Tuberculosis (TB) remains a major global public health problem and is one of the leading causes of death after HIV/AIDS. This disease has a high transmission rate, especially among children. This study aims to identify and analyze the determinants contributing to the incidence of tuberculosis in children based on previous studies. The method used was a literature review, which analyzed scientific articles related to the determinants of TB in children. Articles were searched through databases such as Google Scholar, Crossref, and Sinta using related keywords. Of the five articles that met the inclusion criteria, it was found that a history of contact with an adult TB patient was the main factor in transmission in children. Children are highly susceptible to contracting TB germs transmitted through droplets from coughing or talking. In addition, BCG immunization can provide protection against TB infection in children by developing antibodies. A scoring system was used to examine the history of contact in children at risk. In conclusion, there is a significant relationship between history of contact and the incidence of TB in children. Therefore, it is important for adult TB sufferers who live with children to practice preventive behaviors, such as cough etiquette, wearing masks, and proper phlegm disposal.

The results of the study indicate that the interactive flipbook media inspired by the local wisdom of North Sulawesi was considered very valid by experts. Furthermore, practicality testing demonstrated that teachers and students responded in the "very practical" category, indicating that the media was easy to use and well-received in learning. The application of local cultural elements has been shown to help students understand figurative language concepts more clearly and meaningfully. Therefore, the developed flipbook can be used as an alternative Indonesian language learning medium to improve students' semantic understanding and cultural knowledge in elementary schools.

Forestry crimes remain a serious and recurring problem that threatens forest sustainability in Lampung Province and causes long-term environmental damage. The use of repressive penal approaches alone has been considered ineffective, as such measures tend to focus on punishment after violations occur rather than preventing crimes in advance. Therefore, this study aims to analyze non-penal efforts in preventing forestry crimes and to identify factors that hinder their effective implementation. The research used a normative juridical approach supported by an empirical approach through literature studies and interviews. The results show that non-penal strategies, including guidance, counseling, community empowerment, and conservation partnership programs implemented by the Tahura Wan Abdul Rachman KPHK UPTD, have contributed to reducing forestry crimes. Nevertheless, several obstacles continue to limit their effectiveness, such as overlapping regulations, limited numbers of law enforcement officers and supporting infrastructure, challenging socio-economic conditions of communities living around forest areas, and low levels of legal awareness and legal culture among local populations.

Continuous chemical control of rat pests (Rattus spp.) can sometimes lead to resistance and resurgence problems, and even some cases of inaccurate targeting ultimately killing livestock. The idea of ​​​​repelling rats in rice fields using vibrations of crickets and other natural animals transmitted via radio has been done and the results are quite optimal for rat control, but it has not been done in corn cultivation. The purpose of this study was to determine the effect of cat sound audio on the intensity of rat pest attacks (Rattus spp.) in corn (Zea mays L.) plantations. The research location was in a farmer's land owned by a farmer in Dagan Village, Solokuro District, Lamongan Regency. Determination of sampling points using the diagonal method, each into 5 sub-observation plots. In each sub-plot, markers were placed as sampling points. Audio with cat and bird sounds was played continuously from 05.00 pm - 07.00 am. Observations were conducted at 7:00 a.m. at all sampling points at 30 and 60 days after planting. Observations were conducted for three days using audio and three days without audio. Damage symptoms were observed directly at each sampling point. Corn plants showing symptoms were then recorded and analyzed using the Damage Intensity formula. Observations showed that the use of cat sound audio was able to reduce the level of rat infestation. At 30 days after planting, the damage percentage was reduced by 8.33%. Meanwhile, at 60 days after planting, the damage percentage was reduced by 18.33%.

Autonomous decision-making systems increasingly rely on complex artificial intelligence models to operate in dynamic and safety-critical environments. While these models provide strong predictive capabilities, their black-box nature limits transparency, trust, and accountability. This study proposes a structured research methodology for integrating Explainable Artificial Intelligence (XAI) into autonomous decision-making systems. The research adopts a conceptual–analytical approach to develop an explainability-oriented framework that embeds transparency across perception, decision-making, and action execution stages. The methodology includes literature-driven problem identification, conceptual framework construction, classification and mapping of XAI methods, and formulation of explainability evaluation criteria. The results demonstrate that effective explainability in autonomous systems requires a hybrid integration strategy, combining in-model transparency with post-hoc explanation mechanisms. A structured mapping of XAI techniques to autonomous system components and a conceptual decision-flow diagram are presented to illustrate explainability integration. The findings highlight that layered and context-aware explainability enhances system interpretability, supports human oversight, and improves safety relevance without compromising autonomous operation. This study contributes a reusable methodological foundation for the design and evaluation of explainable autonomous systems, offering practical guidance for future empirical validation and real-world deployment in safety-critical applications.

Malnutrition in children remains a serious public health challenge in Indonesia because it directly impacts growth, cognitive development, and the child's future quality of life. Parents play a crucial role in maintaining children's health, particularly in providing balanced nutrition and preventing nutritional problems such as stunting and malnutrition. This study aims to analyze the role of parents in maintaining children's health due to malnutrition based on a literature review. The method used is a qualitative literature study, through a search of various written sources in the form of scientific journals, articles, and relevant books obtained from Google Scholar. The results of the study indicate that the level of knowledge, education, parenting patterns, socioeconomic conditions, and active involvement of parents in monitoring children's growth significantly influence children's nutritional status and health. Parents play a role as providers of nutritious food, nutrition educators, role models of healthy lifestyles, and regular monitors of children's growth and development. Parents' lack of understanding of balanced nutrition, the habit of consuming instant foods, and minimal participation in health programs are risk factors for malnutrition in children. Therefore, increasing parental education and involvement through a family-based approach is an important strategy in efforts to prevent and address child nutrition problems sustainably.

Diabetes mellitus (DM) is a global health problem characterized by increased blood glucose levels. Type 2 diabetes mellitus (T2DM) accounts for 90-95% of all diabetes cases and is characterized by insulin resistance. Persistent hyperglycemia in patients with T2DM increases the risk of various complications, including renal dysfunction. Therefore, monitoring HbA1c levels is important for assessing long-term glycemic control and preventing complications, one of which is impaired kidney function that can be detected through increased blood creatinine levels. To analyze the relationship between HbA1c levels and blood creatinine levels in type 2 diabetes mellitus patients at RSUD ODSK North Sulawesi Province. This study used an observational analytic design with a cross-sectional approach. This study was retrospective using secondary data in the form of medical record data for the period February 2024-August 2025. This study used a total sampling method with 71 patients who met the inclusion criteria. The findings showed that the majority of patients had HbA1c levels >6,5%, while most blood creatinine levels were within the normal range. Based on the results of the Spearman-Rank correlation test, a significance value of 0.040 (p-value <0.05) was obtained. There is a significant relationship between HbA1c levels and blood creatinine levels, with a negative correlation strength in patients with type 2 diabetes mellitus at RSUD ODSK North Sulawesi Province.

This research focuses on the design and evaluation of a novel parallel graph optimization algorithm incorporating dynamic load balancing (DLB) to address inefficiencies in heterogeneous computing environments. Large-scale graph optimization problems, such as those in social networks, bioinformatics, and transportation systems, often suffer from computational imbalances when using traditional static load balancing approaches, leading to underutilized resources and prolonged execution times. The primary objective of this research is to develop an algorithm that can dynamically adjust workload distribution across processors, enhancing computational efficiency and scalability. The proposed method combines heuristic techniques, including region expansion and multilevel partitioning, with diffusive load balancing strategies to minimize inter-processor communication overhead. Experimental results demonstrate that the proposed algorithm reduces execution time by up to 40% compared to static methods, with optimized resource utilization and more balanced workload distribution. The scalability of the algorithm is also evident, as it adapts effectively to increasing problem sizes and processor counts. These findings suggest that dynamic load balancing is crucial for improving parallel graph optimization in real-world applications. Future work will focus on further enhancing the algorithm’s responsiveness to rapidly changing workloads and expanding its applicability to additional domains.

Acne (Acne vulgaris) is one of the most common skin problems, affecting 80–85% of adolescents aged 15–18 years, with some cases persisting into adulthood. One of the associated bacteria is Staphylococcus epidermidis, a normal skin flora that can become an opportunistic pathogen. Bay leaves (Syzygium polyanthum) are known to contain secondary metabolites such as alkaloids, flavonoids, tannins, saponins, and essential oils with antibacterial activity. This study aimed to formulate ethanol extract of bay leaves into ointments with concentrations of 10%, 20%, and 30%, test their antibacterial activity against Staphylococcus epidermidis using the disc diffusion method, and evaluate their physical quality (organoleptic properties, homogeneity, pH, adhesion, and spreadability). Results showed that the ethanol extract of bay leaves contained alkaloids, flavonoids, saponins, and tannins. The ointments met topical quality standards with pH 5.8–6.9, adhesion time 36–41 seconds, and spreadability 6.9–8.1 cm. Antibacterial activity increased with higher concentrations: 7.8 mm (10%), 12 mm (20%), and 15 mm (30%), although still lower than the positive control (clindamycin, 34 mm). In conclusion, ethanol extract of bay leaves has potential as an active ingredient in topical anti-acne ointments, but further studies with higher concentrations, in vivo testing, and optimized formulations are needed to achieve efficacy comparable to synthetic antibiotics.  

Soil-transmitted helminth (STH) infections remain a public health problem among children in tropical regions with high environmental exposure. One potential but underexplored transmission route is toenails, which may serve as a mechanical medium for helminth egg contamination. This study aimed to analyze the association between personal hygiene and STH contamination on children’s toenails in Polimak 1, Jayapura City. An observational analytic study with a cross-sectional design was conducted among school-aged children selected based on inclusion criteria. Personal hygiene data were collected using a structured questionnaire, including handwashing practices, footwear use, and nail care habits. STH contamination on toenails was examined microscopically, and statistical tests were applied to assess associations. The results showed that STH contamination on toenails was still present in a considerable proportion of children, with Ascaris lumbricoides eggs being the most frequently detected. Statistical analysis revealed a significant association between personal hygiene and STH contamination on toenails (p < 0.05), including handwashing habits, footwear use, and nail care practices. This study concludes that personal hygiene plays a crucial role in STH contamination on children’s toenails, and toenails can be used as an indicator of environmental exposure. These findings highlight the importance of consistent personal hygiene practices in preventing helminth infections among children.

Malaria remains a major public health problem in Papua, Indonesia, with a high incidence rate and significant hematological complications. One of the main impacts of malaria infection is anemia caused by a decrease in hemoglobin levels. This study aimed to analyze the relationship between hemoglobin levels and malaria parasite species among patients at Sentani Health Center, Jayapura Regency. This was an analytical study with a cross-sectional approach. A total of 50 malaria-positive patients confirmed by microscopic examination were included as samples. Data collected included gender, parasite species, nutritional status, hemoglobin level, and parasite count, analyzed using the Chi-Square test with a 95% confidence level (α=0.05). The results showed that most respondents were male (54%) and predominantly infected by Plasmodium falciparum (66%). The majority had normal nutritional status (40%), and the distribution between normal and abnormal hemoglobin levels was equal (50% each). Statistical analysis revealed a significant association between body mass index and hemoglobin level (p=0.03), but no significant relationship between parasite species and hemoglobin level (p=0.145). These findings indicate that nutritional status plays a more dominant role in determining hemoglobin levels than parasite species variation. In conclusion, anemia among malaria patients in endemic regions is influenced not only by the infecting Plasmodium species but also by individual nutritional factors. Integrated interventions focusing on nutritional improvement and malaria control are essential to reduce anemia risk in endemic areas such as Papua.

Adolescents are an age group that is vulnerable to reproductive health problems, including the risk of Sexually Transmitted Infections (STIs) and risky sexual behaviors, due to limited knowledge and psychosocial maturity. Schools have a strategic role in providing reproductive health education as a promotive and preventive effort. This counseling activity aimed to determine adolescents’ knowledge regarding the prevention of Sexually Transmitted Infections (STIs) among students at Parulian 3 School, Medan.This study employed a one-group pretest–posttest approach. The participants were all seventh-grade students who met the inclusion criteria. The intervention consisted of reproductive health education delivered through lectures, discussions, and visual media. Data were collected using questionnaires measuring knowledge and attitudes before and after the counseling session, and then analyzed descriptively by comparing pretest and posttest results. The results showed an increase in students’ knowledge and attitudes after receiving reproductive health education. The differences in scores before and after the intervention indicate that the counseling provided was effective in improving students’ understanding and fostering positive attitudes toward the prevention of STIs and risky sexual behaviors. Reproductive health education in the school setting is an effective effort to enhance adolescents’ knowledge and attitudes regarding reproductive health. Therefore, reproductive health education activities should be implemented continuously and integrated into school programs.

Production planning and inventory control are critical aspects of operations management, as they directly influence cost efficiency, resource utilization, and the continuity of the production process. Ineffective planning and inventory decisions may lead to excessive costs, production delays, or imbalances between supply and demand. The complexity of these problems, which often involve multi-period horizons and multi-stage decision-making processes, has encouraged the application of quantitative optimization methods, one of which is dynamic programming. This study aims to analyze and synthesize the application of dynamic programming in production planning and inventory control through a Systematic Literature Review (SLR) approach. The SLR process was conducted by systematically identifying, selecting, and analyzing 15 relevant national journal articles published between 2015 and 2024 and obtained from various recognized scientific databases. The reviewed literature indicates that dynamic programming is effective in supporting optimal decision-making by determining appropriate production quantities and inventory levels, minimizing total production and holding costs, and managing fluctuating demand conditions. In addition, this method helps reduce the risks associated with overstock and stockouts by considering sequential decision structures. However, the findings also reveal several limitations of dynamic programming, including high computational complexity, strong dependence on deterministic data assumptions, and limited flexibility in handling high levels of uncertainty. These constraints suggest the need for further methodological development or integration with other approaches to enhance practical applicability.

This study investigates the integration of computational thinking (CT) principles with adaptive curricula to enhance problem-solving skills in undergraduate programming education. Traditional programming curricula often emphasize syntax and basic concepts, neglecting critical problem-solving strategies. The adaptive curriculum framework used in this study combines CT skills such as decomposition, pattern recognition, abstraction, and algorithmic thinking with personalized learning experiences. A mixed-method approach, combining qualitative and quantitative research, was employed to assess the effectiveness of this integrated approach. The results show significant improvements in students' problem-solving abilities, conceptual understanding, and engagement compared to a control group following a traditional curriculum. Students in the experimental group, which received the adaptive curriculum, demonstrated better performance in applying algorithms and debugging code. Additionally, students expressed higher levels of engagement and motivation, suggesting that the personalized learning environment fostered greater academic involvement. The study highlights the importance of integrating CT principles with adaptive learning frameworks to create a more inclusive and effective learning environment that accommodates diverse learning needs. The findings suggest that adaptive curricula can bridge gaps in traditional education by providing personalized support and ensuring that students progress at their own pace. This approach is especially beneficial for programming education, where both conceptual understanding and practical problem-solving skills are critical for success. Future research should explore the long-term impact of adaptive learning frameworks and investigate how these technologies can be integrated with traditional teaching methods to maximize their effectiveness.
