The use of nitrogen-fixing bacteria in agriculture is an effective way to improve soil fertility and overall crop productivity. Bacteria such as Rhizobium, Azotobacter, and Azospirillum are able to extract nitrogen from the soil and convert it into a form that can be absorbed by plants, which is essential for the formation of protein, DNA, and RNA in plants. By utilizing the capabilities of these bacteria, the use of synthetic chemical fertilizers can be varied, thereby reducing the detrimental dampening effects on water quality and the environment. In addition, nitrogen-fixing bacteria improve water use efficiency and contribute to the health of aquatic ecosystems. The use of these bacteria has the potential to improve the results of a more thorough analysis with less cost and less environmental impact.

This study aims to describe the importance of ethical and cultural leadership in education, especially in creating a conducive learning environment, which not only focuses on academic achievement, but also on the formation of students' moral character. One of the main challenges in the world of education today is the decline in polite behavior and moral ethics in the school environment, which results in rampant violations of social and religious norms. Ethical and cultural leadership is expected to provide solutions to this problem by instilling strong moral values and maintaining the sustainability of cultural values. This study uses a qualitative approach with a library research method to analyze the concept of ethical and cultural leadership. The results of the study show that ethical educational leaders must uphold the principles of justice, responsibility, and transparency in every action, while cultural leaders must be able to maintain and adapt cultural values to remain relevant to the times. These two types of leadership are expected to create a healthy organizational culture and build integrity in educational institutions, as well as motivate their followers to play an active role in achieving holistic educational goals. Education leaders are expected to be agents of change who are able to balance the preservation of cultural values and the application of innovation in education.

Finpay Link, developed by PT Finnet Indonesia, is a unique URL generated by the Finpay Payment Gateway system to facilitate payment transactions via email, SMS, or messaging apps like WhatsApp. Designed to simplify transactions for MSMEs, it aims to contribute significantly to the company’s revenue through increased business transactions. However, since its launch in 2019, Finpay Link has not met the expected revenue targets, prompting the need for new innovations based on the existing product. Given the high adoption of WhatsApp in Indonesia, with 90.9% of social media users active on the platform, this study explores the design and development of a WhatsApp-based application using the design thinking approach. Aimed at MSMEs, this application is intended to drive business transactions and revenue. This qualitative case study employs observation and in-depth interviews for data collection. The study results include the design of new features like payment processing and transaction history tracking. Prototype testing using the System Usability Score (SUS) yielded an 89.5 score, indicating high usability. Positive feedback from users confirmed the value of the payment and transaction tracking innovations. Despite time limitations, this research provides a foundation for future enhancements and can serve as a reference for applying design thinking in business app development.

The problem of household waste, which accounts for 50-70% of the total waste in Indonesia, mainly in the form of organic waste such as food and vegetable scraps, is a major challenge in environmental management. Composting is an effective method of managing organic waste by turning it into compost. However, organic waste management in Indonesia is still minimally practiced because it is considered to have no economic value. A 50 kg capacity composter machine equipped with a vertical mixer and using an electric motor can increase composting efficiency. This study aims to analyze the feasibility of composter machines and to analyze the effect of speed and mixing time on composter machines on the homogeneity of organic waste. The research method used is quantitative experimental with factorial experimental design (DOE) to analyze the effect of speed and stirring time on the composter machine on the homogeneity of organic waste. The stirring speed variations tested were 30, 45, and 60 RPM, with mixing times of 20, 30, and 40 minutes. The results showed that the single mixer composter machine proved to be feasible and reliable in producing homogeneous organic waste, with a high process capability value of 5.86. The use of mixing speed from 30 RPM to 60 RPM and mixing time from 20 minutes to 40 minutes significantly increased the homogeneity of organic waste, with the highest value of 97.54% at 60 RPM speed for 40 minutes.
 

Fish is one type of aquatic product widely used by the community because of its advantages as a food ingredient, including a source of important nutrients such as protein, vitamins, fat, and minerals. Fish is often found in cans. Canned packaging contains the heavy metals lead (Pb), cadmium (Cd), and zinc (Zn), which can be released into food due to the long storage period. This study aims to identify and analyze heavy metals Pb, Cd, and Zn levels in canned tuna with an expiration date of less than 1 year. Samples of canned tuna came from five different brands. Qualitative analysis used color reagents, while quantitative research used an atomic absorption spectrophotometer (AAS). The qualitative study results showed that three samples of tuna contained heavy metals. Samples B and C were positive for Pb metal, while samples A and B were positive for Zn metal. The concentration of Pb metal was measured in sample B at 117.9 mg/Kg and in sample C at -0.0147 mg/Kg. The concentration of Zn metal in sample A was -0.0048 mg/Kg, and in sample B, it was -0.147 mg/Kg.

Decision Support System (DSS) is a system used to assist decision makers in determining the best alternative based on certain criteria. Determining retirement eligibility for ASN (State Civil Apparatus) employees is one of the important aspects in human resource management, where this decision affects the future of employee careers, their welfare, and state budget management. This study proposes the development of a decision support system for determining retirement eligibility for ASN employees using the Multi-Attribute Decision Making (MADM) method. The MADM method is a decision-making technique that considers several criteria and alternatives to produce optimal decisions. In this study, the criteria used to determine retirement eligibility include retirement age, length of service, work performance, health, and other factors relevant to the applicable pension policy. The method used in this system includes several steps, namely identifying criteria, assigning weights to each criterion, and evaluating alternatives based on these criteria using calculation techniques such as AHP (Analytical Hierarchy Process) or TOPSIS (Technique for Order Preference by Similarity to Ideal Solution). The results of this evaluation will provide recommendations on whether an employee is eligible for retirement or can still continue his career. The developed system is expected to facilitate the decision-making process regarding ASN employee retirement by providing objective and transparent analysis, so that the decisions taken are more appropriate and in accordance with applicable policies. Thus, this system can improve efficiency and effectiveness in human resource management in government agencies.
