MORPHOLOGICAL CHARACTERIZATION OF BRAIN TUMOR TISSUE IN MRI IMAGES USING CNN AND TRANSFER LEARNING
type: item
description: This study evaluates the role of computational pattern recognition as an observational method for analyzing morphological characteristics of brain tumor tissue in MRI data. A total of 6,056 labeled MRI images, including glioma, meningioma, and pituitary tumor cases, were examined. The images were standardized to maintain uniform structural representation and processed using three convolutional-based architectures: a baseline CNN, MobileNetV2, and EfficientNet-B0. Model performance was assessed using accuracy, precision, recall, F1-score, AUC-ROC, and a confusion matrix. The findings show variation in identification performance across tumor categories, with pituitary tumors consistently recognized, while misclassification predominantly occurred between glioma and meningioma. Models based on transfer learning achieved stronger agreement with the reference labels than the baseline CNN, with MobileNetV2 demonstrating the most stable performance. The recurrence of similar misclassification patterns across models suggests the presence of shared morphological characteristics in MRI representations of certain tumor types. Overall, the results support the use of computational image analysis as a structured observational framework that enables consistent evaluation of brain tumor tissue morphology in MRI, providing complementary insights for biological interpretation.

INFLUENCE OF LACTATION STATUS ON DAILY BEHAVIOUR OF ADULT FEMALE LONG-TAILED MACAQUES (Macaca fascicularis) IN AN EX-SITU BREEDING COLONY
type: item
description: This study aimed to analyse the influence of lactation status on the daily behaviour of adult female M. fascicularis in a breeding colony at CV. INQUATEX, Bogor, Indonesia. To achieve this, ten adult females, five lactating and five non-lactating, were observed using the scan sampling method after a habituation period. Observations were conducted twice daily, in the morning (7–9 a.m) and the afternoon (2-4 p.m.), at 5-minute intervals for 14 consecutive days. During these sessions, behavioural categories recorded included feeding, locomotion, resting, grooming, playing, sexual behaviour, human interaction, aggression, vocalisation, and maternal care. Subsequently, behavioural data were expressed as percentages and analysed using the Mann–Whitney U test. The results showed that non-lactating females exhibited higher proportions of feeding, locomotion, and grooming behaviours, whereas lactating females spent more time resting and performing maternal care. Furthermore, statistical analysis revealed significant differences in locomotion (p < 0.01), sexual behaviour (p < 0.05), and maternal care (p < 0.01) between lactating and non-lactating females. Taken together, these findings indicate that lactation status influences behavioural allocation in adult female M. fascicularis. Therefore, reproductive status should be considered in captive management strategies to support animal welfare and enhance breeding success in ex situ conservation programs

EFFECTS OF PRETREATMENT METHODS ON THE LIGNOCELLULOSIC COMPOSITION OF SALACCA MIDRIBS
type: item
description: This study aims to determine the effect of pretreatment on hemicellulose, cellulose, and lignin content of Salacca midrib. Unlike previous studies, this study was designed to evaluate the effects of single-, double-, and triple-stage pretreatments on the sallaca midrib. The study was also designed to evaluate the differences in the physical and biological pretreatment methods. The pretreatments applied consist of physical, chemical, biological, physicochemical, chemical-biological, physical-biological, and physicochemical-biological pretreatments. Physical pretreatment is carried out in an autoclave at 121 °C, chemical pretreatment using Sodium Hydroxide (NaOH) 4%, and biological pretreatment using Debaryomyces hansenii. Based on the ANOVA test, the various pretreatment methods have a significant effect on lignocellulose content. The highest hemicellulose content was the chemical pretreatment at 34.13%, the cellulose content was the chemical pretreatment at 40.85%, and the highest lignin reduction was the physical-chemical-biological at 27.15%

TESTING OF DEXAMETHASONE TOXICITY TO CARDIOMETABOLIC AND MALFORMATION OF ZEBRAFISH (Danio rerio Hamilton, 1882) LARVAE
type: item
description: This study aims to evaluate the toxicity effects of dexamethasone on survival, hatching, cardiometabolic function, and the emergence of malformations in zebrafish larvae (Danio rerio), a vertebrate model organism. The study was conducted during the embryonic to early larval phase (0 – 96 hpf) using an in vivo experimental design with complete randomization, following the Zebrafish Embryo Toxicity Test (ZFET) approach, in accordance with OECD 236 guidelines. Zebrafish embryos were exposed to varying concentrations of dexamethasone (0.5,1, 3, and 7 ppm). The parameters observed included survival rate, hatching rate, cardiometabolic function, and changes in larval morphology. Data were analyzed using normality and homogeneity tests, followed by One-Way ANOVA with LSD post hoc tests and Two-Way ANOVA. The results showed that exposure to dexamethasone did not cause lethal toxicity in zebrafish larvae up to 96 hpf (P = 0.949), but significantly inhibited hatching at 48 hpf (P = 0.007) and 72 hpf (P = 0.032). Dexamethasone was also significant in lowering the larvae’s heart rate in a dose- and time-dependent manner (P < 0.001). The two-way ANOVA results further indicated that dose, exposure time, and their interaction had significant effects on cardiometabolic function (P < 0.001).

PROFILE OF CLIMATE CHANGE LITERACY AND SUSTAINABILITY AWARENESS ON GLOBAL WARMING MATERIAL
type: item
description: This study critically maps the climate change literacy (CCL) and sustainability awareness (SA) profiles of eighth-grade students at SMPN Satap 5 Hanau regarding global warming material. Employing a quantitative descriptive approach as an initial R&D needs assessment, the study uses cognitive tests, attitude questionnaires, and behavioral observations. Results reveal a pronounced behavioral gap: students excel in basic knowledge (average 86.5%) and show strong environmental concern (83.2%), but are severely deficient in higher-order thinking skills for mitigation and adaptation (0%). Actual sustainability actions, such as energy conservation, remain low (30.8%–48.1%). Clearly, learning remains confined to knowledge transfer. This evidence underscores the urgent need for action- and project-based learning models to close the gap between students' knowledge and their capacity for meaningful action

SCREENING OF LDPE PLASTIC-WASTE-DEGRADING BACTERIA USING WINOGRADSKY COLUMN
type: item
description: This study aims to screen Low-Density Polyethylene (LDPE)-degrading bacteria from three highly plastic-contaminated environments: the Jatimalang River stream, Bekonang Market soil, and Joho Village Waste Disposal Site. The research used the Winogradsky column method with two incubation periods: 1 month and 2 months. This research was conducted with 3 repetitions using a descriptive-quantitative data analysis approach, and was a preliminary screening. Observed parameters included the percentage of plastic degradation, biofilm thickness, physical changes in LDPE, and bacterial morphology isolated using Nutrient Agar. The results showed that the highest degradation occurred in the waste-disposal soil (TPS), with values of 34.37% (1 month) and 40.62% (2 months), followed by river soil (22.72% and 27.27%) and market soil (13.63% and 18.18%). Biofilm thickness was also most significant in TPS samples, reaching 0.57 ± 0.01 and 0.91 ± 0.03 μm. Physical changes included yellowish to brownish discoloration, increased roughness, and enhanced elasticity of LDPE. All bacterial isolates exhibited irregular colony forms, lobate margins, flat elevations, and cream-to-yellow pigmentation. Gram staining identified all isolates as Gram-positive bacteria. These findings indicate that plastic-contaminated environments hold strong potential as natural sources of LDPE-degrading bacteria.

PHYTOCHEMICAL SCREENING AND ANTIBACTERIAL ACTIVITY OF SOFT CORAL Nephthea sp. EXTRACT ISOLATED AGAINST Escherichia coli
type: item
description: This study aimed to evaluate the antibacterial potential of Nephthea sp. extract against Escherichia coli and to analyze the phytochemical constituents present in Nephthea sp. using various solvents. The extraction process was carried out using the maceration method with three different solvents: n-hexane, ethyl acetate, and methanol. The resulting extracts were analyzed through phytochemical screening and antibacterial activity assays. The results showed that Nephthea sp. extract contained several classes of bioactive metabolites, including alkaloids, flavonoids, triterpenoids, steroids, tannins, and saponins. Antibacterial testing demonstrated that the ethyl acetate extract produced the largest inhibition zone, measuring 3.16 mm. Based on the ANOVA test results, the 25% concentration showed a significant effect on the inhibition zone. Based on phytochemical analysis, the ethyl acetate extract contained triterpenoid compounds, whereas the other solvents did not

VISUAL REPRESENTATIONS ANALYSIS OF SENIOR HIGH SCHOOL BIOLOGY TEXTBOOKS ABOUT THE HUMAN MOVEMENT SYSTEM
type: item
description: This study aims to identify the proportions and types of visual representations in Grade XI Biology textbooks, specifically on the topic of the Human Locomotion System. Visual content in Biology textbooks plays a crucial role in facilitating students’ understanding of biological concepts; however, previous studies have shown that such content remains limited in depth and rarely connects biological material to real-life contexts. The objective of this research was to examine the functions and forms of visual representations in selected textbooks, and to evaluate their alignment with principles of effective visual representation. Employing a qualitative content analysis approach, four textbooks were analyzed using a classification framework that classified the visual representations by their function (decorative, illustrative, explanatory, complementary) and by their form (e.g. illustrations, diagrams, tables, maps). The results revealed that visual representations were predominantly illustrative in both function and form across all Biology textbook samples. Among the samples, the YT textbook demonstrated the highest quantity and diversity of visual content, while KM had the fewest. These findings suggest that the textbooks have not fully adhered to the principles of effective visual representation, which may limiting students’ understanding of complex biological concepts. It is recommended that future editions increase both the quantity and variation of visual content to enhance pedagogical effectiveness and promote deeper learning.

THE IMPACT OF INADEQUATE LABORATORY PERSONNEL (LABORATORY HEADS, TECHNICIANS, AND ASSISTANTS) ON BIOLOGY PRACTICUM IMPLEMENTATION
type: item
description: This study aims to examine the limitations of human resources (HR) in school laboratories and their impact on the implementation of biology practicum activities at the senior high school level. A descriptive qualitative method was employed in Kotagede District, Yogyakarta, using purposive sampling to select two schools with active biology laboratories. Data were collected through in-depth interviews with laboratory personnel and biology teachers to explore the availability, involvement, and roles of laboratory staff in supporting practicum activities. The findings revealed significant differences between the two schools. School A had a complete laboratory staff, including a head of the laboratory and a laboratory assistant, which allowed practicum activities to be conducted in a structured and systematic manner, effectively supporting students' conceptual understanding and scientific understanding. supporting students' conceptual understanding and scientific skills. In contrast, School B lacked laboratory personnel, resulting in all practicum responsibilities being assigned to the biology teacher, which led to suboptimal implementation and limited student learning experiences. Therefore, efforts to increase the availability and competence of laboratory personnel in accordance with national standards are necessary. The presence of professional laboratory staff plays a crucial role in creating effective, meaningful, and skill-oriented biology learning through practicum-based approaches.

POTENTIAL IMPLEMENTATION OF ETHNOSCIENCE-ORIENTED LEARNING ON BIOTECHNOLOGY MATERIAL
type: item
description: There are still many science learning practices that focus on memorization and do not relate the subject matter to real life or the local cultural context of students. Science is often perceived as a difficult and boring subject because it relies heavily on technical terms and abstract material. This study aims to explore the potential implementation of ethnoscience oriented learning in biotechnology material at the junior high school level. Data were collected through interviews with 11 science teachers from Sub Rayon 05 of Grobogan Regency and classroom observations involving 3 peer teachers at SMP Negeri 1 Ngaringan. The interview was conducted using a Google Form-based questionnaire, while observation data were obtained through direct observation using a structured observation sheet. The results showed that teachers had a good understanding of ethnoscience (78.7%), and the potential for implementation was considered very high (84%). However, curriculum development remained the lowest aspect observed (67%). These findings indicate that while the conceptual understanding and enthusiasm of teachers toward ethnoscience are strong, effective implementation requires systemic support, training, and curricular alignment.

IN SILICO ANALYSIS ON BINDING ACTION OF TERPENE NATURAL COMPOUNDS FROM APOCYNACEAE FAMILY AGAINST SHV-1 BETA-LACTAMASE FROM Klebsiella pneumoniae
type: item
description: Antibiotic resistance is a growing threat to public health, particularly with hospital-acquired infections caused by Klebsiella pneumoniae. The limited treatment options for these infections are further complicated by the emergence of antibiotic-resistant strains due to the overuse of antibiotics. This study investigates the potential of Monoterpene Indole Alkaloids (MIAs) derived from six genera within the Apocynaceae family as inhibitors of the beta-lactamase enzyme (bla-SHV-1), which plays a key role in antibiotic resistance in Klebsiella pneumoniae. Using the PyRx program for molecular docking, we assessed the binding affinity and interaction profiles of various MIAs with bla-SHV-1. Our results identified Paucidisine, (-)-19-Oxoisoeburnamine, and Paucidactine A as the most promising candidates, based on their interaction energies and binding modes. Detailed analysis of ligand-protein interactions, including hydrogen bonds and hydrophobic interactions, revealed that these MIAs exhibit higher binding affinity and structural similarity to the native ligand bla-SHV-1. While these findings are promising, it is important to note that they are based on in silico models. Further in vitro and in vivo studies are required to validate the efficacy and safety of these MIAs as potential therapeutic agents. This research marks a significant step towards developing alternative treatment options for antibiotic-resistant Klebsiella infections, potentially improving patient outcomes and addressing the global challenge of antibiotic resistance. In conclusion, our study offers novel insights into the potential use of MIAs as inhibitors of bla-SHV-1, contributing to the ongoing efforts to combat antibiotic resistance. Future research should focus on validating these in silico results through rigorous experimental and clinical studies, considering the ethical implications of introducing new treatments.

BUILDING SUSTAINABILITY AWARENESS: INTEGRATING ESD INTO HUMAN DIGESTIVE SYSTEM EDUCATION
type: item
description: In response to global environmental challenges such as climate change, pollution, and resource depletion, this study aimed to develop and evaluate Education for Sustainable Development (ESD)–oriented science learning materials on the human digestive system to enhance students’ sustainability awareness. Employing a Research and Development (R&D) approach and the ADDIE model, the instructional materials were implemented in a quasi‑experimental design with two eighth‑grade groups at SMP Negeri 2 Tulis during the 2024/2025 odd semester. Sustainability awareness was measured using a 26‑item questionnaire administered as a pretest and posttest. The experimental group, which received the ESD‑oriented intervention, demonstrated a mean pretest score of 70.55 and a posttest score of 92.06 (mean N‑Gain = 0.63). The experimental group showed significantly higher gains in both sustainability awareness—especially in emotional engagement—compared to the control group. These outcomes suggest that integrating ESD into science learning not only improves conceptual understanding but also shaping environmentally responsible and reflective students.

type: item
description: Leachate contains TSS (Total Suspended Solid) and TDS (Total Dissolved Solid) which causes turbidity and a blackish brown color in the leachate. One effort that can be made to deal with environmental pollution caused by leachate is phytoremediation. This research aims to determine the effectiveness of water bamboo as a phytoremediation agent for TSS and TDS from landfill leachate. This research is an experimental study with a completely randomized design (CRD) with three treatment levels and three repetitions. The treatments given in this research were three variations of water bamboo, namely P0 : without water bamboo, P1: 750 g water bamboo, and P2: 1.000 g water bamboo. Based on research results, water bamboo is not effective in reducing TSS and TDS. The most optimal percentage reduction in TSS occurred in the P2 on the third day of the study (16.83%). The most optimal percentage reduction in TDS occurred in the P1 on the seventh day of the study (6.56%). The results of research show that phytoremediation can reduce Jatibarang Landfill leachate, especially TSS and TDS levels accumulated by the roots of water bamboo.

UTILIZATION OF LIQUID ORGANIC FERTILIZER TO BREAK SEED DORMANCY AND GROWTH OF SUGAR APPLE (Annona squamosa L.) SAPLINGS
type: item
description: Generative propagation of sugar apple has obstacles caused by the hard seed coat that inhibits the imbibition process and the seeds become dormant. Liquid organic fertilizer (LOF) can be used as a solution to break seed dormancy and the growth of sugar apple (Annona squamosa L.) seedlings. This study is conducted to determine the right concentration and soaking time of LOF, as well as to determine the effect of the interaction between concentration and soaking time of LOF for breaking seed dormancy and growth of sugar apple seedlings. The research is conducted using a randomized complete factorial design with 2 factors, namely LOF concentration (0%, 25%, 50%, 75%, 100%) and soaking time (6, 12, 18, 24 hours). Data are analyzed using ANOVA and DMRT further test at 5% level. The results shows that the LOF concentration, soaking time and the interaction between the combination of LOF concentration and soaking time are not yet obtained to break seed dormancy and the growth of sugar apple seedlings. The use of 25% LOF concentration showed significant differences with other LOF concentration treatments (50, 75, 100%) on growth parameters (plant height, number of leaves and fresh biomass), but not significantly different compared to the control on all germination and growth parameters. Soaking times of 6 hours and 12 hours are not significantly different on all germination and growth parameters, but significantly different from soaking 18 hours and 24 hours on germination parameters (germination percentage and vigor index). The interaction of LOF concentration and soaking time is not significantly different on all germination and growth parameters.

T HELPER 17 (Th17) AND REGULATORY T (Treg) CELLS PROFILE IN TYPE-2 DIABETES MELLITUS (T2DM)
type: item
description: One of metabolic disorder disease is Type 2 Diabetes mellitus (DM), leading to increased glucose, cholesterol, and lipid levels in the blood. Type 2 DM results in insulin resistance within the body. Glycolysis, oxidative phosphorylation, and fatty acid are the three main metabolic pathways which provide energy for T cells. T cells will ploriferate, differentiate and become active into T Helper-17 and T regulator (Treg) cells because of these pathways. The profile of TH-17 cells and Treg cells in type 2 diabetes will be opposite in terms of the number of their populations caused by metabolic disorders in the body. Type 2 diabetes make an immunology response with increasingly number of TH-17 cells, while lack of Treg cells. Many studies have shown that diabetes mellitus as a metabolic disease effect populations of T Helper-17 and regulatory T cells. Glycolysis is the main energy metabolism becomes important factor that stimulate the proliferation and differentiation of Th-17 cells. The energy produced from this metabolism is in the form of ATP, which is the result of glucose synthesis using the Glucose transporter (GLUT). Glucose transporters (GLUT-1) are most dominantly expressed by Th-17 cells and Treg cells. Metabolic disorder causes an imbalance in the population of TH-17 cells with Treg cells. This review will explain the profiles of TH-17 and regulatory T cells in Diabetes mellitus and their relationship with body metabolism disease.

ECOLOGICAL STUDY OF THE SUNDA PANGOLIN (MANIS JAVANICA DESMAREST, 1822) IN THE NATURE TOURISM PARK OF BUKIT TANGKILING, CENTRAL KALIMANTAN, INDONESIA
type: item
description: The Sunda pangolin, also known as Manis javanica, is a vulnerable mammal that can be found in Java, Sumatra, and Kalimantan. Unfortunately, due to hunting, poaching, land changes, and forest fires, particularly in Kalimantan, this species is now categorized as endangered on the IUCN Red List. To support conservation efforts and sustainability of the Sunda pangolin, it is crucial to gather more evidence about its ecological study and habitat. Therefore, this study aimed to determine the characteristics of the habitat and distribution of the Sunda pangolin in the Bukit Tangkiling Nature Park, Central Kalimantan. We surveyed between February and June 2022 using a Visual Encounter Survey (VES) combined with burrow count methods and camera traps. The survey included vegetation, potential nest and prey, and abiotic factors for the Sunda pangolin. We found a total of two individuals using a camera trap in plot 1 and direct observation in plot 3. Additionally, we located five potential Sunda pangolin nests. According to the distribution map, the Sunda pangolin can be found in hilly and valley areas, with an estimated population of 7.14 individuals/Ha. Vegetation analysis revealed an importance value index (IVI) of 148.84% for Acacia mangium. Based on PCA results, the abiotic factors of air and soil humidity support the existence of the Sunda pangolin and its nests. We also identified eight species of Hymenoptera and one species of Isoptera, which are potential food sources for the Sunda pangolin. Overall, this study provides essential information to support conservation efforts and sustainability of the Sunda pangolin in Kalimantan.

type: item
description: Eco-enzyme is a mixture of organic fruit peel waste fermented with a mixture of brown sugar and water. It can be used as organic fertilizer. The aim of the research is to find out how eco-enzymes help literacy and numeracy in the growth of mustard greens (Brassica chinensis). Eco-enzymes are made with a composition of 10:3:1: 10 liters of water, 3 kilograms of vegetable waste or fruit peels, and 1 kilogram of brown sugar. In a fifteen liter plastic container, dissolve brown sugar in water. Then, add the skins and vegetable waste, and cover tightly and ferment for three months. Mustard seeds are sown and planted in polybags. Watering is done with water every day; watering with eco-enzyme solution is carried out once every three days. The amount of eco-enzyme used is 0 ml, 7.5 ml, 15 ml, and 22.5 ml in one liter of water. The parameters measured for mustard plants are height (cm) and number of leaves (sheets). The research results showed that the application of eco-enzymes as organic fertilizer at a concentration of 7.5 ml had a positive impact on the height and number of leaves of mustard plants, but had a negative impact on eco-enzyme concentrations of 15 ml and 22.5 ml. Thus, it can be concluded that administering eco-enzymes as organic fertilizer provides the most effective effect at the level of 7.5 ml
