Fruit flies remain a persistent threat to horticultural production, especially in tropical regions where seasonal shifts can significantly affect their population dynamics. This study investigated the species composition, diversity, and environmental drivers of fruit fly populations infesting Capsicum annuum and Solanum lycopersicum over a one-year period in Batu City, Indonesia. Using weekly sampling across four seasonal phases—dry-to-rainy transition, rainy season, rainy-to-dry transition, and dry season—fruit fly specimens were collected, reared, and identified. Environmental variables, including temperature, humidity, rainfall, light intensity, and pesticide application frequency, were monitored and analyzed in relation to fruit fly abundance using Principal Component Analysis (PCA) and multiple linear regression. A total of four species were recorded: Bactrocera carambolae, Bactrocera dorsalis, Atherigona sp, and Silba sp, with the latter representing a new regional record for East Java. Population peaks occurred during the rainy season and its transitional periods, while significant declines were observed during the dry months. Regression models revealed that temperature and humidity supported population growth, whereas pesticide use had a consistently suppressive effect—particularly for B. dorsalis and Atherigona sp. However, the models explained only 20–50% of the variation, suggesting that additional ecological factors may be at play. These findings deepen our understanding of fruit fly ecology in tropical systems and highlight the importance of integrating climatic and agronomic data in pest management strategies. The discovery of Silba sp. further enriches current biogeographical knowledge and signals the need for adaptive, interdisciplinary approaches to sustainable pest control.

Company value is one of the main indicators used by investors to assess the performance and prospects of a company. This study aims to analyze the influence of liquidity, solvency, and profitability on the value of consumer goods sector companies listed on the Indonesia Stock Exchange (IDX) for the 2019-2023 period. The research sample consisted of 20 companies selected using the purposive sampling method. Data analysis was carried out by multiple linear regression using SPSS 27 software. The results show that liquidity has a negative and significant effect on company value, solvency has a positive and significant effect on company value, while profitability does not have a significant effect on company value. These results indicate that management must pay attention to efficiency in managing liquid assets, maintain a balance between debt and its own capital, and consider other factors other than profitability in increasing company value.

Renewable energy systems, particularly those incorporating solar and wind power, are prone to stability issues due to the intermittent and fluctuating nature of these energy sources. This paper investigates several nonlinear control techniques—namely, adaptive control, sliding mode control, and fuzzy logic control—that are designed to improve stability in renewable energy systems. Through simulations, we demonstrate how these methods can effectively reduce fluctuations and maintain stable energy output, offering a robust approach to enhancing the reliability of renewable energy systems.

Abstrak:
Currently, we live with various conveniences, especially when shopping. These conveniences produce many benefits, but there are also some negative impacts, one of which is consumptive behavior. Consumptive behavior is the action of someone who uses or buys something, either goods or services excessively. Usually prioritizing the urge of desire rather than need. This urge of desire is what in the perspective of Sufism psychology according to Frager is something that needs to be minimized, the reason researchers chose Frager's concept of Sufism psychology is because consumer behavior is closely related to nafs, and Frager is a Sufism psychology figure who is most detailed in describing the concept compared to other figures such as Al Ghazali. This study aims to see how consumer behavior is studied in the theory of Sufism psychology according to Robert Frager and how psychospiritualism is applied in minimizing consumptive behavior. The method used in this study is a descriptive qualitative method with a form of library research. According to Frager's study of Sufism psychology, consumptive behavior can be categorized into tyrannical nafs and lawwamah nafs, but consumptive behavior can be reduced when it is in the category of inspired nafs. Meanwhile, consumptive behavior will completely disappear if it is at the level of peaceful nafs, pleased nafs, approved nafs, and pure nafs. The psychospiritual applications that can be applied include: fasting, seclusion, serving brothers, and remembering death.

Abstrak:
This study focuses on how the portrayal of female power in one of Disney's films, Mulan. Film can provide a construct in socio-cultural reality. With this construction, the content of the film needs to be considered, because the content of the film can change the mindset of the audience who watches. Women are usually often complementary figures and do not have dominance than men. This is an interesting study because women can be constructed with the image above. Therefore, researchers dissect the portrayal of female power presented by Disney. Researchers use Ferdinand De Sausure's semiotic analysis method which focuses on signifiers and signified in interpreting women's power in Mulan. The supporting theory in this study is film as mass communication and women in the media. The results of the study showed three depictions of female strength from the film Mulan, namely women who are brave, women who resist and women who has a confident nature.
