Abstract

Plant cultivation has been commonly practiced, particularly vegetable plants, such as eggplant, tomato and chili.However, many problems are persisted that is the pest attack. Epilachna admirabilis (Coleoptera) is one pest that commonlyattack vegetable plants. Many techniques have been applied to avoid this pest, but the result has not been in satisfantion. Thisstudy aimed to investigate the feeding preference of E. admirabilis, hence, the timing of eradication of this pests will beunderstood. This study was conducted in the Ecology Laboratory, Department of Biology, Mathematic and Natural ScienceFaculty, Udayana University on three different vegetable leaves, namely: the leaves of eggplant, tomato and chili. The resultsshowed that, based on the time of arrival and leaf consumed on each type of plant leaves, E. admirabilis chose the leaves ofeggplant and tomato first compared to chili. Epilachna admirabilis tend to consume the leaves of eggplants compared totomato, and there was no chili leaves has been consumed by this beetles.Keywords: eggplant, tomato, chili, pest, Epilachna admirabilis

Abstract

This study aims to determine the existence of a type of bird species as one of the charms ekowista "bird watching" inthe paddy fields Subak Latu, Abiansemal, Badung. Methodology used in this research is the method of roaming acrosslocations conducted in September and October 2015. The time observations performed in the morning (06:00 to 9:30 pm),afternoon (03:30 to 6:30 pm). The observation there are 33 types of Berung identified where six species of birds, includingprotected (L) by government regulation because it is rare and appendix, namely; brown-throated sunbird (Anthreptesmalacensis), birds honey yellow (Nectarinia jugular), cekakak Java (Halcyon cyanoventris), cekaka river (Tordirhamphuschloris), herons buffalo (Bubulcus ibis) and blekok paddy (Ardeola speciosa) and one bird species that are not protected (TL)but where is rare in Bali as well as 26 types of commonly found. Utilization of the bird as the ecotourism attraction "birdwatching" in this area is the diversity of bird species, the status of birds, bird activity and bird interactions with vegetation /habitat. Activities of interest for eco-tourism attraction is the activity of foraging, flying move, perches and nesting.Keywords: ecotourism, bird watching, bird species, activity

Abstract

Bean sprouts, vegetables that are often consumed, contain vitamin E, C, riboflavin, niacin, folate, and some minerals suchas selenium, manganese, zinc and iron. Honey contains monosaccharide i.e. fructose, sucrose, glucose, and maltose. Thisstudy aimed to investigate the effect of bean sprout extract added with honey to the spermatozoa quality of male mice and themost concentration that affected. This research used a completely randomized design (CRD). Twenty male mice divided intofour groups: control (aquadest), P1 (25 mg/g BW bean sprout extract + 0.07 ml honey), P2 (50 mg/g BW bean sprout extract+ 0.07 ml honey) and P3 (75 mg/g BW bean sprout extract + 0.07 ml honey). The extracts were given 0.3 ml/mice/day for 30days. The variables that are observed were spermatozoa motility, morphology, viability and also amount of spermatozoa. Datawere analyzed with one way ANOVA and followed by Duncan Multiple Range Test (DMRT). The results showed that beansprout extracts added with honey gave positive effects by increasing type A motility of spermatozoa but decreased type Dmotility. The treatments also increased the amount of spermatozoa significantly. However, 75 mg/g BW bean sprout extract +0.07 ml honey did not affect spermatozoa morphology and viability of male mice (Mus musculus L.). The optimal dose thataffected sperm quality in this research was 50 mg/g BW bean sprout extract + 0.07 ml honey.Keywords : honey, Mus musculus L, bean sprout extracts, the quality of spermatozoa

Abstract

Necessity of soybean in Indonesia increase every year along with population growth. The goverment need to importthe soybeans from abroad. Soybean in Indonesia are generally planted in ricefield and upland (dryland) which have potentialof deficiency water. Water deficiency can caused the reduction of soybean production. Therefore some alternatives are neededto increase the yield of soybean productivity, one of them is applying arbuscular mycorrhizal fungi (AMF). The aim of thisresearch was to know the dosage of isolates AMF to increase the growth of soybean. The experiments conducted over 2months at Agriculture Faculty’s Greenhouse, Udayana University. The research use Completely Randomized Design whichconsists of 5 treatments, which are : without inoculation/negative control (M0), 50 spores AMF (M1), 100 spores AMF (M2),150 spores AMF (M3), and ZA/positive control (M4). The results showed that, the inoculation of spores AMF Bali indigenuswere significantly different (P<0,05) on the number of leaves, leaf length, root fresh weight, and percentage of rootcolonization. The parameter of plant height, leaf width, plant fresh weight, and plant dry weight are no significant different(P>0,05) based on analysis of variance (ANOVA) level 5%. Doses 50 spores AMF (M1) is the dose of inoculants has beenable to increase number of leaves, leaf length, root fresh weight, and percentage of root colonization.Keywords : fungi mycorrhizal arbuscular, mycorrhiza doses, soybean.

Abstract

The aim of this study was to determine the of trigona species (stingless bee) live in different altitude in Bali. Samples were collected using purposive sampling technique, following earlier field observations to determine the location of the colonies. Samples were collected from three different locations, those were at Mawang and Taro Village at Gianyar Regency with the altitude of 750,87 m asl. Tua Village in Tabanan Regency with the altitude of 493,007 m asl, and Ngis Village in Karangase Regency with the altitude of 166,18 m asl, Species identifications were based on the morphological characters of nest entrance, the coloration of the body, wing venations, and the structure of bristle of hind tibia. Species identification were referred to Michener (2007), Schwarz (1939), Sakagami (1979), Sakagami and Inoue (1985), and Rassmusen and Cameron (2010). The result shows that out of 13 colonies collected from different altitude, ony 1 species was identified that was Trigona laeviceps. Keywords: Altitude, nest entrance, morphology, Trigona laeviceps

Abstract

There are many variation of Plumeria sp. that grown in Bali. The genetic identity of Plumeria sp. need to be analysedusing molecular study for plant breeding purpose. DNA extraction and primer selection are basic steps for molecular studyespecially in identification and analysis of genetic diversity. The aim of this research was to determine RAPD primerssuitable for molecular analysis of Plumeria sp. This research used CTAB method with modification for DNA extraction. Thesamples were young leaves of Plumeria sp. dried using silica gel. The primers used were produced by University of BritishColumbia and Operon Primer Technology. The results showed that DNA concentration of Plumeria sp from dried leaves wasbetween 33-267 ng/?l. Out of seven primers tested, three primers UBC-127, UBC-250, and OPH-06 produced clear andscorable amplification products for further analyses.Keywords: DNA, Plumeria sp., RAPD primer

Abstract

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
