Abstract

Samin is one of watersheds located in the districts of Karanganyar and Sukoharjo, Central Java, Indonesia. Samin is a part of Bengawan Solo watershed that is classified into one of 282 Indonesian watersheds which are in critical condition. Research about vegetation analysis of Samin watershed as conservation efforts have been done before and resulted in structure of lower crop community (LCC) and tree vegetation. The purpose of this study was to analyze potential plants, both LCC and trees, in Samin watershed that could be developed as a vegetative water and soil conservation. The list of plants that were potentially developed as a vegetative conservation obtained from the research before about analysis structure and composition of vegetation in Samin watershed and literature review. The result of this research showed that there were several plants with the highest Important Value Index (IVI) and that can be developed for vegetative soil and water conservation. In tree vegetation, there are Tectona grandis, Delonix regia, Switenia mahagoni, Cassia siamea, and Samanea saman. These tree plants have a big canopy that can retain rain water through several mechanismssuch as interception, reducing direct flow, and producing litter layer. In LCC vegetation, there were Mimosa pudica, Ageratum conyzoides, Tridax procumbens, Oplismenus burmanii, Chloris barbata, and Axonopus compressus. Grass vegetation could withstand runoff and increase infiltration.

Abstract

In the era of the Fourth Industrial Revolution, it is essential to develop competitive individuals equipped with Science, Technology, Engineering, and Mathematics (STEM) competencies. The government, actively promotes the integration of STEM across all educational levels, including secondary schools. This emphasis arises because STEM competencies are critical for the Fourth Industrial Revolution and help individuals address real-world challenges. This literature review explores the implementation of STEM in Indonesia, focusing on the tools and strategies applied in secondary education. Over the past six years (2016–2021), changes in STEM practices have been identified. From 25 articles were analyzed, covering aspects such as instructional materials and pedagogical strategies in secondary schools. The findings reveal the distribution of resources as follows: curriculum score 7.69%, lesson plans 20.51%, modules 15.38%, student worksheets 33.33%, books 10.25%, exam questions 10.25%, and curriculum documents 2.56%. In terms of teaching approaches, the data show 4% engagement in discovery-based learning, 52% in project-based learning, 36% in problem-based learning, and 4% in scientific learning. Overall, the results indicate that STEM competencies are still not widely implemented in Indonesia, as most scores remain at or below 50%. Thus, further efforts are necessary to strengthen STEM integration in the country.

Abstract

The study aims to test the bioremediation potential of Nannochloropsis sp. against Pb (lead) contamination in the batik textile industrial area. The steps in this study include collecting river water samples from 3 different stations, preparing the samples by adding HNO3, culturing Nannochloropsis sp. seed for 7 days, testing the initial Pb metal content before and after treatment with Nannochloropsis sp. using wet-digestion techniques, and analyzing the samples. The water samples were taken from upstream, midstream, and downstream. The water samples were then preserved with HNO3. After that, Nannochloropsis sp. cultures were conducted, and results showed an increase in algal population after 7 days. Subsequently, metal content testing was conducted using AAS (Atomic Absorption Spectrophotometer) with a wet-digestion technique to eliminate organic substances in the samples from each station. Metal content testing was conducted before and after treatment with algae. The results of this study showed a decrease in Pb metal levels at each station in the Jenes River after treatment with algae and 7 days of culture. The average decrease obtained was 14.0 before treatment and 5.0 after treatment. Nannochloropsis sp. is an important bioremediation agent for degrading Pb (lead) contamination in river water resulting from excessive industrial waste. These findings contribute to the development of waste treatment to preserve the river ecosystem.

Abstract

This study aims to inventory the types of food crops growing around tailings ponds and to quantify mercury concentrations in food crop tissues growing in the area around the gold mine. The samples taken are plants consumed by residents. Mercury content testing uses a mercury analyzer. The results of the study showed that from 4 observation locations, a total of 11 types of food crops were found, all of which contained mercury (Hg) with a concentration range of 0.01-0.54 mg/kg. Similarly, the soil as a growing medium contains quite high levels of mercury at location 1, namely 54.36 mg/kg, and the lowest at location 3 at 0.12 mg/kg. The concentration of mercury in vegetable leaves is much higher than in other organs such as tubers, flowers, and fruits. Furthermore, to plant plants for consumption, it is best to pay attention to the condition of the growing medium, as a prevention of heavy metal (mercury) contamination, such as the environment (air, soil, water) that is far from waste retention ponds or waste discharge streams containing heavy metals (mercury).

Abstract

One of the Basic Competencies (KD) in Biology for Indonesian Senior High School is KD 4.12 which reads "Presents observations of the process of mitosis in the onion root and determines the phases it finds". Based on the basic competency test, students are required to have skills in making and observing mitotic preparations of plant tissue with at least using onion. Observation of mitotic division in plant tissues requires skill in making preparations. Making preparations in observing cells and tissues of plants or animals needs staining. Dyes often used in lab work are synthetic dyes. One of the synthetic dyes commonly used is safranin. However, safranin is quite expensive. This limitation requires teachers to look for alternatives to synthetic dyes that are easily found at a more affordable price, namely with natural dyes. One of the plants that has the potential to overcome this issue is beetroot (Beta vulgaris). The purpose of this study was to determine the quality of plant tissue preparations (Allium cepa) stained with beetroot skin (Beta vulgaris) as a natural coloring agent. The research method used was an experimental method with a Completely Randomized Design consisting of two factors, namely the staining time (1 hour, 2 hours, and 3 hours) and the type of solvent (aquades and citric acid 10%). The results of the study were analyzed with qualitative descriptive methods which included contrast and clarity of the preparations. Based on the results of the study, the quality of Allium cepa root preparations using beetroot (Beta vulgaris) skin extract with variations in the type of solvent and duration of staining showed good results on the staining time of 1 hour and 2 hours. The staining time of the preparations can affect the contrast and clarity of the preparations.

Abstract

Life skills are needed in this era of globalization to be successful in the school environment or outside of school. According to the 2019 World Economic Forum, the world's demand for STEM qualifications and skills is very high now and is likely to continue to increase in the future. Today, 75% of the fastest-growing industrial-scale jobs require skilled STEM workers. Faced with this, to be able to compete, the world of work requires people who can adapt to their new work environment. STEM can empower individuals with the skills to succeed and adapt to new work environments. To get individuals who have STEM skills, individuals who have 21st-century skills are needed. This is because in 21st-century skills 3 skills must be met, namely learning skills, reading and writing skills, and life skills. The purpose of this study was to determine the feasibility of the PBL-STEM module developed for prospective Biology teacher students as an effort to improve 21st-century skills. The method used was the Rosset-based RnD ADDIE model. The ADDIE Teaching Model includes 5 stages, namely analysis, design, development, implementation, and evaluation. The results of the material expert validation show that the average score of the material expert validation results shows a fairly good category with an average of 2.94. The results of practitioner validation show that the average score of practitioner validation results shows a good category with an average of 3.56. The results of the small group readability test showed that the average score on the small group readability test was in the good category with an average score of 3.39.
