Ethno-microbiology e-catalog of traditional malay and dayak cuisine in sintang
Full text linkSintang, located in West Kalimantan, is known for its diverse ethnic groups and traditional dishes that are influenced by ethnomicrobiology. This research aims to evaluate the practicality and student reactions to an e-catalog focused on the ethnomicrobiology of Malay and Dayak cuisine from Sintang. The study employs a development approach (R&D) using the 4-D model, which includes four phases: define, design, develop, and disseminate. Data analysis involves assessing the validity and student feedback on the e-catalog. During the define phase, 7 traditional cuisine—pekasam babi, pekasam ikan, rusip, tapai ubi, tempoyak, and tuak ketan—were identified. These dishes were organized into an electronic catalog format in the design phase. The e-catalog was then tested for effectiveness in the development phase, receiving high validity ratings in material (91%), media (96%), and language (89%) aspects. Student responses were very positive, with large-scale test results at 83.80% and small-scale test results at 86.08%. The development of this instructional material was guided by the principles of contextual and culturally responsive education. The findings indicate that the ethnomicrobiology-based e-catalog is a viable and effective learning resource for biotechnology topics. By embedding elements of local wisdom, particularly those relevant to the Sintang region, the e-catalog promotes meaningful learning experiences that are closely aligned with students’ real-life contexts and cultural backgrounds
Undergraduate Students’ Mathematical Problem-Solving Ability in Solving PISA-like Problems
No full textMathematical problem-solving ability was an essential competence, yet many undergraduate students still faced difficulties when confronted with non-routine problems in PISA. This study aimed to describe the mathematical problem-solving abilities of 5th-semester Mathematics Education undergraduates in solving a PISA-like problem with shape content at level 6, which represented the highest level of mathematical proficiency in PISA. Using a qualitative approach, data were collected through a PISA-like problem and interviews, then analysed through data reduction, data display, and conclusion drawing. The results showed that 20% of students had high problem-solving ability, 53.33% medium, and 26.67% low. High-category students met all problem-solving indicators. Medium-category students reached the carrying out the plan indicator but skipped looking back. Low-category students only met the understanding the problem indicator and struggled to identify appropriate strategies and formulas. The study concluded that most students were in the medium category, with limited mastery of higher indicators
Psychological Well-Being of Adolescents Experiencing Bullying: The Role of Family Functioning, Friendship Quality, and Resilience
Full text linkAdolescent victims of bullying often struggle to socialize and often experience some unpleasant feeling such as sense of uselessness, lack of confidence, anxiety, loneliness, sadness, and even suicide attempt. This study sought to investigate how family functioning, friendship quality, and resilience influence the psychological well-being of adolescents who had been bullied. This quantitative study involved 371 junior high school adolescents from Surakarta who had experienced bullying. Data were gathered using a validated family functioning measure, friendship quality scale, resilience scale, and psychological well-being scale. The data were then analyzed using the Structural Equation Model Partial Least Squares (SEM-PLS). The findings suggest that despite their low predictive accuracies, all three variables have great predictive power and may considerably explain the effect of predictor factors on the adolescents’ psychological well-being of who are bullied. Current study's practical implications include that stakeholders, such as parents, teachers, and psychology practitioners, should pay attention to and develop these qualities in order to enhance the psychological well-being of adolescents who are bullied

Implementation of Group Counseling Services Based on Cognitive Behavior Modification with Self-Management Techniques to Reduce Nomophobia among Senior High School Students
Full text linkNomophobia, defined as excessive anxiety due to the absence of access to smartphones, has become a widespread psychological problem that disrupts students' concentration, motivation, and academic achievement. As many as 84.2% of high school students in Indonesia have been reported to experience severe nomophobia symptoms. This quasi-experimental study aims to test the effectiveness of group counseling services based on the Cognitive Behavior Modification (CBM) approach integrated with self-management techniques in reducing nomophobic behavior among high school students. A total of 20 eleventh grade students (aged 16–17 years) at SMA Negeri 17 Padang were divided into two groups: an experimental group (n = 10) that received five sessions of group counseling based on Cognitive Behavior Modification (CBM) with self-management techniques, and a control group (n = 10) that received conventional counseling. Data were collected using an adapted version of the Nomophobia Questionnaire (NMP-Q) (33 items, four dimensions, α = 0.781) and analyzed with nonparametric tests (Wilcoxon Signed-Rank Test and Mann-Whitney U Test) at a significance level of α = 0.05. The research results showed that the experimental group experienced a significant decrease of 41.3% (from M = 121.7, high category, to M = 84.7, low category), compared to the control group which only decreased by 12.9% (from M = 116.4 to M = 105.8). Statistical analysis showed significant differences both within groups (Wilcoxon Z = -2.803, p = 0.005) and between groups (Mann-Whitney U = 11.500, Z = -2.911, p = 0.004). Group counseling based on Cognitive Behavior Modification (CBM) integrated with self-management techniques proved effective in reducing nomophobic behavior through cognitive restructuring and self-regulation, and is therefore recommended as a structured intervention to address technology related anxiety in educational settings
Academic Dishonesty Differences Evaluated by Academic Identity Status in Undergraduate Students
Full text linkAcademic dishonesty has become a pressing concern in higher education, as illustrated by 2024 data from the Indonesian Corruption Eradication Commission (Komisi Pemberantasan Korupsi, KPK) indicating that more than half of respondents admitted to engaging in cheating. Such behavior may be shaped by academic identity status, defined as an individual’s self-perception and commitment within the academic domain. However, empirical evidence on this association remains scarce, particularly among Indonesian undergraduate students. The present study examined differences in academic dishonesty across academic identity statuses in a sample of 216 Indonesian undergraduates aged 18–25 years. Using a quantitative design, participants completed the Academic Dishonesty Scale and the Academic Identity Measure (AIM). A one-way ANOVA revealed significant differences in academic dishonesty scores across identity statuses, F(3, 212) = 5.239, p = .002, η² = .069. Post hoc comparisons indicated that students with a moratorium identity status reported higher levels of academic dishonesty than those with an achievement identity status, whereas no other pairwise differences reached statistical significance. These findings extend the literature on academic dishonesty by integrating identity status theory within the Indonesian higher education context and suggest that academic identity development should be considered when designing targeted preventive and remedial interventions in universities
Cybervictimization, Self-esteem and Perceived Social Support: Resilience Role as the Mediating Variable
Full text linkCyberbullying significantly impacts mental health, contributing to decreased self-esteem, self-harm, and suicide among adolescents. While previous research has established links between self-esteem, social support, and cyberbullying, the underlying mechanisms remain unclear, particularly the potential mediating role of resilience. This study aimed to address this gap by examining whether resilience mediates the relationship between perceived social support, self-esteem, and cyberbullying. A quantitative methodology was adopted, involving a sample of 994 middle-school students aged 12 to 17 years from urban regions in East Java, Jakarta, West Java, and Bali. Structural Equation Modeling (SEM) was employed to perform mediation analyses. Findings indicated that resilience does not mediate the relationships among self-esteem, perceived social support, and cyberbullying. Furthermore, self-esteem and perceived social support emerged as stronger direct predictors of cyberbullying in the absence of resilience as a mediator. Although self-esteem significantly predicts resilience, perceived social support exhibited only a limited predictive ability in relation to resilience. These findings highlight the need for further research to explore alternative pathways through which self-esteem and social support influence cyberbullying, as well as the contextual factors that may affect resilience in adolescent populations
Formulation of a sheet mask essence incorporating Betel leaf (Piper betle L.) ethanol extract and its antibacterial efficacy against Propionibacterium acnes
Full text linkBetel leaf (Piper betle L.) encompasses a multitude of bioactive constituents, including tannins, saponins, flavonoids, alkaloids, and terpenoids, which possess significant antibacterial properties. An ethanol extract derived from betel leaf was meticulously formulated and assessed for its potential as an antibacterial agent specifically targeting Propionibacterium acnes, a bacterium associated with the etiology of acne. This investigation was undertaken with the aim of mitigating the antibiotic resistance commonly observed with traditional acne therapies. The ethanol extract of betel leaf was incorporated into a sheet mask essence, resulting in the development of four distinct formulations (F0, F1, F2, and F3), which were subsequently subjected to comprehensive evaluations of their physical quality and stability. The formulation exhibiting optimal physical characteristics and stability was further scrutinized for its antibacterial efficacy against Propionibacterium acnes. The antibacterial performance of the selected formulation was benchmarked against a positive control comprising a sheet mask infused with clindamycin gel, as well as another containing tea tree oil. Empirical results identified Formula 2, containing 1.5% ethanol extract of betel leaf, as the most efficacious formulation. Formula 2 demonstrated pronounced antibacterial activity against Propionibacterium acnes, with an inhibitory zone measuring 24.67 mm. Although this inhibitory zone was slightly less extensive than that produced by the clindamycin gel sheet mask (32.00 mm), it was comparable to the tea tree oil sheet mask, which exhibited an inhibitory zone of 23.00 mm. In conclusion, the selected sheet mask formulation (Formula 2) exhibits significant antibacterial activity against Propionibacterium acnes, surpassing the efficacy of commercially available tea tree oil sheet masks, thereby presenting a promising alternative for acne management with a diminished risk of promoting antibiotic resistance
Comparative trends and effectiveness of amlodipine and nifedipine as oral antihypertensives in preeclampsia management
Full text linkThe use of amlodipine in preeclampsia remains limited as it is not a treatment option officially. Whereas amlodipine's long half-life allows less frequent dosing in preeclampsia patients, potentially improving preeclampsia treatment more efficiently compared to nifedipine (standard medicine). Ensuring the effectiveness of amlodipine for preeclampsia is essential for optimizing delivery outcomes, in addition to efficiency aspects. However, the effectiveness study of amlodipine in preeclampsia patients is still not definitively known. This study aims to determine the prescription trends and effectiveness of amlodipine as an antihypertensive in preeclampsia. The study used a cross-sectional approach conducted at a one of the secondary healthcare facilities in Tasikmalaya, utilizing medical records from January 2019 to December 2023. The data were analyzed using Chi-Square test to determine the trends using and effectiveness of amlodipine compared to nifedipine in controlling blood pressure in preeclampsia. The study shows that the trends using of amlodipine in preeclampsia is decreasing over the past 5 years (2019 to 2023). This phenomenon may be influenced by limited evidence, established clinical practice guidelines, and priority of drug use. There was no significant difference in effectiveness of amlodipine compared to nifedipine in single therapy (p= 0.698) or dual therapy (p=0.1). Furthermore, the study found that amlodipine and nifedipine exhibited comparable effectiveness in controlling blood pressure in preeclampsia. Therefore, amlodipine may be considered as an alternative antihypertensive option for controlling blood pressure in preeclampsia
