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.

A tornado is one weather process that arises due to atmospheric instability. A tornado is a strong wind, but not all strong winds are tornadoes. Tornadoes have a short time frequency but can result in no minor disaster because they can blow objects away and uproot trees. Due to the consequences, an early warning system is needed as an anticipation for the community in the affected areas so that it can help the community by warning early on of the occurrence of a tornado. The ANFIS (Adaptive Neuro Fuzzy Inference System) method is used to forecast the event of a tornado, and the parameters used are wind speed, ambient temperature, and ambient humidity. This study will compare the ANFIS method using hybrid and backpropagation algorithms. Using the backpropagation algorithm, an error of 0.42385 was produced during training and testing, and an average error of 136.54 was obtained. When using the hybrid algorithm, the error during training is 2.0781 x 10-5, and the average error during testing is 0.015%.Keywords — ANFIS ; Anemometer; DHT22; Early Warning System; Tornado.

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.

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%.

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.
