Abstract

In science learning, students' higher-order thinking skills (HOTS) and scientific attitudes are still low. Problems become increasingly complex when the COVID-19 pandemic minimally transforms students' interactions with their community environment. Innovation is needed to obtain an experimental model integrated with the Arduino Internet of Things to enhance HOTS and scientific attitudes. This research aims to obtain a valid and practical Arduino-based experiment model and its effect on HOTS and scientific attitudes. This research and development refers to Borg and Gall consisting of research and collecting of information, planning, initial product development, initial testing, main product revision, main field testing, operational product revision, operational field testing, final product revision, and dissemination. The research subjects involved were physics lecturers, education practitioners, and physics education students in West Kalimantan, Indonesia. Enhancing HOTS after implementing an experiment is calculated using the Multivariate Analysis of Variance. The arduino based experiments model has proven feasible, practical, and effectively applied to improve students' HOTS and scientific attitudes. The results become an innovative alternative laboratory work model to be used as a policy recommendation in higher education.

Abstract

Extreme climate change poses a serious threat to global food security, particularly for rice, which is widely cultivated in tropical regions. Research on adaptive rice varieties and adaptation strategies is becoming increasingly important in responding to this challenge. This study aims to map developments, thematic trends, key actors, and collaborations in research on adaptive rice varieties to climate change, using a bibliometric approach. Data were obtained from the Scopus database for the period 2015–2025 using keywords related to “rice” and “climate adaptation/resilience.” The analysis was conducted using VOSviewer software for three main types of analysis: co-authorship, co-occurrence of keywords, and citation analysis. It was found that publications in this field continue to increase, with the largest contributions coming from China, India, and the United States. Dominant topics include climate-smart agriculture, genetic regulation, and biodiversity. The most prolific authors are Jat M.L., Hasegawa T., and Pan G. Citation analysis indicates a limited amount of highly influential literature, while collaboration networks between countries remain fragmented. The results of this study provide a comprehensive overview of the scientific landscape of adaptive rice research and climate strategies. These findings can be used to strengthen global collaboration, guide future research agendas, and support sustainable agricultural adaptation policies.

Abstract

Changes in river systems can significantly impact communities, particularly through property and infrastructure losses. This study investigates the fluvial landscape changes of the Bone River and their socio-economic implications in the Gorontalo region from a spatial perspective. The research employs multi-temporal Landsat satellite imagery from the Google Earth Engine platform to analyze environmental dynamics in the study area over the period 1995–2025. The imagery dataset includes Landsat 5 TM (May 5), Landsat 7 ETM+ (February 17), Landsat 8 OLI/TRS (October 19), and Landsat 9 (May 31). The results indicate notable changes in the river’s course. Evidence of erosion and sediment deposition was identified along the Bone River banks. The patterns reveal a tendency toward lateral migration of the river channel, horizontal shifts, and narrowing of downstream segments. Several natural cut-off points have formed, along with shifts in the main channel in the upstream and midstream segments during the 1995–2025 period. The lateral migration of the river channel reached up to 1.2 km northeastward (N60°E), primarily driven by anthropogenic activities such as traditional sand mining along the western banks and the conversion of riparian land into residential areas. From a socio-economic perspective, these river morphological changes pose potential threats to riverside infrastructure and may trigger land-use conflicts, particularly in areas with active sand mining operations

Abstract

This study aims to analyze the form of partnership implementation between turnip farmers and PT VAI, examine the benefits of this form of partnership for turnip farmers, and analyze turnip farming income. This study was conducted in Purba District, Simalungun Regency. Farmers in Nagori Pamatang Purba were designated as sample villages from the population that became research respondents. The sampling technique and population in this study used Purposive Sampling and Snowball techniques. The data analysis method used descriptive analysis of PT VAI's contract with partner farmers, farm income analysis, and R/C Ratio. The results of the study indicate that the form of partnership between PT VAI and turnip farmers in Purba District is a subcontract form. Where farmers and PT VAI have a contract regarding seeds, production prices and product quality. The benefits that are definitely obtained by farmers as partners include being able to help in procuring seeds. Farmers get convenience for seeds because they do not have to do their own seeding, thereby reducing the risk of failure because the seeds are ready to plant. The benefits of marketing guarantees provide a guarantee that the resulting product will be immediately sellable. One hundred percent of turnip farmer respondents answered that they received benefits in marketing convenience. This aligns with the initial rationale and hope for joining, which is that farmers won't have to search for markets to sell their products. Marketing guarantees can also motivate farmers to produce according to PT VAI's criteria so their products are accepted. Radish farming in Pematang Purba Village generates substantial income and is considered viable, as the R/C ratio analysis shows a value of 3.01, meaning that for every Rp 1.00 spent, a return of Rp 3.01 is generated.

Abstract

Sepsis is a serious complication that remains a leading cause of death worldwide, especially among young children and the elderly. Delayed diagnosis remains a major challenge, highlighting the need to develop accurate diagnostic modalities, including inflammatory markers derived from routine blood counts. This study aimed to describe the profile of inflammatory markers in sepsis patients at Rumah Sakit Umum Royal Prima Medan in 2024. This observational study employed a cross-sectional design, analyzing 81 medical records of sepsis patients from Royal Prima General Hospital in 2024, selected using simple random sampling. The variables measured included socio-demographic characteristics (age and sex), leukocyte profile (total leukocyte count, eosinophils, basophils, neutrophils, lymphocytes, and monocytes), and inflammatory indices (NLR, PLR, PNR, LMR, and NLPR). Most sepsis patients were male (50.6%) in the early elderly age group (33.3%), with median leukocyte counts of 17,350 cells/µL, neutrophils at 14,660 cells/µL, and lymphocytes at 1,279 cells/µL. The inflammatory marker indices showed trends of NLR 13.21, PLR 290.74, LMR 1.30, PNR 21.50, and NLPR 0.004. These results support the potential of routine blood inflammatory markers as indicators for sepsis progression.

Abstract

Learning in elementary schools is still dominated by the expository method, in which teachers explain while students passively listen, take notes, and complete assignments. This teacher-centered approach restricts the development of students’ critical thinking skills. This study aims to examine the effectiveness of the RADEC (Read, Answer, Discuss, Explain, Create) learning model in improving the critical thinking skills of fourth-grade students in the science subject at SDN 31 Negeri Katon Pesawaran. The study employed a quasi-experimental design with a non-equivalent control group. The sample consisted of 37 students, with 17 students in the control class applying the Problem-Based Learning (PBL) model and 20 students in the experimental class using the RADEC model. The research instrument was a critical thinking skills test in the form of pretest and post-test, consisting of five essay questions. Data analysis included prerequisite tests (normality and homogeneity) and an independent sample t-test. The results indicated a significance value of p = 0.000, which is smaller than 0.05 (p < 0.05), suggesting a significant difference between the two groups. These findings demonstrate that the RADEC model is more effective in enhancing students’ critical thinking skills compared to the PBL model.

Abstract

Network Real-Time Kinematic (N-RTK) positioning has become a fundamental tool in high-precision surveying. However, its accuracy is significantly affected by operational factors, such as baseline length and telecommunication network quality. This research aims to quantify the influence of these two factors on the geometric accuracy of the N-RTK system. Data was collected in a tropical peatland environment in Indonesia. Out of 661 test points, 495 were successfully measured using the N-RTK system with a geodetic GPS. At the other 166 points, however, limited GSM signal coverage in the field necessitated the use of a handheld GPS as an alternative solution to ensure the completeness of the spatial data. The results show that N-RTK accuracy decreases significantly with an increase in baseline length and a decrease in cellular network quality (4G to 3G). The 4G network provides higher accuracy, with a Circular Error 90% (CE90) value of 0.359 m at a 10-20 km baseline distance. At the same distance, the 3G network yields a CE90 of 0.472 m. An increase in distance up to 40-50 km further reduces accuracy, but the resulting accuracy still meets the standard for 1:2500 scale detailed maps. On the other hand, measurements using a handheld GPS yield a CE90 of 5.95 m, which is significantly lower and only suitable for general-scale mapping (1:25,000). This study underscores the importance of cellular network quality and optimal baseline planning to achieve maximum accuracy in N-RTK surveys, as well as highlights the need for alternative solutions in areas with signal limitations.

Abstract

The local wisdom of the indigenous people of the Byak tribe of Kampung Yendidori in utilizing the leaves of red hibiscus (the local name of the leaves "Penbrike") as an herb for mothers after childbirth shows rich empirical knowledge and is relevant to modern chemical concepts. This research aims to integrate an ethnographic perspective based on a mental model in describing the cultural significance of this practice and explaining the content of active compounds in these plants through macroscopic, submicroscopic, and symbolic level approaches. This type of research is qualitative with an ethnographic approach based on mental models. The results obtained show the sacredness of the use of "Penbrike" leaves. The community believes that treatment is effective if it is carried out by the clan or the person appointed to inherit its use. The results of a literature review show that the main content in its leaves is alkaloids, tannins, flavonoids, steroids, saponins, phenols, proanthocyanidins. The active compounds in this plant function as powerful antioxidants that help reduce oxidative stress and postpartum inflammation, some accelerate hemostasis and wound recovery, and some provide vasoconstriction and protein binding effects and help stop bleeding. However, based on the results of other literature reviews, it was found that hibiscus leaves contain anti-fertility compounds, so further research is needed. These studies can serve as a basis for the development of ethnoscience-based chemistry learning models and further research on ethnopharmaceuticals.

Abstract

This study aims to analyze in depth the relationship between the education level of women who will become or have become mothers and their obligations and responsibilities to care for their children. This study uses qualitative methods with a phenomenological approach. Data collection was conducted through observation, interviews, and documentation. In-depth interviews were conducted with mothers who were marginalized or had low educational levels, only graduated from elementary school or even never attended school, as well as with local community leaders and religious leaders. The results of this study conclude that education is a very important factor for a woman as it provides knowledge and skills to care for her children after becoming mothers. Mothers with low education, or even those who did not have the opportunity to receive basic education, tend to be ignorant and indifferent to child development, thus allowing their children to grow and develop naturally, with a permissive parenting style. In an effort to prepare a quality generation in the future, the government and related parties need to fight for equitable access for women to obtain education, so that they will be able to independently raise their families and educate their children.
