Hajj is one of the pillars of Islam that must be carried out by all Muslims for those who can afford it. The implementation of the hajj of course has pillars and conditions that regulate the implementation of the hajj, if they commit an offense that is not in accordance with the pillars of hajj, then a Muslim or Muslim woman can be sanctioned.  In the implementation of the Hajj, the sanctions given are called dam. The research was conducted to find out the views of the top four Islamic imams on the payment of fines (dam) in the implementation of the Hajj, the types of violations that can be imposed and to see the development of the implementation of Hajj for Indonesian pilgrims. The research was carried out using qualitative methods. The subject of the study is an Indonesian hajj pilgrim guide who has done it. The four major sects (Hanafi, Maliki, Shafi'i, Hambali) agree that dam is a fine of worship that must be paid when pilgrims violate the prohibition or abandon the obligation of Hajj, with the main form of slaughtering animals, feeding the poor, or fasting if they are unable to afford it. The difference lies in the limit of a violation so that it is obligatory and a choice between slaughter, food alms, and fasting in each sect.  

Financial literacy plays an important role in supporting the ability of Micro, Small, and Medium Enterprises to adapt to the development of digital payments in Indonesia. The increasing use of QRIS, e-wallets, mobile banking, and technology-based payment services requires MSME actors to understand the benefits, risks, and proper use of digital financial services. This study aims to examine the role of financial literacy in the use of digital payments among MSMEs in Indonesia, including supporting factors, obstacles, and implications for strengthening MSME digitalization. This research uses a descriptive qualitative approach with a systematic literature study method. The data were obtained from 13 scientific articles indexed in nationally accredited journals at least Sinta 4, published between 2021 and 2026, and supported by official documents from relevant authorities. The findings show that financial literacy plays a role in increasing the readiness, trust, and decisions of MSME actors to use digital payments. However, low financial literacy, perceived risk, limited infrastructure, and conventional transaction habits remain obstacles to digital payment adoption. The implications of this study indicate the need for inclusive digital financial education, continuous assistance, and collaboration among the government, regulators, financial institutions, and fintech providers in strengthening the digital transformation of MSMEs.

This research examines the application of the Elliptic Curve Digital Signature Algorithm (ECDSA) in a blockchain system as a security solution for digital payment systems in Indonesia. Using a descriptive-qualitative approach based on literature review and conceptual simulations using Python, this study discusses the working principles of ECDSA, its advantages over other digital signature algorithms, and the challenges of its adoption in Indonesia. The results show that ECDSA provides high cryptographic efficiency, maintains transaction authenticity and integrity, and supports a transparent decentralized system. The academic simulations include not only KYC processes, top-ups, transactions, validation by validators, and block recording, but also demonstrates the formation of an interconnected multi-level blockchain and tests scenarios for rejecting manipulated or invalid transactions. The contribution of this research lies not only in the theoretical review but also in the implementation illustrations that can be used as a basis for education and the initial development of blockchain-based digital payment systems. The research results show that ECDSA is capable of providing a high level of efficiency in the encryption and transaction verification process, maintaining data integrity and authenticity, and supporting a decentralized and transparent system. The academic simulations included the KYC process, wallet creation using ECDSA keys, balance top-ups through bank integration, transaction creation and validation, and block recording in the blockchain. Specifically, the simulations successfully demonstrated how new blocks are added to the chain by referencing the previous block's hash, as well as how transactions with corrupted signatures, manipulated amounts, or insufficient balances are automatically rejected by the validator consensus mechanism, maintaining system integrity. This research contributes not only theoretically, but also through conceptual representations that can be used as an educational foundation and for the initial development of blockchain-based digital payment systems in Indonesia.

This study aims to classify customer payment methods at 17 Coffee & Eatery using machine learning algorithms, namely Naïve Bayes and Support Vector Machine (SVM). The increasing use of digital and non-cash payments has generated large volumes of transaction data that are rarely analyzed optimally, even though such data contain valuable information for business decision making. This research used secondary transaction data collected from January to March 2025, consisting of 10,147 transaction records. The dataset included several attributes such as order time, payment time, transaction type, total sales, number of items, and payment method. Data preprocessing was performed through data cleaning, feature engineering, normalization, and label encoding before being divided into training and testing sets with an 80:20 ratio. The Naïve Bayes and SVM models were then trained and evaluated using accuracy, precision, recall, F1-score, and ROC–AUC metrics. The results show that both algorithms were able to classify payment methods effectively, but SVM achieved higher accuracy and more stable performance than Naïve Bayes. These findings indicate that SVM is more suitable for handling complex and heterogeneous transaction patterns. The implementation of machine learning for transaction classification can support more efficient financial management and data-driven decision making for small and medium enterprises in the culinary sector.

This study aims to compare the effectiveness of QRIS with other cashless payment methods in driving the development of the digital economy in Indonesia. The background to this study stems from the increasing use of digital transactions and the strategic role of QRIS as a national standard for QR-based payments. Google Forms was used to disseminate the survey online and successfully collected 100 respondents who were users of cashless digital payment services. A purposive sampling technique was used to ensure that respondents had experience using QRIS and other digital payment methods. Data were examined using the SmartPLS 4 program using a Partial Least Squares Structural Equation Modeling (PLS-SEM) approach to test the relationships between variables. The results indicate that perceived ease of use, transaction security, and influence on digital behavior have a positive or significant influence on QRIS effectiveness. However, availability and accessibility variables did not have a significant effect. This finding indicates that QRIS effectiveness is more influenced by user experience and perceptions, rather than availability or ease of access. This research is expected to contribute to the development of strategies to increase digital payment adoption in Indonesia.

The digital transformation of payment systems has become essential for micro, small, and medium enterprises (MSMEs) to improve transaction efficiency and expand market accessibility. This community service program was conducted to introduce and implement the use of QRIS through the Dana Bisnis application for four MSMEs located in the Makam Raja-Raja Imogiri tourism area Yogyakarta : Warung Wahyu, Warmindo Babe, Warung Pecel Bu Yani, and Warung Pecel Bu Elti. Initially, all MSMEs relied solely on cash transactions, leading to difficulties in financial recording and limited access to digital financial services. The program consisted of several stages, including on-site surveys, problem identification, explanation of digital payment benefits, training on QRIS registration and usage, and continuous assistance during the transition process. The results indicate a significant improvement in MSMEs’ understanding of digital payment systems and a gradual shift towards non-cash transactions. Evaluation findings show that approximately 60% of daily transactions were conducted via QRIS, and business owners reported benefits such as simplified bookkeeping, faster payment processing, and enhanced transaction security. This program demonstrates that QRIS-based digital payment systems can be effectively implemented in traditional MSMEs through proper mentoring and hands-on guidance. The initiative also plays a strategic role in promoting financial inclusion and strengthening MSME competitiveness in tourism areas. Continued efforts remain necessary, particularly in enhancing digital literacy and expanding access to supporting technology to ensure equitable adoption of digital payment systems.

The rapid growth of financial technology has led to the emergence of digital wallets as an efficient and practical means of payment. One of the most widely used services in Indonesia is Shopeepay, particularly among Generation z, who are known for their adaptability to new technologies. This study aims to examine to influence of perceived usefulness (X1) and perceived risk (X2) on the intention to use digital wallets (Y), with Shopeepay payment method (M) as a moderating variable. This research employed a quantitative approach by distributing questionnaires to 60 University students who actively use Shopeepay. The collected data were analyzed using multiple linier regression and Moderated Regression Analysis (MRA). The findings reveal that perceived usefulness has a positive and significant effect on the intention to use Shopeepay (sig. 0,004<0,05). Perceived risk also shows a significant effect in thr multiple regression test (sig. 0,003<0,05), but becomes insignificant when tested with MRA (sig. 0,094>0,05). This suggests that impact of risk tends to weaken when moderated by the payment methode. Furthermore, the Shopeepay payment method itself does not significantly influence user intention (sig. 0,067>0,05) collectively, perceived usefulness and perceived risk significantly affect the intention to use Shopeepay (sig. 0,001).
