"ABSTRACTJarak pagar (Jatropha curcasL.), salah satu tanaman sumber bahan bakar nabati tropis, telah terkenal karena ketahanannya terhadapcekaman kekeringan, akan tetapi, kemampuannya untuk tumbuh pada lingkungan yang kering masih jarang diteliti.Perubahan status air daun, kadar klorofil, suhu permukaan daun, konduktansi stomata, kadar prolin danabcisic acid (ABA), laju transpirasi dan fotosintesis dikaji pada empat genotip jarak pakar (IP-1A, IP-2M, Unggul lokal dan Daunkuning) yang diperlakukan cekaman kekeringan pada lahan pasir pantai di Jawa Tengah, Indonesia. Cekaman kekeringan menurunkan secara signifikan status air daun, kadar klorofil daun, konduktansi stomata, laju transpirasi dan fotosintesis, dan meningkatkan suhu daun, kadar prolin dan ABA. Genotip tahan (IP-1A dan IP-2M) memiliki status air daun, kadar klorofil dan laju fotosintesis lebih tinggi secara signifikan dibandingkan dengan genotip yang peka (Unggullokal dan Daun kuning). Tidak terdapat perbedaan yang nyata di ntara genotip jarak pagar terhadap suhu daun, konduktansi stomata dan laju transpirasi.

AbstractJatropha curcas L., an important tropical biofuel crop, is reputed for its drought resistance, however, its ability to perform in dry conditions has still hardly been investigated. Changes in leaf water status, chlorophyll content, leaf surface temperature, stomatal conductance, proline and abcisic acid (ABA) content, transpiration and photosyntheticrate were studied in fourJatropha genotypes (IP-1A, IP-2M, Local superior and Yellow leaf) and subjected to drought stress in coastal sandy land conditions in Central Java, Indonesia. Drought stress significantly decreased the leaf water status, leaf chlorophyll content, stomatal conductance, transpiration and photosynthetic rate, and increased leaftemperature, proline and ABA content. Resistant genotypes (IP-1A and IP-2M) had significantly higher leaf water status, chlorophyll content and photosynthetic rate than susceptible genotypes (Local superior and Yellow leaf). There were no differences between theJatropha genotypes on leaf temperature, stomatal conductance and transpiration rate."

"Telah dilakukan penelitian pada Macaca nigra di penangkaran. Penelitian dilakukan untuk mengetahui strategi adaptasi yaki yang hidup di Pusat Primata Schmutzer, Taman Margasatwa Ragunan, Jakarta melalui pengamatan perilaku makan. Penelitian pada empat individu yaki (1 jantan dan 3 betina) dilakukan selama bulan April 2013--Mei 2013 menggunakan metode scan animal sampling dan ad libitum sampling. Jumlah jam pengamatan setiap hari adalah 4 jam sehingga total pengamatan selama 20 hari adalah 80 jam. Jumlah titik sampel per harinya berjumlah 48 sampel sehingga total titik sampel selama 20 hari adalah 960 titik sampel. Tabulasi data disajikan dalam bentuk tabel dan grafik serta dianalisis secara deskriptif. Rerata aktivitas makan harian masing-masing individu menunjukkan bahwa Jenny (betina dewasa usia 8 tahun) merupakan individu dengan rerata aktivitas makan tertinggi (60.32 ± 0.08%), diikuti dengan Nonik (betina dewasa usia 14 tahun) (58.06 ± 0.11%), Rani (betina muda usia 2 tahun) (55.05 ± 0.08%), dan Ramos (jantan dewasa usia 13 tahun) (45.27 ± 0.07%). Perbedaan frekuensi aktivitas makan antara kelompok yaki di penangkaran dengan kelompok yaki di alam menunjukkan adanya strategi adaptasi tersendiri pada kelompok yaki tersebut terhadap habitatnya.

It has been done research on Macaca nigra in captivity. A study on adaptation strategies of yaki whose living in Schmutzer Primate Center, Ragunan Zoo, Jakarta through observation of feeding behavior. Research on four individuals yaki (1 male and 3 females) have been done during April 2013--May 2013 using the scan animal sampling and ad libitum sampling methods. The number of hours of observation each day is 4 hours so the total observation period of 20 days is 80 hours. Tabulation of the data presented in tables and graphs and analyzed descriptively. The mean of daily feeding activity of each individual showed that Jenny (8 years old adult female) is an individual with the highest mean feeding activity (60.32 ± 0.08%) followed by Nonik (14 years old adult female) (58.06 ± 0.11%), Rani (2 years old young female) (55.05 ± 0.08%), and Ramos (13 years old adult male) (45.27 ± 0.07%). The difference of feeding behaviour frequencies between yaki group in captivity and nature shows distinct adaptation strategy toward their habitat."

"Masyarakat beberapa negara seperti India, Pakistan dan Yunani menggunakan bunga teratai (Nelumbo nucifera Gaertn.) untuk mengobati penyakit jantung secara tradisional. Diduga bagian tanaman ini berkhasiat sebagai kardiotonik. Penggunaan obat tradisional umumnya didasarkan pada pengalaman empirik walaupun belum dibuktikan secara ilmiah. Ekstrak daun mahkota teratai telah diuji pengaruhnya terhadap gelombang T EKG dan frekuensi denyut jantung tikus putih jantan strain LMR, turunan Wistar. Pengujian ekstrak tersebut, dilakukan dengan cara menyuntikkan 1 ml larutan ekstrak tersebut secara intravena pada tikus. Kemudian efeknya dideteksi dengan elektrokardiograf, setelah 5 menit penyuntikan. Penelitian ini memberikan hasil sebagai berikut; ekstrak daun mahkota teratai meningkatkan amplitudo gelombang T EKG tikus serta meningkatkan frekuensi denyut jantungnya."

"This book shows how plants assess their surroundings, estimate their energy needs for specific goals, and communicate with each other to coordinate behavioral patterns. Coverage includes the role of viruses in these highly dynamic interactional networks."

"This rigorous yet accessible text introduces the key physical and biochemical processes involved in plant interactions with the aerial environment. It is designed to make the more numerical aspects of the subject accessible to plant and environmental science students, and will also provide a valuable reference source to practitioners and researchers in the field. The third edition of this widely recognised text has been completely revised and updated to take account of key developments in the field. Approximately half of the references are new to this edition and relevant online resources are also incorporated for the first time. The recent proliferation of molecular and genetic research on plants is related to whole plant responses, showing how these new approaches can advance our understanding of the biophysical interactions between plants and the atmosphere. Remote sensing technologies and their applications in the study of plant function are also covered in greater detail"-- Provided by publisher."
