Abstract

The purpose of this study is to examine the affects of accounting conservatism, independent commissioners, and inventory intensity on tax avoidance with institutional ownership as a moderator. This study was conducted quantitatively with research subjects consisting of companies on the Indonesia Stock Exchange listed during 2020-2024 in the industrial sector. The population studied in this research was composed of 67 companies using purposive sampling, resulting in 29 companies and a whole sample of 91 data after outliers. The data used was secondary data obtained from annual reports and company financial reports. The analysis techniques applied were multiple regression analysis and moderated regression analysis using IBM SPSS Statistics version 26. The outcome from this study reveal that accounting conservatism and independent commissioners have a negative impact on tax avoidance; inventory intensity doesn’t have impact on tax avoidance; institutional ownership is capable of weakening the impact of accounting conservatism on tax avoidance; and institutional ownership couldn’t moderate the impact of independent commissioners and inventory intensity on tax avoidance. Future research is expected to use sectors other than industry and add independent variables or use different moderating variables to provide broader insights.

Abstract

This study examines the relationship between the financial ratios of total asset turnover (TATO), debt to equity ratio (DER), and operating profit margin (OPM) on the dynamics of corporate profit growth, with net profit margin (NPM) serving as a moderating variable. The study utilizes secondary data obtained from the financial statements of companies in the food and beverage sub-sector listed on the Indonesia Stock Exchange for the period 2020–2024. A total of 45 companies were selected as samples using a purposive sampling approach, resulting in 230 observation units. A moderation regression approach was employed to test the research hypotheses. The findings indicate that DER and OPM have a significant positive effect on profit growth, while TATO's positive impact is statistically insignificant. Furthermore, NPM strengthens the relationship between OPM and TATO with profit growth, but does not moderate the relationship between DER and profit growth. These findings suggest that capital structure, profit margin management, and operational efficiency are key factors in driving profit growth. Meanwhile, asset utilization effectiveness has yet to produce a direct significant impact in the food and beverage sub-sector.

Abstract

Rat infestation by Rattus argentiventer remains a serious problem in irrigated rice fields, causing significant yield losses and threatening sustainable rice production. Conventional control methods rely heavily on chemical rodenticides, which pose environmental risks and show declining long-term effectiveness. Ultrasonic deterrent technology has been proposed as an alternative; however, its effectiveness in open-field agricultural environments remains inconsistent and poorly understood. This study aims to analyze the behavioral and migration responses of rice field rats to different ultrasonic frequency ranges to clarify the mechanisms underlying ultrasonic deterrence. A field-based experimental design was applied using paired treatment and control plots, with ultrasonic frequencies ranging from 20 to 40 kHz. Rat activity and movement were monitored through camera traps and motion sensors, and spatial behavior was analyzed using activity reduction rates, migration distance, and path deviation indices. The results indicate a clear frequency-dependent response, with ultrasonic exposure at 30–35 kHz producing the strongest avoidance behavior and directional displacement. These findings suggest that ultrasonic deterrence primarily induces spatial displacement rather than population elimination and provide important implications for the development of adaptive ultrasonic–IoT systems to support smart and sustainable pest management in rice agriculture.

Abstract

Rat infestation remains a major constraint to rice production, causing significant yield losses and threatening food security in many rice-growing regions. Although ultrasonic deterrent systems have been promoted as an environmentally friendly alternative to chemical rodenticides, their effectiveness is often inconsistent due to static frequency emission and rapid behavioral habituation. This study proposes an adaptive scheduling model for ultrasonic frequencies based on real-time environmental data to enhance long-term deterrence effectiveness. The model integrates environmental sensing, stochastic frequency selection, and habituation-aware control within a context-aware scheduling framework. Environmental data were acquired using field-deployed sensors, while the adaptive algorithm dynamically adjusted ultrasonic frequency, emission duration, and interval. Field evaluations compared the proposed system with static ultrasonic control. Results demonstrate sustained spectral diversity, reduced habituation, and significant decreases in rat activity and crop damage, alongside improved energy efficiency. These findings highlight the potential of adaptive ultrasonic control as a scalable and sustainable solution for smart agriculture, supporting chemical-free pest management and precision rice farming.
