Abstract

Blockchain technology is disrupting traditional practices in accounting and audit fields. This article explores how blockchain's transparency, immutability, and decentralization are reshaping financial transactions and record-keeping. Conventional accounting faces challenges like data accuracy and fraud prevention, which blockchain addresses through an unalterable, decentralized ledger for real-time financial transaction records. Each transaction is securely linked using cryptography, forming a tamper-proof chain that reduces fraud risk and ensures an auditable trail. Blockchain's impact on accounting lies in its ability to automate processes through smart contracts. These self-executing codes enable instant revenue recognition, automated intercompany transactions, and compliance with standards. Blockchain also enhances audit efficiency by granting auditors access to immutable financial data and automating audit procedures. Despite challenges like scalability and privacy, blockchain's transformative potential is evident in real-world applications across sectors. Its implementation demands stakeholder collaboration to navigate technical and ethical considerations. As blockchain evolves, its role in accounting and audit is set to redefine financial transparency and accountability.

Abstract

Students feel the impact of the spread of Covid-19, such as changes in the provision of services in educational institutions, such as formal education at all levels, non-formal education, to academics. The government began to implement an online learning system (online). The problem during this online learning period is that many people are still not ready to face technology, both teachers and students. It happened in the early days of the pandemic. It results in challenges for the standard learning process, including challenges for teaching and giving assessments. It is because the teaching staff (teachers) always have daily assessment data that is usually carried out daily during everyday learning. However, during this PJJ period, teachers became confused about giving daily assessments to their students. The research aims to analyze and evaluate the online learning system using a platform that is easy to operate by teachers and can be accessed anywhere, namely Google Forms. In the Google Form application, there is an automatic calculation system in the form of student feedback where teachers do not bother to manually calculate the results of student learning evaluations. The analysis method used is the Technology Acceptance Model (TAM), which can determine users' attitudes towards the technology used, so that teachers can easily find out whether the tasks given to students are done by the students themselves, not with the help of parents.

However, despite its great potential, the MSME sector still faces various obstacles in developing its business, especially in increasing economic growth. One of these obstacles is the limited resources owned by MSMEs, both in terms of capital, labor, market access, technology, and so on. Padangsidimpuan City as one of the cities in North Sumatra Province has great potential in the development of MSMEs. One of the analytical methods that can be used to analyze the factors that influence the economic growth of MSMEs is the dynamic regression analysis model using the Ordinary Least Square (OLS) method. The urgency of the research is the increasing role of MSMEs as contributors to the economic growth of Indonesia and Padangsidimpuan City in particular. MSMEs are considered a strategic sector in economic development, especially in creating jobs and increasing the competitiveness of the national economy. However, MSMEs still experience obstacles in developing their businesses, especially in increasing economic growth. The purpose of this study is to analyze the factors that influence the economic growth of MSMEs in Padangsidimpuan City using the dynamic regression analysis model and the Ordinary Least Square (OLS) method. In addition, this study also aims to provide recommendations to the government and business actors in increasing the economic growth of MSMEs in Padangsidimpuan City.

Abstract

Perkembangan UMKM pada masa kini sangat berdampak terhadap tumbuhnya pasar ekonomi produktif yang menjadi fokus pemerintah untuk berkomitmen dalam pengembangannya. Hal ini terjadi dikarenakan ekonomi produktif sangat membantu dalam pengembangan perekonomian negara. Akan tetapi banyak pelaku UMKM yang mengelola usahanya tidak memiliki pengetahuan dasar dalam pengelolaan manajemen usaha, manajemen keuangan yang baik hingga keterampilan yang memadai untuk memajukan usahanya. UMKM “Sopou Batik Sibolatangan” kabupaten simalungun provinsi Sumatera Utara adalah UMKM yang saat ini sudah memulai industri ekonomi kreatif dengan membuat kain batik menggunakan motif khas kabupaten simalungun yang sering disebut “pinar” atau ornamen suku simalungun. Persaingan industri kain batik saat ini masih didominasi oleh pasar batik dari Pulau Jawa yaitu batik pekalongan, jogja dan daerah jawa lainnya yang masih banyak lagi memiliki motif khas jawa. Akan tetapi, kain batik dengan motif khas simalungun masih belum memiliki persaingan yang signifikan di pulau sumatera khususnya Sumatera Utara. Terlebih saat ini Danau Toba menjadi salah satu destinasi pariwisata prioritas dari 5 (lima) daerah wisata yang ditetapkan oleh Presiden Joko Widodo. Berdasarkan observasi yang dilakukan oleh Ibu Risnawati Damanik sebagai pemilik usaha “Sopou Batik Sibolatangan” ini, tercetuslah ide untuk membuat kain batik dengan motif / pinar khas kabupaten simalungun. Produk Sopou Batik ini sangat potensial untuk menjadi oleh oleh khas dari Simalungun. Berdasarkan hasil diskusi awal, ditemukan permasalahan mitra dalam melakukan pengembangan usaha antara lain tata kelola manajemen masih manual dan tradisional, terutama dalam bidang manajemen keuangan. Sopou Batik Sibolatangan belum mampu memisahkan antara uang untuk operasional rumah tangga dan usaha. Masalah lainnya adalah dari sisi kuantitas yaitu belum mampu dalam hal meningkatkan produksi secara cepat dan banyak karena keterbatasan peralatan produksi dan bahan baku. Sistem pemasaran yang dilakukan dengan cara mulut ke mulut (mouth to mouth marketing) tidak memberikan hasil yang optimal sehingga keuntungan yang didapatkan pun belum memenuhi harapan mitra. Mitra hanya melakukan penjualan terhadap orang sekitar rumah mitra yang dijadikan sebagai toko dan mengharapkan pembeli yang datang langsung karena memperoleh informasi dari orang yang pernah berkunjung ke toko mitra. Mitra UMKM “Sopou Batik Sibolatangan” belum menjadikan media sosial atau jaringan internet sebagai alat pemasaran. Masalah lainnya adalah tampilan kemasan (packaging) yang masih menggunakan plastik biasa sehingga tampilan produk menjadi kurang menarik. Berdasarkan uraian permasalahan di atas, maka solusi yang ditawarkan pada program ini adalah pengembangan usaha kerajinan dengan meningkatkan produktivitas melalui penambahan alat cetak pinar/motif batik simalungun dan peningkatan kemampuan sumberdaya manusia, tata kelola manajemen keuangan yang baik dan benar dengan membuatkan aplikasi manajemen keuangan yang memudahkan UMKM dalam mengelola keuangan. Adanya kegiatan pelatihan yang diberikan kepada mitra untuk peningkatan kemampuan mitra guna peningkatan jumlah produksi, adanya program digitalisasi dalam hal pemasaran melalui internet yaitu website dan media sosial, dan adanya kemasan yang baik dan menarik seperti logo dan label usaha, plastik kemasan (packaging) serta goodie bag yang identik dengan usaha UMKM “Sopou Batik Sibolatangan” Khas Simalungun.

In today's digital era, digital financial literacy plays a crucial role in shaping the behavior and investment decisions of the community. Padangsidimpuan City, one of the cities in Indonesia, faces challenges in adopting and implementing digital financial literacy among its citizens. Effective and efficient investment decision-making has become vital in the current economic context, where financial information is widely available but often complex and difficult for the general public to interpret.

Abstract

In today's digital era, the Rapid Application Development (RAD) method has shown great potential across various sectors, including education and career development. However, its application in electronic career systems, or E-Careers, remains relatively uncommon. This creates an urgency to conduct research on how the Rapid Application Development (RAD) method can be applied in E-Career systems to enhance efficiency, transparency, and security in the career search process for students. This study aims to apply the Rapid Application Development (RAD) method in the development of a mobile-based E-Career system at Politeknik LP3I Cirebon Campus. One sector that can benefit from the Rapid Application Development (RAD) method is the electronic career system or E-Career. This system aims to facilitate career searches for students in a more efficient and transparent manner. However, a challenge in implementing this system is ensuring that the data shared between different parties is secure and unalterable. The primary goal is to create a system that is not only efficient but also secure and transparent. Thus, students can search for careers more efficiently and transparently, while companies can more easily find the right candidates. Additionally, this research also aims to identify and address challenges in integrating the Rapid Application Development (RAD) method with mobile applications.
