The purpose of this research is to examine how production costs factor into producer choices, particularly those pertaining to output volume, selling price estimation, and company growth strategies.  The research examined micro and small business players in Kediri Regency, East Java, employing a descriptive quantitative technique.  The findings demonstrate that the production cost structure, particularly the preponderance of variable costs, considerably affects the quantity of output and the margin for price adjustment.  It has additionally been demonstrated that saving money encourages manufacturers to take risks and grow their companies.  Moreover, management accounting-based cost tracking, waste reduction, and sourcing local raw materials are all cost management tactics that impact a company's strength and ability to compete.  Producers' long-term strategic decision-making is therefore influenced by effective production cost management, which in turn affects operational sustainability.

This research aims to determine whether the budget formulation of the Merah Putih Village Cooperative is in accordance with the norms and statutory regulations as stipulated in Law Number 25 of 1992 concerning Cooperatives, particularly in relation to Article 33 paragraph (4) of the 1945 Constitution, which emphasizes the principle of independence in the national economy. The results of this study focus on optimizing the establishment of the Merah Putih Village Cooperative to support the formation of national-scale cooperatives that function not only as savings and loan institutions driving the economy, but also address the challenges and risks that may arise from the establishment of the Merah Putih Cooperative. First, the issue of economic scale is crucial. Operations at the village level are often limited by available resources and market reach. Second, human resource capacity is a determining factor. The management of funds amounting to IDR 3–5 billion requires financial, business, operational, and marketing management skills that are not always present in every village. Experience with Village-Owned Enterprises (BUMDes) shows that one of their main challenges is finding local residents who are truly skilled managers. Third, elite capture or control by local elites can become a bottleneck. In villages with weak governance, influential figures may abuse their authority to control the cooperative for personal gain. Similar occurrences are often found in grant programs from Ministries/Agencies or the private sector, where key individuals dominate and exploit these resources for their own interests. Fourth, the risk of fraud.

This research aims to analyze the evolution and innovation of sharia savings products in Indonesia through a literature-based qualitative approach. The background of the research is based on the significant growth of the national sharia banking sector, driven by government regulations, technological advancements, and changes in customer preferences. This study uses a literature review method by analyzing various secondary sources such as scientific journals, regulations, and financial reports to identify the patterns of Islamic savings product development over time. The research results show that the transformation of sharia savings products is driven not only by religious aspects but also by the demand for service efficiency and financial inclusion. The merger of several Islamic banks into Bank Syariah Indonesia also accelerated the digitalization of Islamic savings services. Although there are challenges such as low Islamic financial literacy and limited infrastructure, development opportunities remain wide open through educational strategies and the integration of the halal ecosystem. Innovations such as the opening of online accounts and the diversification of goal-based products have successfully increased sharia financial inclusion, particularly among the younger generation. The implications of this research emphasize the importance of adaptive product development strategies, financial education, and cross-sector collaboration to strengthen the competitiveness and sustainability of sharia savings products in Indonesia.

The 2024 National Financial Literacy and Inclusion Survey shows that many Indonesians still do not understand financial fundamentals. This condition contributes to difficulty in managing personal finances. Therefore, financial education from an early age is needed to help people develop healthy financial habits. One effective medium for delivering financial education is a children’s savings book. However, most available savings books are less attractive and do not align with children’s preferences. This study aims to develop a children’s savings book design by integrating educational elements, such as a temporary money storage, based on users’ preferences. The Quality Function Deployment (QFD) approach was used to translate customer needs into product visualization. Data were collected through expert discussion, interviews, and questionnaires distributed using purposive sampling. The results show that the highest-priority feature for further development is the temporary money storage integrated into the book’s cover. This element was then incorporated into the children’s savings book design, while considering both functional and educational aspects.

This study aims to analyze the influence of digital transformation and lifestyle on saving decisions, with user satisfaction as a mediating variable among users of the KB Star application in Jember Regency. Digital transformation enables financial institutions to offer efficient, fast, and integrated services, while lifestyle reflects customer preferences and behaviors that also shape financial decisions.

This study provides implications for the development of digital services oriented toward customer satisfaction and lifestyle needs as a strategy to enhance loyalty and financial decision-making in the digital era.

The sacraments of baptism and the Lord’s Supper are the two main sacraments in the Christian tradition, both carrying profound theological and spiritual significance. A sacrament contains two essential elements: an outward sign (such as water, bread, and wine) and a spiritual reality (namely, the grace of God given through the sign). A sacrament is not merely a symbol, but a means of communion with Christ that strengthens faith and bears witness to God’s grace. In Christian theology, a sacrament is broadly defined as a rite or religious ceremony performed to symbolize or help bring about a transformation in the lives of those who participate in it. The Sacrament of the Lord’s Supper is one of the key sacraments in the Christian tradition, symbolizing the fellowship of believers with Christ through the shared consumption of bread and wine. Its meaning is profound, as it is not only a remembrance of Jesus Christ’s sacrifice on the cross, but also an expression of faith and a deep reflection on the saving love of God. The Lord’s Supper also contains an eschatological meaning, pointing believers toward the future. In each celebration of the Lord’s Supper, the people of Christ anticipate the heavenly banquet at the end of the age.  

This study aims to examine the existence of the Church in the context of salvation history from the perspective of systematic theology, focusing on the role and vocation of the ecclesia as the community of God's people. The background of this study departs from the belief that the Church is not just a religious institution, but has an existential and historical basis in God's saving work. The Church acts as an extension of Christ's mission which is continued in the power of the Holy Spirit. In this research, the author uses a qualitative method with a literature study approach. The data sources consist of the Holy Bible, theological books related to the title, as well as relevant theological journal articles. This research was conducted to understand the relationship between the Church's identity and its participation in salvation history, both dogmatically and functionally. The results show that the Church is called to be an active witness in the work of salvation, by carrying out prophetic, liturgical, and social functions. As an ecclesia, the Church is not just a collection of individual believers, but a community that lives in relationship with Christ as the Head. The discussion emphasizes that the Church has a mandate to live in unity, holiness, catholicity, and apostolate, all of which are rooted in God's grace. In conclusion, the existence of the Church in salvation history is eschatological and missionary. The Church is called to be a sign and means of salvation, and to take part in the salvation of the world.

The training was conducted in one day with a participatory-educational approach and socialization. This method includes providing materials, group discussions, simulations, and reflections from each individual. The activities showed high active participation from participants and were actively involved in the discussions that were carried out. This socialization provides evidence that an experience-based approach can effectively increase understanding and awareness of the importance of financial management that they are facing.

Public finance is a key element in state governance, especially in the collection and allocation of funds for public services and government. In the Islamic tradition, the concept of public finance has developed since the time of the Prophet Muhammad SAW with sharia principles such as justice, transparency, and accountability to achieve prosperity (falah) in the world and the hereafter. In the modern era, Islamic public finance faces new challenges and opportunities, especially through digitalization and economic globalization. Technologies such as blockchain and big data open up opportunities to increase the effectiveness and openness of Islamic public financial management. Innovations in sharia financial instruments such as zakat, waqf, and sukuk further strengthen the contribution of Islamic public finance to social and economic development. However, challenges such as low public understanding of sharia finance, gaps in access to technology, and the need for supporting regulations and infrastructure are still obstacles. Issues of fiscal sustainability, debt management, and the development of adaptive sharia instruments are also important concerns in the dynamics of the global economy.

Energy efficiency in air conditioning systems is a critical factor in reducing energy consumption and environmental impact. This study aims to analyze the energy performance of an air conditioning system using the thermodynamic cycle method. The analysis focuses on the refrigeration cycle, particularly the vapor compression cycle commonly used in residential and commercial systems. Key parameters such as coefficient of performance (COP), refrigerant flow rate, and enthalpy at each cycle point were examined to determine overall efficiency. Data were collected through simulations and experimental measurements under standard operating conditions. The results show that optimizing system components, especially the compressor and expansion valve, can significantly improve energy efficiency. The COP increased by 12% when a high-efficiency compressor was utilized. In addition, the selection of eco-friendly refrigerants contributed to better thermal performance and reduced environmental risks. This research highlights the importance of thermodynamic analysis in designing and improving air conditioning systems for sustainable energy usage. Future studies are recommended to incorporate real-time monitoring and adaptive control systems to further enhance system performance and energy savings.
