Permasalahan yang sering terjadi sekarang ini adalah tekanan air yang menurun pada saluran air saat beberapa kran dibuka sehingga hal itu menyebabkan pengisian air yang cukup lama. Agar tekanan pada pipa konstan, maka solusi dari masalah ini yaitu diperlukan suatu sistem pompa air untuk mengatasi tekanan air yang menurun ketika jumlah keran yang dibuka bervariasi yang dapat dimonitoring dari jarak jauh pada sistem instalasi air. Pada Tugas Akhir ini dirancang sebuah sistem untuk mengatur tekanan pompa air pada saluran pipa air dengan menggunakan tiga valve berbasis Internet of Things (IoT). Parameter tekanan dibaca menggunakan sensor tekanan yang keluarannya diolah dan dikalibrasi menggunakan arduino uno. Hasil keluaran digunakan sebagai parameter untuk mengatur kecepatan pompa. Untuk memonitoring sistem ini menggunakan nodeMCU ESP8266 agar dapat mengirim data ke android. Data dari bagian sensor monitoring dan alat pengontrol akan diproses oleh nodeMCU ESP8266, kemudian data akan dipublikasikan sehingga dapat dipantau menggunakan android. Tampilan pada sistem monitoring ini dibuat pada mit app inventor. Sebelum menyalakan sistem maka diatur set point tekanan minimal, maksimal, dan batas kerja sensor. Ketika tekanan kurang dari set point yang ditentukan, maka kecepatan motor akan terus bertambah. Ketika tekanan tepat pada set point maka kecepatan motor tetap. Ketika tekanan lebih dari set point maka kecepatan motor akan berkurang, dan ketika tekanan melebihi batas kerja sensor maka motor akan mati. Dengan sistem ini maka tekanan pada pipa air minum bisa stabil sesuai kebutuhan. Kata Kunci: Pompa Air, Monitoring, Internet of Things (IoT), Sensor Pressure. Tekanan Stabil
The development of installed capacity in power plants in 2018 was 41.696 MW or increased from the previous year in 2017 amounted to 39.652 MW (PLN Statistics, 2018). This has an impact on the reduced availability of fuel due to overexploitation. The highest energy sold per customer group in 2018 was the household customer group that was 41.7% higher than the industrial sector customer group by 32.8% (PLN Statistics, 2018). At present the use of electronic equipment for household needs is increasingly diverse. Many equipment that is often used in daily life is electronic equipment that is inductive load. Inductive load causes the value of the power factor to fall so that the power usage (Watt) becomes less than optimal. To overcome the problem caused by the large number of inductive loads a reactive power compensator is needed which is to use a capacitor. In this final project, a system designed to be able to measure and correct power factors automatically uses the Neural Network method and can monitor power online based on IoT. The results of testing the power factor improvement system were 97.8% successful in the trained electric load and 94.8% in the untrained electrical load.
A home state monitoring is important for homeowners. Because in Indonesia, theft and fire are common occurrences. This is caused by the negligence of homeowners. Therefore, home security monitoring systems are made to minimize theft and house fires. In this study, home security monitoring systems were made using human motion detection sensors or PIR (Passive Infrared Receiver) sensors, temperature sensors, flame detectors, buzzers, and pumps. The PIR sensor is used to detect thieves so buzzer can sound. The Temperature sensor and flame detector are used to detect fires then the pump will extinguish the fire. The system is then integrated with android HP devices, so homeowners can monitor the home wherever and whenever. From the test results, PIR sensor can detect human movement with a distance of 3.4 meters and the angle is 90o. The Temperature sensors and flame detectors detect temperatures and hotspots with a maximum distance of 25 cm, respectively
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
