Abstract

Pucuk Merah (Syzygium myrtifolium Walp.) is one of the plants belonging to the genus Syzygium family Myrtaceae. This study has been carried out to isolate and identify secondary metabolite from red leaf of Syzygium myrtifolium Walp. This research was conducted by extracting Syzygium myrtifolium Walp. leaf with Etanol followed by partition using n-Hexane, n-Hexane extact was separated by Coloum Chromatography with system isokratik. The separation of produce a compounds isolated as white powder. The result of GC-MS analysis was suggested 3 major compounds that 1-Octadecene; bis (2-ethylhexyl) hexanedioic; and bis (2-ethylhexyl) phthalate with a molecules weight in a row 252; 370 and 390.

Abstract

ABSTRACT             The research to determine “Analysis the Content of Ascorbic Acid in the Red Dragon Fruit by Iodimetri” Vitamin C concentration of postharvest red dragon fruit (Hylocereus Polyrhizus) and at the same time to recognize those the packaging could affected conten of obtained Vitamin C. Analysis process was conducted by iodimetric titration method through the sample of dragon fruit with saving period and packaging varied. The result of completed research find out there was are difference concentration of Vitamin C between packaged dragon fruit and without package, the concentration of Vitamin C in packaged dragon fruit was increase the concentration of Vitamin C from the first day (11,1680 mg/100 gram of sample) to the third day (14,8017 mg/100 gram of sample) and decrease until the fifth day (10,4743 mg/gram of sample), otherwise by another treatment without package the concentration of Vitamin C are increase from the first day (7,4928 mg/100 gram of sample) to the sixth day (19,6784 mg/100 gram of sample) and decreased until the eighth day (14,1395 mg/100 gram of sample). Keywords  : Red dragon fruit (Hylocereus Polyrhizus), Vitamin C dan iodimetric titration.

Abstract

The structure modeling of zeolite RHO with variation of Si/Al ratio (5; 4.33; 3.8; 3.36; 3; 2.69; 2.43; 2.2; 2) and variation of alkaline cations (Li+, Na+, K+, Rb+, Cs+, Fr+) calculated by the molecular mechanics method has been investigated. The result shows that the structure of zeolite RHO with Si/Al ratio 3.36 has the most stable structure with a minimum energy 2652.0308 kcal/mol. The most stable structures of zeolite RHO impregnated with cation is that impregnated with Fr+ (alkaline) with a minimum energy 3006.6587 kcal/mol. The result shows that the zeolite RHO structure with cations Fr+ (alkaline) has the largest pore diameter which potentially has the best adsorption capacity.

Abstract

Isolasi dan karakterisasi senyawa terpenoid dari fraksi etil asetat Macaranga beccariana Merr. telah dilakukan. Proses pemisahan pada fraksi etil asetat menggunakan kromatografi kolom gravitasi dengan metode elusi gradien. Isolat yang diperoleh diuji kemurniannya dengan menggunakan kromatografi lapis tipis dengan berbagai eluen yaitu n-heksana, kloroform, metanol, aseton dan etil asetat dengan nilai Rf secara berturut-turut yaitu 0; 0,75; 0,80; 0,87 dan 0,97. Senyawa terpenoid yang berhasil diisolasi berbentuk kristal putih dengan massa 0,0119 gram. Analisis dengan UV menghasilkan 1 puncak pada l 207,03 nm. Analisis senyawa dengan FT-IR mengindikasikan gugus fungsi -OH, C-H alifatik, C=C alifatik, C-O dan C=O. Berdasarkan dari hasil spektrum UV dan FT-IR maka senyawa isolat diduga mengandung senyawa terpenoid.

Abstract

The Research to determine the levels of Pb ion on swamp cabbage (Ipomoea reptans Poir) where each of media cropping given variation of leachate volume from TPA Bukit Pinang Samarinda for every 10 kg of soil has been carried out. Swamp cabbage was analyzed in the roots, stems and leaves at the age of 2 weeks to 4 weeks. The levels of Pb2+ ion was determined by dry destruction method, then measured by atomic absorption spectrophotometry. Pb2+ ion was accumulated on the ground kale plants. The highest levels of Pb2+ ion was contained in the roots of ground kale plants on media cropping which added 1.5 L of leachate at the age of 3 weeks of 2.0642 mg / kg wet weight. The lowest level of Pb2+ ion was contained in the leaves of control plants at the age of 2 weeks that was 0.0177 mg / kg wet weight.

Abstract

Synthesis methyl ester can be formed from kernel bintaro oil (Carberra Mangas L.) with two stages which is esterification and trans-esterification. The test result of methyl ester of bintaro kernel oil have iod value 92,82 g iod/100 gr oil, acid value 1,67 mg KOH/g oil with acid concentration 12,470% and saponification value 185.225 mg KOH/gr oil. From GC-MS analysis fatty acid dominant composition from methyl ester is methyl oleat with walue 45.86%. From HLB analysis show value 0,539. Result of analysis of FT-IR show methyl ester from bintaro kernel oil have typical absorbtion peak on wave number 17443.65 (C=O Ester).

Abstract

Isolation and identification of triterpenoid componds n-hexsane extract on 8 fraction of second stain from red leaf of Pucuk Merah (Syzygium myrtifolium Walp.) leaves has done. The leaves red Pucuk Merah has potential as bioactive ingredients of traditional medicinal plants in Indonesia. These leaves contain secondary metabolites Triterpenoid which has been tested phytochemical and bioactivity as antibacterial and antioxidant. Isolation was conducted by maceration method with ethanol, ethanol extract was partition with n-Hexane solvent. Then proceed with the separation by column chromatography isocratic. The results of the isolation process which isolates obtained second fractions 8 as white powder to 1.2 mg with Rf value of 0.625. Based on GC-MS analysis showed four major compounds contained in n-hexane fraction red Pucuk Merah leaves namely cis-6-ethyl-4a-cis, trans-8a-perhydro-trans-1-2-methoxycarbonylethyl)-trans-2,tr; phthalic acid, di (2-propylpentyl) ester; benzenesulfonanilide; and 14-?-H-Pregnan with a molecular weight of 339; 390 ; 233 and 288
