“…Hasil penelitian menunjukkan adanya perbedaan yang signifikan antar koagulan lateks yang diujikan terhadap rata-rata waktu kontak dalam penggumpalan lateks (Tabel 1.). Limbah cair hasil fermentasi pulp kakao menunjukkan (Simanjuntak et al, 2012). Kecepatan penggumpalan lateks ditentukan oleh kandungan senyawa dalam koagulan lateks yang digunakan dan derajat keasaman koagulan lateks (Ali et al, 2009;Muthawali, 2016).…”

Some rubber farmers in Indonesia use un-recommended latex coagulant and it causes bad quality of rubber. The utilization of organic latex coagulants has the potential way to improve rubber quality. The aim of this study was to determine the effect of pineapple exocarp extract, gadung tuber extract and liquid of pulp cocoa fermentation as latex coagulants toward rubber quality. The study was using Randomized Completely Block Design with six treatments and four replications the treatments tested was 10 ml and 20 ml pineapple exocarp extract, 10 ml and 20 ml gadung extract and 10 ml and 20 ml liquid of pulp cocoa fermentation. The parameters observed were contact time, weight of rubber and rubber characteristic which are comprised of serum clarity, rubber color and rubber stinky smell produced, ash content and volatile matter compared to Standart Indonesian Rubber (SIR) 20. The result of this study showed that 20 ml latex coagulant had faster contact time than others and increased weight of the rubber. It showed that rubbers produced a bit stinky smell as well, it was better than rubbers produced by inorganic latex coagulant.

In the processing of solid rubber, such as the manufacture of crumb rubber and rubber smoke sheet, one of the most important stages is the coagulation process using coagulant. The coagulation process is instrumental in determining for quality the rubber produced. Low quality of bokar is caused by farmers using coagulant which are not recommended. Because of that, it's necessary to found the alternative coagulant that does not damage the quality and the price is relatively cheap. The purpose of this research is gets the best dosage of coconut shell liquid smoke for latex coagulation and to evaluate quality crepe rubber coagulum using coconut shell liquid smoke. The quality observed is dirt content, ash content, volatile matter, PRI, Mooney viscosity, and color index was implemented at PTPN VII, Way Berulu, Pesawaran District. The doses used were 0,1%, 1,5%, 2%, 2,5%, and 3%. The result showed that the most effective dose used in this research was 1% with quality approaching formic acid treatment. PENDAHULUANKaret sebagai komoditi ekspor dan bahan baku industri berperan strategis bagi Indonesia, baik dari segi ekonomi, sosial dan lingkungan (Boerhendhy & Amypalupy, 2016). Pengelolaan tanaman karet memiliki banyak keuntungan yang bisa didapat misalnya sebagai penambahan devisa negara, sumber pendapatan masyarakat, menambah peluang pekerjaan, dan bahkan mendorong pertumbuhan ekonomi di suatu wilayah.Dalam pengolahan karet padat, seperti pembuatan karet remah dan sit asap, salah satu tahapan yang paling penting adalah proses penggumpalan lateks menggunakan bahan penggumpal (koagulan). Proses penggumpalan ini sangat berperan dalam menentukan mutu dari karet yang dihasilkan (Vachlepi et al., 2015). Bahan penggumpal lateks yang selama ini dianjurkan adalah asam formiat. Dengan alasan harga yang relatif mahal dan ketersediaan yang sulit diperoleh, sebagian besar petani karet jarang menggunakan asam formiat dan lebih memilih menggunakan
