Abstract

This research has an objective to determine the effect of natural rubber (NR) and styrene butadiene rubber (SBR) utilization on physical properties of rubber compound in radiator packing cap as well as to produce rubber compound formula that fulfill the stated standard requirement. Rubber compound in radiator packing cap is made from a mixture of styrene butadiene rubber (SBR) and natural rubber (NR) with SBR and NR ratios of 90:10, 80:20, 70:30, 60:40 and 50:50 phr, respectively. The results showed that combination of SBR and NR additions had significant effect on hardness, tensile strength, and elongation at break. The best treatment was found in the 3rd compound formula (addition of SBR:NR = 70:30 phr) with compound characteristics covering 58 shore A of hardness, 208 kg/cm2 of tensile strength and 610% of elongation at break.Keywords : SBR, natural rubber, rubber compound of radiator packing cap, physical properties of rubber compound AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh penggunaan karet alam (NR) dan styrene butadiene rubber (SBR) terhadap sifat fisik kompon karet packing cap radiator, serta mendapatkan formula kompon karet yang memenuhi persyaratan.

Abstract

Skim milk homogenization at 7 (single stage), 71 and 176 kg/cm2(dual stage,35 kg/cm2 second stage )Was used in the manufacture of cottage cheese. Each lots of skim milk manufactured into cottage cheese was inoculated with lactic culture M37.Bulk stater of lactic culture M30 was homogenized at 0,35(single stage ),106,and 246 kg/cm2 (dual stage 35kg/cm2 second stage).the use of 4 deifferent bulk culture with 3 different skim milk treatment produced a total of 12bulk starter skim milk treatment combinations. All 12 bulk starter skim milk treatment combinations were randomized prior to their manufacture. The experiment was relicated four time to manufacture of 48 vats of cottage cheese. Either homogenization of skim milk at 71 kg/cm2(dual stage, 35kg/cm2second storage)or greater or homoginezation of bulk culture at 246kg/cm2(dual stage, 35kg/cm2second storage) reduced yield loss

Abstract

Tujuan penelitian adalah untuk menpelajari sifat fisika sol karet cetak dengan filler cangkang telur ayam. Sifat fisika yang dipelajari meliputi kekerasan, tegangan putus, ketahanan sobek dan ketahanan kikis. Penelitian dilakukan dengan 4 tahap yaitu pembuatan filler cangkang telur ayam, pembuatan sol karet cetak, pengujian sifat fisika dan penilaian secara visual. Perlakuan terdiri dari penggunaan cangkang telur ayam menggantikan filer karbon hitam meliputi perlakuan tanpa penggunaan cangkang telur ayam (A1), penggunaan filler cangkang telur ayam 15 Phr (B1), penggunaan filer cangkang telur ayam 30 Phr (C1) dan penggunaan filler cangkang telur ayam 45 Phr (D1). Hasil penelitian menunjukkan bahwa cangkang telur ayam dapat digunakan sebagai filler pada pembuatan sol karet cetak. Penggunaan filler cangkang telur ayam yang semakin meningkat menghasilkan sol karet cetak dengan kekerasan yang cenderung semakin menurun, tegangan putus yang semakin menurun, ketahanan sobek yang semakin menurun dan ketahanan kikis yang semakin meningkat. Secara fisual sol karet cetak yang dihasilkan dari filler cangkang telur ayam menghasilkan sol karet cetak yang baik (tidak cacat berupa sobek, lubang, lepuh, retak dan goresan).

Abstract

Blending of two rubbers can produce superior product properties. This study examines the process and cure characteristics of the NBR/EPDM blend. This study used several types of compatibilizer, i.e. methyl-methacrylate-butadiene-stirene (MBS), montmorillonite, and silica. Compatibilizer is used to get the homogeneous blend. NBR/EPDM compounds were done by two-roll mill. The mooney viscosity, rheology, and cure kinetics were studied with mooney viscometer and rheometer. It is known that the NBR/EPDM blends produce the compound with the process ability, curing time, and cure rate index better than NBR compound and EPDM compound separately. Montmorillonite as the compatibilizer produces compound with the process ability and cure rate index better than MBS and silica. Montmorillonite can be used as appropriate compatibilizer for the NBR/EPDM blend.

Abstract

Industrial wastes of rubber wood and gelam wood processing have not been maximally utilized and frequently create environment pollution. Liquid smoke from industrial waste of sawdust through pyrolysis has potential as coagulant for rubber latex. This research objective was to study the utilization of liquid smoke from pyrolysis results of rubber wood (Hevea brasiliensis M) and gelam wood (Melaleuca leucadendron L) as coagulants of rubber processed material. This study used Factorial Completely Randomized Design with two treatment factors consisting of liquid wastes of rubber sawdust (0%, 5%, 10% and 15%) and gelam sawdust (0%, 5%, 10% and 15%). The observed parameters were dryrubber content (%) and thickness of air dried rubber sheet (mm). The results showed that addition of 10% concentration liquid smoke of rubber wood (K10G10) can increase the dry rubber content and produced thin rubber processed material which were shown by the highest dry rubber content of 99.79% and the least thickness of 2.03 mm.Keywords : Rubber wood, gelam wood, air dried sheet AbstrakLimbah industri pengolahan kayu karet dan kayu gelam belum dimanfaatkan secara maksimal dan sering menimbulkan pencemaran lingkungan.

Abstract

The research was intended to study the development of color during heat treatment in a model real system consisted of sucrose, sweetened condensed milk, egg and margarine. Research applied was factorialcompletely randomized design with steaming time consist of 1,2,3 and 4 hours and temperatures consist of 100oC, and 110oC as treatment with 3 replication. The changes of color was investigated by using Munsell color system consist of value/lightness, hue angle, and chroma. Browning index was measured by using the absorbance of ethanol extracts at 420 nm in 40.0 mm silica. Amino acid content was observed by using HPLC. Research showed that there were negative correlation between steaming time and temperature with lightness, hue angle, chroma, and amino acid. While for TCD, and browning index indicated positive correlation.
