Abstract

Tomatoes, as a type of vegetable or fruit, are often susceptible to damage, making handling them a complex challenge. Distinguishing between fresh and damaged tomatoes is very important, considering the significant impact on nutritional value and economic aspects. Traditional approaches via visual inspection have proven to be less efficient and inconsistent in their detection accuracy. To overcome this challenge, the use of images is a vital solution for distinguishing ripe, half-ripe and unripe tomatoes. In this context, HSI (Hue, Saturation, Intensity) calculations are applied to measure RGB color and room transformations. Images are extracted in jpg format, saved as training data, and this method is implemented using the Python programming language and GUI interface design in MATLAB. The research results show the HSI value for each class, with the ripe tomato class having an average hue of 0.0051 – 0.026, saturation 0.1862 – 0.3291, and intensity 0.0975 – 0.7522. Half-ripe tomatoes have hue 0.0208 – 0.0848, saturation 0.1346 – 0.5746, and intensity 0.1056 – 0.4714, while immature tomatoes have hue 0.0174 – 0.0689, saturation 0.0474 – 0.2072, and intensity 0.0595 – 0.3203. The integration of the HSI algorithm steps with the RGB color space provides an additional dimension to color analysis, which has the potential to increase the accuracy of tomato ripeness detection.

Abstract

This research was conducted to study the effect of pump speed on changes in fluid levels in the tank and linear regression analysis of fluid flow. The variation used is a 4 mm solenoid and a variable pump speed range of 30-50%. The results of increasing the level at a pump speed of 32% obtained a level of 82 mm and a pump speed of 50% obtained a level of 149.9 mm, with fluid flow rotation occurring in the first minute. In addition, the determination calculation uses actual fluid level data at time 0 seconds (n=1), time 60.27 seconds (n=30), and time 180 seconds (n=61), with a fluid level value of 1 mm, 118 mm, and 141 mm. So the determination evaluation (R2) obtained is 0.863, which indicates that the model is included in the high tolerance category.  So this indicates that the PID controller in this series of piping system equipment is still suitable for use because in the recording of the fluid flow data obtained no significant gaps were found. Apart from that, it can also be seen that the pump speed affects the fluid flow rate due to the change in mechanical energy into kinetic energy which pushes the fluid towards the tank. Process time also influences changes in fluid levels in the tank as a result.

Abstract

Brand competition in the children's bicycle industry at this time is increasingly fierce. PT X Manufacturing (PT X), which produces tricycles for children, has experienced a decline in sales and has not reached its sales target for the past three years. This study proposes strategies regarding brand awareness, perceivedquality, and internal and the company's external environment. These can be the company's strengths, weaknesses, opportunities, and threats. The hybrid method used in this study consists of the EFE matrix, IFE matrix, IE matrix, SWOT matrix, and QSPM. Data collection techniques used interviews, observations,and questionnaires. The results showed that PT X was located in the V-quadrant in the IE matrix. A suitable strategy was a hold and maintain strategy consisting of market penetration and product development strategies. Seven alternative strategies were formed through the SWOT matrix, and priority strategies weredetermined using the QSPM method. The priority strategy was utilizing online media to increase marketing and public awareness of product brands. This strategy was chosen as a priority because it has the highest value of 5.936.
