Abstract

The natural occurrence of solar eclipses can cause various impact on bird species. The purpose of this study was to examine the effect of the partial solar eclipses on changes in behavior of three species of Ardeidae in the Rancabayawak, Gedebage, Bandung, West Java. The research method used was qualitative which direct observation sampling technique was applied.  The results of study showed that three bird species of Ardeidae namely Javan Pond-Heron (Ardeola speciosa Horsfield 1821), Buffalo Egret (Bubulcus ibis Linnaeus 1758, and small egrets (Egretta garzetta Linnaeus 1766) with total population 566 individuals were recorded in the resting and breeding place of bamboo trees and surrounding area of Rancabayawak during the partial solar eclipse.The behavior of these tree bird species, including sound of chicks, sunbathing, preening the feather, and flying of individual adults went out the resting and breeding place of bamboo trees observed tend to be normal before occurring the partial solar eclipse. During the partial solar eclipse, however, the sound of the chick stopped for a second. Some individual adult birds stopped involve in preening their feather. While, some adult individual birds were flying go back to the nest of bamboo trees that may be assumed it has already late afternoon due to dark of sun shine. Implication of this research have been considered to be very important for contributing the scientific knowledge on bird behavior changes caused by natural phenomena of the partial solar eclipse.

Abstract

Paper discusses result of study on the development of hobby on bird keeping, bird song contest, bird trade business, and conservation strategy for bird sustainable use, based on case study undertaken in the Bandung urban and surrounding areas. The combination of qualitative and quantitative method with descriptive analysis was used in this study. The result of study shows that based on direct inventory it was recorded 96 bird species of 24 families which were being kept by thirty respondents. Among the total species, 29 species and races were recorded as dominant, namely anis merah (Zoothera citrina), murai batu (Copsychus malabaricus), ciblek (Prinia familiaris), several races of kenari (Serinus canarinus), several races of lovebird (Agapornis spp), bentet/toed (Lanius schach), several races of pleci/burung kacamata (Zosterops palpebrosa), robin (Leothrix sp), and perkutut (Geopelia striata). Nowadays, the hobby of bird keeping in the cages has tended to increase caused of development of regular song bird contest in the local, regional and national level. Based on this study, it was recorded that fiveteen bird species have commonly entertained in the local song bird contests by the bird lovers in Bandung urban and surrounding areas. Development of the increasing bird keeping hobby and song bird contests have tended to develop bird trading in the urban bird markets and increasing bird hunting in the villages. Therefore, the activity of bird keeping hobby, song bird contests, and bird trading have been dilemma. On the one hand, these activities have provided some benefits. For example, it has developed the bird trading business and bird captive breeding undertaken by the bird lover communities and providing some economic benefits. On the other hands, these activities have affected to dramatically bird population decrease in nature due to increasing bird hunting in villages. Even some rare birds have high risk to be decrease and maybe disappear in some village areas in the near future. Therefore, to sustainable utilize bird species for fulfilling the hobby of bird keeping, bird contests and bird trading purpose; the conservation effort based on community participation is essentially needed.

Abstract

Ethnobotanical research on use of various plants for medical purposes was undertaken in Baduy area in 1994/1995 and 2004. The semi-structure interviewing with key informants and the field inventory of various medicinal plants in several land-use types of the Baduy were applied. The result of study shows that the Baduy community has intensively used various medicinal plants to cure some illnesses. However, some modern medicines have also selectively adopted by some Baduy people, particularly Outer Baduy. This is caused by intensive penetrating market economy and providing modern medicines by tourists who have come to Baduy village. The herbal medicines of the Baduy community have been mainly collected from several indigenous land use types, particularly dukuh lembur, huma, reuma and leuweung kolot.

Abstract

Kupu-kupu merupakan serangga yang mengalami metamorphosis sempurna dengan siklus hidup terdiri dari telur, ulat,pupa dan dewasa. Salah satu kupu-kupu yang banyak ditemukan di Indonesia adalah Euploea mulciber dari Family Nympalidae. Penelitian ini bertujuan untuk mengungkapkan lamanya siklus hidup kupu-kupu Euploea mulciber dari telur hingga menjadi dewasa. Metode penelitian adalah survey dan observasi dengan lokasi penelitian di wilayah pemukiman Kota Bandung. Survey dilakukan untuk mencari dan mengamati kupu-kupu yang meletakkan telurnya pada tumbuhan inang. Sedangkan observasi dilakukan untuk mengamati siklus hidup kupu-kupu (karakter morfologi dan lama siklus hidupnya). Analisis data dilakukan secara deskriptif. Pada saat survey ditemukan tiga kupu-kupu dewasa yang baru meletakkan telurnya. Telur ini, diletakkan oleh kupu-kupu pada bagian batang dan daun bagian bawah dari tumbuhan oleander (Nerium Oleander L.). Telur ini kemudian diambil dan dipelihara dalam kandang percobaan yang memiliki ratarata intensitas cahaya sekitar 26,321 Lux dan rata-rata suhu sekitar 27ᵒC. Berdasarkan hasil penelitian diketahui lamanya siklus hidup Euploea mulciber dari telur sampai menjadi dewasa adalah 25 - 27 hari dengan lama fase telur adalah 4 hari, lama fase ulat selama 15 – 16 hari dan fase pupa membutuhkan waktu selama 6-7 hari.
