Abstract

The application of grass chopper technology in the livestock sector plays an important role in increasing the efficiency of feed provision, particularly for goat farms. This study aims to analyze the effectiveness of the use of grass chopper machines in accelerating the availability of feed and its impact on the productivity of goat farms. The methods used included observation and direct interviews with farmers who applied this technology. The results of the study showed that the grass chopper machine was able to shorten feed preparation time by up to 50% so that farmers could provide sufficient and quality feed in a shorter time. The machine capacity is 200 kg/h, with an average chopped size of approximately 3-4 cm. Consistent chopping can increase feed digestibility, which contributes to increased body weight and livestock health.

Abstract

Grape cultivation has gained increasing attention due to its short growing period and the high market value of its sweet, refreshing fruits. However, achieving optimal growth requires precise environmental and nutrient management, which can be challenging under conventional farming practices. This research aims to develop an automatic watering system that integrates soil moisture and nutrient monitoring to optimize grape cultivation. The system utilizes Nitrogen Phosphorus Potassium (NPK) sensors, soil moisture sensors, and a camera for growth observation, all connected through the internet of things (IoT) for remote monitoring via Android devices. A fuzzy logic controller is implemented to regulate watering duration based on environmental conditions such as temperature and humidity. Experimental results show that the system effectively adjusts watering duration to approximately six seconds when the temperature is between 25–32 °C and humidity is around 60%. The DS18B20 temperature sensor achieved an average error rate of only 0.12%, while the humidity sensor demonstrated 0.2% error, indicating high accuracy levels of 99.8%. Despite minor limitations related to internet stability and sensor calibration, the system demonstrates strong potential for commercial-scale smart farming applications, promoting resource-efficient and data-driven grape cultivation.
