The rapid development of digital streaming platforms such as Netflix has generated a large volume of content data with diverse characteristics, thereby requiring effective analytical methods to understand emerging patterns and trends. This study aims to classify Netflix content into two main categories, namely movies and television shows, and to analyze genre trends and content characteristics using a data mining approach with the Naive Bayes algorithm. The dataset used in this study is the Netflix Shows dataset, consisting of 8,809 content entries, with the primary features analyzed including genre, rating, and country of production. The research process begins with data exploration and preprocessing stages, including data cleaning, handling missing values, and transforming categorical features to enable effective model construction. Subsequently, the dataset is divided into training and testing sets to objectively and systematically build and evaluate the Naive Bayes classification model. Model performance is evaluated using accuracy, precision, recall, and F1-score metrics to assess the model’s ability to accurately distinguish between Netflix content types. The experimental results demonstrate that the Naive Bayes algorithm is able to classify Netflix content into Movie and TV Show categories with accuracy, precision, recall, and F1-score values of 100%, respectively. The confusion matrix indicates that no misclassification occurred, suggesting that genre, rating, and country of production features provide a very clear separation between content classes. These findings indicate that the Naive Bayes algorithm can achieve exceptionally high classification performance with optimal evaluation results. The results further reveal distinct differences in characteristics between movies and television shows based on genre and production attributes. Therefore, this study is expected to contribute to the development of content recommendation systems and strategic content management within the streaming industry.

This study aims to examine the application of mocaf flour as a partial or complete substitute for wheat flour in the preparation of dadar gulung, a traditional Indonesian delicacy. The research is grounded in the potential of mocaf, which is gluten-free, rich in dietary fiber, and supports efforts to diversify food sources based on local commodities. A quantitative experimental method was employed with three flour formulations 50% wheat : 50% mocaf, 25% wheat : 75% mocaf, and 100% mocaf evaluated through organoleptic testing by 25 panelists with varying levels of experience. The assessment parameters included color, aroma, taste, texture, and overall perception. The findings indicate that the formulation containing 100% achieved the highest overall score, followed by the 75% mocaf and 25% wheat blend, while the 50% mocaf and 50% wheat formulation ranked lowest. These results suggest that a dominant proportion of mocaf can maintain the sensory quality of the product, although full substitution requires further optimization to enhance consumer acceptance. This research contributes to the development of healthier innovations in traditional foods, offers a gluten-free alternative for individuals with dietary restrictions, and promotes the sustainable utilization of local resources.

Dynamic programming (DP) is a foundational technique for solving multistage optimization problems; however, its classical formulation often incurs a cubic time complexity, rendering it impractical for large-scale real-world applications. This study proposes an accelerated dynamic programming framework that leverages quadrilateral inequality and convex monotonicity theory to significantly reduce computational overhead. By formally establishing the structural conditions under which DP decision boundaries exhibit monotone behavior, the proposed method eliminates redundant state transitions and maintains a sequence of admissible decisions through an efficient stack-based mechanism. The resulting algorithm achieves a worst-case complexity of O(n2) and can be further optimized to O(n) when convex monotonicity holds, representing a substantial improvement over traditional O (n3) techniques. Experimental validation using the classical stone-merging problem demonstrates that the accelerated method executes more than 60 times faster than the standard approach for large inputs, while maintaining identical optimal results. These findings confirm that embedding geometric regularities into DP formulations not only enhances performance but also broadens the applicability of dynamic programming to computation-intensive optimization tasks. This research contributes a mathematically grounded, scalability-oriented solution for accelerating dynamic programming, with implications for logistics, production planning, data segmentation, and other large-scale decision systems.

Oxygen is vital therapy where delivery accuracy is crucial, especially for infant patients, to ensure treatment effectiveness and prevent the risks of hypoxia or toxicity. With the implementation of the mandatory Domestic Product Utilization Policy (TKDN+BMP ≥ 40%), evaluating the quality of local products has become an urgent necessity. This study aims to test and analyze the quality and accuracy of domestically produced infant oxygen flowmeters compared to an imported product. The method used was experimental testing, measuring three brands of domestic products and one brand of foreign product at flow rate settings of 0.5, 1, 1.5, and 2 liters per minute (LPM). Each setting point was measured 10 times using a standardized calibrator to ensure data reliability. The measurement results were analyzed to identify the deviation level of each product. The findings of this study are expected to provide an objective conclusion on the quality equivalence of domestic products with imported ones and to identify which product has the lowest deviation rate. This can serve as scientific consideration for hospitals in selecting high-quality infant oxygen flowmeters, thereby supporting the domestic product policy.

Persistent elevation of blood glucose levels defines diabetes mellitus, a chronic metabolic disorder that occurs when insulin production is insufficient, diminished sensitivity of insulin receptors, or a combination of both factors. The medicinal properties of red ginger (Zingiber officinale var. rubrum) are attributed to its rich content of bioactive compounds, including gingerol and shogaol, which are considered key contributors to its various therapeutic effects. The effectiveness of red ginger extract in lowering blood glucose levels in experimental mice was evaluated in this study. A true experimental design with a quantitative approach was applied, employing a pretest–posttest control group format. The study involved twelve samples, which were randomly allocated into four separate groups. The treatment phase was conducted over a period of seven days. Findings revealed mean values of 10.4 prior to the intervention and 15.2 afterward, indicating a notable increase. A significant difference between pre-treatment and post-treatment measurements in group K1 was revealed by the statistical analysis, which yielded a P-value of 0.001 (P < 0.05). It was observed that red ginger extract, given at 100 mg per kilogram of body weight, effectively reduced blood glucose levels in the mice studied..

The puring plant (Codiaeum variegatum), which has been known as an ornamental plant, apparently has significant therapeutic potential, supported by the presence of secondary metabolites such as flavonoids, tannins, saponins and alkaloids. Various modern studies report the biological activity of croton leaves, including anti-cholesterol, anti-hyperglycemia, antibacterial effects, and their use in biosurfactant formulations. However, studies on how varying extract concentrations influence bioactivity parameters quantitatively are still limited, especially in the context of dose-response relationships involving many biological parameters in one series of research. Therefore, this research was conducted to evaluate eight bioactivity parameters, namely PSM, SSSP, DSSP, SL, RO, SM, PSL, and ANA at croton leaf extract concentrations of 1%, 2%, and 4%. This research uses a laboratory experimental approach by extracting croton leaves through a maceration method using ethanol, then formulated in three concentration levels. Each parameter was analyzed quantitatively to observe the pattern of changes in biological response to variations in the dose administered. The results showed that most of the PSM, SSSP, DSSP, SL, and PSL parameters showed an optimum response at a concentration of 2%, which indicates that there is a most effective dose point before a decrease in activity occurs at the highest concentration. In contrast, several parameters such as RO, SM, and ANA showed a more fluctuating response, even the ANA parameter gave the highest value at a concentration of 4%, indicating that certain activities require higher compound levels to be achieved. In general, the response pattern found was not linear, but instead formed an optimum curve typical of the bioactivity of plant extracts. These findings confirm that determining dosage is very important in the use of croton leaf extract, both for pharmacological purposes and for the formulation of natural ingredient-based products.

The results of the study showed that the calculated Chi-Square value on the first day (62,000) was greater than the Chi-Square table (12,591), on the second day (54,866 > 23,684), and the third day (58,117 > 32,670). Based on these results, H0 was rejected and Ha was accepted, which means there was a significant effect of oxytocin massage on the smooth production of breast milk in postpartum mothers at the Bandarharjo Community Health Center.

Cancer remains a major challenge in modern medicine due to drug resistance and the adverse effects of conventional therapies, making it one of the leading causes of death worldwide. Continuous scientific efforts aim to discover safer and more effective treatments. Owing to their structural diversity, strong bioactivity, and relatively low toxicity, natural compounds show great promise as sources of anticancer drug candidates. This article aims to explore the role of medicinal chemistry in investigating, modifying, and optimizing natural bioactive compounds to develop more effective, selective, and stable anticancer agents with improved bioavailability. A narrative review was conducted using scientific literature published between 2020 and 2025 from PubMed, ScienceDirect, Google Scholar, and ResearchGate. The findings indicate that eugenol, berberine, hesperidin, piperine, and quercetin exhibit anticancer activities through apoptosis induction, inhibition of proliferation, and antioxidant and anti-inflammatory mechanisms. Modern medicinal chemistry relies on understanding structure–activity relationships (SAR), chemical modification, and nanoparticle formulation to enhance biological performance. In addition, in silico techniques such as molecular docking and QSAR analysis are applied to study ligands and receptors and predict bioavailability improvements. The development of natural products as rational, effective, and safe anticancer drug candidates is strengthened by integrating experimental, computational, and pharmaceutical approaches.

Dairy cattle farming is a cattle breeding business specifically developed to produce large quantities of milk. Dairy cattle generally belong to the Bos taurus species, and one of the most common and productive dairy cattle breeds in Indonesia is the Holstein Friesian (FH). This study aims to evaluate how artificial insemination (AI) impacts the quantity and quality of milk produced by dairy cattle in the region, thereby contributing to improved agricultural practices and economic outcomes for dairy farmers in Indonesia. This study used a quantitative approach with a descriptive and experimental design to evaluate the effectiveness of artificial insemination (AI) on milk production in dairy cattle in Indonesia, focusing on factors influencing AI success. The results of this study indicate that artificial insemination (AI) has been proven effective in improving genetic quality and milk production in dairy cattle in Indonesia. Timely implementation of AI, especially at the peak of the estrus cycle, can increase conception rates by between 30% and 70%, with an ideal target of 65-75%. An AI program supported by inseminator training, maintained frozen semen quality, and good feed and livestock health management has a positive impact on the ideal calving interval of approximately 12 months, thereby increasing calf numbers and milk production. Artificial insemination is an effective reproductive method for increasing dairy cattle productivity through genetic improvement and controlled reproductive management. The success of an AI program depends heavily on semen quality, proper insemination techniques, livestock health management, and farmer involvement.
