“…The values, however, do not follow any standard flow rate samples because there were no established standard rates due to the explicit variability of rainfall in actual conditions. In fact, some conducted rainfall calibrations were done using variable water pumps applying flow rates lower than 18ml/min [30] or a range of 24-100 ml/min [31] or as high as 200 mm -h [1]. Others would use burettes as one of its rain gauge calibration method [32].…”

This paper evaluates the measurement accuracy of the three designs of an innovative Tipping-Bucket Rain Gauge (TBRG) tip mechanism. A water-level detecting circuit is used to replace the conventional reed switch sensor, which addresses the disadvantages of the magnetic sensing method that became a factor in quantification uncertainties. The TBRG configuration designs were the bucket-feed, which detects the presence of water inside the bucket, and the bottom-feed and the center-feed, which use the tip-impact method in measuring rainfall. The constant flow method is used in the experimentation. The bucket-feed shows potential in precision rainfall measurement for having -3.84% and -2.68% accuracy errors at 6 mL/min and 11 mL/min respectively, without correction algorithm applied. The tip-impact application for the bottom-feed and the center-feed resulted in a higher error percentage from the volumetric flow samples. The result indicates that actual detection in the bucket brings more measurement accuracy than the tip-counting technique.

“…Usually, 5 minutes of soaking in boiling water is sufficient. The soaking should be equipped with water balance instrumentation [30] and water surface velocity [31], [32]. The water balance instrumentation can be used to save water utilization for the soaking process.…”

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.

“…Besides air temperature, other methods may have the potential to substitute solar radiation data. Data from water balance instrumentation [42], especially from evaporation or transpiration data, might also be tried. Another idea is the utilization of cameras.…”

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.
