This research aims to obtain the optimal concentration in the variations of natural dyes and examines the characteristics of the resulting rubber compound. Research and laboratory testing conducted at Balai Riset dan Standardisasi Industri Palembang and PT. Kobe Internasional Mandiri Bandung. This study used dye concentration in 5 phr and 4 (four) color variation that were Formula A: Flour mangosteen peel, Formula B: Meal turmeric, Formula C: Flour wooden cup and Formula D: Synthetic dyes as the control. Parameters observed were Hardness, Shore A (ASTM D 2240-1997), tensile strength, kg / cm 2 (ISO 37, 1994), elongation at break (%), 50 PPHM ozone resistance, 20%, 24 h, 40 ° C and total color difference. The results showed that the best treatments was formula C: Flour wooden cup with Hardness test results of 44 shore A, the voltage dropped by 129 kg / cm 2, Elongation at break of 845%, the ozone resistance of rubber compounds showed no cracks and the total color difference was 26,74.Key word : rubber compound, dyes, wooden cup, turmeric, mangosteen rind.AbstrakPenelitian ini bertujuan untuk mendapatkan konsentrasi optimal variasi bahan pewarna alami dan mengkaji karakteristik kompon karet yang dihasilkan.

Abstract

The objectives of this study were to find out the effect of temperature and long storage to the characteristic of dock pads on the basis of National Standard of Indonesia 06-3568-2006 and to obtain the aging resistance of rubber compound. The usage formula of rubber compound was treatment A3P4 (9 phr of the extract of caesalpinia sappan wood and the mixture of quartz sand silica : calcium karbonat clamshell 75:25 phr). The experimental design uses some various temperatures of 60 oC, 70 oC and 80 oC and variation of time from one day until 7 days. The tested parameters were the hardness, tensile strength and elongation at break . The result of the study showed that the obtained hardness were 65-68 shore A, tensile strength were 26-30 N/mm2 and the elongation at break were 263-496%. The variety analysis showed that the hardness gave lack significant effect, meanwhile the temperature and time gave significant effect for the tensile strength parameter as well as the interaction. Futhermore, elongation at break parameter affected significantly toward the temperature, the time and intraction between them, Activated energy (EA) of the rubber compound hardness 5,994 K.kal/mol., the tensile strength was 6,915 K.kal/mol and elongation at break was 66,775 K.kal/mol, finally the aging resistance of rubber compound for the storage temperature of 60 oC was 48,08 days.Keywords : the extract of caesalpinia sappan wood, after ageing, rubber compound, calcium karbonat clamshell, quartz sand silicaAbstrakTujuan penelitian mengetahui pengaruh suhu dan lama penyimpanan terhadap karakteristik kompon bantalan dermaga sesuai SNI 06-3568-2006 dan mendapatkan umur usang kompon karet. Formula kompon karet yang digunakan perlakuan A3P4 (9 phr ekstrak kayu secang dan campuran silika pasir kuarsa : kulit kerang = 75:25). Rancangan percobaan dengan variasi suhu 60 oC, 70 oC dan 80 oC dan variasi waktu 1 hingga 7 hari. Parameter yang di uji Kekerasan, tegangan putus dan perpanjangan putus. Hasil penelitian untuk kekerasan 65-68 shore A, tegangan putus 22-30 N/mm2 dan perpanjangan putus 263-496%. Analisa keragaman untuk kekerasan memberikan pengaruh yang tidak signifikan, untuk parameter tegangan putus perlakuan suhu dan waktu berpengaruh secara signifikan sedangkan interaksi berpengaruh signifikan. Untuk parameter perpanjangan putus berpengaruh secara signifikan terhadap suhu, waktu dan interaksi keduanya. Energi aktivasi (EA) kompon karet kekerasan 5,994 K.kal/mol, tegangan putus 6,915 K.kal/mol dan perpanjangan putus 66,775 K.kal/mol. Umur usang kompon karet untuk variasi suhu penyimpanan 60 oC memberikan waktu 48,08 hari.Kata Kunci : ekstrak kayu secang, ketahanan usang, kompon karet, kulit kerang, silika pasir kuarsa

Abstract

This research aims to determine the gelatinization profiles of pempek lenjer dough from several formulas, with comparising fish with tapioca flour treatment. During the heating occured an increase in viscosity caused by the swelling of the irreversible starch granules in the water caused by the kinetic energy of water molecules which is stronger than the attraction of starch molecules so that the water could get into the starch granules. Gelatinization profile result showed that the higher the addition of tapioca flour on the pempek dough the lower the initial gelatinization temperature (63°C), the lower the maximum viscosity (100 BU) is more compact the gel, paste stability was relatively low (41 BU) and the higher the reverse viscosity (31 BU), the development of the granules became larger, but the greater the the possibility of retrogradation.Keywords: dough, formulation, gelatinization, amilography properties, pempekAbstrakPenelitian ini bertujuan untuk mengetahui profil gelatinisasi adonan pempek lenjer dari beberapa formula, dengan perlakuan perbandingan ikan dengan tepung tapioka. Selama pemanasan terjadi peningkatan viskositas yang disebabkan oleh pembengkakan granula pati yang irreversible dalam air, karena energi kinetik molekul air lebih kuat dari daya tarik molekul pati sehingga air dapat masuk ke dalam granula pati. Hasil profil gelatinisasi menunjukkan bahwa semakin tinggi penambahan tepung tapioka pada adonan pempek maka suhu awal gelatinisasi semakin rendah (63°C), viskositas maksimum semakin rendah (100 BU) gel lebih kompak, stabilitas pasta relatif rendah (41 BU) dan viskositas balik semakin tinggi (31 BU) pengembangan granula lebih besar, tetapi kemungkinan retrogradasi semakin besar.Kata kunci: adonan, formula, gelatinisasi, sifat amilografi, pempek
