Abstract

Indonesia, as the world's largest archipelagic country, benefits from its unique geographical conditions, making airplanes the most suitable mode of transportation. This is evident from the increasing number of airlines, a notable development in the aviation field, particularly in military aviation, is the advancement of drones or Unmanned Aerial Vehicles (UAVs). In recent years, there has been rapid technological progress in fixed-wing UAV technology. UAVs are unmanned aircraft that can be remotely controlled by pilots or capable of autonomous flight using aerodynamic principles to generate lift. Fixed-wing UAVs have wings with a fixed configuration. Unmanned aircraft offer several advantages over manned aircraft, including extended airborne endurance with efficient fuel consumption, categorized as Medium Altitude Endurance UAVs (MALE UAVs). These UAVs optimize the Lift-to-Drag ratio (CL/CD) to improve their performance. Currently, unmanned aircraft are being extensively developed for various purposes, such as exploration, reconnaissance, mining, military applications, competitions, and more.

Abstract

Static testing of the propeller is necessary to take into account the amount of thrust generated by the propeller before it is attached to the propulsion system. However, for small-scale static testing, especially on the Unmanned Aerial Vehicle (UAV) propulsion system, it is still difficult to find. So the purpose of this research is to design and manufacture a static test tool for propeller thrust combined with a DC brushless motor, especially in the Unmanned Aerial Vehicle (UAV) propulsion system. This test tool uses the Arduino Uno Atmega 328 as its microcontroller which is directly integrated with the load cell sensor which functions as the main measuring tool for the amount of thrust generated by the propeller rotation. In the load cell, there is a change in voltage in the strain gauge resulting in a change in resistance, then the results of the change will be read by the HX711 module. The HX711 module will convert the analog signal generated by the load cell into a digital signal, making it easier for Arduino to read data. Measurement results in data from Arduino will be displayed via the 16x2 LCD. This research proposes a simple propeller thrust gauge static test that can measure forces from 0 N to 49 N with an error rate of 0.479%.

Abstract

In the cattle fattening business, feed is the main factor determining cattle growth. Providing quality feed is a challenge for ruminant breeders, both large ruminants and small ruminants, especially during the dry season where availability is very limited. Therefore, breeders are required to create other alternatives for providing quality feed, with good shelf life, at lower costs. One application of simple technology that could be a solution is through feed fermentation. This research aims to analyze: the effect of fermented feed on cattle fattening performance. The material used was 15 cows, consisting of 8 imported/foreign crossbreed cattle and 7 local cattle. The location of this fattening process is carried out at the Ibnu Hikam Tani Farmer's Cage, Kulur Sindangkasih Village, Majalengka. The method used is Operational Research (RO). The results of the research showed that by using fermented feed, the increase in body weight (ADG) of foreign breed cattle was 0.5-0.7 kg per day, while the growth of local cattle was 0.5 kg per day. Meanwhile, the average daily feed cost is IDR 20,000-25,000 per day per head. Farmers' perceptions vary regarding the price of feed and feed ingredients. Even though this self-mixed fermented feed is still below SNI standards, it does not reduce the nutritional quality for the nutritional intake needed by ruminants. This research concluded that by using fermented feed, foreign-breed cattle absorb more nutrients than local cattle. So it is recommended to improve feed quality by adding or changing the feed formula currently used.
