Abstract

Sistem monitoring greenhouse adalah alat yang bekerja untuk memantau dan mengamati kondisi di dalam greenhouse baik suhu, intensitas cahaya, kelembaban udara dan kelembaban tanah. Sistem monitoring ini terhubung secara wireless dengan menggunakan teknologi Zigbee dan terhubung dengan aplikasi IoT (Internet of Things) open-source yaitu thingspeak menggunakan jaringan seluler. Penelitian ini dilakukan untuk menguji dan menganalisis kinerja dari aplikasi IoT ketika dijalankan menggunakan jaringan seluler untuk mengetahui pengaruh dari kekuatan penerimaan sinyal terhadap delay, packet loss dan Throughput. Berdasarkan hasil pengujian ditemukan bahwa standar jaringan yang digunakan hanya mempengaruhi banyaknya TCP Error pada jaringan 3G dibandingkan jaringan 4G. Tetapi standar jaringan tidak mempengaruhi kinerja dari pengiriman data jika dilihat dari sisi delay yang berada diantara 0.5 ms sampai dengan 1.5 ms di kedua kondisi, packet loss yang hanya terjadi 1 kali dari seluruh 6 percobaan yang dilakukan dengan jumlah packet loss hanya sebesar 2%, dan throughput yang relatif sama diantara 9.7 sampai dengan 22 kbit/s. Sedangkan kekuatan sinyal atau besar dari nilai RSRP (Reference Signal Received Power) tidak mempengaruhi jumlah TCP Error yang berada diantara 1 sampai 4 error di seluruh kondisi dan tidak mempengaruhi packet loss dimana packet loss tidak terjadi di seluruh kondisi pengujian. Nilai RSRP hanya mempengaruhi delay dan throughput dan hanya pada kondisi low dimana pada kondisi sinyal low, terjadi peningkatan delay dari rata-rata 1 ms pada kondisi high dan moderate menjadi rata-rata 1.5 ms pada kondisi low, dan throughput yang berada diantara 10 sampai 16 kbit/s pada kondisi high dan moderate menjadi 6 sampai 15.4 kbit/s pada kondisi low.

Abstract

Using solar energy as a source of electricity has great potential. A boost converter is needed to overcome the low energy conversion efficiency of solar panels. Many boost converters have been used to achieve high efficiency, one of which is the quadratic boost converter. This study aims to increase the efficiency of solar panel output at low inputs. An overall study of the system with a lamp load of 2 volts from 09.00 WIB to 15.00 WIB showed that the highest efficiency was achieved at 10.15 am at 99% with an average efficiency of 80%. At the same time, the output voltage is 24.64 volts. From the voltage and current obtained simultaneously, the input power is 2.99 watts and the output power is 2.97 watts. From the tests I did, it appears that the quadratic boost converter can provide a fairly high output voltage. Low-duty cycles have been shown to produce higher output voltages than traditional boost converters.

Abstract

Penelitian ini merancang sistem monitoring debit air menggunakan flowmeter ultrasonik clamp on yang terintegrasi dengan NodeMCU dan aplikasi Android melalui platform Blynk. Sistem ini mengukur debit air secara real-time dan menampilkan data pada LCD serta aplikasi mobile. Komunikasi antara flowmeter dan NodeMCU difasilitasi oleh modul RS485 to TTL untuk memastikan akurasi. Pengujian menunjukkan tingkat error yang rendah, dengan maksimum 0,13% pada komunikasi flowmeter ke NodeMCU dan 0,54% pada pengiriman data ke aplikasi Android. Sistem ini secara efektif menyediakan monitoring real-time yang akurat untuk aplikasi industri dan lingkungan.

Abstract

The VRLA battery charging process using a Switch Mode Power Supply (SMPS) in this test plays a very active role in maintaining battery reliability. In the SMPS there are CC and CV that regulate a stable current at 1.8 Amperes and a voltage at 14.1 volts. Charging is integrated with the IoT system by utilizing Arduino mega communication with esp32 which is connected to the application for monitoring and controlling the cut-off relay. The esp32 Rx is connected to the Arduino mega tx and the esp32 tx is connected to the Arduino rx which makes both communicate two-way. Charging an 18Ah battery takes place for 2 hours and 16 minutes with an initial voltage of 13.44 volts, a stable current of 1.787 amperes, and a duty cycle of 21.24% in CC mode, while CV mode starts at a voltage of 14.1 volts with a current slowly decreasing to 0.3 amperes and approaching the automatic or manual cut-off relay switching mode to continue charging the 2nd battery, namely 5Ah. The 5Ah battery charging process is faster due to its smaller capacity and higher initial voltage compared to 18Ah, so the charging time is only 45 minutes. In this study, the cut-off relay switching and monitoring system works very well with a small error of 0.55% and a fast switching time of 1.3 seconds.
