Abstract

This study aims to analyze carbon emissions from motor vehicles and the potential for carbon absorption by vegetation on four main roads in Bengkulu City: Padang Jati, Hibrida, Pagar Dewa, and Sukarami. The approach used is quantitative-descriptive, with data collected through traffic surveys and direct measurements of vegetation parameters during the observation period. Emissions are calculated using emission factors based on IPCC/KLHK standards according to vehicle type, while tree biomass is analyzed using allometric equations based on trunk diameter, track length, and vegetation type. Carbon analysis on four roads in Bengkulu City shows a significant imbalance between vehicle emissions and vegetation absorption. Sukarami recorded the highest emissions (751,813 kg CO₂) with a biomass of only 24,053 kg (absorption of 40,607 kg), making it a carbon source. Conversely, Padang Jati had the largest biomass (881,578 kg) compared to emissions of 431,889 kg CO₂, making it a carbon sink with absorption of 344%. Hibrida and Pagar Dewa showed intermediate conditions, with emissions of 424,145–570,063 kg CO₂ and absorption of 544,349–947 kg, indicating an unbalanced absorption capacity. These results emphasize the need to increase vegetation cover and manage green spaces as strategies for mitigating urban climate change.

Abstract

Malayan soft- shelled Turtle (Dogania subplana) is a species of freshwater softshell turtle that inhabits streams and swamps. This species is considered threatened with extinction and is listed in Appendix III of CITES and as Least Concern by the IUCN. This study aims to design an artificial habitat as a conservation effort and to identify the behavioral adaptations of Dogania subplana. The research method used an ecology-based design. The research subjects were five individuals of D. subplana, consisting of three females and two males. Data collection methods included field observation, literature review, and documentation. Research instruments involved environmental sensors to measure abiotic data. Data analysis was conducted both qualitatively and quantitatively. Qualitative data were analyzed descriptively through systematic and accurate reviews based on field findings and supported with photographic documentation. Quantitative data were analyzed using the average percentage of observed behaviors, presented in graphs, and supported by measured environmental abiotic data. The study results outline the stages of artificial habitat design for D. subplana, which include: location design, area division based on function, addition of supporting biota, fencing, and acclimatization. Observations revealed three behaviors feeding, basking, and aggression which were influenced by environmental temperatures from 26–31°C. D. subplana behaviors were observed only in aquatic areas with sandy and rocky substrates, indicating that such behaviors are strongly influenced by both terrestrial and aquatic environmental conditions. The study concludes that the artificial habitat at the Turtle Learning Center (TLC) of the University of Bengkulu, designed with three zones land, mud, and water effectively supports the natural adaptations and activities of D. subplana, as indicated by their feeding, basking, and aggressive behaviors.

Abstract

This research is crucial in the context of the rising global prevalence of diabetes, a metabolic disorder that significantly affects public health. This study aims to determine the effect of salung leaf extract (Psychotria viridiflora) on blood glucose levels in hyperglycemic mice (Mus musculus). The study used 25 mice (Mus musculus) weighing 20-40 grams, divided into 5 treatment groups (P). Each group consisted of 5 mice, including a negative control, positive control, and three experimental groups with the administration of P. viridiflora extract at various doses (0.0112; 0.0225; and 0.0337 g/kgBW). Blood glucose measurements were conducted four times, on days 0, 6, 12, and 18, which included an initial glucose measurement, post-alloxan induction, and subsequent measurements after treatment. Among the three tested doses, the highest dose (0.0337 g/kg BW) proved to be the most effective in reducing blood sugar levels in alloxan-induced M. musculus, with effectiveness comparable to the standard drug Glibenclamide. Thus, the extract of P. viridiflora leaves shows strong potential as an alternative herbal antidiabetic therapy for M. musculus.

Abstract

Lotus adalah tanaman air yang memiliki habitat alami di rawa atau tempat berlumpur. Pertumbuhan dan perkembangan lotus perlu dikaji lebih dalam untuk mempermudah proses budidaya. Budidaya lotus di bengkulu masih terbilang minim, meskipun di beberapa daerah sudah ada hanya dijadikan sebagai tanaman hias. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan perkembangan lotus di kolam sains Universitas Bengkulu. Pengamatan dilakukan pada 4 stasiun penelitian dengan variasi ketinggian air dan lumpur yang berbeda. Parameter pertumbuhan lotus yang diamati adalah pertumbuhan biji (pertumbuhan tunas, jumlah tunas, jumlah daun, jumlah akar dan panjang akar), pertumbuhan bibit (jumlah daun, diameter daun, jumlah rimpang dan perbandingan pertumbuhan daun melayang dan daun koin), dan pemanenan (pertumbuhan bunga dan biji yang dihasilkan) dan dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa pertumbuhan bibit lebih maksimal dari biji yang memiliki ciri dengan bentuk membulat sempurna, tidak kisut dan tidak berjamur. Lokasi terbaik untuk pertumbuhan dan perkembangan lotus yaitu pada plot 2 dilihat dari laju pertumbuhan yang lebih cepat dibandingkan plot 1, plot 3 dan plot 4 dengan Parameter pertumbuhan pada plot 2 memiliki rata-rata diameter daun 66,3 mm, jumlah daun 5 helai, diameter tangkai daun 2 mm, dan jumlah rimpang 5 ruas. Jumlah biji yang dihasilkan memiliki rata-rata 28 terdiri dari 19 biji fertil dan 9 biji infertil. Pertumbuhan dan perkembangan tanaman lotus di kolam sains lebih maksimal dengan ciri lokasi yaitu kedalaman lumpur 62 cm dan kedalaman air 21 cm. Bunga lotus lebih banyak menghasilkan biji fertil dibandingkan dengan biji infertil yang menunjukkan tingkat keberhasilan penyerbukan tinggi.

Abstract

Science learning in schools tends to be theoretical and less related to real contexts, so students have difficulty understanding the application of concepts in everyday life. One of the causes is the lack of teaching materials that integrate local wisdom. This study aims to examine the concepts of science in the local wisdom of making Batik Besurek to be developed as ethnoscience content in integrated science e-books and to determine the level of validity and student response to the product. The method used is research and development (R&D), according to Borg and Gall (1983), using the Model of Educational Reconstruction (MER) approach. Data were obtained through questionnaires, observations, and interviews. The results of the study showed that the process of making Batik Besurek contains the concepts of temperature and heat, expansion, changes in the state of matter, physical changes, heat transfer, and Black's principle, which can be integrated into the content of the Integrated Science Electronic Book. The developed electronic book obtained a very high level of validity with an average V index of 0.86 and a percent agreement of 89.27%. The students' response to the book was also excellent, with an average percentage of 89.42%. The results concluded that the Integrated Science electronic book containing the ethnoscience of Batik Besurek Bengkulu was considered valid teaching material worthy of being tested for effectiveness in future research.

Abstract

This community service aims to equip students and teachers of SMP IT Khoiru Ummah Rejang Lebong with knowledge about managing school gardens using household waste through ecoenzymes, natural boosters, and POC. This school has a large area of underutilized land, especially for organic waste management. Household waste is not managed correctly, and most of it is disposed of in landfills, even though it can be processed into valuable products. Converting organic waste into eco-enzymes is expected to reduce waste and create a greener, more environmentally friendly school ecosystem. This training was carried out from April to December 2024, by using the Participatory Action Research (PAR) method, divided into three stages: exploration, provision of materials and practice, and evaluation. The evaluation's student response data show that around 61% of students demonstrated excellent knowledge, 30% good, and 9% sufficient. The level of concern for the environment was very high. The success of this activity was measured by the level of participation and enthusiasm among participants, which reflected the objectives of community service: increasing awareness and skills in waste management. Further evaluation is needed to assess the long-term impacts and to determine how this activity can be implemented outside of school, thereby providing benefits to the surrounding community.

Abstract

Training digital-based authentic assessments is essential due to decontextualization challenges and technological advancements in learning assessment. Transformative schools require teachers to design innovative assessments supporting differentiated learning in the independent curriculum implementation, yet many face difficulties in creating assessments aligned with new learning paradigms. This study implemented the ICARE framework (Introduction, Connection, Application, Reflection, and Extend) to enhance teachers' competencies in designing digital-based authentic assessments at SMPN 02 Tebat Karai and SMPN 02 Kepahiang. Thirty teachers from various subjects with 1-20+ years of teaching experience participated in this professional development program. Data were collected through Socrative application reflection and semi-structured interviews, analyzed descriptively across three experience groups. Results showed that most teachers successfully implemented the independent curriculum and demonstrated proficiency in diagnostic, formative, and summative assessments. Observation and project assessments were most widely used during learning processes. Teachers exhibited competence with digital tools including Google Forms, Quizizz, and Socrative. Assessment preferences varied across experience groups, with performance and portfolio assessments predominating. The ICARE framework effectively developed teachers' competencies in designing digital-based authentic assessments aligned with learning objectives and differentiated learning principles. This study contributes practical frameworks for teacher professional development in authentic assessment within Indonesian transformative school contexts, providing evidence-based guidelines for enhancing assessment literacy. Future research should investigate long-term impacts on student learning outcomes and explore scalability across diverse educational settings.

Abstract

Kolesterol dibutuhkan tubuh dalam jumlah tertentu, namun jika berlebihan dapat menyebabkan hiperkolesterolemia yang berisiko memicu penyakit jantung, stroke, dan gangguan kesehatan lainnya. Penelitian ini bertujuan untuk mengevaluasi efek anti-hiperkolesterolemia dari ekstrak pisang Barlin (Musa acuminata AA) pada mencit jantan (Mus musculus). Sebanyak 25 ekor mencit dibagi dalam lima kelompok perlakuan selama 28 hari, termasuk kelompok K (-) kontrol negatif, pakan standar, K (+) kontrol positif pakan standar, Pakan Tinggi Lemak (PTL) dengan Simvastatin 20 mg/kg BB, P(1) diberi pakan standar, PTL, ekstrak kulit M acumniata AA 0,4 mL/kg BB, P(2) diberi pakan standar, PTL, ekstrak buah M acumniata AA 0,4 mL/kg BB, dan P(3) diberi pakan standar, PTL, ekstrak kulit dengan buah M acumniata AA 0,4 mL/kg BB. Parameter yang diamati meliputi berat badan serta kadar kolesterol total (CT), trigliserida (TG), HDL, dan LDL menggunakan alat Autocheck Cholesterol Strips/ Lipid Pro. Hasil menunjukkan bahwa pemberian ekstrak buah M. acuminata AA secara signifikan menurunkan CT, TG, dan LDL, serta meningkatkan HDL, dengan efek setara Simvastatin. Ekstrak kulit dan kombinasi buah dengan kulit menunjukkan efektivitas lebih rendah. Kesimpulannya ekstrak buah M. acuminata AA berpotensi sebagai agen anti-hiperkolesterolemia, diduga karena kandungan pati resisten, flavonoid, magnesium, dan saponin yang tidak ditemukan pada ekstrak kulit.
