Abstract

The digital era has changed the way we interact, conduct transactions, and store data. However, the security challenges related to data and transactions are now becoming more pressing. Cybercrime becoming increasingly sophisticated threatens the integrity and trust in digital systems. Blockchain technology, which is decentralized and records transactions permanently and transparently, has emerged as a promising solution. This article will discuss the potential of blockchain in enhancing data and transaction security in the future. We will review how blockchain builds a secure system with distributed and encrypted data, making it difficult to alter or hack. This technology supports verified and tamper-proof transactions, which in turn reduces the risk of fraud and increases trust in the financial system. Blockchain is considered an important step in protecting digital infrastructure and sensitive information. With features of decentralization, transparency, and strong cryptography, blockchain offers a high level of security that is difficult to manipulate. This article reviews the potential of blockchain in enhancing data and transaction security, as well as the challenges that need to be addressed. It was found that blockchain provides high-level security through decentralization, transparency, and strong cryptography. In addition, blockchain offers efficiency, automation through smart contracts, and the potential for widespread application across various sectors. Although there are limitations and challenges, collaborative efforts and continuous innovation can strengthen the role of blockchain in securing data and transactions in the future. It is hoped that this article provides a deeper understanding of the role of blockchain in addressing current and future digital security challenges, as well as how this technology can help create a safer and more trustworthy digital environment.

Abstract: One of the IT applications utilized by the community is Microsoft Office. This application helps various parties in supporting the learning process in schools and is used by various parties for office work needs in processing words, numbers and presentations. Understanding and mastering this application is a basic ability that must be owned by every individual in the present. As is the case with students at SMA Letjen Haryono MT while studying at school. However, the use of Office has not been maximized by them. They were only introduced to Microsoft Office applications but did not understand how to use them. Therefore, students need to be equipped with additional learning that focuses on using Microsoft Office as a medium to assist student learning and also prepares students to take advantage of this application in the future. The features available in Microsoft Word, Microsoft Excel, and Microsoft Power Point are also less known by students. Departing from this, it is necessary to equip students with learning about Microsoft Office applications. Learning activities provide a range of 77% through questionnaires filled out by students which means that the training provided provides good knowledge benefits to the 28 students who take part in the training. The target planned by the implementation team was achieved where students were assisted in understanding and learning to use Microsoft Word, Microsoft Excel and Microsoft Power Point applications.           Keywords: education; information technology; microsoft office Abstrak: Salah satu penerapan TI yang dimanfaatkan oleh masyarakat adalah Microsoft Office. Aplikasi ini membantu berbagai pihak dalam mendukung proses pembelajaran di sekolah serta dimanfaatkan berbagai pihak untuk kebutuhan pekerjaan kantoran dalam pengolahan kata, angka serta presentasi. Pemahaman dan penguasaan aplikasi ini merupakan kemampuan dasar yang wajib dimiliki oleh tiap individu di masa sekarang. Seperti halnya dengan murid-murid di SMA Letjen Haryono MT selama belajar di sekolah. Tetapi, penggunaan Office belum dimaksimalkan oleh mereka. Mereka hanya diperkenalkan aplikasi Microsoft Office tetapi kurang memahami cara penggunaannya. Oleh karena itu, maka murid perlu dibekali dengan pembelajaran tambahan yang berfokus pada penggunaan Microsoft Office sebagai media untuk membantu pembelajaran murid dan juga mempersiapkan murid manfaatkan aplikasi ini di masa mendatang. Fitur-fitur yang tersedia di Microsoft Word, Microsoft Excel, dan Microsoft Power Point juga kurang diketahui oleh murid-murid. Berangkat dari hal tersebut, maka perlu melengkapi murid dengan pembelajaran akan aplikasi Microsoft Office. Kegiatan pembelajaran memberikan nilai range 77% lewat kuesioner yang diisi murid yang berarti pelatihan yang diberikan memberikan manfaat pengetahuan yang baik kepada 28 murid yang mengikuti pelatihan. Target yang direncanakan tim pelaksana tercapai di mana murid-murid terbantu dalam memahami dan mempelajari penggunaan aplikasi Microsoft Word, Microsoft Excel, dan Microsoft Power Point.Kata kunci: pendidikan; teknologi informasi; microsoft office

Abstract

Cacti Life merupakan UMKM milenial yang melihat peluang bisnis dalam konsep tanaman hias terrarium (media transparan), namun dalam kegiatan operasionalnya belum memiliki rencana pengembangan sistem informasi terpusat untuk pemasaran dan promosi, yang saat ini hanya mengandalkan e-commerce (seperti Shopee) dan media sosial (Instagram, Facebook). Selain itu, komunikasi dengan pelanggan terbatas hanya melalui kontak di media sosial , dan belum tersedianya media untuk mengimplementasikan hasil portofolio perencanaan strategi sistem informasi yang telah dihasilkan. Solusi untuk mengatasi masalah ini adalah dengan mengembangkan sebuah website yang dapat digunakan secara efektif untuk kegiatan pemasaran dan promosi, sekaligus mengimplementasikan perencanaan strategi sistem informasi. Pengembangan website ini menggunakan metode User-Centered Design (UCD), yang melibatkan tahapan identifikasi masalah, penentuan konteks dan persyaratan penggunaan, pengembangan desain solusi menggunakan React Js, Express Js, dan PostgreSQL, serta evaluasi desain melalui pengujian prototipe dan card sorting. Hasilnya adalah terwujudnya website dengan fungsionalitas lengkap untuk administrasi (pengelolaan produk, event, pesanan, dan lain-lain.) dan pelanggan (pemesanan produk atau layanan, melihat informasi). Diharapkan website yang dibangun, didukung strategi pemasaran digital, dapat meningkatkan visibilitas, pemasaran, promosi, dan pada akhirnya, pendapatan Cacti Life.

Abstract

PT Yorgo Anugerah Nusantara is a palm oil company with 510 employees whose leave, permit, overtime, and business-trip requests are handled entirely through paper forms. Each submission requires a physical handover from the employee to the Head of Department for approval, then to HRD for recording, resulting in delays of more than one working day per cycle and errors in documentation. This study develops a mobile-based employee request administration system that digitises those four workflows. The system is built using the Rapid Application Development (RAD) methodology, implemented with the .NET MAUI cross-platform framework, ASP.NET Core Web API, and PostgreSQL. System modelling used Use Case Diagrams and Activity Diagrams to capture both the current and proposed processes, and an Entity Relationship Diagram for data structure design. Functional validation applied Black Box Testing with the Equivalence Class Partitioning technique, all of which returned valid results. The system successfully replaces paper-based workflows with a digital end-to-end approval chain, enables real-time tracking of request status, and enforces automatic validation rules including a two-hour cap on permit duration, time-logic checks for overtime, and mandatory document attachment for sick leave.

Abstract

The background of this study is based on the challenges currently being faced by the Indonesian financial sector in terms of transparency and trust. Various cases that often occur such as data manipulation, fraud, and lack of accountability in the financial transaction process have drastically reduced public trust in financial institutions. Blockchain technology here is present as one of the potential solutions to overcome this problem, by offering a decentralized, transparent, and immutable financial recording system. This study aims to analyze the implementation of blockchain technology in increasing transparency and trust in the Indonesian financial sector. The research method used is qualitative with the Systematic Literature Review (SLR) approach. This research was conducted by collecting and analyzing relevant literature related to the implementation of blockchain in the financial sector, especially in Indonesia. The analysis process was carried out using the content analysis method in order to identify the benefits, challenges, and impacts of blockchain implementation on transparency and public trust. The results of the study show that blockchain has great potential in increasing transparency in the financial sector, by reducing the risk of data manipulation and increasing operational efficiency. However, several challenges are still faced, such as inadequate regulations, uneven technological infrastructure, and low digital literacy in the community. This study emphasizes the need for collaboration between the government, financial institutions, and the community to create an ecosystem that supports the widespread adoption of blockchain technology. With a collaborative approach, blockchain is expected to contribute significantly to strengthening a more transparent, accountable, and highly competitive financial ecosystem in the future. In addition, this study provides an understanding of the readiness of the Indonesian financial sector in facing technological changes and innovation opportunities in the future.
