Abstract

Dragon fruit is one of the fruits with a fairly high water content which causes an increase in water activity and accelerates the growth rate of microorganisms. research was conducted to determine the shrinkage that occurs in the fruit. Two different sample sizes were used in this study. Both were cylindrical in shape with a diameter of 2.5 cm and different lengths. 3 cm (Sample A) and 1.5 cm (Sample D). The number of samples used for sample A and sample D was 5 pieces each. Measurements of weight and dimensions (sample length and diameter) were repeated every 15 minutes during the drying time at 45 ºC. Once the sample weight was constant, the material was put back into the oven at 105 ºC for 72 hours. After 72 hours, the sample was weighed and measured to determine the dry weight of the sample. Based on the study of the pattern of changes in the dimensions of red dragon fruit during the drying process, it can be concluded that the pattern of changes in volume ratio to KAbb is a linear pattern with an R2 value of 0.9946. The pattern of changes in volume ratio to KAbb is polynomial degree 2 and 3, but the R2 value is greater for degree 3, so degree 3 is more suitable for estimating the volume ratio of KAbb.values.

Abstract

The post-harvest handling of corn involves threshing, the process of separating kernels from the cob. A corn shelling machine without husking offers advantages for both sellers and buyers by allowing manual sorting of good and damaged kernels before threshing. This study evaluates the performance of a no-husk corn sheller used in the Amali District, Bone Regency. Key parameters analyzed include fuel consumption, shelling capacity, percentage of damaged kernels, and cleanliness level at three different rotational speeds (500, 600, and 700 rpm). The results indicate that increasing the rotational speed leads to higher fuel consumption and improved shelling capacity. However, the percentage of damaged kernels decreases with higher speeds, achieving an average damage rate of 0.049%. Additionally, the cleanliness level of the shelled corn reaches an average of 98%, confirming the machine’s efficiency. These findings suggest that optimizing the rotational speed enhances both productivity and output quality, making the no-husk corn sheller a viable tool for post-harvest processing.

Abstract

Coconut water (Cocos nucifera L.) is a natural beverage widely recognized for its high nutritional and health benefits. It contains essential electrolytes such as potassium, magnesium, and calcium, along with various vitamins and antioxidants; however, the quality deteriorates over time during storage. This study compares changes in the quality of young and mature coconut water stored at cold and ambient temperatures over a specific period of time. The research method includes measuring turbidity levels, pH, and total dissolved solids (TDS). The results indicate that both young and mature coconut water experience degradation in quality during storage, although at different rates. Storage at ambient temperature leads to a more rapid decline in quality than cold storage for both maturity types. Additionally, microbial growth is more frequently detected in coconut water stored at ambient temperature, particularly in mature coconut water. This study summarises that the quality of young and mature coconut water is influenced by storage temperature, with mature coconut water deteriorating at a higher rate. These findings can be recommended for storing coconut water at cold temperatures and consuming it shortly after opening it.
