Abstract

Surabaya is an urban area with limited land for farming, because there are many buildings. Farming requires a largearea and fertile soil. With the development of agricultural technology today, there is a new method of planting calledHydroponics. There are several types of hydroponic systems, namely Aeroponics (fog system) and Nutrient FilmTechnique (NFT). In this article, the writer uses NFT technique. NFT is a system that has a farming concept bychanneling nutrients to plant roots in a film or thin so that plants get food nutrients, namely water and oxygen. Theadvantage of using this NFT system is that it makes it easier to control plant nutrients and plant growth is fasterbecause plant roots are free to absorb nutrients to the maximum. From the results of the research conducted, the pHsetpoint value was 6.0. From the results of the research conducted, set point pH values of 6.4 and 5.8. From the testresults, the Ziegler Nichols method of type 1 for a setpoint of 6.4 gets a value of L=3 and T=22.44 and a setpoint valueof 5.8 gets a value of L = 3 and T = 23.76. After that, the setpoint 6.4 got the value of Kp = 8.976 Ki = 1.496 Kd =13,464 and the setpoint of 5.8 got the value of Kp = 9.504 Ki = 1.584 Kd = 14,256. 1. The setpoint value of 6.4overshoot is 8.37% rise time 20 s, and settling time is 45 s. The setpoint value of 5.8 overshoot is 6.89% rise time 25s, and settling time is 55 s.

Abstract

The widespread theft of storage warehouses, especially in rural areas, rarely supported by communication technology. A system was created to improve the security of storage warehouses with LoRa transmissions capable of sending data remotely. When there is an open warehouse door, this system will send the data to the warehouse owner's house with LoRa transmission in the form of open door information to detect theft early. The LoRa transmission test results in the early morning hours resulted in a success rate of 99.61% at a distance of 1.40 Km and a success percentage of 99.06% at a distance of 2.15 Km. The entire system has been tested at a distance of 1.4 Km, and the early morning hours resulted in a percentage success of 95.15%. An error occurred due to packet loss. As evidenced by the further distance of the test, the percentage of success will be reduced. Besides that, cellular connections around the testing area also affect. Where in the afternoon, cellular network traffic is denser compared to the early morning hours. As evidenced by the results of testing in the afternoon, there was a decrease in the percentage success by 5%. Overall, the security system created and tested resulted in the conclusion that the security system in this study had shown promising results.

Abstract

Wireless Personal Area Networks have battery powered, low data rate, and low cost, that have been researched invarious fields, like Xbee Pro S2C. It can build mesh network, consist of Coordinator, Router and End Device. Xbeecan perform point to point and multipoint communication. We evaluate delay performance and data loss for bothcommunication at indoor environment, to get Xbee’s successful transmission rate. This transmission sent themanipulated data and data from sensor finger clip by End Device Node as Tranmitter to Coordinator Node asReceiver. This data is sent with different interval time, 8ms for manipulated data and 500 ms for data finger clipsensor. Definition of Delay is the difference of difference of time between first data sent and first data received.From manipulated data measurement the delay of point to point is 1,17 seconds, whereas multipoint gets 1,332seconds. For delay data finger clip measurement of multipoint is 1,34 seconds. While data loss occur in multipointcommunication, for data finger clip measurement get the loss 53,33 % and 46,67% in random quartile of data, andfor manipulated data get 3,56 % loss.
