Cocoa plant (Theobroma cacao L.) can grow well in the highlands and lowlands, a plantation and industrial plantwhich is known as one of the export commodities, as raw material for the food and pharmaceutical industries which cancontribute to an increase in foreign exchange endophytic fungus is a fungus living on a live network of plants such asseeds, leaves, flowers, twigs, stems and roots. Truffles are generally mutualistic endophyte and is known to stimulate thegrowth of plants, capable of producing antibiotics and plant growth regulators (hormones). This study aims to determinethe diversity and identify endophytic fungi on Kakao.yang found in two different locations in Bali, in the village of KajaBuahan District of Payangan, Gianyar and the Village of Tua, Marga, Tabanan regency subdistricts. Research carried outin the field with the exploration methods, isolation, identification and diversity analysis conducted at the Laboratory ofPlant Taxonomy (Mycology), Department of Biology, Faculty of Mathematics, University of Udayana.

Panglipuran Village is one of the traditional villages in Bali that still prioritizes harmonization and sense of togetherness. The village is located in Kelurahan Kubu, Kecamatan Bangli, Bangli District, Bali. Panglipuran Village has many types of plants. The varieties of plants can be influenced by several factors: one of them is introduction. This research is conducted to examine the introduction of decorative plants in Panglipuran Village, with the purpose of providing information to villagers about those plants, so that their potential can be utilized in other travel destinations, especially the ones in Bali. The method used in this research is purposive sampling. Data were obtained through direct field observation and interviews with local villagers, and later were identified at Laboratorium Taksonomi Tumbuhan FMIPA, Udayana University.

Mangosteen rind has a benefical compounds liked xanthone which consisting of mangostin, mangosterol, mangostinon A and B, trapezifolixanthone, tovophyllin B, alpha and beta mangostin, garcinon B, mangostanol, gartanin, and flavonoid epikatekin that known contain an antibacterial and antidiare agent. Escherichia coliis an opportunistic bacterium that is commonly found in the human colon as a normal flora. Its unique because it can cause primary infection in the intestine such as diarrhea in children, as well as its ability to cause infection in other body tissues outside the intestine.This research was done from December 2016 to March 2017. The methods that used in this research were well diffusion test to know the inhibitory power by measuring the clear zone formed. measure the clear zone of mangosteen rind against Escherichia coli. Then to testing extract compounds, there was used phytochemicals screening test. Data there has been found will be analyzed through analysis of variance (ANOVA). In the inhibitory test of ethanol extract from mangosteen rind (G. mangostana L.), it was so effective to inhibit the growth of Escherichia coli through in-vitro test with a resistivity of 1,58 cm and categorized as a strong inhibitory, which MIC from mangosteen rind against Escherichia coli was 3,9% and the compounds that contain in ethanol extract from mangosteen rind (G. mangostana L.) were alkaloid, phenolik, flavonoid, saponin and terpenoid. Key word : antibacterial activity, Garcinia mangostana L., Escherichia coli.

In Indonesian national economics, maize is a second food source after rice. The production of maize in some aspect is affected by the presence of insect particularly Orthopteran Order. The information of advantage and disadvantage of insects is useful for farmers. This research aimed to determine the species of Orthopteran and it is role to maize plant in the Village Kesiman, Denpasar. This research was conducted from December 2015 to February 2016. Insect was collected using sweeping net accordingly in each plot of maize plants. The plot was square form with the size of 10 m x 25 m. The sample was collected from the maize plant in the Ve phase until physiological maturation phase. in each phase, from 07.00 am until 10.00 am Bali time. Sample was collected for 15 minutes per plot and repeated three times. The insects collected was identified, and the insect density was predicted following Krebs (1989). As many as 242 individual insect which belong to Orthopteran Order was collected. Those belong to 8 families and 25 species. The species were Atractomorpha sp., Orchelimum sp., Phlaeoba sp., Gastrimargus sp., Urnisiella sp., Metaleptea brevicornis, Xenocatantops sp., Scudderia sp., Calolampra sp., Eritettix sp., Platyzoteria sp., Conocephalus strictus, Morabine sp., Acrida sp., Tenodera sp., Stagmomantis sp., Blattela sp., Periplaneta sp., Tettigidea lateralis, Mantis sp., Gryllus sp., and Anaxipha exigua, Tettigidea sp. 2, Tettigidea sp. 1, and unidentified (species x). Families that act as omnivores are Family Blattidae and Grillidae, families that act as herbivores are Pyrgomorphidae, Acrididae, Tettigonidae, Eumastacidae, and Tetrigidae, while families that act as predators are Mantidae.

ABSTRACT Long-tailed macaque (Macacafascicularis) has its name as the length of its tail as long as its body. One of their habitats is located in Pancasari Village, Sukasada, Buleleng, Bali. Its current number and their daily activity has not been scientifically studied. This research, aimed to determine the number of individuals in its age groups, and the in daily activity as. The population was calculateemploying census methodand was distinguish accordingly to different age group (a) adult, (b) juveniles and (d) infant, ceusused three times that inthe morning at 09.00-10.00, during the day at 11.00-12.00and in the afternoon at 13.00-14.00. Daily activities of this macaque were recorded withanimal focal scan sampling method, twice in a day, in the morning at 09.00-11.00 and in the afternoon at 14.00-16.00 for 7 days. The population of long-tailed macaques in this are is 252, consisting of 96 adult male, 85 adult females, 44 juveniles and 27 infants. The long tail macaques at Pancasariuse most of their time for moving (30%), followed by eating (27%)and resting (22%). Only 2% of their daily time was used for aggressive and mating.

Vanda tricolor Lindl. Var. Suavis forma Bali has a specific character than the forma Merapi and forma West Java that is size of flowers and fruits, spots purple in labellum purple colored labelum and floral fragrance. High genetic diversity is one of the major factors in breeding improvement. Increasing the diversity of orchid plant characteristics can be done by giving paclobutrazol. Treatment by paklobutrazol in culture medium aims to inhibit growth both in number of leaves and shoot length so that the plant becomes smaller size than their parent or original. The result of growth resistance that occurs varies based on the concentration of paclobutrazol added to medium Vacint & Went (VW) in culture of seeds V. tricolor orchid added with coconut water with concentration of paklobutrazol Control K0 (0%), K1 (1mg / l), K2 (3mg / l), K3 (5mg / L), and K4 (7mg / l). Each treatment performed 5 times repetition. The result of planting of Vanda tricolor seed explants with paclobutrazol modification in vitro was found 40% cultured imbibition and then protocorm, 8% browning on seed, and 52% contamination. This study showed descriptively the orchid seed Vanda tricolor responded to Vacint and Went (VW) media which was added with plant growth regulator of paklobutrazol, so that it was able to grow and develop until reaching phase 1 that seeds to form protocorm, but statistically the addition of plant growth regulator of paklobutrazol has not show a significant influence on the growth and growth response of orchids Vanda tricolor (P> 0.05) because the observation time is not sufficient for at least 6 months of observation and see the function of paklobutrazol is to slow the growth. Keywords :Vanda tricolor, paclobutrazol, in vitro, vacin went, protocorm
