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.

Tarakan City as an archipelago with high maritime activity has a significant risk of water accidents, yet students' swimming skills are still low. This study aims to: (1) evaluate the context of swimming learning in the PJOK curriculum, (2) assess input readiness (teachers, facilities, costs), (3) analyze the learning implementation process, and (4) measure learning outcomes related to student skills and safety. The research used a descriptive qualitative approach with the Context, Input, Process, Product (CIPP) evaluation model. Data sources include principals (4 people), physical education teachers (4 people), and students (16 people) from four junior high schools in Tarakan City. The research instruments were semi-structured interview guidelines, observation sheets, and curriculum document analysis. Data collection techniques were conducted through participatory observation, in-depth interviews, and documentation studies. The data were analyzed qualitatively using cost and benefit analysis techniques to identify the suitability of the program to the needs. The results show that the context of swimming learning is in accordance with the curriculum, but the swimming pool facilities depend on public facilities with limited access. The learning process is in accordance with the lesson plan, but the practice time (2 times/semester) is not sufficient to master the skills. Product evaluation results indicated a good understanding of water safety theory, but low practical swimming skills. Recommendations: (1) Increased frequency of swimming practice, (2) collaboration with local government for the provision of school swimming pools, and (3) teacher training in adaptive teaching methods for beginner students.

In advertising, females are frequently positioned as the center of attention to establish product image through culturally recognized signs and symbols. Advertisements transcend their promotional function, acting as media that both reflect and influence societal perceptions, including gender roles within daily life. This is exemplified in the Vicks VapoRub advertisement titled "Mother's Amazing Hands," which portrays women as mothers perpetually prepared to care for their families. This study investigates the representation of the mother's role within the aforementioned advertisement using Roland Barthes' semiotic theory. The research aims to twofold: 1) identify the denotative, connotative, and mythical meanings embedded within the Vicks VapoRub "Mother's Amazing Hands" ad; and 2) analyze the portrayal of the mother figure through the lens of Barthes' semiotic framework. The research employed a qualitative descriptive approach, utilizing Barthes' semiotic analysis method alongside concepts of social construction of reality, cinematography techniques, and the societal role of mothers. Through the analysis of verbal, non-verbal, audio, and visual elements within the advertisement, the study revealed the multifaceted representation of the mother's role. This includes functions of caregiving, nurturing, and treatment of family members, ultimately portraying the tangible actions a mother takes in providing for her family.

This study attempts to understand how industrial development strategies are closely related to other economic sectors. Like building a house, industrialization is an important foundation country or region's economy, from relying on agriculture to focusing more on industry. Like an ecosystem, each sector needs and influences each other. Emphasizing the importance of cooperation between sectors, such as farmers who provide raw materials for the food industry, or technology companies that create innovations to increase industrial efficiency. In addition, economic diversification, namely developing various types of industries, is also important so that the economy does not rely too much on one sector. Through comparisons between countries, this study good economic Like an orchestra, each sector must play harmoniously to create a beautiful economic melody.

Hydroxyapatite (HAp) is a biomaterial containing calcium phosphate with the chemical formula which is similar to the structure of human bone, so it is good for the purpose of healing human bones and teeth. HAp synthesis has several methods that can affect the results of HAp synthesis, such as the method of mixing CaO with phosphate, namely mixing with ultrasonic machines and magnetic stirrers. However, the discussion about the difference of HAp results with the mixing method of ultrasonic machine and magnetic stirrer is still rarely done. Therefore, it is important to examine and compare the characteristics of HAp synthesized by ultrasonic and magnetic stirrer mixing. The result of XRD test shows that HA1 has a purity of weight percentage (wt.%) of HAp crystal of 99.8%, while HA2 has a weight percentage (wt.%) of HAp crystal of 97.7%. For the FTIR test results of both specimens detected the presence of phosphate groups, and hydoxide, where both are the basic form of hydroxyapatite. Carbonate groups were also detected in the test, but it cannot be said to be bad because carbonate is a natural substitute for phosphate. 

This study aims to analyze the impact of Green Human Resource Management (GHRM) on Employee Green Behavior (EGB), mediated by Green Work Engagement (GWE) and moderated by Individual Green Values. GHRM plays a crucial role in encouraging employees to engage in environmentally friendly practices, yet its impact on EGB is not always consistent. Using a quantitative-explanatory approach, data were collected through questionnaires with a Likert scale distributed to 66 employees involved in sustainability programs at the resort. The results of this study indicate that GHRM and GWE can influence the EGB, GWE can mediates the relationship between GHRM and EGB, IGV can moderates the relationship between GHRM and EGB. Future studies are encouraged to examine the role of employee ambidexterity as a moderating factor in the relationship between GHRM and GWE on EGB. Moreover, it is recommended that future research adopts a longitudinal design and a mixed-methods approach to provide more in-depth insights into employee environmental behavior.

This study investigates the pyrolysis of Oil Palm Empty Fruit Bunches (OPEFB) using the open-source process simulation software DWSIM to evaluate the impact of temperature on product distribution, particularly bio-oil, biochar, and pyrolysis gas. OPEFB, an abundant lignocellulosic waste from Indonesia’s palm oil industry, holds significant potential as a renewable biomass feedstock. The simulation model was developed based on thermochemical conversion principles and was validated against selected experimental data from the literature. Results show that pyrolysis temperature significantly influences the yield and composition of the products. The gas yield increased with temperature up to 460°C, dominated by CO, CO?, and H? due to the decomposition of volatile organic matter. However, gas yield declined beyond 460°C, likely due to secondary reactions converting gas precursors into liquid products. The optimal temperature was found to be around 510°C, offering a balanced yield of bio-oil and gas with minimal biochar formation. The chemical composition of bio-oil included furfural, phenols, alcohols, and acetic acid—compounds derived from the breakdown of cellulose, hemicellulose, and lignin. Biochar yield decreased with temperature, but its quality improved in terms of carbon content and fixed carbon fraction. This study highlights the utility of DWSIM as an accessible and transparent tool for simulating biomass pyrolysis. Future work should focus on refining the kinetic parameters, experimental validation of simulation results, and integrating downstream processing for fuel and chemical recovery.

The background of this research problem is unmatched between the kinesthetic students characteristic and the reality on the field.
