Abstract

The aim of this research was to determine the properties of the PB 260 clone rubber using the Averrhoa type coagulant. The natural coagulants used in this study were Averrhoa bilimbi and Averrhoa carambola. The latex used was 150 ml of PB 260 clone rubber with a concentration of 100% natural coagulant of 75 ml and 2% formic acid. The rubber properties that were tested were Po, PRI, DRC, ash content, dirt content, volatile matter content and Mooney viscosity. This research also uses a special treatment in the form of centrifugation speed. The higher the centrifugation speed, the higher the pH value of the natural coagulant and the lower the H+ ion value, which accelerates the coagulation time of the latex. In natural coagulant extract, the highest values of Po, PRI, DRC, ash content, dirt content and Mooney viscosity were obtained at 0 rpm for Averrhoa bilimbi extract with values of 40%, 94.17%, 32.83%, 0, 32%, 0.038% and 77 MU. Meanwhile, in the test for volatile matter content, the highest value was found in Averrhoa carambola at 5000 rpm with a value of 0.23%.

Abstract

Salah satu negara yang memiliki sektor pertanian yang menghasilkan keuntungan yang cukup besar seperti ekspor komoditas pertanian karet adalah Indonesia. Tanaman karet (Hevea brasiliensis) yang menjadi salah satu produsen karet alam nomor satu di dunia, namun harga karet yang rendah menjadi permasalahan bagi petani karet. Upaya yang dapat dilakukan petani yaitu mencari alternatif koagulan alami yang dapat mempercepat penggumpalan pada lateks, salah satu jenis koagulan alami yaitu mengkudu (Morinda citrifolia L) tanaman tropis yang mengandung asam askorbat, asam asetat, asam benzoate, benzil alcohol 1-butanol, asam kaprilat, asam sekanoat, etil dekanoat, etil-ektanoat, etil benzena. Penelitian ini bertujuan untuk menentukan pengaruh dari mengkudu sebagai koagulan alami penggumpal lateks. Klon karet yang digunakan adalah klon PB 260 dengan volume koagulan 75 ml dan lateks sebanyak 150 ml, serta koagulan kimia asam formiat 2%. Pengujian yang telah dilakukan didapatkan hasil pH mengkudu lebih 3,85, waktu koagulasi 6,12 menit dan volume serum 30 mL. Mengkudu sebagai koagulan alami didapatkan hasil yang kurang bagus dibandingkan dengan koagulan kimia asam formiat
