ABSTRACTCapability of Nir-Conservation Area for Preserving Jawa Lowland Endemic: CaseStudy in Kebumen District. Indonesia region is inhabited by 1.598 birds which 372 Indonesianendemic birds and 56 species of them are Jawa endemic. Amongs of jawa endemic birds, 19species are lowland occupant. Indeed the birds play important roles in ecosystem as agents ofpest population control, pollination, and seed dispersal. In lowland area of Jawa, intensivetransformation of land use exacerbated by no conservation area may threaten presence of theendemic birds. This study aims to assess caring capacity of disrupted area in low lands forpreserving endemic birds of Jawa.The study was conducted in Bedegelon river covering northern mountaneus area ofKebumen district from October-November 2007 using encounter rates methode. Survey wascarried out in three farm types: agroforestry (wanatani), intercropping agriculture area(tumpangsari) and mixed area of vegetation-settelment area (sempadan sungai).Result shows that four spesies Jawa lowland endemik birds was found in observed area.Lonchura leucogastroides and dicaeum trochileum found at all farm type, Prinia familiarisfound at intercropping agriculture area (tumpangsari). Alcedo coerulescens were observed atagroforestri area (wanatani) and mixed of vegetation-settelment area (sempadan sungai) farmtype.Key words : Jawa endemik birds, diversity, Jawa lowland, farm tipe, kebumen district

ABSTRACTStudy on the relationships between vegetation coverage and bird distribution in Moti Island,Ternate, North Moluccas. Research study on relationships between vegetation coverage andbird distribution in Moti Island, Ternate, Moluccas was conducted on May 2010. The objectiveof this research is to understand the bird species occurrence on a vegetation type as anindicator for environment quality determination in small Moti Island. Data on the occurrenceof bird species in the every vegetation type was collected and recorded using explorationmethod. The bird species were identified for the scientific name, local name, their activities,location or coordinate position and their vegetation or habitat. The data then compiled andtabulated for the spatial analyses using Ikonos image and topographic (SRTM) maps data.The data output from the spatial analyses then analyzed using Principle Component Analyses(PCA) to get the most important factors of vegetation cover types that influenced the occurrenceof the bird species. The results showed that about 34 bird species, belong to 20 families and 29genera have occurred in the Moti Island. About 13 vegetation types were recorded as naturalsites of bird species for feeding, playing and breeding grounds. Analyzing data using PCAshowed that at least 3 vegetation types have played as important sites for bird species in thisarea. The sites were mangrove, secondary forest and mixed gardens. The roles of both threeimportant vegetation types and bird species as environment quality indicators were in detaildiscussed in this paper. The discussion also includes how to develop fisherman villages inMoti Island using its own natural resources and biodiversity.Key words: Moti Island, birds distribution, vegetation coverage, spatial analyses

ABSTRACTThere are six species of cockatoos in Indonesia which are well known as exotic, smart, and they can be trainedÂ in a variety of attractions. Thus, many people want to keep those birds as pets. All of pets which have been keptÂ by community should be evaluated from various aspects before being reintroduced to their natural habitat. TheÂ examination of sex and species of illegal cocktoos play as a key role for the reintroduction programme. Theobjective of this study was to evaluate the reliability and effectivity of evaluation technique of morphometricÂ and molecular for reintroduction programme of cockatoos. We used the COI gene sequences from 68individuals of cockatoos from pet communities in and around Jakarta and four sequences from GenBank. TheÂ phylogenetic analysis used the neighbor-joining method, in which the genetic distance matrix calculations withÂ Kimura 2-parameter models that are implemented on a pairwise distance calculation in the MEGA programÂ version 6:05. The result of the genetic variation of the cockatoo species which shows intraspecific divergenceÂ was Cacatua alba (n=4)= 0%, C. galerita (Australia n=9)= 0.6%, C. galerita (Indonesia n=53)= 0.3%,Â C .goffiniana (n=3)= 0%, C. moluccensis (n=7)= 0.1%, and C. sulphurea (n=2)= 0.3%, with a range of 0-0.6%.Â The results indicate that the average of intraspecific of COI in the cockatoos community was 0.25Â±0.055%, andÂ interspecific divergences ranged from 3.1 to 11.6%. The phylogenetic tree shows the monophyletic clade ofÂ cockatoo species in Indonesia. In addition, DNA barcode analysis and molecular sexing could correct the errorÂ and doubts the result of five individual species identification and two individual sexing identification of C.galerita by morphological identification. The results of morphological examanation base on body weight, bodyÂ length and head-bill length of C. galerita triton were not significantly different (P?0,5). Finally, 19 individualsÂ C. galerita triton and two individuals P. aterrimus were reintroduced to their natural habitat.Keywords: cockatoo, barcodes DNA, reintroduction

ABSTRACTKarawang District is the largest producer of frog meat in West Java. To find out how the frog harvestingÂ impacts to the represent condition of population in the wild, on 16-27 May 2016 population survey wasÂ conducted on paddy field in East Karawang by implementing transect method with total length was 3000Â meters. The results of this transect method showed that the population of juvenile was the highest in most areasÂ of transects, followed by pre-adult population. The population of adult individuals was at the lowest and mostÂ adult male individuals were detected by the call that they make. Conditions of water supply in rice fields alsoÂ determine the conditions of juvenile and pre-adult populations; newly planted rice fields with high waterÂ availability obtained the highest population per unit area compared to the condition of paddy fields with a littleÂ water availability; but exceptions to the plowed rice fields, despite the availability of a lot of water butÂ disturbance from human activities was also high. Average density per unit area m2 for a little watery rice fieldsÂ to dry with a total length of 1500 meters transect were as follows: (1) juvenil density was 0.33 individuals/m2,Â (2) pre-adult density was 0.04 individuals/m2, (3) adult density was 0.005 individuals/m2. Average density forÂ much watery rice fields with a total length of 1200 meters transect were as follows: (1) juvenile density wasÂ 0.89 individuals/m2, (2) pre-adult density was 0.08 individuals/m2, (3) adult density was 0.01 individuals/m2.Key words: population density, Fejervarya cancrivora, paddy field, Karawang District

ABSTRACTTroides helena helena (Linnaeus, 1758) can be found in Java and Bali. The larval and adult stages of this butterfly do not produce any sound, but the pupal stage produces sound in response to a touching stimulus. Sony PCM-M10 recorder and Pettersson M500 USB Ultrasound Microphone were used to record the sound. Adobe Audition 3.0 was used to visualize the oscillogram and audiospectrogram of the sound. Beyond our expectations, the pupae produce ultra sound hisses which are composed of many impulses. A one-day-old pupa has a frequency range between 0.2-40 kHz; however of 2-days to 18-days-old has a frequency range between 0.2-150 kHz. The sound wave consist of two sound elements, i.e. the audible sound element (0.2-20 kHz) and inaudible sound element (>20-150 kHz) and the bandwidth is between 200 Hz to around 150 kHz, with the strongest spectrum energy at around 2.6 kHz, 4 kHz, 6 kHz, 9 kHz and 23 kHz and some strong spectrum energy is also visible at around 40 kHz.Key words: acoustic, behaviour, butterfly, pupa, Troides helena helena
