The aim of this research is to find out the effluence of woven fabric of to synthetic leather conserned from elongation at break and peel resistance. This research was done by varying the fabrics used for synthetic leather namely flannel, mori and 3 kind of T.C. fabric. The result of physical examination of the elongation at break and peel resistances value of 2,52 Kg/cm2 and ath wart 1, 54 Kg/cm2 and the highest elongation at break 76,24% is T.C. facric. INTISARI Penelitian inibertujuan untuk mengetahui bahan penguat- penguat terhadap kulit imitasi ditinjau dari sifat perpanjangan putus dan ketahanan rekat. Penelitian ini dilakukan dengan memvariasikan jenis bahan penguat yang akan digunakan untuk kulit imitasi yaitu kain fanel, mori dan tiga jenis kain kaos. Dari hasil pengujian fisis perpanjangan putus dan ketahanan rekat menunjukkan bahwa kulit imitasi dengan kain flanel ketahanan rekat arah membujur 2,52 Kg/Cm2 dan melintang 1,54 Kg/Cm2 an perpanjang tertinggi adalah kain kaos.

The objective of the researc is to know the influence of carbon black as filler of the properties tensile strength and compression deflection for dock vender. The research was done by using standarcompound for dock vender in which the carbon black as filler was varied at 45, 50, 55, 60, 65, and 70 parts for every 100 parts of natural rubber. Statistical analysis paint out that there is no significant deferences. The application carbon black 45 parts will give the best compound with the tensile strength 19,22 N/mm2 and compression set deflection 6,67%. INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh bahan pengisi carbon black terhadap sifat tegangan putus dan pampatan tetap untuk batalan karet dermaga. Penelitian ini dilakukan dengan memvariasi jumlah carbon black yang ditambahkan ke dalam kompon standar dengan variasi 48, 45, 50, 55, 60, 65 dan 70 bagian pada setiap 100 bagian karet. Analisa statistik menunjukkan bahwa sifat tegangan putus dan pampatan tetap tidak berbeda nyata, hasil uji terbaik dengan jumlah karbon black 45 bagian dengan memberikan tegangan putus 19,22 N/mm2, pampatan tetap 6,67%.

The aim of the research was to find out the dock vender compound which have optimum hardness and tearing resistance. The research was done by using standar compound for dock vender in which the carbon black as a filler was varied at 40; 45: 50; 55; 60; 65 and 70 parts for every 100 parts of natural rubber. Testing results show that optimum hardness was found at a compound with 55 parts of carbon black by the value of 60.40 shore A, whereas the tearing resistance show that there are no significant defferences by variation of carbon black. Optimum tearing resistance was given by the compound with 45 parts of carbon black.
