Abstract

Now the development of smart phone technology has evolved rapid, especially Smartphone Android. Where multiple sensors embedded in a mobile phone, primarily an accelerometer sensor support be used of smartphone phone. Accelerometer is used to measure the acceleration reviews Angle X, Y and Z smartphone. So that the sensor is used to review the Movement Robot Arm matching is done with corner acceleration motion X, Y and Z smartphone Method on the system is backed with Fuzzy Logic the which serves to Determine the movement of the robot arm that is sent to the microcontroller. Arm robot system is processed using Matlab 6.1 and using the Software Arduino, and then implanted into the microcontroller, so that the robot goes According movement. Keywords : Android, Accelerometer, Robot Arm, Fuzzy Logic

Abstract

Air mancur banyak digunakan untuk memperindah suatu tempat agar tempat tersebut lebih menarik, pancaran air mancur yang banyak digunakan di taman-taman tidak bervariasi sehingga hiasan taman dalam kurun waktu yang lama akan membuat tempat tersebut kurang menarik. Oleh karena itu dibutuhkan suatu alat pengontrol bentuk semburan pada air mancur,dengan pola semburan air bervariasi sesuai dengan irama music yang bervariasi sehingga lebih atraktif dan menarik serta sewaktu waktu bisa diubah sesuai yang diinginkan. Music hanya mengiri air mancur bukan mengikuti air mancur. Air mancur dapat dibuat bergerak mengikuti pola-pola yang telah ditentukan. pola-pola tersebut tidak selalu sama dan akan selalu berubah setiap saatnya. Agar air mancur dapat bergerak sesuai dengan pola-pola yang diinginkan, pengerak berupa motor ditambahkan pada penyemburan air mancur, sehingga pergerakkan air mancur lebih dinamis.

Abstract

Fingerprint recognition system aims to identify someone. The main obstacle in recognizing a person's fingerprints is that the image has a low quality. The quality is caused by the type of oily, dry, dirty skin and the type of fingerprint scanner used. For this reason, an increase was made with the aim of improving fingerprint images as the main factor determining the level of accuracy of fingerprint image recognition results. In order for fingerprint images to be easily interpreted by humans and machines, it is necessary to improve quality by clarifying the fingerprint line. This study aims to improve the quality of fingerprint images with the Minutiae Extraction algorithm and the Learning Vector Quantization (LVQ) method as a test. This test is carried out using 4 images as training in each class. The total number of classes in this test is 10 classes with each class consisting of 10 images. In testing 75 fingerprint image data obtained an accuracy rate of 83.3333%.

Abstract

Railroad crossing security on highways is an important issue for road user safety. The current security system still has limitations, such as a lack of timely response and negligence of crossing guards, resulting in a high number of accidents at railroad crossings, which often claim lives. The high rate of accidents that occur today causes safety to be one of the most important things. Therefore, it is necessary to apply sophisticated technology to minimize the risk of accidents. The utilization of computer technology in the railway crossing security system can be an optimal solution. The system will work by using sensors that are able to detect the arrival of trains and send information about the state of the crossing to the crossing guards in real time. Thus, the crossing guards can take appropriate and quick action if there is a malfunction in the system. By integrating advanced technology, it is hoped that accidents at railway crossings can be minimized and the safety of road users can be guaranteed.

Abstract

The increase in online buying and selling due to government appeals during the Covid-19 pandemic has created a new habit in society, which also serves to reduce physical contact and prevent the spread of the virus. However, with the increase in delivery of goods, challenges arise in maintaining the cleanliness and safety of received packages. To address this, a smart package receiving system was developed that features automatic sterilization using ultraviolet (UV) lights and disinfectant spraying on incoming packages. This system aims to prevent the transmission of viruses that may be attached to the package. In addition, the system helps monitor and secure packages, especially when the owner is not at home. The system uses a microcontroller as the control center, equipped with an ESP32-CAM camera to document photos of the sender, as well as an ultrasonic sensor to detect whether the package is in the box or not. The process starts when the courier presses the “there is a package” button, which sends an OTP code to the receiver's Telegram. The courier enters the OTP code, places the package in the box, and closes it. After that, the UV lamp turns on for sterilization, the ESP32-CAM photographs the package, and the ultrasonic sensor detects the package status. If the package is detected, a photo notification of the sender is sent to Telegram, informing the recipient that the package is ready for pickup.
