Abstract

Sayung District is one of the district in Demak Regency which has mangrove vegetation. The alteration of Demak Regency's coastal areas caused by the sea rob phenomenon has a significant impact on the mangrove vegetation. The Semarang-Demak toll road construction along Sayung coast potentially causes mangrove damage. The purpose of this study is to determine the structure and profile, and analyze the condition of mangrove vegetation in Sayung, based on the structure and profile of Sayung mangrove vegetation. The study was conducted on the mangroves of Bedono, Mondoliko, and Morosari Village. This research used an exploratory method with descriptive analysis, by collecting data on vegetation parameters and vegetation profiles. The results showed that the types of mangroves found at all observation stations consisted of Avicennia, Bruguiera, and Rhizophora. The profile graph shows an association between Avicennia alba, Avicennia marina, and Rhizophora mucronata. Important Value Index (IVI) for all stations shows that Avicennia officinalis have highest value on 65,30 and 50,18 respectively. Diversity index shows that both stations have value on 0,873 and 0,893 which belongs to low diversity. Similarity index on each sub-stations shows the significant difference between Bedono-A, Bedono-C, Mondoliko, and Morosari stations at 0,4 index, Based on Abiotic parameters such as pH, salinity, and water temperature found on the optimal quality standard level. The conclusion is mangrove vegetation structure dominated by Avicennia and Rhizophora groups, with a low level of diversity at all observation stations.

Abstract

Indonesia has a high and continually increasing total greenhouse gas emission. Carbon dioxide absorption can be mitigated by utilizing the photosynthesis process of microalgae. Spirulina platensis was chosen as the sample to be cultivated in this study due to its ease of cultivation and its status as a large-scale carbon dioxide absorber. The objective of this research is to analyze the effect of varying carbon dioxide injection rates on dissolved oxygen and the growth of S. platensis. This research employed an experimental method involving semi-mass cultivation using a 12 L volume tube photobioreactor (PBR) as a container with three treatment variations. These variations included culture P0 (without injection/control), culture PA (0.5 L/minute), and culture PB (1 L/minute). The data analysis revealed that the variation with an increase in dissolved oxygen levels and enhanced growth of S. platensis was most optimal in culture PB (1 L/min). One-way ANOVA results showed significant differences between culture P0 (without injection) and classified data indicating that culture PB (1 L/min) fell into a high-level classification. The average dissolved oxygen value for culture PB (1 L/min) was 7.9 mg/L, with a cell density average of 0.651 cells/ml and a dry biomass weight of 3.8 grams. The conclusion drawn is that varying carbon dioxide injection rates significantly affect dissolved oxygen levels and the growth of S. platensis, as evidenced by cell density and biomass calculations. The effect on the S. platensis culture is a notable increase in both parameters. The application of varying carbon dioxide injection rates in the cultivation of S. platensis may serve as a reference for identifying the optimal carbon dioxide injection rate during semi-mass cultivation.

Abstract

Penelitian ini bertujuan untuk mengkaji keanekaragaman pohon serta status konservasinya di kawasan Fakultas Matematika dan Ilmu Pengetahuan Alam (FMIPA) Universitas Negeri Semarang (UNNES) sebagai bagian dari strategi konservasi dan mitigasi triple planetary crisis. Metode penelitian yang digunakan adalah survei eksplorasi dengan teknik jelajah pada seluruh area FMIPA, di mana setiap pohon diidentifikasi berdasarkan nama lokal dan ilmiah serta dihitung jumlah individunya. Data dianalisis menggunakan indeks keanekaragaman Shannon-Wiener (H’), sedangkan status konservasi mengacu pada IUCN Red List. Hasil inventarisasi menunjukkan terdapat 318 individu pohon yang tergolong dalam 58 spesies. Spesies yang paling dominan adalah Swietenia mahagoni (76 individu), Mangifera indica (45 individu), Polyalthia longifolia (39 individu), dan Roystonea regia (26 individu). Nilai indeks Shannon-Wiener sebesar H’ = 2,95 termasuk kategori sedang menuju tinggi, menandakan komunitas pohon di FMIPA cukup beragam dan stabil. Berdasarkan status konservasi, sebagian besar spesies termasuk kategori Least Concern (LC), namun ditemukan pula spesies yang tidak umum, yaitu Pterocarpus indicus berstatus Endangered (EN) dan Swietenia mahagoni berstatus Near Threatened (NT). Keberadaan spesies langka tersebut memperkuat peran FMIPA UNNES tidak hanya sebagai ruang terbuka hijau penyerap karbon, tetapi juga sebagai kantong konservasi keanekaragaman hayati di kawasan kampus. Dengan demikian, hasil penelitian ini dapat dijadikan dasar strategi konservasi kampus yang mendukung upaya mitigasi perubahan iklim, perlindungan biodiversitas, dan pengendalian polusi dalam kerangka triple planetary crisis serta kontribusi terhadap target nasional Net Zero Emission 2060.

Abstract

Arthropods are the largest phylum in the Animalia kingdom that can live on land, in freshwater, in the sea, or in the air. Springs are bodies of water that seep out through cracks in rocks to the surface of the ground, serving as a habitat for various Arthropods and the Gunungpati district has several springs in its area. This study aims to analyze the diversity of arthropod species and to describe the abiotic and biotic factors that influence the diversity of arthropod species in the water bodies and around the springs in the Gunungpati district, Semarang City. The research was carried out from October to December 2022, located at five springs, among others. The research was conducted from October to December 2022 at five springs, namely Sendang Jedung, Sendang Lanang Trangkil, Sendang Ndelik, Sendang Mbiru, and Sendang Gede. The data collection method was purposive sampling. The approach used in this research is a quantitative approach with a descriptive research type. The research results showed a total of 1537 individuals and 112 species of arthropods, which included 146 individuals in water bodies and 1391 individuals around springs. The diversity index ranged from moderate to high, between 1.82-3.30. The dominance index values were low, ranging from 0.05-0.29, and the evenness index values fall within moderate to high criteria, ranging from 0.52-0.86. The Sorenson similarity index on the five ponds is considered low. Abiotic factors do not affect diversity too much because it has similar values in the five springs. Therefore, biotic factors (organic matter, litter, and surrounding vegetation) greatly influenced the diversity of arthropod species in water bodies and around the spring in Gunungpati District, Semarang City.

Abstract

The demands of digital transformation in the 21st century require continuous innovation in the design of science teaching materials, especially to replace static printed instruments. The integration digital worksheets presented in flipbook format  with Augmented Reality (AR) technology offers strategic potential in visualizing abstract concepts of Natural Sciences (IPA) into immersive and interactive three-dimensional representations. This Systematic Literature Review (SLR) research aims to map research trends, evaluate the level of validity and practicality of media, and identify research gaps related to the use of these technologies. This review was limited to 15 peer-reviewed primary articles  indexed in academic databases in the 2020 to 2026 publication range. The results of the analysis show that all AR-visualized digital worksheet  developed achieve a very valid and practical predicate. Empirically, this fusion of technology has proven to be effective in reducing cognitive burden, shifting the learning paradigm to student-centered, and significantly spurring student motivation and learning outcomes. However, the findings reveal that the current research focus is still concentrated at the high school level for abstract materials (Biology and Chemistry) and has not targeted the integration of Higher Order Thinking Skills (HOTS) assessments in depth. This SLR concludes that the future development of digital worksheets-AR must go beyond the feasibility of basic media by adopting high-level reasoning instruments and expanding the scale of testing to the higher education level.

Abstract

The latest Programme for International Student Assessment assesses competencies in the context of environmental issues, making the strengthening of environmental education crucial for enhancing students' environmental literacy. This study aims to analyze the trends, implementation, and dominant topics of environmental literacy in primary to secondary education. A systematic literature review (SLR) was conducted following the PRISMA protocol. A primary data search was performed on the Scopus database using the keyword "environmental literacy" for the 2016-2025 period, which yielded 22 journal articles that met the inclusion criteria. The analysis results show that environmental literacy is measured through four domains: knowledge, skills, attitudes, and responsible behavior. The most dominant measurement method was questionnaires, while the learning approaches included educational games, environmental projects, and problem-based models. The collaboration of activities, surveys, models, and learning media can enable the measurement of environmental literacy to fulfill its domains. Environmental literacy is increasingly oriented towards environmental education and environmental issues, considering effectiveness, awareness, behavior, and learning models. Effective implementation must integrate problem-based learning models that connect local environmental issues with indigenous wisdom, alongside interactive media and educational projects. This study contributes by emphasizing the balance between assessment and authentic learning experience for environmental literacy aligned with Programme for International Student Assessment competencies.

Abstract

This Systematic Literature Review (SLR) aims to map trends, development methods, and the feasibility of Higher Order Thinking Skills (HOTS)-based cognitive assessment instruments for the 2019–2025 period. Using the PRISMA 2020 approach, 31 relevant articles were selected from academic databases for analysis using Biblioshiny and VOSviewer. The review results indicate a dominant shift to Complex Multiple Choice (41.7%) and Structured Essay (33.3%) formats. The Research and Development (R&D) method, using the ADDIE model, has become the primary instrument for assessing critical thinking and problem-solving skills (C4–C5) across various disciplines. Although the developed instrument has demonstrated high validity and reliability through expert testing and Confirmatory Factor Analysis (CFA), this study identifies crucial challenges in the field. The findings indicate low teacher pedagogical readiness (80.6%) and low student learning completion rates during the implementation stage, underscoring the need to strengthen educators' capacity to implement HOTS-based assessments effectively.

Abstract

Using the environment as a learning environment has great potential to be developed. Biodiversity in Indonesia, including the slopes of Mount Muria, can be used as a source of learning for student participants. Previous studies' results stated that students' Science Literacy and creative thinking skills on Mount Muria's slopes need improvement. There needs to be learning that can trigger and train students' Science Literacy and creative thinking skills to improve these abilities. The science, technology, religious, engineering, art, and mathematics (STREAM) approach can present more meaningful learning, especially if integrated with project-based learning models and IT. This study aims to develop a digital worksheet titled Kehatimu (Keanekaragaman Hayati Muria) with the PjBL STREAM model to improve students' science literacy and creative thinking skills. The method used is R&D with the define, design, development, and disseminate (4D) model. Data collection involved both test instruments (science literacy and creative thinking assessments) and non-test instruments (feasibility and readability questionnaires, as well as attitudinal scales toward science literacy and garden design creativity assessment rubric). The study involved 135 students from three schools located on the slopes of Mount Muria, divided into experimental and control groups. Data analysis using SPSS included the N-Gain and independent t-tests. Expert validation yielded a feasibility score of 0.90 (categorized as very feasible), while readability analysis scored 4.3 (high readability). Results demonstrated that the digital worksheet is interactive, user-friendly, relevant, and contextually grounded. Furthermore, significant improvements (p < 0.05) were observed in both scientific literacy and creative thinking scores, with averages exceeding the Learning Mastery Level (LML) threshold of 70. In conclusion, the Kehatimu digital worksheet can improve students' scientific literacy and creative thinking related to Mount Muria’s biodiversity.
