Recieved: July 2025 Accepeted: September 2025 Published: September 2025 ABSTRAK Perkembangan teknologi finansial telah menghadirkan layanan pembayaran digital seperti Shopee PayLater, yang semakin populer di kalangan masyarakat, termasuk mahasiswa Ekonomi Syariah di STAI Al-Ittihad Cianjur. Namun, penggunaan layanan ini menimbulkan dilema karena adanya unsur riba yang bertentangan dengan prinsip ekonomi Islam. Penelitian ini bertujuan untuk menganalisis pengaruh pengetahuan tentang riba terhadap keputusan mahasiswa menggunakan Shopee PayLater serta mengkajinya dalam perspektif ekonomi Islam. Penelitian menggunakan pendekatan kuantitatif dengan metode survei. Data dikumpulkan melalui kuesioner yang disebar kepada 90 mahasiswa STAI Al-Ittihad Cianjur dan dianalisis menggunakan regresi linier sederhana melalui SPSS. Hasil penelitian menunjukkan pengetahuan tentang riba berpengaruh negatif dan signifikan terhadap keputusan penggunaan Shopee PayLater dengan persamaan regresi Y = 23. 165 Ae 0. Namun, pengaruh tersebut tidak signifikan secara statistik, dengan nilai t hitung -1. 156 < t tabel 1. 664 dan 250 > 0. Nilai RA sebesar 0,058 menunjukkan bahwa hanya 5,8% keputusan penggunaan dipengaruhi oleh pengetahuan tentang riba, sedangkan 94,2% dipengaruhi oleh faktor lain. Artinya, semakin tinggi pemahaman mahasiswa terhadap riba, semakin rendah mereka untuk menggunakan layanan tersebut. Penelitian ini menyimpulkan bahwa Shopee PayLater tidak sesuai dengan prinsip ekonomi Islam karena mengandung unsur riba. Implikasinya, edukasi terkait literasi keuangan syariah perlu ditingkatkan agar masyarakat lebih selektif dalam memilih layanan keuangan digital. Kata Kunci: Pengetahuan Riba. Keputusan Penggunaan.

ABSTRACT The advancement of financial technology has introduced services such as Shopee PayLater, which have become increasingly popular among the public, including Sharia Economics students at STAI Al-Ittihad Cianjur. However, using this service creates a dilemma because it involves riba, which contradicts Islamic economic principles. This study aims to analyze the effect of knowledge about riba on studentsAo decisions to use Shopee PayLater and to examine it from the perspective of Islamic economics. This research used a quantitative, survey-based approach. Data were collected using questionnaires distributed to 90 students at STAI Al-Ittihad Cianjur and analyzed using simple linear regression in SPSS. The results of the study show that knowledge about riba has a negative and significant effect on the Copyright A 2025.

The R2 value of 0. 058 indicates that 8% of the decision to use Shopee PayLater is affected by knowledge of riba, while other factors account for the remaining 94. This means that the higher the studentsAo understanding of riba, the lower their tendency to use the service. This study concludes that Shopee PayLater is not in accordance with the principles of Islamic economics because it contains elements of riba. The implication is that education related to Islamic financial literacy needs to be enhanced so that the public becomes more selective in choosing digital financial services.

INTRODUCTION The rapid advancement of financial technology has given rise to a range of digital payment services, including Shopee PayLater. This service has become highly popular among Indonesians, ranking at the top in terms of brand awareness and usage. According to Databoks data. West Java Province, which has a majority-Muslim population, recorded the highest PayLater usage in 2024. Figure 1. PayLater Users Data in West Java in 2024 Source: https://databoks. This popularity raises a problem because, from an Islamic perspective, the PayLater system is considered to contain elements of riba . , which is prohibited. Although there is a fatwa from the National Sharia Council of the Indonesian Ulema Council (DSNMUI) No. 117/DSN-MUI/II/2018 stating that information technology-based financing services are permissible as long as they do not contradict sharia principles and use valid Copyright A 2025.

Sarah Robiatul Adawiyah2. Intan Sri Lestari3 Ar-Rihah: Jurnal Keuangan dan Perbankan Syariah Vol. 05 No. 02 September 2025 contracts (Fitriyah, 2. The fatwa emphasizes that Shopee PayLater contradicts Sharia principles due to the presence of interest. However, this service remains widely used. The research gap is identified from several previous studies that show varying Some studies find that knowledge about riba does not have a significant effect on interest or loyalty in using PayLater services. However, other studies find that knowledge about riba has a positive, significant effect on interest in using similar services. This variation in findings indicates the need for further research into the factors that affect the decision to use PayLater services among groups with a strong background in religious Thus, a preliminary observation was conducted among Islamic Economics students at the Islamic College (STAI) Al-Ittihad Cianjur to measure how many students use the Shopee PayLater service, and the following data were obtained. Figure 2. Shopee PayLater Users at STAI Al-Ittihad Source: Preliminary Research Data, 2024 In addition, preliminary data were obtained regarding how many Islamic Economics students at the STAI Al-Ittihad Cianjur (Islamic Colleg. are aware that Shopee PayLater contains elements of riba according to the Fatwa of the National Sharia Council of the Indonesian Ulema Council (DSN-MUI) No. 117/DSN-MUI/II/2018 concerning information technology-based financing services based on sharia principles (Hadrianto et al. , 2. , as Copyright A 2025.

Knowledge of Riba Among Islamic Economics Students at STAI Al-Ittihad Source: Preliminary Research Data, 2024 Based on the presented data and background, this study specifically analyzes the urgency of knowledge about riba in relation to the decision to use Shopee PayLater among Islamic Economics students at the Islamic College (STAI) Al-Ittihad Cianjur, who are expected to have a deep understanding of riba. This raises a research question: whether the studentsAo decision to use Shopee PayLater is affected by their knowledge of riba, and how Islamic economics views the Shopee PayLater service. The results of this study are expected to provide contributions and scientific benefits that address the existing research gap, namely, to determine whether knowledge of riba affects the decision to use Shopee PayLater or not, and to understand how Islamic economics views this service. Furthermore, the study aims to provide education and foster critical awareness, especially among Islamic Economics students, regarding the implications of using digital financial services from an Islamic economics perspective. Literature Review The literature review in this study was conducted by reviewing previous scientific works with similar titles or variables. Several studies served as primary references. One of them is a study conducted by Salma Salsabila (Salsabila, 2. titled AuThe Effect of Religiosity. Knowledge About Riba, and Social Factors on the Loyalty of Yogyakarta Community in Using the Akulaku PayLater Application with Debt as a Moderating Variable. Ay This research shares similarities in variables but differs in the subject of study. Therefore, this study is expected to expand on or complement previous research. Based on a review of earlier studies, several relevant theories are identified as follows. Knowledge According to the Indonesian Dictionary (Kamus Besar Bahasa Indonesia. KBBI), knowledge is everything that a person knows or possesses regarding a particular subject. Knowledge can also be defined as a new understanding that consists of a combination of skills, interpretation, context, and systematic reflection (Utami, 2. Meanwhile.

Intan Sri Lestari3 Ar-Rihah: Jurnal Keuangan dan Perbankan Syariah Vol. 05 No. 02 September 2025 There are three indicators used to measure knowledge according to Spencer . s cited in Rais, 2. Analytical Thinking (AT), the ability to think analytically to identify and understand problems by breaking them down into basic components and systematically examining cause-and-effect relationships. Conceptual Thinking (CT), the ability to understand a condition or problem through a conceptual approach by combining various ideas and pieces of information to form a comprehensive understanding. Expertise (EXP), knowledge directly related to job performance, encompassing professional, technical, and managerial abilities, as well as the motivation to utilize, develop, and share them with others. Knowledge of Riba Knowledge of riba is the understanding of Islamic teachings that have become oneAos belief regarding economic transactions involving the addition of value or interest. This knowledge serves as a tool to guide society in preventing practices that contain elements of Etymologically, riba means ziyadah . , which linguistically implies growth and increase, while in technical terms, riba refers to the unlawful acquisition of an excess amount from the principal or capital (Ipandang, 2. The indicators used to measure knowledge of riba are proposed by Aji et al. Additional Money, the presence of any form of addition required in debt or sale transactions, which is categorized as riba. Profit, the profit obtained in a transaction that is not objective and benefits only one party, thereby violating the validity condition of the contract . utual consent of both partie. Additional Cost, the increase in value applied to any form of muamalah activity involving debt or sale transactions, which contradicts and is not permitted in Islamic economics because it violates the principle of justice.

This service is supervised by the Financial Services Authority (OJK). However, from the perspective of Islamic economics, this service is considered to contradict sharia principles due to the presence of riba elements, such as a minimum interest rate of 2. 95% and a late payment penalty of 5% of the total bill, which are categorized as riba nasiAoah . xcess charged due to a delay in payment or extension of tim. and riba qardh . n additional amount required from a loan transactio. (Fitriani & Baidhowi, 2. The feature indicators of Shopee PayLater, according to Rahima and Cahyadi . are as follows: Satisfaction, the level of satisfaction obtained by users from the services, features, credit limit, and other conveniences offered.

A responsive and fast service that provides convenience to users so that they do not have to wait long when urgent needs arise. RESEARCH METHOD The approach used in this study was quantitative, as explained by Sugiyono . s cited in Satria & Imam, 2. , that the quantitative approach is based on the philosophy of positivism and is used to examine a particular population or sample. The quantitative method used in this study was a survey. The population consisted of all Islamic Economics students at STAI Al-Ittihad Cianjur, totaling 116 individuals across first to seventh semesters, including both regular and non-regular classes. By using the Isaac and Michael formula, the researcher determined a sample size of 90 respondents. The sampling technique used was Copyright A 2025.

Normality Test Results Based on the data in Figure 7, the p-value of 0. 200 > 0. 05 indicates that the data on knowledge about riba and the decision to use Shopee PayLater are normally Heteroscedasticity Test According to Maramis et al. , the heteroscedasticity test aims to determine whether there is a deviation of classical assumptions in the form of unequal variance in the regression data. This study uses the Glejser method to test for The following are the results of the heteroscedasticity test. Figure 8. Heteroscedasticity Test Results Based on Figure 8, the heteroscedasticity test for the research data on the effect of knowledge about Riba on the decision to use Shopee PayLater shows a p-value of 091, which is greater than 0. Therefore, the research data are normally distributed and do not show heteroscedasticity. Simple Linear Regression Test Simple linear regression analysis is a statistical test used in research that involves one variable. X, aiming to examine whether there is a relationship between one independent variable and one dependent variable (Alwy Yusuf et al. , 2. This means that a simple linear regression analysis is intended to determine whether Copyright A 2025. Ar-Rihlah: Jurnal Keuangan dan Perbankan Syariah Fakultas Ekonomi dan Bisnis Islam Universitas Suryakancana The Effect Knowledge About Riba on The Decision to Use Shopee Paylater in The Perspective Of Islamic Economic Yulia Eka Rini1*. Sarah Robiatul Adawiyah2. Intan Sri Lestari3 Ar-Rihah: Jurnal Keuangan dan Perbankan Syariah Vol. 05 No. 02 September 2025 knowledge about riba (X) affects the decision to use Shopee PayLater (Y). The equation for simple linear regression is Y = a bX. In this regression test, a problem was found that required the regression analysis to be repeated or conducted twice. This was because the results of the first regression test produced an equation inconsistent with previous studies and Islamic economic theory, which holds that a Muslim who knows about riba tends not to use the Shopee PayLater service, as Shopee PayLater is identified as containing elements of riba. The following are the results of the first regression test. Figure 9. First Regression Test Results Based on Figure 9, the regression equation obtained is Y = -1. This means that an increase in knowledge about riba (X) by 1 unit will affect the use of Shopee PayLater (Y) by 0. 761, holding -1. 741 constant. Based on the explanation above, if a person has knowledge about riba = 0 . or example, has no knowledge at all about rib. , then the decision to use Shopee PayLater is predicted to be -1. Each increase of one unit in knowledge about riba (X) will result in an average increase of 0. 761 units in the decision to use Shopee PayLater (Y). Based on the presentation and interpretation of the simple linear regression test results, it can be concluded that there is an inconsistency or irrelevance between the test results and the existing theory. Then, the researcher conducted further analysis and repeated the testing process by removing the third indicator statement of the Shopee PayLater usage variable in the fifth item of the questionnaire, which states: AuThe concept of fines and interest imposed by Shopee PayLater for late payment can still be fulfilled and does not harm users. Ay. The reason for removing the statement in the third indicator is based on the results of analyzing and examining the research data obtained, using previous studies as references. The statement was found to be irrelevant to the research and the characteristics of the respondents. Consequently, it produced data that were inconsistent with the theory and previous studies. The following are the results of the Copyright A 2025.

Sarah Robiatul Adawiyah2. Intan Sri Lestari3 Ar-Rihah: Jurnal Keuangan dan Perbankan Syariah Vol. 05 No. 02 September 2025 repeated simple linear regression test obtained from the reanalysis. Figure 10. Second Regression Test Results After conducting the retest, the results obtained show the following simple linear regression equation: Y = 23. 165 - 0. This means that based on the equation Y = 23. 165 - 0. 143X, an increase in knowledge about riba (X) by one unit will affect the use of Shopee PayLater (Y) by -0. 143 units at a constant value of If a person has knowledge about riba = 0 units . or example, has no knowledge at all about rib. , then the decision to use Shopee PayLater is 23. 165 units. This means that without knowledge about riba. Islamic Economics students tend to use Shopee PayLater, with a constant value of 23. Furthermore, each additional unit of knowledge about riba (X) will result in a decrease of 0. 143 units in Shopee PayLater usage. These results align with Islamic economic theory, which considers Shopee PayLater a transaction that does not comply with Islamic law, based on Fatwa No. 117/DSN-MUI/II/2018. Therefore, each increase in studentsAo knowledge about riba will reduce the decision to use Shopee PayLater by -0. The results of this repeated simple linear regression test are reinforced by an interview with one of the respondents. Based on the interview findings, the respondent explained that the use of Shopee PayLater is affected by urgent needs for which there are no other alternatives besides using the Shopee PayLater service. Then, after learning about the law of riba, the respondent became more cautious in using online payment services and prioritized other alternatives when faced with urgent needs. This explanation shows that students use the Shopee PayLater service only to meet urgent needs and seek other alternatives before choosing Shopee PayLater as their final option. Partial Test . -tes.

Based on the data presented, it can be concluded that knowledge of riba among Islamic Economics students at STAI Al-Ittihad Cianjur does not have a significant effect on the decision to use Shopee PayLater. This decision is affected by factors beyond knowledge of riba. Uji Koefisien Determinasi (R. According to Imam Ghozali . alam Bode et al. , 2. , the coefficient of determination (R. is used to indicate the extent to which variations in the dependent variable can be explained by the independent variable within a regression model. The RA value ranges from 0 to 1. A value indicates that the independent variable contributes only minimally to explaining the variation in the dependent variable. Conversely, an R2 value close to 1 indicates that the independent variable has strong Copyright A 2025.

Coefficient of Determination Test Results From Figure 12, the R-square value is 0. 058, which, when converted to a percentage, equals 0. 058 y 100% = 5. The decision to use Shopee PayLater is affected by the variable knowledge about riba by 5. 8%, while the remaining 94. is affected by other variables outside knowledge about riba, such as promotion, process convenience, lifestyle, income, or the lack of sharia-based alternatives. DISCUSSION Knowledge About Riba Toward the Decision to Use Shopee PayLater Based on the processed data from the respondents of this study, namely Islamic Economics students at STAI Al-Ittihad Cianjur, with a population of 116 students and a research sample consisting of 90 students. The research data were collected via questionnaires distributed via Google Forms. The results from the statistical tests conducted in SPSS 26 indicate that knowledge of riba has a negative, but non-significant, effect on the decision to use Shopee PayLater. Based on the hypothesis test results, knowledge about riba (X) has a calculated t-value of -1. 156 < critical t-value of 1. 664, with a significance value of 250 > 0. It can be concluded that the variable Knowledge about riba (X) has no significant effect on the variable Decision to Use Shopee PayLater (Y) partially, as indicated by the calculated t-value (-1. < critical t-value . and a significance value of 0. 250 > 0. Furthermore, the results of the simple linear regression test show that the effect of the variable Knowledge about riba (X) on the variable Decision to Use Shopee PayLater (Y) follows the equation Y = 23. 165 Ae From this equation, it can be seen that the variable Knowledge about riba (X) negatively affects the variable Decision to Use Shopee PayLater (Y).

In comparison, the remaining 94. 2% is affected by other factors. Islamic Economic Perspective on the Use of Shopee PayLater In line with technological advancements, digital payment technologies have also advanced, including widely known and used payment services such as Shopee PayLater. The PayLater payment system provides a service that helps users with the Aubuy now, pay laterAy payment scheme. This phenomenon tends to increase peopleAos preference for consumptive financing. From the perspective of Islamic economics, transactional convenience must still comply with sharia principles to avoid prohibited transactions and all forms of activities containing elements of riba and gharar (Pratiwi et al. , 2. Islamic economics allows the existence of debt or lending . However, additional charges are not permitted because, in Islamic economics, qardh is an economic activity aimed at mutual assistance rather than profit-making. This is in accordance with AllahAos command revealed to the Prophet in Surah Al-Baqarah: 280 and the hadith narrated by Ibn MasAoud. According to Wahab . , any addition to a transaction is categorized as riba nasiAoah, which is prohibited in Islamic economics. This is because an increase in debt value causes injustice to one of the parties to the transaction. In the modern economy, the Indonesian Ulema Council (MUI) and the National Sharia Council (DSN) have issued prohibitions on payment systems found to contain elements of riba, including Shopee PayLater, which was identified as containing such elements. The maslahah and social impact of the communityAos consumption behavior through the PayLater system will lead to excessive indebtedness, resulting in financial burdens and a decline in economic welfare. This condition contradicts the objectives of Islamic economics, which aim to promote the maslahah of the ummah and achieve equitable economic prosperity. Based on the review and theoretical explanation, it can be concluded that the Shopee PayLater payment system is not in accordance with Islamic economics and contradicts it, as it contains elements of riba and gharar . for users who do not fully understand the payment scheme. Therefore, it is necessary to enhance Copyright A 2025.

Intan Sri Lestari3 Ar-Rihah: Jurnal Keuangan dan Perbankan Syariah Vol. 05 No. 02 September 2025 knowledge about riba and Islamic financial literacy in accordance with the principles of Islamic economics so that consumers can make transaction decisions that comply with Islamic law. Referring to the research conducted among Islamic Economics students at the Islamic College (STAI) Al-Ittihad Cianjur, studentsAo knowledge about riba affects their decision to use Shopee PayLater. However, the effect is not statistically Based on theory, the results of this study are consistent with existing theoretical concepts: students who have knowledge of riba tend not to use the Shopee PayLater payment system, as It involves riba . and is categorized as a transaction not permissible in Islamic economics. CONCLUSION The research conducted directly with Islamic Economics students at STAI Al-Ittihad Cianjur yielded quantitative data for the study titled The Effect of Knowledge about Riba on the Decision to Use Shopee PayLater in the Perspective of Islamic Economics, resulting in two main conclusions. The first conclusion, based on the partial test results, is that knowledge about riba (X) has a negative but non-significant effect on the decision to use Shopee PayLater (Y). Therefore, students who have knowledge about riba are less likely to choose Shopee PayLater. However, based on the coefficient of determination test, the effect of knowledge about riba (X) on the decision to use Shopee PayLater (Y) has an R-square of 058 . 8%), indicating that other variables affect the remaining 94. The results of this study align with previous research conducted by Salsabila . Second, the Shopee PayLater payment system is not in accordance with Islamic economics and contradicts it, as it contains elements of riba and gharar . for users who do not fully understand the payment scheme. Therefore, it is necessary to enhance knowledge about riba and Islamic financial literacy in accordance with the principles of Islamic economics so that consumers can make transaction decisions that align with Islamic law. The results of this study among students are consistent with Islamic economic theory, although they do not show a significant effect. REFERENCES
