ABSTRACTSuryanto et al., 2011. Effect of callamansi citrus (Citrus microcarpa ) on chemical composition and antioxidantphytochemical of Goroho (Musa spp.) banana flour.The objective of this research was to study chemical composition and measured antioxidant activity of gorohobanana flour which immersed with callamansi. The goroho banana was soaked with water, callamansi andsodium methabisulfit for 60 minute. Furthermore, each flour were analyzed its phytochemical such as,proximate analysis, total phenolic content, flavonoid, condensed tannin, carotenoid, ascorbic acid, totalantioxidant using titration and spectrophotometer method. The results showed that callamansi addition of 1%was the best treatment for banana flour. The product had content of moisture, ash, fat, protein, fiber andcarbohydrate were 4.29 ± 0.01; 3.74 ± 0.02; 3.03 ± 2,04; 1.47 ± 0.57; 4.75 ± 0.57 and 85.70 ± 0.59,respectively. The banana flour soaked with callamansi for 60 minute had phenolic, flavonoid, condensed tannintotal content were 55.82 ± 0,01; 6.27 ± 0.08 and 36.50 ± 0.24 mg/kg, respectively. Whereas ascorbic acid andcarotenoid total content of goroho banana flour were 51.92 ± 3.73 and 6.36 ± 1.13mg /kg sample, respectively.Total antioxidant of banana flour extract soaked with callamansi shows high activity compared without soakedand soaked with sodium methabisulfit for 60 minute. The results showed that banana flour immersed withcalamansi extract and sodium metabisulfit possess different proximate composition (p<0.05). Banana immersedwith calamansi extract appears to increase phenolic, flavonoid, condensed tannin, ascorbic acid content as wellas the capacity antioxidant of banana four.Keywords : goroho banana, proximate, flour, callamansi, antioxidant phytochemical

Abstract

Petroleum waste is classified as a dangerous waste that cause pollution and damage the environtment.The remediation of petroleum polluted soil could be done by microorganism capability. Additional ofnonionic surfactant and stirring rate would make soil dispersed well in water, facilitating good contactbetween microorganism and petroleum carbon as its feed. In this research, Tween 80 and Brij 35 wereused as surfactants. The observed parameters were concentrations and stirring rates. Surfactantconcentration was selected based on surface tension value and emulsion stability. The highest emulsionstability for Tween 80 observed was 0.24% at concentration 0.0175%, while for Brij 35 equal to 0.22% atconcentration 0.0150%. Stirring rates were applied 100, 120, and 140 rpm, successively based on liquidTotal Petroleum Hydrocarbon (TPH) value. Liquid TPH value at 100, 120, and 140 rpm for Tween 80 andBrij 35 were 0.25, 0.32, 0.40 and 0.36, 0.55, 0.74%, successively. Liquid TPH depicted amount of oil thatwas dispersed into the water. The other parameters such as solid TPH and Chemical Oxygen Demand(COD) obtained for 140 rpm were 15.56% and 41235 mg/L for Tween 80 while for Brij 35 equal to 16.55%and 41717 mg/L Keywords : petroleum waste, nonionic surfactant, stirring rate

Abstract

Zubaidah Ningsih A., S. 2012. Cytolytic peptide offer a new hope in cancer treatment. Research into effective cancer treatment has not yet discovered an entirely effective and universally acceptedapproach. A promising targeted anti-cancer agent, cytolytic peptides, which can be found in plants, animals andeven human body, show high speed and selectiveness in targeting abnormal cells. Cytolytic peptides, whichcommonly are positively charged, selectively lyse the more negatively charged cancer cell membranecompared to the normal cell. In addition, the ability of cytolytic peptides to disrupt cell membrane within amillionth of a second can prohibit cancer cell resistance development. With these features, cytolytic peptidesoffer a new hope in cancer treatment.Keywords: anti-cancer, cytolytic peptide, efectivity, selectivityZubaidah Ningsih A., S. 2012. Peptida sitolitik memberikan harapan baru pada perawatan kanker. Hingga saat ini pendekatan pengobatan kanker yang efektif dan diterima secara umum belumlah ditemukan.Peptida pembunuh sel (Cytolytic peptide) yang banyak ditemukan di tanaman, hewan bahkan di tubuh manusiaditengarai mempunyai potensi menjadi obat kanker yang efektif karena efektivitas dan selektivitasnya dalammembunuh sel kanker. Peptida pembunuh sel yang umumnya bermuatan positif secara selektif dapatmenghancurkan dinding sel kanker yang bermuatan lebih negatif dibanding sel sehat. Selain itu kemampuanpeptida ini dalam menghancurkan dinding sel dalam hitungan detik mampu mencegah timbulnya resistensi selkanker terhadap obat anti-kanker. Dengan kemampuan ini peptida pembunuh sel menawarkan kemungkinan penemuan obat anti-kanker yang efektif.Kata kunci : anti-kanker, peptida pembunuh sel, efektivitas, selektivitas

ABSTRACTFatimah, F and M. Sangi, 2010. Purifying quality of virgin coconut oil using adsorbens.A Study has been carried out to know the influence of purification use some adsorben on quality of virgin coconut oil ( VCO). The adsorben where used was ash of paddy husk, active charcoal and natural zeolite. TheVCO quality measured by water and free fatty acid contents and peroxide number. The experimental result showed that the highest recovery was VCO that filtered use zeolite. Each type of adsorben gave the different influence to quality VCO. Ash of paddy husk represent the best adsorben in degrading water content (72,29 %) and free fatty acid (39,10 %), while natural zeolite represent the best adsorben in degrading number of peroxide VCO (74,549 %).Keywords : virgin coconut oil, adsorben, ash of paddy husk, active charcoal, zeolite
