Abstract

Digital technology development has transformed the business landscape, particularly for Micro and Small Enterprises (MSEs), where Digital Accounting Information Systems (AIS) have become a critical tool. Digital AIS enhances operational efficiency, financial planning, and marketing, ultimately impacting revenue growth, with entrepreneur education being a crucial factor for successful adoption. This descriptive quantitative study aims to analyze the relationship and correlation direction between the implementation of digital AIS and the characteristics of SMEs in Indonesia. It utilizes panel data from the 2011-2023 SME profile surveys issued by Statistics Indonesia (BPS) and data on accounting software available on the Play Store. The indicators for SME characteristics are business capital, revenue, marketing, and education. The indicators for accounting software are rating, reviews, and downloads. The data were analyzed using Spearman's non-parametric statistical test. The results indicate a significant correlation between Digital AIS adoption and business capital and marketing, but no significant correlation with revenue and education. These findings underscore the necessity to develop and promote a holistic, context-based AIS implementation model. This model should be designed with user-friendly, integrated features and support certification programs for SMEs that demonstrate high-quality AIS implementation. Keywords: Business Capital, Marketing Revenue, Education, Digital Accounting Information System (AIS)

Abstract

This research was conducted to assess the quality of Scaffolding and visualization in the presentation of the Mathematics Module material for Grade X KD 3.2 regarding 3D vector material. The approach used in this research is a qualitative descriptive approach, which is carried out by analyzing the structure of the material, illustrations, example questions, and exercises provided in the module using content analysis techniques. The focus of the analysis conducted leads to several main aspects, including: (1) The sequence and form of Scaffolding presented as support in understanding the concept gradually, and (2) The effectiveness of visualization to help define and organize spatial vector data in space. This research resulted in a finding that the module has used Scaffolding with a tiered presentation of concepts, starting from the initial stage, namely the introduction of vector material in space to the stage of applying operations on vectors. However, on the other hand, it was also found that there are several stages of this Scaffolding that are not consistent, namely in the transition from examples to exercises which require a higher level of independence. Based on the visualization, the module utilizes spatial coordinate diagrams and vector arrow representations. However, some visuals lack detail in depicting orientation and depth in space, potentially leading to misconceptions among students. Overall, the module provides sufficient support for learning, but further strengthening of conceptual visualizations and more systematic Scaffolding is needed to optimally facilitate students' spatial thinking.

Abstract

Artikel ini menyajikan analisis kritis terhadap buku CLP-3 Multivariable Calculus karya Feldman, Rechnitzer, dan Yeager dengan fokus pada kekuatan pedagogis, potensi kesalahan konseptual, dan implikasinya bagi pembelajaran Kalkulus Multivariabel. Penelitian ini menggunakan pendekatan kualitatif melalui analisis dokumen, dengan menelaah secara sistematis struktur bab, alur penyajian materi, representasi konsep kunci (limit multivariabel, turunan parsial, gradien, optimasi, dan integral lipat), serta konsistensi notasi dan ketepatan rumus. Analisis dilengkapi dengan perbandingan terhadap beberapa buku dan sumber kalkulus multivariabel lain yang diakui secara luas.Hasil kajian menunjukkan bahwa CLP-3 Multivariable Calculus memiliki sejumlah kekuatan utama, antara lain struktur materi yang runtut, keterkaitan yang kuat dengan kalkulus satu variabel melalui strategi daur ulang konsep, penggunaan visualisasi geometris dan alat bantu prosedural (misalnya tree diagrams untuk Chain Rule), serta kelimpahan latihan yang disertai petunjuk dan solusi. Di sisi lain, ditemukan beberapa kelemahan, seperti status buku yang masih bersifat work in progress, ketergantungan pada seri CLP sebelumnya, penempatan konsep penting (misalnya Jacobian dalam koordinat umum) sebagai materi opsional, serta sejumlah ketidaktepatan notasi, rumus, dan penulisan yang berpotensi menimbulkan miskonsepsi. Implikasi dari temuan tersebut adalah bahwa CLP-3 Multivariable Calculus tetap layak digunakan sebagai buku ajar utama pada mata kuliah Kalkulus Multivariabel yang berorientasi pada pemahaman konseptual dan pembuktian, dengan syarat penggunaannya disertai klarifikasi konsep oleh dosen, pemanfaatan lembar errata, serta integrasi dengan bahan pendamping yang menyesuaikan konteks mahasiswa. Selain itu, analisis ini menegaskan pentingnya peninjauan kritis terhadap buku teks matematika sebelum dan selama digunakan dalam proses pembelajaran.

Abstract

The values ​​and spirit of unity and the prohibition of division have long existed and are taught by Islam, as in Surah Al Imran verse 103. Based on the interpretation of Ibn Kasir, Al Misbah, and Al Qurtubi, it explains the importance of unity so that there is a "terrible" threat if it is violated. (enmity/ divorce). This indicates the importance of unity in life. Our scholars and founding fathers have also reminded us of the importance of unity. Departing from the importance of the value and spirit of unity, in the context of handling the spread of Covid-19, especially in Indonesia, the values ​​and spirit of unity need to be instilled in every heart because the values ​​and spirit of unity have long been taught and there are many examples of success due to the value of unity. This study focuses more on the study of interpretations (Ibn Kasir, Al Misbah, and Al Qurtubi) regarding surah Al Imran verse 103 and is associated with arguments and text texts that are relevant to the values ​​of unity. Through the descriptive method, Surah Al Imran verse 103 emphasizes that the existing values ​​of unity can be implemented in dealing with the Covid-19 pandemic, including framing unity in faith, unifying in the level of obedience, and uniting in warding off hoax & self-control.

Abstract

Prolonged inheritance distribution is a recurring phenomenon in Muslim society that often gives rise to legal uncertainty, family conflict, and the neglect of the objectives of Islamic law. This study examines the issue of delayed inheritance distribution from the perspective of al-maslahah and legal certainty, highlighting the tension between normative Islamic inheritance rules and their practical application. The research employs a normative legal method combined with an empirical (socio-legal) approach. Normative analysis is conducted by examining statutory regulations, court decisions, and doctrines of fiqh and ushul fiqh related to inheritance law, with particular attention to the principles of al-maslahah and legal certainty. The empirical approach is employed to investigate the social realities that contribute to the delay in inheritance distribution, including family dynamics, cultural considerations, psychological factors, and institutional practices. This approach is essential because prolonged inheritance cases are not merely normative legal issues but are also influenced by non-legal factors embedded in social life. By integrating normative and empirical perspectives, this study provides a comprehensive understanding of the causes and implications of delayed inheritance distribution. The findings are expected to contribute to the development of a more responsive and just framework for inheritance law that upholds al-maslahah and ensures legal certainty in Islamic inheritance practices.
