Exchange rates are a crucial indicator in an open economy, playing a significant role in influencing international trade, investment flows, and overall macroeconomic stability. This study aims to analyze the impact of rupiah exchange rate fluctuations on Indonesia’s economic growth during the period 2014–2023. The research employs a descriptive qualitative approach using secondary data obtained from official publications of Statistics Indonesia and Bank Indonesia. The main variables analyzed include the rupiah exchange rate against the United States dollar and Indonesia’s economic growth. The findings indicate that exchange rate movements are closely related to economic growth dynamics, particularly through international trade mechanisms, production costs, and the stability of the real sector. Depreciation of the exchange rate tends to enhance export competitiveness, but it may also trigger inflation due to rising import prices. Conversely, appreciation can help control inflation but may weaken export competitiveness. Therefore, maintaining exchange rate stability is essential to support sustainable economic growth and strengthen national economic resilience.

This study aims to explain the implementation of the three-act structure in scriptwriting for the feature video entitled “Jejak Rasa: Akar dari Tanah Priangan.” The background of this research is based on the tendency of audiovisual representations of cassava that remain partial, focusing only on either traditional or modern aspects without integrating both into a cohesive narrative. This study employs a qualitative approach based on creative practice, where the author acts as a scriptwriter responsible for designing the narrative flow using the three-act structure: set up, confrontation, and resolution. The production process consists of three stages: pre-production, production, and post-production, involving literature research, field observation, interviews with key informants, and the development of visual and audio narratives. The findings indicate that the implementation of the three-act structure successfully creates a systematic narrative that integrates historical, cultural, and modern dimensions of cassava transformation. This structure also effectively builds a coherent dramatic flow and enhances audience emotional engagement. The implications of this study are expected to provide references for academics and practitioners in developing research-based audiovisual scriptwriting, particularly in the context of local culture and gastronomy.

separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.

This research is motivated by the fluctuation in income of areca nut farmers in Lagan Tengah Village, Geragai District, East Tanjung Jabung Regency, which has decreased in recent years. This condition is suspected to be caused by high production costs and unstable areca nut selling prices at the farm level. Therefore, this study aims to determine the effect of production costs and selling prices on areca nut farmer income in Lagan Tengah Village. This research used a quantitative approach with multiple linear regression analysis. The study population was all 1,105 areca nut farmers in Lagan Tengah Village, while the sample size was 92 people, selected using simple random sampling based on the Slovin formula with a 10% margin of error. Data were collected through questionnaires, interviews, observations, and documentation. Data analysis was performed using the classical assumption test, the t-test (partial), the F-test (simultaneous), and the coefficient of determination (R²) test. The results showed that production costs had a partial and significant negative effect on areca nut farmer income, while selling prices had a positive and significant effect on areca nut farmer income. Simultaneously, both variables—production costs and selling prices—have a significant impact on the income of areca nut farmers in Lagan Tengah Village. The coefficient of determination (R²) indicates that production costs and selling prices are able to explain variations in areca nut farmer income quite strongly. From these results, it can be concluded that improving production cost efficiency and stabilizing areca nut selling prices are important factors in increasing the income of areca nut farmers in Lagan Tengah Village. The local government and related institutions are expected to support farmers through subsidy policies, increased market access, and fostering farm management to optimize and sustain farmer income.

Sweet corn is a high-value horticultural crop with steadily increasing demand for both fresh consumption and use as a raw material in the food industry. This study aims to evaluate the effectiveness of NPK 16-16-16 fertilizer on the growth and yield of sweet corn. The research was conducted at Sindangbarang Experimental Field, Faculty of Agriculture, IPB University from July to October 2025. This experiment used a Randomized Complete Block Design (RCBD) with a single factor, namely the dose of fertilizer application. Treatments were using fertilizer dosages of 0, 50, 0,75, 1,00, and 1,50 NPK 16-16-16, with a control treatment for comparison. During the vegetative phase, sweet corn exhibited similar growth responses across all fertilization levels relative to the control. However, all fertilizer doses significantly improved stover weight, cob weight with and without husk, cob length, cob diameter, yield per plot, and overall productivity compared to the control. The application of NPK 16-16-16 fertilizer at the recommended (1.0) rate achieved the highest relative agronomic effectiveness (103.11%), corresponding to a 1.03-fold yield increase over the control and outperforming the comparison treatment. Application of NPK 16-16-16 at the 1.0 recommended dose is suggested as the most efficient fertilization strategy for sweet corn production, as it maximizes yield and productivity without unnecessary increases in fertilizer input.
