The Addition of Potato Biscuit in the Feed of Sumatran Slow Loris (Nycticebus coucang Boddaert, 1785) and Javan Slow Loris (Nycticebus javanicus Geoffroy, 1812): The effects on Digestibility and Feed Efficiency

This experiment aims to determine the effect of the addition of potato biscuit on digestibility and feed efficiency in Sumatran slow loris (Nycticebus coucang). Research has been conducted on Small Mammals Captivity Breeding of Zoology Division, Research Center for Biology - LIPI for 66 days consisting of a 10 days adaptation period of feed and 56 days (8 weeks) data collection period. The material used is four Sumatran slow lorises (N. coucang) and two javan slow lorises (N. javanicus). Feed given during the study are banana, papaya, dragon fruit, guava, passion fruit, boiled sweet potato, boiled egg potato biscuits, crickets, and meal worm. Feed treatment to Sumatran slow loris consisting of feed control (T0) and T0 plus potato biscuits (T1), while javan slow loris was only fed T1 as a comparison. Parameters measured were consumption, digestibility, and feed efficiency. The most palatable feed types for Sumatran slow loris and javan slow loris are banana, cricket, and meal worm. Mean of feed intake at T0 and T1 treatment was 38.63 and 37.42 g / head / day, and that of javan slow loris is 42.51 g / head / day. Mean of dry matter digestibility of javan slow loris> T1> T0, namely 92.02 persen, 91.21 persen, and 88.95 persen respectively; whereas the highest average feed efficiency (EPP) is at 12.06 persen for Sumatran Slow loris and 9.10 persen in javan slow loris. The average of total digestible nutrients (TDN) of javan slow loris> T1> T0, namely 87.04 persen, 85.34 persen, and 83.54 persen respectively.(Wartika Rosa Farida, Andri Permata Sari, Wulansih Dwi Astuti)

Kunjungan Kerja Badan Penelitian dan Pengembangan Provinsi Riau Di Pusat Penelitian Bioteknologi-LIPI

kunjungan riaua

Selasa 8 November 2016, Pusat penelitian Bioteknologi-LIPI menerima kunjungan dari Badan Penelitian dan Pengembangan Provinsi Riau. Kunjungan ini diterima langsung oleh PLH Kepala Pusat Penelitian Bioteknologi-LIPI Dr. Dwi Susilaningsih, M. Pharm yang juga menjabat sebagai kepala laboratorium Bioenergi dan Bioproses. Kunjungan kerja Balitbang prov. Riau bertujuan untuk melakukan penjajagan kerjasama dibidang penelitian mikroalga. Provinsi Riau memiliki kekayaan biodiversitas microalgae yang sangat melimpah akan tetapi belum dimanfaatkan secara optimal. Peran Pusat Penelitian Bioteknologi-LIPI sangat dibutuhkan untuk mengembangkan potensi mikroalga di Provinsi Riau sejalan dengan visi dan misi menjadi pusat studi untuk microalgae di Indonesia dan memperluas koleksi mikroalga lokal dengan berbagai keunikan dan fungsinya.

Nitrogen Fixing Potential of Endophytic Bacteria Isolated from Aloe barbadensis and Aloe sp.

Aloe is a crassulacean acid metabolism (CAM) species that are known to live in extreme environment such as drought condition. Nitrogen fixation process influenced by the ability of plants to adapt in drought condition. Endophytic bacteria from Aloe and their ability for nitrogen fixation were little reported, but potential and its relationship between the ability for nitrogen fixing with resistance to drought conditions have been not reported. This research aimed study the endophytic bacteria from two varieties of aloe, namely Aloe barbadensis Miller and Aloe sp. in their ability conducting the nitrogen fixing process and its relationship with resistance to drought. Characterization of endophytic bacteria was carried out by morphological observation of colony, Gram staining and molecular identification. Screening of nitrogen fixing was done using Nitrogen-free semisolid Nfb malate medium. Endophytic bacteria from Aloe sp. more than A. barbadensis in their potency of nitrogen fixation which related with habitat where their planted. A total of 40 persen of the endophytic isolates from the leaves of the aloe var. A. barbadensis and 62.5 persen of isolates from var. Aloe sp. are known to have a better ability to fixing nitrogen than the others. Isolates A. barbadensis AB12 and Aloe sp. AS8 were the best isolates from each variety on ability to nitrogen fixation. Based on 16S rRNA gene analysis those two selected isolates belonged to Bacillus methalotropicus strain DA 16-5 Bacillus aryabatthai strain B8 W22.
