Abstract

n electrocardiogram (ECG) is a signal that describes the heart’s electrical activity. Signal processing techniques are necessary to extract meaningful information from ECG signals. Researchers often use large databases like the PhysioNet database to evaluate the performance of algorithms. However, these databases have limitations concerning the lack of temporal or morphological variations. This study addresses this limitation by introducing a synthetic ECG capable of producing both normal 12-lead ECG signals and abnormal ECG signals and implementing it into the microcontroller. The primary contribution involves developing a synthetic ECG model using McSharry's dynamic equation model and implementing it using Mikromedia 5 for STM32F4 Capacitive as a microcontroller. This model enables users to set the desired heart rate and accurately replicates ECG waveforms using parameters ????????, ????????, and ????????, each determines the peak’s magnitude, the peak’s time duration, and the angular velocity of the trajectory. The synthetic ECG was evaluated qualitatively and quantitatively, demonstrating waveform similarity to the ECG signals. This study implies that the synthetic ECG model serves as a valuable tool for researchers and practitioners in electrocardiography. It enables the generation of normal and abnormal ECG signals, aiding in algorithm development and potentially enhancing the understanding and diagnosis of heart conditions.

Abstract

In this paper discussed the planning of export custom motorcycle products in the company Deus Ex Machina. in this study the data used were data about the product and the export sales history of deus ex machina in Bali. In planning this export, we determined that the products to be exported were our own style custom motorbikes, because the regulations were in effect, the products to be exported had to be in the form of spare parts, with the aim of targeting market in Japan. Keyword: Custom motorcycle, Deus ex Machina, Export, L/C, spare parts.

Abstract

Cv. Mustika Sarana is a private service company engaged in the delivery of goods or expedition. Cv. Mustika Sarana is a freight forwarder from Jakarta with the aim of sending goods to several major cities on the island of Sumatra. Some of the destinations for delivery of goods include the cities of Lampung, Palembang, Jambi, Pekanbaru, Bukittinggi, and the city of Padang by land route. Currently the company is still not optimally computerized in the field of recording data and transactions, which causes frequent occurrences, errors in recording, data loss, and delays in reporting. Data processing is very influential on a company, because by having fast and accurate data processing, a lot of information can be taken from the data. If the company does not manage data optimally it will have a direct impact on senders and potential senders. Because the sender of the goods cannot know the condition of the delivery status of his goods and the prospective sender does not have an idea of the price, delivery destination, delivery route and duration. The purpose of this research is to create a Website-Based Goods Delivery Information System using the extreme programming (XP) method. The resulting delivery information system can be used to record shipping transaction data and shipping transaction information that is equipped with the status of the goods. So that the problems that exist in the Cv. Mustika Sarana can be overcome with this goods delivery information system.
