Abstract

Frekuensi angin puting beliung yang terjadi di beberapa wilayah di Kabupaten Jember menunjukkan bahwa Kabupaten Jember merupakan daerah yang rawan dengan bahaya angin puting beliung. Oleh karena itu, diperlukan sistem peringatan dini untuk menanggulangi bencana sehingga antisipasi warga dalam menghadapi bencana akan meningkat. Pada penelitian ini ditujukan untuk menghasilkan sensor DHT22 dan sensor anemometer dengan metode Jaringan Syaraf Tiruan Backpropagation yang dapat memberikan peringatan angin puting beliung sejak dini kepada masyarakat. Penerapan Jaringan Syaraf Tiruan Backpropagation digunakan untuk peramalan angin puting beliung dengan algoritma Levenberg-Marquardt. Hasil dari pembelajaran dengan menggunakan algoritma Levenberg-Marquardt didapatkan hasil terbaik Mean Squence Error (MSE) sebesar 3,6588 × 10-7 dengan rata-rata error dari setiap data pembelajaran sebesar ±2,61%.

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

This research uses two object detection algorithms, Faster R-CNN with ResNet50 backbone and YOLOv5, to develop an intelligent camera system for monitoring volcanic activities. The models were trained and evaluated using CCTV footage from Mount Semeru, a region prone to volcanic eruptions. Key performance metrics such as Precision, Recall, and mean Average Precision (mAP) were used to evaluate the performance of both models. The high precision numbers for YOLOv5 and Faster R-CNN show they are good at avoiding false positives, which is essential for volcanic monitoring. YOLOv5 has a precision of 83.2%, while Faster R-CNN is 84%. However, recall shows a more significant difference between the two models. Faster R-CNN has a recall of 82%, meaning it is better at detecting all relevant volcanic activities, even if that means catching a few false positives. The variations in performance can be attributed to their respective designs. YOLOv5 is designed to achieve rapid, real-time detection by simultaneously predicting bounding boxes and class probabilities. This approach enhances speed but may slightly reduce recall.  Faster R-CNN uses a two-stage process, tending to be more accurate but can be slower and less flexible across different IoU thresholds. Its higher recall means it catches more objects, contributing to its lower mAP@50-95 since it could struggle with overlapping or varying-sized objects.

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 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.
