Pengaruh Penggumpal Bahan Organik terhadap Kualitas Lateks

Abstract

Karet (Hevea brasiliensis M.) merupakan komoditas perkebunan yang sangat penting peranannya di Indonesia. Lateks adalah cairan getah yang di dapat dari bidang sadap pohon karet. Pada umumnya berwarna putih seperti susu dan belum mengalami penggumpalan dengan atau tanpa penambahan bahan pemantap (zat anti penggumpal). Penggunaan penggumpal yang digunakan oleh petani karet banyak berasal dari bahan bahan kimia. Penggunaan penggumpal bahan kimia dapat mengurangi lateks yang dihasilkan dari pohon karet tersebut, Penelitian ini dilakukan dengan menggunakan metode kontras orthogonal yang terdiri dari 3 faktor perlakuan, yaitu : 1. Kontrol = Pemberian Asam Semut 25 ml, 2. Jenis penggumpal organik terdiri dari 4 taraf : K1 = Asam Gelugur K2 = Cairan Nenas K3 = Belimbing Wuluh K4 = Asap Cair. 3. Dosis penggumpal organik terdiri dari 2 taraf : V1 = 15 ml V2 = 30 ml. Hasil Penelitian ini menunjukkan Penggunaan Bahan penggumpal organik tidak berpengaruh nyata terhadap lama menggumpal, volume lateks, lama aliran lateks, berat basah lateks, dan berat kering lateks, tetapi berpengaruh sangat nyata terhadap kadar karet kering lateks. Pemberian dosis bahan penggumpal organik tidak berpengaruh nyata terhadap parameter lama menggumpal, lama aliran lateks, berat basah lateks dan berat kering lateks. Tetapi berpengauh nyata terhadap volume lateks dan kadar karet kering lateks. Rubber (Hevea brasiliensis M.) is a very important plantation commodity in Indonesia. Latex is a liquid sap that is obtained from the tapping of rubber trees. In general, it is white like milk and has not experienced clotting with or without the addition of a thickening agent (anti-caking agent). The use of coagulants used by rubber farmers mostly comes from chemicals. The use of chemical coagulants can reduce the latex produced from the rubber tree. This research was conducted using the orthogonal contrast method which consisted of 3 treatment factors, namely: 1. Control = Provision of Ant Acid 25 ml, 2. Types of organic coagulation consisting of 4 levels : K1 = Gelugur Acid K2 = Pineapple Liquid K3 = Belimbing Wuluh K4 = Liquid Smoke. 3. The dose of organic coagulation consists of 2 levels: V1 = 15 ml V2 = 30 ml. The results of this study indicate that the use of organic coagulant materials has no significant effect on the coagulation time, latex volume, latex flow time, latex wet weight, and latex dry weight, but has a very significant effect on latex dry rubber content. The dose of organic coagulant agent did not significantly affect the parameters of coagulation time, latex flow time, latex wet weight and latex dry weight. But it has a real effect on latex volume and latex dry rubber content.
