Problematic issues arising in the field of state registration of acts of civil status
Authors: Egorov V. O.
Published: September 2024

State registration of civil status acts is one of the forms of public services in the field of administrative law. The public service orientation of executive authorities and local self-government bodies is a priority in the decentralization processes which are taking place in Ukraine today. The focus of the local government reform is on people, and one of the important factors of their comfort is the provision of quality administrative services.
Every day, children are born in Ukraine, some get married, some get divorced, and some die. Despite all the difficulties that exist today, the service of state registration of civil status acts is the most popular among Ukrainian citizens.
The armed aggression of the Russian Federation against Ukraine has made many adjustments to our everyday life and the life of the country as a whole. Despite all the challenges, the legislator is trying to facilitate bureaucratic procedures, including in the field of civil registration. The latest technologies are being actively introduced, and amendments and additions are being made to the legislation in the field of state civil registration. Despite the significant progress in civil registration legislation, some difficulties arise in practice, especially in situations of state registration of marriage or divorce when one of the spouses is a military officer, or if one of the spouses is abroad, or in the area of active hostilities, or in the temporarily occupied territories of Ukraine. Regarding the temporarily occupied territories, unfortunately, during the 10 years of armed conflict, Ukraine has not been able to simplify the procedure for legitimizing civil status acts issued in the temporarily occupied territories of Ukraine. Therefore, Ukrainian citizens must go to court to recognize facts that have legal significance. Therefore, it is necessary for the legislator to resolve the problematic issues related to state registration of civil status acts.
Methods and tactics of attorney’s-at-law activities in enforcement proceedings
Authors: Zhabotynskyi I. V.
Published: September 2024

The methodology of the attorney’s-at-law activities in enforcement proceedings is defined as a set of active and proactive actions of the attorney-at-law representing a party aimed at achieving the overall goal set by his or her client in the enforcement proceedings. The tactics of the attorney’s-at-law activities in enforcement proceedings are defined as a set of tools aimed at achieving intermediate objectives by the attorney-at-law during a separate enforcement action or at a separate stage of enforcement proceedings.
The preventive methodology and tactics of an attorney’s-at-law activities are based on the ability of the lawyer to convince the client that voluntary execution of the court decision is more cost-effective and reasonable than the initiation of enforcement proceedings against him or her by the creditor. Such tools can be applied only to the initiation of enforcement proceedings by a public or private enforcement officer and are most effective in terms of saving the client’s time, financial and personal resources.
The methodology and tactics of an attorney’s-at-law activities in enforcement proceedings may consist in taking an active or passive position as a representative of a party to the enforcement proceedings, may be aimed at reaching an amicable agreement with the other party or at evading the obligation to execute a court or other authority’s decision. The last of the above positions of the attorney-at-law-representative is destructive and is being a form of abuse of procedural rights demonstrated by the attorney-at-law-representative or his/her client (typically by a debtor).
There some peculiarities of the methodology and tactics of attorney’s-at-law activities in enforcement proceedings, in particular the tools and methods used by the attorney-at-law-representative, must be: (a) conditioned by the general tasks of civil proceedings at the stage of enforcement of a court or other body’s decision; (b) bona fide, take into account the legitimate interests of the client and must not harm other parties to enforcement proceedings and/or third parties; (c) complied with applicable law and must not contain signs of offenses, in particular, in the form of abuse of procedural rights.
Obtaining evidence by the court at the request of international commercial arbitration
Authors: Rozhnov O.
Published: September 2024

The article is dedicated to the study of the legal aspects of the procedure for obtaining evidence at the request of the International Commercial Arbitration Court through national courts. The procedure for submitting evidence in international commercial arbitration depends on the rules agreed upon by the parties in the arbitration agreement, as well as the applicable procedural norms of the arbitration institution (e.g., UNCITRAL Rules, ICC, LCIA, etc.). However, there are general principles and stages that are characteristic of most arbitration processes.
The participation of national courts in relationships arising in connection with arbitration proceedings is implemented through the exercise of certain functions by the judiciary within the established scope of interaction. It has been determined that the primary goal pursued by the state, by granting national courts the authority to perform functions of assistance and control, is an interest in the implementation of the international commercial arbitration jurisdictional function. These circumstances ensure the effectiveness of arbitration proceedings and their attractiveness for the disputing parties.
The general rules for submitting evidence and the powers granted to international commercial arbitration are highlighted, which include the authority to determine the admissibility, relevance, materiality, and significance of any evidence.
It is concluded that the general rule is that the international arbitration court has the right to require the parties to submit evidence, as well as the right to request evidence from third parties, which the arbitration tribunal deems necessary for the resolution of the dispute.
It is noted that an effective way to obtain the requested evidence is provided by Article 27 of the Law of Ukraine «On International Commercial Arbitration,» which allows the arbitration court to apply to the national court for assistance in obtaining evidence by way of a request for evidence.
It is argued that the court’s assistance in obtaining evidence within the context of Article 27 of the Law of Ukraine «On International Commercial Arbitration» should only be considered in the possibility of requesting evidence by the court in accordance with Article 84 of the Civil Procedure Code of Ukraine. The request for evidence, as part of the institution of evidence preservation, in accordance with part 7 of Article 116 of the Civil Procedure Code, is not a form of court assistance to international commercial arbitration, which involves not only obtaining evidence relevant to the subject matter of the case and important for its resolution, but also primarily a way to prevent its potential loss in the future.
Reception of Roman Private Law in Ukrainian Civil Law as Confirmation of Belonging to the European Legal Family
Authors: Petronchak Yu. O. , Romaniv Kh. B.
Published: September 2024

The article is devoted to current issues of civil law, as well as Roman private law in Ukraine. The purpose of the article is to trace the influence of Roman private law on the development of civil law. In the course of the research, a number of general scientific and special methods of cognition were used, including: historical, dialectical, comparative-legal, logical analysis, formal-legal and other methods.
Our legal culture has received Roman law, which became the basis for civil law and is still reflected in modern Ukrainian legislation. In the course of the study, it was established that the Civil Code of Ukraine contains articles that are evidence of both direct and indirect reception. Direct reception occurs when the ideas and provisions of Roman private law are transmitted directly from the primary sources of Ancient Roman law. Indirect (derivative) reception occurred when Roman legal ideas and legal solutions were borrowed not directly from primary sources, but through those legal systems where reception had occurred earlier. That is, indirect reception is the perception of the law of other states where this process has already taken place, and not directly through the primary source.
We can affirm the successful reception of Roman law in Ukraine through the basic principles of law, moral and social values, which became the basis of the legal provisions of Roman law and the achievements of human social culture. Therefore, the achievements of Roman law are not only in the formation of civil law in Ukraine, but also in the ability to expand legal thinking and respect for law as a value and the main achievement of society.
It can be unequivocally stated that civil law, being part of the Romano-Germanic legal system, is a reproduction of Roman private law, which on the one hand, through centuries-old transformation, has acquired a corresponding theoretical content and remains unchanged and relevant to this day.
The conclusions obtained during the study of the influence of Roman private law on the development of civil law as a whole develop both the theory of civil law and the philosophy of law and serve as a subject for further research on the genesis of civil law institutions, the origin and essence of most legal norms in Ukrainian civil law.
Peculiarities of fulfilling obligations under a timeshare agreement
Authors: Fathutdinova I. V.
Published: September 2024

The scientific article examines established approaches in private law doctrine to understanding the concept of «fulfillment of contractual obligations». The essence of the fulfillment of obligations is revealed, in particular, that it is revealed through those actions that the party commits to achieve the results for which the deed was concluded.
It has been proven that active fulfillment of obligations takes place in timeshare contracts, as actions are assumed by both counterparties, the consumer must pay on time, and the timeshare founder must provide access to property suitable for quality recreation during the reserved period. It was found that the fulfillment of obligations under the timeshare agreement: aims to achieve the purpose of the timeshare agreement; is a manifestation of consistent factual and legal actions of the parties to the contract, which, on the one hand, achieve the goal, and on the other hand, provide for the exercise of subjective rights.
It is justified that the principle of good faith plays an important role in fulfilling the obligations under the timeshare agreement, which is the appropriate standard of actions of the parties to the agreement, a measure of honesty, openness, and respect for the interests of the counterparty. A timeshare contract will be properly executed if the parties to the contract act in good faith.
It was found that good faith is closely related to the principle of obligation of the parties to fulfill their contractual obligations, which definitely limits the freedom of contract. This is also followed in judicial practice. In addition, good faith helps prevent possible abuses of contractual freedom.
Fulfillment of obligations under the timeshare agreement must be proper, which is directly related to the will of the parties, as well as the quality of the provided services for accommodation for recreation of the consumer and his family members. In our opinion, the quality of services under timeshare contracts should be one of the essential conditions of the contract, the feature that characterizes its subject.
It was revealed that when considering the problem of proper performance of the obligation, scientists also note the principle of real performance, which means the need for the debtor to perform those actions that correspond to the content of the obligation.
The legal status and activities of the authorities of the Ukrainian People’s Republic in exile (end of 1920 – August 22, 1992): historical and legal aspects
Authors: Dzeiko Zh. O.
Published: September 2024

A historical and legal study of the legal status and activities of the authorities of the Ukrainian People’s Republic (hereinafter - the UPR) in exile (late 1920 – August 22, 1992). It is concluded that, since at the end of 1920 the authorities of the UPR lost influence on the population as a result of the establishment of Soviet power in most of the Ukrainian territories and the UPR actually ceased to exist, which was formally fixed by a peace treaty between the Polish-Lithuanian Commonwealth and Soviet Russia on March 18, 1921. in Riga, the UNR authorities lost their state status and acquired public status. The content adopted by the Council of People’s Ministers and approved by the Chairman of the Directory on January 9, 1921 was analyzed. a normative act entitled “Law on the Council of the Republic,” in which the Council of the Republic was defined as “a temporary supreme authority of the people, which has full power.” The authorities of the UPR imitated state activity: the Council of the Republic – as legislative, the Council of People’s Ministers - as executive authority, the Head of the Directory – as the head of the UPR. After the termination of the existence of the Council of the Republic in August 1921 the functions of the UNR authorities in exile were carried out by the Head of the Directory and the Council of People’s Ministers. The content of the “Temporary Law on the Reorganization of the State Center of the UNR in Exile” of June 10, 1948, which established the competence of the constituent parts of the State Center of the UNR: President, Vice-President, Government, Ukrainian National Council, was studied. Based on the analysis of the content of this normative act, it was concluded that the State Center of the UPR in exile formally had the status of a public organization, but pretended to be a state authority and imitated state functions. According to this document, the Ukrainian National Council performs “the functions of a temporary legislative representation.” The relationship between the constituent parts of the State Center of the UPR in exile had to be revealed in the rule-making process and in the formation of the Government. The political responsibility of the Government to the Ukrainian National Council and the President of the UPR was envisaged. The Government’s accountability to the Ukrainian National Council and control over the UNR President were established. The UNR President was vested with the right to dissolve the Ukrainian National Council at the suggestion of the Government. The authorities formed on the basis of this normative act had the status of public and performed functions in international, normative, political, scientific and other spheres.
The national idea in the Ukrainian legal area
Authors: Vasyliev Sergii
Published: September 2024

The study is based on the assumption that at the current stage of development of the State and society, there is a need to form a national idea of the State, which is a theoretical expression of the Ukrainian people's self-awareness of their identity and individuality, and which, based on common values and interests, can be one of the important factors in consolidating Ukrainian society, a general vector for further development of the country and a guideline for its role and place in the world community. The national idea is an expression not only of the psychological and cultural model of society, but also a manifestation of the national legal sphere, which has a complex and ambiguous composition that requires a detailed scientific study. The purpose of the study is to identify the prerequisites and components of the formation of the national idea at the current stage of development of Ukrainian society and the State in the legal plane. The theoretical basis of the study is based on analytical developments in the theory of state and law, political science, constitutional law, and sociology of law in the study of various aspects of the national idea in the context of globalization. Numerous tasks and the diversity of the material under study have led to the use of various research methods: formal legal, systemic and structural, specific sociological, logical. The work uses the socio-cultural and civilizational approaches to the analysis of legal ideology, legal policy, legal doctrine, as well as axiological, geopolitical, and institutional approaches to the national idea of the State. It is noted that when forming the national idea, laying a progressive national-state ideology as its basis, it is necessary to take into account both the cultural uniqueness of Ukraine and the legal component of society, as well as global trends in the modern world. In the context of state-building, the national idea should be an integrative ideological basis on which to consolidate the political nation and create a project for the country's development for the future. It can be argued that the modern state-building process in Ukraine requires modernization of the concept of the national idea and certain adjustments to its value content. In order for the national idea to become an effective basis for the development of the rule of law, it must be correlated with legal ideology, legal policy and legal doctrine, and must be consistent with such values as national interest and national mentality. The implementation of the national idea should have a specific content and be filled with practical steps in the development of the Ukrainian state.
The Religious Cognition: A Meta-Analysis Study of Indonesian Students' Religious Learning Achievement
Authors: Mistiani Wiwin
Published: September 2024

The large number of published studies related to religious learning achievement in the cognitive domain certainly raises questions in the minds of research users, especially if the conclusions produced vary from one study to another. Therefore, to find out the average of students' religious learning achievement in Indonesia on the cognitive aspect, it is necessary to carry out a meta-analysis. The meta-analysis in this study aims to determine the average effect size of the aggregate Islamic learning achievement of students in Indonesia. This research uses a quantitative approach using meta-analysis. Research data was collected from various studies including journal articles, theses and student theses from 2009-2023 which were obtained through internet searches using the keyword Islamic learning achievement. The results of the research show that the average Islamic learning achievement of Indonesian students is 83.00 with a standard error of the weighted random model of 1.526 with a combined average score of 80.05 and an upper limit of 85.95. This shows that the ability/achievement in learning the Islamic religion of Indonesian students at the elementary to middle school levels has exceeded the minimum completeness, namely 75. Based on the Regression Method and Trim and Fill analysis, it was found that there was no publication bias. So the conclusions made based on the random effect model regarding the average cognitive abilities of students are valid.

Published: September 2024

This scientific study aims to thoroughly assess the current status and evaluate key indicators influencing healthcare and the workforce in selected European Union (EU) member states. Building upon this ambitious research agenda, we focused on a comprehensive descriptive analysis of selected indicators within the healthcare sector, including healthcare financing schemes, overall employment in healthcare and social care, the number of graduates in healthcare (including physicians and general practitioners), as well as migration patterns within the healthcare sector. The data forming the basis of this analysis were systematically gathered from Organization for Economic Co-operation and Development (OECD) and Eurostat databases. Subsequently, we conducted a robust correlation analysis to explore the intricate relationships among these indicators. Our research endeavour aimed to identify and quantify the impact of these indicators on each other, with a focus on their implications for overall healthcare and the workforce in the respective countries. Based on the findings obtained, we derived several significant conclusions and recommendations. For instance, we identified that increasing employment in the healthcare sector may be associated with the overall quality of healthcare provision in a given country. These findings have important implications for policymaking and decision-making at the EU level. Therefore, we recommend that policymakers in these countries consider implementing measures to further develop the healthcare sector while also helping to retain and attract qualified professionals in the healthcare industry. Such recommendations could include improving healthcare infrastructure, incentivizing professional education and further training in the healthcare sector, and implementing policies to support healthcare provision more broadly.

This study aims to develop and validate a strategic model tailored to the unique challenges and contexts faced by micro, small, and medium-sized enterprises (MSMEs) in Ecuador, enhancing their operational efficiency and access to financing. Employing a quantitative approach, the research utilized a non-experimental, cross-sectional design to gather data from a sample of 358 companies. The study revealed that MSMEs are significantly hindered by limited access to financing, lack of managerial skills, and technological gaps. Despite these challenges, MSMEs demonstrated considerable adaptability and resilience, underscoring their critical role in the local economy. The strategic model proposed leverages Porter’s Diamond Model to identify and address the specific competitive and operational challenges encountered by these enterprises. Key findings include the necessity for enhanced financial literacy, simplified regulatory frameworks, and the integration of digital technologies to improve competitiveness. The proposed model focuses on strategic training, fostering innovation, and creating a more supportive financing environment. The implications of this study are profound, suggesting that policymakers and practitioners should streamline regulatory processes, enhance financial and technological support frameworks, and provide tailored training programs. These strategies are intended to bolster the sustainability and growth of MSMEs, contributing to broader economic development. This research contributes to the academic literature by providing empirical evidence on the challenges faced by MSMEs in developing economies and proposing a contextually adapted strategic model to mitigate these challenges, thereby enhancing their economic impact and sustainability.

Disability inclusion is important to ensure everybody has the same opportunities in society, which is critical in achieving the Sustainable Development Goals. Persons with Disabilities (PWDs) are one of the marginalized communities and most of them are living in poverty. Disabilities encounter many challenges internally and externally due to their disabilities. They are struggling to keep their jobs due to their own self-confidence and social stigma and entrepreneurship is said to be the best option for PWDs to gain economic liberation. However, many PWDs still depend on government assistance and public donations instead of starting their own business. This study investigates the mediating effect of entrepreneurial motivation on the relationship between internal and external factors of PWDs’ perceptions of entrepreneurship in Malaysia. A quantitative approach to the survey was carried out. A sample of seventy-seven PWDs was gathered using face-to-face and online surveys through purposive sampling. The data were analyzed using structural equation modelling. The results show that only internal factors influence PWDs’ entrepreneurial personal perception. Entrepreneurial motivation plays a crucial mediating role in the relationship between internal and external factors and entrepreneurial personal perception. The study is helpful for the relevant parties to assist PWDs in becoming financially independent through entrepreneurship by focusing more on their internal strengths. Proper training and coaching assist PWDs in being more resilient when facing adversity.

Z-K-R: A Novel Framework in Intrusion Detection system through enhanced techniques
Authors: Sandosh S. , Bala Akila , Kodipyaka Nithin
Published: September 2024

Intrusion detection systems (IDS) are an important tool for securing computer networks from various types of cyberattacks. The increasing complexity of network attacks demands more sophisticated approaches to intrusion detection. This paper presents an innovative method for IDS that involves combining Z-Score outlier detection, KMeans clustering, and Random Forest classification techniques. We tested our methodology using the CICIDS2017 dataset, which is a standardization dataset for intrusion detection that is frequently utilized. Our proposed approach first uses Z-Score outlier detection to identify abnormal traffic flows in the network. Next, KMeans clustering is used to group the traffic flows into different clusters based on their similarity. Finally, Random Forest classification is used to classify each traffic flow into normal or abnormal categories. Based on our experimental results, our approach for intrusion detection shows superior performance compared to several other state-of-the-art methods in terms of accuracy and precision. Our proposed method achieved an accuracy rate of 95.75% and a precision of 95.76%, surpassing the performance of KNN, SVM, and decision trees approaches. In conclusion, the proposed Z-K-R approach offers a promising solution for IDS by leveraging the strengths of Z-Score outlier detection, KMeans clustering, and Random Forest classification techniques. This strategy has the potential to increase the efficiency of IDS and boost network security in applications that take place in the real world.
Artificial Intelligence, Fintech and Challenges to Central Banks

Published: September 2024

Technological development particularly boosted by artificial intelligence (AI) has substantial potential to transform many aspects of human lives and the way doing businesses. On the one side, it can offer opportunities, while on the other brings challenges and increases risks. Financial industry is considered the largest user of digital technologies and provider of innovative services. Therefore, it is strongly influenced by digital transformation and under constant threat of cyberattacks. In this paper, the authors are researching the opportunities and risks stemming from the application of AI and its macroeconomic and financial system impacts. The special attention is given to the challenges posed by financial technological development and AI to central banks as they have to adopt to the novel times dominated by electronic financial services and AI tools while at the same time stay persistently dedicated to achieving their key objectives of safeguarding monetary and financial stability as well as contributing to the stability of economic growth. Additionally, the invention of generative artificial intelligence (GenAI) has significantly influenced processes throughout numerous industries, including the financial sector, due to the ability to imitate human behaviour which has enabled computers to behave like humans. Hence, it is important to develop human-centric innovations where AI tools create benefits and serve people instead of replacing them. AI can deteriorate overall inequality so policymakers should act towards developing policies that will ensure AI is used for the good of people and provide benefits for them. The authors further draw attention to the necessity of adopting a robust regulatory framework and building strong and resilient institutions with developed systems for prevention of ever raising cyberattacks.

Introduction

Ticks are obligate blood-feeding arthropods that cause significant economic losses in domestic animal husbandry and threaten public health. However, information about soft ticks (Acari: Argasidae) and tick-borne pathogens in the Xinjiang Uygur Autonomous Region (XUAR) of China is scarce.

Material and Methods

In this study, PCR assays and gene sequencing were used to detect and analyse the epidemiological features of Anaplasma ovis, Theileria ovis and Brucella abortus parasitic infections in 366 Ornithodoros lahorensis soft ticks collected from five sampling sites in the XUAR from October 2019 to March 2022. The ticks were identified by morphological and molecular methods as O. lahorensis. The PCR was conducted using primers complementary to the major surface protein 4 (Msp4) gene of A. ovis, the 18S ribosomal RNA (18S rRNA) of T. ovis and the outer membrane protein 22 (Omp22) gene of B. abortus.

Results

The overall infection rate was 91/366 (24.9%) for A. ovis, 127/366 (34.7%) for T. ovis and 94/366 (25.6%) for B. abortus. Sequencing analysis indicated that A. ovis Msp4, T. ovis 18S rRNA and B. abortus Omp22 genes from XUAR isolates showed 99.58–100% identity with documented isolates from other countries.

Conclusion

This study provides fundamental evidence for the occurrence of A. ovis, T. ovis and B. abortus in O. lahorensis. Therefore, the potential threat of soft ticks to livestock and humans should not be ignored. This study expands the understanding of the existence of tick-borne pathogens in O. lahorensis and is expected to improve the strategies for prevention and control of ticks and tick-borne diseases in China.
A Novel Approach to Wave Energy Conversion Using CFD Technique
Authors: Abbas Nawar , Barbahan Michel , Kabrial Yako , Kabrial Admoun
Published: September 2024

This article details the development and evaluation of a novel wave energy converter (WEC) aimed at efficiently capturing wave energy for electricity production. The study employs Computational Fluid Dynamics (CFD) techniques, specifically the URANS method and the k-ω SST turbulence model, to solve the Navier-Stokes equations and capture the free surface using the Volume of Fluid (VOF) model. The CFD results are validated against experimental data to ensure accuracy. Various design parameters of the proposed device were tested, revealing that the arms and bottom angle significantly affect its performance. Unlike the floating Wave Dragon (WD) device, which utilises potential energy and is set in deep water, the new fixed-seabed device is positioned in the transitional wave region near the shore, where waves retain 80% of their energy. It can be constructed from environmentally friendly cement, making it resistant to hurricanes and suitable for any wave turbine in the open sea. The MP687 turbine was used to capture the wave energy in the proposed device, testing its performance in three positions: in the open sea, in the middle of the device, and at the device’s outlet. The results show that the device significantly enhances wave energy concentration, especially when the turbine is placed at the outlet. The proposed device offers numerous advantages, including its fixed position in a high-energy wave zone, the efficient use of turbulent kinetic energy, and robust construction that can withstand storms.
Active Diagnostic Experimentation on Wind Turbine Blades with Vibration Measurements and Analysis
Authors: Korczewski Zbigniew , Rudnicki Jacek
Published: September 2024

This paper deals with the key operational problems of wind turbosets, especially offshore, where vibrations are generated by rotor blades, as a consequence of erosive wear or icing. The primary causes of the imbalance of wind turbine rotors have been characterised, the observable symptoms of which include various forms of vibrations, transmitted from the turbine wheel to the bearing nodes of the power train components. Their identification was the result of an active diagnostic experiment, which actually entered the aerodynamic-mass imbalance of a turbine rotor into a wind power train, built as a small scale model. The recording of the observed monitoring parameters (vibration, aerodynamic, mechanical and electrical) made it possible to determine a set of symptoms (syndrome) of the deteriorated (entered) dynamic state of the entire wind turboset. This provides the basis for positive verification of the assumed concept and methodology of diagnostic testing, the constructed laboratory station and the measuring equipment used. For this reason, testing continued, taking into account the known and recognisable faults that most often occur during the operation of offshore wind turbosets. Transferring the results of this type of model research to full-size, real objects makes it possible to detect secondary (fatigue) damage to the elements transmitting torque from the wind turbine rotor to the generator early, especially the thrust bearings or gear wheel teeth.

Klausul baku dalam usaha laundry ialah upaya pelaku usaha untuk meminimalkan tanggung jawab kepada konsumen. Penjelasan Pasal 18 ayat (1) UUPK menyebutkan maksud pelarangan pencantuman klausul baku yaitu agar kedudukan konsumen sejajar dengan pelaku usaha berdasarkan asas kebebasan berkontrak. Penelitian ini terfokus pada dua permasalahan yaitu perjanjian baku jasa laundry dikaitkan dengan UUPK di Kota Pekanbaru, serta, pengaturan hak dan kewajiban para pihak dari perjanjian baku yang dibuat oleh Badan Usaha Laundry dihubungkan dengan perlindungan konsumen dan Tanggung Jawab Pelaku Usaha Laundry terhadap Konsumen Pengguna Jasa Laundry di Kota Pekanbaru. Penelitian hukum sosiologis ini dilakukan dengan cara survei menggunakan wawancara dan kuesioner. Hasil penelitian ini menyimpulkan bahwa terdapat beberapa ketentuan perjanjian baku oleh pelaku usaha laundry yang menyatakan adanya pengalihan tanggung jawab yang bertentangan dengan UUPK Pasal 18. Lebih lanjut, pengaturan hak dan kewajiban antara pelaku usaha dan konsumen tidak sesuai dengan UUPK karena antara konsumen dan pelaku usaha sama-sama tidak memahami dan mengetahui apa saja yang menjadi hak dan kewajibannya masing-masing. Tanggung jawab pelaku usaha terhadap konsumen dalam kondisi ini merupakan sebuah ketidakseimbangan sangat merugikan konsumen.
