Abstract

Penggunaan teknologi Wi-Fi yang meningkat seiring berjalanannya waktu menimbulkan keresahan dikarenakan masalah keamanan jaringan yang masih mendapat sedikit perhatian. Kota Yogyakarta sebagai penyandang kota dengan indeks literasi digital tertinggi dan perencanaan program smart city-nya belum ada jaminan keamanan terkait permasalahan ini. Penelitian ini ditunjukan untuk mengkaji tingkat keamanan jaringan home Wi Fi terhadap password attack untuk keperluan data statistik dan bahan edukasi. Metode pengambilan sampel yang digunakan yaitu teknik quota sampling dan penetration testing sebagai metode pengumpulan datanya. Hasil penelitian menunjukan serangan WPA cracking dan WPS cracking berhasil mendapatkan sebagian kecil akses login berupa password serta mengukur persentase keamanan tingkat kota maupun di setiap kecamatannya. Selain data serangan, terdapat beberapa rekomendasi untuk melindungi access point supaya terhindar dari serangan tersebut. Kata kunci: Wi-Fi, password attack, WPA cracking, WPS cracking -------------------------------------------------------------------------------------------------- The Security Level Of Home Wi-Fi Networks Against Password Attacks The escalating use of Wi-Fi technology has raised concerns due to network security issues that often receive inadequate attention. Despite Yogyakarta's status as a city with the highest digital literacy index and its smart city program initiatives, there is no guaranteed security regarding these problems. This research aims to assess the security level of home Wi-Fi networks against password attacks for statistical data and educational purposes. The sampling method employed was quota sampling, with penetration testing used as the data collection method. The research results indicate that WPA cracking and WPS cracking attacks successfully obtained a small portion of login credentials in the form of passwords, and measured the percentage of security levels at the city level and in each sub-district. In addition to the attack data, several recommendations are provided to protect access points from these attacks. Keywords: Wi-Fi, password attack, WPA cracking, WPS cracking

Abstract

Dalam era digital yang semakin berkembang, tata kelola teknologi informasi (TI) memiliki peran krusial dalam mendukung efektivitas operasional dan strategis suatu organisasi, termasuk lembaga pendidikan Islam seperti pondok pesantren. Penelitian ini bertujuan untuk mengevaluasi tingkat kematangan keamanan teknologi informasi di 21 pondok pesantren di Kabupaten Situbondo dengan menggunakan Indeks KAMI versi 5.0 yang berbasis pada standar SNI ISO/IEC 27001:2022. Metode penelitian yang digunakan adalah kualitatif. Data dikumpulkan melalui penyebaran kuesioner serta verifikasi kuesioner yang mencakup tujuh area utama indeks keamanan informasi (KAMI) dan satu area suplemen. Hasil penelitian menunjukkan bahwa sebagian besar pondok pesantren berada pada tingkat kematangan I dan I+, yang menandakan bahwa pengelolaan keamanan teknologi informasi masih dilakukan secara informal dan belum terdokumentasi dengan baik. Beberapa aspek penting, seperti manajemen risiko, perlindungan data pribadi, serta pengelolaan aset informasi, belum diimplementasikan secara optimal. Selain itu, keterlibatan pihak ketiga dalam mendukung pengelolaan sistem informasi masih sangat terbatas. Dengan demikian, dapat disimpulkan bahwa tingkat kesiapan keamanan teknologi informasi di pondok pesantren Kabupaten Situbondo masih rendah sehingga diperlukan intervensi strategis melalui kebijakan, peningkatan kapasitas sumber daya manusia, serta kerja sama eksternal untuk mencapai minimal tingkat kematangan Level III+.

This study aims to evaluate the maturity level of information technology security in 21 Islamic boarding schools in Situbondo Regency using the KAMI Index version 5.0, which is based on the SNI ISO/IEC 27001:2022 standard. A qualitative research method was employed, with data collected through questionnaires and their verification, covering seven main areas of the KAMI information security index and one supplementary area. The findings reveal that most Islamic boarding schools are at maturity levels I and I+, indicating that information technology security management is still carried out informally and has not been properly documented. Key aspects such as risk management, personal data protection, and information asset management have not yet been optimally implemented. Furthermore, third-party involvement in supporting information system management remains very limited. Therefore, it can be concluded that the readiness level of information technology security in Situbondo’s Islamic boarding schools is still low, requiring strategic interventions through policy development, capacity building of human resources, and external collaboration to achieve at least maturity level III+.

Abstract

The development of information technology worldwide has changed very rapidly. There has been a data theft on the information system belonging to one of the most prominent Islamic Boarding Schools in the Yogyakarta area. Thus, special attention is needed to evaluate information technology security using the Information Security Index version 4.2. The research methods include extracting information, literature study, data collection, data validation, data analysis, and recommendations. The evaluation results are at the basic framework fulfilment level with a value of 343; the electronic system category has a low status with a value of 15 and 5 improvements; the governance category,  the risk management category,  the framework category,  the asset management category, and the information security technology category, have a maturity level II status with 12, five, eight, four, and eight recommendations respectively, while the supplement category for third party security areas with a value of 60%, securing cloud infrastructure services 56% and protecting personal data 61% with 14 recommendations.

Abstract

Yogyakarta is listed as the region with the highest number of residents engaging in e-commerce transactions. A total of 10.2% of the population are active e-commerce sellers, while 16.7% belong to the buyer category. Research by IDN Times showed that e-commerce application users have been dominated by students, with a percentage of 44.2%.  The purpose of this study is to analyze the factors that influence students’ level of acceptance of e-commerce applications in Yogyakarta using the modified UTAUT 2. This is quantitative research with multiple linear regression models using SPSS software version 25 with a sample size of 303 people. Data analysis in this study was conducted in a few steps, including descriptive analysis, validity test, reliability test, classical assumption test and hypothesis testing. The results of this study indicate that the student’s level of acceptance of e-commerce applications is within good criteria. The variables that have a positive effect on the behaviour intention (BI) are performance expectancy (PE), effort expectancy (EE), social influence (SI), facilitating conditions (FC), hedonic motivation (HM), habit (HB), price value (PV), perceived risk (PR), perceived security (PS), and trust (TR) are variables that negatively affect the variable behaviour intention (BI). All independent variables affect the dependent variable or behaviour intention (BI) with a total of 63.3% and the difference with a total of 36.7% is caused by other factors not examined by the researcher.

Abstract

Today’s most common Positioning System applied is the Global Positioning System (GPS). Positioning System is considered accurate when outdoors, but it becomes a problem when indoors making it difficult to read the GPS signal. Many academics are actively working on indoor positioning solutions to address GPS's drawbacks. Because WiFi Access Point signals are frequently employed in multiple studies, they are used as research material. This study compares the classification algorithms KNN, SVM, Random Forest, and C 4.5 to see which algorithm provides more accurate calculations. The fingerprinting method was employed in the process of collecting signal strength data in each room of the Terpadu Laboratory Building at UIN Sunan Kalijaga using 30 rooms and a total dataset of 5,977 data. The data is utilized to run experiments to determine the location using various methods. According to the experimental data, the Random Forest algorithm achieves an accuracy rate of 83%, C4.5 81%, and KNN 80%, while the SVM method achieves the lowest accuracy rate of 57%.
