Marshmallow belongs to a high-calorie food that requires a low-calorie substitute for sucrose, one of which is sorbitol. Marshmallow has the potential to become a functional food with the addition of inulin contained within white sweet potatoes. Inulin refers to a type of fructan carbohydrate which contains fiber and has the potential as a prebiotic that is beneficial for the human’s body. This study aims to determine the effect of the addition of white sweet potato (Ipomea batatas L.) inulin extract and sorbitol on the physical, chemical and organoleptic characteristic of marshmallows and to obtain the best marshmallow’s formula through white sweet potato (Ipomea batatas L.) inulin extract and sorbitol addition. The completely randomized design method (CRD) applied in this study consisted of one factor, namely the difference in formulation between the concentration of white sweet potato inulin extract (2% and 3%) and the concentration of sorbitol (25%, 50%, and 75%). The statistical analysis utilized the One Way Analysis of Variance (ANOVA) method using SPSS. The results of this study indicated that the addition of white sweet potato inulin extract and sorbitol had a significant effect on tensile strength, density, moisture content, ash content, total calories, dietary fiber, and organoleptic characteristics of marshmallows. The best formula for marshmallows was formula 4 with the addition of 2% white sweet potato inulin extract and 50% sorbitol.

Retnati, Andriani MAM, Fauza G. 2009. The influence of addition of various sweet potatoes (Ipomea batatas) extract to total count of cells and antioxidant activity in yogurt. Biofarmasi 7: 68-76. The aim of this research was to determine the influence of addition of various sweet potatoes extract to the total count of cells and the antioxidant activity in yogurt. Yogurt was made from fresh milk, skim milk, white sweet potato, orange sweet potato, purple sweet potato, and pure culture of Streptococcus thermophilus 0040 and Lactobacillus bulgaricus 0041 in straight MRS agar. Fresh milk, skim milk powder (5%, b/v), and sweet potato extract (10%, v/v) was pasteurized at 90oC for 15 minutes, cooled to the temperature between 40-45oC, inoculated with 2.5% S. thermophilus and L. bulgaricus with a proportion of 1.4:1, and then incubated at a temperature of 40oC for 15 hours. Yogurt without an addition of sweet potato extract was used as control. The parameters measured in this experiment were the total count of cells with TPC (Total Plate Count) method and the antioxidant activity with DPPH (2,2- diphenyl-1-picrylhydrazyl) method. Samples were taken at one hour interval to examine the total count of cells, while the antioxidant activity was collected at three hours interval. The result of each analysis was plotted into graphics which describing the relation of total bacteria and antioxidant activity with fermentation time. ANOVA was employed to analyze the data. If there was a significant difference, it should be followed by Duncan Multiple Range Test (DMRT) at a significance level α=0.05. The result of this research showed that the addition of various sweet potatoes extracts increased the total count of cells and the antioxidant activity in yogurt. The total count of cells showed no significant different for each sample, it meant that the different colors in sweet potato did not influence the total count of cells. However, yogurt with orange and purple sweet potato extract addition had a significant difference on the antioxidant activity with control and yogurt with white sweet potato extract. In conclusion, the difference colors in sweet potato influenced in the antioxidant activity in yogurt significantly. Sweet potato is potential for milk substitute in yogurt production due to oligosaccharide content and antioxidant activity.

Producing ‘Hawaiian Heritage’ cultivars can raise the market value of locally grown sweet potatoes and increase small farmer earnings in Hawaii. Twelve sweet potato breeding lines (Ipomea batatas L.), derived from the Hawaiian maternal parent ‘Mohihi’, together with four check varieties, were trialed under organic management conditions across three environments (site-year combinations) in Oahu, Hawaii (Waimānalo-2018, Waimānalo-2019 and Poamoho-2019). Trials were harvested five months after planting, consistent with local commercial production standards. There were significant differences in fresh harvest yield, post-curing yield, shape, and quality between environments and cultivars. The ‘Hawaiian Heritage’ lines HM 26 and HM 34 outperformed the commercial standard, demonstrating the potential use of traditional Hawaiian germplasm in modern breeding programs. Additionally, ‘Hawaiian Heritage’ lines (e.g., HM 32 and HM 17) with unique traits favored by the local community may be suitable breeding materials for niche markets.

In aquaculture, fish health problems are often encountered which can lead to failure in cultivation activities. One of the efforts to overcome the problem of disease in cultivation is done by providing immunostimulants. Sweet potato leaves (Ipomoea batatas) are plants that have a short harvest period, cheap and rich in vitamins and antioxidants so that it can be used as a source of immunstimulants. This research was conducted to determine the effect of adding sweet potato leaves (Ipomea batats) to tilapia (Oreochromis niloticus) feed on total leukocytes, phagocytic activity, hematocrit, and survival rate. The study was conducted by experimental method using a completely randomized design, with 4 treatment doses of sweet potato (Ipomoea batatas) used were 0%, 5%, 10% and 15%, which were formulated in fish feed and each treatment was repeated 3 times.. The results showed that giving 10% of sweet potato (Ipomea batatas) leaves in feed had a significant effect on the non-specific immune system of tilapia, which could increase the highest total leukocyte value by 6600 mm3 but did not have a significant effect on the phagocytosis index. 96.3%, 31% hematocrit with 93% survival.

Abstract Sweetpotato (Ipomea batatas), as a well-known plant and widely cultivated by farmers in South Sulawesi, if it is intercropped with satoimo taro (Colocasia esculenta (L.) Schott var. Antiquorum) as a staple crop should be suspected of being able to be a ‘safety’ crop when there is a failure in taro plant—due to the relatively new and un-well-known plant. The study was aimed to know the productivity and economic value of sweet potato planted as an intercropped on the staple crop satoimo taro plantation with several levels of compost. The study used a randomized complete block design with four levels of manure compost, namely 400 grams, 800 grams, and 1200 grams per staple plant, which put into and mixed evenly in the plant hole, and 1200 grams per staple plant which mixed evenly in the beds, and three blocks. Sweet potatoes were planted between staple plants satoimo that arranged 20 plants in a bed of 500 cm x 110 cm in two rows. The parameters observed were yields of tuber per plant, size of tuber, number of tubers, and dry weight of tops. The results showed that there is no level of compost affected significantly. However, both of the levels of 1200 grams of compost which is filled into the plant hole, and 1200 grams of compost mixed in the beds tended to be higher than the others in tuber productivity. By economic valuations, the RC-ratio and RC-ratio indicated that planting intercropped sweet potato are beneficially in all levels and increased after the levels of compost. Cultivating sweet potato intercropped in the two kinds application of 1200 grams levels in the taro plantation is more recommended.
