Divorce often creates new problems, one of which is related to child custody and visitation rights for parents who do not have custody. Prohibiting visitation by the custodial parent not only violates the rights of the non-custodial parent, but also disregards the child's right to receive affection from both parents. The purpose of this study is to examine the types of legal protection available to non-custodial parents who are prohibited from seeing their children. This study uses a normative legal research method with a statutory approach. Data collected from interviews with legal practitioners and parties who have experienced similar problems are included in this study. The results show that prohibiting parents who have custody from meeting their children is against the law and contrary to the principle of the best interests of the child. Parents who do not have custody rights can file a lawsuit to revoke custody rights, as stipulated in SEMA No. 1 January 2017. This study emphasizes the importance of the law in balancing the rights and obligations of parents after divorce for the best interests of the child.

William Shakespeare’s drama Antony and Cleopatra illustrates various aspects of hedonism, especially in the pursuit of love, power, and desire. These behaviors are reflected in the way the characters prioritize personal pleasure over political duty, showing how immediate gratification often clashes with responsibility. This study aims to explore the different types of hedonism represented in the play. A qualitative descriptive approach is used to analyze the dialogues and actions of the main characters, Mark Antony and Cleopatra, based on Weijers’ (2012) framework. The results reveal six categories of hedonism: folk hedonism (30%), value/prudential hedonism (20%), motivational hedonism (15%), normative hedonism (12.5%), utilitarian hedonism (12.5%), and egoist hedonism (10%). Among these, folk hedonism is the most dominant, particularly in Antony and Cleopatra’s pursuit of love and passion without considering the consequences for their political roles. The research shows that Antony and Cleopatra reflects how the pursuit of personal pleasure can shape character development, create conflict, and even lead to tragedy, illustrating timeless patterns where short-term desires overshadow long-term responsibilities.

The concept of supremum is fundamental in real analysis and plays a crucial role in the optimization of single-variable real functions. In practice, not all functions attain their supremum explicitly, which necessitates numerical approaches to evaluate their behavior computationally. This study aims to analyze the supremum of several one-dimensional real functions with different characteristics using a grid-search method implemented in Python. Four functions were examined: a parabolic function, a rational function with a sharp peak, a discontinuous piecewise function, and a function with a vertical asymptote. The analysis involved modeling the functions, discretizing the domain, performing numerical approximation of the supremum, verifying the results against analytical values, and using graphical visualization to observe the function behavior near the supremum. The findings indicate that the supremum of the parabolic, rational, and piecewise functions can be accurately identified, with results consistent with analytical expectations despite minor deviations caused by grid resolution limitations in the rational function. Meanwhile, the function with a vertical asymptote yields an unbounded supremum, which cannot be attained within the domain. These results demonstrate that Python provides stable and reliable numerical estimates of the supremum across various types of one-dimensional real functions, validating the effectiveness of computational methods in supporting conceptual understanding of supremum.

In the investment world, stock returns are the leading indicator of a company’s performance and the basis for investor decision-making in the capital market. Fluctuations in stock returns reflect market expectations of the company’s prospects. The retail sector in Indonesia is facing significant pressure from post-pandemic shifts in consumer behavior and increased competition. This study aims to analyze the effect of financial distress, company size, liquidity, operating cash flow, and accounting profit on stock returns in retail sub-sector companies listed on the Indonesia Stock Exchange (IDX) during the period 2021 to 2023. This type of research is causally associated with a quantitative approach. The data used is secondary, in the form of financial statements from retail companies. The sampling technique used was purposive, yielding a total of 39 data points from 13 retail companies. Data testing was carried out using SPSS version 24. The results showed that partially, the variables of financial distress, company size, liquidity, and accounting profit had no significant effect on stock returns. Meanwhile, operating cash flow positively impacts stock returns. These findings indicate that fundamental indicators are not always the main determinants of stock returns. Therefore, investors are advised also to consider external factors such as market sentiment, macroeconomic conditions, and government policies that may have a greater influence on stock performance in the capital market.

Islamic boarding schools (pesantren) play a strategic role in shaping the character and noble character of the younger generation amidst the increasingly sophisticated currents of modernization and digital challenges. This study aims to examine the process of character formation of students' noble character through habituation of attitudes at the Muhammadiyah Ibnu Juraimi PPTQ, as well as to understand the strategies, challenges, and roles of various parties in supporting this character development. The research method used is a qualitative approach with a case study type, through participatory observation, in-depth interviews, and documentation. The results of the study indicate that habituation of attitudes is the main strategy, which is realized through teacher role models, enforcement of discipline, routine worship such as qiyamullail, sunnah fasting, recitation of the Qur'an, and social habits such as respect and the use of Islamic greetings. The main challenges in implementing guidance are differences in student backgrounds, the motivation of administrators who still lack awareness in guiding children, and the negative influence of gadgets. Efforts to resolve this are carried out by limiting gadget access, strengthening role models, and involving students' guardians in supporting children's development. The conclusion of this study confirms that the formation of noble character is a long process that requires consistent habituation, contributions between teachers, students, administrators, and guardians of students, as well as overcoming external challenges wisely.

This study aims to analyze and compare the price responsiveness of broiler chicken meat and native chicken meat in relation to household consumption patterns in Tarogong Kidul District, Garut Regency. A quantitative approach was employed using simple linear regression analysis based on primary data obtained through observations and interviews conducted in traditional markets. The analysis examines the extent to which price changes influence the demand for both commodities. The results indicate that broiler chicken shows a very strong relationship between price and demand, reflected in an R² value of 0.963. Statistical testing further demonstrates that price has a significant effect on broiler chicken demand (0.018 < 0.05), indicating that its demand is elastic and highly sensitive to price fluctuations. In contrast, native chicken shows an R² value of 0.698 and an insignificant price effect on demand (0.164 > 0.05), suggesting inelastic demand that remains relatively stable despite price changes. These findings reveal that consumers adjust their broiler purchase quantities more quickly in response to price changes, whereas native chicken consumption is more strongly influenced by taste preferences and habitual factors. The study concludes that there is a clear difference in price sensitivity between the two types of chicken. The implications of this research include the need for government price stabilization policies for broiler chicken to maintain household affordability, as well as quality improvement and marketing strategies for native chicken producers to strengthen competitiveness amid changing consumer demand.

In recent years, there have been more and more cases of misuse of social media accounts, especially Instagram, through hacking carried out by individuals for illegal purposes. These hacks often involve using the victim's account for fraudulent actions, such as requesting money via the direct messaging feature to the account's followers. This problem raises a number of legal questions, including how the law regulates hacking and fraud on social media platforms such as Instagram, as well as the types of criminal sanctions that can be imposed on perpetrators. This research uses a normative legal approach to analyze existing regulations, especially the Information and Electronic Transactions Law (UU ITE). Based on the ITE Law, hacking is defined as an illegal activity to access, take or transfer electronic system data without permission, which can be subject to criminal penalties in the form of imprisonment and/or fines. In addition, if hacking is followed by fraud, the perpetrator can be charged with additional articles related to fraud as regulated in the Criminal Code (KUHP). This research also highlights the important role of social media organizers in protecting users through developing security features such as data verification. It is hoped that the results of this research can contribute to strengthening legal protection for social media users in the digital era.

Cone is a type of biscuit in wafer qualification that is cone-shaped and used as an ice cream holder. Cone is usually made from wheat flour with the addition of other ingredients as supporting ingredients. Research on making ice cream cones is still rarely done, especially making ice cream cones using red sorghum flour and Eucheuma cottonii puree. This study aims to determine the chemical, physical, and organoleptic characteristics of ice cream cones that are high in fiber and protein, and preferred by consumers. The research used a two-factor factorial completely randomized design (CRD), namely the ratio of wheat flour: red sorghum flour ((90:10), (80:20), (70:30)) and the addition of Eucheuma cottonii seaweed puree/100ml water (5%, 10%, 15%). The results showed that the best treatment was found in the treatment of the ratio of wheat flour: red sorghum flour (80: 20) and the percentage of Eucheuma cottonii puree 10% with fiber content of 4.14% and protein content of 9.73% and organoleptic tests with the results of color 3.53 (neutral), taste 4.23 (like), aroma 3.83 (neutral-like), texture 3.63 (neutral-like), overall liking 4.20 (like). Red sorghum flour ice cream cone and seaweed puree (Eucheuma cottonii) can provide an alternative in increasing food products that are high in protein and fiber.

The rolling process is a material forming method that is greatly influenced by the roll rotation speed parameter. Inappropriate rotation variations can cause various defects such as waves, tears, thickness irregularities, and ovalization. This review aims to compare the effect of variations in the roll machine rotation speed on the quality of rolling results on various types of materials, including Al6061-O aluminum plate, rubber sheets, and hollow and pipe-shaped materials. The method used is a literature study by collecting and comparing data on roll speed, defects that appear, deformation results, and process efficiency from several relevant journals. The results of the analysis show that high rotation speeds increase productivity but also increase the risk of defects because the material does not have time to adapt to deformation. Conversely, low rotation speeds produce more stable shapes and minimize defects, but are less efficient for mass production. Each material has a different optimal rotation range, including 23–36 rpm for Al6061-O plate, 45–72 rpm for rubber sheet formation, 24.4 rpm for hollow and pipe rolling, and around 21 rpm for corrugated plate. Overall, this study confirms that rotational speed control is a critical factor in achieving a balance between deformation quality and machining efficiency.

This study aims to analyze the level of flood hazard in Baturaja Barat District, Ogan Komering Ulu Regency, by applying a spatial approach using Geographic Information Systems (GIS) through the overlay method. The analysis was carried out by integrating six main physical parameters, namely rainfall, land use, elevation, slope, river density, and soil type. Each parameter was assigned a score and weight according to its influence on flood potential and subsequently processed spatially to produce a flood hazard map. The results indicate that the Baturaja Barat District area is classified into three hazard levels: low (3.25%), moderate (70.64%), and high (25.84%). Areas with high hazard levels are predominantly characterized by densely populated settlements situated at low elevations and in close proximity to river networks, particularly in Tanjung Karang, Air Gading, Talang Jawa, Karang Agung, and surrounding villages. These findings highlight that land-use changes, topographic conditions, and the distribution of river networks play significant roles in increasing flood risk. The results of this study are expected to serve as a foundation for spatial planning, the strengthening of disaster mitigation policies, and the enhancement of community preparedness against flood hazards in the region.
