Abstract

Unmanned Aerial Vehicle is one type of drone that has developed rapidly. UAV has a lot of potential that can be explored, both for personal needs such as a toys to professional needs such as military aid. As electronics and computer science develop, in-depth research on quadcopters is carried out. One of the studies that continues being developed is control system. Quadcopters needs control system in order to maneuver according to the purpose. The control system in a quadcopter includes many things, such as attitude and altitude control systems. This research is a simulation of the Parrot Mambo altitude control system using linearized transfer function and PID (Proportional Integral Derivative) by simplifying the Parrot Mambo block model in order to apply the PID tuning results into the Parrot Mambo nonlinear system. According to the results of the simulation, the application of the transfer function and PID in 5 levels of height test reduced overshoot to 0%, increased rise time to 4.216 seconds, and increased settling time to 3,468 seconds. Testing with 5 different masses with transfer and PID functions, was able to reduce overshoot to 0%, increase in rise time by 4.001 seconds, and increase in settling time by 4.216 seconds. In testing the response of the original blocks and simplified blocks, the results were identical results and did not affect the basic function of the system itself. This can be seen in the difference from the overshoot response which is 0.01%, the settling time is 0.1 seconds, and the rise time is 0.005 seconds.

Abstract

A cluster computer is a type of parallel or distributed processing system that consists of a collection of stand-alone computers that are connected and work together as one integrated resource (Morrrison, 2003). Cluster computers can be implemented for specific purposes, and using parallel processing methods such as MPI4PY (Message Passing Interface for Python) MPI4PY is used to execute parallel programs into subtasks, then send them to the cluster nodes for processing. This research focuses on designing, implementing, and knowing the performance produced by computer clusters using raspberry pi 3. To find out the resulting performance, a scheme is tested using a master node without a slave, one slave master node, two slave master nodes, and a master node. three slaves. The monitoring process is carried out using ganglia to determine the size of cluster resource usage. The monitoring results show the highest memory usages of 818.8M in 109 iterations of testing the master node and 2 slave nodes. The highest loads/process was 14.1 in 109 iterations of testing using only the master node. The highest CPU usages were 32.7% in iteration 109 tests the master node and 2 slave nodes.

Abstract

Flooding is still a difficult problem to solve, especially in big cities, especially during the rainy season. At the peak of the rain with high rainfall, the river is difficult to fill the large water discharge. For development of river water flow that has more water discharge, sluice gates are used to build the discharge in the river flow. By using a doorstop that is connected wirelessly to minimize flooding, so that the air can be controlled with the communication system between the latches properly. The mechanism used is to send sensor data to Arduino mega2560 as a microcontroller with nRF2L01 as the sender, using fuzzy logic to determine the latch opening of the river floodgates, and Simple Additive Weighting to see rainfall and received by Arduino nano which has nrf24l01 as a receipients where the average error percentage is 0,12%. The results obtained for calculating the rain sensor module when tested are in accordance with the conditions and output. And for the water level there is a sensor difference of 0.1375%.

Abstract

Orange are very popular and consumed by most Indonesians. Oranges are the fruit with the second largest productivity in Indonesia. North Sumatra province is one of the areas with the highest number of citrus harvests. Buyers of oranges in North Sumatra generally taste oranges before buying because taste is the most important attribute according to consumer perceptions. After tasting the rsa citrus fruit and the taste is sweet, the buyer will immediately buy the orange juice. During the wrapping process, sometimes the seller will mix fruit with lower quality and unsweetened taste. So from these problems this research focuses on making a system that can classify the taste of citrus fruit. The classification process is carried out using the naive Bayes method. The classification process requires training data with three parameters, namely color, weight and diameter. Color data obtained with the TCS230 sensor, weight data using the load cell sensor and diameter data using the ultrasonic sensor. After the data is obtained, the classification process will be carried out. After the classification process is complete, the hasl will be displayed on the LCD. The naive Bayes classification was tested with 15 test data and produced an accuracy of 80%.

Abstract

Rice fields are one of the most important agricultural sectors for a country, because rice fields are the largest source of food for the Indonesian people. Like rice, rice is a relatively short-lived seasonal crop. Rice production itself is largely determined by plant genetics and environmental management of the land. In the process of rice farming, sufficient water and regular nitrogen fertilizers on the land are needed. Lack of understanding of most farmers in cultivating land is one of the problems in agriculture that can make crop yields less than optimal. Therefore, a monitoring system with WSN (Wireless Sensor Network) technology was created to help monitor water level and water pH, making it easier for farmers to find out the benchmark for water level and the pH value of water in their land. The system consists of 3 (three) slave nodes and 1 (one) master node which is in charge of sensing and sending data on water level and water pH. From the test results that have been done, the system can send data from the slave node to the master node using LoRa SX1276 communication. The device is capable of covering a large area with low power consumption with an RSSI signal at node 1 of -112.88 dB, node 2 of -102.76 dB, node 3 of -110.1 dB. The system is also equipped with the TDMA method, which is useful for scheduling data delivery that can reduce data collisions. The results of the sensing data will be displayed periodically on ThingSpeak.
