Abstract

This paper discusses the design and implementation of ultraviolet light control in corn fodder. The problem with corn fodder is that temperature and humidity and inappropriate lighting can trigger the growth of mold. The ultraviolet light illumination control system method uses a fuzzy logic method to control ultraviolet light illumination. So it affects temperature and humidity, as well as growth of corn fodder. The results of the comparison of the Mamdani fuzzy control system using Matlab and Arduino applications to control corn fodder illumination obtained defuzification values (0.5, 2.5, 6.5). The implementation of the Mamdani fuzzy logic control system affects the light, temperature and humidity, as well as the height and weight of the corn fodder with a definition error of 0.5%. Lighting 5 hours/day on a full spectrum grow light (380nm-730nm) with a light intensity of 2053lux, for 14 days produces a temperature of 27˚C and humidity of 93%, fodder height reaches 28cm with a total weight of 124 grams. Meanwhile, the grow light spectrum (450nm-460nm) with a light intensity of 1462.5 lux produces a temperature of 28˚C and humidity of 85%, the height of the fodder reaches 26.5cm with a total weight of 120 grams. Optimum lighting results were obtained in 5 hours of light with a full spectrum grow light lamp with a light intensity of 2053lux, for 14 days resulting in a temperature of 27˚C and humidity of 93%, the height of the fodder reached 28cm with a total weight of 124 grams.

Abstract

This study aims to analyze the effect of investor sentiment, dividend yield, and trading volume on the stock price volatility of banking sector companies listed on the Indonesia Stock Exchange (IDX) during the 2021–2024 period. This research employs a quantitative approach using panel data regression on 10 banking companies, resulting in a total of 40 observations. The model selection results indicate that the Random Effect Model (REM) estimated using the Generalized Least Squares (GLS) approach is the most appropriate estimation method. The findings reveal that investor sentiment has a positive and significant effect on stock price volatility, indicating that psychological factors play a more dominant role in shaping stock price dynamics within the banking sector. In contrast, dividend yield and trading volume do not have a significant effect on stock price volatility. These results suggest that stock price volatility in the banking sector during the observed period is more strongly driven by investors perceptions and expectations. This study is expected to provide valuable insights for investors in understanding the dynamics of the Indonesian stock market.

Abstract

This study aims to determine and analyze the influence of operational efficiency, management quality, liabilities, and Sustainable Investment Banking on the profitability of banks implementing Environmental, Social, and Governance (ESG) principles in Indonesia. The application of sustainability principles in the banking sector is increasingly important with increasing attention to responsible financial activities. This study uses a quantitative approach with secondary data obtained from the annual reports and sustainability reports of four major banks listed on the Indonesia Stock Exchange: Bank Mandiri, Bank Rakyat Indonesia, Bank Central Asia, and Bank Negara Indonesia for the period 2010–2024. The analytical method used is panel panel unbalanced data regression to examine the relationship between the research variables. The results show that operational efficiency, management quality, liabilities, and Sustainable Investment Banking have a significant influence on bank profitability. These findings suggest that efficient operational management and the implementation of sustainable investment activities can support improved banking performance in the long term.
