Based on Law No. 11 of 2006 and Qanun Aceh No. 4 of 2010, the Government of Aceh has special authority in implementing prioritized health services for poor communities as part of its special autonomy. In practice, the Aceh Health Insurance (JKA) program provides health coverage for all Acehnese residents, including underprivileged groups, by covering insurance contributions and several referral and companion costs not fully guaranteed by the national health insurance system. This study aims to analyze the implementation system of JKA, examine the responsibility of the Aceh Government in providing health insurance for its citizens, and evaluate the government’s obligation to pay contributions for poor participants. This research uses an empirical juridical method with a sociological approach and utilizes both primary and secondary data. The results show that several provisions in the Qanun as the legal basis for JKA implementation are not fully aligned with field conditions and the Social Security Administrator Law. In practice, the Aceh Government bears insurance contributions and various referral costs for residents, including poor communities. Although the obligation to pay contributions for the poor has been implemented, funding for referral transportation, companions, and their consumption has not been fully covered, especially for inter-regional advanced healthcare services. Therefore, the Aceh Government needs to revise Article 43 of Qanun Aceh No. 4 of 2010 and evaluate the JKA program to ensure more targeted healthcare financing.

Environmental pollution and degradation remain serious issues in Indonesia, causing significant impacts on ecosystems and the social life of communities. One of the fundamental principles in environmental law aimed at ensuring ecological restoration is the Polluter Pays Principle (PPP), which obliges polluters to bear all costs arising from environmental pollution or damage caused by their activities. This study aims to analyze the effectiveness of enforcing the Polluter Pays Principle as a mechanism for ecological restoration in resolving environmental disputes in Indonesia. The research employs a normative legal research method using statutory and conceptual approaches. The findings indicate that although the Polluter Pays Principle has been normatively adopted in Law Number 32 of 2009 on Environmental Protection and Management, its implementation in practice remains suboptimal. Major obstacles include weak law enforcement, power imbalances between business actors and affected communities, lack of transparency in the use of compensation funds, and limited public participation in environmental restoration processes. Therefore, strengthening regulatory frameworks, enhancing the capacity of law enforcement institutions, and adopting a restorative justice approach are necessary to ensure that the Polluter Pays Principle functions effectively in achieving ecological restoration and environmental justice in Indonesia.

Air pollution constitutes a significant environmental problem with far-reaching impacts on public health, quality of life, and ecosystem sustainability, particularly in urban areas and industrial zones in Indonesia. Although the national environmental legal framework has adopted the principle of strict liability through Law Number 32 of 2009 on Environmental Protection and Management, its implementation in air pollution cases continues to face substantial challenges, especially with regard to the proof and assessment of non-material damages. Non-material damages such as disturbances to living comfort, deterioration of environmental quality, psychological stress, and health-related anxiety are intangible in nature and lack clear measurement standards, resulting in their frequent exclusion or inadequate consideration in environmental civil litigation. This study aims to analyze the legal basis for the application of the strict liability principle to air pollution cases in Indonesia, identify relevant forms of non-material damage, and examine the implications of the absence of standardized methods for assessing such damages on legal certainty and the effectiveness of corporate liability enforcement. The research employs a normative legal research method with a library-based approach, incorporating statutory, conceptual, and case approaches. Legal materials are analyzed qualitatively using a descriptive-analytical method, drawing upon legislation, court decisions, and scholarly literature on environmental law and environmental damage valuation. The findings indicate that the absence of standardized criteria for assessing non-material damages leads to evidentiary difficulties, inconsistent court decisions, and a weakened deterrent effect on polluting corporations, thereby preventing the full realization of victims’ rights to effective remedies. This study underscores the urgency of developing an integrated national technical guideline for the assessment of non-material environmental damages based on scientifically grounded valuation methods, as well as the need for cross-institutional policy harmonization to strengthen legal certainty, access to justice for affected communities, and corporate accountability in controlling air pollution.

Combined spinal epidural (CSE) is a regional anesthesia technique that combines the rapid onset of spinal anesthesia with the flexibility and prolonged analgesia of epidural anesthesia, making it a valuable option for major surgery in elderly patients with comorbidities. We report a case of a 76-year-old man with ASA physical status III diagnosed with multiple nephrolithiasis accompanied by bilateral hydronephrosis, who underwent open right nephrolithotomy under CSE anesthesia. The patient had a history of hypertension and mild renal function impairment, placing him at increased perioperative risk. Intraoperatively, hemodynamic parameters remained stable without significant hypotension, vasopressor requirement, or conversion to general anesthesia. Estimated blood loss was approximately 500 mL and was managed with crystalloid replacement without transfusion. Prophylactic antibiotic and adjuvant medications were administered according to surgical standards. Postoperatively, the patient was monitored in the ICU with stable vital signs and adequate pain control achieved through continuous epidural analgesia. This case highlights that CSE can be a safe and effective anesthetic approach for open nephrolithotomy in selected high-risk geriatric patients, providing satisfactory hemodynamic stability and postoperative recovery.

Background: Recurrent Aphthous Stomatitis (RAS) is one of the most frequently encountered oral mucosal conditions. Although RAS has been extensively considered clinically and through research, ulcer occurrence remains unavoidable, and most treatment approaches are primarily symptomatic. Objective: To identify anxiety as a predisposing factor in patients with minor RAS. Case Report: A 24-year-old female patient presented to Soelastri Dental and Oral Hospital with a complaint of an ulcer on the right upper lip. The patient reported pain and a burning sensation for the past four days. The pain worsened when consuming hot food or beverages. The patient had experienced similar episodes previously but had never sought treatment for this condition. Intraoral examination revealed a single shallow ulcer with an oval shape, regular margins, a yellowish-white base surrounded by an erythematous halo, measuring 3 × 2 mm on the right upper lip, and was symptomatic. Case Management: The treatment provided focused primarily on Communication, Information, and Education (CIE). The patient was informed about the predisposing factor experienced, which may contribute to the occurrence of RAS, namely anxiety. The patient also received education regarding maintaining oral hygiene, consuming fruits and vegetables, increasing water intake, eating more regularly, attending a follow-up visit seven days after treatment, and managing anxiety. Conclusion: In this case, RAS management was focused on eliminating predisposing factors, particularly anxiety, which was strongly suspected to be the triggering factor for minor RAS in this patient.

Anemia in toddlers is a serious nutritional problem that impacts physical growth, cognitive development, and the child's immune system. This study aims to provide an overview of the level of knowledge, attitudes, and practices of parents in preventing anemia in toddlers. This quantitative study involved 50 respondents using a structured questionnaire instrument covering the domains of knowledge, attitudes, practices, and sources of health information. The results showed that respondents' knowledge was in the adequate category; although all respondents (100%) understood the negative impact of anemia on growth and intelligence, only 80% understood the technical definition and clinical symptoms accurately. In the attitude domain, respondents showed a very positive response (100%) to the importance of balanced nutrition and early prevention. Regarding the practical aspect, although regular visits to integrated health posts (Posyandu) reached 100%, the consistency of daily animal side dish intake remained at 80%. An interesting finding showed a shift in information sources, with social media (80%) dominating over direct exposure to information from health workers (40%). This study concluded that there is a gap between positive attitudes and consistent daily practices, and the need to optimize health education through digital media by medical personnel to reduce the incidence of anemia in toddlers.

Nutritional status plays an important role in shaping body image among adolescents, particularly female adolescents who experience rapid physical and psychosocial changes. Adolescents with nutritional problems are more likely to feel dissatisfied withitheiribody shape, whichimay lead to unhealthy behaviors such as strict dieting or excessive eating to gain weight. Thisistudy aimed toianalyze theirelationship betweeninutritional statusiand bodyiimage amongifemale adolescentsiat SMK Negeri 1 Palu. This research employedia quantitativeiapproachiwith aicross-sectionalidesign. Aitotal ofi169 femaleistudentsiwere selected using stratified random sampling. Body image data were collected using the Body Self Relation Questionnaire–Appearance Scale, while nutritional status was assessed using Body Mass Index for Age (BMI-for-Age) and Height for Age (HFA). Data were analyzed using the Spearman Rank correlation test. The results indicated that there was no significant relationship between nutritional status based on BMI-for-Age and body image, with a p-value of 0.329. Similarly, no significant relationship was found between Height-for-Age and body image among female adolescents, with a p-value of 0.892. Most respondents were aged 16–17 years, had a negative body image perception, normal BMI-for-Age nutritional status, and normal Height-for-Age category. These findings suggest that body image among female adolescents is not solely influenced by nutritional status but may also be affected by other psychosocial and environmental factors. Therefore, future research is recommended to apply a cohort study design and explore other determinants of body image, such as social media exposure, peer influence, and infectious diseases, to provide a more comprehensive understanding of factors affecting adolescent body image.

Oral candidiasis pseudomembranous is an infection of the oral cavity caused by microorganisms such as fungi, specifically due to the overgrowth of Candida albicans. It frequently manifests in individuals with impaired local or systemic immunity, or those with specific behavioral risk factors. Predisposing factors, such as habitual alcohol consumption and smoking, play a significant role in reducing the resilience of the oral mucosa and altering the balance of the normal oral flora. This case report aims to examine the correlation between behavioral risk factors and the development of pseudomembranous oral candidiasis. A 22-year-old male was reported to have a lesion consisting of thick, raised, whitish plaques that were non-scrapable and asymptomatic. The patient had an unhealthy lifestyle, including alcohol consumption and smoking two packs per day, along with poor oral hygiene. To confirm the suspicion of oral thrush, a potassium hydroxide (KOH) examination was performed, which revealed the presence of Candida albicans. This led to therapeutic management using Nystatin (Candistatin) and Chlorhexidine, complemented by mechanical treatment with a tongue scraper. Pseudomembranous oral candidiasis in this 22-year-old male patient is a classic example in which local behavioral risk factors and lifestyle act as the main triggers of infection.

Hypertension is a significant global health problem, especially in specific groups such as pregnant women. The high incidence and potential for serious complications demand non pharmacological management efforts and innovative use of local foods. This study examines the potential of local functional foods such as Ambon bananas, banana blossoms, and bamboo shoots as alternatives for health management and product development, particularly those related to hypertension in pregnant women. The method used was a systematic literature review using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach, which encompasses four main stages: identification, screening, feasibility assessment, and analysis of results.The study results showed that the Ambon banana diet significantly reduced systolic and diastolic blood pressure. Factors such as age, family support, stress levels, and fast food consumption were shown to be significantly associated with the incidence of hypertension in pregnant women. Furthermore, bamboo shoot consumption significantly reduced blood cholesterol levels and blood pressure. In terms of product innovation, the fish floss formulation combined with banana blossoms or bamboo shoots received positive feedback from the panelists. The fermentation process of bamboo shoots is known to produce flour with a very high crude fiber content. Therefore, this local food has significant potential as a source of additional fiber and a raw material for value-added processed products to support food security and improve public health.

Crackers are snacks that are popular with various age groups, but generally have a relatively low calcium content so they do not contribute to meeting daily mineral needs. Therefore, food product innovations are needed to increase their nutritional value, one of which is by utilizing purebred chicken egg shells as a natural source of calcium. This study aims to analyze the effect of purebred chicken eggshell flour substitution on the acceptability of crackers and determine the best formulation as a high-calcium snack. The research method used an experimental design with a Complete Random Design (RAL) consisting of four treatments, namely P0 (100:0), P1 (90:10), P2 (85:15), and P3 (80:20). The testing is carried out qualitatively through organoleptic tests which include color, aroma, taste, and texture. The data was analyzed using the one-way ANOVA test and followed by the Post Hoc Kruskal-Wallis test if there were significant differences. The results showed that the best formulation was found in the P1 treatment with a 10% substitution of eggshell flour. Overall, the substitution of purebred chicken eggshell flour had no significant effect on the acceptability of crackers.

Land conflict between the Sihaporas indigenous community and PT Toba Pulp Lestari (TPL) remains an ongoing agrarian issue that directly affects the community’s livelihoods. The inclusion of the company’s concession within the customary territory has changed patterns of land control and use that were previously managed collectively across generations. This situation restricts access to agricultural land and forests, reduces sources of income, and creates social tensions and confrontations. This study aims to analyze the impacts of land conflict on the Sihaporas indigenous community and to examine the conflict through a political ecology perspective with a focus on power relations among actors. Using a qualitative case study approach, data were collected through interviews, observations, and document analysis. The findings show that the conflict affects economic, social, and cultural aspects of the community and reflects unequal power relations between indigenous peoples, corporations, and the state in controlling agrarian resources.

Background: Hand grip strength is an essential indicator of physical capacity and nutritional status that can identify obesity risk. Adipose tissue accumulation in central obesity contributes to decreased hand grip strength quality through impaired muscle force transmission. Previous studies showed inconsistent results regarding the relationship between waist circumference and hand grip strength, especially in populations with high physical activity. Objective: To analyze the relationship between waist circumference and hand grip strength in male construction workers with high physical activity in Medan City. Methods: This descriptive-analytic study with cross-sectional design involved 100 male construction workers aged 30-39 years selected using purposive sampling technique. Waist circumference was measured using measuring tape, while hand grip strength was measured using handgrip dynamometer. Data analysis used Chi-Square test with significance level α=0.05. Results: The majority of respondents had normal waist circumference (64%) with mode 70 cm and normal grip strength category (53%) with mode 41.7 kg. Chi-Square test showed significant relationship between waist circumference and hand grip strength (p=0.039). Conclusion: There is a significant relationship between waist circumference and hand grip strength in construction workers. High physical activity does not completely prevent central obesity, therefore nutritional management and health education programs are needed for optimization of body composition and muscle functional capacity.

Introduction: Maximal oxygen volume (VO2max) is the capability of the cardiorespiratory system to deliver oxygen to muscle mitochondria, which is directly proportional to the level of stamina and is obtained from physical activity. Central obesity, which is characterized by excessive accumulation of visceral fat, can cause decreased stamina, so individuals with central obesity tend to have lower VO2max values. VO2max values can be determined by body composition, such as waist circumference, which is an indicator of central obesity. Methods: This study used an observational analytical design with a cross-sectional approach and involved 54 male respondents with high physical activity jobs who worked as building construction workers in Medan City, North Sumatra Province. Waist circumference measurements were carried out using a measuring tape, while VO2max was assessed using a 6-minute walk test. Statistical analysis was performed using the Spearman correlation test with a significance level of 0.05. Results: A total of 47 respondents (87%) had a normal waist circumference, 31 respondents (57.4%) had a fair VO2max, and 16 respondents (29.6%) had an average VO2max. The analysis showed a significant relationship between waist circumference and VO2max, with a P value of 0.000 (P<0.05) and R = -0.658. Conclusion: There is a strong and significant negative correlation between waist circumference and VO2max. This indicates that a larger waist circumference results in a lower VO2max, and a smaller waist circumference results in a higher VO2max.
