Abstract

Indonesia faces persistent challenges in achieving sustainable development, particularly in harmonizing economic growth with environmental sustainability. The imbalance among economic, social, and environmental dimensions necessitates a comprehensive and reliable measurement tool to assess progress toward a green economy. The Green Economy Index (GEI), developed by the Ministry of National Development Planning (BAPPENAS), serves this function. However, limited data availability at the provincial level, such as in East Java, hampers accurate evaluation and informed policy formulation. This study aims to develop a machine learning-based predictive model for the GEI using a stacking ensemble approach that combines three powerful algorithms: XGBoost, LightGBM, and CatBoost. The model was built using relevant economic, social, and environmental indicators and evaluated on a holdout dataset to assess its predictive accuracy and generalizability. The results show that the stacking ensemble model achieved superior performance compared to the individual models, recording an RMSE of 0.0298, MAE of 0.0225, and the R² score of 0.9774. In comparison, CatBoost, XGBoost, and LightGBM individually performed with slightly lower accuracy. These findings confirm that the stacking ensemble approach is highly effective for predicting GEI values and offers a practical, data-driven solution for supporting sustainable development strategies at the regional level. The study concludes that such predictive tools can significantly enhance policy planning and monitoring of green economic growth, although further research is recommended to validate the model across other provinces.

Abstract

Hypothyroidism is a condition in which the thyroid gland is unable to produce enough hormones to meet the body's needs. This condition causes a slowed metabolism, which can lead to various symptoms such as fatigue, weight gain, dry skin, hair loss, constipation, cold intolerance, and facial puffiness. Given the widespread impact of hypothyroidism and the potential for serious complications, special attention is needed for early detection, diagnosis, and effective treatment of hypothyroidism. This literature review was conducted using journal review methods and data searches through sources such as PubMed, Google Scholar, and ScienceDirect. The search used the keywords "hypothyroidism," "hypothyroid," "thyroid gland," and "Hashimoto's thyroiditis." The results of the literature review found that the main cause of hypothyroidism is Hashimoto's thyroiditis, an autoimmune disease in which antibodies attack the thyroid gland. Hypothyroidism is diagnosed by examining elevated TSH and decreased free T4 levels, as well as anti-TPO antibody tests to detect Hashimoto's thyroiditis. Treatment for hypothyroidism generally involves administering levothyroxine, a synthetic thyroid hormone, to replace the deficient hormone and normalize metabolic function. Healthy lifestyle support, such as diet and stress management, is also important to help optimally manage this condition. In conclusion, hypothyroidism is characterized by a decrease in thyroid hormone production and preventive management is pharmacological in the form of levothyroxine, while non-pharmacological management is in the form of regulating food intake.

Abstract

The efficiency of emergency alert dissemination in highly populated and densely urban transport networks, such as Jakarta's integrated rail system, is undermined by sporadic connectivity and limited network resources. In this environment, an initial comparison of baseline Delay-Tolerant Network (DTN) routing protocols revealed that flooding-based routers, such as Epidemic, while achieving above-average delivery rates, suffered from high overhead and poor buffer utilization. This paper fills this gap by proposing the Combined Utility Router, a novel buffer management policy that overcomes the limitations of naive strategies, such as Drop-Oldest. Our approach holistically evaluates a message's value by assigning a weighted utility function based on its Time-To-Live (TTL), estimated total replicas, message size, and a user-defined priority. The router maintains high-value messages by discarding the message deemed the lowest utility score under the buffer constraint. Utility-based simulations in The ONE simulator demonstrate that applying our approach to Epidemic routing improves delivery probability, reduces average latency in high network congestion scenarios, while maintaining overhead rates. This work confirms that, in the context of developing reliable and efficient emergency communication systems for challenging urban topographies, optimizing buffer management extends beyond simply selecting the appropriate protocol.

Abstract

West Nusa Tenggara is an archipelago province with a high potential for marine resources and fisheries, allowing many inhabitants to make a living as fishermen. Some fishermen obtain their livelihood by diving with minimal or inadequate diving equipment. They are known as traditional diver fishermen. Various health risks can be experienced by them, including respiratory system health. This research aims to determine the lung function, including Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), and the FEV1/FVC ratio in traditional diver fishermen who dive using the breath-hold diving technique, as well as the characteristics of their diving activities. This research is a cross-sectional study with samples obtained through consecutive sampling techniques. The research subjects comprised 23 traditional diver fishermen in Impos Beach, Medana Sub-district, North Lombok District. A descriptive analysis was conducted on the data obtained. The research results showed that the average values of FVC and FEV1 were 3.27 L/minute and 3.004 L/minute, respectively, while the FEV1/FVC ratio obtained was 91.86%. On average, they dive 4.26 times per week, and all of them perform pressure equalization maneuvers to prevent barotrauma. Before diving, 12 subjects (52.17%) performed warm-up exercises, including stretching. After diving, none of the subjects take a hot shower, get a massage, or engage in strenuous activities. The lung function of the research subjects was normal, and they have taken preventive measures to avoid diving-related illnesses.
