The results obtained for UV-Vis Mg (II) isoleucinedithiocarbamate at 267 nm and 486 nm indicate that electronic transitions π → π * and n→π* from CS2 and N = C = S. IR spectra at wavelengths in region 391536 cm shows that there has been coordination between Mg (II) and Sulfur (S) atoms, Nitrogen (N) and Oxygen (O) from the isoleucinedithiocarbamate ligand. Cytotoxic test of the Mg (II) isoleucinedithiocarbamate complex has IC50 = 11008.33 μg / mL.

This information can be provided by analyzing plant DNA using molecular markers which are polymorphic and generate clear and thick bands. The objective of the study was to obtain primers that could generate clear and polymorphically bands from Red wood DNA. The evaluated Red wood was from Alor, Sika, Lembata, Rote, and Timur Tengah Selatan (TTS) provenances. As many as 54 primers screened to polymorphism assay. Those primers consisted of RAPD, SSR, and chloroplast.The SSR primers were developed from Pterocarpus indicus (six primers) and Prosopis alba (12 primers). Chloroplast primers were divided into two types, four Rubisco Large Sub-unit genes (rbcL) and 12 MaturaseK genes (matK). SSR primers of P. alba were not able to amplify Red wood DNA, whereas those of P. indicus could amplify the DNA. Three of each chloroplast primers successfully amplified the DNA, yet, each primer could only amplify one to four of 12 evaluated samples. rbcL 2 generated the highest number of sample, and samples from Lembata were amplified the most. Moreover, 16 RAPD primers were able to generate DNA.","PeriodicalId":355290,"journal":{"name":"Proceedings of the 1st International Conference on Science and Technology, ICOST 2019, 2-3 May, Makassar, Indonesia","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114448990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The result showed that 3 isolates among 12 isolates showed their potency to produce antifungal. Based on their antifungal activity, 1 isolates (J10) were chosen to produce antifungal compound using fermentation method in GYE broth. Characterization of antifungal compound was carried out by using TLC, GC-MS and bioautographic test. The result of bioautography test showed that the spot from TLC of J10 isolates could inhibit C. albicans ATCC 10231 growth.

In reading the gas value, a reading and calibration process is carried out using matlab and optimizing the program made in reading the value of the amount of gas emission content in PPM (Part per Million) units.
