Abstract

Water is one of the most important sources of life. One way to save water is by monitoring the flow of water consumed per month. The flow rate measurement is applied to every household that uses the PDAM, so that each house is installed a water meter, which is used to measure or record the volume of water that has been used for each household’s needs. The measurement of the volume of water contained in the water meter is used to determine the number of tariffs that must be paid by each household to the PDAM every month of use. In this research, a system is made that can monitor the quality and use of PDAM water. In this system, a turbidity sensor is used which will measure the level of water turbidity in NTU units. This NTU value will show the quality of PDAM water whether it is suitable for use in daily needs or not. The water flow sensor will be installed in the middle of the PDAM pipe, the water flow data measured on the sensor will be processed on the Arduino Uno module to be converted into data for the estimated cost of using PDAM water. Furthermore, all data will be displayed on the LCD, namely data on the level of water turbidity, data on the amount of water discharge and the estimated cost to be paid by the customer. All data will be sent to the blynk server via ESP32 Camera. The data stored on the server can be accessed using the blynk application on a smartphone. In addition, the data will also be stored on the SD Card as a data backup. The results of the turbidity sensor readings show a water turbidity value of 5 NTU. The error value of the water flow sensor readings is 1.6%, which means the accuracy rate is 98.4%. While the data from the reading of the PDAM water usage costing system has no errors so that the data accuracy reaches 100%.

Abstract

The increasing development of engines in human life to facilitate human work for 24 hours, cannot be denied that the Generator Set or better known as Genset is very important role in keeping the engine alive during the power outages. For this reason, it is necessary to monitor a Ganset fuel tank to make it easier to find out the changing conditions of the Ganset fuel, and the automatic runhours calculation system so that the maintenance of the ganset can be easily determined based on the calculation of the life span of the ganset. Tank monitoring system and automatic calculation of runhours ganset that is designed based on IoT, this system uses an ultrasonic sensor to find out the height of the fuel tank in captivity, the current sensor as a live ganset detector, Nodemcu Esp8266 functions as data receiver from the sensor and sends it to the web application that has been created. From the test results it can be seen that the percentage of errors in the ultrasonic sensor is 5.2%, and testing on the current sensor that detects the current in the load with an error in the manual calculation time with the time on the web display only ranges from 1-2 seconds. Keywords: Tank Generator sets, NodeMCU Esp8266, Ultrasonic Sensors, Current Sensors, Servo, Server, Web.

Abstract

AbstrakSpeech Recognition (pengenalan suara) merupakan proses untuk mengkonversikan sinyal akustik (suara) melalui microphone sebagai perintah untuk mengoperasikan komputer yang digunakan untuk mengenali suatu kata yang diucapkan oleh seseorang. Pada penelitian ini speech recognition (pengenalan suara) digunakan untuk mengontrol Home Device dengan menggunakan ekstrak ciri Mel-Frequency Cepstral Coefficients (MFCC) dan pemodelan Hidden Markov Models (HMM). Mel-Frequency Cepstral Coefficients (MFCC) merupakan teknik yang mengambil contoh suara sebagai input. Untuk dapat memproses suara yang masuk pada mikrofon, maka sinyal suara diambil cirinya. Setelah cirinya didapat maka akan dibentuk pola oleh pemodelan Hidden Markov Models (HMM). Tujuan digunakan metode MFCC dan HMM diharapkan dapat meningkatkan keakurasian waktu dalam mengontrol Home Device. Home device yang digunakan dalam pengujian yaitu lampu dan kipas angin. Untuk pengontrolan tersebut dilakukan secara offline. Berdasarkan pengujian didapat tingkat akurasi sebesar 95,5 % dari 200 percobaan dengan menggunakan 10 kata perintah. Untuk pengujian menggunakan 2 user. Untuk pengujian dengan keadaan sekitar ribut (noise) didapat tingkat akurasi sebesar 7% dari 100 percobaan.

Abstract

Tin plants have various health benefits and high economic value, but these plants need attention in order to develop properly, so an IoT-based fig plant monitoring and control system is created. The system can find out the temperature, soil moisture, soil pH, and fruit color through sensors installed and forwarded to the owner's smartphone for monitoring the plants through the Blynk application, and can water automatically when the soil starts to dry and notify when the fruit is ripe. The system is also equipped with backup energy from a 6watt solar cell which from the test results is able to run the system with a load of +/- 17 hours. Solar cells are used if there is a disturbance in the main energy. The components needed in building this system are a microcontroller, sensors, relays, water pumps, solar cells, and batteries. The test results of the DS18B20 temperature sensor have an accuracy of 98.99%, the humidity sensor has an accuracy of 86.94% and the soil pH sensor has an accuracy of 98.22%. With this system, information on the condition of tin plants can be found through the Blynk application. The hope is that this tool can help plant owners to monitor their plants and can optimize plant growth with good care.

Abstract

Along with the development of technology, the application of technology in agriculture is veryimportant. Due to the increasing need for plant monitoring and care. Fertilizer watering is usually donemanually, this method is less effective because the selection of fertilizers is not in accordance with soilconditions and farmers often forget the fertilization schedule that should be done on time. Based on previousstudies, the fertilization system designed only works based on scheduling indicators without paying attention toindicators of the soil condition itself. This will result in an unfavorable impact on tomato plants due to errors ingiving the type of fertilizer. Therefore, an automatic plant fertilization system is needed that is equipped with amonitoring system via the internet and pays attention to indicators of the condition of soil nutrients, so that thequality of plants can increase and make the work of farmers easier. This tool consists of a PH sensor thatsupports Android as a PH indicator, a RTC as an instruction for scheduling time, a 12V DC pump for thefertilizer water process, a relay as a connector and performance breaker for the pump, and an ESP8266 MCUNode as a microcontroller programmed to. Run the tool and regulate the fertilizer application process. From thissystem, it is hoped that it will make it easier for farmers to schedule fertilization and at the same time know thePH value of the soil to determine the type of fertilizer needed.

Abstract

Tanaman tin memiliki nilai ekonomis yang cukup tinggi karena terdapat manfaat bagi kesehatan mulai dari daun maupun buahnya. Tanaman tin akan menghasilkan buah yang berkualitas jika dirawat dengan baik, tetapi jika tidak dirawat dengan baik daun tanaman tin akan mudah layu dan pertumbuhannya lambat bahkan bisa saja mati. Untuk itu perlu proses penyiraman dan pemupukan secara teratur. Penelitian ini bertujuan untuk menyiram dan memupuk tanaman secara otomatis agar tanaman tin dapat tumbuh dengan maksimal. Sistem ini menggunakan ESP32 sebagai mikrokontroler yang terhubung dengan sensor soil moisture. Sensor ini digunakan untuk mengukur kelembaban pada tanah tanaman tin, ketika kadar kelembaban tanah dibawah 50% maka pompa akan aktif untuk melakukan penyiraman. Penyiraman dilakukan melalui pompa ke misting sprayer yang mana membuat air yang mengalir dari pipa dapat tersebar merata. Dari pengujian yang dilakukan dimana sensor soil moisture memiliki tingkat akurasi adalah 95,75%. Pemberian pupuk dilakukan apabila sudah masuk proses penjadwalan yang dilakukan oleh modul Real Time Clock (RTC) sebagai set waktu pada pemupukan yang rutin dan terjadwal dengan delay intruksi adalah 16,8 detik. Nilai pH akan tampak pada layar LCD dengan tingkat akurasi dari sensor pH tanah supp2787 mencapai 98,40%.
