Abstract

AbstrakSetiap lima tahun sekali kita melakukan pemilihan umum untuk menentukan calon pemimpin periodeselanjutnya. Mendekati hari dimana pemilu tersebut dilaksanakan, banyak lembaga survei berlomba –lomba menyediakan informasi mengenai pemilu. Salah satunya dengan cara membuat sistem polling. Hasilpolling yang dikeluarkan dari tiap lembaga survei pun berbeda – beda dan mengklaim bahwa hasil pollingyang mereka keluarkan merupakan yang paling akurat. Oleh karena itu, sistem polling yang akurat dancepat dengan memanfaatkan media sosial sangat dibutuhkan. Pada penelitian ini, sistem polling yangdibuat berbasis media sosial twitter, dengan memanfaatkan API untuk pengambilan data peserta polling .Dalam sistem yang dibangun, proses autentikasi terdiri dari dua tahap. Pada tahap pertama, sistemmenggunakan autentikasi API media sosial untuk menyaring bot. Sedangkan, tahap kedua menggunakanreCaptcha yang merupakan sebuah program yang dapat membedakan manusia dengan program komputeratau bot. Sistem polling yang dibangun dengan menerapkan reCaptcha sebagai autentikasi user berhasilmencegah 100% akun bot untuk mengikuti polling. 70% akun bot ditangguhkan oleh media sosial (twitter)sementara sisanya diblokir oleh reCaptcha.Kata kunci : polling, media sosial, autentikasi, API, reCaptcha, bot.AbstractEvery five years, we held general elections to determine the future leaders of the next period. Approachingthe election day, many survey institutions competed to provide information related to the elections. One ofthem is by creating a polling system. The results of the polls issued by each survey institute were differentand claimed that the poll results they issued were the most accurate. Therefore, a faster polling system withhigher accuracy by utilizing social media is required. In this study, a polling system was created based onTwitter social media, using the API for polling participants' data collection. In the developed system, theauthentication process consists of two stages. In the first stage, the system utilizes social mediaauthentication API to filter out the bots. Whereas, the second stage uses reCaptcha which is a program thatcan distinguish humans from computer programs or bots. The polling system that was built by applyingreCaptcha as user authentication was able to prevent 100% bot accounts from participating the polling.70% of bot accounts were suspended by social media (twitter) while the remaining were blocked byreCaptcha.Keywords: polling, social media, authentication, API, reCaptcha, bot.

Abstract

AbstrakArsitekstur Transmission Control Protocol (TCP) congestion control mengalami masalah kinerja yang tidak optimal. Sehingga membuat TCP dan berbagai variasinya mempunyai harapan kecil dalam mencapaikinerja yang tinggi. Penyebabnya adalah TCP menggunakan hardwired mapping yaitu suatu kejadian yangsudah diasumsikan dan tindakan yang harus dilakukan untuk mengatasi kejadian itu tanpa mengertikondisi dari jaringan secara nyata dan kinerja yang dihasilkan. Perfomance-oriented Congestion Control(PCC) merupakan arsitekstur congestion control baru yang membuat setiap pengirim mengamati tindakandan kinerja jaringan secara empiris, bertujuan mengambil tindakan yang menghasilkan kinerja tinggi.PCC melakukan percobaan dalam beberapa kasus, salah satu kasus yaitu video streaming. Prosespengujian video streaming mendapatkan data berupa throughput, delay dan packet loss. Data tersebutdibandingkan antara PCC dan TCP dengan tujuan untuk mengetahui hasil kinerja yang lebih baik. Hasildari pengujian dari setiap parameter yaitu throughput TCP adalah 1064,841 kbps dan PCC 150,825 kbps,delay dari TCP adalah 5,326 ms dan PCC 3,843 ms dan packet loss dari TCP adalah 0,905% dan PCC0,016%. Sehingga PCC memiliki kinerja yang baik dari parameter delay dan packet loss. Sedangkan TCPkinerjanya lebih baik dilihat dari parameter throughput.Kata kunci : delay, packet loss, PCC, TCP congestion control, throughput, video streaming AbstractTransmission Congestion Control (TCP) congestion control architecture experienced poor perfomance for several years. It’s make TCP variants has little hope for achieve high perfomance. The reason is TCP usedhardwired mapping that is the assumed occurrence and the actions that be taken to resolve the event withoutunderstand condition in real network and the result of perfomance. Perfomance-oriented CongestionControl (PCC) is new congestion control architecture in which each sender continuously observes theconnection between its actions and empiricially experience perfomance, enabling it to consitently adoptactions that result in high perfomance. PCC do the experiment in many cases, one of them is videostreaming. In the testing video streaming obtained data in the form of throughput, delay and packet loss. The data obtained compared between PCC and TCP with the purpose of finding out better perfomanceresults. The test results form each parameter TCP throughput is 1064,841 kbps and PCC 150,825 kbps,delay from TCP is 5,326 ms and PCC 3,843 ms and packet loss from TCP is 0,905% and PCC 0,016%. Withthat result PCC have better perfomance from delay and packet loss parameter. Whereas TCP performsbetter seen from throughput parameters.Keywords: delay, packet loss, PCC, TCP, congestion control, throughput, video streaming

Abstract

Container-based virtualization technology is currently popularly used across all cloud platforms and is predicted to continue for the next few years. The use of this container technology will make it easier and save resources used for services. Coupled with the development of the current web architecture which is increasingly being developed and used for commercial purposes, including Microservice and Monolithic. This Microservice architecture divides its services into smaller parts based on functionality. Meanwhile, Monolithic Architecture is referred to as conventional architecture because in it services become a unified whole. For this reason, a test scenario was carried out to determine the performance of the two web architectures. In this study, load testing was carried out with the number of requests 50, 100, 500, and 1000 on Microservice and Monolithic to show scalability. The results show that the Monolithic service is superior with an average CPU usage on AWS of 83% while Microservice is at 99%. CPU in Monolithic Docker Container is 92% while Microservice is 30% for each service. For Memory Usage, Microservice gets an average of 14% while for Monolithic services it is 12%. Response Time was obtained at 1497.31 ms for Microservice and 89.02 ms for Monolithic. In testing the availability by terminating/stopping the service in the Microservice service then it is reactivated and takes 2 seconds, while in the Monolithic service it takes 3 seconds to restore the service. When the service is turned off, the Microservice service can still run normally, only the dead service will experience interference, this is inversely proportional to the Monolithic service which will be completely dead when the service is turned off.

Abstract

Advanced machine learning has managed to detect IoT botnets. However, conflicts arise due to complex models and limited device resources. Our research aim is on a quantized intrusion detection system (QUIDS), an edge-based botnet detection for IoT device pairing. Using knearest neighbor (KNN) within QUIDS, we incorporate quantization, random sampling (RS), and feature selection (FS). Initially, we simulated a botnet attack, devised countermeasures via a sequence diagram, and then utilized a Kaggle botnet attack dataset. Our novel approach includes RS, FS, and 16-bit quantization, optimizing each step empirically. The test results show that employing a mean decrease in impurity (MDI) by FS reduces features from 115 to 30. Despite a slight accuracy drop in KNN due to RS, FS, and quantization sustain performance. Testing our model revealed 1200 RS samples as optimal, maintaining performance while reducing features. Quantization to 16-bit doesn’t alter feature value distribution. Implementing QUIDS increased the compression ratio (CR) to 175×, surpassing RS+FS threefold and RS by 13 times. This novel method emerges as the most efficient in CR.

Abstract

As digital technologies increasingly permeate the education sector, the need to safeguard sensitive personal data within early childhood education systems becomes paramount. In Indonesia, where the adoption of digital tools in education is rapidly expanding, these systems are particularly vulnerable due to the hybrid nature of their processes, varying levels of digital literacy among stakeholders, and a complex regulatory environment. This research addresses the challenge of securing Indonesia’s early childhood education systems by designing a minimized attack surface through the integration of ISO 27005-based risk assessment and the TOGAF enterprise architecture framework. ISO 27005 provides a systematic methodology for identifying, assessing, and mitigating information security risks, ensuring compliance with the Indonesian Personal Data Protection Law (UUPDP). TOGAF is utilized to structure the enterprise architecture, aligning IT strategies with institutional goals while embedding robust security measures across the digital infrastructure. The research methodology involves identifying critical assets and potential threats, evaluating these threats using ISO 27005, and developing a secure architecture tailored to the unique needs of Indonesian early childhood education systems. The proposed framework is validated through application in a case study involving several Indonesian early childhood education institutions. This approach not only enhances the security posture of these institutions but also aligns with cultural and regulatory considerations, offering a comprehensive solution for protecting vulnerable educational environments in Indonesia.
