Abstract

Blockchain and cryptocurrencies have changed the way we transact and interact in the digital age. However, the rapid advancement of these technologies has resulted in major environmental impacts. Efficient implementation of blockchain requires the use of large amounts of energy and computing power, with consensus algorithms as the foundation. The purpose of this study is to investigate the environmental implications of blockchain and cryptocurrency implementation, as well as initiatives to mitigate these issues. The type of research is a library study (library research) using a qualitative method, namely by combining, collecting information or previous scientific papers on relevant topics. Along with the growing popularity of cryptocurrencies, the continuous mining process often results in large energy consumption and carbon emissions, sparking concerns about their long-term viability and environmental impact. Based on the results of previous research and research sources, the author found a solution to the problem of high energy consumption from the use of blockchain, namely: Proof of Stake (PoS), Proof of Authority (PoA), Sidechains and Layer-2 Solutions, Hardware Optimization, Implementation of Consensus Algorithms Based on RUST.

Abstract

This research was conducted to measure user experience on the OYO hotel booking application. User experience was measured by the meCUE 2.0 method which uses a Likert scale of 7. Then there are 10 instruments consisting of usefullness, usability, visual aesthetics, status, commitment, positive emotions, negative emotions, product loyalty, intention to use, and overall evaluation. The tool for processing survey data is the meCUE questionnaire which aims to see the possibility of a comprehensive end-user rapid assessment. Questionnaire links are distributed online and are needed in retrieving survey data. After collecting survey data, the measurement results obtained from 10 instruments were 5.20 (usefullness), 5.67 (usability), 5.33 (visual aesthetics), 4.27 (status), 2.90 (commitment), 4 .66 (positive emotions), 2.66 (negative emotions), 3.58 (product loyalty), 3.85 (intention to use) and 3.33 (overall evaluation). The results are considered quite good overall.

Abstract

UD. Lumban Gaol adalah perusahaan yang menjual pupuk dan peralatan pertanian. Perusahaan ini menghadapi masalah seperti tidak ada data persediaan yang jelas karena mereka menghitung secara manual. Pelanggan harus memeriksa stok di gudang sebelum membeli. Proses pengadaan barang juga kurang teratur karena catatan pembelian sering hilang, dan tidak ada tempat khusus untuk menyimpan data pemasok. Untuk mengatasi masalah ini, perlu dibuat sistem informasi untuk penjualan, pembelian, dan inventaris. Metodologi yang digunakan adalah Siklus Hidup Pengembangan Sistem (SDLC), dengan input menggunakan Microsoft Visual Studio 2015, output berdasarkan Crystal Report, dan basis data menggunakan Microsoft SQL Server 2014. Rancangan sistem ini diharapkan dapat memberikan solusi berupa keakuratan perhitungan barang dan pencatatan setiap transaksi dengan baik.

Abstract

Rantai pasok kopi Indonesia menghadapi tantangan krusial dalam hal transparansi dan keterlacakan yang berdampak pada daya saing. Teknologi blockchain menawarkan solusi potensial untuk mengatasi masalah ini. Penelitian ini bertujuan menganalisis secara kualitatif potensi dan kelayakan implementasi Hyperledger Fabric pada rantai pasok kopi di Indonesia. Menggunakan metode tinjauan literatur sistematis terhadap 30 jurnal ilmiah (2022-2025), studi ini menemukan bahwa arsitektur blockchain berizin (permissioned) pada Hyperledger Fabric merupakan solusi paling unggul. Platform ini terbukti mampu meningkatkan keterlacakan, keamanan data, dan kepercayaan pemangku kepentingan secara signifikan. Dibandingkan dengan VeChain yang berfokus pada integrasi teknologi Internet of Things (IoT), Hyperledger Fabric lebih unggul dalam aspek tata kelola (governance) dan privasi data, menjadikannya pilihan ideal untuk konsorsium rantai pasok kopi swasta di Indonesia. Implementasinya dapat mengatasi asimetri informasi dan manipulasi data secara efektif.

Abstract

This study aims to analyze the role of blockchain technology in enhancing the efficiency and security of business transactions. Blockchain, as a decentralized, transparent, and immutable digital ledger system, provides solutions to various weaknesses of conventional systems, such as high transaction costs, operational inefficiencies, and risks of data manipulation. The research method employed is a literature review that examines scientific publications, articles, and reports on blockchain implementation in business sectors, particularly banking and accounting. The findings indicate that blockchain adoption can reduce transaction costs and processing time, improve transparency, and strengthen data integrity through consensus mechanisms and smart contracts. Moreover, blockchain has the potential to create new, accountable, and trustworthy business ecosystems. However, challenges related to regulation, technological adoption, and vulnerabilities to certain types of attacks remain to be addressed. Overall, blockchain significantly contributes to achieving efficiency and security in business transactions in the digital era.

Abstract

Abstrak. Transformasi layanan publik di Indonesia melalui adopsi teknologi smart contract berbasis blockchain menawarkan peluang besar dalam meningkatkan efisiensi, transparansi, dan akuntabilitas tata kelola pemerintahan. Penelitian ini bertujuan untuk menganalisis secara sistematis tantangan dan peluang implementasi smart contract di sektor publik Indonesia. Metode yang digunakan adalah tinjauan literatur sistematis dengan pendekatan deskriptif-analitis, melibatkan penelusuran basis data akademik dan analisis isi berdasarkan tema utama. Hasil kajian menunjukkan bahwa smart contract mampu mengotomatisasi proses administrasi, memperkuat integritas data, dan mendorong partisipasi publik. Namun, implementasi teknologi ini masih menghadapi kendala berupa ketidakpastian regulasi, keterbatasan infrastruktur digital, risiko keamanan, serta rendahnya literasi digital di lingkungan pemerintah dan masyarakat. Studi ini menekankan pentingnya penguatan regulasi, kolaborasi lintas sektor, dan edukasi berkelanjutan untuk mendukung adopsi smart contract secara optimal dalam layanan publik Indonesia. Kata Kunci: Smart Contract, Blockchain, Layanan Publik.

Abstract

This study aims to systematically review the literature that explores the relationship between blockchain technology and economic value, focusing on three main dimensions: financial efficiency, financial inclusion, and systemic risk. The systematic literature review method was employed to identify, evaluate, and synthesize findings from various academic studies and relevant industry reports. The review process involved analyzing articles obtained from scientific databases such as Scopus and Google Scholar, published between 2020 and 2025. The results indicate that the implementation of blockchain technology has significant potential to enhance financial efficiency through transaction cost reduction, increased transparency, and faster settlement processes across financial systems. Furthermore, blockchain can promote financial inclusion by providing access to financial services for populations previously excluded from the conventional financial system. However, the study also reveals that blockchain adoption poses potential systemic risks, including market instability, cybersecurity vulnerabilities, and complex regulatory challenges. Therefore, the findings emphasize the importance of developing balanced policies and regulatory frameworks to maximize the economic benefits of blockchain technology while minimizing its potential risks.
