Abstract
This research aims to know the utilization of gadung ( Dioscorea hispida Dennst) tuber concentrate on natural latex ( Hevea brasiliensis ) rubber coagulation. The design used in this study was completely randomized design (RAL) with 6 treatments and 4 replications consisting of control and treatment group with concentration of 20 ml, 40 ml, 60 ml, 80 ml and 100 ml. The parameters observed were latex coagulation by administering some concentrations of gadung tuber. One way Anava test with 0.05% significance level showed significant result that is F count = 53 and F table = 2,77. This shows that gadung tuber concentrate gives a very real effect on latex coagulation. Thus it can be concluded that there is the effect of gadung tuber concentrate to natural rubber latex coagulation.

Summary
60 ml 80 ml 100 ml HASIL Hasil pengukuran rata-rata koagulasi (Tabel 2) menunjukkan bahwa perlakuan dengan menggunakan cuka sintetis (P0) lebih cepat mengalami koagulasi yaitu 1,04 menit. Rata-Rata hasil perlakuan koagulasi lateks karet alam (Hevea brasiliensis). Setelah pengukuran rata-rata waktu koagulasi, langkah selanjutnya adalah menganalisis data menggunakan Anava (Analisis Varian) (Tabel 3). Hasil perhitungan dengan menggunakan Anava diperoleh bahwa Fhitung = 53 > dibandingkan dengan Fhitung 4,25
