Abstract

Rice is one of the most important cultivated plants in human civilization. One of the most important post-harvest processes is drying. Therefore, we need a drying process with an artificial heat source that can be adjusted to achieve constant heat according to the temperature characteristics of the rice. By applying the Fuzzy-MIMO control system, rice drying is expected to work quickly without damaging the rice foam. Fuzzy-MIMO system is translated into a rule based on the fuzzy algorithm that has been created. The fuzzy-MIMO method used is the Sugeno method with input temperature errors and humidity errors and outputs in the form of heat and wind gusts. The temperature sensor used has an error factor of 3.61%. The expected control system is a heating system and a motor to regulate the wind gusts in the drying chamber. The total drying time produced is 240 seconds with a moisture content of 15.2%. Drying time is influenced by the initial moisture content of rice.

Abstract

Flooding is a natural phenomenon that occurs as a result of high rainfall resulting in excess water that is not accommodated by the system. In general, the impact of floods can be detrimental to the community, especially people who live on the outskirts of the river. Jember Regency is one of the regencies that has many rivers that have the potential to not be able to accommodate water in the rainy season, resulting in flooding, one of which is the Kalijompo River, which floods almost every year. The impact of flooding can be minimized with good development and an early warning system for residents. Technology is one way to make human work easier, one of which is to monitor a situation. The application of river flow monitoring technology can reduce the detrimental impact of flooding. This technology provides information to residents about water levels. The technology applied has sensors that can monitor the height of the river flow, the height of the river flow consists of four levels, namely normal to dangerous which is marked by an alarm sound, so that when a flood occurs at night residents can get up immediately to save themselves, then the detrimental impact of flooding can be reduced.

Abstract

Hutan merupakan sumber daya alam yang tidak terbatas dan mempunyai manfaat yang sangat besar terhadap kehidupan makhluk hidup, namun keberadaan hutan saat ini sangat memprihatinkan akibat laju deforestasi dan degradasi yang sangat tinggi. Salah satu penyebab utama gangguan hutan adalah kebekaran. Kebakaran hutan akan menyebabkan kerugian lingkungan dan kerugian ekonomi. Oleh karena itu untuk mengurangi kerugian yang disebebkan oleh kebakaran hutan diperlukan penanganan yang cepat untuk menghindari meluasnya kebakaran hutan. Permasalahan dalam penanganan kebakaran hutan adalah lambatnya pemberitahuan mengenai informasi terjadinya kebakaran. Keadaan tersebut dikarenakan tidak adanya jaringan atau sinyal internet di kawasan hutan, serta indikator dan notifikasi kepada penjaga hutan. Sehingga dirancang sebuah alat pendeteksi dini kebakaran hutan untuk mempercepat proses tanggap bencana kebakaran hutan dengan mendeteksi level bahaya kebakaran menggunakan logika fuzzy, menyalakan LED dan bunyi buzzer pada indikator alat serta mengirimkan notifikasi via aplikasi bot telegram. Hasil dari alat ini sesuai dengan rancangan dan rule base yang telah dibuat yaitu pada kondisi aman didapat hasil nilai defuzzyfikasi sebesar 0-20. Kondisi siaga 1 didapat hasil nilai defuzzyfikasi sebesar 20-40. Kondisi siaga 2 didapat hasil nilai defuzzyfikasi sebesar 40-60. Kondisi waspada didapat hasil nilai defuzzyfikasi sebesar 60-80. Kondisi awas didapat hasil nilai defuzzyfikasi sebesar 80-100. Serta mampu memberikan indikator pada alat dan mengirimkan notifikasi via aplikasi bot telegram yang sesuai dengan level bahaya yang terdeteksi ke penjaga hutan.

Abstract

The need for electrical energy in remote areas to improve community welfare must be a concern for universities. The government's ability to build new electricity sources is very minimal because it requires large infrastructure and costs, but the government continues to strive to develop new power plants. Therefore, it is necessary to strive for innovation to build power plants from renewable energy sources. There is a need to use renewable energy as an alternative to replace electrical energy which is increasingly in crisis. One alternative energy that is easy to make is energy that uses magnetic force as a model for generating electricity. Brushless Direct Current (BLDC) motors are an alternative to current DC motors. This three-phase permanent magnet axial flux generator is specially designed for vertical-type wind turbines. This generator consists of two stators and one rotor. where each stator consists of 9 coils and the magnet used is a neodymium permanent magnet. Based on test results, this generator can produce a voltage of 12.57 VDC with a wind speed of 6.84 m/s. So, it can turn on DC lights and charge DC batteries. This three-phase axial BLDC generator was tested in 3 stages, namely without load, using battery load, and DC-light load with wind conditions depending on natural conditions.

Abstract

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

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.
