This study aims to analyze the correlation between the principle of equality before the law and the affirmative action policy, which is expressed in the form of a 30% quota for women's representation in the political field, as stipulated in Law Number 7 of 2017 concerning General Elections. The focus of the study is directed at the extent to which this quota policy is in line with the principle of equality before the law and reflects substantive justice in democratic practices in Indonesia. The research method used is normative research by examining laws and regulations, legal doctrine, and relevant literature. This approach is used to assess whether the quota policy for women's representation is in accordance with the constitutional principle of equality, while also considering the challenges of its implementation in a socio-political context that is still gender biased. The results of the study indicate that the 30% quota for women in legislative candidacy is a form of positive discrimination intended to correct structural and historical inequalities in women's political participation. This policy is expected to open wider spaces for participation so that women have equal opportunities to play a role in the legislative process and public policy making. However, this policy has also drawn criticism. Some believe that the quota emphasizes fulfilling numbers rather than the quality and capacity of the individuals nominated. Therefore, the quota must be accompanied by efforts to improve the quality of women's human resources, political education, and transparent, merit-based selection mechanisms. This way, women's representation will not only be formal but also substantial and contribute significantly to democratic development. In conclusion, the 30% quota policy remains necessary as an affirmative step toward de facto equality. However, strengthening capacity and supporting systems is crucial for its implementation to align with the principle of equality before the law and achieve substantive justice.

This study investigates the corrosion inhibition potential of a newly synthesized organic compound, (E)-4-hydroxy-3-(phenylamino)pent-3-en-2-one (LASA3), using computational chemistry approaches. Density Functional Theory (DFT) calculations were performed at the B3LYP/6-31G(d) level of theory with the Gaussian09 software package to evaluate several key quantum chemical parameters. These parameters include total energy, the energies of the highest occupied molecular orbital (EHOMO) and lowest unoccupied molecular orbital (ELUMO), the energy gap (ΔEgap), dipole moment, chemical hardness, softness (σ), and the number of electrons transferred (ΔN). The computational results reveal that LASA3 exhibits a higher EHOMO value and a smaller ΔEgap compared to its precursor molecules, referred to as S.M.1 and S.M.2. A higher EHOMO value suggests that LASA3 has a greater electron-donating ability, which enhances its interaction with the metal surface. Likewise, the reduced ΔEgap indicates greater chemical reactivity and a higher likelihood of forming stable coordination bonds with iron atoms on the carbon steel surface. Electrostatic potential (ESP) map analysis further supports these findings by highlighting the distribution of electron density within the LASA3 molecule. The ESP maps show significant electron-rich regions localized around nitrogen and oxygen atoms, which are potential active sites for adsorption onto the steel surface. This adsorption process plays a crucial role in blocking active corrosion sites and reducing the rate of metal degradation. In conclusion, the theoretical analysis confirms that LASA3 has superior electronic properties for corrosion inhibition compared to its starting materials, S.M.1 and S.M.2. Its ability to donate electrons, favorable dipole characteristics, and strategically located electron-rich sites make it a promising candidate for further experimental evaluation as an efficient corrosion inhibitor for carbon steel applications.

The Titanic drama contains many figurative expressions that reflect deep emotions, life values, and internal conflicts. These figures of speech are used to describe love, fear, sadness, and hope in a more vivid and memorable way. The emotional experiences of the characters, especially Jack and Rose, are shown not only through direct dialogues but also through creative figurative language. This study aims to examine the types of figures of speech found in Titanic, a drama film directed by James Cameron. Using a qualitative descriptive method, this study analyzes the film's dialogues based on the conceptual figurative theory proposed by Lakoff and Johnson. This study identified three main types of figures of speech: structural, ontological (including personification and metonymy), and orientational figures of speech. The results showed that structural figures of speech were the most dominant type, appearing in 45.9% of the total data, followed by ontological figures of speech at 29.7%, and orientational figures of speech at 24.3%. This finding proves that figures of speech are not only used to beautify language but also to express feelings and views on life in a deeper and more emotional way. The allusions in Titanic help the audience understand the characters' thoughts and experiences better.

Advances in digital technology in the financial sector have encouraged Micro, Small, and Medium Enterprises (MSMEs) to shift from cash payment systems to non-cash payments through QRIS (Quick Response Code Indonesian Standard) as an effort to increase efficiency and modernize transactions. This research is motivated by the low level of QRIS adoption among MSMEs in Junti Village, Jawilan District, Serang Regency, Banten, most of which still rely on cash-based transactions. The purpose of this research is to analyze the implementation of QRIS by MSMEs, identify the obstacles faced, and assess the impact of the system's implementation on daily business activities. Data were collected through field observations, interviews with MSME actors, and supporting documentation, and this research was conducted in Junti Village in July 2025. The results revealed that some MSMEs that have adopted QRIS experienced benefits in the form of ease in conducting transactions, increased efficiency, and a more professional business image. These findings also confirm that the use of QRIS contributes to the acceleration of digital transformation in the MSME sector, although not yet fully optimal. The main obstacles encountered were limited access and the quality of internet infrastructure, which is still uneven, making it difficult for some business actors to utilize QRIS optimally. Based on these results, the study recommends the importance of increasing the intensity of socialization and training on QRIS use, as well as the need for ongoing support from local governments and financial institutions so that MSMEs can adapt more quickly and comprehensively to changes in digital technology, so that MSME digital transformation can take place effectively, inclusively, and sustainably. This study recommends the need for increased socialization, training, and support from financial institutions and local governments to encourage sustainable digital transformation of MSMEs.

This study investigates the relationship between fiscal dependence, the effectiveness of locally generated revenue (PAD), and the degree of fiscal decentralization on the Human Development Index (HDI) in four regencies on Madura Island Bangkalan, Sampang, Pamekasan, and Sumenep which have consistently reported the lowest HDI scores in East Java Province. Utilizing panel data from 2011 to 2023, the findings indicate that all regencies remain highly fiscally dependent, with fiscal dependency ratios exceeding 89%. Central government transfers dominate local budget structures, significantly limiting local fiscal autonomy. While PAD effectiveness shows notable achievements such as Pamekasan’s 136.09% realization rate its contribution to total regional revenue remains relatively low. This is reflected in the modest degree of fiscal decentralization, which ranges between 8.56% and 10.72%. Such fiscal limitations hinder the ability of local governments to invest in strategic sectors that directly impact human development, including education, healthcare, and public services. The analysis also reveals that despite effective PAD realization, its nominal value is insufficient to drive substantial improvements in HDI, especially when not supported by strengthened fiscal capacity and local economic mobilization. These findings suggest that PAD effectiveness alone does not translate into better human development outcomes without broader fiscal empowerment. Therefore, a comprehensive fiscal decentralization strategy is required one that not only enhances revenue generation but also improves budgetary governance and optimizes local economic resources. Strengthening local fiscal autonomy is essential for ensuring targeted, efficient, and equitable investment in human development sectors, ultimately fostering sustainable regional development across Madura Island.

This study aims to analyze the influence of derivative skills and literacy in economic mathematics on investment decisions of students in the Management Study Program. The study was conducted using a quantitative approach using primary data collected through questionnaires distributed to students. The collected data were then analyzed using multiple regression tests to determine the extent to which the studied variables influence investment decisions. The results of the multiple regression test indicate that derivative skills and economic mathematics literacy simultaneously have a significant influence on students' investment decisions. The coefficient of determination (R²) value is 0.551, which means that 55.1% of the variability in investment decisions can be explained by these two independent variables, while the remaining 44.9% is explained by other factors not examined in this study. This figure indicates that students' ability to understand and use economic mathematics concepts, especially in terms of derivatives, as well as their financial literacy, play an important role in forming rational and informed investment decisions. The results of this study indicate that mastery of economic mathematics concepts, especially derivative skills, has a direct impact on students' ability to make better and more logical investment decisions. On the other hand, financial literacy also influences how students assess and manage investments, resulting in wiser decisions. Therefore, it is important for educational institutions to integrate mathematical economics and financial literacy into their curricula to help students make more rational investment decisions and reduce potential future financial risks. Furthermore, this study also suggests the need to improve students' understanding of basic concepts in mathematical economics and financial literacy. Management study programs can strengthen their curricula by providing more in-depth training in the applications of mathematical economics, such as the use of derivatives in investment analysis.

Community-based village development serves as a crucial strategy to reduce regional disparities and enhance village self-reliance. However, among the 36 villages in Bintan Regency, only two were categorized as Independent Villages in 2023, one of which is Toapaya Selatan Village. This study aims to examine how community participation contributes to the achievement of Independent Village status in Toapaya Selatan. The research applied a descriptive qualitative method, with data collected through observation, interviews, and documentation involving 15 informants. The findings reveal that community participation occurred actively across four key stages: decision-making, implementation, benefit-taking, and evaluation. In the decision-making process, residents were engaged through structured deliberations beginning at the neighborhood (RT) level and culminating in the village development planning meeting (Musrenbangdes). In the implementation stage, participation was reflected in both physical development projects and empowerment activities that fostered local capacity. The benefit-taking stage showed that residents equitably shared the outcomes of development through a system of regional rotation and principles of fairness. In the evaluation stage, the community was provided with both formal and informal spaces to voice aspirations and feedback, ensuring accountability and inclusiveness in governance. Despite the relatively high level of participation, several challenges persisted, including the dominance of representative systems, which limited direct involvement of broader community members, and the need for stronger capacity-building efforts. These findings suggest that while Toapaya Selatan Village has successfully demonstrated the potential of community-based participation in achieving independent status, sustaining and replicating this success in other villages requires continuous strengthening of community capacity, more inclusive participatory mechanisms, and institutional support. Strengthening these aspects will not only enhance the quality of participation but also ensure sustainable development outcomes that can be applied as a model for other villages.

Happiness is the ultimate goal of every human aspiration. To achieve it to the fullest, humans strive to utilize all their potential. However, in practice, conflicts often arise between personal interests and the interests of others. The desire to realize all dreams becomes problematic when carried out without regard for moral values, especially in a household life built through the sacred bond of marriage. Many married couples fail to create domestic happiness due to uncontrolled ambition. This ambition, when not balanced with ethics and morals, has the potential to cause domestic conflict that results in the neglect of children's education in the family. A current widespread phenomenon shows that married couples spend more time outside the home for work reasons. This opens up opportunities for promiscuity in public spaces and reduces attention to family. If this phenomenon continues, serious problems in the family will become increasingly apparent. The rights and obligations of husband and wife are neglected, affection for children is diminished, and ultimately children feel more comfortable seeking environments outside the home. This condition becomes the entry point for negative speculation from society about married couples who are considered negligent in their household obligations. This research is expected to provide a significant contribution to understanding how families should function optimally. By placing religion as a foundation and making ethics and morals the foundation of social interactions, families can return to their true nature as the birthplace of quality generations with character, ethics, and spiritual values.

This article analyzes the song "Sukatani" by Sukatani Band as a form of musical expression that represents Eastern nuances within a post-punk aesthetic framework. The research was conducted using a qualitative-descriptive approach through a music analysis method based on Jan LaRue's theory in Guidelines for Style Analysis (1970), which includes six main parameters: melody, harmony, rhythm, texture, form, and instrumentation. This analysis aims to reveal how the musical elements in the song can be read as a meeting between the post-punk idiom born in the West and the local socio-cultural context in Indonesia. The research findings show that "Sukatani" combines a minor pentatonic scale and repetitive structure as distinctive Eastern musical characteristics, while maintaining the monotonous and intense impression synonymous with post-punk aesthetics. From a lyrical perspective, the use of ngapak language not only strengthens local identity but also presents an authentic expression close to the daily lives of rural communities. The lyrics voice social criticism regarding class inequality, state repression, and respect for peasant labor as the foundation of collective life. Thus, music is not merely an aesthetic medium, but also a means of articulating cultural resistance against the dominance of central discourse and the hegemony of mainstream popular culture. Furthermore, analysis of texture and instrumentation reveals a combination of distorted guitars, repetitive bass patterns, and rigid drum beats, all of which create a tense yet meditative atmosphere.

Wireless Medical Sensor Networks (WMSNs) are a key component of modern Healthcare Internet of Things (IoT) systems, enabling continuous and real-time monitoring of patients’ physiological parameters. These networks support timely medical intervention, improve patient outcomes, and facilitate remote healthcare delivery. However, due to the open and resource-constrained nature of WMSNs, they are highly susceptible to various security threats, particularly during the authentication phase. Existing authentication protocols have been found vulnerable to a range of attacks, including impersonation, session key disclosure, and gateway database compromise, which can lead to severe privacy breaches and potentially life-threatening situations. To address these issues, this paper proposes a secure and lightweight three-factor authentication protocol tailored for WMSNs in healthcare IoT environments. The proposed protocol integrates Elliptic Curve Cryptography (ECC) for strong public key-based security with minimal computational overhead, fuzzy extractors to securely handle biometric information and ensure resistance against biometric template compromise, and session-based randomness to achieve forward secrecy and prevent replay or key-compromise impersonation attacks. Security analysis demonstrates that the proposed protocol successfully mitigates prominent threats such as impersonation attacks, man-in-the-middle attacks, session key leakage, and database compromise. In addition, the protocol ensures mutual authentication between the user, the gateway, and the sensor nodes, while maintaining data confidentiality and integrity. Performance evaluation indicates that the protocol offers significantly reduced computational cost and communication delay compared to existing schemes. Its low energy consumption and minimal storage requirements make it suitable for deployment in resource-constrained medical devices and large-scale IoT healthcare networks. The results highlight the protocol’s scalability, energy efficiency, and robustness, making it a practical and secure solution for safeguarding patient data and ensuring trustworthy communication in WMSNs-based healthcare IoT systems.

Feed is a key component in catfish (Pangasius hypophthalmus) cultivation because it directly affects the growth rate, health, and productivity of the fish. Among the various nutrients contained in feed, protein plays a crucial role, particularly in the formation and repair of fish body tissues. Adequate protein content supports optimal growth, while protein deficiency can reduce productivity. Therefore, analyzing protein levels in feed is essential to ensure its quality. This study aimed to analyze protein levels in catfish feed using the Kjeldahl method. The analysis was conducted at the Pekanbaru Center for Standardization and Industrial Services (BSPJI). The Kjeldahl method was chosen because it is known to have a high level of accuracy and reliability. The procedure involves three main stages: destruction, distillation, and titration. The working principle of this method is to convert organic nitrogen in the sample into ammonia, which is then captured and measured to determine nitrogen levels, which are then converted to protein levels. In this study, five feed samples with codes U-139 to U-142 were used. The test results showed that the protein content of the samples ranged from 20.44% to 23.09%. Furthermore, a Relative Percent Difference (RPD) value of 0.0013% was obtained, indicating a very high level of measurement precision. The analysis results were then compared with the fish feed quality standards based on SNI 2534:2006, and it was found that all samples met the minimum protein content requirements. Thus, this study confirms the effective and accurate use of the Kjeldahl method in analyzing protein content in catfish feed. These results also provide important information for farmers and feed producers in ensuring the quality of feed used to support catfish farming productivity.

This study aims to determine the effect of using educational gim-based learning media on students' math learning outcomes on the material of Linear Equation One Variable (PLSV). The background of this research is the low student learning outcomes in conventional math learning which is considered less interesting, especially in PLSV material which is abstract. This study used a quantitative approach with a quasi-experimental design and a nonequivalent control group design. The sample consisted of two classes, namely the experimental class (using educational gim media) and the control class (using conventional methods), which were taken from VII grade students of MTs Ra’iyatul Husnan, Wringin Bondowoso. The research instrument was in the form of pretest and posttest tests that had gone through validity and reliability tests. The pretest results showed that both classes had relatively balanced initial abilities. However, in the posttest, the learning outcomes of experimental class students showed a more significant increase than the control class. The data were analyzed using normality, homogeneity, and Mann-Whitney U Test hypothesis tests because the posttest data were not normally distributed. The analysis results showed a significance value of Asymp. Sig. (2-tailed) significance value of 0.000 <0.05, which means there is a significant effect of using educational gim media on student learning outcomes. This finding shows that interesting and interactive learning media such as educational gims can improve students' motivation, understanding and learning outcomes in mathematics. Therefore, the use of educational gims is recommended as an innovative alternative in learning mathematics, especially on material that is abstract and difficult for students to understand.

This study aims to describe students' critical thinking skills in solving social arithmetic problems based on the Polya stages and FRISCO indicators. The research subjects consisted of three students in grade VIII R-5 MTs Nurul Jadid who were purposively selected to represent the high, medium, and low ability categories out of a total of 21 students. The research method used was a descriptive qualitative approach with instruments in the form of two social arithmetic description questions and semi-structured interview guidelines. Data analysis was carried out by referring to the four stages of problem solving according to Polya (understanding the problem, planning the solution, executing the plan, and re-examination) as well as the six FRISCO critical thinking indicators (Focus, Reason, Inference, Situation, Clarity, Overview). The results of the study showed that students with high abilities were able to solve problems systematically through all stages of Polya and met almost all FRISCO indicators, especially in the aspects of Focus, Reason, and Clarity. Students with moderate ability show sufficient understanding but are inconsistent in planning and implementing solutions, and experience difficulties in the Reason, Situation, and Overview indicators. Students with low abilities experience obstacles from the early stages of understanding problems and do not show significant indicators of critical thinking. These findings indicate that the Polya stage and the FRISCO indicator can be used in a complementary manner to identify and analyze students' critical thinking skills in solving contextual math problems. The implication of this study is the need for a learning strategy that emphasizes strengthening the stages of problem solving and developing explicit critical thinking indicators in the mathematics learning process. This research also opens up opportunities for the development of more structured diagnostic instruments in measuring students' individual critical thinking skills.
