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

This journal discusses the legal issues related to the disbursement of financing facilities amounting to Rp. 80,000,000,- by DEFENDANT I without any valid Mortgage Rights binding on SHM No. 34/Buladu, which resulted in the disbursement being considered invalid. Decision Number 723/PDT.G/2021/PA.Gtlo confirms that the deeds made do not meet the formal requirements and must be declared null and void by law. This study also highlights legal protection for debtors in the context of sharia economics, with a focus on fiduciary guarantees regulated in Law No. 42 of 1999. The case discussed involves the confiscation of fiduciary guarantee objects due to the debtor's default, as well as the importance of SKMHT (Power of Attorney to Charge Mortgage Rights) as a legal instrument to secure the creditor's position. This study uses normative legal methods and identifies the factors causing the debtor's default, as well as the correct procedures in issuing APHT (Deed of Granting Mortgage Rights). The results of the study indicate that there is abuse of conditions in the agreement and breach of promise by the debtor, and emphasize the importance of understanding the rights and obligations of debtors and creditors in debt agreements.

Abstract

Mangroves are vital coastal ecosystems that thrive in tidal environments and play a crucial role in biodiversity and shoreline protection. This study aims to assess the vegetation density of the Langsa City Mangrove Forest using the Normalized Difference Vegetation Index (NDVI) derived from Sentinel-2A satellite imagery and analyzed through Geographic Information System (GIS) tools, particularly ArcGIS. NDVI values were categorized into four classes: very low (-0.15–0.34), low (0.35–0.48), medium (0.49–0.61), and high (0.62–0.83). The spatial analysis revealed that 57.2% of the area (approx. 128.5 ha) exhibited high vegetation density, while 24.6% (55.2 ha) showed medium density, and 13.3% (29.9 ha) had low vegetation. Approximately 4.9% (11.0 ha) of the area was classified as very low density, indicating regions with potential for ecological rehabilitation. These findings demonstrate that NDVI is an effective and reliable indicator for monitoring mangrove vegetation health. Routine application of NDVI analysis is essential for supporting sustainable management strategies and long-term conservation planning in coastal forest ecosystems..

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 crime of forgery is a crime that contains elements of untruth or falsehood of an object that appears from the outside as if it is true, when in fact it is contrary to the real thing. This study aims to examine and analyze legal arrangements regarding the alleged forgery of Covid 19 swab certificates according to laws in Indonesia, the legal consequences committed by perpetrators of crimes related to the forgery of Covid 19 swab certificates and legal liability for perpetrators of the crime of forging Covid 19 swab certificates based on the decision of the Bitung district court Number 141/Pid.B/2021/PN Bit. This research method uses a type of normative juridical research that is descriptive analytical. The data sources obtained using secondary data are based on primary and secondary legal materials. The data collection technique used is a literature study. Legal arrangements related to alleged forgery of letters, especially doctors' certificates in Indonesia, have been regulated in the Criminal Code, especially Articles 267 and 268. Bitung District Court Decision Number 141/PID. B/2021/PN Bit emphasized that the application of criminal sanctions for falsifying Covid 19 swab certificates is a criminal conviction contained in the Criminal Code, namely article 268. The application of strict and definite punishment is urgently needed to prevent criminal behavior and provide a deterrent effect for other individuals who have the potential to commit similar acts.
