Abstract

ABSTRACT The corelation cell specialization with IAA (indole acetic acid) content  of Catharanthus roseus cell culture by the addition of tryptophan has been done. This research is part of a strategy to increased the catharanthine content. One strategy used is the addition of tryptophan as a precursor treatment. IAA was other compound of the effect of the addition of tryptophan. Research was conducted in the laboratory using MS medium with tryptophan 50-250 mg/L. The cell morphology observations made by Halogen Nikon microscope and documented with a digital camera Nikon DXM 1200F. The results showed that cell morphology is essentially the same for each treatment. The differences seen is the presence of more the long cells in the treatment of tryptophan. The longest ratio is the treatment of 150 mg/L tryptophan at day 14 of culture. Changes in cell morphology relationship more long (run specialization) has something to do with the IAA content after treatment tryptophan. The highest IAA content equal 214,79±0,90  µg/g dw  was occurred at day 14th after being treated tryptophan 150 mg/L with 75% long cells or cells specialization. The relationship between the content of IAA specialized cells showed a positive correlation of 0.80 or 80% of each other. Key words: Cell specialization, IAA content, catharanthine, tryptophan, Catharanthus roseus ABSTRAK   Hubungan antara spesialisasi sel dengan kandungan IAA (asam indol asetat) kultur sel Catharanthus roseus dengan perlakuan triptofan telah dilakukan. Penelitian ini merupakan bagian dari strategi peningkatan kandungan katarantin. Salah satu strategi yang digunakan adalah penambahan perlakuan triptofan sebagai prekursor. IAA merupakan hasil sampingan sebagai pengaruh penambahan triptofan. Penelitian ini dilakukan di laboratorium dengan menggunakan media MS dengan triptofan 50-250 mg/L. Pengamatan spesialisasi sel dilakukan dengan mikroskop Nikon Halogen  dan didokumentasikan dengan kamera digital Nikon DXM 1200F. Bentuk sel pada dasarnya sama untuk setiap perlakuan. Perbedaan yang terlihat nyata adalah adanya sel-sel panjang lebih banyak pada perlakukan triptofan. Perlakuan yang paling panjang rationya adalah pada perlakuan 150 mg/L triptofan pada hari ke-14 kultur. Hubungan perubahan bentuk sel yang lebih banyak panjang (mengalami spesialisasi) ada hubungannya dengan kandungan IAA dan katarantin yang meningkat selelah perlakuan triptofan. Kandungan IAA paling tinggi yaitu sebesar 214,79±0,90  µg/g bk  terjadi pada hari ke 14 selelah diberi perlakuan triptofan 150 mg/L dengan persentasi sel panjang atau sel mengalami spesialisasi 75%. Hubungan antara spesialisasi sel dengan kandungan IAA menunjukkan hubungan yang positif sebesar 0,80 atau 80% saling menunjang.

Abstract

B. cereus strains were isolated from three district of North Sulawesi. The B. cereus strains are potentialindigenous bacteria for biological control agent against P. xylostella. The B. cereus strains were isolatedusing Ohba and Aizawa methods. Two hundred and two isolates putatively were isolated and identifiedas member of species B. cereus. Subseguently, representing isolates were selected to be screened forthe ability to kill P. xylostella. The screening test was conducted by using leaf depped methods with theconcentration of 1,22x108 spore/ml. The potential to kill test insect was assessed by mortality value. Theresult indicated that 10 isolates out of 15 of could produce mortality of insect from 50 to 100% afterexposure of 96 hours. It was confirmed that based on symptoms produced as well as bacterialcharacteristics reisolated from cadaver of test insect, the death of the test insects was certainly causedby application of bacterial isolates. It could be concluded that indigenous bacterial isolates identified tobe member of B. cereusare potential for biological control agent against P. xylostella. ABSTRAKUntuk memperoleh bakteri yang berpotensi sebagai agensia pengendali hayati hama Plutela.xylostelladilakukan isolasi dan karakterisasi bakteri indigenous.

Abstract

ABSTRACT Outdoor spaces are important to sustainable cities because they accommodate outdoor activities and contribute greatly to the quality of urban living.During the last decade, interest in the assessment of thermal comfort has increased because of climate changes and increased heat stress in cities. Greenspaces that provide a pleasurable thermal comfort experience for users effectively improve their quality of livability and productivity. However, current investigations lack a general framework for the use of thermal comfort assessment, such as in making master plan or designing better greenspace. This paper discusses greenspace of Sam Ratulangi University Campus relating to thermal comfort. It provides knowledge of thermal comfort investigation and landscape design review. The results of thermal comfort assessment, among 11 observed plots, only greenspace at FMIPA is categorized as comfortablespot. Greenspaces at FAPET and FEB are not really comfortable, those at BNI and FKM A and FKM B are not comfortable and those at FATEK, FAPERTA, FISIP, FH, FKM A are categorized as very uncomfortable spots. We suggest some options for redesigningof uncomfortable and very uncomfortable greenspace spots.Keywords: greenspace, outdoor, termal comfort
