Abstract

The purpose of this research is to determine the effect of the physical coding of LoRa communications on monitoring water pipelines. Optimizing the performance of packet receivers in the LoRa communication system using coding on the physical parameters SF (spreading factor), BW (bandwidth), and CR (coding rate). The detection system consists of 3 sensor nodes, 3 intermediate nodes, and 1 receiver node. Data from these sensors is sent to a cloud database. The SX1278 LoRa communication module works using a 433 MHz frequency. During the transmission process on the LoRa communication system, optimization is carried out for receiving data packets using the parameter coding method of physical spread factors, bandwidth, and coding rate. As a result of the research, it is shown that the greater the value of the third parameter (SF, BW, and CR), such as improvement in packet reception performance, improvement in bit security, and increasing packet resistance to various disturbances in transmission, but the time required for sending data be longer. The optimal parameters for detecting pipe leak locations include SF 10, BW 500 KHz, and CR 4/8. The LoRa SX1278 scenario is optimal with a distance of 400 meters, where packet and byte reception are obtained 100%.

Abstract

Abstract— Solar panels require performance monitoring when energy shortages occur in the area. Monitoring solar panels requires a detection device to detect solar panels, including the ACS712 current sensor for monitoring the output current of the solar panel, a DC voltage sensor for monitoring battery performance, and a DHT11 temperature sensor for monitoring the temperature of the solar panel storage battery. The WSN technology that can work is ZigBee communication. This ZigBee communication research uses various topology methods, including star, tree, and mesh topologies. Solar panel monitoring tests are carried out indoors and outdoors. The ZigBee communication device used is the XBee S2C device, which operates at a frequency of 2.4 GHz. From a comparison of various topologies, the mesh topology is a topology with good performance because it has the characteristic of choosing a router with the fastest path to reach the coordinator. It is proven by monitoring solar panels with an optimal distance of 80 m, which is carried out from outdoors with an RSSI value of -84 dBm, a throughput of 0.55 kbps, and a delay of 2.77 ms, producing power for 150 minutes with an average current of 0.14 A, voltage of 9.86 V, and temperature of 31.48°C. The number of disturbances and weather conditions greatly affect signal propagation, which can hamper the data transmission process. Throughput fluctuates due to uncertain weather conditions, and delay fluctuates due to a lot of interference from other radio signals.

Abstract

Budidaya ikan air tawar memiliki peran penting untuk mencapai ketahanan pangan di Indonesia. Ikan nila merupakan salah satu ikan air tawar yang diperoleh melalui aktivitas perikanan budidaya. Terdapat beberapa faktor yang memengaruhi pertumbuhan ikan nila, seperti kualitas air, proses pemberian pakan, dan kualitas pakan yang diberikan. Jumlah pemberian pakan yang terlalu sedikit dapat menyebabkan ikan nila mengalamai pertumbuhan lambat, sedangkan pemberian pakan yang terlalu banyak dapat menyebabkan kualitas air menjadi tidak baik karena ada pakan yang tidak dimakan atau terlambat untuk dimakan. Tujuan penelitian ini adalah untuk menganalisis penggunaan automatic feeder dibandingkan dengan cara konvensional, sehingga hasilnya dapat digunakan sebagai pilihan yang dapat diterapkan dalam perlakuan budidaya ikan tertentu untuk menghasilkan panen maksimal. Hasil dari penerapan teknologi tersebut menunjukkan efisiensi pemberian pakan mencapai 97,6%; tingkat kelulusan hidup sebesar 94,4%; dan laju pertumbuhan spesifik mencapai 3,58%. Hal tersebut lebih baik jika dibandingkan dengan beberapa perlakuan lain dalam budidaya ikan, sehingga dapat mengakibatkan hasil panen lebih cepat dengan penggunaan pakan yang efisien, dan jumlah panen yang maksimal.

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

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

Livestock products that experience an increase in production every year are dairy products. Based on research data on national milk production in 2020, the amount of dairy products produced increased to 947,685.36 tons. Animal protein needed by the body to grow and develop and to maintain health is the source of milk. The dairy processing industry relies on fresh cow's milk. Milk needs to be further processed to extend its shelf life because milk is easily spoiled or damaged and has a relatively short shelf life as a food of animal origin. Pasteurization is a process that can be done. One effort to extend the shelf life of milk is by pasteurizing milk. The pasteurization process is carried out by heating milk at a temperature of LTLT 62°C-66°C for 30 minutes or HTST temperature of 72°C -75°C for 15 seconds. This study uses the LTLT method with a temperature of 63°C to maintain the temperature using the 2nd 2nd-orderer Nichols PID control. To apply the system, several components are used, namely, Arduino nano as a microcontroller, DS18B20 sensor as a milk temperature reader, as well as a feedback system from PID control, servo to regulate the valve used to regulate the intensity of the stove flame, and the servo, rotates according to the PID value received, MQ-02 sensor to maintain safety against LPG gas leaks. There is a 12C LCD to provide visual information on the temperature and ADC values from the MQ-02 sensor, and there is a buzzer as an indicator of the system. The buzzer will be ON when the pasteurization process time is complete and when a gas leak occurs. Then, there is a TCS3200 sensor that compares the colour of the milk.

Abstract

The issue of waste management has become a critical topic, particularly in the sorting process, which relies on human labor and poses hygiene risks and inaccuracy. Several technologies have been explored to address this problem, including robotic arms with visual sensing, which are widely used but face challenges such as limited working areas and relatively complex installation processes. This study develops a waste-sorting robot based on a holonomic-wheeled robot integrated with visual sensing and the YOLOv5 algorithm for waste classification. The robot is equipped with a vacuum gripper for waste pickup and placement, as well as sensors for navigation and position control. Tests were conducted on four types of waste: bottles, leaves, metals, and paper. The results demonstrate a classification accuracy rate of 100%, with an average waste placement success rate of 90% for leaves and paper, and 80% for bottles, influenced by the surface characteristics of the waste and the consistency of the robot's positioning. This robotic system offers enhanced efficiency and accuracy compared to manual methods, although there remains room for improvement in the gripping mechanism and synchronization of the robot's movements. Overall, the robot system shows performance with accuracy above 80% with a wider working area than using a robot arm.
