Abstract

The digitalization era is developing rapidly in Indonesia. The pandemic that occurred accelerated digital transformation in various fields. Various digital platforms were developed to support the continuity of education during the pandemic so that they could develop digital skills and improve the status of digital literacy in Indonesia. In addition to the positive impacts, there are also negative impacts from the development of digital transformation. The National Cyber and Crypto Polytechnic which focuses on information security is committed to encouraging increased digital skills and literacy in the surrounding community. Therefore, this time the National Cyber and Crypto Polytechnic located in Bogor Regency began to focus on developing digital skills and literacy among high school students or equivalent in Bogor Regency. The students' digital literacy status was first measured and then the right program or activity was determined to develop their digital skills and literacy. The digital literacy status was measured based on four pillars, Pillar 1 Digital Skill, Pillar 2 Digital Ethics, Pillar 3 Digital Safety, and Pillar 4 Digital Culture. Data collection was carried out by giving questionnaires to 276 high school students or equivalent who used the internet in Bogor Regency. Students give a score to each statement and then the score will be calculated as an average per pillar. The digital literacy index is obtained from the average score of all pillars. The digital literacy index result is 3.14 which is higher than the West Java digital literacy index of 2.78. In addition, pillar 2 Digital Ethic has the lowest score among the four pillars so that the next program is expected to aim to increase this score.

Abstract

This study discusses changes in the coalition pattern of political parties in the leadership period of President Joko Widodo who was elected in 2014 and 2019, this research uses a descriptive qualitative method with a literature/literature study approach, so the results show that in the first period the coalition pattern that was built was an ideological coalition pattern, but this pattern changed to transactional pragmatism, because the Coalition of political parties pro-president Joko Widodo's government experienced successive defeats in parliament, One of the defeats did not get a leadership seat in parliament because it lost the number of votes in parliament, so the ideological coalition pattern turned into a transactional pragmatic coalition, where President Joko Widodo attracted opposition parties, namely PPP, Golkar and PAN, to join the pro-government coalition, by sharing ministerial seats, with the aim that the government coalition could win in parliament in determining policies. In the second period of Joko Widodo's presidency, he became more pragmatic because Prabowo, who was Joko Widodo's rival, was drawn into a coalition with the government by giving Prabowo the position of Minister of Defense, so that the impact caused by democracy became unstable, because opposition parties were getting weaker and many policies in their determination were controversial, including the Job Creation Law, revision of the KPK Law, the IKN Law and the dissolution of organizations considered radical by the government.

Abstract

Pada makalah ini dijelaskan hasil-hasil Computational Fluid Dynamics (CFD) dari ruang bakar versi 1 mesin TJE500FH. Tujuan dari simulasi ini adalah untuk menyelidiki karakteristik aliran udara di dalam ruang bakar terutama terkait fenomena adanya pembakaran di luar nosel. Simulasi ruang bakar dalam makalah ini menggunakan model 3D pada kondisi dingin, tunak dan dengan kerapatan udara dianggap konstan. Model turbulensi k – ï¥ standar digunakan untuk menghitung efek turbulensi terhadap medan aliran yang dihasilkan. Dari simulasi ini, diketahui bahwa massa udara yang masuk zona primer dan zona sekunder liner lebih kecil dari rancangannya sehingga kemungkinan tercipta campuran bahan bakar – udara yang terlalu kaya di daerah tersebut. Selanjutnya, sebagian besar udara masuk liner ruang bakar pada zona dilusi sehingga alih-alih terjadi pendinginan malah terjadi reaksi pembakaran. Kurangnya udara pada zona primer dan zona sekunder tampaknya disebabkan oleh bentuk sisi-sisi luar liner yang tajam.

Abstract

The growing prevalence of cyber threats and attacks poses significant risks to the security of personal data and the integrity of sensitive information worldwide. Cryptography plays a vital role in establishing strong cybersecurity defenses, and the development of robust cryptographic algorithms is essential for protecting data against cyber-attacks. This workshop aimed to enhance participants’ understanding of the mathematical foundations of cryptographic algorithms and equip them with practical skills to identify and mitigate cyber threats. It also introduced innovative educational tools, including an Augmented Reality (AR) application for teaching classical cryptography and a Game-Based URL Phishing Education application. A total of 110 participants attended and completed the pre-test. The post-test measured knowledge gained during the workshop, and an accompanying survey gathered feedback on its effectiveness and identified areas for improvement. Overall, the workshop successfully achieved its objectives by educating participants on cryptography in the Internet of Things (IoT), increasing awareness of social engineering, introducing cryptographic tools from ancient to modern times, and exploring the principles of quantum cryptography.
