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.

Objectives: The goals of this research were to observe antioxidant properties from different parts of super red dragon fruit (Hylocereus costaricensis) using two antioxidant testing methods which were 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS).Methods: Antioxidant activities were determined using DPPH and ABTS assays, total phenolic content (TPC) using Folin–Ciocalteu reagent, flavonoid content by Chang’s method.Results: Inhibitory concentration 50% (IC50) of DPPH scavenging activity of all of the extracts in the range of 2.69 μg/ml was −94.17 μg/ml. The ethyl acetate peel extract of super red dragon fruit expressed the highest TPC (4.56 g GAE/100 g) and the highest total flavonoid content (12.63 g QE/100 g). TPC in flesh extract of super red dragon fruit had a negative and significant correlation with their IC50 of ABTS. The IC50 of DPPH and IC50 of ABTS of flesh extract of super red dragon fruit showed positive and significant correlation.Conclusion: All different parts extracts of super red dragon fruit (except n-hexane flesh extract) were categorized as a very strong antioxidant by DPPH method. Phenolic compounds in flesh extract of super red dragon fruit were the major contributor in antioxidant activities by ABTS method. DPPH and ABTS showed linear results in antioxidant activities of super red dragon fruit flesh extract.

AbstractDragon fruit is a cactus species which is indigenous to Americas belongs to Genus Hylocereus. Dragon fruit is commonly known as Noble woman, Pitahaya, strawberry pear, Super fruit etc. It has antioxidant properties which prevents oxidation of cholesterol. Similarly, dragon fruit contains phytonutrient, minerals and vitamins which are beneficial to blood, tissue, bone and overall health. On research it was found out that Lycopene which is responsible for red colour in dragon fruit has been linked with a lower prostate cancer risk. Nowadays it is widely used in restaurant as fruit salad, refreshing drinks, Jams, Ice creams, Jelly, fruit juice, wine etc. In Nepal, Mr. Jagannath Rai brought dragon fruit from USA in 2057 B.S. and later Gorkha Millenium multipurpose cooperatives ltd formally started cultivation of dragon fruit in commercial level from 2070 B.S (2013 A.D). In Nepal there is a wide scope for cultivation as it can cultivate in region of less rainfall at altitude of 1500 from MASL. Availability of Fallow and marginal lands of Terai, Bhitri madhes, valleys and lower range of mountain are suitable for cultivation. Moreover, there are great possibilities of production of organic dragon fruits. Inspite of various benefits and possibilities, farmers’ condition and investment are major challenges for exploration of dragon fruit in Nepal.

Utilization of Trichoderma sp fungi as pathogenic fungi antagonists in red dragon fruit plants (Hylocereus polyrhizus) in vitro. The purpose of this study was to identify foul pathogens of dragon fruit plants and then test the ability of Trichoderma sp antagonists to deciduous pathogens of red dragon fruit plants in vitro. The study was conducted from August to October 2016, The research was conducted at the Laboratory of Pest and Plant Disease Sciences, Faculty of Agriculture, Mulawarman University, Samarinda. Sampling of plants exposed to foul tendrils was carried out in Bukit Merdeka Village, Samboja District, Kutai Kartanegara Regency. There are two data observed in this study, primary data and secondary data. Primary data is data obtained directly from the source through direct field observations and laboratory observations and secondary data data obtained from interviews with farmers. The results showed that the pathogen that causes tendon rot in dragon fruit plants is the fungus Colletotrichum gloesporioides (penz. Ssaac). Trichoderma sp can inhibit the development of pathogens Colletotrichum gloesporioides (Penz.) Ssaac., With the highest average resistance of 71.85%.

Abstrak.  Suatu penelitian telah dilakukan untuk mengetahui efek agitasi susu probiotik yang ditambahkan buah naga merah (Hylocereus Polyrhizus). Penelitian ini dilakukan di Laboratorium Ilmu dan Teknologi Pengolahan Susu Fakultas Pertanian Universitas Syiah Kuala pada tanggal 29 April - 31 Mei 2016. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial 2x4 dengan 3 kali ulangan yang terdiri dari 2 faktor, A, agitasi yaitu (A1) dan (A2) non agitasi. Dan faktor B yaitu konsentrasi buah naga merah (B1) 20%,  (B2) 25%,  B3 (30%) dan (B4) 35%. Parameter yang diamati adalah derajat keasaman (pH), total mikroba dan uji organoleptik. Hasil penelitian menunujukkan bahwa terdapat pengaruh yang sangat nyata (P0,01) terhadap derajat keasaman (pH) dan berpengaruh nyata terhadap total mikroba (P0,05) serta terdapat interaksi antara kedua perlakuan. Sedangkan untuk uji organoleptik terdapat pengaruh yang sangat nyata (P0,01) terhadap kekentalan dan warna susu probiotik.  nilai derajat keasaman pH 4,03 - 4,11 dengan agitasi (pengadukan) masih sesuai dengan standar (SNI) 01-2981-1992. Sedangkan nilai total mikroba optimal terjadi pada penambahan buah naga sebanyak 30% baik agitasi maupun non agitasi. Effects of Milk Probiotic Agitation Added Red Dragon Fruit (Hylocereus Polyrhizus) on Sensory Test and Total Plate Coun Abstract.  A study about effects of milk probiotic agitation added red dragon fruit (Hylocereus Polyrhizus)  has been conducted to determine to test sensory and total plate count. This research was held at the Laboratory of Science and Milk Processing Technology, Agriculture Fakulty Syiah Kuala University on April 29 to May 31, 2016. This study used a completely randomized design (CRD) 2x4 factorial design with three replications consisting of two factors, A, agitation (A1) and (A2) non agitation. And factor B is the concentration of red dragon fruit (B1) 20%, (B2) 25%, B3 (30%) and (B4) 35%. The observed parameter is the degree of acidity (pH), total microbial and organoleptic tests. The results of the study indicate that the there is a  highly significant influence (P 0,01) to the degree of acidity (pH) and total significantly affected the total microbial (P 0.05), and there is interaction between the two treatments. As for organoleptic tests are highly significant effect (P 0.01) the thickness and color of probiotic milk. acidity pH value of 4.03 to 4.11 with agitation (stirring) is still in accordance with the standard (SNI) 01-2981-1992. While the total value of optimal microbial occurred upon addition of dragon fruit by 30% both agitation and non agitation
