    Abstract
    Salah satu tahap dalam pembuatan benang karet adalah menghitung bilangan swelling indeks compound dari benang karet, karena Swelling indeks compound berhubungan erat dengan elastisitas dari benang karet. Dari hasil percobaan, nilai yang diperoleh adalah 2,13 – 2,63 mm². Bilangan swelling indeks compound telah memenuhi standar perusahaan yaitu 2,34 – 2,63 mm² . Apabila swelling indeksnya terlalu besar atau terlalu rendah, akan dapat mengakibatkan berkurangnya elastisitas dari benang karet.
     
    One of phase in making of rubber yarn is count the number swelling make an index to the compound from rubber yarn, because Swelling make an index to the compound closely related with the elasticity from rubber yarn. From attempt result, value obtained is 2,13 - 2,63 mm². number Swelling make an index to the compound have fulfilled the company standard that is 2,34 - 2,63 mm². Swelling index too big or too low, will be able to result to decrease it elasticity from rubber yarn.
