King Royal Hotel Restaurant still applies manual sales transaction recording, causing data management and revenue report preparation to be less than optimal. This study aims to design and implement a Flutter-based sales and revenue reporting application that utilizes local storage as a data storage mechanism on the device. The system development method used is the Waterfall method, which includes the stages of requirements analysis, design, implementation, testing, and maintenance. The application was developed using the Flutter framework with the Dart programming language and utilizes the shared_preferences and hive packages for local data management on the device without requiring an internet connection or external database server. In addition, the application is designed to be easy for restaurant employees to use in recording daily transactions more quickly and accurately. Testing was conducted using the Black Box Testing method, which showed that all application features functioned according to functional requirements. The results of the study indicate that the Flutter-based application with a local storage approach is capable of improving transaction recording efficiency and generating revenue reports automatically at King Royal Hotel Restaurant.

This study aims to analyze the implementation of spatial planning regulations in the development of tourism accommodations and law enforcement against spatial planning violations in the Bingin Beach area, Badung Regency. The rapid development of tourism in the area has encouraged the construction of various facilities such as villas, hotels, and restaurants, some of which are located in coastal areas and do not fully comply with spatial planning and licensing regulations. This study uses empirical legal research methods with a legislative approach, case approach, and legal sociology approach. Data was obtained through observation, interviews, and document studies, then analyzed qualitatively. The results show that the implementation of spatial planning regulations in Bingin Beach has not been optimal because there are still tourism accommodation buildings that violate zoning and coastal boundary line regulations. This condition is influenced by weak supervision, rapid tourism development, and lack of compliance with licensing procedures. Law enforcement is carried out by the local government through the imposition of administrative sanctions and efforts to control buildings that do not comply with spatial planning. This law enforcement aims to maintain order in the use of space and protect the sustainability of the coastal environment.

The role of accounting in supporting the smooth execution of management tasks is very prominent, particularly in the planning and control functions. Accounting is able to provide financial information that is presented in the form of financial statements. Financial statements are considered fairly presented when they are prepared in accordance with the provisions of PSAK; the characteristics of such financial statements must be understandable, relevant, reliable, and comparable. In the preparation of financial statements, there are rules for recording transactions, which are known as the double-entry bookkeeping system. This system is commonly and widely used in the preparation of financial statements. However, financial statements in restaurant businesses in the city of Surabaya are prepared using a single-entry bookkeeping system. Theoretically, when financial statements are prepared using a single-entry system and the existing records do not show a complete summary of transactions, many specific difficulties will be encountered in preparing accurate financial statements. In addition, there is no direct way to determine whether the balances are correct, thus posing the risk of bias, inaccuracy, and misinterpretation, resulting in financial statements that do not comply with financial accounting standards. This condition motivated the author to conduct research on restaurant businesses in the city of Surabaya. In this study, the researcher restated the financial statements of restaurant businesses in Surabaya for the years 2023, 2024, and 2025 using the double-entry system, and presented them in accordance with the provisions of PSAK No. 1 concerning the Presentation of Financial Statements. 

Trademarks not only serve as product identities but also represent the reputation and trust built by a company over the long term. In increasingly fierce global competition, legal protection for brands, especially well-known brands, is crucial. This study examines the legal implications of alleged trademark infringement by the Louis Vuitton Dak restaurant in Korea, which resembles the luxury brand Louis Vuitton. The purpose of the study is to analyze the application of Law Number 20 of 2016 concerning Trademarks and Geographical Indications and to assess the effectiveness of law enforcement against such violations. The method used is normative juridical with a statutory and conceptual approach. The analysis focuses on similarities in principle, the element of bad faith in trademark registration, and violations of exclusive rights to well-known brands. The results of the study indicate that although regulations have provided protection, law enforcement in practice still faces various obstacles and has not fully created a deterrent effect.

The obligation to consume halal food is a fundamental right of Muslim consumers, guaranteed by Islamic principles and Indonesian positive law. However, in practice, many food business operators still distribute products that have not obtained halal certification, resulting in legal uncertainty and potential material and immaterial losses for Muslim consumers. This study aims to analyze the forms of legal protection available to Muslim consumers regarding food products that are not halal-certified and to examine the responsibility of business actors as well as the role of the government in ensuring halal food compliance in Indonesia, using Sushi Go Restaurant as a case study. This research applies a normative juridical method with a statutory and case approach, supported by library research of primary, secondary, and tertiary legal materials. The findings indicate that legal protection for Muslim consumers has been comprehensively regulated through Law Number 8 of 1999 on Consumer Protection and Law Number 33 of 2014 on Halal Product Assurance. Nevertheless, the implementation of these regulations remains inadequate, particularly in terms of supervision and law enforcement against non-compliant business actors. The absence of halal certification and insufficient disclosure of halal information at Sushi Go Restaurant potentially violates Muslim consumers’ rights to legal certainty and accurate information. Therefore, stronger regulatory enforcement, improved supervision, and increased awareness among business actors and consumers are essential to ensure effective legal protection for Muslim consumers.

This study aims to design, implement, and compare the performance of the Backpropagation algorithm from Artificial Neural Networks and the Seasonal Autoregressive Integrated Moving Average (SARIMA) model in predicting the optimal daily rice requirement at Grillme Restaurant in Pontianak. The main problem faced by the restaurant is the uncertainty in determining the required daily rice stock, which periodically results in either understocking (shortage) or overstocking (wastage), leading to operational losses. To address this, the study utilizes historical daily rice sales data from January 2023 to April 2025 as the database for training and testing both predictive models. The SARIMA approach is employed to capture time series components (trend and seasonality), while Backpropagation is utilized to model non-linear patterns. Comparative test results indicate that the SARIMA model achieved superior accuracy compared to the Backpropagation model. This is confirmed by the Mean Absolute Percentage Error (MAPE) value of the SARIMA algorithm being 17.35%, which is lower than the MAPE value of Backpropagation at 19.62%. The MAPE values obtained by both models demonstrate good predictive capability, but it is concluded that SARIMA is more recommended for a more efficient and planned management of rice stock at Grillme Restaurant in Pontianak.

The development of information technology has encouraged restaurants and cafés to function not only as dining places, but also as venues for hosting various events. However, the event reservation process at Rumah Makan Ny. Hartini and Café Rain is still carried out manually through logbooks, telephone calls, and WhatsApp, resulting in problems such as unorganized data, delayed confirmations, and miscommunication with customers. In addition, the manual system limits access to information regarding venue availability, reservation schedules, and additional facilities required by customers. This study aims to develop a web-based event reservation information system using the prototyping method. The system design was carried out using Unified Modeling Language (UML), including use case diagrams, activity diagrams, and class diagrams to model user interactions, process flows, and system structure. The results of the study show that the developed system is able to automate the reservation process, customer data recording, reservation confirmation, schedule management, and additional facilities management. This system improves operational efficiency, data accuracy, and service quality, while also making it easier for customers to make reservations independently and obtain information quickly and accurately.

Tulungagung Regency has the potential for culinary tourism that can be developed, one of which is traditional culinary. Although the Tulungagung Regency Government has presented a "Halal Culinary Area" and a "Pinka Culinary Tourism Area", the area has not fully provided an interesting visual and functional experience. Therefore, it is necessary to design a space that facilitates traditional culinary MSMEs as well as an educational and recreational place. This design carries the theme of contemporary tropical architecture by considering local climatic conditions, through the application of wide openings, cross ventilation, wide trellises, and the use of natural materials, as well as expressive styles with the shape of a rooster roof and the basic shape of an elliptical building as a symbol of adaptation to climate change and the economy in the business environment. The facilities in this design include traditional restaurants, educational bales, wiyata offices, prayer rooms, playgrounds and other supporting facilities that can attract the interest of the community and introduce traditional Tulungagung culinary.

This study aims to evaluate the effects of profitability, leverage, liquidity, and cash-flow shocks on the financial distress of companies in the hotel, restaurant, and tourism subsector listed on the Indonesia Stock Exchange during the period 2021 to 2024. The research approach employed is quantitative, using logistic regression analysis. The data analyzed are secondary data obtained from the annual financial statements of the respective companies. The results of the study indicate that, simultaneously, the four independent variables significantly influence financial distress. However, based on partial testing, each variable, namely Return on Assets (ROA), Debt to Equity Ratio (DER), Current Ratio (CR), and cash flow shock, does not show a significant relationship with financial distress. These findings imply that the risk of financial distress in this industry cannot be explained solely through a single financial indicator; instead, a more holistic approach is required. This study provides essential contributions to both management and investors in assessing companies' financial condition and formulating appropriate strategic decisions.

Café retrorika is one of the cafes located in Batu City, Malang, which adopts a green marketing concept with a unique aesthetic touch, combining the concepts of “Retro” and “Eco-friendly”, where almost all of the café’s furniture and decorations are made from recycled materials, such as old windows, used motorcycle tanks, gas cylinders and rims, which are transformed into high-art decorative elements. Awareness of the importance of sustainable business is growing, including in the culinary sector. Cafes and restaurants now compete not only in terms of taste and service but also in their commitment to environmentally friendly concepts. Moreover, today’s consumers are increasingly selective in choosing places to eat that support local products, use environmentally friendly materials, and strive to reduce plastic waste. This is one of the reasons for building cafes with different concepts, as done by the owner and founder of Retrorika café. This study uses a qualitative approach with a case study research type. Data collection techniques include participant observation, interviews and documentation. The result show that Retrorika café was built based on the personal idealism of its owner as a green movement activist, rather than market calculations. The café’s “Retro” identity serves as physical evidence of sustainability practice through the use of used furniture while also creating a nostalgic experience. Its marketing strategy focuses on education through the Re-dukaci program, Retrorika goes to Halokes and Sa-Si-Su as an effort to prove the authenticity of green practices and mitigate greenwashing. These results can be concluded that the founder’s passion shapes the Green Corporate Identity and becomes a source of sustainable competitive advantage that is difficult to imitate.
