Abstract

One of the main challenges in processing red palm oil (RPO) was maintaining the stability of active compounds during the drying process. Therefore, appropriate technology was needed to maintain the nutritional quality of red oil. This study aims to evaluate the performance of a laboratory-scale vacuum dryer specifically designed for drying red palm oil. Vacuum drying technology was chosen because it operates at low temperatures and low pressures, thereby minimizing thermal damage to sensitive compounds. Tests were conducted to determine the relationship between temperature changes RPO and the percentage of mass loss of the material against heating time. The heating time was varied to 30, 45, and 60 minutes. Based on the test results, heating time significantly affects the increase in temperature and the decrease in RPO mass. The rise in RPO temperature occurs most rapidly during the first 15 minutes; after that, the RPO temperature remains relatively stable. The results of the mass loss test showed a mass loss of 95.40% at 30 minutes, 94.20% at 45 minutes, and 94.00% at 60 minutes.

Abstract

Oil palm was a leading oil-producing commodity used for both consumer and industrial purposes, while the waste in the form of oil palm fronds has potential as animal feed or compost. Utilizing this waste requires a shredding process to process it into these products. This study aims to determine the effect of blade angle and shaft rotational speed on the chipping results of oil palm fronds in an oil palm chipping machine. The parameters observed include machine chipping capacity, yield, and the percentage of good-sized chips. The study was conducted with three blade angle variations 15°, 25°, and 45° and three shaft rotation speeds 1,200–1,350 rpm, 1,400–1,550 rpm, and 1,600–1,750 rpm. Based on the test results, the chopper shaft rotational speed had a highly significant effect on chipping capacity, while the blade angle had a highly significant effect on both chipping capacity and the percentage of good-sized shreds. The highest chipping capacity was 45,55 kg/h, the highest chipping yield was 98.60%, and the highest percentage of good chip size was 97.88%.

Efforts to overcome these problems done by developing a mechanical threshing process, including by designing and construction a mesh thresher cylinder type of pepper threshing. Test results show, this pepper thresher has a weakness, namely low threshing efficiency so that it needs to developed. Based on these conditions, research is needed that aims to develop, modify and done performance tests on the pepper thresher. The modification was made by making the contact angle between the thresher cylinder and the threshing net is 60o and resulted length of the threshing contact field of about 5.23 cm. The independent variable was the thresher cylinder rotational speed varied into 540, 471, 451 and 352 rpm. The dependent variables were capacity, threshing efficiency and percentage pepper of damage. The results of the analysis showed that the rotational speed of the threshing mechanism had a very significant effect on the capacity, threshing efficiency and the percentage pepper of damage. Increasing the speed of the thresher cylinder can increase the capacity and percentage of damaged pepper, but reduce threshing efficiency. The threshing efficiency increase of the pepper thresher before and after modification was from 35.8% to 95.93% on the approaching treatment.

Abstract

The main problem in agricultural water management was the imbalance in water availability caused by suboptimal irrigation systems. Efforts have been made to develop a water level monitoring system that integrates ultrasonic sensors, Internet of Things (IoT) technology, and solar power to monitor irrigation automatically and in real time, especially in locations without electricity. Therefore, this study aimed to design, construction, and test the accuracy and error rates of an Internet of Things (IoT)-based water level monitoring system. The system was designed using ultrasonic sensors, the Blynk platform, an ESP32 microcontroller, and a 50 WP solar panel as the power source. Field testing was conducted on an open water channel with a depth of approximately 1.22 m. Data were collected every 5 cm within a water level range of 5–75 cm. The sensor was operated at distances ranging from 2.27 to 2.97 m. Observations were made by comparing the ultrasonic sensor’s measurements with manual measurements used as reference points. The test results show that this system has an average accuracy of 95.85%, with an average absolute measurement error of 4.15% and a calculated RMSE of 1.1412 cm.

Abstract

Shredding machines play a crucial role in agricultural waste processing. A common issue encountered was shredding efficiency, particularly due to the poor quality of the shredding blades. Currently, the process of shaping and sharpening shredding blades was still carried out traditionally, resulting in inconsistent cutting angles. Poor-quality blades result in high energy consumption and low-quality shredded output. To address these issues, a study was conducted aimed at developing a machine capable of integrating the blade forming and sharpening processes into a single system. This research phase includes mechanical engineering, machine performance testing, and analysis of test data. The observed data collected include cutting torque and improvements in cutting performance. The test material used was potato tubers. Based on the engineering results, the machine measures 70 cm in length, 30 cm in width, and 70 cm in height, and was powered by a 2 HP electric motor, with the forming and sharpening blades operating at 1,400 rpm. Based on the test results, after the shredding blades were formed and sharpened, the cutting torque was reduced from 14.85 N·m to 7.36 N·m. Other observations showed that there was an average increase in cutting performance of 50.30% after the blade forming and sharpening process was performed.
