This research was carried out for approximately 1 month from 17 January – 05 March 2022. In situ measurements included temperature (Suhu), acidity (pH), and dissolve oxygen (DO). Directly in the Lab. Aquaculture Biotechnology Fakulty of Agriculture University of Muhammadiyah Sukabumi. the test included testing the ex situ water quality at the IPB University Laboratory. Testing ammonia and alkalinity. The results of the above objectives show a comparison of the growth of water quality in the vertiqua system (Vertical Aquaculture), to determine the effectiveness of the vertiqua system in goldfish cultivation on growth, feeding effeciency, and water quality.
 

Asnan Ridoanrisna. Efficiency Of Pakcoy Plants (Brassica Rapa) In Maintaining Water Quality To Support The Survival Rate Of Tilapia. Under Guidance By Robin And Novita Mz. Tilapia is a freshwater fish commodity with high economic value. According to data from the Central Bureau of Statistics (BPS), tilapia exports reached 12.29 thousand tons with a value of USD 78.44 million. Tilapia farming faces the risk of mortality which can lead to economic losses, one of which is caused by organic pollution. To address this issue, this research employs phytoremediation methods with varying plant densities to improve water quality and tilapia survival. The study was conducted with four treatments: A75 (plant density 75% of the aquarium surface area), A50 (50%), A25 (25%), and A0 (no plants), using an aquarium size of 60 x 30 x 50 cm³. Each treatment received chicken manure at 1.8 grams per aquarium and 40 tilapia fish per aquarium. Observations were made over 15 days in March 2023, measuring physical and chemical water parameters including DO, pH, TDS, temperature, and ammonia, as well as calculating the survival rate of tilapia. Using a Completely Randomized Design (CRD), the study found that treatment A75 achieved the highest survival rate at 62.5%. This result indicates that higher plant density in the phytoremediation method is more effective in maintaining water quality and supporting tilapia survival.

This study aims to determine the direct and indirect effect of personal capability, sophistication and utilization of technology on accountant performance with the effectiveness of accounting information systems as an intervening variable in riau islands shipping COMPANIES. The population in this study were all accountants owned by shipping companies under the auspices of the Indonesian National Shipowners' Association Riau Islands, namely 31 companies and each company had at least 2 finance department people. So that the population in this study were 103 respondents. To get a sample that describes the population, this research uses a saturated sample method, where the entire population is sampled, namely 103 accountants. The results of this study personal capability has a positive and significant effect on the accounting information system. Technological sophistication has a positive and significant effect on the accounting information system. Utilization of technology has a positive and significant effect on the accounting information system. Personal capability has a positive and significant effect on accountant performance. Technological sophistication has a positive and significant effect on accountant performance. Utilization of technology has a positive and significant effect on accountant performance. Accounting information system has a positive and significant effect on accountant performance. Personal capability indirectly has a significant effect on accountant performance through the accounting information system. In other words, personal capability significantly mediates the relationship between personal capability and accountant performance. Personal capability indirectly has a significant effect on accountant performance through accounting information system. In other words, technological sophistication significantly mediates the relationship between technological sophistication and accountant performance. Indirect utilization of technology has a significant effect on accountant performance through accounting information system. In other words, technology utilization significantly mediates the relationship between technology utilization and accountant performance.

This study examines the multifaceted impact of financial inclusion on industrial societies, focusing on its role in economic growth, social equity, digital transformation, and industrial development. Using a mixed-method approach combining systematic literature review and case studies from five industrial countries (Germany, South Korea, the United States, China, and Brazil), we analyze the mechanisms through which financial inclusion influences societal outcomes. Our findings reveal that financial inclusion significantly contributes to economic growth, with a 10% increase in inclusion indicators associated with a 0.2-0.7% rise in GDP growth rates. Moreover, we identify synergistic effects between financial inclusion and digital transformation, notably in mobile banking adoption. The study also highlights persistent challenges, including urban-rural divides and gender disparities in financial access. Cross-cutting themes emerge, emphasizing the importance of integrated policy approaches, regulatory innovation, and public-private partnerships in advancing financial inclusion. These insights offer valuable guidance for policymakers and financial institutions in designing effective strategies to leverage financial inclusion for sustainable and equitable economic development in industrial contexts.

The research conducted examined the influence of independent variables—targeting (X1) and relationship marketing (X2)—on the dependent variable, purchase decision (Y). The findings revealed that both targeting and relationship marketing individually have a positive and significant impact on customer purchase decisions at CV. Putramas Pratama Medan. Additionally, when considered together, targeting and relationship marketing significantly influence customer purchase decisions at the company. Based on these results, it is recommended that CV. Putramas Pratama should expand its target market to increase consumer responsiveness to the company's product offerings. Furthermore, the company should focus on building consumer trust by paying close attention to customer needs and feedback. This dual approach of broadening the target market and enhancing relationship marketing is expected to improve customer purchase decisions significantly.
