Abstract

Along with advances in technology, watering plants manually is considered less efficient because it requires the owner's time and effort. The purpose of this research is to design a prototype of an automatic plant watering device using the DHT11 sensor. This study uses a field experiment method, where the design is made according to the conditions in the field. By utilizing the Arduino IDE software using the programming language and ESP 32 as the main control system that will manage all input and outputcomponents. The DHT11 sensor will detect the temperature and humidity of the air around the plants, the output will be displayed on the I2C 16x2 LCD screen so that users can see the air temperature values in real time. In addition, the output from the DHT11 sensor will also send an on/off command to the relay. This command is used to control the flame of the water pump. The results obtained from this study arethat the relay will turn on automatically when the DHT11 sensor detects an air temperature of more than 30 ℃ and at that time the pump will automatically circulate water. When the DHT11 sensor detects an air temperature of ≤ 30℃ the relay will automatically turn off and the water pump will not turn on so the water will stop flowing. Thus the resulting prototype can be used as an automatic sprinkler design with the DHT11 sensor as an air temperature detector.ABSTRAKSeiring dengan kemajuan  teknologi, penyiraman tanaman secara manual dinilai kurang efisien karena memerlukan waktu serta tenaga pemiliknya. Tujuan penelitian ini merancang prototipe alat penyiraman tanaman secara otomatis menggunakan sensor DHT11. Penelitian ini menggunakan metode eksperimen lapangan, dimana rancangan yang dibuat menyesuaikan dengan keadaan di lapangan. Dengan memanfaatkan oftware Arduino IDE menggunakan bahasa pemrograman C dan ESP 32 sebagai sistem kendali utama yang akan mengatur semua komponen input dan output. Sensor DHT11 akan mendeteksi temperatur dan kelembaban udara di sekitar tanaman, keluarannya akan ditampilkan pada layar LCD I2C 16x2 sehingga pengguna dapat melihat nilai temperatur udara secara realtime. Selain itu, keluaran dari sensor DHT11 juga akan mengirimkan perintah on/off pada relay. Perintah tersebut digunakan untuk mengendalikan nyala pompa air. Hasil yang didapatkan dari penelitian ini adalah relay akan menyala secara otomatis ketika sensor DHT11 mendeteksi temperatur udara lebih dari 30℃ dan pada saat itu secara otomatis juga pompa akan mengalirkan air. Ketika sensor DHT11 mendeteksi temperatur udara ≤ 30℃ relay akan mati secara otomatis dan pompa air tidak akan menyala sehingga air akan berhenti mengalir. Dengan demikian prototipe yang dihasilkan dapat dijadikan sebagai rancangan penyiram otomatis dengan sensor DHT11 sebagai detektor temperature udara.

Abstract

Smart Home is actually a technology-based home. Smart Home technology is increasingly being developed after the discovery of Internet Of Things (IoT) Technology, where home appliances such as lights, fans, televisions, and fences can be controlled remotely. The purpose of this research is to develop a smart home technology that has been made before, by using the Outseal PLC as a controller, the ESP 8266 module as a liaison to the Blynk application, then using a photocell sensor, and a PIR sensor. The way this tool works is when the photocell sensor detects a room that lacks light, the lights will turn on automatically, and turn off automatically when the room gets enough light, and the function of the PIR sensor is to turn on the fan automatically when it detects movement of people entering the room. However the lights and fans can be controlled manually and controlled remotely using the Blynk App. From the results of the tests that have been carried out, the blynk application designed to control the opening and closing of the gate can work well. The PIR sensor works up to a distance of 20 meters, while the lack of light in the room can be detected by the photocell sensor

Abstract

Calculating the total impedance between two points that are equivalent and connected to a current voltage source still revolves around the discussion using the Wye-Delta transformation, the theory of the Series-Parallel formula, the loop current method and the node or node voltage method. These calculations are still ineffective and take quite a long time for certain complex circuits, because the calculations can only be done manually. So we need a special solution to facilitate us in the calculation process. In this case it is necessary to do a new transformation approach called Transformation [C]. This [C] Transformation Matrix will connect the old and new equivalent circuits. This study uses the Borland C++ Builder program with four kinds of complex circuit conditions tested. From the test results it can be seen that the results of program calculations are the same as the results of manual calculations and are proven to be easier, more effective and efficient than manual calculations which are complicated and require a long and lengthy calculation process. This software is very helpful and can be applied to calculate the total impedance of an electrical circuit system, especially in certain cases of conditioned complicated circuits.

Abstract

Electric motors are a very vital need in an industry, household and other needs. Electric motors that are often used in an industry are types of induction motors, where the induction machine is an electric motor that is very easy in its maintenance system so that this motor has the highest rating in its use system. In this study, using a single-phase induction motor as a maggot dryer is useful for making the maggot storage period longer and of high selling value. This study aims to protect the single-phase induction motor in the maggot drying system against temperature increase due to prolonged grinding using the DS18B20 sensor. So that the single-phase induction motor is able to work when the motor is unstable at the time of overcurrent. With the installation of the DS18B20 sensor, the single-phase induction motor will stop automatically when the given temperature setting has exceeded the limit set on the sonoff.  With the protection system of this single-phase induction motor, it can maximize the performance of the electric motor in the maggot drying process and provide convenience in remote motor control and time setting on and off using the Internet of Things (IoT).

Abstract

The electrical quality, especially voltage fluctuations, is very important to remain stable in supplying voltage to consumers. PT. PLN (Persero) has a minimum voltage limit of -5% and a maximum of +10% which is regulated in the Minister of Energy and Mineral Resources no. 3 of 2007 in the transmission system. However, the 150 KV transmission system often experiences voltage drops caused by conductors that are too long and inappropriate loads, so that in maintaining good transmission quality, a reliable system is needed. One of them is GI Cerme which has a double busbar type, which separates the two Java-Bali transmission sub-systems and is connected to supplies from West Surabaya GI and Lamongan GI. Even so, the Lamongan-Cerme network with a length of 26.77KMS and transformer load causes a voltage drop, in the case that occurred in April 2023 at GI Cerme at peak load it experienced a voltage drop of up to 137 KV, so it is necessary to overcome the voltage drop problem the transmission system was repaired at GI Cerme. Through the digsilent application, it is possible to simulate better system planning at GI Cerme so that the voltage can be repaired according to standards.

Abstract

Makassar is the center of government and business center in the province of South Sulawesi. The people of Makassar has a very high dependence on the use of electrical energy to meet their daily needs, both at home and at offices. The use of electrical energy which is quite high will cause an increase in customer bills every month. Therefore, this problem needs to be reduced by utilizing alternative energy sources. PLTS on grid is one of the solutions to reduce dependence on electrical energy from PLN. This research was carried out using a load simulation method based on the level of solar radiation in Makassar City at an installed power of 4500 VA. By using PLTS on grid the customer has two sources of electrical energy, from solar power and PLN line. The main source of electrical energy during the day is from on grid solar power and at night is from PLN line. If the power from the on grid solar power the day is insufficient to serve the load needs, PLN will automatically responsible for the electric power of the load. The simulation results show that the use of on-grid PLTS saves PLN's electricity consumption by 34.78% to 89.53%. These results illustrate that the potential for using on grid solar panels in the city of Makassar is very large

Abstract

Controlling the speed of a DC motor in proportion to changes in temperature of a K-type thermocouple uses a Programmable Logic Controller and the Human Machine Interface  to enable monitoring of the temperature and speed of the Direct Current  motor from changes in the thermocouple sensor as input in the form of temperature data reduced to analog. to digital converter  in the form of digital data and controls the speed of the DC motor by adjusting the Pulse Width Modulation. DC motor speed control for temperature changes from a thermocouple sensor with a control system using a Programmable Logic Controller and displayed on the Human Machine Interface. In this test, only heating the sensor at a temperature of 30 oC to 100 oC and the speed of the DC motor where the temperature is greater, the PWM value makes the DC motor rotate faster. In controlling DC motors with PWM using a frequency of 10 Hz to get a PWM value of 0% - <54% the motor will rotate at low speed. PWM  54% - <84%, the motor will rotate at medium speed. PWM 84% - >90%, the motor will rotate at high speed
