Abstract

Skin health is a vital aspect as it functions as the body's primary protector from the external environment. Various skin diseases can arise due to infections, allergies, autoimmune disorders, or environmental factors, and often exhibit similar symptoms, making diagnosis difficult. Artificial intelligence technology, such as Artificial Neural Networks (ANN), offers an innovative solution for accurate diagnosis. One popular ANN method is Backpropagation, which updates network weights iteratively based on the errors produced. This research focuses on applying the Backpropagation algorithm to diagnose skin diseases based on patient symptoms. With a binary data-based system and training using Backpropagation, this system is expected to accurately map symptoms to types of skin diseases. The methodology involves problem identification , data collection (types of skin diseases and symptoms, encoded in binary), dataset and diagnosis rule formation , ANN design (input, hidden, and output layers) , and training and testing using binary data and one-hot encoding. The results indicate that the application of ANN with Backpropagation is effective in assisting the automatic diagnosis process for skin disease cases , achieving an accuracy of 90%. This demonstrates the significant potential of this method in automated medical expert systems.

Abstract

Companies need to implement sales growth forecasting strategies to create a balance between inventory and sales needs. Without this effort, an imbalance between inventory and sales can cause losses for the company, both in terms of finance and customer satisfaction. As a business entity engaged in the sale of basic necessities, Artha Water is committed to managing its business seriously in order to achieve profits and meet customer needs optimally. However, the development of consumer consumption patterns and sales growth lines at Artha Water which are fluctuating (up and down) make it quite difficult for the cooperative to balance inventory with demand for goods from consumers. By utilizing science in Artificial Neural Networks, we can predict future income using the Backpropagation Algorithm. From the previous description, the author concludes that from the results of the study with the best architecture experiments, namely 12-10-1 to predict sales growth at the Artha Water Store in 2024, it shows an accuracy result of 92%, MSE training of 0.06031588, that there is a significant difference, in other words, sales growth at the Artha Water Store will increase in 2024. With a total sales result of basic necessities at the Artha Water Store for 2024 of IDR 336,930,000.

Abstract

The production of chicken eggs in various regions of Indonesia shows significant variations over time, making it necessary to apply an appropriate predictive approach to support national food planning and distribution strategies. This study employs the ARIMA (AutoRegressive Integrated Moving Average) method to forecast regional chicken egg production based on secondary data from 2018 to 2024. The research steps include data collection, stationarity testing, model parameter determination, as well as the modeling process and result evaluation. The predictions indicate that total national chicken egg production will experience a significant increase, from 12.5 billion eggs in 2025 to 18.57 billion eggs in 2026. Provinces on the island of Java, such as East Java, Central Java, and West Java, are expected to remain the main production centers. Meanwhile, provinces in eastern Indonesia show less stable prediction results, indicating the need for improved data quality and the application of more adaptive models. Overall, the ARIMA model is considered effective for modeling short-term trends, although it has limitations in handling data with high fluctuations.

Abstract

Obesity is one of the global health issues that has seen a significant increase in recent decades. This condition is closely related to an unbalanced modern lifestyle, such as lack of physical activity, unhealthy eating patterns, and habits of smoking and alcohol consumption. This study aims to analyze the relationship between lifestyle and obesity risk, as well as to evaluate the effectiveness of the Support Vector Machine (SVM) method in predicting the level of obesity risk. The dataset used was obtained from the Kaggle platform, covering various variables such as age, gender, body mass index (BMI), eating habits, sleep patterns, and physical activity. Preprocessing was carried out through data normalization and encoding of categorical variables to ensure data readiness before being input into the model. The SVM model was trained using various training and testing data split ratios and showed a very high accuracy rate, even reaching 100% in some scenarios. These results demonstrate that SVM can effectively identify patterns in lifestyle data that contribute to obesity. Thus, the application of SVM can be a useful predictive tool for healthcare professionals in designing more accurate and efficient data-driven obesity prevention strategies.

Abstract

Poverty remains a fundamental issue and a primary focus in Indonesia's development. Conventional analysis often fails to provide an accurate picture due to the complexity of its underlying factors. This study aims to build a prediction model for poverty levels in Indonesia using the Tsukamoto fuzzy logic method, based on macroeconomic data from the Central Statistics Agency (BPS) for the years 2022 to 2024. Input variables include inflation rates, unemployment, and economic growth, with the output being the predicted poverty level in percentage. The fuzzy inference process involves fuzzification, rule base formation, fuzzy logic inference, and defuzzification. Data on the percentage of the poor population from BPS shows a decrease from 9.57% in 2022 to 9.27% in 2024. However, significant regional disparities and economic vulnerabilities persist due to global factors like inflation. Fuzzy logic, especially the Tsukamoto fuzzy method, is an adaptive approach capable of handling uncertainty and linguistic variables, while producing numerical outputs. The research results indicate that the fuzzy Tsukamoto model successfully predicts poverty levels with high accuracy, showing an average difference of less than 0.1% from actual data. This finding suggests that the Tsukamoto fuzzy method can be an effective predictive alternative in addressing socio-economic data uncertainties and supporting the formulation of more targeted policies.

Abstract

Unemployment is a complex problem that demands an analytical approach capable of handling data uncertainty. This study utilizes a fuzzy inference system to analyze unemployment rates in Indonesia, based on Central Statistics Agency (BPS) data for the 2023-2025 period. The fuzzy logic method was chosen due to its ability to handle linguistic variables and uncertainty in classifying unemployment levels. Input variables include education level, age group, and geographical area, while the output is a classification of unemployment risk (low, medium, high). The fuzzy inference process involves fuzzification, rule base formation, fuzzy logic inference, and defuzzification. BPS data indicates that the Open Unemployment Rate (TPT) experienced a consistent downward trend from 5.45% in February 2023 to 4.76% in February 2025. Nevertheless, the complexity of unemployment requires a flexible approach that can capture nuances of uncertainty, which conventional methods are unable to address. The research results show that the fuzzy inference system is capable of classifying unemployment levels with an accuracy of 87.3%. The highest unemployment rate is found in the 15-24 age group and among high school/vocational school graduates. This system can serve as a decision-making tool for the government in formulating more targeted employment policies.

Abstract

The open unemployment rate (TPT) is one of the important indicators in assessing the economic health of a region. This study aims to develop an accurate prediction model for the open unemployment rate using the backpropagation algorithm, as well as to evaluate the factors that influence the prediction. Accurate TPT prediction can help the government and policy makers in designing strategies to alleviate unemployment based on the results of the analysis of the developed model. This study aims to analyze and predict the Open Unemployment Rate (TPT) in various provinces in Indonesia in 2024 to 2026 using an artificial neural network model with the Backpropagation algorithm. Based on the test results, the 3-6-1 architecture model showed a prediction ability with 100% accuracy, while other architectures also gave very good results, with 100% accuracy for the 3-3-1 model and 97.06% for the 3-12-1 model. The TPT prediction results show that the unemployment rate is predicted to continue to increase from year to year, indicating the potential for an increase in the number of unemployed in the future. On the other hand, the accuracy analysis shows that each architecture produces different results, with the 3-6-1 architecture producing a longer time for the testing process, but still providing optimal accuracy. This finding illustrates that choosing the right architecture greatly affects the accuracy and efficiency in predicting TPT, which can be an important basis in formulating policies to eradicate unemployment in Indonesia.

Abstract

This research aims to analyze trends and allocation of Indonesia's health budget during 2010-2022 period based on state budget realization and projection data. The analysis was conducted on three main components of the health budget, namely central government expenditure through Ministries/Institutions, transfers to regions and village funds, and health financing. Based on the analysis results, the health budget experienced significant increase from IDR 29.89 trillion in 2010 to IDR 255.39 trillion in 2022, with the ratio to total state expenditure increasing from 2.9% to 9.4%. The Ministry of Health became the largest allocation recipient in the central government expenditure category, while the regional transfer component showed consistent growth through Special Allocation Fund (DAK) for Health and Operational Health Assistance (BOK). Drastic increases in health budget occurred during 2020-2022 period, caused by COVID-19 pandemic response through various special programs such as health budget reserves, earmarked General Allocation Fund (DAU), and village funds for COVID-19 response. The results of this research provide a comprehensive overview of the Indonesian government's commitment in the health sector and can serve as a basis for evaluating the effectiveness of health budget allocation in the future.

Abstract

The development of social media has had a significant impact on individual mental health. This study aims to detect mental health trends based on user activity on social media using the Naïve Bayes algorithm. The data used is sourced from the Kaggle platform and collected through web scraping techniques with keywords related to mental health and social media activity. The analysis process includes data preprocessing, classification using Naïve Bayes, and evaluation of model performance by dividing training and test data at a ratio of 60:40, 70:30, and 80:20. The results showed that the Naïve Bayes method was able to classify mental health tendencies with the highest accuracy of 75.17% at a ratio of 60:40. Precision and recall were higher for the “Troubled” category compared to the “Good” category, showing the effectiveness of the model in detecting indications of mental disorders. However, there is still a prediction imbalance that affects the overall accuracy. These findings suggest that the Naïve Bayes algorithm can be a tool in social media-based mental health early detection, which can be used by health practitioners and researchers to design more appropriate intervention strategies.
