Abstract

Stroke s a disability main source and main disability source to lost years of disability-adjusted life. Currently the information technology development, especially the field of machine learning has an important role in early warning of various diseases, such as strokes. One of the methods used for stroke classifying is Support Vector Machine (SVM). In this study, we aim to compare several kernel functions in SVM such as linear, radial basis function(RBF), polynomial, and sigmoid for classifying stroke risk. We determine the best kernel based on accuracy, sensitivity, and specificity values. The result of this study shows that linear kernel function gives the best performance in classifying with values of classification accuracy 99.0%, specificity 100.0%, ,and sensitivity 97.0%. Those scores are the highest scores among the other kernel , that means the linear kernel function is the best method for classifying strokes risk.

Abstract

In this sophisticated digital era, humans are easier to connect to everything. Unfortunately, this convenience is often used for things that should not be, such as insulting other people through chatting. This makes cyberbullying rampant, especially body shaming and harassment which cause depression, anxiety, and lack of confidence. The aim of this research is analyzing the relationship between the frequency in using social media and the anxiety level as the impact of body shaming and harassment. The research method used in this research is quantitative research with a correlational method. The results of this study are there is no relationship between the frequency of using social media and the anxiety level for both victims of body shaming and harassment, but if viewed based on the results of the respondents it is found that the possibility of cyberbullying is due to the level of education of the perpetrators, attitudes, and behavior. Advice that can be given is the need of further research on the main factors that cause cyberbullying and advice for readers is to control attitudes and behavior while using social media.

Abstract

In facing national problems such as intolerance and ethnic and social conflicts, Indonesia needs to re-actualize the values of Pancasila, which have been proven as a unifying solution for the nation. Pancasila, as the foundation of the state and the nation's outlook on life, plays an important role in uniting the ethnic, religious, and cultural differences in Indonesia. However, in daily practice, the values of Pancasila tend to be eroded and are more present as formal symbols than behavioral guidelines, thus triggering various disputes between residents. Therefore, the purpose of this community service activity Pancasila is intended to (1) instill Pancasila values in the Pacet Village community; (2) mentor the Pacet Village youth organization as a facilitator of harmony by utilizing social media to campaign for harmony in society. This community service activity is a collaboration between the Pancasila and Citizenship Education Study Program, Surabaya State University with the Pacet Village Government, Pacet District, Mojokerto Regency, and the Mojokerto Regency Interfaith Harmony Forum. This community service activity is a Pancasila Discussion and Creative Content Creation Training for Karang Taruna Pacet Village. The method used is socialization, which provides material about Pancasila as a unifier of the nation, ending with digital content training. Through socialization activities, national insight training, discussions with religious leaders, and training for village officials, efforts to strengthen Pancasila encourage a harmonious life amidst diversity.

Abstract

Indonesia is highly vulnerable to natural disasters, particularly earthquakes, due to its location at the convergence of three major tectonic plates. Every year, various disasters occur, significantly impacting communities, especially children who are the most vulnerable group. This community service program aims to improve the earthquake disaster mitigation understanding of students at Asrama Tahfidz Al Uswah Bangil through an integrated learning method that combines theory and practice. The program includes introducing earthquake signs, self-rescue actions, as well as simulations of pre-disaster, during disaster, and post-disaster earthquake responses. The earthquake simulation provides students with hands-on experience in taking correct actions during disasters. Activities are carried out by dividing students into small groups to enhance interaction, communication, and collective understanding among them. After the material presentation, a Higher Order Thinking Skills (HOTS) based quiz is conducted to assess students' comprehension of the material presented. It is hoped that the knowledge and skills gained by students through this program will help them be more prepared and vigilant in facing potential disasters. This activity also contributes to increasing public awareness of the importance of disaster mitigation in Indonesia, with the hope that students can become change agents in their communities regarding disaster preparedness.

Abstract

As one of the world's biggest coal producers, it is essential for Indonesia to follow the trend of benchmark coal price fluctuations for any future possibilities. This study compared two methods of forecasting benchmark coal prices to evaluate the accuracy of the predictions used a nonparametric regression based on the local polynomial estimator and a parametric ARIMA method. Local polynomial analysis obtained a MAPE of 2.929278% using a CV method based on optimal bandwidth of 5.06 at order 2 with a cosine kernel, which means highly accurate forecasting accuracy. As for the ARIMA analysis, the data does not meet the assumption of normality, but forecasting is still continued with the best model ARIMA (1,2,1) model so that the MAPE is 12.6327%, which means good forecasting accuracy. Therefore in this study, the use of nonparametric regression methods using local polynomial estimators on data with non-normal distribution are more suitable to obtain accurate prediction results.

Abstract

As an archipelago country, Indonesia is a national and international route. This position makes high ship mobility which also increases the risk of ship accidents. To address this issue, based on these conditions, a prediction is required to forecast ship accidents in Indonesia for the upcoming period using an effective method. Through data forecasting, we can map the readiness of Basarnas resources in conducting search and rescue operations for ship accidents. Forecasting data for search and rescue operations in ship accidents is important because it can predict the quantity of needed search and rescue operations. These can be effective measures to reduce casualties in accidents of this type. This research uses the Fourier Series Analysis (FSA) method, which doesn’t require parametric assumption. Additionally, the FSA method can be used for data with unknown patterns. The data used is divided into training data and testing data. The training data used in this research is the number of search and rescue operations from January 2021 to December 2022, while the testing data is from January 2023 to December 2023. The analysis results of this study indicate that forecasting using the FSA method has a MAPE of 25.758%, which falls into the category of reasonable forecasting accuracy and with an optimal and a GCV of 166.586. The results of future predictions are in the form of a mathematical model that can be used by entering the time variable that you want to predict. The anticipated benefits of this research are to contribute to Basarnas’s planning and execution of search and rescue operations for shipwrecks, enrich academic literature on forecasting methodologies, and enhance public awareness of search and rescue operations in Indonesia

Abstract

As a maritime country strategically located along the world's leading transportation routes, Indonesia often faces increased ship accidents. Based on the Basarnas Statistics Book, ship accidents handled by Basarnas from 2021 to 2023 increased by 3%. This condition requires an effective forecasting method to carry out SAR operations to predict ship accidents in the Indonesian region in the future and assess the readiness and needs of Basarnas resources. This study compares the forecasting results obtained using the Singular Spectrum Analysis (SSA) and the Local Linear methods. Both methods do not require parametric assumptions. The data used in this study are divided into training data and test data. This data is secondary data obtained from the Basarnas Statistics Book. The training data in this study is the number of SAR operations from January 2021 to December 2022, while the testing data is from January 2023 to December 2023. From the analysis results, it is known that the method with the smallest MAPE is the Local Linear method with a MAPE of test data of 18.67% (good forecasting category), optimal bandwidth (h) = 4.299, and CV (h) = 231.39 where bandwidth is used to determine the level of smoothness of the estimate, while the CV (h) value is used to select the optimal bandwidth that minimizes the estimation error. At the same time, the SSA method has a MAPE of 40.27% (fair forecasting category). This shows that the Local Linear method provides a more accurate forecast of the number of SAR operations related to ship accidents in Indonesia. This research contributes to the SDGs to make Basarnas an effective and accountable institution and improve the planning and decision-making process in SAR operations through accurate forecasting research is relevant to accurate forecasting.
