Abstract Black grass jelly often called black jelly, also known as black cincau (“cincau” in Indonesian), was produced by boiling the black grass jelly to extract the jelly. It has a high soluble fiber content. This study investigated the analog cincau formulation using organic powder cottonii (OPC) ingredients as the gelling agent. The OPC was obtained from Seaweed Eucheuma cottonii (Lampung) without an alkali treatment. The analog cincau formulation consists of OPC, konjac, KCl, tapioca flour, cincau flavor. A commercial cincau was used as a reference. The physical quality characterization of analog cincau in this study includes gel strength, elasticity, and syneresis. Based on the physical analysis results, the best formula of analog cincau was the cincau using the following formula: OPC 65%, konjac 15%, tapioca flour 10%, and KCl 10%. Its physical characteristics were almost similar to the commercial cincau. The characteristics of the cincau with the best formula were the gel strength of 532 g/cm2, elasticity 246 (g/sec), and syneresis 2.70%.

Sangkuriang catfish (Clarias gariepinus) is one of freshwater fish which gives low gelling capacity due to its high content of sarcoplasmic protein and lipid contents. Catfish surimi was made into fish sausage with tapioca starch as filler and seaweed powder as gelling agent. Seaweed Eucheuma cottonii have ability to increase gelling properties because of its hydrocolloid content, carrageenan. In this research, different concentrations of E. cottonii seaweed powder were added to fish sausage. E. cottonii powder improved gel strength (1816.69 g.cm), WHC (88.67%) of fish sausage without giving any effect to the sensory properties of fish sausage (aroma, flavor, off-flavor, color). The best concentration of E. cottonii powder adding was 0.50%. Fish sausage added with seaweed powder (0.50%) had comparable WHC, gel properties (gel strength, biting and folding test) and sensory properties with commercial fish sausage marketed in Indonesia. Furthermore, fish sausages added by either seaweed powder had higher whiteness degree, whiter color, and higher dietary fiber content compare to commercial fish sausage.

Abstract This paper analyzes several SRAM failures using nano-probing technique. Three SRAM single bit failures with different kinds of Gox breakdown defects analyzed are gross function single bit failure, data retention single bit failure, and special data retention single bit failure. The electrical characteristics of discrete 6T-SRAM cells with soft breakdown are discussed and correlated to evidences obtained from physical analysis. The paper also verifies many previously published simulation data. It utilizes a 6T-SRAM vehicle consisting of a large number of SRAM cells fabricated by deep sub-micron, dual gate, and copper metallization processes. The data obtained from this paper indicates that Gox breakdown location within NMOS pull-down device has larger a impact on SRAM stability than magnitude of gate leakage current, which agrees with previously published simulation data.

Makalah ini menganalisis pengaruh perlakukan alkali dan tanpa perlakukan alkali terhadap karakateristik fisik, morfologi dan sifat mekanik serat kulit buah pinang (areca Catechu L.). Selama ini pemanfaatan limbah pertanian belum dilakukan secara maksimal, sehingga dapat menimbulkan pencemaran terhadap lingkungan. Serat kulit buah pinang (Areca Husk Fiber/AHF) selama ini hanya dipergunakan sebagai bahan bakar biomassa dan media tanam sedangkan untuk pemanfaatan lain belum ada sama sekali. AHF diberi perlakukan NaOH 2,5%, 5%, 7,5% dan 10% dengan waktu perendaman 2 jam pada temperatur kamar, untuk mengetahui karakteristik fisik AHF maka dilakukan pengukuran panjang dan diameter serat, pengujian densitas, pengujian kadar air dan moisture sedangkan untuk mengetahui karakteristik mekanik dilakukan pengujian tarik serat tunggal sesuai dengan ASTM D 3379. Dari penelitian ini diketahui bahwa diameter AHF mengalami pengurangan diameter akibat perlakukan alkali, hal ini terkait dengan hilangnya kandungan lignin, pektin dan wax. Densitas AHF menurun dengan meningkatan prosentase NaOH bila dibandingkan dengan AHF tanpa perlakukan NaOH. Kekuatan tarik bervariasi dengan adanya perlakuan alkali.  Kekuatan tarik AHF tertinggi pada serat yang mengalami perlakukan NaOH 5% yaitu sebesar 165 Mpa dan kekuatan tarik terendah pada AHF dengan perlakuan Alkali 10% yaitu sebesar 137 MPa .

Abstract This study aimed to prepare a niosomal gel of green tea (Camellia sinensis) extract containing catechins, mostly epigallocatechin-3-gallate (ECGC), as a potent antioxidant. Niosomes can increase EGCG's stability and penetration into the skin for a better therapeutic effect. Niosomes were prepared by a thin-layer hydration method, were evaluated for their vesicle shape, particle size, polydispersity index, zeta potential and entrapment efficiency, and then incorporated into gels using sodium alginate as a gelling agent. Three niosomal gel formulations were prepared with different concentrations of niosomes green tea extract. Afterwards, organoleptic properties, chemical and physical characteristics, antioxidant activity, and stability and irritability of the niosomal gels were investigated. The different concentrations of green tea extract had a significant effect on the physical characteristics, but not on the chemical ones. Its antioxidant activity was determined using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging method. The 50% extract green tea niosomes gel showed the highest inhibition value (25.13%). The stability was determined by freeze–thaw and real-time methods; they showed a decrease in pH, but still within the pH range of skin. The irritability test used was the Hen's Egg Test-Chorioallantoic Membrane (HET-CAM) method, which showed no irritation for all formulas. In conclusion, 50% green tea extract niosomes gel results showed it to be the best formulation with optimal antioxidant results.

ABSTRACT Alpinia galanga (L.) Sw or galangal is widely used by Indonesian people as a spice in cooking. The content of catechins and 1-acetoxicavicol acetate in the extract is known to have antioxidant activity. The ability of these antioxidants needs to be applied to pharmaceutical dosage forms to improve aesthetics and ease of use. One of the topical drug delivery systems that is in accordance with the needs of the community today is the preparation of peel-off gel mask. The purpose of this study was to determine the effect of variations in PVA gelling agent concentration as a mask base on the physical characteristics of galangal extract peel-off gel masks. Three mask formulations were made based on variations in the concentration of PVA in the range of 5% -15%. The physical characterization of the preparations included organoleptic tests, homogeneity, pH, viscosity, adhesion, dispersion, and drying time. Homogeneity and organoleptic parameters were analyzed descriptively. The parameters of viscosity, drying time, pH, spreadability, and adhesion were analyzed statistically using Anova Single Factor with a confidence level of 95%. The results showed that the F1 and F2 formulas with PVA concentrations of 10% and 12.5% were the optimum formulas as a mask base. Based on statistical tests, variations in the concentration of PVA significantly influence the parameters of mask adhesion with a p-value of 0.0001 (
