A research have been conducted about the characteristics of belt conveyor by using coconut shell charcoal filler material. The study aims to compare the physical properties of rubber compound for belt conveyor using coconut shell charcoal filler with carbon black filler material. The composition of rubber compound consist of natural rubber, polymer, mineral oils, TBBS, coconut shell charcoal and carbon black. Substitution of coconut shell charcoal to carbon black was done by varying the weight of coconut shell charcoal for 25 phr, 35 phr and 50 phr for comparison, data characteristic of belt conveyor rubber compound using carbon black type for ISAF, HAF, and FEF is used. The results showed the use of coconut shell charcoal as filler for belt conveyor compound has not been able to provide good physical properties such as carbon black. The highest physical properties of compound is obtained at the weight of coconut shell charcoal at 50 phr with the value of tensile strength (70 kg/cm2), elongation at break (320%), tear resistance (36 kg/cm2), hardness (62 shore A) and abrasion resistance (1.1 mm/kgm).

Karbon hitam merupakan bahan pengisi penguat komersial industri dengan harga yang relatif tinggi yang sering digunakan dalam pembuatan barang karet. Sementara kaolin sangat berpotensi dari sisi sifat fisik, ketersediaan dan harga untuk dijadikan bahan pengisi pendamping dalam pembuatan barang karet alam. Penelitian ini bertujuan untuk mempelajari pengaruh komposisi karbon hitam dan kaolin terhadap sifat fisik, tarik, dan ketahanan usang vulkanisat karet Alam. Kombinasi karbon hitam: kaolin dalam penelitian ini yaitu 50:20; 40:30; 30:40; dan 20:40 phr, dilakukan sesuai dengan proses pembuatan vulkanisat karet alam ASTM D3182. Hasil penelitian menunjukan bahwa dominasi kaolin terhadap karbon hitam memperngaruhi perubahan kekerasan, kuat tarik, dan perpanjangan putusnya. Perbandingan komposisi karbon hitam dan kaolin tidak memberikan efek terhadap ketahanan usang vulkanisat karet alam. Hasil spektra FTIR menambahkan informasi dispersi karbon hitam dan kaolin pada matriks karet alam perlu ditingkatkan.

The research aimed to get the best formulation of tire compound motorcycle productions with used silica carbida nano composite as filler to meet the specifications of the market. The experiment was designed as Factorial Randomized Completely Design with two factors as treatments, and each combination of the treatment was gone through trials for three times. The first factor was the particle size of silica carbida nanocomposite (40-60 nm, 80-100 nm and 100 mesh (without nano particle size) and the second factor was vulcanization time (30 minute and 40 minute). The parameters were hardness, tensile strength, elongation at break, abrasive resistance and ageing resistance. The results showed that combination of particle size silica carbida nano composite and vulcanization time had significant effects on the hardness, tensile strength, elongation at break, abrasive resistance and ageing resistance.
