The Effect of Cooperative Model-Integrated Huyula Local Wisdom Values on Mastery Concepts of Simple Machine Material
No full textThe learning model can be interpreted as a whole series of material presentations that include all aspects before, during and after learning. This study aims to examine the effect of applying a cooperative model integrated with local wisdom values on the mastery of the concept of simple aircraft research at SMP Negeri 1 Telaga Biru. The research design used a One-Shot Case Study by using one class as a sample. The results showed a significant increase in student learning outcomes after being treated using a cooperative model integrated with local wisdom values. The use of cooperative models integrated with local wisdom values increases the active involvement of students in discussions and cooperation, so as to improve understanding of concepts and the ability to carry out activities that are directly related to the concept of simple aircraft material. Data analysis shows that the average posttest score is higher than the learning objectives achievement criteria (KKTP). The results showed the criteria for testing the hypothesis of a one-sample t-test, tcount ≥ ttable, with α level = 0.05 for the experimental class, t table value (2.0096). This indicates that the cooperative model integrated with local wisdom values can improve students' learning outcomes in understanding the concept of simple aircraft material. This study concludes that the application of the cooperative model integrated with local wisdom values is effective because it involves students actively in the process of cooperation and discussion, thus strengthening their understanding of the material and achieving learning outcomes

A DNA Barcoding Multilocus Analysis in the Cucurbitaceae Family
Get PDFThe Cucurbitaceae family is a very diverse family of angiosperms and is often used as a traditional medicine because it produces secondary metabolites in the form of Cucurbitacin B, D, E, and I. The identification and determination of filogeny between species in the Cucurbitaceae family using a single DNA barcode locus is still inefficient. The purpose of this study is to analyze the appropriate and effective combination of DNA barcode multiloci for species identification from the Cucurbitaceae family. The materials used in this study are the database ofns matK, rbcL, ITS and trnL-F IGS from the Cucurbitaceae Family and the outgroup, namely Tetrameles nudiflora which was explored from Genbank through the NCBI website, and then performed MSA (Multiple Sequence Alignment) using MAFFT v.7 software. and sequence editing using Bioedit v.7.2. then DNA sequence analysis and phylogenetic tree construction using MEGA 11. The results show that the ITS locus is the most efficient barcode to identify and distinguish species in the Cucurbitaceae family. The combination of multiloci of the ITS, matk, and trnL-trnF IGS also has the potential to identify and differentiate species in the Cucurbitaceae family on the condition that ITS must be included (be the main locus) and not include rbcL because of its low variability

Get PDFDepression is a common mental health disorder in the elderly, often coexisting with chronic conditions like hypertension. This study examines the relationship between depression and hypertension stage 2 among elderly individuals at Puskesmas Karang Taliwang, considering age and gender. A cross-sectional study of 30 elderly patients used a validated questionnaire to assess depressive symptoms. Results showed a significant association between age (≥60 years) and depression, while gender had no statistical correlation. Hypertension stage 2 was also significantly linked to depression, though with a small effect size. These findings highlight the need for integrated healthcare strategies addressing both mental and cardiovascular health in the elderly. Further research is needed to explore underlying mechanisms and potential interventions
Morphometric Analysis of Apis dorsata Bees in North Lombok Regency
Get PDFThe giant honeybee (Apis dorsata) is vital for ecosystems as a pollinator, significantly impacting agricultural productivity, biodiversity, and food sustainability. This study explores the morphometric characteristics of Apis dorsata populations in Batu Rakit Village, North Lombok Regency, a tropical region with rich biodiversity. Morphometric data were collected from 20 worker bees, focusing on body length, abdomen dimensions, wing dimensions, proboscis length, and body weight. Measurements were analyzed using descriptive statistics, correlation, and regression to identify significant relationships between morphometric traits and body weight. Results show that abdomen length (r = 0.50, β = 0.05, p = 0.01) and forewing length (r = 0.48, β = 0.08, p = 0.03) are the strongest predictors of body weight, underscoring their roles in resource storage and flight efficiency. Most traits exhibited low variability, reflecting evolutionary adaptations to environmental stability, while body weight displayed high variability (CV = 7.53%), indicating responses to environmental and individual factors. These findings highlight the ecological importance of uniform traits such as abdomen length and wing dimensions in supporting the foraging efficiency and resource transport of Apis dorsata. This study provides critical insights for the conservation and management of Apis dorsata populations in tropical ecosystems
