Abstract

Many Indonesian residents have difficulty obtaining clean water, especially people who live in coastal areas. Those who live there can only consume brackish water which is considered to have side effects on health due to the excessive calcium content. This research offers a simple method, namely adsorption using abundant raw materials, namely rice husk ash from agricultural waste resulting from burning rice husks. Using husks directly has less effectiveness, so it needs to go through additional processes such as removing impurities and modifying the structure. This research aims to reduce calcium levels in brackish water using silica that has been modified from rice husk ash. The process of making adsorbents is carried out by sieving, heating, filtering, washing to obtain silica, then modifying and optimizing important parameters until its application to brackish water. The difference between pre-modified and modified silica can be seen in the characterization with FTRI at wave numbers from 470 cm-1 to 430 cm-1 1, namely deeper bending vibrations, which are also clarified by the surface condition with more structured pores seen in the SEM results. The modified silica works optimally at a mass of 0.4 grams, pH 7.5, contact time of 40 minutes and concentration of 50 ppm. It has an adsorption capacity of 3.2 mg/g and follows the Langmuir isotherm pattern.

Abstract

This study compares the representation of hedonism and the shift in thinking of characters in the films The Tinder Swindler (2022) and The Great Gatsby (2013). This study uses a qualitative descriptive method using the theory of hedonism by Epicurus (341-270 BC) as the basis for analysis. This study found that in The Tinder Swindler, hedonism is used as a tool of manipulation in the digital era, while in The Great Gatsby, hedonism reflects the search for happiness that ends tragically. Simon Leviev's character does not experience a change in thinking, still holding on to his hedonistic life principles even though he is caught, while Jay Gatsby experiences the realization that wealth cannot repeat the past. A comparison of social contexts shows that The Tinder Swindler reflects the culture of imagery on social media, while The Great Gatsby reflects the excesses of capitalism in the Roaring Twenties era. The conclusion of this study emphasizes that excessive hedonism can lead to destruction, both in the modern world and in a historical context. This study reminds us that the search for happiness through material things often ends in emptiness. Thus, this study reveals that not all forms of hedonism lead to true happiness, especially when based on the illusion of wealth and social image

Abstract

Health care is a fundamental right of every citizen guaranteed by the constitution and various laws and regulations. However, in practice there are still cases of health care malpractice that often occur, either due to negligence, carelessness, lack of competence, or violation of professional standards. Such actions not only have an impact on the physical and psychological harm of patients, but also raise questions regarding the legal responsibility of the perpetrators, especially in the criminal realm. The problems in this study are how health care malpractice in the perspective of criminal law and how criminal liability for health care malpractice. This research uses normative juridical research method with statute approach and conceptual approach. The results showed that health care malpractice must be viewed as a criminal offence that can be subject to criminal liability in accordance with the provisions in the Criminal Code, Law Number 17 of 2023 concerning Health, and other regulations.

Abstract

This study aims to examine the influence of learning models and the intensity of internet use on student learning outcomes in the subject of social studies in grade VII of MTs Prima Bekas. This study uses a quantitative approach with a pre-experimental methodology. The research sample consisted of 30 grade VII students taken through a total sampling technique. Data collection instruments used questionnaires and documentation of student achievement score. The results of the study showed that: (1) learning methods did not have a significant effect on students' academic achievement (sig = 0.226); (2) the frequency of internet use had an influence but was not statistically significant on students' academic achievement (sig = 0.087); and (3) learning methods and frequency of internet use simultaneously did not have a significant effect on students' academic achievement (sig = 0.181). The coefficient of determination (R Square) value of 0.015 indicated that only 1.5% of the variation in students' academic achievement could be explained by these two variables. Thus, there are other elements outside of learning methods and frequency of internet use that also have the potential to influence the academic achievement of social studies student

Abstract

This study explores the intersection of gendered humor, stylistic innovation, and pragmatic subversion in modern feminist theatre, focusing on works by Caryl Churchill, Sarah Ruhl, and Ntozake Shange. These playwrights employ humor not merely as entertainment but as a discursive weapon to challenge patriarchal norms, expose socio-political absurdities, and redefine gendered subjectivities. Drawing on frameworks from, stylistics, and pragmatics—particularly politeness theory, speech act theory, and incongruity theory of humor—this research investigates how stylistic choices (e.g., fragmentation, surrealism, poetic language) intertwine with humor strategy articulate feminist resistance. By analyzing selected scenes from Top Girls (Churchill), The Clean House (Ruhl), and for colored girls who have considered suicide / when the rainbow is enuf (Shange), the research reveals how humor in feminist drama functions both as a coping mechanism and as a mode of critique. This study contributes to feminist stylistics by offering a nuanced account of how gendered language and stylistic form shape subversive humor. Ultimately, it foregrounds how female playwrights turn theatrical space into a site of both laughter and liberation.

Abstract

The increase in the mobility of foreign nationals (FNs) to Indonesia, particularly through border areas such as Batam City, has given rise to various legal issues, especially related to the misuse of residence permits. This phenomenon includes overstay violations, the misuse of visit visas for illegal work, and the use of fake documents, which have the potential to disrupt public order and cause harm to the state. This study aims to analyze the legal effectiveness of law enforcement against the misuse of residence permits by foreigners in Indonesia, with a focus on a case study at the Special Class TPI Batam Immigration Office. The research method used is normative legal and empirical legal methods, with a sociological approach (socio-legal approach). Data was collected through a literature review of relevant laws and regulations, as well as through interviews and direct observations of Batam Immigration officials and personnel. This study uses the theoretical framework of State Sovereignty, Lawrence M. Friedman's Legal System, and Soerjono Soekanto's Legal Effectiveness. The results of the study indicate that although immigration regulations have provided sufficient authority to the Immigration Office, there are still significant obstacles in their implementation, such as limited human resources and facilities, weak inter-sectoral coordination, and a permissive legal culture among the community towards the presence of illegal foreign nationals. Law enforcement is predominantly administrative in nature, while criminal proceedings are rarely used due to procedural complexities. This study recommends the need for regulatory harmonization, strengthening institutional capacity and personnel, optimizing the role of the PORA Team, and enhancing public legal literacy in monitoring the presence of foreigners as strategies for reforming the immigration legal system to make it more effective.

Abstract

The Visa-Free Visit Policy (BVK) granted to foreign nationals (WNA) holding Singaporean Permanent Resident (PR) status, as stipulated in Presidential Regulation No. 95 of 2024, is part of the national strategy to encourage foreign tourist visits to Indonesia, including to Batam City as a strategic border region. However, this policy also has significant legal implications for security stability and local economic dynamics. This study aims to analyze the legal arrangements of the BVK-PR policy, its implementation in the field, and its impact on the security and economy of Batam City. The research methods used are normative legal and empirical legal, with a regulatory and sociological approach. Data was obtained through legal document studies and interviews with immigration officials, police, customs, and the Batam City Government. The theories used include John Rawls' Theory of Justice (grand theory), Lawrence M. Friedman's Theory of the Legal System (middle theory), and Sudikno Mertokusumo's Theory of Legal Certainty (applied theory). The research findings indicate that while the BVK and PR policies contribute to increased tourist mobility and economic activity, they also result in a decrease in state revenue from the visa sector and an increase in security risks such as smuggling and human trafficking. Implementation challenges were identified in the areas of ambiguous norms, weak oversight, and low legal awareness among the public. It is recommended that the BVK policy be revised with a selective approach, accompanied by strengthening inter-agency oversight structures, and legal education for local communities to maintain a balance between economic benefits and national security protection.
