Abstract

Digital literacy is important for every student to have. Digital literacy needs to be trained and learned to form a young generation that is digitally literate so that they are ready to participate in the digital community with confidence in communicating, sharing and distributing knowledge in a useful and efficient way, provides readiness to adapt successfully to a changing work environment and increasing self-control as a solution to the spread of false information that continues to repeat itself and is increasing in number. This research aims to measure students' digital literacy at SMAN 1 Kesesi. The methods used were filling out questionnaires and conducting interviews. Seventy-six eleventh-grade students of SMAN 1 Kesesi, Pekalongan Residence, Central Java, Indonesia, and two biology teachers were selected as the research sample in this study. The research results showed the following aspects: Firstly, the student's digital literacy questionnaire is 71%, which is classified as moderate in digital literacy indicators including finding, using sources, selecting, evaluating, considering sources, message effects, and using data to produce work; secondly, some of the things that teachers do to train these two skills are by inviting students to search for information via Google/search engines and video searches to support the teacher's explanations and using Canva to make some presentation. Unfortunately, teachers do not train them on how to search using appropriate keywords and trusted sources. Finally, teachers must be more active and innovative in maximizing the wise use of digital media to improve students' digital literacy.

Abstract

This study aims to measure the level of creative thinking skills among tenth-grade students at Public Senior High School 1 Belitang. Creative thinking skill is the ability to think in new, original, and flexible ways. It involves generating innovative ideas, solving problems in unique ways, and making connections between seemingly unrelated concepts. This skill is essential for adapting to new situations and fostering innovation across various disciplines. Creative thinking is one of the essential skills for the 21st century. This research employed a quantitative descriptive method with data collection through questionnaires and interviews. A total of 96 students participated in completing the questionnaires, and interviews were conducted with 3 biology teachers. The results showed that students' average creative thinking skills were in the medium category, with a percentage of 70%. Interviews with teachers revealed that although teaching media such as PowerPoint and student worksheets were used, creative thinking skills were not explicitly taught or assessed. These findings highlight the importance of developing more innovative teaching methods and using technology and multimedia to enhance students’ creative thinking skills.

Abstract

Orchids are ornamental plants that have high aesthetic value and beauty. Many human activities use this plant, including weddings, Christmas, New Year and birthdays. Orchid propagation can be done conventionally, but it requires a large area of land and takes a long time to grow. However, it can also be multiplied using tissue culture. Plant tissue culture techniques have better prospects than conventional propagation because tissue culture can produce large numbers of new plants without being influenced by time or season. This research aims to determine the effect of IAA and leaf order on shoot growth of Cattleya sp orchid plants. This type of research is experimental research with a Factorial Completely Randomized Design (CRD) with 12 treatments and 3 replications. There are 2 factors in this study, namely factor I PGR IAA (0, 0.5 mg/l, 1 mg/l, and 1.5 mg/l) and factor II Leaf order (1st leaf, 2nd leaf, and 3rd leaf). This research is a quantitative descriptive study with the parameters of the time of shoot emergence and using 2-way Statistics with Analysis of Variance (ANOVA) with the parameters of number of shoots, number of leaves (strands), and plantlet height. From the research results, it was found that the administration of IAA (Indole Acetic Acid) and the order of the leaves did not have a real effect on the number of shoots, number of leaves (strands) and plantlet height. However, the best treatment is the I0.5D2 treatment (IAA 0.5 mg/l and 2nd leaf).

Abstract

Pteridophyta is a pioneer plant that has an important role because it can provide benefits for human life and the environment. Pteridophyta can maintain the balance of the forest ecosystem, namely regulating water levels, helping the weathering process of forest litter, and as a soil cover in the forest, thereby preventing erosion. The distribution of Pteridophyta plant populations is influenced by several factors including humidity, light, and sufficient water sources. This study uses a descriptive exploratory method which aims to determine the types of Pteridophyta and obtain the diversity index value of Pteridophyta species in Tahura (Taman Hutan Raya) Nuraksa, West Lombok Regency. Pteridophyta sampling used the quadratic method by making plot arranged in a zigzag with a size 5m x 5m. The results showed that the number of Pteridophyta found was 18 species, 12 genera, and 8 families (Athyriaceae, Denstaedtiaceae, Dryopteridaceae, Lomariopsis, Polypodiaceae, Pteridaceae, Tectariaceae, and Thelyptheridaceae. Analysis of Pteridophyta species diversity index using the Shannon-Wiener formula and obtained a species diversity index value (H') for all species of 2.209, with a medium species diversity category. The value of this diversity index shows the amount of variation in species and growth of Pteridophyta in accordance with environmental conditions in Tahura Nuraksa.
