Abstract

Vehicle classification and detection aims to extract certain types of vehicle information from images or videos containing vehicles and is one of the important things in a smart transportation system. However, due to the different size of the vehicle, it became a challenge that directly and interested many researchers . In this paper, we compare YOLOv3's one-stage detection method with MobileNet-SSD for direct vehicle detection on a highway vehicle video dataset specifically recorded using two cellular devices on highway activities in Medan City, producing 42 videos, both methods evaluated based on Mean Average Precision (mAP) where YOLOv3 produces better accuracy of 81.9% compared to MobileNet-SSD at 67.9%, but the size of the resulting video file detection is greater. Mobilenet-SSD performs faster with smaller video output sizes, but it is difficult to detect small objects.

Abstract

This study was conducted to gain a deeper understanding of how liquidity, as measured by the Current Ratio (CR), and profitability, as measured by Return on Assets (ROA), affect firm value, as measured by Price to Book Value (PBV), in pharmaceutical companies listed on the Indonesia Stock Exchange (IDX) in 2021–2024. This study used a quantitative method with a multiple linear regression analysis approach. The sample in this study consisted of 13 companies with a total of 52 observations obtained through a purposive sampling technique based on secondary data in the form of financial reports accessed through the official IDX website. The sample represents companies in the pharmaceutical subsector during the study period. The results show that the Current Ratio (CR) and Return on Assets (ROA) has a positive and significant effect on PBV. Simultaneously, CR and ROA also have a significant effect on firm value. This indicates that the level of liquidity and a company's ability to generate profits are important factors in increasing investor perceptions of firm value. These findings indicate that companies need to manage current assets efficiently and improve profitability to increase their market value.
