Abstract

Penelitian ini menerapkan teknologi WSN dengan modul Long Range (LoRa) karena dapat digunakan untuk memantau keadaan rumah burung walet yang jauh. Keadaan rumah burung walet dilakukan pengumpulan informasi menggunakan sensor DHT11 dan BH1750. Kegunaan sensor tersebut diantaranya DHT 11 untuk mendata suhu dan kelembapan, BH1750 untuk mendata intensitas cahaya. Sensor tersebut diletakkan pada setiap lantai yang berjumlah 3 lantai di rumah burung walet tersebut. Data sensor dikirimkan melalui komunikasi LoRa (Long Range). Analisa pada penelitian ini, diantaranya melakukan perhitungan dan pengukuran RSSI (Received Signal Strength Indicator) komunikasi LoRa dengan variasi jarak komunikasi. Variasi jarak propagasi komunikasi yang digunakan diantaranya 100m, 500m, 1000m, dan 1600m.  Sebagai hasil penelitian, RSSI komunikasi LoRa terhadap variasi lokasi sink pada setiap lantainya ditunjukkan bahwa semakin rendah ketinggian sink tersebut maka nilai RSSI semakin kecil. Error persen RSSI antara perhitungan dengan pengukuran, menunjukkan semakin rendah ketinggian sink maka error persen RSSI semakin kecil. RSSI komunikasi LoRa terhadap variasi jarak propagasi komunikasinya menunjukkan bahwa semakin jauh jarak propagasi maka RSSI semakin kecil. Perbandingan error persen RSSI pada komunikasi LoRa diantaranya sink 1 didapatkan 5,6%, sink 2 didapatkan 2,5%, dan sink 3 didapatkan 3,5%. Sehingga dari nilai tersebut dapat mengetahui jarak penerimaan data propagasi komunikasi LoRa untuk memantau kondisi lingkungan pada rumah burung walet. This study implemented WSN technology with a Long Range (LoRa) module because it can be used to monitor the condition of a distant swiftlet nest. The condition of the swallow house was collected using DHT11 and BH1750 sensors. These sensors include DHT 11 to record temperature and humidity and BH1750 to record light intensity. The sensors are placed on each of the three floors in the swiftlet house. Sensor data is sent via LoRa (long-range) communication. The analysis in this study includes calculating and measuring the RSSI (Received Signal Strength Indicator) of LoRa communication with variations in communication distance. The variations in communication propagation distance used include 100 m, 500 m, 1000 m, and 1600 m. As a result of the study, the RSSI of LoRa communication against variations in sink locations on each floor showed that the lower the height of the sink, the smaller the RSSI value. The RSSI percent error between calculation and measurement shows that the lower the sink height, the smaller the RSSI percent error. The RSSI of LoRa communication against its communication propagation distance variation shows that the further the propagation distance, the smaller the RSSI. Comparison of RSSI percent error in LoRa communication: sink 1 obtained 5.6%, sink 2 obtained 2.5%, and sink 3 obtained 3.5%. From this value, we can find the distance from receiving LoRa communication propagation data to monitor the swiftlet house's environmental conditions.

Abstract

In current environmental conditions, air quality is often underestimated even though it is crucial for the survival of living organisms. Good air quality that contains sufficient oxygen for breathing and photosynthesis, as well as stable carbon dioxide levels, is essential for humans, animals, and plants. Pollution factors such as motor vehicle exhaust, factory emissions, and waste burning can reduce air quality and thus have an indirect impact on the health of living beings. This research focuses on air pollution caused by carbon monoxide and carbon dioxide, using the Mamdani fuzzy method to determine uncertainty and vagueness values. An IoT system with two LoRa devices is used to monitor air quality, with data from sensors represented via MATLAB using fuzzy logic for more accurate results. LoRa device integration with Arduino and ESP32 can be used for accurate sensor reading and communication, ensuring proper data transmission between nodes and gateways for real-time monitoring and comparison of gas parameters at different locations. The reading results from the sensors and the monitoring results on the Blynk platform show identical values with 0% error from monitoring. For the percentage of ISPU values from simulation results in MATLAB compared to manual calculations, there is a difference of 1.12% when compared with the reading values from the sensors.

Abstract

Pencemaran udara yang berasal dari industri, transportasi, dan aktivitas sehari-hari menyebabkan meningkatnya kadar gas CO dan CO2 di udara. Sebagai respon terhadap hal tersebut, telah dirancang suatu sistem monitoring gas CO dan CO2 berbasis LoRa yang menggunakan dua buah sensor, yaitu MQ-7 dan MQ-135, untuk mengukur gas-gas tersebut. LoRa dapat mengirimkan data jarak jauh dengan perangkat LoRa lainnya, sehingga digunakan Sensor Node untuk mendeteksi gas CO dan CO2 pada area tertentu, dan Gateway Node untuk menerima data dari Sensor Node. Hasil penelitian menunjukkan bahwa pada kondisi Line of Sight (LOS), jarak maksimal yang dicapai adalah 800 meter, sedangkan pada kondisi Non-Line of Sight (NLOS), jarak maksimal yang dicapai adalah 500 meter. Pada pengujian perubahan nilai bandwidth, jarak maksimal tanpa encoding adalah 800 meter; dengan bandwidth 62,5 dan 250 kHz, jarak maksimal menjadi 500 meter, dan dengan 500 kHz, menjadi 700 meter. Terlihat bahwa pada kondisi LOS, penurunan nilai RSSI dan SNR lebih stabil dibandingkan pada kondisi NLOS. Hal ini dikarenakan tidak adanya halangan yang dapat melemahkan sinyal, sehingga jarak yang dapat dicapai menjadi lebih jauh dibandingkan saat terdapat halangan atau pada kondisi NLOS. Selanjutnya, pengujian perubahan nilai bandwidth menunjukkan bahwa penurunan RSSI lebih stabil saat menggunakan bandwidth yang lebih besar. Selain itu, semakin besar bandwidth yang digunakan, semakin kecil nilai SNR yang dihasilkan, dan semakin jauh jarak yang dapat dicapai. Hal ini terjadi karena bandwidth yang lebih besar menghasilkan sinyal yang terdistribusi lebih merata. Penggunaan bandwidth yang lebih besar juga meningkatkan jumlah noise yang diterima di Gateway Node karena spektrum yang digunakan lebih lebar, sehingga cenderung menyebabkan nilai SNR menurun saat menggunakan bandwidth yang lebih besar.

Abstract

Technology that is growing rapidly and innovations that have sprung up in the electrical field today are driving the use of electricity as a source of energy to do work. Electric motor is one component that is very popular in the industrial world and households that are useful to human life. In addition to DC motors and induction motors, there are also 3 phase brushless direct current (BLDC) motors which are a type of synchronous motor where magnetic fields are produced by rotor and stator at the same frequency. The rotor is a moving part of the brushless direct current motor which is a place of permanent magnet called a pole. This paper discusses the performance of brushless direct current 3 phase axial flux motors with different diameters of neodymium type permanent magnets. Tests carried out using neodymium permanent magnets with diameters of 15mm x 2mm and 20mm x 2mm were tested without using a load and using load. The parameters used in testing motor performance include speed, torque, and motor power with a source voltage of 12V, 16V, 20V, and 24V. The test results shows that the speed value of a BLDC motor using permanent magnets with a size of 20mm x 2mm is greater than that of permanent magnets of 15mm x 2mm. The same thing applies to the value of the power produced while, for the value of torque when the motor uses a permanent magnet of 15mm x 2mm will be greater than that of a motor using a permanent magnet of 20mm x 2mm.
