This study aims to analyze the financial performance of the Jambi Provincial Government using the Value for Money approach, which covers the aspects of economy, efficiency, and effectiveness during the 2017–2024 period. The population of this study consists of all financial reports of the Jambi Provincial Government, while the sample is the Budget Realization Reports for the observed years, selected using a time series technique based on data availability. This research employs a quantitative approach with a descriptive research design. The data used include secondary data obtained from official budget realization reports and primary data collected through interviews conducted at the Jambi Provincial Finance and Asset Agency. Data collection techniques comprise documentation and interviews, and data analysis is carried out using economic, efficiency, and effectiveness ratios within the Value for Money framework. The results show that the financial performance of the Jambi Provincial Government during the study period is categorized as economical, as the expenditure realization ratio is below 100 percent, indicating budget savings. However, in terms of efficiency, the performance is still considered inefficient because the ratio exceeds 100 percent, which means expenditure realization is higher than revenue realization. Meanwhile, in terms of effectiveness, financial performance is classified as effective since revenue realization has met and even exceeded the predetermined targets. In conclusion, the Jambi Provincial Government has managed its budget economically and effectively, but improvements are still required to enhance efficiency in regional financial management.

This research aims to design and implement an Internet of Things (IoT)-based coffee bean drying system with a hybrid power source that combines solar panels and PLN electricity. The research and development (R&D) method used included system design, prototyping, and energy performance and drying process testing. The system utilizes a 50 Wp solar panel, a 12 V battery, an Automatic Transfer Switch (ATS), an ESP32 microcontroller, a DHT22 sensor, a load cell, and actuators such as a heater and a fan.Test results indicate that the system consumes 415,835 Wh of energy per day, with the solar panel contributing approximately 350 Wh per day, reducing battery load and extending operating time by up to two times compared to a system without solar panels. Furthermore, the system maintains a stable drying temperature within the range of 41–45°C and gradually reduces the mass of the coffee beans until they reach the standard dry condition.The novelty of this research lies in the integration of a hybrid system based on solar panels and PLN (State Electricity Company) that is automatically controlled using an Automatic Transfer Switch (ATS), and supported by real-time IoT-based monitoring and control. This approach improves energy efficiency, operational reliability, and drying process stability compared to previous research, which generally used a single energy source and lacked integrated monitoring systems.Thus, the developed system has proven effective in increasing energy efficiency, maintaining drying quality, and supporting the use of renewable energy in the agricultural sector

Gelegar Pilpres Oktavois, Budi Gunawan — Mon, 20 Apr 2026 00:00:00 +0000

This research aims to design and develop an ESP32 microcontroller-based coffee bean drying control system to enhance efficiency and quality compared to traditional sun-drying methods. Conventional methods suffer from several drawbacks, including weather dependency, long drying durations, and a lack of temperature and humidity control, which can potentially degrade the quality of the coffee beans. The study employs the Research and Development (R&D) method, covering the stages of design, construction, and system testing. The system is equipped with a DHT22 sensor to measure temperature and humidity, and a capacitive soil moisture sensor to detect the moisture content of the coffee beans. An on-off control method is implemented using heaters and fans as actuators, managed via relays. Sensor data is displayed on an LCD and can be monitored in real-time. The test results indicate that the drying system functions as planned. In a trial using 3 kg of coffee beans, the system successfully reduced the initial moisture content from 55% to 12% within 3.5 days. The temperature control system exhibited a slow but stable response; the heater activates when the temperature drops below 60°C and deactivates when it exceeds 60°C. Similarly, the humidity control system activates the exhaust fan when humidity exceeds 60% and turns it off when it falls below 55%. This humidity control showed a rapid initial response that decelerated toward the end, with the system exhibiting lower stability compared to the temperature control.
