Abstract

Abstract: This study addresses the challenges of limited student participation and ineffective group learning in Information Systems Analysis & Design education. The objective was to develop, validate, and test a seven-syntax flipped classroom model integrated with cooperative learning. The study employed Borg and Gall's R&D methodology with 60 students in experimental and control groups at Universitas Ekasakti. Data were analyzed using descriptive statistics for validity and practicality, and independent t-tests for effectiveness. The results demonstrated exceptional model validity (≥88%), high practicality from instructors (≥85%) and students (≥86%), and significant effectiveness. The experimental group showed superior cognitive (85.2 vs. 75.1), affective (collaboration and responsibility), and psychomotor outcomes (88.5 vs. 78.2) compared to the control group. In conclusion, the validated seven-syntax model successfully improves student participation and learning outcomes by balancing asynchronous learning with synchronous collaboration, providing a valuable framework for technology education.

Abstract

Rescue, rehabilitation, and release is one of the strategies for orangutan conservation. Jerora Forest School, Sintang Orangutan Center, West Kalimantan, is a place to rehabilitate orangutan. One of the criteria for orangutan to be ready for release is the ability to build nests. The objective of this study was to analyze the nest building ability and nest characteristic preferences of four pre-release female bornean orangutans (Jamilah, Penai, Joss, and Bondan) in Jerora Forest School. Data was collected in November 2024 to January 2025 using the focal animal sampling, ad libitum sampling, and continuous recording methods. Three out of four female pre-release bornean orangutans (Jamilah, Joss, and Bondan) are categorized as moderate on their ability to build nest, while Penai is less capable. Nest trees used by the juvenile orangutan are more diverse than the ones used by the adult orangutan. The characteristics of the nests used by the research subjects were relatively similar across each age group. Nest trees used by the juvenile orangutans are more diverse than the ones used by the adult orangutans. Based on the nest building observation, Jamilah, Joss, and Bondan are ready to be released, while Penai is not ready to be released yet.

Abstract

Bornean orangutans (Pongo pygmaeus) in captivity require time to be released in order to survive in their natural habitat. This study aims to analyze the daily behavior of orangutans awaiting release at the Jerora Forest School, Sintang Orangutan Center, West Kalimantan. The study was conducted using a focused animal observation method with 5-minute intervals without breaks and without time restrictions. Observations were made on two female orangutans, Jamilah (24 years old) and Penai (21 years old). The results of the data analysis showed that Jamilah's feeding behavior occurred in the enclosure (41.89%) and cage (38.49%), while Penai's feeding behavior occurred in the enclosure (31.41%) and cage (41.22%). The least frequent behavior was playing, with Jamilah playing in the enclosure (4.87%) and cage (3.95%) and Penai playing in the enclosure (4.02%) and cage (3.84%). Jamilah's arboreal movement behavior was 62% and Penai's was 82%. The observation results indicate that Jamilah is more ready for release than Penai based on the orangutan release readiness criteria cited from the Orangutan Conservation and Reintroduction Workshop in 2002.

Abstract

West Kalimantan has different types of  wetlands  spread  across highland  and lowland areas  , including rivers, swamps, coasts,  mangrove forests, lakes, ponds, reservoirs, and paddy. One of these areas is Mempawah Regency, which is the habitat of various aquatic plants. One of the prominent species in this area is Purun, a type of weed from the Cyperaceae family. This study explores the potential of Purun plants as   a source of contextual learning and its use by the community in Segedong District. The method used is qualitative descriptive, with data collection techniques through observation, interviews, identification, documentation, and questionnaires to teachers. This study identified two types of Purun, namely the rat Purun (Eleocharis dulcis) and the lake Purun (Lepironia articulata), which are used by residents in two villages to making craft products.  This plant has great potential to be integrated into   the junior high school biology curriculum, particularly in biodiversity, classification, and ecology materials.   The results of the evaluation showed a positive perception of Purun as   a learning resource: clarity of potential (72.91%), clarity of goals (66.66%), clarity of purpose (70.83%), clarity of information (68.75%), exploration clarity (75%), and yield clarity (70.83%).

Abstract

Learning model is a strategy or planning used as a reference in the implementation of the teaching and learning process. One relevant model is Discovery Learning. This study aims to examine the differences in: scientific literacy and science learning outcomes simultaneously, scientific literacy skills, and science learning outcomes between students taught using the Discovery Learning model and those taught using the Tri Kaya Parisudha-based Discovery Learning model. The research employed a quantitative approach with a quasi-experimental method and a Nonequivalent Pretest-Posttest Control Group Design. The subjects were seventh-grade students at SMP Negeri 3 Selemadeg Timur, divided into experimental and control groups. Data collection instruments included a questionnaire to assess scientific literacy and objective tests (pretest and posttest) to measure science learning outcomes. Data were analyzed using MANCOVA. The findings revealed significant differences (p < 0.05) between the two groups in all three aspects examined: simultaneous scientific literacy and learning outcomes, scientific literacy alone, and science learning outcomes alone. These results indicate that the Tri Kaya Parisudha-based Discovery Learning model is more effective in enhancing students' scientific literacy and science learning outcomes.

Abstract

Meningioma is the most common type of benign brain tumor in adults and mostly originates from the meningeal layer of the brain and spinal cord. The prevalence of meningioma in the world is estimated to be about 24-30% of intracranial primary brain tumors. This tumor is classified into three groups based on grade, grade I (benign), grade II (atypical), and grade III (anaplastic). The S100 protein is not specific to meningiomas but some studies have shown that the expression of S100 protein is stronger in grade I meningiomas than in grade II and III meningiomas. Based on these findings, the authors are interested in analyzing whether there is a relationship between S100 expression and meningioma grading. The determination of S100 protein expression is very necessary as a reference in determining the prognosis and selection of the best therapy for patients. This research was carried out in the period from January 2021 to December 2021. 9 samples were included in this study according to the inclusion and exclusion criteria. The data was analyzed using SPSS version 26. The results of this study: A normality test was carried out with the Shapiro Wilk test and a value of p=0.34 (CI 95%) was obtained using Spearman analysis.

Abstract

Mangroves are vital coastal ecosystems that thrive in tidal environments and play a crucial role in biodiversity and shoreline protection. This study aims to assess the vegetation density of the Langsa City Mangrove Forest using the Normalized Difference Vegetation Index (NDVI) derived from Sentinel-2A satellite imagery and analyzed through Geographic Information System (GIS) tools, particularly ArcGIS. NDVI values were categorized into four classes: very low (-0.15–0.34), low (0.35–0.48), medium (0.49–0.61), and high (0.62–0.83). The spatial analysis revealed that 57.2% of the area (approx. 128.5 ha) exhibited high vegetation density, while 24.6% (55.2 ha) showed medium density, and 13.3% (29.9 ha) had low vegetation. Approximately 4.9% (11.0 ha) of the area was classified as very low density, indicating regions with potential for ecological rehabilitation. These findings demonstrate that NDVI is an effective and reliable indicator for monitoring mangrove vegetation health. Routine application of NDVI analysis is essential for supporting sustainable management strategies and long-term conservation planning in coastal forest ecosystems..

Abstract

Polystyrene (PS) is one of the most abundant microplastics in freshwater and can accumulate in fish tissues. This study investigated the effect of PS microplastic exposure in rearing water on the abundance of microplastics in muscle, and the diameter and area of myofibers in Mutiara catfish (Clarias gariepinus). A total of 120 fish were exposed to PS microplastics at concentrations of 0, 1, 10, and 100 mg/L for 28 days. Muscle samples from the right abdomen were processed using the paraffin method and stained with hematoxylin-eosin. Microplastics were extracted using 10% KOH and observed under a stereo microscope. Myofiber diameter and area were measured with Image Raster software. Data were analyzed using the Kruskal-Wallis test. Results showed significant differences among treatments (P<0.05) for all parameters. The control group had the lowest microplastic abundance and the largest myofiber size, while the highest accumulation occurred at 100 mg/L, and the smallest myofiber diameter and area were found at 10 mg/L. Exposure to PS microplastics leads to accumulation in muscle tissue and a reduction in myofiber dimensions. These findings highlight the potential adverse impacts of microplastics on fish health and underline the importance of further studies regarding ecological and human health implications.
