Abstract

Freshwater crayfish (Cherax quadricarinatus) is a valuable aquaculture commodity with relatively easy cultivation. However, low larval survival during early developmental stages remains a major challenge in its farming. This study aims to evaluate the effects of dissolved glucose and amino acid combinations on growth characteristics, molting frequency, and survival rate. The research was conducted in the Greenhouse of the Faculty of Agriculture, Animal Husbandry, and Fisheries, Universitas Muhammadiyah Parepare, using hatchery-produced crayfish larvae. Four dosage combinations were tested: A) 100 ppm glucose + 250 ppm amino acids, B) 150 ppm glucose + 200 ppm amino acids, C) 200 ppm glucose + 150 ppm amino acids, and D) 250 ppm glucose + 100 ppm amino acids, each replicated three times. The results showed that glucose and amino acid combinations significantly affected crayfish length growth. The highest absolute length growth was observed in the 250 ppm glucose + 100 ppm amino acid group. Meanwhile, the 150 ppm glucose + 200 ppm amino acid combination showed the best performance in molting frequency, number of molting crayfish, survival rate, and percentage of surviving crayfish. The optimal treatment for supporting freshwater crayfish growth and development was the 150 ppm glucose + 200 ppm amino acid combination.Keywords:Cherax quadricarinatusGlucoseamino acidsgrowth characteristicssurvival ratemolting

Abstract

This study aims to produce teaching materials in Electronic Student Worksheets (E-LKPD) based on STEM in an Islamic context to improve creative thinking skills in the human digestive system. The development process involved validity testing by six experts, readability testing by 18 students, and field trials by one biology teacher and 36 students. The study results indicate that the developed E-LKPD is highly valid and effective. The E-LKPD achieved an average validity rating of 90.87%, classified as feasible. Regarding readability, it scored an average of 98.84%, indicating it is highly appropriate for users. Furthermore, field trials revealed positive feedback from teachers and students, with feasibility ratings of 91.26% and 98.49%, respectively, confirming that the E-LKPD is very well-received and effective in practical use. There is an increase in the average ability to think creatively as measured through test instruments. The study significantly enhances students' creative thinking abilities by implementing E-LKPD. Before using E-LKPD, the average creative thinking score was 34.86, which increased to 72.08 after implementation, with an N-Gain of 0.55, categorized as medium. These results demonstrate that E-LKPD is highly suitable for learning activities and effectively improves students' creative thinking skills.

Abstract

Problem-based learning (PBL) is an effective pedagogy in increasing scientific literacy among students, and this strategy helps students acquire and apply knowledge and develop higher-order thinking skills that prioritize problems obtained from real life.This study aims to investigate the influence of ill-structured type problem-based learning (PBL)  model on students' science literacy skills in environmental change concept. The research was conducted at MAN 1 Pandeglang in the 2023/2024 school year using a quasi-experimental method using a non-equivalent control group design. Two classes were selected as research samples (experimental class and control class) through simple random sampling technique. Data analysis using independent samples t-test with the help of IBM SPSS Statistics 26 showed that the value of sig. (2-tailed) of 0.004, which is below the significance level of α = 0.05. These results show that the use of ill-structured type problem-based learning models has a significant influence on improving students' science literacy skills. Thus, this learning model is effective in improving science literacy skills on the concept of environmental change

Abstract

To improve student engagement and learning results, the use of technology in biology education necessitates a suitable pedagogical strategy. Nonetheless, traditional teaching approaches still predominate in classrooms, with little use of technology. The purpose of this study was to examine how using Project-Based Learning (PjBL) in conjunction with the Substitution, Augmentation, Modification, and Redefinition (SAMR) model affected students' learning results regarding the respiratory system. This study employed a non-equivalent control group design and a quasi-experimental methodology. Purposive sampling was used to pick 68 11th graders from a South Tangerang public high school for the research sample. Pretests and posttests with multiple-choice items that had undergone validity and reliability testing were used to gather data. Normalized gain (N-Gain) computation, the Shapiro-Wilk normality test, Levene's homogeneity test, and the Mann-Whitney test were used to analyze the data. According to the findings, the experimental class's average posttest score was roughly 29 points higher than the control class's. The experimental class's N-Gain value was 84.50%, or (₂g² = 0.845) (high category). The Asymp. Sig. (2-tailed) value for the Mann-Whitney test was 0.000 (0.05). These findings showed that using PjBL in conjunction with the SAMR model significantly improved students' learning outcomes.

Abstract

This study examines the collaborative governance strategy and model developed by the Makassar Berkebun Community in addressing the shortage of urban green open space in Makassar City, tracing the web of relations among the community, sub district government, and private actors that has quietly taken shape behind every campaign and educational program on urban agriculture since 2011. This reading turns attention toward a question that has long stayed in the background of the environmental communication narrative, namely who actually carries the responsibility of providing green space when the capacity of local government falls short of its residents needs. Using a qualitative case study approach, this study analyzes the collaboration pattern between the Makassar Berkebun Community and sub district government, private corporations, and foundations from 2011 to 2021. The findings show that the collaborative governance process moves through four stages, namely joint problem assessment, collaborative planning, program production, and continuous action with evaluation. This pattern reflects a shift in the role of the state from sole provider of green open space to facilitator and partner within a governance network shared with civil society and the private sector. This study contributes to the urban environmental governance literature in Indonesia by showing that the legitimacy of community leadership is a determining factor for the sustainability of three sector collaboration.
