Abstract

ABSTRACT The increasing volume of garbage of Balinese Hindu’s offering is still a problem. The garbage, when it is decomposed however could be useful for fertilized. This organic litter can be decomposed in biopore. This research ainied to investigated the decomposition rate of C. nucifera and O. tigillarium litter in biopores. This research was conducted between February and July 2015. Garbage were collected from temples in Jembrana city and treated at Dangin Tukadaya village, Jembrana Distric. Sampels were arranged in a Factorial Randomized Blocked Sampling Design 2 factors i.e: treatments and times (1, 2, 3, 4 and 23 weeks). The result showed that decomposition rate 98,63% of cocos litter and 99,23% of oncosperma litter were decomposed in biopore on week 23 compared to 89,06% of cocos and 75,76 % of oncosperma litter in control. Decomposition mean rate is 9,33 %/week of cocos litter and 9,64 %/week of oncosperma litter were decomposed in biopore but in control is 7,85 %/week of cocos and 8,07 %/week of oncosperma litter. Total cocos and oncosperma litter decomposition took about 23,3 and 23,2 weeks in biopore but for control 25,8 and 30,4 weeks The number of millipedes (Harpaphe haydeniana) as decomposer was found higher compared to other decomposers such as earth worms and molusca.

Abstract

ABSTRACT Rearch on “Biodiversity of Dragonflies in Petulu Village, Ubud District, Gianyar Regency, Bali” was undertaken between May and October, 2020. Objectives of this research were to find out species and biodiversity of dragonflies of Petulu Village. Sample were collected from some research locations representing different habitats, such as rice fields, settlements, and plantations. Dragonflies which were caught or sighted on research area whould be caught by insect nests when possible and then were brought to the laboratorium at Biology Department-Fmipa Udayana University, Bali for species identification. Identification was conducted refering to some books and manuals, such as Wahyu Sigit Rhd (2013), Lilies S. (1992), etc. Data of dragonflies that were recorded including name of species and their relative abundances, and then the results were presented on a table. The status of each species (protected or not), was also provided. Shannon-Wiener diversity indexes were calculated. Results of this research showed that there were 12 species of dragonflies found, namely: Crocothemis servilia, Pantala flavescens, Orthetrum Sabina, Neurothemis terminata, Diplacodes trivialis, Potamarcha congener, Neurothemis ramburii, Orthetrum chrysis, Ischnura senegalensis, Agriocnemis femina, Agrionoptera insignis, dan Agriocnemis pygmaea. All dragonflies species found here were not protected by law. Biodiversity index (H’) of dragonflies in Petulu Village was 1.63, which indicated condition of community structure of dragonflies in Petulu Village was stable within the category of moderate. Keywords: Bali, biodiversity, dragonfly, identification, Petulu
