a variety of teaching materials, including package books and Student Worksheets (LKPD). However, the LKPD used by teachers is still limited to practicum activities and has not met the components of the preparation of the LKPD optimally. To overcome this, LKPD based on Problem Based Learning (PBL) was developed which has the advantage of improving students' ability to solve problems contextually. This research aims to produce PBL-based LKPD on ecosystem materials that are valid for students in phase E of high school/ma. Development is carried out using a 4D model which includes the stages of defining, design, develop, and disseminate. The research was limited to the development stage with a validity test through filling out a questionnaire by three expert lecturers. The validation results showed that LKPD was in the very valid category with a score of 86.99%. Thus, the PBL-based LKPD developed is declared suitable for use as teaching materials in biology learning.

Abstract

In the learning process, students have used various teaching materials, such as modules, printed books, and Student Worksheets (LKPD). In addition, the learning process is also supported by the application of the problem-based learning model. One of the materials studied in grade XII of high school is biotechnology innovation. In the material, teachers use a problem-based learning model. This research aims to produce a LKPD based on problem based learning on valid biotechnology innovation materials in phase F of high school/MA. This type of research is a development research using a 4D model which includes four stages, namely define, design, develop, and disseminate. However, in this study, the disseminate stage was not carried out. The research instrument is in the form of a validation sheet used to test the validity carried out by three validators. The results of the study showed that the validity test by biology lecturers and teachers obtained an average score of 84.84% which is included in the very valid category. Thus, it can be concluded that the LKPD based on problem-based learning on the biotechnology innovation material phase F SMA/MA developed, is feasible to use.

Abstract

The effect of light on stomata has been extensively studied, but studies that specifically observed the effect of light intensity on the size and number of stomata in monocot plants at the Sempaja Arboretum, Samarinda, are still very limited, including monocot plants, and have the potential to be a contextual learning resource for biology education in schools. The purpose of this study is to determine the effect of light intensity on the number and size of stomata in monocot plants in the Sempaja Arboretum. This research was carried out from February to May. This study used a Non-Factorial Group Random Design, with 3 different light intensities (morning, noon, and evening). Based on the results of statistical tests (ANOVA and Duncan's follow-up tests), not all species show statistically significant differences in size and number between times (morning, noon, evening). Some species such as Sri Rejeki (Aglonema sp) and Turmeric (Curcuma longa) show statistically insignificant changes. In other species such as Virginia Flower (Commelina virginica), Palm (Arenga pinnata), and Golden Ivory Betel (Epipremnum aureum), the difference in stomata size between times is more pronounced and significant.

Abstract

Technological progress requires innovation in all components of education, one of which is by integrating the Sustainable Development Goals (SDGs) into learning through practicum-based breathing system e-modules. This study aims to analyze the influence of practicum-based respiratory system e-modules on the learning outcomes of grade XI students of SMA Negeri 13 Samarinda in the cognitive, affective, and psychomotor domains in supporting the achievement of SDGs 3. The research method used a quasi experiment type of non-equivalent control group with two subjects (30 students each), one class as an experiment and one class as a control. Instruments include cognitive tests (pretest–posttest) as well as affective and psychomotor observations. Cognitive data analysis used an independent t-test, while affective and psychomotor were analyzed descriptively and converted to qualitative categories. The results showed significant differences in cognitive learning outcomes (sig. 0.000 < 0.05). The affective learning outcomes of both classes were in the good category, with the experimental class showing a higher score of 78.89, while the control class was 74.11. The psychomotor learning outcomes of the experimental class were in the skilled category with an average of 75.09, while the control class was quite skilled with an average of 69.17. Therefore, it is concluded that practicum-based e-modules are effective in improving learning outcomes while fostering health and environmental awareness in accordance with SDGs 3.
