This study aims to understand how learning about rainbows can improve elementary school students' understanding of basic science concepts, particularly regarding the refraction of light and the color spectrum. The concept of rainbows is an important part of Natural Science (IPA) lessons because it involves optical phenomena that can be directly observed and related to students' daily experiences. In this study, the method used is a literature study, namely by collecting, reviewing, and analyzing various relevant library sources, such as scientific articles, textbooks, and educational journals that discuss the topic of science learning and the rainbow phenomenon. The results of this study indicate that learning about rainbows can be done through various interactive and fun approaches, such as through practical experiments using prisms, water droplets, or other simple media that can demonstrate the process of refraction of white light into a color spectrum. In addition, the use of visual media such as images, animated videos, and digital simulations has also proven effective in helping students understand the process of rainbow formation more concretely. Creative activities such as drawing rainbows, making color models, or role-playing as light and water droplets can also increase active student participation and make learning more enjoyable. This study also emphasizes the importance of integrating rainbow learning into the elementary school science curriculum systematically and contextually. Rainbow materials not only introduce scientific concepts in a fun way, but also develop critical thinking, observation, and experimental skills in children. With the right approach, this learning can foster students' interest in science from an early age. Therefore, the results of this study are expected to contribute positively to the development of more effective, creative, and developmentally appropriate science learning methods for elementary school students.

Indonesia’s Islamic capital market has experienced remarkable growth in recent years, evidenced by the increasing number of investors and the rising market capitalization of Sharia-compliant stocks. This article aims to analyze the performance and management strategies of Sharia stock portfolios by reviewing academic literature published in Indonesia between 2019 and 2024. Utilizing a literature review methodology, the study compares the return and risk characteristics of Sharia stocks with those of conventional stocks. It also evaluates the applicability and effectiveness of classical portfolio theories—namely, the Markowitz Model and the Single Index Model—in managing Sharia-compliant investments. The findings reveal that Sharia stock portfolios often perform competitively and tend to exhibit greater resilience and stability during financial crises. This resilience is attributed in part to the rigorous stock screening mechanisms that comply with Islamic principles, excluding sectors and companies that do not meet Sharia criteria. Additionally, various macroeconomic factors such as inflation, interest rates, exchange rates, and global economic fluctuations are found to impact the performance of Islamic stock portfolios. The article highlights that while Sharia investments align with ethical and religious values, they also offer practical advantages in risk management and diversification. Furthermore, digital technology and fintech innovation are seen as essential tools to enhance transparency, accessibility, and investor engagement in the Islamic capital market. The study concludes that the development of Sharia-compliant stock investments in Indonesia holds promising potential, especially if accompanied by improved financial literacy, inclusive investor education, and stronger technological infrastructure. This paper offers valuable insights for policymakers, market regulators, and investors interested in promoting sustainable and faith-based financial practices within Indonesia’s rapidly evolving capital market ecosystem.

This study aims to analyze the influence of the lifestyle of credit relationship managers (RMs) and the potential for fraud on the occurrence of non-performing loans in the banking sector. Relationship managers are the spearheads of credit distribution, interacting directly with customers, so their behavior, lifestyle, and integrity have a significant impact on the quality of a bank's credit portfolio. This study uses a qualitative descriptive method with a systematic literature review approach, reviewing various recent studies related to bank employee lifestyles, factors driving fraud, and their correlation with non-performing loans. The results indicate that a consumptive lifestyle disproportionate to income can increase the risk of fraudulent behavior, such as manipulation of credit analysis or collusion with customers, which ultimately results in an increase in non-performing loans. Furthermore, weak internal control systems, pressure to achieve credit targets, and moral hazard exacerbate this risk. A lifestyle that prioritizes social symbols and self-image can also encourage employees to engage in deviant behavior to maintain this lifestyle. Several studies have shown that RMs trapped in a hedonistic lifestyle are more vulnerable to conflicts of interest and violations of professional ethics. Meanwhile, the potential for fraud in banking practices is also influenced by employees' weak personal financial literacy, as well as limited training in risk management and ongoing work ethics. In an organizational context, a work culture oriented toward achieving targets without regard for the quality of credit analysis has the potential to create a work climate that is permissive of irregularities. This study recommends strengthening a culture of integrity through the establishment of a firm code of ethics, technology-based supervision (such as an AI-based fraud detection system), and regular training on a healthy financial lifestyle and risk management for RMs.

This study aims to examine one of the disciplines of Islamic law, namely the pricing mechanism from the perspective of Imam Al-Ghazali, in order to create a healthy market environment free from monopolistic practices and manipulation, and aligned with Sharia principles. This research employs a descriptive qualitative approach using a literature study method by reviewing various relevant books, classical texts, articles, and academic journals related to Islamic economics and Imam Al-Ghazali’s thought. The findings indicate that the concept of fair pricing is not solely dependent on the interaction between supply and demand, but must also consider moral and social dimensions, such as justice, honesty, and public welfare. Imam Al-Ghazali strongly emphasized that economic transactions should uphold ethical standards and social responsibility to prevent exploitation and inequality. He argued that pricing must reflect not only market dynamics but also the broader ethical framework rooted in Islamic values. Furthermore, the study explores the concept of economic equilibrium in relation to pricing mechanisms, where prices should ideally balance individual interests with communal welfare. The research also discusses the correlation between economic balance and price-setting policies, including the views of other classical and contemporary Islamic scholars. It is found that state intervention is permissible in certain conditions—particularly when market mechanisms fail to ensure fairness—thus justifying government roles in market supervision and price stabilization. One of the key concepts in Islamic economics is the notion of a just price (al-thaman al-‘adl), as emphasized by Imam Al-Ghazali.. This study concludes that understanding pricing from Al-Ghazali’s perspective offers valuable insights for building ethical and socially responsible economic systems aligned with Islamic teachings.

Lobster is one of Indonesia's marine resources that has high economic value and is very important for the country's economy, but excessive lobster fishing and smuggling of lobster seeds have caused a decrease in the productivity of marine resources and significant state losses, so effective law enforcement efforts are needed to protect Indonesia's marine resources from these illegal acts. The problem in this study is how the law is enforced by the West Tanjung Jabung Police against the crime of smuggling lobster seeds (Study of Case Register Decision Number: 144 / Pid.Sus / 2023 / Pn Klt ), and what factors are the causes. The research method used is normative juridical, a type of legal research that focuses on the analysis and interpretation of legal norms that apply in a legal system. The study shows that the three defendants in the crime of smuggling lobster seeds were sentenced to 2 years in prison and a fine of IDR 5,000,000 based on Article 27 number 26 Article 92 of Law Number 6 of 2023 concerning Job Creation. The factors causing this crime include internal factors (economic and education) and external factors (politics, environment, and lack of security). Suggestions from the study are: Reviewing the lobster seed export policy. Improving coordination between law enforcement officers and community participation. Improving the capacity and competence of law enforcement personnel.  

Type 2 Diabetes Mellitus (DM) is a disease caused by impaired insulin function, impaired insulin secretion, or both, resulting in a hyperglycemic condition. Patients with type 2 DM generally exhibit characteristics such as a Random Blood Glucose level exceeding 200 mg/dL and an HbA1c  level exceeding 6.5%. The accuracy of medication administration to patients must also consider the rationality of antidiabetic therapy in order to influence the success rate of optimal therapy. This study aims to evaluate the rationality of patient appropriateness and indication appropriateness in outpatients with type 2 DM at Tabanan Regional Public Hospital (RSUD Tabanan). This study employed a semi-quantitative observational research design with a retrospective approach by reviewing patient medical records from the initiation of therapy. Sampling was conducted using purposive sampling, whereby samples had to meet predetermined inclusion criteria. The results indicated that the age group with the highest prevalence of DM patients at RSUD Tabanan was over 56 years old (74%), with a predominance of females (63%). The most common comorbidity among DM patients was hypertension alone (24.5%). Based on the findings, the percentage of patient appropriateness rationality among DM outpatients at RSUD Tabanan was 97.5%, while the percentage of indication appropriateness rationality in type 2 DM outpatients at RSUD Tabanan was 98.5%.

The review attempts to bridge basic biochemical research with clinical applications, and provides a window into the manner in which pathway-based interventions are influencing the future of precision therapeutics.

Debt-receivable problems are classic problems in economic activities that if not resolved properly can result in legal uncertainty and losses to the parties involved. One of the legal instruments provided in the Indonesian legal system to resolve these disputes is through the bankruptcy mechanism. This study aims to review the legal provisions regarding bankruptcy as regulated in Law Number 37 of 2004 and evaluate the effectiveness of its implementation as a solution to resolving debt-receivable problems. The method used in this study is the normative legal approach, by reviewing statutory provisions, legal doctrine, and court decisions. The results of the study indicate that although normatively the bankruptcy mechanism has a clear legal structure, its implementation in the field still faces obstacles in terms of process efficiency, protection of creditor and debtor rights, and supervision of curators. Therefore, policy updates and optimization of the function of judicial institutions are needed to increase public trust in this mechanism.

Literature research as a research conducted by reviewing various journals and related reference books. The results of the study indicate that the quality assurance system model according to Deming emphasizes the importance of customer satisfaction and continuous improvement through 14 famous points. Deming also stated that the majority of production failures are caused by managers, so improving the quality of managers is the key to improving overall quality. The PDCA ( Plan, Do, Check, Action ) management function developed by Deming is the basis for managing continuous quality improvement and is the basis for the development of Total Quality Management (TQM).

The issue arises from Article 15 paragraph (2) letter f of the Notary Position Law (UUJN), which grants notaries the authority to draw up deeds related to land affairs but fails to clearly define the scope of that authority. This creates conflict with Article 2 of Government Regulation No. 37 of 1998 in conjunction with Government Regulation No. 24 of 2016, which stipulates that PPATs have the authority to draw up authentic deeds regarding certain legal acts in land affairs. This study employs a normative juridical method by reviewing statutory regulations and legal literature to analyze the issue. The results show that this overlapping authority leads to legal uncertainty and potential conflict between professional functions. In practice, although notaries are normatively granted authority in land-related matters, their implementation remains limited, as deeds drawn up by notaries cannot serve as a legal basis for land registration unless the notary is also appointed as a PPAT. Therefore, a legal reform is necessary, either through a revision of the UUJN or the establishment of implementing regulations that clarify each official’s authority. By doing so, legal certainty can be achieved, and inter-professional disputes can be minimized.

This study examines the effectiveness of the Problem-Based Learning (PBL) model in improving elementary school students’ learning outcomes by reviewing 15 national journal articles published between 2018 and 2024. The results show that PBL significantly enhances students’ abilities in cognitive, affective, and psychomotor domains, with improvements ranging from 7.1% to 83.3%. PBL encourages students to think critically, participate more actively in learning, and develop problem-solving skills through real and relevant situations. However, its implementation still faces several challenges, such as limited teacher training, inadequate facilities, and difficulties in shifting from conventional methods to this new approach. Based on the analysis, three main factors determine the success of PBL: appropriate learning design, the teacher’s ability to guide the PBL process, and the availability of supporting learning resources. The most significant positive impacts are seen among fifth-grade students and in schools located in the Java region. In conclusion, PBL is highly effective when supported by proper teacher training and adaptation to field conditions. Therefore, further teacher development programs and additional research on the long-term effects of implementing this model are strongly recommended.

The geomorphological condition of Fakfak Regency is dominated by limestone. It makes ground water difficult to access. The clean water crisis in Fakfak Regency requires people to look for alternative sources of clean water such as rainwater. However, during the dry season, people will have great difficulty with clean water. Cloudfisher or fog catcher is a technique for collecting fog that have condensed into water. Cloudfisher's ability to catch fog or dew and produce water varies depending on the situation with an average of around 2 liters – 10 liters/m2/day. The ability of this technology to produce water depends on the net material used, the size of the net, the direction and model of the net, and the location of the net placement. In this research, the potential cloudfisher to produce water in Fakfak Regency will be examined, with the ultimate aim of seeing how effectively this technology is applied in Fakfak Regency in terms of the amount of water produced. The method used in this research is a field study by reviewing locations in Fakfak Regency with the altitude, fog conditions, temperature and humidity that are most suitable for the application of cloudfisher technology. The fog catcher was installed using a standard research model using 65% and 85% cover nets. Each fog catcher material was installed for 1 month and the amount of water captured by the tool was checked every morning at 06.30 am. The location of the fog catcher is based on several factors including altitude, air humidity, fog frequency, temperature and wind speed. The average water volume obtained in the 65% cover net was 59.6 ml while in the 85% cover net it was 26.24 ml. Factors that influence the amount of water obtained are net material, net cover, fishing area, equipment placement, and weather. The fog catcher (cloudfisher) in Fakfak Regency has the potential to be used but still requires further research regarding the design and materials used so that more water can be obtained and can be used by local communities as an alternative source of clean water

The implementation of ballast water management is a very important strategic step in preventing marine environmental pollution, because ship ballast water often becomes a route for the spread of invasive alien species that have the potential to disrupt the balance of the ecosistem, harm the maritime economic sector, and endanger human health. This study focuses on ballast water management practices on the MT Timur Laut Mas 2 ship, with the aim of assessing how the procedures are implemented in order to prevent the entry of alien species, reviewing the implementation of both international and national regulations, and evaluating the performance of the Ballast Water Management Sistem (BWMS) technology applied. This study uses a descriptive qualitative method based on a case study, with data collection through interviews with ship crews and company management, direct observation on board the ship, technical documentation, and a review of supporting literature. The results of the study show that the implementation of the IMO Ballast Water Management Convention (BWMC) regulations on ships has been realized through the preparation of a Ballast Water Management Plan, detailed recording in the Ballast Water Record Book, and the use of a BWMS that relies on filtration technology and ultraviolet radiation. However, the implementation still encounters obstacles in the form of limited crew understanding of system operation, variations in water quality along the shipping route that affect filtration effectiveness, and technical obstacles in equipment maintenance. Therefore, a combination of compliance with international regulations, improving crew competency through continuous training, and optimizing sistem operations are key factors in strengthening the effectiveness of ballast water management. These findings confirm that the application of modern technology in accordance with regulatory requirements can enhance marine ecosistem protection while ensuring the sustainability of the maritime industry, thus positively contributing to environmental sustainability and the stability.
