Indonesia is one of the most prominent pepper producers and consumers worldwide. Indonesian pepper quality, however, is still low. The pepper’s low-quality problem is caused by the processing that still uses the traditional (conventional) method. This study reviews many techniques that have the potential to improve pepper quality. The review result from the references shows that waiting time (delaying) in the ripening process can increase the pepperine level from 4.33 % to 6.60 %. The pepperine level is the most vital parameter to show pepper quality. However, a more comprehensive result that compares the conventional and non-conventional methods for all kinds of pepper quality parameters still could not be obtained.

In designing the correct capacity of solar panels that will be used for any project, the designer should know the solar radiation in that area. Next, the UV index data is needed to know if that area is safe from ultraviolet (UV) radiation. Unfortunately, solar radiation and UV index data from many hydrometeorological stations are usually rare. Hence, there is a necessity to solve this scarcity. The study, using the correlation method, intends to make the connection between two sunshine parameters (solar radiation and the ultraviolet (UV) index) and three hydrometeorological parameters (air temperature, humidity, or pressure). If these variable couplings are known, we can find the data of solar radiation (or UV index) based on air temperature, humidity, or pressure, which are usually much easier to obtain than solar radiation or UV index. The results showed that the correlation between solar radiation (or UV index) and air temperature, humidity, and pressure was strong positive-linear, strong negative-linear, and no strong correlation, respectively. Because it has a positive correlation, the temperature data have a strong potential to replace solar radiation or UV index data.

“…The optical flow methods analyzed in this paper may also be used for the estimation of the water-flow velocity in rivers [17][18][19], replacing previously used particle image velocimetry (PIV) methods [20] as well as typical motion-tracking methods based on point detectors [21]. Nevertheless, in such types of video recordings, there is no ground truth data; hence, the evaluation of the obtained results may be conducted with the use of trajectory reconstruction.…”

The optimal water flow in fish breeding tanks is one of the crucial elements necessary for the well-being and proper growth of fish, such as salmon or trout. Considering the round tanks and the uneven distribution of water-flow velocity, ensuring a nearly optimal flow is an important task that may be performed using various sensors installed to monitor the water flow. Nevertheless, observing the rapid development of video analysis methods and considering the increasing availability of relatively cheap cameras, the use of video feedback has become an interesting alternative that limits the number of sensors inside the water tanks in accordance with the requirements of fish breeders. In this paper, an analysis of the use of optical flow algorithms for this purpose is performed and an estimation method based on their features is proposed. The results of the flow estimation using the proposed method are verified experimentally and compared with the measurement results obtained using the professional water-flow meter, demonstrating a high correlation, exceeding 0.9, confirming the proposed solution as a good alternative in comparison to the use of expensive sensors and meters.
