Seagrasses in Bali are distributed on coastal areas of south east Bali coastal waters of Nusa Dua, Serangan Island,Sanur Beach and beaches in Nusa Lembongan. In Bali, it has been reported that there are eight species of seagrasses. Thisresearch aimed to identify seagrass species on Lembongan Beach based on morphological characters and optimize PCRcondition for molecular analysis. This research is a preliminary research on molecular method for seagrass analysis. Seagrasssampling was conducted in Lembongan Beach (in front of Ketut’s Losmen) in Nusa Lembongan, Nusa Penida Subdistrict,Bali Province. DNA extraction method used was the method of Doyle and Doyle with modifications. Result showed thatthere are five species found in Lembongan Beach, Nusa Lembongan. These seagrass are Cymodocea rotundata, Enhalusacoroides, Halodule pinifolia, Thalassodendron ciliatum and Thalassia hemprichii. DNA extraction resulted in high size ofDNA and smear DNA. Optimation of PCR reaction of rbcL fragment was done at DNA concentration of 30 ng and 50 ng.The electrophoresisof PCR products showed that DNA concentration of 50 ng had thicker band than concentration of 30 ng.Keywords: DNA extraction, Morphology, PCR rbcL, Seagrass

In Indonesia, production of corn are used for fodder (55%), food (30%), and seed (15%). The growth of corn plants is limited by the presence of pests, weeds, and plant diseases. Curvularia sp. causing leaf spot and could decrease corn production. Use of mycorrhiza can be used as a biological agent in preventing pathogens outbreaks. Isolates of Curvularia sp. fungal was sprayed on corn seed. This research was conducted in laboratorium and green house. Corn seedlings were grown on sterile soil media (control), mycorrhizal treatments (100g of mycorrhizal + Curvularia sp., 200g of mycorrhizal + Curvularia sp., 300g of mycorrhizal + Curvularia sp.) and Curvularia sp. The observed variables were plant height, number of leaves, rate of disease progression, fresh weight and dry weight of plant canopy. The results showed that application of 100g inoculum tend to increase plant growth to 26-27% and percentage of mycorrhizal colonization to 58,66% thereof can decrease pathogen infection on plant at 28 day after planting.

ABSTACTResearch was conducted to determine the patterns of Brahmana Shiva fingerprint in Bali. The fingerprint samplesas many as 240 people, which consist of 120 men and 120 women from four generation of Brahmana Shiva in Bali. Thefingerprints were collected using a fingerprint pad then the data were analyzed using Chi–Square test, Student-t test,Dankmerijer index and Furuhata index. The result of fingerprints examination shown that there were four fingerprintspattern i.e. arch (A), loop ulnar (LU), loop radial (LR), and whorl (W) from four sub clan (Brahmana Manuaba, Kemenuh,Keniten, Mas), with different frequencies and anequal distribution from each fingers and both hands. The arch (A) patternin clan Brahmana Manuaba and Kemenuh have the same 0.83 % frequencies, while the frequencies of Keniten 1.17 % andMas 1.67 %. The frequencies of Loop ulnar (LU) pattern from clan Brahmana Mas were 42.66 %, Manuaba 36 %, Keniten39 %, and Kemenuh 34.33 %. The frequency of loop radial (LR) pattern from clan Brahmana Manuaba were 42.17 %,Keniten 41.83 %, Mas 37.83 %, and Kemenuh 29.51 %. The frequencies of whorl (W) pattern from sub clan BrahmanaKemenuh, Manuaba, Keniten, and Mas were 35.33 %, 22 %, 18 %, and 17.83 %, respectively. The result show asignificant differences between sub clan Mas and Kemenuh using Dankmerijer Index (DI). The result show a significantdifferences between sub clan Kemenuh with Mas, Keniten and Manuaba using Furuhata Index (FI). Total Ridge Countbetween men and women of Brahmana Shiva offspring showed unsignificantly diferences at level 5%. However, there wasa significant difference of Total Ridge Count from sub clan Manuaba with Mas, Kemenuh, and Keniten.Keywords : fingerprints, arch, loop, whorl, clan brahmana shiva.

Abstract. Reog is one of Indonesian art which is origin from Ponorogo, East Java. Barongan (dadak merak), the most dominant element of this art using the part of protected animals the green peafowl (Pavo muticus)’s feathers. In 2018, we do research to one green peafowl breeder and four “barongan” maker’s groups in Ponorogo District. Our research result found that to make single “barongan”, they need about 900-1200 feathers which is similar with 6-10 male green peafowl. Our data also shows that every groups produce about 20 “barongan” in every year. The only one green peafowl breeder in Ponorogo who has 12 adult male only can supply for one maker group. So, if we want to make reog ponorogo recognized as a world heritage, we need 20 green peafowl breeders which have 6-10 adult male individual.

ABSTRACT The use of traditional medicines in human therapies has been claimed to be much safer than that of synthetic medicines with many negative side effects. Pletekan plant (Ruellia tuberosa L.) has been used empirically for years as an antidiabetic as its leaves contain poly phenolic compounds with the ability to stimulate beta cells of the pancreas so that its capability to produce insulin improved. The main objective of our research was to identify active compounds contained in Ruellia tuberosa L. leaves extracted with ethanol. Fractionation of these active compounds was conducted by applying column and thin layer chromatography using Dichlorometan and Ethylacetat with a ratio of 6:3 as eluent. Each active compound resulted from fractionation was identified using GC-MS analysis. The results showed that four active compounds (Hexadecanamide, 9-Octadecenamide, (Z), Octadecenamide and 1,2-Benzenedicarboxylic acid were identified in this analysis. Keywords: Ruellia tuberosa L., identification of active compounds.

This study aims to determine the selection of plants and nutrient content of plant species selected by Timor deer (Cervus timorensis). This research was conducted in Penangkaran Bangsing, Pupuan, Tabanan, Bali. Determination of the composition of plant species of Timor deer feed (C. timorensis) using the direct method. The species of plants eaten by Timor deer are identified to the species level. The nutrient content of crude protein is determined by Semi-micro Kjeldahl technique, energy content (GE) with Bomb calorimeter, Calcium (Ca) and Phosphorus (P) content by Atomic Absorption Spectrophotometer (ASS) technique. Selection of the plant species eaten using the Ivlev selection index. The nutrient content of plant species is eaten compared to the standard nutrient content for timor deer. The results of the study were 13 species of selected plants, namely Impreata cylindrica, Pennisetum purpureum, Panicum ranusum, Axonopus compressus, Panicum muticum, Spilatnhes paniculata, Mikania micrantha, Gliricidia sepium, Calliandra sp, Hibiscus rosa-sinensis, Sechium edule, Diplazium esculentum, Pogostemon auricularia. The crude protein content ranged from 9.30 - 31.18%, GE 2.724 – 4.446 kcal / g, Ca 0.02 - 0.84%, and P 0.32 to 3.01%. The nutrient content is eaten according to nutritional standards according to Tuckwell (2003). Keywords : timor deer (Cervus timorensis), selection of plant spesies, nutrient content
