“…In the experiment using the oven dryer the optimum time of seaweed drying at 4 hours with a temperature of 650C where the moisture content obtained is 0.1608 kg water / kg RL, this indicates there is still a lot of water content in seaweed, so it takes a long time by increasing operating temperature [3]. The maximum level of dryness of this ATC product is 15% water content according to SNI 8170: 2015 Alkali treated Seaweed Chips.…”

Eucheuma cottonii seaweed contains carrageenan, which is used as an ingredient for the food and beverage industry. This must be processed first by an alkaline process and then dried to become chips known as alkaline treated cotton chips (ATC) products. The process of drying seaweed was done using an oven dryer using heat energy that can be adjusted to the drying time, temperature and number of products so that the quality of the dried products of seaweed products that have been processed into Alkaline Treated Cotton Seaweed (ATS) to be used as an advanced product becomes ATC (Alkali Treated Cotton Chips). The results of this study aim to find out the optimal value of temperature, drying time and the amount of ATS to get output from ATC in accordance with SNI 8170: 2015 standard and received by the customer. Based on the results of the study, it was found that the minimum significant drying process for moisture content was 12.10% at level 2, 1 kg weight, level 2 temperature 70 oC with level 3 drying time 400 minutes. Whereas the maximum gel strength is 910 gram / cm2 at level 1, weight 0.5 kg, level 2 temperature 70 oC with level 2 drying time 320 minutes.

“…The experimental results show conformity with the literature, which states that a considerable decrease in drying rate at the beginning of drying is due to the high-water content of taro which makes it easy to evaporate. Inversely proportional to the end of drying, namely, the water content in the material is getting less, which causes the water content to be challenging to evaporate so that the drying rate is slower [38] . Based on the results of the ANOVA, it was obtained that different times can reduce the drying rate significantly.…”

Belitung Taro (Xanthosoma sagittifolium) is a plant that can be processed into various food products. The high-water content of taro and the lack of a precise drying system made this material easy to rot. This study aims to evaluate the dehydration performance of tray dryers to reduce the water content of Belitung Taro. The independent variables used were air velocity (3-6 m/s), taro thickness (1-4 mm), and drying time (30-120 min). The results showed that the optimum drying time of taro is 30 min. The dryer airflow of 5 m/s significantly reduces the water content. The thickness of the slices positively affects the drying rate. The lowest water content was obtained in drying with a thickness of 1 mm. The ANOVA results show the effect of thickness, time, and flow rate variations on the drying rate. Three types of mathematical modeling are used to estimate moisture content: Newton, Page, and Modified Page. The Modified Page equation was preferred to detect the moisture content of the taro.From this study, the optimum condition of the tray dryer can be the best solution to dehydrate Belitung Taro effectively and efficiently.

“…The highest drying rate was obtained in the first 15 min, namely 0.4 g/min. According to Sari et al [16], the time is inversely proportional to the rate of the process. The decrease in rate is proportional to that of the water content of the material.…”

<p class="E-JOURNALAbstractBodyEnglish">Previous reports showed that there has been a continuous increase in the annual production of onion in Indonesia, and it is inversely proportional to the market price. The price drop is often caused by the high water content, which makes it easy to rot. Preservation of onions through a tray dryer is a good preservation method because it is effective and does not require much energy. Therefore, this study aims to determine the effect of variations in time, material thickness, and air velocity on the drying rate of onions. The samples were sliced to a size of 2 - 5 mm, followed by drying for 60 min using a tray dryer with different air rates between 4 - 7 m/s, and the rate of the process was observed every 15 min. The results showed that the drying time reduced the humidity in the chamber. The highest rate of 0.525 g/min was obtained at the peak air rate of 7 m/s. ANOVA results revealed that variations in time, onion thickness, and flow rate have a significant effect on increasing the drying rate of onions. This indicates that the method can be an effective and efficient solution to optimize the drying of the commodity.</p>
