The convenience, speed, and promotional programs offered through digital payment services have the potential to influence consumer spending behavior, particularly among younger generations. This study aims to analyze the effect of digital payments on consumptive behavior based on findings from previous studies. The research employed a qualitative literature review approach by collecting and analyzing relevant scientific literature, including journals, articles, books, and research reports published between 2021 and 2025. Data were analyzed using content analysis to identify concepts, empirical findings, and patterns of relationships between digital payments and consumptive behavior. The results indicate that digital payments positively contribute to consumptive behavior through transaction convenience, reduced psychological barriers to spending, and various promotional incentives such as cashback and discounts. Furthermore, the use of digital payments is associated with an increase in impulsive buying behavior. However, financial literacy and self-control have been found to mitigate the tendency toward excessive consumption resulting from digital payment usage. Therefore, improving financial literacy and awareness in managing personal finances is essential to promote more responsible and sustainable use of digital payment technologies.</em></p>2026-07-18T00:00:00+00:00Copyright (c) 2026 Prosiding Seminar Nasional Ilmu Sosial dan Teknologi (SNISTEK)https://ejournal.upbatam.ac.id/index.php/prosiding/article/view/11718LITERATUR REVIEW: HUBUNGAN KINERJA LINGKUNGAN DAN PROFITABILITAS TERHADAP PENGUNGKAPAN LINGKUNGAN PERUSAHAAN DI INDONESIA 2026-06-22T01:55:22+00:00Dwita Diajeng Syawaliahdwitadiajeng48@gmail.com<p><em>The growing concern over environmental issues has encouraged companies to enhance transparency through environmental disclosure practices. This study aims to examine empirical findings from previous research regarding the relationship between environmental performance and profitability on corporate environmental disclosure in Indonesia. The method used is a literature review by analyzing 15 relevant journal articles published within the last five years. The results indicate that environmental performance generally has a positive effect on environmental disclosure. Companies with superior environmental management tend to be more open in presenting environmental information as an effort to enhance legitimacy in the eyes of the public. Meanwhile, the influence of profitability on environmental disclosure shows varying results, some studies find a positive relationship, others a negative one, and some report no significant effect.

This has driven world oil prices up to $100 per barrel, increasing inflation in Batam by an estimated 1.8% – 2.2%. This study aims to analyze the effect of the Rupiah exchange rate against foreign currencies (USD), where the Rupiah is currently moving in the range of Rp17,387 – Rp17,405, and the benchmark interest rate (BI‑Rate), which Bank Indonesia has maintained at 4.75% for the April 2026 period. Given Batam’s position as a free‑trade zone that is highly dependent on imports and foreign exchange flows, national macroeconomic fluctuations often have a faster impact in this region. The method used is multiple linear regression with time‑series data sourced from the Central Statistics Agency (BPS) of Batam and Bank Indonesia. The results show that partially, the exchange rate has a positive and significant effect on inflation, where Rupiah depreciation drives up the prices of imported goods (cost‑push inflation). Meanwhile, the interest rate has a negative and significant relationship with inflation in the short term, but its effect is weaker compared to the exchange rate. Simultaneously, both variables contribute 78.4% to the movement of inflation in Batam City.

The City of Batam has implemented innovations such as the Electronic Population Service application (LAKSE), yet interactive information channels capable of answering citizens' questions directly, quickly, and contextually remain limited. The development of Large Language Models (LLMs) has opened significant opportunities for building public information service chatbots; however, generic LLMs are prone to hallucination—producing answers that sound convincing but are inaccurate or inconsistent with current regulations. This research aims to design and develop an LLM-based chatbot enhanced with a Retrieval-Augmented Generation (RAG) approach to accurately answer public questions related to e-KTP issuance in the City of Batam, since the generated answers are retrieved and referenced directly from an official knowledge base such as Disdukcapil regulations, administrative requirements, and LAKSE procedures. The development method employs a software engineering approach comprising the stages of document collection and cleaning, embedding into a vector database, integration of the retrieval mechanism with the LLM, and testing of answer accuracy using semantic similarity metrics and expert evaluation.

The emergence of Industry 4.0, artificial intelligence, big data, and electronic transaction systems has improved efficiency and accessibility in modern society. However, these advancements are also accompanied by increasing misuse of technology, resulting in various forms of cybercrime such as hacking, online fraud, and other electronic-based criminal activities. This study aims to analyze the relevance of the principle of legality in the new Indonesian Criminal Code (KUHP) in addressing the evolution of digital crime in Indonesia, particularly in response to the rapid development of technology. The research method used is normative legal research with statutory and conceptual approaches, examining the new Criminal Code, the Electronic Information and Transactions Law, and relevant legal literature. The findings indicate that the principle of legality remains a fundamental doctrine in Indonesian criminal law, particularly through the application of lex scripta, lex certa, lex stricta, and lex praevia principles. However, the rapid, cross-border, and technologically complex nature of digital crime creates a regulatory gap, causing law to lag behind social reality. Although the new Criminal Code introduces the concept of living law, it has not fully addressed the complexity of evolving digital crimes. Therefore, harmonization between the Criminal Code, the Electronic Information and Transactions Law, and other sectoral regulations is required, along with adaptive legal reform, to ensure that the principle of legality remains relevant in providing legal certainty, justice, and effective law enforcement in the digital era.</em></p>2026-07-18T00:00:00+00:00Copyright (c) 2026 Prosiding Seminar Nasional Ilmu Sosial dan Teknologi (SNISTEK)https://ejournal.upbatam.ac.id/index.php/prosiding/article/view/11743MACHINE LEARNING PENDETEKSI WAJAH DENGAN OPEN CV MENGGUNAKAN PYTHON2026-06-23T03:07:17+00:00Sunarsan Sitohangssunarsan@gmail.comHotma PangaribuanSunarsan@puterabatam.ac.id<p><em>Machine learning is a branch of artificial intelligence that enables computers to identify patterns, make predictions, or take actions based on provided data.

In line with this achievement, the Indonesian government, through the Badan Penyelenggara Jaminan Produk Halal (BPJPH), ensures that food products are certified as halal. This policy requires all food business manufacturers to obtain halal certification for their products. The objective of this study is to analyse potential risks in halal food products among Small and Medium Enterprises (SMEs) to ensure the quality and integrity of halal food products. This study employed a quantitative research approach and was conducted through a case study of food SMEs in Batam City, Indonesia. The Failure Mode and Effects Analysis (FMEA) method was utilised to identify risk factors and analyse their causes, thereby preventing potential contamination that could compromise product quality and halal compliance. Primary data were collected through interviews and direct observations of production processes, while secondary data were obtained from production reports. The findings of this study indicate that 15 risks were identified in the production process. The highest risk factor was found at R04 with a Risk Priority Number (RPN) of 75, which obtained a level 1 rating and fell into the 'Very High' risk category. This risk pertains to the preparation area for the main raw ingredients for making doughnuts, which is conducted on the floor, thus posing a potential for contamination from dirt/dust. As for the recommended suggestion, it is to provide a separate storage area for the preparation zone, distinct from the dough-mixing area, so that dirt, dust, or other contaminants do not contaminate and enter the doughnut dough.
