Abstract

The eye area is the part of the face that most quickly shows signs of fatigue which is influenced by various factors. Green Tea Leaves (Camellia sinensis L.) are known as one of the plants that have high antioxidant content. The antioxidant content in green tea leaves can protect the skin from free radicals that can accelerate the appearance of signs of fatigue, including in the eye area. This study aims to develop an innovative cosmetic preparation in the form of an eye stick and determine the formula with variations in the concentration of Green Tea (Camellia sinensis L.) leaf extract that has the best antioxidant activity and good stability of the preparation. This study is an experimental study with two variations of extract concentration, namely 1% and 6%, which are obtained through an extraction process using 96% ethanol. The eye stick preparation was evaluated through organoleptic tests, pH, homogeneity, adhesion, melting point, and stability. Antioxidant activity was tested using the DPPH method with absorbance measurements using a UV-Vis spectrophotometer. The results showed that the green tea leaf eye stick preparation had good stability and antioxidant activity in F2 with an extract concentration of 6%, with an IC50 value of 57.2222 ppm, which is categorized as a strong antioxidant.

Abstract

Sumatra Island has complex geological conditions as it is located in a collision zone between the northward-moving Indo-Australian Plate and the relatively stable Eurasian Plate. The interaction of these two plates forms two main tectonic structures: the subduction zone off the western coast of Sumatra and the Sumatra Fault Zone (SFZ). The latter exhibits varying seismic activity that has not yet been clearly mapped. This study aims to assess the level of seismic vulnerability across Sumatra Island by dividing the region into nine zones using the a-value and b-value parameters based on the Gutenberg-Richter relationship. Earthquake data from the USGS and IRIS catalogs for the period 1924-2024 were processed through a declustering procedure and subsequently analyzed using the Maximum Likelihood method with the assistance of ZMAP v6 software. The results show that the a-value across Sumatra ranges from 2.1 to 5.1, while the b-value ranges from 0.545 to 0.868. North Sumatra records the highest a- and b-values, at 3.82 and 0.786, respectively. In contrast, West Sumatra shows the lowest values, with an a-value of 2.9 and a b-value of 0.623. These findings not only reveal variations in seismic activity across Sumatra Island, but also provide a more detailed zonation of seismic hazard based on the Gutenberg-Richter parameters, which can serve as a basis for disaster mitigation planning and the development of earthquake-resistant infrastructure.

Abstract

This research is motivated by students' low self-confidence, demonstrated by a lack of courage to express opinions, participation in learning, and social interaction in the classroom. Self-confidence is an important aspect of students' personal development, influencing their learning success and adjustment. This study aims to determine the difference in students' self-confidence levels before and after being given group guidance services using expressive writing techniques. This research used an experimental research design with a one-group pretest-posttest design. The sample consisted of 8 students selected using a purposive sampling technique. Based on the pretest and posttest data, the mean score before treatment was 74, which is considered low, and after treatment, it showed an increase with a mean score of 84. The paired t-test analysis obtained a significance value of 0.001 <0.05, indicating a significant difference in students' self-confidence levels before and after being given group guidance services using expressive writing techniques for 7 meetings. Thus, group guidance services using expressive writing techniques have proven effective in increasing the self-confidence of 10th-grade students at SMA Negeri 2 Samarinda.

Abstract

This study aims to determine whether student learning outcomes taught using the Chemsketch-assisted problem-based learning model are higher than those taught using conventional learning, and to determine student responses to the model and media applied. This study used a quasi-experimental design with a pretest-posttest control group design. Two classes were selected using purposive sampling: an experimental class using Chemsketch-assisted problem-based learning, and a control class using conventional learning. The results showed an average learning outcome of 86.80 for the experimental class and 68.05 for the control class. The analysis showed that the data were normally distributed and homogeneous. Hypothesis testing revealed a significant difference between the learning outcomes of the two classes, with the class using Chemsketch-assisted problem-based learning achieving higher learning outcomes than the conventional class. Student responses to the model and media application were in the very good category, with a percentage of 82.73%. These findings indicate that Chemsketch-assisted problem-based learning is effective in improving student learning outcomes in hydrocarbon compounds.

Abstract

Physical condition is a key factor determining futsal players' performance, as matches are played at high intensity and demand optimal aerobic and anaerobic capabilities. However, the physical condition profiles of school-level futsal athletes are rarely comprehensively evaluated to serve as a basis for training program design. This study aims to describe the physical condition levels of male futsal players at MAN 1 Mataram. A quantitative approach with a descriptive design was employed. The sample consisted of 16 players selected using total sampling. Data collection involved the Multistage Fitness Test (MFT) to measure VO₂Max, a 30-meter sprint test, the Illinois agility test, a 60-second push-up test, and a vertical jump test. Data were analyzed using descriptive statistics specifically mean values ​​and percentages based on the norms for each test instrument. The results showed that leg muscle explosive power averaged 51.56 cm (predominantly "good" category), sprint speed averaged 4.15 seconds ("good" category), agility averaged 17.14 seconds ("fair" category), and upper-body muscle strength averaged 31.56 repetitions. Meanwhile, the mean VO₂Max was 40.87 ± 3.37 ml/kg/min, with the majority of players (68.8%) falling into the "poor" category. These findings indicate that while the players possess adequate anaerobic performance capabilities to support explosive actions, they lack the aerobic capacity necessary to sustain match intensity throughout the game. Consequently, these results can serve as a foundation for developing a more targeted physical training program that emphasizes improving aerobic endurance through structured training, without neglecting the development of other physical fitness components.

Abstract

This pre-experimental study, utilizing a one-group pretest-posttest design, aimed to examine the validity and effectiveness of a Project-Based Learning (PjBL)-based Student Worksheet on the topic of environmental pollution regarding students' critical thinking skills and cognitive learning outcomes. The study population comprised all students at SMAN 8 Mataram, with class X MIPA 1 selected as the sample using a non-random sampling technique. Data were collected using instruments consisting of a critical thinking essay test (6 items), a cognitive multiple-choice test (12 items), and expert validation sheets. Data analysis employed Aiken’s V index for validity and the N-Gain formula to measure competency improvement. The results indicated that all materials fell into the "highly valid" category, with average Aiken's V indices of 0.89 (teaching module), 0.76 (LKPD), 0.87 (critical thinking test), and 0.89 (cognitive test). The implementation of the PjBL-based LKPD proved sufficiently effective in enhancing student abilities, as evidenced by N-Gain scores of 0.57 for critical thinking skills (57.55% effectiveness) and 0.56 for cognitive learning outcomes (56.20% effectiveness). Integrating PjBL syntax into this LKPD effectively facilitated independent thinking and students' mastery of essential concepts.
