F-OSFA: A Fog Level Generalizable Solution for Zero-Day DDOS Attacks Detection
The globalization and digitization of society have caused a surge in network traffic, making reliable online services essential for user trust and system functionality. However, these services face ever-increasing threats, particularly complex and well-developed Distributed Denial of Service (DDoS) attacks. Zero-day DDoS attacks, a type of DDoS attack, are especially challenging because their new and unseen nature and lack of training data render traditional Intrusion Detection and Prevention Systems (IDPS) ineffective. To tackle this, we propose the Fog-based One Solution For All (F-OSFA) system - a model with three specialized components. The first component uses a hybrid machine learning and deep learning framework that combines convolutional neural networks (CNNs) and decision trees to detect traditional DDoS attacks. The second component employs a few-shot learning module with a contractive autoencoder for zero-day attack detection. The third component is a signature-based resource usage analyzer to counter attacks mimicking normal traffic. We demonstrate the efficacy of F-OSFA on publicly available datasets and prove the scheme is generalizable and effective. F-OSFA achieves an accuracy of 99.72% on CICDDoS2019 and 99.96% on CICIDS2017. In addition, it demonstrates its efficacy in the zero-day scenario as well by achieving a 96.77% on CICDDoS2019 and 95.98% on CICIDS2017. These evaluations testify to F-OSFA as a reliable and versatile solution against ever-evolving DDoS threats
An investigation of flow-induced vibrations (FIV) during cold testing on a helical tube steam generator for a high-temperature gas-cooled reactor (HTGR)
Flow-induced vibration (FIV) is a critical phenomenon where the interaction between flowing fluid and structural elements, such as pipes or tubes, results in vibrations, which may compromise system integrity. This research aims to model and simulate the behavior of a helical tube steam generator designed for HighTemperature Gas Reactors (HTGRs), employing the latest ANSYS software licensed by BRIN. The study addresses the problem of understanding fluid flow on steam generators' vibration characteristics to improve their stability and reliability. This work analyzes the system's pressure distribution, mass flow, and vibration frequencies under cold testing and turbulent conditions. The findings of this research lie in its specific focus on identifying risks of flow-induced vibrations under non-thermal conditions, an area that is rarely studied but essential for evaluating mechanical reliability during cold testing scenarios. This approach fosters a deeper understanding of the pure impact of fluid dynamics on tube structures without the complications of thermal phenomena. The one-way FSI method with external load was chosen over system coupling because it directly maps fluid-induced forces to the structural domain without requiring repeated bidirectional convergence. This approach is computationally efficient and has been extensively validated for scenarios where fluid-to-structure interactions dominate. Results indicated a pressure drop from 16 MPa at the inlet to 15.3 MPa at the outlet. Modal analysis revealed a range of natural frequencies from 0.32 Hz to 28.35 Hz. Additionally, the calculated flow-induced shedding frequency was 39.7 Hz, while the natural frequency of the helical tube stood at 16.25 Hz. The Reynolds number (Re) and Dean number (De) were determined to be 48,921 and 50,383, respectively, confirming the presence of turbulent flow. The study highlights the risk of resonance when the natural frequency approaches the shedding frequency, which could lead to excessive vibrations and potential structural damage. These findings provide valuable insights for developing safer and more efficient steam generators.
Peran yesus kristus dan Nabi Muhammad dalam sistem peradilan Tuhan (Studi Komparasi Eskatologi Kristen dan Islam)
Yang menjadi permasalahan skripsi ini: bagaimana kedudukan Yesus Kristus dan Nabi Muhammad saw dalam sistem peradilan Tuhan; bagaimana implikasinya dari kedua ajaran itu terhadap kehidupan keberagamaan. Dalam metode penelitian, digunakan beberapa metode sebagai berikut: sumber data, data primer, yaitu Kitab suci al-Qur‟an, hadits dan Kitab Suci Injil dan buku-buku lainnya; sebagai sumber sekunder, yaitu sejumlah kepustakaan yang ada relevansinya dengan skripsi ini. Sebagai teknik pengumpulan data digunakan liberary research dengan analisis data kualitatif dan metode deskriptif dan metode komparasi. Hasil penelitian: dalam kepercayaan umat Kristiani sistem peradilan Tuhan mencerminkan suatu keadilan yang sukar dijumpai dalam keadilan di dunia. Untuk mewujudkan keadilan dalam sistem peradilan Tuhan maka yang bertindak sebagai hakim adalah Yesus Kristus sendiri dan bukan Allah Bapa. Ini mengisyaratkan bahwa dalam agama Kristen peran Yesus Kristus demikian besar menempati status sebagai Tuhan. Pada saat itu tidak ada otoritas atau kewenangan yang lebih tinggi dari Yesus Kristus. Yang diadili pada saat itu adalah semua orang mulai dari yang beragama Kristen, Islam, Budha, Hindu dan sejumlah agama-agama lain. Hukum utamanya yang diletakkan oleh Yesus Kristus dalam mengadili manusia baik dari agama Kristen maupun agama non Kristen adalah cinta kasih dan iman kepada Yesus. Di sini jelas bahwa titik tekan perspektif Kristiani adalah cinta kasih sebagai rujukan utama dalam menegakkan keadilan hukum pada saat mengadili manusia. Berbeda halnya dengan sistem kepercayaan Islam bahwa dalam sistem peradilan Tuhan nanti yang bertindak sebagai hakim tunggal dengan kata lain sebagai hakim dari segala hakim hanya Allah SWT. Sedangkan posisi Nabi Muhammad SAW hanya dapat mengajukan syafa'at, artinya memohon pertolongan kepada Allah agar manusia yang dimintakan syafa'at itu diampuni dosanya oleh Allah SWT. Hal ini berarti peranan Nabi Muhammad SAW tidak lebih hanya sebagai hamba Allah dan sangat jauh serta tidak mungkin dapat dipersamakan kedudukannya dengan Allah SWT. Sebagai persamaan antara sistem peradilan Tuhan dalam perspektif Kristen dengan pandangan Islam sebagai berikut: a) baik dalam Kristen maupun dalam Islam, peradilan Tuhan merupakan sistem peradilan yang mencerminkan keadilan. b) Yesus Kristus maupun Nabi Muhammad sama-sama mempunyai peranan untuk menolong umat manusia. Sedangkan Perbedaannya dapat disebutkan: a) posisi atau kedudukan Yesus Kristus sebagai hakim yang tertinggi, sedangkan Nabi Muhammad dalam sistem paradilan Tuhan hanya mampu memberi syafa'at; b) putusan Yesus Kristus tidak perlu ada izin dari Allah Bapa, sementara syafa'at harus ada perkenan Tuhan
Critical Discussion Between Islamization and Development of Science
The idea of Islamization of knowledge came from the anxiety of the Muslim thinkers who see the fact that almost all the forgotten history of science that most of the development of science, Islam plays an important role in the history of its development, and the state of reality that science itself has started to separate and far from Islam, departing from it all in the 1981's came around the name Islamization of science pioneered by Muhammad Naquib Al-Attas is then followed by Ismail Al-Faruqi, he suggests some prisnsip Islamization of knowledge related to this such as the rejection of any something that is not related to reality, negating the intrinsic contradictions and paradoxes protect it from unilaterally. Islamization of knowledge that is basically a scientific activity as uncover, connect and disseminate knowledge from the perspectives of the nature of human life. So Islamization of science can be regarded as an attempt liberation of the assumptions or interpretations of reality then west to replace the Islamic worldview. Islamization of science itself must have some conception of the science target pegetahuan who then proceeds to islamisas creation science. The ethics of scientific development which sometimes affects the development of science itself includes several things such as human nature, human dignity, the balance of the ecosystem, is accountable to the public interest which includes the present and future as well as universal

Sebagai aspek penting dari bisnis, pemasaran bertanggung jawab untuk mengelola hubungan pelanggan tetapi sering dikaitkan dengan praktik yang tidak etis. Sarjana telah mengeksplorasi baik teori normatif etika pemasaran dan model positif, yang meneliti perilaku aktual, untuk memahami mengapa profesional pemasaran, terlibat dalam perilaku etis atau tidak etis. Terlepas dari penelitian ini, dua ulasan sebelumnya tentang pengambilan keputusan etis dalam literatur telah menemukan kurangnya studi empiris yang secara bersamaan menyelidiki empat tahap pengakuan, penilaian, niat, dan perilaku. Makalah ini meninjau literatur tentang pengambilan keputusan etis, pemasaran industri, dan kepemimpinan etis, dan mengusulkan kerangka kerja untuk mengevaluasi pengambilan keputusan etis dalam pemasaran industri yang bertujuan untuk mengisi celah ini
SEJARAH DAN ISTILAH – ISTILAH EKONOMI ISLAM
The thought of Islamic Economics began since the Prophet Muhammad. Appointed as an Apostle (messenger of Allah), several policies carried out by the Prophet Muhammad SAW related to the implementation of community life at that time, in addition to the issue of fiqh, politics, as well as commercial or economic problems. The economic problems of the Islamic ummah at that time were of concern to the Prophet, because economic problems were the pillars of the faith that must be considered carefully for the benefit of the world and in the future. Poverty will bring people to disbelief, so efforts to eradicate poverty are parts of social policies issued by the Prophet Muhammad.The thought of Islamic Economics began since the Prophet Muhammad.

ZAKAT DALAM SEJARAH UMAT PRA-KENABIAN MUHAMMAD
Al-Qur`an dan Hadits sering menyinggung persoalanpersamaan dan perbedaan ritual antara Islam dengan Kristendan Yahudi yang sama-sama sebagai agama sah Ibrahim.Salah satu persamaan ritual tersebut adalah kewajibanmengeluarkan zakat. Dalam tulisan ini, penulis mengkajipersoalan zakat dalam syarî’ah terdahulu denganmenggunakan metode tafsir tematik. Dalam kaitan ini, al-Qur`an menampilkan kata zakah dalam tiga gaya bahasa(uslûb). Pertama, menggunakan uslûb insyâ’iy, yaitu berupaperintah, dengan menggunakan kata âtû, anfiqû, dan khuzh.Kedua, menggunakan uslûb targhîb (motivatif). Ketiga,menggunakan uslûb tarhîb (intimidasi). Keempat,menggunakan uslûb madh (pujian). Karena fokus penelitian inihanya menyangkut ayat-ayat pokok tentang zakat terdahulu,maka hanya kata-kata dalam ayat pokok itu yang dianalisisberdasarkan tiga gaya bahasa (uslûb) ini. Dalam surat Maryamayat 31, al-Qur`an menggunakan kata awshâ, dalam suratMaryam ayat 55, al-Qur`an menggunakan kata ya’muru,dalam surat al-Anbiyâ’ ayat 73, al-Qur`an menggunakangabungan kata awhâ dan îtâ’, dalam surat al-Baqarah ayat 83,al-Qur`an menggunakan kata âtû, dalam surat al-Mâ’idahayat 12, al-Qur`an menggunakan gabungan kata umirû danâtaytum. Dalam keenam ayat di atas, al-Qur`an sama-samamenggunakan gaya bahasa perintah (uslûb insyâ’î). Ini bisadibuktikan dengan konsekuensi serius bagi pengingkar zakat
Rekrutmen Karang pada Substrat Batu di Gosong Pramuka, Kepulauan Seribu DKI Jakarta
Gosong Pramuka is an area of coral reefs in the center of the Kepulauan Seribu region economy. The existence of the stony substrate around Gosong Pramuka as a potential habitat for coral larval settlement. Research aims to determine the recruitment of coral stony substrate in the Gosong Pramuka, Kepulauan Seribu. Research was conducted from April to June 2013 at Gosong Pramuka, comprising four stations: Exposed I, Exposed II, Sheltered I, and Sheltered II. Observations were conducted by observing all surface of stony substrate for coral recruits. Each coral recruits were vertically photographed using underwater camera with macro setting, thus identified until genus level. Images of coral recruit were processed by Image J to measure coral diameter and width. There were 95 colonies of coral recruits with the largest number of colony observed at Station Exposed I (35 colonies) belonging to Acropora and Porites. Lifeform of coral recruit for Acropora comprised of branching, digitate, tabulate and encrusting, while for Porites was massive and submassive. Average width of coral recruit was 25-50 cm2, while average diameter was 9-12 cm. Average index of coral health was 2-3, referring to CoralWatch method, indicating stressed colonies. Density of coral recruit for Station Exposed I was 0.22 colony/m2, Sheltered I 0.11 colony/m2, Exposed II 0.13 colony /m2 and 0.11 colony /m2 at Sheltered II. Correspondence analysis revealed that the presence of Porites coral recruit was influenced by depth, salinity, pH, temperature, while Acropora by distance from reef/stone bottom. Average diameter and width of coral recruits were closely associated with orthophosphate. Diameter of coral recruit was closely affecting the coral width
