Abstract

In today's digital era, the utilization of technology in education is essential to support the learning process. This research discusses the classification of junior high school mathematics questions using the Naïve Bayes method. The use of an automated system in question classification helps reduce time and effort in grouping questions based on topics. The Naïve Bayes method was chosen because of its simplicity and ability to process data. The results showed that Naïve Bayes with SMOTE and Math symbols achieved 69% accuracy, while without SMOTE, the accuracy was lower. Cross-validation showed that the classification without symbols attained an accuracy of 89.35%, slightly superior to the classification using symbols, which was 88.79%. This result indicates that Naïve Bayes with SMOTE is more effective. Although the difference in accuracy with or without symbols is slight 0.56%, the performance is relatively equivalent, with an accuracy of 89%.

Abstract

Distributed Denial of Service (DDoS) attacks have become an effective threat to the reliability and availability of the services of the internet in last decades. The effectiveness of utilizing Deep Neural Networks (DNNs) for DDoS attack detection is investigated in this paper. We implemented a reliable detection system that analyzes network traffic data to spot any DDoS activities. A multi-layer perceptron model trained on a dataset containing five different forms of DDoS attacks and normal traffic is used in this method. Also, three cases of varous number of features was investigated to extract the optimal number of features that can be used for detection of DDoS attacks. To improve accuracy, a great deal of testing was done on the model's architecture using various hyperparameters and training procedures. With a 96.5% detection rate, the DNN results showed a high degree of accuracy. This demonstration highlights the ability of deep neural networks to identify DDoS attacks in the midst of regular traffic. The six-category classification enhances detection granularity and facilitates the application of more specialized and successful mitigation techniques. Given the great precision attained, DNNs have the potential to be an essential part of real-time detection systems, providing a major advancement over conventional techniques.

Abstract

Public complaints are a form of public services provided by governments. Its function is to facilitate the public in submitting complaints related to public services. Public complaint channels: SMS, telephone number, email, form, and website. Based on website searches, various implementations of complaints were found in government websites. They are vary in term of number and implementation. For example, one website provides 2 channel, other website provides none. Two website provide 2 channel, but differs in attributes. Apart of this diversity, the portrait of implementing public complaints is unexplored. This research aims to map the implementation of public complaints in provincial governments in Indonesia. Official website is used as primary data. Documentation and website analysis is conducted to each websites. Keywords, such as complaints, complaints, public services, and public complaints, are used in website content analysis. The content analysis  is classified into the Gartner stage model: presence, interaction, transaction, and transformation. The results show that of the 38 provincial governments, 6 provincial governments are at the presence stage, 23 at the interaction stage, 4 at the transaction stage, and 5 provincial governments at the transformation stage.

Abstract

In order to support the national food security program, Sistem Informasi Pangan dan Gizi (SIPG) was built. This system was built by one of the government institutions tasked with food. In supporting its function, this system integrates data from internal and external institutions. Currently, not all data can be integrated into the system. The absence of policies related to reference codes and mechanisms for how data is obtained, processed, and displayed is one of the causes. To overcome this, the implementation of data governance is needed. Before doing this, it is necessary to assess the current level of data governance maturity. The assessment will provide an overview of whether the current data governance has been carried out correctly. The assessment was carried out using the Stanford Data Governance Maturity Model. Assessment results show that the current level of maturity is at level 2. While the expectation to be achieved is at level 4. To achieve the expected level of maturity, 48 recommendations are given.

Abstract

Solutions for cloud computing are growing in popularity as a means for businesses to streamline operations, save expenses and increase productivity. The benefit of cloud services is that they let customers access on-demand apps and services from a shared pool of programmable computer resources and store data offsite. Cloud computing resource allocation requires sophisticated tools and methodologies for optimal utilization. These problems include load balancing, efficient resource management and compliance with legal and regulatory requirements. The majority of businesses are switching to cloud services and advising their customers to use internet services. However, effective resource allocation is critical for improving performance and lowering costs in this area. Due to unpredictable network traffic in cloud computing, resource allocation is challenging, which causes customers to complain about application timeouts, delayed system times and higher bandwidth use during peak hours. This entails allocating resources to various users and programs, such as memory, processing power, storage, and network bandwidth. In this regard, this study compares the performance ensemble method, which is stepwise Gaussian Linear Autoregressive (SGLA), and the individual method which is autoregressive integrated moving average (ARIMA). The Matlab tool is used for simulation and evaluation of the results. The results show SGLA prediction accuracy increased to an average of 98.9%, and ARIMA prediction showed an accuracy of 75.5%. In this regard, the ensemble method performed better than individual methods using the same datasets. The study recommends the ensemble method for the prediction and allocation of resources in cloud computing.

Abstract

Otak merupakan organ yang kompleks yang bisa mengontrol pikiran, ingatan, emosi, indra peraba, kemampuan motorik, penglihatan, pernafasan, suhu dan segala sesuatu yang meregulasi tubuh kita. Gelombang tersebut hanya bisa direkam dan dilihat aktifitasnya melalui alat Elektroensefalogram (EEG). Stres adalah perasaan ketegangan emosional atau fisik. Hal tersebut datang dari segala peristiwa atau pemikiran yang membuat seseorang merasa frustrasi, marah, atau gugup. Stres adalah reaksi tubuh terhadap tantangan atau permintaan. Dalam waktu singkat, stres bisa menjadi positif, seperti saat membantu seseorang menghindari bahaya atau memenuhi tenggat waktu. Tetapi ketika stres berlangsung lama, itu dapat membahayakan kesehatannya. Stress dapat diukur dengan menggunakan kuesioner, namun penggunaan kuesioner bisa dimanipulasi. EEG dapat dikombinasikan sebagai pengukur stress seseorang. Tujuan penelitian ini untuk menganalisis parameter sinyal kuantitatif EEG pada penderita stress. Sehingga harapannya parameter ini dapat digunakan sebagai upaya pencegahan kesalahan interpretasi deteksi stress yang berakibat penurunan produktifitas seseorang. Parameter kuantitatif saat sedang stress diharapkan bisa menjadi keterbarun di dalam penelitian ini.
