Abstract

The current sales trend uses more online transaction concepts. The use of digitalization in online transactions and marketing is very important for businesses in increasing sales results to the maximum and on target. One way to increase this is by promoting on social media such as WhatsApp. Limited consumer contact makes it difficult for business actors to carry out promotions, so a database of consumer contacts is needed that can be maximized. In addition, problems in the process of sending manual messages can be overcome by using automatic message-sending actions so that promotions can be carried out automatically and quickly. The sending process is assisted by an "IF-THEN" statement and a screen that can recognize color conditions so that the automatic action can be operated on other services. The main objective of this research is to create a service that can accommodate consumer contacts by sharing contacts between business actors and being able to send messages automatically on WhatsApp by utilizing JITBIT. The results of this study prove that using JITBIT can send messages automatically on WhatsApp and can be operated on other services such as web-based applications. The results of the tests that have been carried out show that the accuracy level of JITBIT can send messages 100% with a delivery speed of 12 – 12.39 seconds/message

Abstract

The increasing utilization of IoT technology in various fields creates opportunities and risks for investigating all cybercrimes. At the same time, many research studies have concentrated on security and forensic investigations to collect digital evidence on IoT devices. However, until now, the IoT platform has not fully evolved to adjust the tools, methods, and procedures of IoT forensic investigations. The main reasons for investigators are the characteristics and infrastructure of IoT devices. For example, device number variations, heterogeneity, distribution of protocols used, data duplication, complexity, limited memory, etc. As a result, resulting is a tough challenge to identify, collect, examine, analyze, and present potential IoT digital evidence for forensic investigative processes effectively and efficiently. Indeed, there is not fully used and adapted international standard for the perfect IoT forensic investigation framework. In the research method, a literature review has been carried out by producing previous research studies that have contributed to further facing challenges. To keep the quality of the literature review, research questions (RQ) were conducted for all studies related to the IoT forensic investigation framework between 2015-2022. This research results highlight and provides a comprehensive overview of the twenty current IoT forensic investigation framework that has been proposed. Then, a summary or contribution is presented focusing on the latest research, grouping the forensic phases, and evaluating essential frameworks in the IoT forensic investigation process to obtain digital evidence. Finally, open research issues are presented for further research in developing IoT forensic investigative framework.

Abstract

Kebutuhan akses internet saat ini sangat tinggi dengan berbagai kegunaan seperti mencari informasi, artikel maupun pengetahuan terbaru. Dengan kebutuhan tinggi akan penggunaan internet di kalangan masyarakat, terutama pelajar sehingga memunculkan alternatif – alternatif agar pengguna dapat mengakses internet dengan mudah terutama ketika kondisi pandemi COVID-19. Permasalahan yang ditemukan pada PT LIBNET yang telah menggunakan dua Internet Service Provider (ISP) yaitu banyaknya permintaan yang melebihi kapasitasi dari klien menyebabkan perusahaan akan terganggu karena harus dilakukan banyak pengaturan dalam memenuhi permintaan klien tersebut. Seperti mempartisi beban trafik yang datang untuk mengatur perangkat gadget sehingga tidak terpaku pada satu ISP. Maka, supaya trafik dapat berjalan secara ideal, harus menambahkan throughput, membatasi waktu reaksi dan berupaya tidak membebani melebihi kapasitas salah satu ISP. Penggunaan teknik load balancing menjadi solusi teknologi yang sangat efektif untuk memanfaatkan internet tanpa harus terjadi ketimpangan request. Pada penelitian ini telah diimplementasikan loading balancing dalam menyelesaikan permasalahan request client dengan memakai dua buah node untuk melakukan redudansi sebagai syarat minimum suatu kluster. Sedangkan pada server memanfaatkan metode distribusi koneksi yang disebut dengan metode ECMP. Equal Cost Multi Path (ECMP) merupakan metode load balancing yang menggunakan metode per address-pair connection load balancing. Hasilnya akhirnya, ECMP memungkinkan router untuk memiliki lebih dari satu gateway untuk satu network tujuan. Karena metodenya adalah per address-pair connection, maka sistem load balancing ini adalah setiap address yang berbeda di koneksi yang berbeda akan berkemungkinan melewati gateway yang berbeda.

Abstract

Private Cloud has better advantages than other cloud services because private cloud is managed and run by the company itself so that cloud needs can be tailored to the company's needs, but allows abuse from within the company itself, as in the case study simulation of a Gojek startup company. This case occurred because of a security weakness in the system so that internal people took advantage of these weaknesses for their own benefit by leaking confidential data, acquisitions were carried out to prove and find evidence of crime, acquisitions used live acquisition techniques, namely acquisitions on an ongoing system, namely monitoring network traffic using Wireshark tools , the method in this case uses the Digital Forensics Investigating Framework (DFIF), data integrity must be properly maintained when acquiring digital evidence because to maintain the authenticity of the digital evidence obtained, then data integrity is tested on the digital evidence obtained, testing is carried out on digital evidence before and after the acquisition to see if there is a change in data integrity, the research results show that there is no change in data integrity.
