Analysis of Somaclonal Variation in Cinchona succirubra Using Random Amplified Polymorphic DNA (RAPD)
Get PDFRegenerants of C. succirubra were examined by RAPD analysis to determine theoccurrence and extent of somaclonal variation. Plantlets were regenerated by nodal culture. DNAwas extracted from the parent plant and regenerants of C. succirubra. Fifteen base syntheticoligonucleotides from Operon were chosen that gave multiple polymerase chain reaction (PCR)amplification products using cinchona DNA from parent plants grown in the field and plantlets after 4and 5 passages or 4 and 5 month old in vitro culture. The results showed that all of morphologicalcharacters on regenerated plants were clonally uniform and all of the RAPD profiles were generallymonomorphic, stable, and similar to parent plants. These results demonstrated that RAPD can beused successfully to determine the somaclonal variation among regenerated plants

Aktivitas Biostatik Torosflavon D Dari Cassia Torosa Terhadap Beberapa Cendawan Patogen Tanaman
Get PDFThis research includes isolation of flavonoid Torosflavon D from Cassia Torosa, mediaformulation for pathogenic fungi growth, regeneration of pathogenic fungi, and bioactivity test of theisolated flavonoid on some pathogenic fungi. The flavonid bioactivities tests indicate that theTorosflavon D (5ppm) only effective to inhibit the radial growth of Fusarium oxysporum fsp.Lycopersici (48.75%). Statistical test (anova) indicates that concentration of the flavonid significantlyinhibit the fungi radial growth. Duncan test proves that 5 ppm concentration of Torosflavon D 5inhibits the growth of Fusarium oxysporum fsp. Lycopersici colonies optimally
Makrozoobentos Sebagai Indikator Biologi Dari Kualitas Air Di Sungai Kumpeh Dan Danau Arang-Arang Kabupaten Muaro Jambi, Jambi
Get PDFThis research is used for know the water quality in Kumpeh River and Arang-arang Lakein Kumpeh district based on macrozoobenthic as the biological indicator. To know the communitystructures of macrozoobenthic so it used the analysis of Diversity Index, which uses the Shannon –Weaner Diversity Index. Based on the result of these identification, it was found the quality ofmacrozoobenthic index diversity for Kumpeh River and Arang-arang Lake were between 1.0 - 1.5 andboth of them has been classified as the moderately polluted group. The index of macroozobenthicdiversity of Kumpeh River are about 1.21 and Arang-arang Lake about 1.19 and 1.33. The existencesof Indicator species like Chironomous sp., Scatella sp. And Branchiura sowerbyi are also indicate thatboth of water was polluted

PENGARUH KONSENTRASI STARTER Acetobacter xylinum TERHADAP KETEBALAN DAN RENDEMEN SELULOSA Nata de Soya
Get PDFSoybean wasted water is the disposed water from the process of making soybean. During these years thewater produced by soybean production is disposed to the environments, it will cause stink smell and pollutethe environments. In order to solve this problem,the wasted water can be utilized to make Nata de Soya. Natade Soya is one of the food products resulting from bactria Acetobacter xylinum. Making Nata de Soya, themost important thing should be considered carefully the starter concentration of Acetobacter xylinum given towasted water. This research is purposed to find out the effect of concentration of Acetobacter xylinum on thefermentation of soybean wasted water in making Nata de Soya. The process of fermentation is carried out onplastic plate,29 cm lenght and 24 cm width sealed with pieces of newspaper. Fermentation is done on roomtemferature and for fourteen days. The result of the research shows that starter concentration of Acetobacterxylinum influences the cellulose rendement and the thickness of Nata de soya on 15% of starter concentrationof Acetobacter xylinum that produces average thickness 1,32 cm and average sellulosa rendement 22,2 gr/L.Key word : starter concentration of Acetobacter xylinum, Sellulosa rendement,Nata de Soya
Jumlah Jenis dan Jumlah Individu Semut di Tanah Gambut Alami dan Tanah Gambut PerkebunanSawitdi Sungai Pagar, Riau Ant Diversity and Abundanceon Peat Swamp Forestand Peat Palm Oil Plantation in Sungai Pagar, Riau
Get PDFABSTRACT.   Peat lands conversion to palm oil plantation is a common phenomenon in Riau Province. The quality and fertility of peat depends on the level and depth of peat which was related to decomposition process. The objective of the research was to findout the effect of peat land conversion on antabundance anddiversity. The study was conducted on July 2012on peat swampforest and peat palm oil plantation. Ants were collected by pit fall traps method. The result showed that the number ofant specieson peat swampforest found in this study was 53 species from 316 individuals, while in the one year old palm oil plantation found 24 species from 237 individuals. Ant species diversity and abundance in peat swampforest was muchhigher thanthat on one year old palm oil plantation on peat soil. The composition and abundance of ants seem relatedto physical and chemical  properties of thepeat land, especially temperature and pH. Keywords : Ants, Peatlands, Palm oil ABSTRAK. Konversi tanah gambut menjadi kebun sawit merupakan fenomena umum di Provinsi Riau. Kualitas dan kesuburan tanah gambut tergantung pada tingkat pelapukan dan kedalaman gambut yang berkaitan dengan proses dekomposisi. Tujuan dari penelitian ini adalah untuk melihat pengaruh konversi tanah gambut terhadap jumlah jenis dan jumlah individu semut. Penelitian dilakukan pada bulan Juli 2011 pada tanah gambut alami dan tanah gambut yang sudah ditanami dengan  sawit selama satu tahun. Semut dikoleksi dengan metoda perangkap jebak (pit fall trap). Hasil yang didapatkan menunjukkan bahwa jumlah jenis dan jumlah individu semut lebih banyak didapatkan pada tanah gambut alami yaitu sebanyak 53 spesies dan 316 individu semut. Sedangkan pada tanah gambut yang sudah ditanami sawit umur satu tahun jumlah spesiesnya dan jumlah individunya lebih rendah yaitu sebanyak 24 spesies dan 237 individu. Jumlah jenis dan jumlah individu semut tergantung pada faktor fisika kimia tanah terutama temperatur dan pH. Kata kunci :semut,gambut, sawit Â
Transformasi Genetik Nicotiana benthamiana dengan Gen CP untuk Mendapatkan Ketahanan Tanaman terhadap Peanut Stripe Virus
Get PDFTransformasi genetik tanaman menggunakan Agrobacterium tumefaciens yang membawagen CP (coat protein) telah dilakukan untuk memperoleh tanamn transgenik tahan Peanut Stripe Virus(PStV). Penelitian ini bertujuan untuk mengevaluasi (1) transformasi genetik (proses rekayasagenetika) tanaman dan (2) ketahanan tanaman transgenik model (Nicotiana benthamiana) generasi T0yang membawa gen CP dan gen GUS/NPTII terhadap infeksi PStV. Hasil penelitian menunjukkanbahwa masa kritis untuk regenerasi tanaman transgenik hasil kultur jaringan adalah tahapanaklimatisasi. Tanaman transgenik N. benthamiana yang pertumbuhannya baik dengan batang lebihbesar, akar dan daun yang banyak dalam kultur in vitro, biasanya akan lebih berhasil diaklimatisasi.N. benthamiana transgenik yang membawa berbagai tipe gen CP-1, CP-2, CP-3, CP-4, dan genNPTII/GUS telah dapat dihasilkan. Sedangkan ketahanan tanaman transgenik terhadap PStV terjadiakibat integrasi gen CP dan bukan karena integrasi gen marker atau karena proses-proses lain yangdilalui dalam kegiatan transformasi tanaman dengan bantuan Agrobacterium
