Abstract

The research on the utilization of bamboo activated charcoal as a filler for sport damper has been done. This study aims to obtain the best formula of motor vehicle sport damper with bamboo activated charcoal filler and to examine the characteristics of the resulting sport damper. The design is Completely Randomized Design (RAL) non factorial, each treatment repeated three times, by treatment of B1 (activated charcoal concentration 20 phr), B2 (activated charcoal concentration 30 phr), B3 (activated charcoal concentration 40 phr ), B4 (activated charcoal concentration 50 phr) and B5 (activated charcoal concentration 60 phr). The parameters observed were characteristic of vulcanization of rubber compound sport damper, ie optimum vulcanization rate (t90), pravulcanisation time (ts2) and torsion modulus (ML and MH) and mechanical characteristics, ie tear resistance and compression set. The results showed that all treatments had a significant effect on the characteristics of vulcanization and mechanical characteristics of sport damper. The best treatment of motor vehicle sport damper obtained of B3, B4 and B5, with characteristics characteristic is fulfill of commercial sport damper.  The bamboo activated charcoal can be used as a filler for rubber products and can be used as an alternative to commercial fillers.

Abstract

The purpose of this research was to study the effect of drying conditions on the simplicia quality of java turmeric (Curcuma xanthorrhiza Roxb.) and determine the best conditions to make standardized simplicia. There are some criteria such as the conditions which can reach the standard moisture content of 10%, drying time is relatively fast, the result of dried simplicia still contains high level of curcumin, optimum shrinkage and good visual appearance. The results showed that the final moisture content can not reach 10% at the drying temperatures below 50 °C and RH above 40%. The average surface area shrinkage during the drying process crude ginger was 66.2%. There is a tendency of the lower temperatures and higher RH drying the higher levels of curcumin. Drying condition for Java turmeric recommended by this research is at a temperature of 50 °C and 30% RH.Keywords : Curcumin, drying, java turmeric, quality standardAbstrakTujuan penelitian ini adalah untuk mempelajari pengaruh kondisi proses pengeringan terhadap mutu simplisia temu lawak (Curcuma xanthorrhiza Roxb.) dan menentukan kondisi proses pengeringan terbaik untuk menghasilkan simplisia standar. Kriteria kondisi tersebut adalah yang dapat memenuhi kadar air standar 10%, waktu pengeringan yang relatif cepat, hasil pengeringannya masih mengandung kadar kurkumin yang tinggi dan penyusutan serta tampilan visual yang optimal. Hasil studi menunjukkan bahwa pada kondisi pengeringan di bawah suhu 50 oC dan RH diatas 40% kadar air akhir temu lawak tidak dapat mencapai kadar air standar. Rata-rata penyusutan luas permukaan simplisia temu lawak selama proses pengeringan adalah 66,2%. Terdapat kecenderungan semakin rendah suhu dan semakin tinggi RH pengeringan maka semakin tinggi kadar kurkumin simplisia temu lawak. Kondisi proses pengeringan simplisia temu lawak yang direkomendasikan adalah pada suhu 50 oC dan RH 30%.Kata kunci : Kurkumin, mutu, pengeringan, standar, temu lawak

Abstract

The main product of Indonesia natural rubber is SIR 20. The quality improvement can be done by converting the production of natural rubber SIR 20 to SIR 20 constant viscosity (SIR 20CV). The production of natural rubber SIR 20CV need the stabilizing agents among other a mixture of hydrazine hydrate and ammonium sulfate. The research purpose was to find out and to study the formulation and dosage of the mixture hydrazine hydrate and ammonium sulfate on the production of constant viscosity rubber. This research used factorial completely randomized design with the treatment factor consist of percentage of mixture hydrazine hydrate-ammonium sulfate (treatment A), additive dosage (treatment B) and control (HNS and blank/without additive). The treatment A consists of 50%:50% (A1), 70%:30% (A2), and 30%:70% (A3). The treatment B consists of 0.05% (B1), 0.10% (B2), 0.15% (B3) and 0.20% (B4). Parameters were latex coagulation condition, dry rubber content, and technical quality (initial plasticity/Po, plasticity retention index/PRI, Mooney viscosity/MV, stability viscosity index/SVI, volatile content and ash content). The analysis of technical quality was compared with requirements of SNI 06-1903-2000 about SIR. The results showed that the use of mixed additives of hydrazine hydrate and ammonium sulfate had a significant effect on the parameter pH of latex coagulation, dry rubber content, plasticity, Mooney viscosity, and viscosity stability index of the rubber SIR 20CV. The best treatment was obtained by the treatment of A3B1, which is 30% hydrazine hydrate and 70% ammonium sulfate with a dosage of 0.05%, because could produce natural rubber SIR 20CV with grade CV-70 in accordance with SNI 06-1903-2000.

Abstract

Research polyester yarn dyeing using disperse dyes temperature high systems have been carried out in order to get the exact coloration of polyester yarn and the yarn can be used for the manufacture of Palembang songket cloth. Coloring process is done by varying the temperature of a solution of disperse dyes respectively 110 oC, 120 oC, 130 oC and 140 oC, the coloring process each 15 minutes, 30 minutes, 45 minutes and 60 minutes. Yarn dyeing results of testing the color of old age, color fastness to washing and color fastness to rubbing. Increase the temperature of dye solution and the aging process can improve the color staining, while the color fastness to washing and color fastness to rubbing tends to remain. Optimal condition is obtained at a temperature of 130 °C dyesolution and the staining process produces aging 45 minute color (the value of K/S) 24.40, color fastness to washing each worth 5 (very good) for color change and staining, resistance color fastness to rubbing is worth 5 (very good) for the dry rub and 4.5 (good) for wet rubbing.Keywords : Songket cloth, polyester, coloring, high temperature AbstrakPenelitian pewarnaan benang poliester dengan menggunakan zat warna dispersi sistem temperatur tinggi telah dilakukan dengan tujuan untuk mendapatkan proses pewarnaan benang poliester yang tepat dan benangnya dapat digunakan untuk pembuatan kain songket Palembang.
