Abstract

Gastropods or often called snails, live in various habitats including in rice fields habitat. There are several species of rice field gastropods which are detrimental because they damage the plants but some can be utilized. The presence of rice field gastropods is influenced by environmental factors. Environmental factors are certainly different at different altitudes, so that it might affect the species of Gastropods that exist. This study aims to determine the diversity of Gastropods found on rice fields at different altitude. Gastropod sampling were carried out in several rice fields with different altitudes, that is under 100 m, 100 m to 300 m and above 300 m to 500 m above the sea level. Sampling were done by making a 1mx1m square placed in each corner of the rice field and in the middle of the rice field. In addition to the rice fields, samples were also taken from irrigation channels that irrigated the fields. Gastropods found were six species where Lymnaea rubiginosa and Digoniostoma truncatum were only found in rice fields in each location and Terebia granifera was only found in irrigation channels. Melanoides tuberculata, Melanoides maculata and Pomacea canaliculata were found in rice fields and irrigation channels. Locations I and II have a moderate diversity index (1,360 and 1,408) and location III is low (0,795).

Abstract

The aim of the research is to analyse germination percentage, effect of coconut water addition in the media to number of last stage embryos and development of final stage D. anosmum Lindl. embryo. Research was conducted at Plant Structure and Development of Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences University of Udayana and UPT. Balai Benih Induk Tanaman Pangan dan Hortikultura Provinsi Bali from February 2015 to July 2015. Three type of media were employed, i.e. PDA, Organic, MS. Three different concentration of coconut was added to media, i.e. 0 ml/L 50 ml/L, 100 ml/L. Results showed that seed D. anosmum Lindl. on PDA, Organic and MS has not germinated yet on all media, only swollen cells observed. Seed dormancy and maturity of seed were the main factors affecting seed germination.  Addition of 100 ml / L coconut water in MS showed that media is capable to increase the formation of final stages embryos (> 32 cells). Embryo development on PDA and Organic largely showed cell stage embryos 1 to 8 cells, while MS media already showed embryo development stages of > 32 cells.

Abstract

Peranan elang brontok (Nisaetus cirrhatus) di alam adalah predator pengendali suatu ekosistem. Elang ini merupakan salah satu jenis burung pemangsa yang terancam oleh deforestasi, gangguan manusia, dan pemburuan liar, sehinga dapat menyebabkan penurunan jumlah spesies ini di alam. Akibat dari elang brontok yang ditangkap kemudian dipelihara adalah terjadinya perubahan perilaku alami ketika burung tersebut berada di kandang. Untuk pemulihan perilaku tersebut perlu dilakukan rehabilitasi, sehingga elang dapat dilepasliarkan kembali ke alam. Penelitian ini bertujuan untuk mengetahui aktivitas harian elang brontok pada masa rehabilitasi. Penelitian dilakukan di Pusat Konservasi Elang Kamojang (PKEK), Garut Jawa Barat Metode yang digunakan adalah observasi lapangan dengan menggunakan metode ad-libitum. Pada saat pengamatan elang brontok dalam kandang dicatat seluruh aktivitasnya. Pengamatan dilakukan setiap 3 hari pada tiap minggu, selama 5 minggu. Aktivitas yang diamati adalah aktivitas diam, bergerak, makan, dan lain-lain. Hasil penelitian didapatkan bahwa aktivitas diam merupakan aktivitas dengan proporsi terbesar dengan 74%, sedangkan aktivitas lain-lain sebesar 4% seperti menggerakkan ekor, mematuk kayu tempat bertenggernya, dan mengawasi mangsa merupakan aktivitas dengan proporsi terkecil pada masa rehabilitasi.

Abstract

Dalam upaya konservasi burung koak kaok (Philemon buceroides) di Taman Wisata Alam (TWA) Kerandangan yang merupakan salah satu burung yang berstatus terancam punah, maka penelitian tentang populasi dan karakteristik habitat burung tersebut sangat diperlukan. Penelitian ini menggunakan metode wawancara dan observasi. Wawancara dilakukan kepada masyarakat di sekitar TWA Kerandangan, pengunjung serta instansi yang bergerak di bidang konservasi. Responden yang diwawancarai adalah dari berbagai kelompok umur, untuk menggali informasi tentang burung koak kaok dari masa lampau hingga kini, dengan jumlah responden sebanyak 30 orang. Setelah metode wawancara, peneliti melakukan observasi di lapangan dengan menjelajahi kawasan TWAerandangan pada beberapa lokasi pengamatan yaitu Camping ground (608,82 m2), Selter 2 (613,53 m2), Selter 4 (573,11 m2) dan belakang pos (542,94 m2), dengan penjelajahan antara pukul 06.00-10.00 dan 16.00-18.00. Kapadatan populasi saat ini hanya 0,18 individu/ha yang tergolong rendah. Di sebabkan karena karakteristik habitatnya didominasi oleh pohon yang tajuknya sangat rapat sehingga burung koak kaok sulit mencari makan ataupun beraktivitas.

Abstract

Infections caused by Candida albicans have been increased dramatically worlwide. Acacia auriculiformis is an Indonesian Indigenous plant which has limited use only for fiber needs, especially for paper industry raw materials and as a protective plant. The use of Acacia auriculiformis as a traditional medicine, especially as an antifungal, is rarely reported. The purpose of this study was to determine the potential of acacia leaf extract (Acacia auriculiformis) as an antifungal against Candida albicans growth and identification of its compound class. The potential of acacia leaf extract as antifungal was tested by Kirby-Bauer method using paper discs and identification of acacia leaf compound class was carried out by phytochemical test. The results showed that acacia leaf extract (Acacia auriculiformis) concentration of 1%, 5%, 10% have potential to be an antifungal against the growth of Candida albicans and the methanol extract compound of acacia leaves consists of saponins, tannins, alkaloids, flavonoids, steroids and phenolics.

Abstract

The fungal-related diseases were responsible as one of many reasons for low production of maize in Indonesia. Controlling fungal contaminants using chemical is hazardous for human nowadays. Thus the need of environmental friendly vegetative-based fungicide such as from the extract of Ampupu tree bark is important. The objective of this study was to investigate the antifungal effect from Ampupu tree bark crude extract in response to growth of Fusarium sp, which responsible as the causal agent of corncob rot. The inhibition test on growth of Fusarium sp. by Ampupu tree bark crude extract was performed with diffusion well method on PDA as media. The process involved the infusion of crude extracts at 1.5%, 3.0% and 4.5% concentration, respectively, into diffusion well on each Petri disk. The result showed that by in vivo treatment, crude extract of Ampupu tree bark with concentration of 1.5%, 3,0% and 4.5%, were able to inhibit the fungal growth of Fusarium miniliforme as the causal agent of corncob rot with diameter of inhibition zone 0.18 mm, 1.85 mm and 2.01 mm, respectively. The higher the concentration of the crude extract given, the larger the diameter of inhibition zone formed.
