[GROWTH OF DRAGON FRUIT (Hylocereus constaricensis) STEM CUTTINGS AS AFFECTED BY CONCENTRATIONS AND DIPPING TIMES OF COCONUT WATER]. Dragon fruits (Hylocereus constaricensis) is commonly propagated vegetatively by using stem cutting. In this respect the use of natural plant growth regulator, such as coconut water, to promote the growth of the cuttings is very important. The objectives of this experiment were to evaluate water coconut concentration, dipping time of stem cutting in the coconut water, and the combination of both to promote the growth of dragon fruit cuttings. The experiment was arranged in Randomized Complete Block Design (2 factors, 5 replications). The first factor was the concentration of coconut water, consisting of 5 levels: 20, 40, 60, 80, and 100%. The second factor was dipping time of cutting in the coconut water, consisting of 4 levels: 2, 4, 6, and 8 minutes. The results showed that the increasing coconut water concentration had increased the shoot growth in a liner fashion. A similar trend was also observed for coconut water dipping time. The highest shoot growth was found on 60 % coconut water.

Peel Extract

The use of colorants in the dried noodle manufactures is an effort of product diversification. Besides of being used as a natural coloring agent, this peel extract is also used to improve nutritional value of the expected product. The purpose of this study was to determine the effect of red dragon fruit peel extract on the physical quality of dried noodle.  The study was conducted by using Completely Randomized Design (CRD) method with one factor, namely concentration of red dragon fruit peel extract (N1 = 10 ml, N2 = 15 ml, N3 = 20 ml, N4 = 25 ml, N5 = 30 ml).  The observations of its physical quality consisted of water absorption, solid loss during cooking, and organoleptic tests (aroma and color).  The best quality of dried noodle was obtained by using 30 ml red dragon fruit peel extract (N5) with physical properties, namely DSA levels of 351.92%, solid loss during cooking 4.78%, aroma 3.79 (like) and color 3.89 (like).

Dragon fruit skin, waste material (dragon fruit waste), will have a profitable sale value if it can be used as a food raw material. Dragon fruit skin waste contains relatively high dietary fiber so it can be used as a food raw material. This study aims to utilize dragon fruit skin waste for the manufacture of dragon fruit skin flour as an alternative food source. Some tests are made on white-meat dragon fruit skin, red-meat dragon fruit skin and super red dragon fruit skin. The preliminary study is the soaking of the three types of dragon fruit skin in two solutions, namely 0.1% sodium citrate and 0.1% sodium metabisulfite to prevent the browning effect on flour. Dragon fruit skin flour from the soaking with both solutions is then characterized physically, including its texture, color, flavor and rendement. The best physical characterization is followed by chemical characterization, including the contents of water, ash, protein, fat, carbohydrate, dietary fiber, minerals (Fe, Na, K, Ca and P), and also microbiological characterization of Escherichia coli, molds and Bacillus cereus. The chemical and microbiological characterization shows that the red-meat dragon fruit skin flour has better results than the white-meat and super red dragon fruit skin flour does. The red-meat dragon fruit skin flour contains 8.80% water, 0.20% ash, 2.35% fat, 7.69%, protein, 68,29% carbohydrate and 28,72% dietary fiber as well as 4.40 mg K, 8.76 mg Na , 0.65 mg Fe , 10.20 mg Ca and 32.58 mg P.

Lipstick is one kind of cosmetics which is used as lips colorant to increase self-confidence. Nowadays, lipsticks from natural source is popular to reduce the negative impact of chemical compound or synthetics colorant in lipstick intensively for health. Super red dragon fruit is one kind of natural ingredients which can be used as colorant for lipstick. Moreover, this fruit is rich of antioxidant and antibacterial component that is good for skin health. In this research, extract of super red dragon fruit flesh was added in the lipstick during preparation with variation of concentration 0, 10, 20, 30 and 40%. Antioxidant analysis resulted the IC50 value in 81.55% indicating the strong antioxidant properties. Furthermore, the concentration of dragon fruit extract 40% was able to inhibit the growth of Staphylococcus aureus bacteria.

In tropical fruit crops, anthracnose is mainly caused by species belonging to the fungal genus, Colletotrichum. These phytopathogens can infect several parts of the fruit crops; however, infection during postharvest or ripening stages is responsible for major economic losses. Due to the formation of black to dark brown sunken lesions on the fruit surface, anthracnose reduces fruit quality and marketability. Among the most common tropical fruit crops susceptible to anthracnose are mango, papaya, banana, avocado, guava, and dragon fruit; these are economically relevant products in many developing countries. It is important to document that the newly recorded Colletotrichum spp. associated with fruit anthracnose can infect multiple hosts, but some species may be host-specific. By using multiple markers, many phylogenetic species of Colletotrichum have been reported as anthracnose-causing pathogens. Taking into account that disease management strategies strongly rely on adequate knowledge of the causative agents, updated information on Colletotrichum species and the hazard posed by the most recently identified species in tropical fruit plantations and harvested fruits becomes vital. Besides, the newly recorded species may be important for biosecurity and should be listed as quarantine pathogens, considering that tropical fruits are traded worldwide.
