Despite an early description, the rhacophorid frog (Chiromantis vittiger (Boulenger 1897)) is relatively poorly known species. It has been found in several areas in the mountainous part of western Java, one of which is in the Chevron Geothermal Indonesia (CGI) concession area within Mount Halimun-Salak National Park. An ecological study of this species and its habitat was conducted in CGI from April to September 2008. The biological and ecological aspects of this tree frog such as morphology, habitat characteristics, breeding behaviour, and larval development are presented in this paper. This study found that the fertilised eggs hatch as free-swimming tadpoles. In addition, the availability of artificial habitat in the form of concrete ponds helps sustain the population throughout the year. We also report parental care in this species.

Human-crocodile conflicts (HCC) are problems affecting crocodile conservation. Scientific publications on crocodile attack cases in Indonesia are few with low validation which hinder optimal conflict mitigation efforts. The estuarine river of Kutai National Park is a natural habitat for saltwater crocodiles and mostly nearby dense settlements. This study aims to map the distribution of saltwater crocodiles and potential conflicts in the Kutai National Park area. To predict the distribution of saltwater crocodiles, we used Maximum Entropy MAXENT with its environmental predictors i.e. slope, altitude, distance from shore, distance from river, temperature, and habitat types (mangrove forest, freshwater swamp, and shrubs). MAXENT prediction showed that elevation was the most influential variable with AUC (Average Under Curve) value of 0.952. Settlements with activities occurring within one kilometer from the river and those adjacent to coastal areas proved to be the highest in human conflicts with crocodiles. Key words: conflict, crocodile, human, MAXENT

POTENSI KODOK BUDUK (Duttaphrynus melanostictus Schneider 1799) SEBAGAI PENGENDALI ALAMI HAMA DI DAERAH URBAN: The Potential of Asian Toad (Duttaphrynus melanostictus Schneider 1799 ) As Natural Enemy For Pest in Urban Area Suci Ninda Utari; Mirza Dikari Kusrini; Noor Farikhah Haneda

Kodok buduk (Duttaphrynus melanostictus) merupakan jenis kodok yang umum dijumpai di perkotaan dan keberadaannya sering diabaikan. Tujuan penelitian adalah menganalisis pemilihan pakan dari kodok buduk di habitat alamnya, kelimpahan pakan, lebar relung dan tumpang tindih relung serta mengetahui potensi kodok ini sebagai pengendali serangga hama. Analisis dilakukan pada 100 spesimen kodok buduk (50 jantan dan 50 betina) dari sekitar kampus IPB Darmaga, Bogor dengan cara pembedahan. Frekuensi pakan tertinggi di lambung jantan maupun betina kodok buduk adalah Ordo Hymenoptera, Coleoptera, Blattaria, Diplopoda, dan Isoptera. Dari segi volume, pakan tertinggi adalah Blattaria, Coleoptera, dan Scolopendromorpha, namun berdasarkan densitas relatif pakan di lambung didominasi oleh Isoptera, Hymenoptera dan Coleoptera. Ordo-ordo yang disebut di atas termasuk hama yang merugikan manusia seperti kecoak dan rayap. Tidak terdapat korelasi antara ukuran tubuh dengan volume pakan, karena terdapat bias pada data spesimen yang diambil yakni dengan ukuran tubuh 60-90 mm atau ukuran dewasa. D. melanostictus adalah satwa oportunis, namun pemilihan pakan cenderung pada jenis tertentu saja sehingga menyebabkan rendahnya nilai relung. Jantan dan betina mempunyai komposisi pakan yang sama, sehingga tumpang tindih relung menjadi tinggi. Secara umum, kodok buduk penting sebagai predator hama di daerah perkotaan. Kata kunci: analisis kodok, kebiasaan pakan, musuh alami, sumberdaya pakan

Rawa Aopa Watumohai National Park (105.194 ha) in Southeast Sulawesi is one of the important conservation areas in Wallacea. This study aimed to measure the diversity of herpetofauna, relative abundance and community similarity in four different habitats. Survey were conducted in January-April 2018 using Visual Encounter Survey (VES) based on time and transects in savanna, riparian, lowland forest, and mangrove. Forty-two species from 17 families were found consisting of 10 species of amphibians and 32 species of reptiles, in which 9 species are endemic i.e. Papurana celebensis and Draco beccarii. The highest diversity (H’) and evenness (E) indexes was found in lowland forest (H’ = 2.497, E = 0.555). The most abundant amphibian was Limnonectes modestus with 85 individuals (23.8%), while the most abundant reptile was Crocodylus porosus with 24 individuals (6.7%). The similarity of communities between the four habitats was low (<0.5), indicating that most species are specialists on particular habitats. Although diversity was relatively low in Rawa Aopa Watumohai National Park, high endemism warrants ongoing efforts to conserve amphibians and reptiles in this national park. Key words: herpetofauna diversity, Indonesia, lowland forest, national park, Sulawesi

Painted Terrapin (Batagur borneoensis Schlegel and Muller 1845) conservation in the coastal area of Aceh Tamiang Regency faces difficulties because it involves many stakeholder. The objective of this study were to analyze stakeholder interest, influences and describe the relationship among stakeholder in the conservation of Batagur borneoensis at Aceh Tamiang District. The study was conducted in Aceh Tamiang District and respondents were selected using purposive sampling method. The data obtained using questionnaire, interview, and direct observation were analyzed with stakeholder clasification matrix, stakeholder interaction matrix and descriptive analysis. The results showed that there are twenty-seven stakeholder involved in the conservation of Batagur borneoensis which can be categorized as subjects, key players, context setters, and crowds. To achieve the management objectives of Batagur borneoensis conservation, stakeholder engagement needs to be improved through collaboration among key players, participation all key stakeholder, and community empowerment. Keywords: Batagur borneoensis, collaboration, conservation, stakeholder analysis

This paper is the result of eight months research since November 1994 -June 1995, which is a part of hroaderresearch for the writer's master (S-2) thesis (on preparation). Research in three aqutic habitat (water reservoir,mangroves, and the mangrove-swamps boundary) had shown that most of the Black Cormorant population foundin the water reservoir areas. The number of the cormorant population is time fluctuated, with the highest numberfound on the 4th week of April (144 bird$). Nineteen species of water birds and 2 species of fish eating teresterialbird were found, specifically 15 species of waders, 3 species of marsh hird , 1 species of seabirds and 2 species o lfish eating terrestrial birds. 'The number of species found relatively lower than the result of research$ conducted byMulyani and Pakpahan (1993) or Oni (1995) which were done on Febuary, March, April, May and August1994.The difference occurs because less area coverage and shorter observation time ( 12 hours in a day).
