Postherpetic neuralgia (PHN) is a chronic neuropathic pain complication following herpes zoster infection. PHN often leads to persistent pain and facial muscle dysfunction, affecting patients' quality of life. This study aimed to evaluate the physiotherapy management using electrical stimulation and facial exercises in a case of facial PHN. A case report design was used to observe a 36-year-old male patient presenting with facial pain and muscle weakness after herpes zoster infection. The physiotherapy intervention, consisting of electrical stimulation and facial exercises, was conducted over three sessions within two weeks. Assessment tools included NPRS, MMT, and Ugo Fisch Scale. There was a significant reduction in pain from NPRS 5/10 to 0, and improvement in frontal muscle strength from MMT 0 to 3. The Ugo Fisch score increased from 62 to 66, indicating functional improvement of facial muscles, though not yet optimal. Electrical stimulation and facial exercises were effective in reducing pain and improving facial muscle function in a PHN patient. Further research with larger samples is needed to validate these findings.

The increasing demand for Computational Thinking (CT) and Environmental Awareness (EA) in elementary science education highlights the need for innovative and culturally relevant learning approaches. However, traditional science teaching methods often emphasize rote memorization rather than problem-solving and ecological responsibility, leading to a lack of deeper conceptual understanding among students. This study investigates the influence of Unplugged Coding Learning integrated with Tri Hita Karana (THK) spiritual values on the development of CT and EA in elementary school students. This research employs a quasi-experimental design with a pretest-posttest control group approach. Data were collected using multiple-choice assessments for CT and EA and were analyzed using Multivariate Analysis of Variance (MANOVA) to determine the effectiveness of the intervention. The results indicate that students who participated in Unplugged Coding Learning with THK values demonstrated significantly higher gains in CT skills (logical reasoning, problem-solving, and pattern recognition) and EA (understanding sustainability and conservation principles) compared to the control group. The Palemahan aspect of THK, which emphasizes harmony with nature, contributed to students’ increased awareness of environmental issues. These findings suggest that integrating local wisdom into STEM education enhances both cognitive and ethical development. The study implies that culturally embedded educational approaches can bridge computational problem-solving skills with environmental consciousness, fostering a more holistic learning experience. Future research should explore long-term impacts and adaptability of this model across different educational settings.

Disaster-prone regions require an education system that equips students with both scientific understanding and disaster preparedness. However, integration of disaster mitigation content into subject-specific learning, particularly physics, remains limited. This study aims to develop and evaluate the effectiveness of physics teaching materials integrated with disaster mitigation education to enhance students’ disaster literacy skills. A mixed-method approach with an exploratory sequential design was employed. The development process followed the 4D model (Define, Design, Develop, and Disseminate) to systematically design and implement teaching materials. The study was conducted in two high schools in South Lampung Regency, Lampung, Indonesia involving four classes (two experimental and two control groups) with a total of 128 students, consisting of 63 students in the experimental groups and 65 in the control groups. The T-test results show that the use of disaster mitigation-based teaching materials had a statistically significant effect on students' disaster literacy abilities, with a significance value of 0.000 (p < 0.05).  Furthermore, the results of the effect size analysis (Cohen’s d = 0.62 and 0.66) fall within the moderate category, confirming that this intervention had a significant impact on enhancing students’ disaster literacy skills related to disaster mitigation. The implementation of this teaching material not only enhances students’ understanding of physics concepts but also increases their awareness and preparedness for disasters, particularly around disaster literacy, making it a strategic innovation in disaster education. This research contributes significantly to the development of disaster education curricula in Indonesia, particularly within the context of physics education.

Posbindu Dahlia Indah located in Petukangan Selatan Village has developed into a center for community empowerment activities based on local potential, especially in the production of tea bags from butterfly pea flowers (Clitoria ternatea). This product has added value both in terms of economy and health benefits, thus promising broad market opportunities. However, limitations in human resource (HR) management, such as lack of technical skills, suboptimal division of tasks, and minimal knowledge about packaging and marketing, are the main obstacles in increasing production and distribution capacity. This study aims to identify the main challenges in the production process and formulate empowerment strategies through HR training and optimization. The methods used include direct observation of production activities, focus group discussions (FGD) to explore problems and solutions from the perspective of group members, and skills training tailored to local needs. The training covers technical aspects of production, sanitation, packaging, and the basics of community marketing. The results of the study showed that training designed in a participatory manner was able to improve technical skills and self-confidence of group members. A more structured division of tasks also increased the efficiency of the production process. In addition, there is an increase in collective awareness of the importance of building local brands and utilizing social media as a means of promotion. This program not only has an impact on increasing production capacity, but also strengthens social ties between members and creates a spirit of community-based economic independence. This study recommends strengthening ongoing mentoring and expanding marketing networks as strategic steps to support the sustainability of the butterfly pea flower tea bag production business at Posbindu Dahlia Indah. The results of this study are expected to be a model for local economic empowerment that can be replicated in other communities with similar potential.
