Prediction of Malaria Incidence in Batu Bara Regency Using the Extreme Gradient Boosting (Xgboost) Method
No full textMalaria is a deadly disease transmitted through mosquitoe bites especially that of female Anopheles mosquitoes. It remains one of the world’s infectious diseases with a high mortality rate even as of today. According to data from the World Health Organization, an estimated 249 million malaria cases were recorded across 85 malaria-endemic countries globally in 2022, with Indonesia being the second-largest contributor in Southeast Asia, following India, with a total of 811,636 positive malaria cases. Meanwhile, data from Indonesia's Ministry of Health showed a 32.29% increase in malaria cases in Indonesia in 2022 compared to the previous year. Although 22 out of 33 districts in North Sumatra have been declared malaria-free, malaria cases still frequently occur in areas with difficult-to-reach geographical conditions, one of which is Batu Bara Regency. Batu Bara Regency is classified as a region with a moderate level of endemicity in North Sumatra. In addition to mobility factors, climatic factors such as temperature, humidity, rainfall, and others also significantly influence the spread of malaria. In order to support the government's national goal of eradicating malaria by 2030, there is a need for a predictive model that can accurately forecast the spread of malaria so that swift and effective interventions can be implemented. This study employs the eXtreme Gradient Boosting (XGBoost) model to predict the weekly spread of malaria in Batu Bara Regency, North Sumatra. The researcher also performed data synthesis using TimeGAN to generate data from 2015 to 2018, effectively doubling the total dataset. The most optimal model produced test results with MAE, RMSE, MSE, and R2 values of 2.712, 3.905, 15.251, and 0.806, respectively. The model parameters used include a colsample_bytree of 0.9, learning_rate of 0.1, max_depth of 5, n_estimators of 100, subsample of 0.6, and a data split ratio of 6:480 PagesSkripsi Sarjan

Evaluation and Planning of Water Supply System in Simamora Village and Sionggang Village, Baktiraja District, Humbang Hasundutan Regency
No full textClean water is an essential requirement for human life and serves as a vital natural resource. It is utilized for various daily activities, including drinking, bathing, cooking, and washing. According to the Minister of Public Works and Public Housing Regulation Number 09/PRT/M/2015 regarding the utilization of water sources, water encompasses all forms of water found in and/or originating from both surface and groundwater sources. This study aims to evaluate and plan the water supply system in Simamora Village and Sionggang Village to enhance the current water supply infrastructure. The existing water distribution system in these villages fails to reach many households, forcing residents whose homes are difficult to access to rely on river water for daily use, which may not be safe for consumption. The research was conducted using data collected through direct observations in Simamora and Sionggang Villages, located in Baktiraja District, employing
a quantitative approach. The findings indicate a pressing need for the development and planning of the water supply system in both villages, with projections extending over the next ten years. To address the challenges associated with high service demand areas, a plan for utilizing a new raw water source in Sionggang Village has been proposed, featuring a flow rate of 14.96 liters per second. Calculations reveal that the total projected water
requirement for the year 2033 will be 1.177 liters per second.113 PagesSkripsi Sarjan
