Recently, the public has been shocked by the high number of bad debts among Millennials. The development of digital technology brings various conveniences, but also presents new threats to children and teenagers. The high percentage of online loan borrowers aged 19-34 years, as well as children who are caught in online gambling, is a major concern. Around 60 percent of online loan users (pinjol) have an easy target of young people aged 19-34 years, and even 80 thousand children under the age of 10 are caught in online gambling (judol). The problem is, the Millennial generation or those aged 19-34 years are the largest "contributors" to these bad debts. Various experts say that the Millennial generation is in debt because of the Fear of Missing Out (FOMO) phenomenon, aka following trends so as not to feel "left behind". Some other experts think that their financial literacy is low.

This essay looks at an investigation into the economies, A significant topic in the policy equation of many has been fiscal federalism, which reflects the degree of fiscal autonomy and responsibility granted to subnational government developing, transitional, and industrialized nations. Scholarly attention has been drawn to Nigeria's federalism because of its intricacy and vibrancy. This is due to the fact that it has created numerous issues that could jeopardize the Nigerian state's corporate existence and continuity. Therefore, the relationship between Nigeria's fiscal federalism and the oil-rich nation's lack of economic development is highlighted in this study. Our main contention is that Nigeria's fiscal federalism has not sparked the growth that the system's designers had hoped for. Therefore, this essay looked at Nigeria's fiscal federalism's development, composition, and practices. In order to do this, the study used secondary sources to collect data and combined descriptive and analytical methodologies. According to the report, Nigeria has not functioned as a a federal constitution, making it a true federation. Taxing authority and fiscal responsibility are still heavily concentrated. Numerous issues, such as the federal government's dominance in income sharing, the lengthy period of military interregnum rule, and an excessive reliance on Federation Account revenue, have hindered Nigeria's practice of fiscal federalism. This study investigated how fiscal federalism and the chosen distribution formula contribute to unhappiness and violent agitation. In order to do this, the study used secondary sources to collect data and combined descriptive and analytical methodologies. Therefore, the study came to the conclusion that in order to promote sound fiscal independence, the federal government should give state governments some of its taxing authority. and rivalry between states.

It is well known that the fiscal federalism pattern that the military imposed on the country disregards the source of money and productivity. This study assessed Nigeria's fiscal federalism. in an effort to pinpoint the trouble spots. The survey research approach was used. The Z-test was used to assess the data gathered from the questionnaire. The results showed that the government-appointed commissions' recommendations on fiscal federalism had little effect on the economy because of a number of issues, including the 1999 constitution's flaws and the numerous issues with fiscal federalism that have resulted in the duplication of government operations and the waste of public funds. Nonetheless, among other things, it is advised that public officials follow the Nigerian fiscal responsibility bill and due process in order to guarantee an effective and sound fiscal federalism in Nigeria. Furthermore, it is important to make sure that all levels of government follow the constitutional provisions on budgetary relations, accountability, and transparency. Establishing a National Fiscal Commission is also advised in order to improve intergovernmental cooperation and understanding in ways that encourage communication between actors in the federal, state, and municipal governments.

This study aims to examine the effect of varying the length of oil palm empty fruit bunch (EFB) fibers on the mechanical properties and macrostructure of Palmfiber Reinforced Concrete (PRC) as an alternative to Glassfiber Reinforced Concrete (GRC). EFB fibers were selected due to their abundance, eco-friendliness, and potential to enhance the mechanical properties of lightweight concrete. The methods employed include flexural testing and macrostructural observation using five fiber length variations (3 cm, 4 cm, 5 cm, 6 cm, and 7 cm). The results show that a fiber length of 5 cm produced the highest flexural stress of 11.78 kg/cm², while a length of 4 cm yielded the highest modulus of elasticity at 162.2 kg/cm². Macrostructural observations revealed good bonding between fibers and matrix in most specimens, although performance differences were observed due to fiber distribution and manual compaction processes. In conclusion, fiber length affects the mechanical performance of PRC, yet production process optimization is necessary to achieve more consistent results.

The cooling system on the Jupiter MX 135 CC motorcycle functions to maintain a stable engine temperature to prevent overheating. There are two main types of cooling systems on motorcycles: Air Cooling System and Liquid Cooling System. In the Air Cooling System, the working principle involves heat generated by the motorcycle engine being dissipated through cooling fins located around the engine block. Air that flows through the fan or moves as the motorcycle runs will carry away the heat. Meanwhile, in the Liquid Cooling System, the working principle involves coolant (usually a mixture of water and antifreeze) flowing through channels inside the engine to absorb heat. The coolant is then carried to the radiator, where the heat is transferred to the air with the help of a fan. Common problems that occur in the cooling system of the Jupiter MX 135 CC motorcycle can interfere with engine performance and risk causing serious damage if not addressed promptly. Some of the common issues include, Low coolant level, Radiator damage, Water pump failure, Malfunctioning thermostat (thermostat stuck), Leaking or broken radiator hose, Radiator fan malfunction, Dirty or contaminated coolant, Ineffective fan (for air-cooled engines), Overheating due to excessive load. The objectives of this study are to understand how the cooling system on the Jupiter MX 135 CC motorcycle works, to identify damages occurring in the cooling system, and to solve the issue of water pump leakage in the cooling system. The methods used in this research include observation, literature study, interviews, and action methods. The results of problem identification in the cooling system of the Jupiter MX 135 CC motorcycle show, The water jacket gasket is corroded ,The bearing on the water pump is damaged, The water pump impeller is worn out, The radiator pump seal has hardened, causing a squeaking sound around the water pump, Solutions to the problems in the cooling system components include replacing the damaged and worn parts (head gasket, bearing, seal, and impeller) and refilling with new coolant.

This study investigates the profound impact of the protracted humanitarian crisis in the conflict zone of Syam on the mental health of healthcare professionals, employing a systematic meta-analytical approach across 47 independent studies (N = 12,487) published between 2011 and 2023. The findings reveal an alarmingly high prevalence of burnout, reaching 78.3% (95% CI [75.2–81.4]), with emotional exhaustion recorded as the most dominant dimension (M = 3.89; SD = 0.76). Additionally, secondary trauma was identified in 65.7% of all respondents (95% CI [62.4–69.0]), with the primary symptoms manifesting as post-traumatic stress disorder (PTSD) at 44.2% and depression at 39.8%. Meta-regression analysis demonstrated that the duration of exposure to conflict (β = 0.42; p < 0.001) and the intensity of workload (β = 0.38; p < 0.001) served as significant predictors of burnout. Meanwhile, the lack of psychosocial support (OR = 2.34; 95% CI [1.89–2.79]) and critical resource scarcity (OR = 1.98; 95% CI [1.65–2.31]) were strongly correlated with the emergence of secondary trauma among healthcare professionals. Furthermore, diverging from the more individualistic frameworks employed in the studies of Bdaiwi et al. (2020) and Bou-Karroum et al. (2020), this research explores the intricate entanglement of organizational and situational determinants that concurrently shape the mental health landscape of medical personnel operating in the Syam conflict zone. Moreover, the study's original contribution lies in identifying resilience adaptation patterns observed in 34.2% of participants, revealing that endurance capacity was cultivated through collective coping strategies and close peer support. According to the researchers, this study offers a new lens for designing community-based psychological interventions that are both sustainable and contextually grounded for healthcare providers affected by the protracted armed conflict in Syam.

This study aims to analyze the legal aspects of public information disputes in the context of state administration, focusing on the Decision of the Jakarta State Administrative Court (PTUN) Number 410/G/KI/2024/PTUN.JKT. A public information dispute is a dispute between a public agency and an information applicant regarding the right to obtain and use public information based on laws and regulations. In the era of globalization and the development of information technology, access to public information is one of the important pillars in realizing transparent and accountable governance. In Indonesia, the right to public information is guaranteed by Law Number 14 of 2008 concerning Openness of Public Information (UU KIP). However, in practice, disputes often occur between public agencies and the public regarding the fulfillment of the right to information. The Decision of the Jakarta PTUN Number 410/G/KI/2024/PTUN.JKT is an important case study because it reflects the dynamics of law in resolving public information disputes at the state administration level. This study uses a normative legal approach with a case study method. Data were obtained from the analysis of PTUN Jakarta decisions and related legal documents. The results of the study show that public information disputes often occur due to unclear boundaries between information that can be accessed by the public and that which must be protected. The Jakarta PTUN decision emphasizes the importance of consistency in the application of the Consequence Test Sheet and emphasizes that information related to public services must be open to public access. This study contributes to understanding the legal complexity behind public information disputes and provides recommendations for improving the dispute resolution system in the future. In addition, this study also reminds us of the importance of a balance between public information transparency and personal data protection, especially in the context of state administration.

Sexual violence is an act that is degrading, humiliating, harassing, and/or attacking a person’s body or reproductive function, typically caused by an imbalance of power relations or gender discrimination, which results in psychological and physical suffering. Sexual violence against children is a social problem that requires special attention because this crime involves children in its commission. The Institute for Criminal Justice Reform (ICJR) also emphasizes that intercourse with a child constitutes a criminal offense, even if it is framed as consensual, in order to protect the child’s rights and future. Based on this issue, the author aims to examine efforts to combat sexual violence against children under the guise of sexual consent to find the most effective strategies to reduce this increasingly widespread crime. The research method used is a normative and empirical juridical approach. The data used includes both primary and secondary data. Data collection procedures involve literature study and field research. The data analysis was conducted using qualitative analysis. The results of the study show that efforts to combat sexual crimes include both penal and non-penal measures. Penal efforts involve the government enacting more specific regulations on sexual crimes involving adults and children under the pretense of sexual consent, as well as taking repressive measures as a last resort. Non-penal efforts conducted by relevant institutions include public outreach and education that provides information about such criminal behaviors. The suggestions in this study are: (1) To prevent sexual crimes committed under the guise of sexual consent, it is necessary to involve the community and a supportive environment that is aware of unlawful acts occurring around them, and to collectively protect family and community members from engaging in harmful behavior. (2) The government is expected to establish more specific policies regarding sexual crimes involving adults and children under the pretext of sexual consent.

This research presents a personalized, context-aware recommender system to suggest Places of Interest (POIs) using a hybrid approach combining Bayesian inference and collaborative filtering. The system explicitly addresses the cold-start problem that new users face and improves recommendation accuracy by considering contextual variables such as user mood, budget, companion, and location. The system collects real-time contextual inputs for new users with no historical data and applies Bayesian inference to generate relevant POI suggestions. As users begin to interact and provide ratings, the system progressively shifts to a collaborative filtering mechanism, leveraging cosine similarity to identify similar users within comparable contexts. The recommender system focuses on three categories of POIs: restaurants, hotels, and landmarks. These locations are retrieved through the Google Maps API, and only mapped locations are considered. The system was implemented on Android devices and evaluated through a user study involving 25 participants from diverse backgrounds, including software developers, IT students, and general users. Evaluation metrics such as normalized Discounted Cumulative Gain (nDCG) and classification accuracy were used to assess recommendation quality. Results demonstrate that the system performs better than traditional methods, with nDCG improvements reaching up to 83 percent. Users reported high satisfaction regarding the recommendations' accuracy, ease of use, and contextual relevance. While the system offers significant improvements, it also has certain limitations. Its dependency on Google Maps data may restrict its scope, and using only four contextual factors limits the system’s adaptability to more complex user preferences. Future enhancements could include additional dynamic contexts such as weather, POI popularity, and time-related trends, as well as integrating more advanced models to increase personalization and flexibility in real-world applications.
