Abstract

This research aims to prepare natural coagulants from Angsana leaves (Pterocarpus indicus willd) for Palm Oil Mill Effluent (POME) treatment, especially reducing main variables such as TSS, COD, and pH. The amounts of 100 mesh Angsana powder (5, 10, 15, and 20 grams) were extracted using NaCl solvent with concentrations of 0.25 M and 0.5 M, respectively. The extract (200 mL) were added to 500 mL of POME and stirred (180 rpm) for 30 minutes. The concentrations of TSS, COD, and pH in POME were analyzed. Results showed that the coagulation-flocculation process using Angsana leaves powder was able to reduce COD by 55.79% at a coagulant dose of 5 g/L with 0.25 M NaCl solvent and TSS by 99.75% at a dose of 20 g/L with 0.25 M NaCl solvent. However, treatment using Angsana leaves extract was not able to reduce COD to the predetermined quality standard limits while the TSS value met the quality standard. Therefore, POME treatment still requires further processing.

Abstract

Watakham Studio, a music studio operating in Palangka Raya, currently manages rental data manually, which can lead to recording errors, service delays, and difficulties in data archiving. This research aims to design and develop a music studio rental information system using the Waterfall method. This method is chosen due to its systematic approach, consisting of the following phases: requirements analysis, system design, implementation, testing, and maintenance. The developed information system focuses on the digital management of rental schedules, customer data, and transaction reports. A case study was conducted directly at Watakham Studio to ensure the system meets the real needs of users. The implementation results show that the system can accelerate operational processes, reduce the risk of errors, and improve service efficiency. By applying the Waterfall method, the developed information system operates according to the initial design and has a positive impact on studio management.

Abstract

In Islamic economics, business and ethics are not two conflicting concepts, but rather complementary. Business in Islam is not only a worldly affair but also part of the investment of the afterlife. Therefore, every business activity must be in accordance with moral and ethical principles based on Islamic values. Business ethics in Islam have a major influence on consumer trust and loyalty, as well as the sustainability of the business itself. Imam Al-Ghazali's thoughts on Islamic business ethics emphasize the importance of the principles of justice, honesty, and trust in economic transactions. This study aims to analyze Al-Ghazali's thoughts on Islamic business ethics and their relevance in business transactions in the modern market, especially in Plaza Jember. In the context of modern business, the ethical principles taught by Al-Ghazali are still very relevant, including the prohibition of usury, the distribution of wealth through zakat, and transparency in trade. Although his thoughts originated in the 11th century, the concepts he put forward can still be adapted in the contemporary economic system. The results of this study indicate that Islamic business ethics play an important role in building a fair and sustainable trading system. In modern markets such as Plaza Jember, the application of Islamic business ethics can increase customer trust and create a healthy business environment. By understanding and implementing the concept of Islamic business ethics, business actors can achieve profits not only in the world but also in the hereafter.

Abstract

Ibn Khaldun's economic thinking and the concept of Pancasila Economics developed by Mubyarto have significant relevance in understanding an economic system based on moral and social values. Ibn Khaldun emphasized the importance of cooperation, justice, and the role of the state in creating social welfare, which is in line with the basic principles of Pancasila Economics which place the economy as a tool to achieve social justice. This study aims to analyze the harmony between Ibn Khaldun's economic thinking and the concept of Pancasila Economics using a qualitative-descriptive approach through literature studies. The results of the study show that these two thoughts have similarities in aspects of the role of the state in the economy, distribution of justice, and social welfare based on ethical values and togetherness. This study contributes to providing a historical and philosophical perspective on the development of an economic system that is more oriented towards people's welfare and the principles of social justice in Indonesia.
