Abstract

The mangrove forest has unique characteristics, plays a role in ecological and economic functions, and is a natural resource that has not been optimally utilized. This research was conducted in Tungkal 1 Village, Tanjung Jabung Barat Regency, Jambi, to identify the potential utilization of mangrove plants as entrepreneur-based products. The research method involved surveys selected using snowball sampling, interviews with various stakeholders, and data analysis on respondent characteristics, knowledge, understanding, mangrove-based products, community involvement, support, accessibility, and economically valuable strategies for utilizing mangrove plants. The results show that the majority of the community has knowledge about mangrove forests, but their understanding of the potential utilization is still low. Mangrove-based products such as ecotourism, handicrafts, and sustainable fish farming have high economic potential. The level of community involvement in mangrove conservation and support for preservation efforts is high. In conclusion, mangrove management in Tungkal 1 Village can serve as a successful example in supporting sustainable local economic growth while preserving the important

Abstract

Ethnoscience can be used and integrated into various learning models, one of which is the 21st century learning model in the form of a Project based learning (PjBL) learning model with an ethnoscience approach. This research was conducted in Kerinci Regency and Sungai Banyak City, precisely at SMA Negeri 1 Sungai Banyak and the Kerinci Incung batik studio, this study aims to produce ethnoscience-based teaching modules that can improve students' understanding of plants through a local cultural approach. The research method used is the ADDIE development model, the results of the material expert validation were 98.60% and the results of the media expert validation were 96.30% with a very valid category and feasible to be applied. Continued with product trials using random sampling data collection techniques and involving classes XA and % with practical and very practical categories. Practicality tests were also conducted on six biology teachers in class X obtained with percentages, namely: 75%; 100%; 91.25%; 93.75%; 89.16%; and 95.41% with an average category of very practical

Abstract

Research on the use of water hyacinth (WH) to improve the quality of polluted water has been widely reported, but discussions on the ability of WH to clear turbid water are still rare. This research examines the possibility of using WH as a natural clarifier for Lake Bata. Treatments with 3 variations in the percentage of lake closure with WH cultivation (25, 50, and 75%) were applied for 40 days with 3 repetitions. Water quality and turbidity measurements were carried out every 4 days. The data was analyzed descriptively in graphical form to see a model of these changes. It was found that the pollutants Fe, Hg, nitrate, phosphate and ammonia were present in very small and safe quantities, but the water turbidity level did not meet the standards of the Indonesian Minister of Health yet. During the WH growth, the turbidity decreasing follows the equation Y(25) = - 0.114x + 28.52; Y(50) = -0.195x + 29.83; and Y(75) = -0.235x + 30.14 for cover percentages of 25, 50 and 75% respectively, where y for the turbidity (NTU) and x for WH growth time (days). To meet turbidity standards, WH coverage percentages of 25, 50, and 75%, require cultivation periods of 32, 28, and 24 days, respectively.

Abstract

The 21st century learning paradigm emphasizes students' ability to think critically, be able to connect knowledge with the real world, master information technology, communicate and collaborate. This study aims to determine how the flipped classroom model affects students' critical thinking and communication skills. The research method is a quasi-experimental form of non-equivalent pretest-posttest control group design with a simple random sampling technique. The population in this study were all students of grade IX of SMP Islam Al-Falah, namely 5 classes, class IX-1, IX-2, IX-3, IX-4 and IX-5., the research sample class IX-5 as the control class and IX-3 as the experimental class. The data collection technique used the FRISCO indicator critical thinking ability essay test and the communication ability assessment observation sheet. The data analysis technique used the one-way MANCOVA test with initial critical thinking and communication skills as covariates. The results of the hypothesis test showed that the value [F (2,51) = 22.777, p <0.001, ηp2 = 0.472]. This means that the significance value of p <0.001 which means <0.05, then H0 is rejected and H1 is accepted, meaning that there is an influence of the flipped classroom model on students' critical thinking and communication skills. The size of the effect size value ηp2 = 0.472, which means that there is a large influence of the flipped classroom model on students' critical thinking and communication skills.
