Abstract

The use of electric cars as a means of transportation for pediatric patients has the main purpose of having a positive effect on the psychology of pediatric patients before surgery. Therefore, it is expected to accelerate the healing process. An electric car navigation system that can recognize the environment is needed. This article aims to develop a camera-based semi-autonomous navigation system using the faster R-CNN method to detect markers as electric car direction. This method optimizes the range of interest (RoI) layer to produce optimal features. Faster R-CNN is faster in generating accurate region proposals compared to R-CNN and Fast R-CNN. Various Faster R-CNN models were tested in image data processing for marker detection as the electric car steering system. Test results on FPS variations show that the best results were obtained when using the Faster R-CNN MobileNet V3 Large 320 FPN model with a value of 11.3f ps for the forward marker, 18.9 fps for the stop marker, 22.6 fps for the left turn marker and 11.1 fps for the right turn marker. With this model, the results obtained are quite good in testing the performance of the car navigation system. The results obtained in the success of the test are 70% for the forward marker test, 100% for the stop marker test, 90% for the left turn marker and 100% for the right turn marker.

Abstract

Salah satu pembahasan dalam penelitian mobil listrik adalah sumber energi atau baterai. Baterai pada mobil listrik mempunyai kapasitas yang terbatas sehingga harus dilakukan pengisian ulang agar mobil listrik tetap bisa berjalan jauh. Keadaan ini bila tidak segera diatasi bisa menyebabkan baterai tiba – tiba habis ditengah jalan. Tentu hal ini membuat cemas dan tidak nyaman bagi pengguna mobil listrik. Oleh karena itu diperlukan peramalan kapasitas baterai agar diketahui kapan waktunya untuk mengisi ulang baterai atau bahkan menggantinya. Penelitian ini membahas peramalan kapasitas baterai mobil listrik berbasis kecerdasan buatan levenberg marquardt neural network, serta membandingkan dengan sistem recurrent neural network. Kondisi mobil listrik menggunakan tiga kondisi beban yaitu kecepatan maksimal, akselerasi awal, dan tanjakan. Hasil penelitian menunjukkan peramalan sisa kapasitas baterai saat kecepatan maksimal setelah pemakaian selama 30 menit, sisa kapasitas baterai yang dapat digunakan diramalkan dengan backpropagation sebesar 61 Ah, dengan recurrent sebesar 60,5 Ah. Sedangkan target kapasitas sebesar 59,6 Ah. Sehingga metode terbaik dalam meramalkan kapasitas baterai adalah menggunakan recurrent neural network. Kata Kunci: Baterai lead acid, levenberg marquardt, mobil listrik, neural network, peramalan.

Abstract

Addiction to gadgets or devices can occur in children or adults. Addiction can happen to anyone, whether they are children or adults. So, if someone becomes addicted to gadgets. The cause of gadget addiction is the habit of interacting without rules, leading people to increasingly feel the pleasure and addiction of interacting in the virtual world. Gadget addiction is very dangerous when experienced by children because it poses problems for them including a lack of socialisation with friends as they already have virtual friends, not communicating with those around them, and health issues such as eyesight problems that can affect a child's emotional stability. From these issues, it is necessary to educate parents to always accompany and limit their children while playing with gadgets. Many parents do not understand how to support their children while playing with gadgets, which is one of the challenges faced by parents at Khodijah 112 Dadapan Kindergarten. Therefore, it is important to raise awareness among parents about how to support their children so that they do not become addicted to gadgets and how parents can understand their children's learning methods to improve their academic performance.

Abstract

KKN is activities carried out by students to integrate academic learning with practical experience in the field. Students who undergo KKN will socialize with the surrounding community, identify problems that occur at the KKN location, and find solutions that are relevant to these problems. The results of problem identification by students in Bungatan Village were the lack of public concern for environmental cleanliness and the absence of a Garbage Disposal Site. For this reason, group 160 KKN students stationed in Bungatan Village held a socialization activity on Bungatan Can Clean from Garbage (Busa-Busa). The activity aims to provide knowledge to the Bungatan Village Community regarding the types of waste, how to manage it, and invite all elements of the village apparatus to hold TPS and waste management from TPS to TPA. After this activity, it is hoped that the Bungatan Village Community will become more concerned with the surrounding environment.

Abstract

Wind energy as an alternative energy to meet the increase in energy. However, in places with limited wind quality, it is necessary to install suitable wind turbines to generate optimal power. Installation of a vertical axis wind turbine Savonius can be carried out at unstable wind speeds. PID controllers work well when the wind is stable, but not when the wind speed changes drastically. Automatic adjustment of the angle value on a Savonius type vertical axis wind turbine is required to produce a constant output power of 20kW using a fuzzy logic controller (FLC). The membership of FLC is determined from the methodology of measuring wind speed at the calculated distance and statistical analysis of wind variability. In this way, it is possible to anticipate the response of the actuator to the gust of wind to the rotor. The test results showed that the smaller the wind speed that enters the turbine, the greater the angle of the blades. Conversely, the greater the wind speed that enters the turbine, the smaller the angle of the blades. The control results show that the resulting pitch angle parameter has a value ranging from 0 to 18.428 degrees, with a wind speed value interval of 0 to 5 m/s. The input wind speed value of 5 m/s by controlling the angle of 18.428 degrees aims to maintain the generated power value of 20,000 watts. The purpose of this research is to increase the output power and reduce the risk of rotor damage due to vibrations.
