Abstract

Low Power Wide Area Networks (LPWAN) applications are a major concern in infrastructure. Rural are areas that have a poor quality signal; the cause lies in the location of the rural regions away from the coverage area Base Transceiver Station (BTS) so that the need for telecommunications equipment in the form of Global System for Mobile communications (GSM) repeaters. GSM repeater devices require an antenna that has a large gain mainly on the receiving antenna, one antenna that has a large gain character is helix axial mode has a large dimension resembling a spring and has a directional radiation pattern properties, whereas the antenna with an omnidirectional radiation pattern is a patch meander line antenna has compact dimensions and is easy to fabricate. The meanderline patch antenna has the disadvantage one of which is the small gain caused by trapped surface waves on the ground. This research will discuss the design and realisation of helix axial mode, and patch meanderline Defected Ground Structure (DGS) for Low Power Wide Area Networks (LPWAN) application in a rural area so it can be used for Internet of Things (IoT) based weather monitoring. Integrating antenna helix axial mode as receiving antenna and antenna patch meanderline DGS as rebroadcast antenna in GSM repeater able to make edge network in a rural area become High-Speed Packet Access + (HSPA +) network. The test result IoT based obtained the value of Received Signal Strength (RSSI) an average of -89 dBm in HSPA+ network.

Abstract

Kendaraan otonom adalah kendaraan yang dapat bernavigasi tanpa ada intervensi manusia. Istilah otonom tidak hanya diterapkan untuk mobil tanpa awak tetapi juga untuk alat pengolah tanah yaitu traktor. Tidak semua orang bisa mengoperasikan traktor, dibutuhkan keahlian khusus untuk mengoperasikan alat tersebut, terutama bagi penyandang disabilitas, alat tersebut akan sulit dioperasikan bahkan tidak mungkin dapat dioperasikan tanpa bantuan teknologi tertentu. Terdapat dua teknik untuk melakukan pengolahan tanah, setiap teknik tersebut menghasilkan pola pengolahan tanah tertentu, yaitu pola pengolahan tanah bolak-balik dan pola pengolahan berkeliling, pola pengolahan tanah berkeliling memiliki pola yang sama dengan pola gerak sirkular. Artikel ini menguraikan tentang algoritma navigasi otonom dengan menerapkan Finite State Machine untuk menghasilkan pola pengolahan tanah berkeliling atau pola gerak sirkular. Pola pergerakan yang dihasilkan menunjukkan hasil yang lebih baik jika antena modul GPS diletakkan di atas kendaraan dibandingkan diletakkan di depan kendaraan. Pengujian dilakukan sebanyak 5 kali pada setiap peletakkan GPS. Hasil pengujian pada saat GPS diletakkan di atas kendaraan adalah 4 diantaranya menghasilkan jejak pola gerak sirkular. Algoritma yang digunakan mampu menghasilkan pola gerak sirkular dengan jarak antar sirkular kurang lebih 3 sampai 5 meter.

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

The high level of consumption of chicken meat as one of the protein sources is the community's primary choice, so the breeding process becomes crucial. The hatching process requires a long time, and the results could be more optimal. Based on the explanation above, the study designed an egg incubator to hatch more eggs. The village area of Nongko Tempurejo District, Jember Regency, is one of the centers of boiler chicken cultivation. Chicken livestock still uses manual methods in egg-shaping, so egg hatching could be more optimal and requires special attention from farmers. Applying an automatic egg incubator is expected to help the productivity of egg hatching. The incubator was designed using a DHT11 sensor, AC Dimmer Light Module, Nodemcu, Arduino, DC Fan, RTC, and Motor Servo. The DHT11 sensor reads the temperature and humidity conditions in the egg incubator. The data is processed by the Arduino board and then displayed on the LCD, then sent using the ESP8266 module contained in the nodemcu board so that the appearance of the conditions in the machine can also be seen on smartphones with the BLYNK application. By using this technology, the success of egg hatching can reach 87%, up from 70% -80% if conventional methods are still manual, and breeders can focus their time on other things that need more attention. ABSTRAK Tingginya tingkat konsumsi daging ayam sebagai salah satu sumber protein menjadi pilihan  utama bagi masyarakat sehingga proses pengembangbiakan menjadi sangat penting. Proses penetasan membutuhkan waktu yang lama dan hasil penetasannya tidak maksimal. Dari penjelasan di atas penelitian dilakukan perancangan mesin penetas telur yang digunakan untuk menetaskan lebih banyak telur. Daerah Desa Curah Nongko Kecamatan Tempurejo Kabupaten Jember merupakan salah satu sentra budidaya ayam boiler, para ternak ayam masih menggunakan metode manual dalam pemetasan telur sehingga penetasan telur tidak maksimal dan membutuhkan perhatian khusus dari peternak. Penerapan teknologi penetas telur otomatis diharapkan dapat membantu produktifitas penetasan telur. Mesin penetas yang dirancangan menggunakan sensor DHT11, AC Dimmer Light Module, NodeMCU, Arduino, kipas DC, RTC dan motor servo. Sensor DHT11 digunakan untuk membaca kondisi suhu dan kelembaban yang ada di dalam mesin penetas telur, kemudian data diolah oleh board Arduino lalu ditampilkan pada LCD selanjutnya dikirimkan menggunakan modul esp8266 yang terdapat pada board Node MCU sehingga tampilan kondisi di dalam mesin juga bisa dilihat pada smartphone dengan aplikasi Blynk. Dengan menggunakan teknologi ini keberhasilan penetasan telur dapat mencapai 87% naik dari 70% - 80% jika menggunakan cara konvensional yang masih manual, dan peternak dapat menfokuskan waktunya kepada hal lain yang lebih membutuhkan perhatian mereka.

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

The increasing demand for reliable wireless communication in modern surveillance systems, particularly Closed-Circuit Television (CCTV), requires the development of antennas with high efficiency, wide bandwidth, and stable signal performance. To meet these requirements, this study presents the design and analysis of a 2×1 microstrip array antenna with rectangular patches that use proximity coupling, optimized for operation in the 2.4 GHz ISM band. The antenna was designed and simulated using CST Studio Suite to evaluate its electromagnetic characteristics, while measurements using a Vector Network Analyzer (VNA) were performed to validate the performance of the manufactured prototype. Simulation results show that the antenna achieves a reflection loss of −24.62 dB, a standing wave ratio (VSWR) of 1.12, and a frequency bandwidth of 159 MHz, indicating good impedance matching and wide operational capability. Meanwhile, measurement results showed a reflection loss of −12.59 dB, a VSWR of 1.15, and a frequency bandwidth of 86 MHz. Both simulation and measurement results showed directional radiation patterns, ensuring efficient energy radiation and better signal focus for monitoring coverage. The designed antenna also shows a measured gain of 9.25 dBi, exceeding the simulated gain of 6.99 dBi, confirming improved performance. The difference between simulation and measurement is mainly due to variations in substrate thickness, material tolerance, and environmental factors during testing. Overall, the proximal coupling approach has proven effective in improving coupling efficiency without adding design complexity. This antenna is well-suited for reliable and efficient data transmission in CCTV applications. Furthermore, the findings contribute significantly to advancements in antenna technology, particularly in the domains of wireless communication, IoT, and smart city-based surveillance systems.

Abstract

Indonesia, as an agrarian country, has a wide variety of horticultural commodities, one of which is mandarin orange (Citrus reticulata). Post-harvest handling, particularly the sorting process based on fruit ripeness and defects, plays an important role in maintaining product quality and market value. However, manual sorting is considered inefficient because it is repetitive, highly dependent on operator subjectivity, and prone to inconsistency. Several studies report those manual methods can result in classification error rates exceeding 20% and longer processing times compared to computer vision-based systems. This study develops an automatic citrus fruit quality classification system using the YOLOv5 algorithm. The dataset consists of 703 citrus fruit images captured directly using a webcam under varying lighting intensities and color conditions, and is divided into 80% training data and 20% testing data. The classification is performed into three quality categories: ripe, unripe (green), and rotten oranges, based on the visual characteristics of the fruit peel. Experimental results show that a training configuration with 300 epochs, a batch size of 40, and warm white bright lighting conditions achieves the best performance. Real-time testing on 15 citrus fruits yields an average accuracy of 78.2%, indicating the potential of the proposed system as an initial sorting aid, despite limitations related to lighting conditions and the amount of test data.
