Abstract

Genetic concepts are complex and often lead to student misconceptions due to difficult textbooks and ineffective teaching strategies. Widespread misunderstandings highlight the need for effective instructional techniques to enhance comprehension. This study examine the teaching techniques employed by Biology teachers in 20 high schools in Pontianak City to evaluate their implementation, strengths, and limitations in genetics instruction. This study used a qualitative survey approach to examine teaching techniques for genes, DNA, and chromosomes in 12th-grade classes across 20 high schools in Pontianak City. Data were collected through validated questionnaires and observation sheets, focusing on learning activities, instructional approaches, and challenges faced by teachers. Responses were summarized in tables, analyzed descriptively, and presented to highlight technique variations, selection criteria, and implementation. A total of 20 teaching techniques were identified, with most schools using a combination of 2 to 5 methods, while only three schools applied a single technique, and discussion was the most frequently integrated approach. Teaching techniques for Genes, DNA, and Chromosomes in Pontianak high schools vary, with most teachers combining multiple methods to enhance understanding, interaction, and engagement. The selection and combination of techniques are influenced by student needs, classroom conditions, and learning objectives, highlighting the importance of a balanced approach between student-centered, teacher-led, and objective-driven strategies.

Abstract

The implementation of the Adiwiyata program is expected to enhance students' awareness and understanding of environmental issues, fostering a strong sense of ecoliteracy. However, based on the facts in the field, the existence of the Adiwiyata program has not been able to guarantee an increase in environmental awareness among students. This study aims to analyze the implementation of the Adiwiyata program in fostering and developing student ecoliteracy. This study is a descriptive research employing quantitative methods, aimed at objectively describing and analyzing existing phenomena or conditions related to the implementation of the Adiwiyata program and its impact on student ecoliteracy. In collecting data, researchers used a questionnaire completed directly by junior high school students participating in the Adiwiyata program, involving 101 students from six schools. The data collected from respondents were analyzed using quantitative descriptive analysis techniques. This study shows that students in Adiwiyata schools show a level of ecoliteracy in the sufficient category. This is due to various factors, one of which is that the implementation of the Adiwiyata program in junior high schools in Padang City is still relatively voluntary and independent. Support from all stakeholders, including the education office and local communities, is necessary to ensure that the Adiwiyata program is not only symbolic but also truly creates a sustainable ecoliteracy transformation.

Abstract

Analytical skills are one of the essential skills that high school students must possess and are listed in the curriculum. Analytical skills are included in category C4 in Bloom's taxonomy. However, many students still lack this ability. This is influenced by several factors, one of which is the type of learning media. This study aims to evaluate the effectiveness of the Cells at Work animation as a learning medium for biology, with a focus on the material related to the circulatory system. The method used is a pre-experimental design with a one-group pre-test-post-test model, conducted on class XI- MIPA 5 students at SMA Pasundan 2, Bandung. The results of the study showed that this animation media makes it easier for students to understand the material due to its attractive visual and audio displays. This can be seen from the increase in the average student score, namely from 56 at the pre-test to 83 at the post-test, with the percentage of mastery of all indicators reaching 83%. Thus, the Cells at Work animation is effective for use as a learning medium in biology, especially for material related to the circulatory system. This study provides empirical evidence that animated media with contextual content, such as Cells at Work, can significantly enhance analytical thinking skills in science learning, particularly for complex topics like the circulatory system.

Abstract

Microgreens are a key concept in urban farming due to their ability to be grown easily, affordably, and efficiently in limited urban space. This study aims to determine the growth and yield of microgreens from the Brassica sp. family, which is cultivated under limited lighting conditions. This research was conducted from February to March 2025 at the laboratory of the Faculty of Agriculture, Singaperbangsa University, Karawang. This study employed an experimental method using a Split-Plot design within a Group Randomized Design framework, consisting of a main plot and a subplot. The main consisted of six levels of limited light exposure: indoor control, outdoor control, lighting at 60%, lighting at 50%, lighting at 40%, and lighting at 30%. The subplots were divided into three plant types: cauliflower, radish, and broccoli. Each treatment was repeated twice, resulting in a total of 36 experimental units. The effects of the treatment were analyzed using a variety of F-tests at the 5% significance level. When a significant interaction was detected, further analysis was conducted using the DMRT (Duncan's Multiple Range Test). The experimental results indicated a significant interaction between limited light exposure and plant type on the observed parameters of growth uniformity and plant height at 7 days after planting (DAP). The combination of lighting at 50% with broccoli plants provides the highest growth coherence value of 88%. In contrast, the highest value at 7 days after planting, measuring 6.55 cm, was observed in the lighting at 30% combined with broccoli plants.

Abstract

Elevated blood glucose levels, known as Hyperglycemia, are a key feature of diabetes mellitus (DM), which remains a primary global health challenge. The rising prevalence of type 2 diabetes and the side effects of synthetic drugs have led to interest in natural alternatives. Bay leaves (Syzygium polyanthum), commonly used in Indonesian cuisine, contain bioactive compounds such as flavonoids, tannins, and terpenoids that may have antidiabetic properties. This study examined the effect of bay leaves preparations—decoction, tea, and filtrate—on blood glucose levels in hyperglycemic white rats and identified the most effective form. A proper experimental design involved 25 male rats, divided into five groups: a negative control, a positive control (alloxan only), and three treatment groups (decoction, tea, and filtrate). Hyperglycemia was induced using alloxan (150 mg/kg BW), and treatments were given orally twice daily for 30 days. Blood glucose levels were measured before and after treatment using a GlucoDr glucometer. Data were analyzed using one-way ANOVA and the LSD test (α = 0.05). Significant differences were observed among groups (Fhit = 16.61 > Ftab = 2.87). The decoction group had the most considerable glucose reduction (112.4 mg/dL), closely followed by the negative control (118 mg/dL), while the tea and filtrate groups showed lesser effects. Decoction proved most effective, likely due to better compound extraction. These findings highlight the potential of bay leaves decoction as a natural remedy for hyperglycemia, warranting further clinical research.

Abstract

Applying probiotics to the recirculation system can support successful catfish production. This study aims to apply an aquaponic cultivation method that combines catfish (Clarias sp.) and water spinach cultivation by adding Probio-7 probiotics as a digestive aid to accelerate growth and improve the survival rate of catfish. This study was carried out at UPR Doa Mandeh, using the experimental design that compared the effects of probiotic application on aquaculture performance, and aimed to evaluate the effectiveness of weekly probiotics administration in a controlled aquaculture setting. Probiotics are introduced at the start of the maintenance period and reapplied weekly, following a 30% water loss, and promptly replaced with clean water. This routine was designed to maintain optimal water quality and microbial balance, supporting healthier aquatic life. The consistent probiotic treatment, aligned with systematic water management, highlights a practical approach to improving fish health and growth performance in sustainable aquaculture practices. The treatments used were without probiotics (P0) and the addition of probiotics at a rate of 0.25 mL L- 1 water (P1). The results of the research activities in P1 showed absolute length growth of 16.71 cm, absolute weight of 16.44 g, feed efficiency of 84.3%, and fish survival rate of 79%. These values were higher than those in P0, which had an absolute length growth of 5 cm, absolute weight of 11.94 g, feed efficiency of 84.3%, and fish survival rate of 77%. Water quality during the study remained within the optimal range, supporting the growth and survival of catfish.

Abstract

This research focuses on the development of an e-module integrating the Socio-Scientific Issues (SSI) approach in teaching human reproductive system material to enhance critical thinking skills among 11th-grade students at SMAS Cerdas Murni. The study was motivated by the low level of students' critical thinking skills, the predominance of conventional teacher-centered methods, and the lack of interactive and contextual learning materials that can connect concepts to real-life issues. The research employed a Research and Development (R&D) design with the 4D model (Define, Design, Develop, and Disseminate). The scope was limited to the development stage due to time and budget constraints. The developed SSI-based e-module was validated by subject matter experts, yielding a feasibility score of 96.43%, and by media experts, yielding a score of 95.31%, both categorized as “highly feasible.” Practicality testing by biology teachers and students resulted in percentages of 96.67% and 95.33%, respectively, indicating the e-module is “very practical” for classroom use. Effectiveness was measured through an N-Gain analysis, producing a score of 0.80, which falls into the “high” category and demonstrates a significant improvement in students’ critical thinking skills. These findings indicate that the SSI-based e-module is feasible, practical, and effective in supporting the development of critical thinking skills, providing an innovative and engaging alternative to conventional biology teaching on the human reproductive system. The module has potential for broader implementation in senior high school biology learning.

Abstract

The habit of people who live in cities and villages likes instant smells, for example, consuming soft drinks. One of the soft drinks popular in the community is carbonated drinks. This study aims to determine the effect of carbonated drinks on blood glucose levels of mice. This study used 21 male mice Balb C strain aged 2-3 months, which was divided into 3 groups, namely K1 given aquadest dose of 0.86 ml / 20 g body weight. K2 is given a carbonated drink dose of 0.43 ml / 20 g body weight. K3 was given a carbonated drink dose of 0.86 ml / 20 g body weight. All treatments were given for 14 days. The average increase in blood glucose levels of mice in KI, K2, and K3 were 16.71 mg / dl, 11.63 mg / dl, and 67.59, respectively (P<0.05). The results of the study showed that there was an increase in blood glucose levels in all treatments. However, the highest increase in blood glucose levels is in K3 (67.59 mg / dl). From the results of the study, it was concluded that carbonated drinks can affect blood glucose levels in mice, but this increase is still within normal limits.
