Abstract

The rapid advancement of blockchain technology and the emergence of the metaverse as a cross-border digital economy have triggered new legal challenges, particularly concerning smart contracts and virtual property disputes. Smart contracts—self-executing agreements coded on blockchain—offer efficiency and transparency but raise critical questions about legal validity, jurisdiction, and dispute resolution when conflicts arise between parties from different countries. In the context of virtual ownership such as digital land, NFTs, and in-world assets, diverging national legal systems complicate the enforcement of rights over virtual property. This study analyzes how smart contracts are utilized in virtual property transactions and examines the evolving international legal approaches to disputes arising from such agreements. The research highlights the urgent need for an adaptive global legal framework, cross-jurisdictional recognition of digital rights, and the role of blockchain-based arbitration bodies as alternatives to traditional dispute resolution. It also explores the relevance of traditional contract law principles in decentralized virtual environments and the regulatory challenges related to digital identity and evidentiary standards. With a multidisciplinary approach, this abstract offers insights into the importance of legal harmonization and international collaboration in supporting a fair, predictable, and legally secure metaverse ecosystem.

Abstract

This study identifies and reduces waste in the cooking oil production process at PT X by integrating Lean Six Sigma with Value Stream Analysis Tools (VALSAT) and Failure Mode and Effects Analysis (FMEA). VALSAT is used to classify value-added and non-value-added activities, while FMEA prioritizes waste based on Risk Priority Number (RPN). The results show that defects are the most dominant waste (RPN 294), followed by waiting and inventory. Process mapping reveals a total lead time of 370 minutes, in which 60 minutes are non-value added. Improvement recommendations include scheduling preventive maintenance, aligning raw material orders with actual demand, optimizing operator coordination, applying FIFO in inventory handling, and increasing transportation efficiency. This integrative approach provides a structured method for identifying critical waste sources and supports operational efficiency improvement in food-processing industries.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh kualitas layanan, kepercayaan, dan kepuasan nasabah terhadap loyalitas nasabah pada Bank Maybank KCP Jemur Andayani. Latar belakang penelitian ini didasari oleh meningkatnya persaingan dalam industri perbankan yang menuntut bank untuk mampu mempertahankan loyalitas nasabah sebagai strategi dalam membangun hubungan jangka panjang dan meningkatkan keunggulan kompetitif. Penelitian ini menggunakan metode kuantitatif dengan pendekatan asosiatif kausal. Data penelitian diperoleh melalui penyebaran kuesioner berbasis Google Form kepada 109 nasabah aktif Bank Maybank KCP Jemur Andayani. Teknik pengambilan data dilakukan secara langsung serta melalui distribusi WhatsApp blast. Instrumen penelitian diuji menggunakan uji validitas dan reliabilitas, sedangkan analisis data dilakukan dengan analisis regresi linier berganda menggunakan program SPSS versi 26. Hasil penelitian menunjukkan bahwa secara parsial kualitas layanan, kepercayaan, dan kepuasan nasabah berpengaruh positif dan signifikan terhadap loyalitas nasabah. Selain itu, secara simultan ketiga variabel tersebut juga berpengaruh positif dan signifikan terhadap loyalitas nasabah. Nilai koefisien determinasi sebesar 50,7% menunjukkan bahwa kualitas layanan, kepercayaan, dan kepuasan nasabah mampu menjelaskan lebih dari separuh variasi loyalitas nasabah. Kesimpulan penelitian ini menegaskan bahwa peningkatan kualitas layanan, penguatan kepercayaan, serta pemenuhan kepuasan nasabah memiliki peran penting dalam membangun dan mempertahankan loyalitas nasabah. Oleh karena itu, pihak bank disarankan untuk terus meningkatkan kualitas pelayanan, menjaga keamanan transaksi, serta memperkuat program loyalitas guna mempertahankan kepercayaan dan komitmen nasabah.

Abstract

Ameri Jasa Antares Andalan adalah perusahaan jasa keamanan yang tengah mengalami penurunan kinerja karyawan, ditandai dengan menurunnya kualitas, kuantitas, ketepatan waktu, dan kemampuan menyelesaikan tugas. Hal ini disebabkan oleh kurangnya ketelitian, keterlambatan, serta manajemen waktu dan keterampilan kerja yang tidak optimal. Penurunan kinerja diduga dipengaruhi oleh lingkungan kerja yang kurang mendukung (pencahayaan, suhu, hubungan antar karyawan), rendahnya disiplin (sering terlambat dan absen), serta stres kerja akibat tekanan dan tuntutan berlebih. Penelitian ini bertujuan menganalisis pengaruh lingkungan kerja, disiplin, dan stres terhadap kinerja karyawan. Seluruh populasi karyawan sebanyak 97 orang dijadikan sampel (sampel jenuh). Hasil penelitian menunjukkan bahwa ketiga variabel tersebut, baik secara parsial maupun simultan, berpengaruh signifikan terhadap kinerja karyawan di PT. Ameri Jasa Antares Andalan Medan.
