Abstract

In this paper researcher is trying to make an android-based application that can identify fish with formalin with previous version with adding some more data training. The method used in researcher methods naïve Bayes classifier as a detector (detector) with the object input in the form of fish eye image. The steps in the study include the training and testing process. In the training process used to build the model naïve classifier and estimation parameters. While testing process, implement the results of the model and parameter estimation have been built to detect fish formalin or not formalin. The trial results demonstrate the ability-based applications using the naïve Bayes 98.3% for object dimensions 10x10 image

Abstract

Information security is a crucial aspect in today's digital era, where increased connectivity and data exchange involves a high risk of denial of services attacks. Increasing cybersecurity and privacy issues require more effective defense mechanisms to counter these threats. This research was conducted through design formulation using game theory for denial of service attacks. First scheme , use Bayes' theorem to determine the probability of a DDoS attack. The probability is equal. The probability of attack and defense is 50-50. Second scheme, one of players is dominan. A game theoretic framework as an approach to find out the possibility of denial of services between pairs of attacking/defending nodes using a Bayesian formulation. Game modeling can propose for developing better mitigation and detection approaches.

Abstract

Triple DES (Triple Data Encryption Standard) merupakan salah satu algoritma simetris pada kriptografi yang digunakan untuk mengamankan data berupa pesan teks dengan cara menyandikan pesan teks. Proses yang dilakukan dalam penyandian datanya, yaitu proses enkripsi dan proses dekripsi. Algoritma triple DES adalah suatu algoritma pengembangan dari algoritma DES (Data Encryption Standard). Perbedaan DES dengan triple DES terletak pada panjangnya kunci yang digunakan. Pada DES menggunakan satu kunci yang panjangnya 56- bit, sedangkan pada triple DES menggunakan tiga kunci yang panjangnya 168-bit (masing- masing panjangnya 56 bit). Pada penelitian ini penggunaan enkripsi 3Des akan dikombinasikan dengan Base64 untuk mengamankan informasi berupa teks dengan Bahasa pemograman Python

Abstract

The study of surface wind characteristics in the airport area is needed to support flight operations in terms of safety and economy. Surface wind data is required during the aircraft take-off and landing phases. The information on surface wind characteristics is used for flight operational planning or the construction and expansion of an airport runway. To be able to know the description of the monthly surface wind profile in the airport area, the frequency distribution method is very appropriate to use. Research on surface wind patterns with the frequency distribution method in the Soekarno-Hatta Airport area over the past ten-year period shows that January - April the surface wind direction is dominated from the west, May - September is dominated from the east. The months of October, November, and December are a transition from the east to return to the west which is dominated from the south and southwest. This is in line with the general pattern of Indonesia's climate which is influenced by the west monsoon and east monsoon phenomena.

Abstract

Studi pada penelitian ini merupakan perbandingan penerapan Advanced Encryption Standard (AES) pada database Rumah Sakit Dr.Mintoharjo. Berawal dari kasus peretasan pada website Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan bpjs-kesehatan.go.id diduga diretas sekitar akhir Mei 2021 mengakibatkan, data milik 279 juta penduduk Indonesia dikatakan telah bocor dan dijual di Raid Forums, penulis menawarkan metode penyimpanan baru yang lebih aman dibandingkan dengan teknik penyimpanan biasa bagi divisi teknologi informasi. Metode Advance Encryption Standard (AES) yang diperbandingkan disini diimplementasikan pada MYSQL. Saat system informasi manajemen Rumah Sakit Dr.Mintoharjo diimplementasikan pada MYSQL dilakukan pengujian perbandingan tingkat keamanan dengan metode enkripsi Advanced Encryption Standard (AES). Hasil percobaan penelitian ini menunjukkan hasil keamanan yang meningkat dilihat dari sudut pandang efisiensi. Kesimpulan pada penelitian ini menunjukkan, metode penyimpanan yang diteliti meningkatkan system keamanan maka sangat dianjurkan mengimplementasikannya pada Rumah Sakit Dr. Mintoharjo.

Abstract

Peran internet dalam mendukung berbagai aspek kehidupan di era digital menjadi sangat krusial. Hal tersebut menjadi alasan kuat untuk memperhatikan kecepatan internet dan keamanan siber. Meski begitu, kesenjangan antara kecepatan internet dengan keamanan siber di Indonesia masih ada. Minimnya pemerataan pembangunan wilayah membuat sebagian besar wilayah Indonesia memiliki keterbatasan kecepatan internet dan persepsi kemanan siber yang rendah . Penelitian dilakukan untuk menyajikan analisis mendalam tentang urgensi peningkatan kecepatan internet seiring dengan penguatan upaya perlindungan terhadap keamanan siber, serta implikasinya terhadap masyarakat Indonesia yang semakin terhubung secara digital. Metode penelitian yang digunakan adalah regresi linear untuk menganalisis hubungan sebab-akibat antara kecepatan internet dan GCI ranking. Hasil penelitian memperlihatkan bahwa kecepatan internet (dinyatakan dalam Mbps) mempengaruhi perubahan Global Cybersecurity Index (GCI) ranking sebesar 12,7%.
