Abstract

Diabetes Mellitus (DM) is a chronic disease characterized by blood glucose (blood sugar) levels exceeding normal, i.e. blood sugar levels being equal to or more than 200 mg/dl, and fasting blood sugar levels being above or equal to 126 mg/dl. The increase in the number of people with diabetes is due to delays in detection. Utilization of machine learning in helping to establish a fast and accurate diagnosis is one of the efforts made in the health sector. One of the important steps to produce high classification accuracy is through the selection of relevant features. The problem in feature selection is dimensionality reduction, where initially all attributes are required to obtain maximum accuracy while not all features are used in the classification process. This study uses the Binary wheal Optimization Algorithm (BWOA) as a feature selection method to increase accuracy in the classification of diabetes mellitus. The use of metaheuristic algorithms is an alternative to increase computational efficiency and avoid local minimums. The BWOA algorithm reduces the 8 attributes in the dataset to the 3 best attributes that are able to represent the original dataset. The results showed that from the six classification methods tested, namely: K-NN, Naïve Bayes, Random Forest, Logistics Regression, Decision Tree, Neural Network. then the three logistic regression methods, naive Bayes and neural network are in good classification criteria based on Area Under Curve (AUC) while the calculation of the accuracy value shows an average of above 70%.  Keywords : Feature Selection, Classification, Diabetes Mellitus, Accuracy, Area Under Curve (AUC)

Abstract

Covid-19 has become a global epidemic and has spread to many countries in the world, including Indonesia. The COVID-19 pandemic is one source of uncertainty that causes financial data to fluctuate and cause data to be volatile. This outbreak had an impact on financial data, not only on the Rupiah exchange rate but also on the Jakarta Composite Index (JCI). The uncertainty of the JCI makes it difficult for investors, data managers, and business people to predict data for the future. JCI is one indicator of the capital market (stock exchange). The uncertainty of the JCI data causes the need for predictions, so that investors, data managers, and business people can make the right decisions so that they can reduce risk and optimize profits when investing. One of the factors causing the JCI's decline was sentiment caused by investor panic over the rapid spread of COVID-19 in various cities in Indonesia. This research uses Backpropagation Neural Network (BPNN) in making predictions and continues with optimization of BPNN using ensemble techniques. Historical data from the JCI used were obtained from yahoo.finance. The ensemble technique used consists of two approaches, namely combining different architectures and initial weights with the same data and combining different architectures and weights. The results of network performance using ensemble technique optimization show good performance and can outperform the individual network performance of BPNN. Keywords: prediction, JCI, Optimization, BPNN, volatile

Abstract

Transportation is one of the facilities in an area to improve accessibility or the relationship of an area because accessibility is often associated with the area. The Central Bureau of Statistics explained that the increase in motorized vehicles in 2015 - 2019 was a significant increase of 6.13%. Under the high demand for mobility, there may be barriers that impede this mobility. The problem with the vehicle used is due to engine damage. To overcome this problem, one solution is to call a tow truck. A tow truck is a vehicle that is used to tow a vehicle that has a traffic accident that is unable to move on its own. In the use of tow trucks, there are still problems experienced by customers and tow truck drivers, namely it is difficult to find the position of the customer's whereabouts with information or addresses that are not necessarily accurate for tow truck drivers and the lack of information about the nearest tow truck for customers. By using the Scrum method, this tow truck search application is designed to be able to place orders by displaying maps to find out the pick-up point, destination point, and tow truck location and can display the availability of tow trucks around the customer. Testing on this application is carried out using Black Box to obtain a percentage of eligibility results of 99.16% and System Usability Scale (SUS) gets an average value of 76.6 these results in SUS getting a grade B percentile rank score. Keywords : Tow Car, Scrum, Android, SUS, Black Box

Abstract

The need for the availability of information is currently very high, especially in the conditions of the COVID-19 pandemic, all organizational activities are carried out online. Human dependence on the role of information technology is increasing and this has consequences for long distance communication between devices, which requires users to be authenticated for access rights granted by the system. The problem that arises is the security of data travel during the authentication process, where there is the possibility of leaking account information. This is because communication is done on a public network while accessing resources that require privacy. Therefore we need a network connection that is safe and efficient. Virtual Private Network (VPN) is a network communication technology that allows you to connect to public networks safely and quickly. The VPN used in the solution to this problem is Wireguard. Wireguard is a VPN protocol built with advanced cryptography and makes it extremely fast and secure. The method used by the author in developing this system is PPDIOO which consists of, Prepare, Plan, Design, Implement, Operate, and Optimize. And also some supporting tools for the development of the system Unified Modeling Language. By using Wireguard VPN, the expected result is the security of the data sent to be more secure and can connect two remote networks privately using the public internet.Keywords : VPN, Wireguard, Mikrotik
