Abstract

Hypertension is a multifactorial chronic disease and a leading cause of global morbidity and mortality, with a high prevalence in Indonesia. Irrational pharmacotherapy can reduce therapeutic effectiveness, increase the risk of adverse drug reactions, and exacerbate the economic burden on the healthcare system. This study aims to evaluate the rationality of hypertension treatment in Indonesia based on the Joint National Committee 7 (JNC 7) and 8 (JNC 8) therapy standards. A literature review was conducted on research articles accessed via Google Scholar, published between 2015 and 2025. Of the 675 identified articles, 10 met the inclusion criteria, which required that the articles contain percentage data on the rationality of hypertension treatment and use JNC 7 or JNC 8 as a reference. The results indicate that the appropriate indication aspect achieved the highest level of adherence, with 8 out of 10 studies (80%) reporting 100% compliance. The aspect of appropriate dosage was also high, exceeding 97% in 9 studies (90%). However, the appropriate drug selection rate showed wide variation, ranging from 48.65% to 100%. This inconsistency was primarily attributed to the prevalent use of monotherapy in stage 2 hypertension patients, for whom combination therapy is recommended. Calcium Channel Blockers (CCBs), particularly amlodipine, were the most frequently prescribed antihypertensive class, dominating the prescribing patterns in 8 out of the 10 studies (80%). In conclusion, hypertension treatment in Indonesia demonstrates a high degree of rationality concerning indication, drug selection, and dosage appropriateness, aligning with JNC standards to achieve optimal blood pressure control.

Abstract

The issue of disposable diaper waste is a significant environmental challenge because it is difficult to decompose, taking between 250 and 500 years, and leads to widespread pollution. The rising volume of diaper waste and the suboptimal disposal of rice wash water (air tajin) require innovative solutions. This research offers a novel approach by integrating the water retention capacity of diaper hydrogel with the nutritional benefits of rice wash water into a single Liquid Organic Fertilizer (LOF) formulation. A nutritional hydrogel derived from used diapers can absorb baby urine, which contains ammonia (approximately 60%) and urea (approximately 35%), both of which are essential nutrients for plants. DHT Fertilizer is created by extracting hydrogel from cleaned, used diapers. The hydrogel is heated to 50 °C for 60 minutes, then mixed with 60 mL of rice wash water. This study aims to repurpose these waste materials into "DHT Fertilizer" and test its effectiveness on the growth of bird's eye chili (Capsicum frutescens). Experimental Design: This quantitative experiment involved one control plant and one treatment plant, each with a single replication, and was observed over a two-week period. The independent variable was the dosage of DHT Fertilizer, and the dependent variable was the growth of the chili plants. The fertilizer was applied by spraying the plants twice daily, in the morning and evening. The results show that DHT Fertilizer significantly and rapidly increases the growth of bird's eye chili compared to the control plant. This accelerated growth is driven by the ammonia and urea content, while the vitamin B and E components from the rice wash water improve the plant’s resistance to weather changes. Additionally, the hydrogel component helps the plant absorb and store water efficiently. DHT Fertilizer serves as an eco-friendly, efficient, and easy-to-use solution to overcome growth vulnerabilities in chili plants.

Abstract

Students in the 21st century are required to develop advanced thinking skills, especially critical thinking skills, which are essential for dealing with technological advances and scientific developments. Results from international studies indicate that Indonesian students, particularly at the junior high school level, still have relatively low critical thinking skills. This study aims to determine the extent to which guided inquiry approaches can strengthen critical thinking skills among junior high school students. The method used in this study was a Systematic Literature Review (SLR) that adopted the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach. The articles analyzed are national and international publications from 2015 to 2025 that are relevant to the topics of Guided Inquiry and critical thinking skills. The synthesis results indicate that guided learning models are consistently effective at enhancing critical thinking skills, particularly in analysis, evaluation, and conclusion. This model requires students to be active in scientific investigation, engage in reflective thinking, and connect concepts to real-life contexts. The integration of the STEM approach, digital learning media, and local contexts further strengthens its effectiveness in shaping scientific and collaborative mindsets. The uniqueness of this study is evident in its comprehensive synthesis of the application of guided learning approaches in the 21st-century context, which emphasizes the integration of technology and contextual learning as a strategy for enhancing critical thinking. This study concludes that the Guided Inquiry Learning Model is an adaptive, innovative, and relevant learning model for strengthening critical thinking skills in the modern era, especially at the junior high school level.

Abstract

The integration of digital-based Problem-Based Learning (PBL) is increasingly important to support learning that demands critical thinking and collaboration skills in the technological era. This approach allows the exploration and investigation process to be carried out in a more interactive, flexible, and student-centered manner, making it relevant for improving the quality of 21st-century learning. This study aims to explore the forms of digital PBL implementation and its impact on student competencies through a systematic review. The method used is a Systematic Literature Review (SLR) with article searches in Publish or Perish version 8 and Google Scholar, using the keywords “Problem-Based Learning,” “digital learning,” “critical thinking,” and “collaboration” for the period 2020-2025. The selection process followed PRISMA 2020, resulting in 15 articles meeting the inclusion criteria from the initial 200 articles. Data analysis was conducted using a thematic descriptive approach to identify patterns in findings across three main themes: forms of digital PBL implementation, its effects on critical thinking and collaboration skills, and implementation challenges. The results of the study show that technologies such as Nearpod, Padlet, blended learning, mobile learning, and interactive media play an important role in enriching the PBL stages, while also improving critical thinking and collaboration skills by supporting information access and more dynamic learning interactions. However, implementing digital PBL faces obstacles, including limited facilities, teacher readiness, and variations in students' digital literacy. This study confirms that digital PBL has great potential to improve learning quality, with implications for facilities, teacher training, and the strengthening of digital competencies. Further studies are recommended to develop a more adaptive digital PBL integration model and media innovations that are appropriate for future learning needs.

Abstract

The low level of students' conceptual understanding in science learning remains a primary issue, as instructional activities often emphasize rote memorization and fail to optimally utilize digital media to support meaningful learning. This study aims to examine the role of digital media across the stages of the Discovery Learning model, identify the most effective types of digital media, and determine the characteristics of science topics that require technological support. The research method employed is a Systematic Literature Review (SLR) of 15 relevant articles published between 2020 and 2025. Data were analyzed thematically by grouping findings based on the role of digital media in the Discovery Learning stages, media types, science topics, as well as supporting and inhibiting factors in implementation. The results indicate that digital media such as PhET simulations, animated videos, interactive flipbooks, and augmented reality significantly enhance students' conceptual understanding by providing visual and interactive representations. These media are most effective for abstract topics such as energy, the solar system, and the digestive system. However, their implementation faces challenges, including limited school facilities, low digital literacy among teachers and students, and insufficient preparation time. The integration of digital media within the Discovery Learning model proves effective in concretizing abstract science concepts, with the novelty of this study lying in its comprehensive mapping of the relationships between media types, learning stages, and topic characteristics. Practically, these findings can serve as a guide for educators in selecting and designing digital media for more innovative instruction. Academically, this study encourages further research to address implementation challenges and to explore more personalized and adaptive technology integration for supporting quality science education.

Abstract

This research is motivated by the fact that students frequently experience misconceptions, particularly in distinguishing between temperature and heat, understanding the direction of heat transfer, and analyzing the relationship between heat and phase changes. This study aims to analyze the effect of using the Hydrostatics and Heat Kit on senior high school students’ conceptual change in the topic of heat. The use of the Hydrostatics and Heat Kit in heat instruction is expected to facilitate students’ conceptual understanding through concrete and direct experimental activities. This study employed an experimental method with a one-group pretest–posttest design conducted at SMA Negeri 1 Bolangitang. The research subjects consisted of two classes: an experimental class and a replication class, each with 30 students. A Three-Tier Diagnostic Test was used as the research instrument to identify students’ conceptual status, which was classified into Guessing (MB), Lack of Conceptual Understanding (TPK), Misconception (M), and Scientific Understanding (PK). Data were analyzed using descriptive quantitative analysis by comparing pretest and posttest results to identify patterns of students’ conceptual change. These patterns were represented by red arrows (↑) indicating improvement from misconception to scientific understanding, blue arrows (↓) indicating a decline in conceptual understanding, and yellow circles (O) indicating no conceptual change. The results showed that students in both classes experienced conceptual changes toward more scientific understanding, as indicated by the dominance of red arrows (↑). The most significant improvements occurred in differentiating between temperature and heat and in analyzing the relationship between heat and temperature changes during phase transitions. These findings support the Constructivism Conceptual Change theory, which emphasizes learning as a process of reconstructing initial conceptions into more accurate scientific concepts. Overall, the use of the Hydrostatics and Heat Kit within an Inquiry-Based Learning framework was effective in improving students’ conceptual understanding and reducing misconceptions about heat.

Abstract

Conflict between local communities and wildlife in the buffer villages surrounding Bogani Nani Wartabone National Park (TNBNW) continues to rise due to increasing human pressure on forest ecosystems. This study aims to identify the types of conflict, the wildlife species involved, and community responses to these disturbances. Data were collected through interviews with 30 respondents in East Suwawa and West Dumoga Subdistricts. Results show that most conflicts (90%) are triggered by wildlife perceived as agricultural pests, while 10% are caused by animals entering residential areas. Key species involved include the crested black macaque (Macaca nigrescens), Sulawesi wild boar (Sus celebensis), snakes, lowland anoa (Bubalus depressicornis), and various bird species. Reported disturbances range from crop damage and wildlife presence in farmlands to potential threats to human safety. Most community mitigation efforts are non-lethal, such as installing nets, using spiritus as a repellent, guarding fields with dogs, and setting simple traps. However, hunting still occurs in some areas for crop protection or economic purposes. Habitat loss from encroachment, logging, and land clearing exacerbates conflict by pushing wildlife out of forests into human landscapes. Overall, these findings demonstrate that human–wildlife conflict leads not only to economic losses but also threatens the survival of protected species such as Macaca nigrescens (VU), Sus celebensis (NT), and Bubalus depressicornis (EN). This study demonstrates scientific novelty by presenting an integrated empirical analysis of the forms of human–wildlife conflict, the composition of species involved, and community response patterns in buffer villages surrounding Bogani Nani Wartabone National Park that have not previously been systematically documented, and provides practical contributions by offering an evidence-based foundation for the development of adaptive, non-lethal, and community-based conflict mitigation strategies to support conservation area management and the protection of threatened species.

Abstract

Low learning outcomes, especially in IPAS subjects, are often caused by students becoming passive and disengaged in class when learning is dominated by lecture methods (teacher-centered). Thus, the purpose of this study is to investigate how well the Teams Games Tournament (TGT) model, combined with question-ball media, affects fourth-grade students' learning outcomes. In this study, a quantitative, one-group pretest-posttest design was used, with 24 students from SDN 03 Sidigede as the research subjects. The instrument in this study was a validated learning outcome test, and the data analysis involved normality testing and N-Gain analysis using IBM SPSS version 25. According to the analysis, using the TGT model with question-ball media improved student learning outcomes. This is indicated by the N-Gain values in the moderate improvement category for the concept understanding and skills processes, which are 0.57 and 0.54, respectively. These findings indicate that implementing the TGT model with the help of question ball media not only improves learning outcomes but also encourages active student participation in learning, strengthens learning motivation, and helps students understand IPAS concepts more contextually through game activities and group work.

Abstract

Motivation plays a crucial role in the integrated science learning process. Low learning motivation is often not due to limited ability but rather to a lack of encouragement. In integrated science learning, the human digestive system presents complex material that is difficult to visualize, resulting in decreased student learning motivation. This research aims to develop the Uno Dare Card learning media, which is feasible (valid, practical, and effective), to enhance students' learning motivation in the human digestive system material. The research method employed the ADDIE development model with 29 eighth-grade students from class VIII I of SMP Negeri 1 Martapura Kota as research subjects. The instruments used to collect data included test and non-test instruments. The research results show that the Uno Dare Card learning media is highly valid across content, presentation, language, and media feasibility, with an overall score of 0.943 in the highly valid category. The Uno Dare Card is also highly practical, and the Uno Dare Card learning media has been proven effective in enhancing learning motivation, with N-gain values in the high category. The Uno Dare Card learning media is valid, practical, and effective for teaching material on the human digestive system and for enhancing students' motivation to learn.

Abstract

Iron (Fe) contamination in Indonesian waters frequently exceeds the drinking water quality standard (0.3 mg/L) and poses risks to human health and aquatic ecosystems, highlighting the need for a selective and effective removal method. This study aimed to analyze the effect of solution concentration on the adsorption capacity of an EDTA-based Ion Imprinted Polymer (IIP) for Fe(III) ions. The research employed an experimental design through the synthesis of IIP using the precipitation polymerization method, with methacrylic acid (MAA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the crosslinker, and benzoyl peroxide (BPO) as the initiator. Data were collected through characterization using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy with Energy Dispersive X-ray (SEM-EDX), while Fe(III) concentrations were measured using Atomic Absorption Spectrophotometry (AAS). Fe(NO₃)₃ solutions at concentrations ranging from 5 to 35 ppm were tested at neutral pH. Data analysis was conducted by calculating the adsorption capacity as the difference between the initial and final concentrations. The results showed that increasing the initial concentration increased adsorption capacity until equilibrium was reached, with a maximum of 19.06 mg/g. FTIR analysis confirmed the presence of characteristic functional groups and the removal of Fe–O bonds after extraction, while SEM analysis revealed the formation of specific cavities in the IIP structure. In conclusion, the synthesized IIP demonstrates good selectivity and effectiveness for Fe(III) adsorption from aqueous solutions, indicating its potential application as a selective adsorbent for heavy metal-contaminated water treatment.
