Spin transition exists on octahedral complexes with an intermediate ligand field, one of the ligands is 2,6-bis (pyrazol-3-yl)pyridine or 3-bpp. Spin transition complexes were intensively investigated because they are highly potential candidates for electronic materials, such as sensors, molecular switches and information storages. The iron(II) complex with 3-bpp ligand has shown SCO characteristics including different transition pattern and transition temperature which were influenced by type of the counter anions. The iron(II) complexes with different types of counter anions have exhibited SCO phenomenon, due to the effect of temperature with abrupt transition. However, the presence of hydrate water in the iron(II) complex results in the higher temperature transition. In addition of that, the transition pattern has changed from the abrupt transition into the gradual transition types. Several studies of SCO properties of the complex Fe(II)-3-bpp reported that the transition type and the temperature transition were influenced by the type of counter anion and the amount of hydrate molecules. With various transition patterns and transition temperatures, the potential of Fe(II)-bpp complexes as SCO materials is more interesting to explored. \u0000 \u0000Keywords: Iron(II) Complex, 3-bpp Ligand, Spin Crossover","PeriodicalId":17768,"journal":{"name":"Jurnal Kartika Kimia","volume":"71 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85481857","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}

Commonly membranes are made of polymer which has adequate resistance in filtration process. One type of them is polysulfone. Good physical endurance is its supremacy as material in the manufacture of membranes. Nevertheless, the hydrophobic nature of polysulfone makes membrane performance less efficient. Blending process using TiO2 can lessen the hydrophobicity of polysulfone, but still maintain membrane primacy. The blending process was carried out by the phase inversion method. Membrane physical structure was observed by SEM and XRD analysis. The pore arrangement on both membranes looks asymmetric. However, the PSF/TiO2 membrane has more systematic pore disposition. Good crystallinity was noticed on PSF/TiO2 membranes with crystal size of 27 nm whereas pure polysulfone looks more amorphous. Membrane performance can be discerned by considering various parameters after performance tests by using diesel fuel emulsion in water. Some of these parameters include flux, rejection, and total fouling after the emulsion filtration process. PSF/ TiO2 membrane flux values showed better results at 21.05 L/m2 hour. Rejection of the PSF/TiO2membrane looked better as well, spesifically 70,857%. Total fouling showed preferable result on the PSF/TiO2 membrane, which was 42.34%. The insertion of TiO2 by a composition of 10% of the total PSF used can improve membrane performance and morphology. \u0000 \u0000Keywords: Filtration, Flux, Membrane, polysulfone, TiO2","PeriodicalId":17768,"journal":{"name":"Jurnal Kartika Kimia","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83739847","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}

This disease is an accumulation from unhealthy lifestyle and for some people, they inherit T2DM from their parents. T2DM is related to mitochondria DNA (mtDNA) dysfunction due to DNA mutation. D-loop area is a control region in mtDNA, which is has a highest rate of DNA mutation. It divided into two areas, HV1 and HV2. Therefore, it need a lot of information to study T2DM genetically. There three stages in this research, D-loop DNA fragment amplification from four blood samples, namely DM01, DM02, DM03, and DM04. Sequence determination of D-loop fragment, and mutation analysis. D-loop fragment amplification given 0,9 kilobase (kb) in size. Sequence DNA determination showed only three samples were successful to be sequenced (DM02, DM03, and DM04). Alignment analysis of D-loop fragment and reference (rRCS) show three substitution mutations, there are 16189T>C occur in DM02 and DM03, 16233C>T occur in DM02, DM03, DM04.
