Abstract

Healing of tooth socket wounds after tooth extraction is a complex process involving phases of inflammation, proliferation, and tissue remodeling. Avocado seeds (Persea Americana Mill.) are known to contain bioactive compounds, including flavonoids, saponins, tannins, and triterpenoids, which have the ability to accelerate the wound healing process. This study aims to determine the effectiveness of avocado seed ethanol extract gel on changes in body weight, socket wound diameter, and socket depth after tooth extraction. This study used a laboratory experimental design with a post-test only control group design using male Wistar rats as test animals. The samples were divided into five groups, consisting of a negative control, a positive control (Gengigel), and treatment groups with avocado seed ethanol extract gel at concentrations of 10%, 20%, and 30%. Body weight was measured from day 1 to day 14. The diameter and depth of the socket wound were also measured periodically. Data analysis used the Paired Samples T-Test, Welch ANOVA, and Dunnett T3 Posthoc test in accordance with the results of normality using the Shapiro-Wilk test and data homogeneity using the Levene test. Based on the results of the study, it was found that 10% ethanol extract gel from avocado seeds was most effective in maintaining the stability of the body weight parameters of the test animals, and 30% ethanol extract gel from avocado seeds was most effective in accelerating the reduction in wound diameter and depth, with results comparable to the gold standard (Gengigel). It can be concluded that ethanol extract gel from avocado seeds, especially at a concentration of 30%, is effective in accelerating the healing process of socket wounds after tooth extraction.

Abstract

This study aimed to improve the reading skills of third-grade students at SD Negeri Sonosewu through the application of the Speed-Reading method assisted by audio-visual media. The research was conducted during the first semester of the 2025/2026 academic year using Classroom Action Research (CAR) implemented in two cycles, each consisting of planning, action, observation, and reflection stages, with 27 students as participants. Data were collected through reading skill tests and classroom observations and analyzed using descriptive quantitative and qualitative techniques. The results showed that students' reading skills were initially low, with a pre-cycle average score of 52. After the implementation of the Speed-Reading method in Cycle I, the average score increased to 69, indicating sufficient improvement, although some students still experienced difficulties in understanding texts efficiently. Further improvements were applied in Cycle II, resulting in a significant increase in the average score to 85, which was categorized as very good and exceeded the success indicator of 75%. These findings indicate that the Speed Reading method assisted by audio-visual media is effective in improving the reading skills of third-grade students at SD Negeri Sonosewu.

Abstract

The watershed has a strategic role in maintaining hydrological balance, ecosystem integrity, and community welfare. However, the Rungan watershed is under threat from deforestation and ecosystem damage, therefore a study is needed that considers all related aspects as the basis for making a management strategy for the Rungan watershed. This study aims to find out the priority problems faced by the Watershed Rungan and the aspects of its causes. Furthermore, this research also seeks to formulate priority solutions that can overcome the problems faced by the Rungan watershed. Using qualitative and quantitative approaches, this study applies the Analytical Network Process (ANP) in formulating the priority strategy for the management of the Watershed.  This study found that ecological problems are considered the main problem. Alternative solutions that have been successfully formulated include ecological restoration, economic recovery, and institutional strengthening and coordination between stakeholders. Zoning regulation is a priority for area management and is the main strategy for the management of the Rungan watershed by regulating various programs such as forest rehabilitation, ecotourism, and environmentally friendly land use. For these programs to be carried out in a synergistic manner, it is necessary to coordinate and synergize programs between relevant stakeholders.

Abstract

This study aimed to develop and evaluate an Augmented Reality (AR)-based simulation media for teaching fiber optic splicing in vocational network technology education. Using a Research and Development (R&D) approach with the 4D model (Define, Design, Develop, Disseminate), the product was validated by experts and tested for practicality and effectiveness through a one-group pretest–posttest design. The media obtained high validity scores (Aiken’s V = 0.85 for media and 0.97 for material), was categorized as very practical by teachers (98.31%) and students (89.52%) and showed significant improvement in learning outcomes (N-gain = 0.7115; p < 0.05). Unlike previous AR studies that mainly focus on conceptual science learning, this research integrates procedural vocational skills simulation with mobile-based AR to address limited access to expensive splicing equipment. The findings indicate that AR-based simulation can effectively enhance students’ procedural understanding and support technology-integrated vocational pedagogy

Abstract

In the independent curriculum, differentiated learning is known. Differentiated learning views students differently and dynamically. In this case, teachers view learning from various perspectives. However, this does not mean that differentiated learning is individualized learning. Differentiated learning is a learning approach that adapts learning to the needs of students starting from interests, learning styles, student readiness and other characteristics. In the process, differentiated learning consists of two types, namely differentiation based on learning styles and differentiation based on learning abilities. This study aims to explore differentiated learning related to the research design used, the right learning model, the effect of differentiated learning on students' science learning outcomes and the profile of the use of differentiated learning in science learning at various levels of education. This study is a systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method. Publish or perish was used to collect data from Google Scholar with a span of 2021-2025, 1000 articles were identified and filtered based on criteria, resulting in 15 articles that met the criteria. Research on differentiated learning mostly uses Classroom Action Research (CAR) design. The learning model that is widely used is by combining differentiated learning strategies. Differentiated learning has a positive impact on student learning outcomes and activities. Differentiated learning can be applied at every level of education.

Abstract

This study aims to test the effectiveness of PAsamBa (Acid-Base Learning) learning innovation integrated with ecoprint batik practice in improving conceptual understanding and vocational skills of eleventh-grade students in the Fashion Design expertise program at Vocational High Schools (SMK). The acid-base concept has direct relevance to textile skill processes such as mordanting, color fixation, and pH stability of natural dyes, which are important in sustainable fabric dyeing. The study used a one-group pretest-posttest design involving 73 students from three vocational high schools in Aceh. The instruments included a 20-item acid-base concept understanding test (α = 0.86) and a vocational skills rubric that assessed procedural accuracy, color stability, and ecoprint pattern quality. The results showed a significant increase (t( 72) = 12.86; p < 0.001), with the average score increasing from 43.69 to 80.53 and an N-gain value of 0.67 (medium-high category, approaching high). Students' vocational skills also improved, with an average process score of 3.49 and a product score of 3.41 (scale 4). These results demonstrate that the PAsamBa–Ecoprint approach effectively integrates chemistry learning with contextual textile practices to strengthen students' conceptual understanding and readiness for the creative fashion industry.

Abstract

The Bacillus Calmette-Guerin vaccine did not show consistent results in preventing tuberculosis, with an effectiveness ranging from 0% to 80%. More effective proteins are needed as vaccine candidates to eliminate tuberculosis. Culture filtrate proteins 10-kDa(CFP-10) and Excretory Antigen Target 6-kDa(ESAT-6) demonstrated very strong antigenicity against T and B cells. These proteins are secreted during the early phase of infection and could potentially be used for vaccine candidates. This study aims to clone and express the CFP-10 and ESAT-6 proteins on the pET SUMO Plasmid. PCR with specific primers was used to amplify the genes encoding CFP-10 and ESAT-6 proteins. The PCR products were cloned into pET SUMO plasmids for transformation into competent cells E.coli BL21(DE3). Recombinant protein expression was induced in LB medium using 1 mM IPTG. The yield of recombinant proteins was visualized by SDS-PAGE and western blotting using an Anti-HisTaq Antibody. PCR results showed the target gene sizes to be 304 bp (CFP-10) and 291 bp (ESAT-6). SDS-PAGE and Western blotting revealed proteins at 22kDa (CFP-10) and 18kDa (ESAT-6). The genes encoding the CFP-10 and ESAT-6 proteins of M. tuberculosis have been successfully cloned into the pET SUMO plasmid and expressed in E. coli BL21(DE3) with molecular weights corresponding to the target genes.
