2024-12-24T00:36:09+00:00

Paddle aerator is an important tool in intensive shrimp farming. The purpose of this study is to determine the performance and electrical power consumption of paddle aerators based on the results of dynamic modelling analysis. This study uses causal ex-pose facto design concept with data analysis using dynamic modelling system. The results showed the salinity levels of pond 1 20-27 gr/L and pond 2 31-33 gr/L, pH pond 1 7.9-9.0 and pond 2 8.1-8.3, DO concentration pond 1 4.43-6.93 mg/L and pond 2 4.72-5.99 mg/L, temperature pond 1 27.15-31.400C with a brightness of 43 cm and pond 2 ranging from 27.50-29.850C with a brightness of 49 cm. From the calculation of the level of oxygen production paddle aerator power 1 HP produces oxygen average 2.12 mgO2 / hour (1.68-2.89 mgO2 / hour) with gas pressure 10.31-16.00 mmHg and paddle aerator power 2 HP produces oxygen average 3.20 mgO2 / hour (2.82-3.65 mgO2 / hour) with gas pressure 10.05-14.56 mmHg. From the accumulated results, the electrical load power required for pond 1 is about 6.83-10.38 kW and pond 2 is about 6.59-7.71 kW. The performance of 1 HP paddle aerator is more effective than 2 HP paddle aerator 4 pieces. The results of dynamic model analysis estimated the level of dissolved oxygen production by paddle aerators during one cultivation cycle ranged from 1-2.70 mgO2/hours and 1-2.75 mgO2/hours with a rotational speed of 0-30 rpm/s and power requirements of 8-10 kW. The conclusion from the results of this study is that the use of 1 HP paddle aerators in large quantities is proven to be more effective and based on the results of dynamic modelling system analysis, it is shown that the performance of DO production by paddle aerators will stagnate at week ten of the cultivation period, with increasing electrical power requirements.

The Role of Financial Literacy and Self-Control in Managing Students' Consumptive Behavior with PayLater Usage Decisions as a Mediating Variable

2024-12-24T01:00:13+00:00

This study investigates the influence of Financial Literacy on Consumptive Behavior among students, with PayLater Usage as an intervening variable and Self-Control as a moderating variable. The rapid adoption of digital credit services, such as PayLater, has reshaped consumption patterns, particularly among young users, by promoting convenience and flexible payment options. This research aims to understand how financial literacy and self-control interact to influence students’ consumption behavior through PayLater usage. Using Structural Equation Modeling (SEM) with a sample of 100 students from the Faculty of Economics and Business at Universitas Teknologi Sumbawa, the study finds that Financial Literacy has a positive influence on both PayLater Usage and Consumptive Behavior. Interestingly, while financial literacy is generally expected to mitigate consumptive tendencies, it indirectly contributes to impulsive spending by encouraging the use of PayLater. PayLater Usage is identified as an intervening variable that strengthens the relationship between Financial Literacy and Consumptive Behavior, highlighting the role of convenience and perceived purchasing power in promoting consumption. Moreover, Self-Control negatively moderates the relationship between PayLater Usage and Consumptive Behavior, indicating that students with high self-control are less likely to exhibit impulsive spending despite using PayLater.

Analysis of The Influence of Social Commerce Tiktok Shop on Purchase Intention

2025-01-21T16:06:05+00:00

The digital era has driven the development of social media platforms as a means of transaction known as social commerce. TikTok Shop is one of the platforms that is increasingly in demand by consumers for online shopping, so it is important to understand the factors that influence social commerce and purchase intention. This study aims to analyze the effect of accessibility and promotion on social commerce, as well as its impact on purchase intention on TikTok Shop users in Sukabumi Regency. With a quantitative approach, this study involved 140 respondents who had made at least three purchases. The data analysis technique used Structural Equation Modeling (SEM) with the AMOS program. The results of the study indicate that social commerce has a significant effect on accessibility (P Value = 0.000; CR = 4.443) and promotion (P Value = 0.034; CR = 2.116). In addition, purchase intention also has a significant effect on social commerce (P Value = 0.000; CR = 4.513) and accessibility (P Value = 0.049; CR = 1.972). However, purchase intention does not have a significant effect on promotion (P Value = 0.304; CR = 1.027). This study strengthens previous findings that show the importance of social commerce in increasing accessibility and promotion, as well as the relevance of purchase intention in influencing social commerce and accessibility.

Analysis of Determinants of Propensity to Independence Based on Behavioral Biases, Emotions, Culture, and Materialism Moderated by Religiosity, Financial Literacy and Job Security

2025-01-21T16:45:45+00:00

This study aims to analyze the determinants of Propensity to Indebtedness among civil servants (ASN) and employees/entrepreneurs in Indonesia. The main focus of the research includes the influence of financial behavior biases, emotions, culture, and materialism on the tendency to incur debt, as well as how financial literacy, job security, and religiosity moderate these relationships. A quantitative approach was used in this study, employing an ex post facto design supported by a survey questionnaire. Primary data were collected through an online questionnaire distributed via Google Forms, with 400 respondents selected through simple random sampling. The results show that financial behavior biases, such as overconfidence and aversion regret, have a positive and significant effect on Propensity to Indebtedness. Emotions and culture also have significant influences, where emotional impulsivity and consumption-driven cultural values affect the tendency to incur debt. Materialism was found to strongly influence decisions to incur debt to fulfill lifestyle needs. Additionally, the moderating effect of financial literacy strengthens the relationship between financial behavior biases and Propensity to Indebtedness, indicating that better financial understanding helps individuals make wiser decisions. Job security also strengthens this relationship by providing emotional and financial stability. On the other hand, religiosity weakens the influence of emotions and materialism on Propensity to Indebtedness, although practical approaches are still needed to strengthen these effects. This research contributes academically by expanding insights into financial behavior and debt management, and it provides practical implications for the development of effective financial education programs aimed at improving financial literacy among Indonesian society.
