Abstract

To support high mobility and varied terrain, vehicles must have optimal engine performance, especially in the clutch system, which is prone to slipping due to clutch lining wear, increasing the risk of accidents. This study analyzes the wear level of Suzuki Katana clutch linings by comparing KW 1 and KW 2 through hardness, wear, and carbon content tests. The results indicate that KW 1 has a hardness of 251.34 kg/mm², higher than KW 2, which is only 67.82 kg/mm². The wear value of KW 1 is 0.003×10⁻⁴ mm³/kg.m, lower than KW 2 at 0.0086×10⁻³ mm³/kg.m. The carbon content in KW 1 reaches 44.0739%, higher than KW 2 at 32.3462%. These findings show that the higher the hardness of the clutch lining, the lower its wear rate, making KW 1 a better choice as it is more durable and resistant to wear.

Abstract

Penelitian ini bertujuan untuk menganalisis perbedaan sifat mekanik dan komposisi material pena pemukul pada senapan SS1-V1 buatan Pindad dan senapan FNC buatan Belgia. Metode yang digunakan meliputi pengujian komposisi kimia menggunakan spektrometer, pengamatan struktur mikro dengan mikroskop optik, serta pengujian kekerasan menggunakan metode Vickers. Hasil penelitian menunjukkan bahwa kedua material termasuk baja karbon sedang, namun memiliki perbedaan kandungan unsur seperti karbon (C), nikel (Ni), kromium (Cr), dan tembaga (Cu). Nilai kekerasan rata-rata pena pemukul FNC sebesar 379,46 kg/mm² lebih tinggi dibandingkan SS1-V1 sebesar 275,67 kg/mm². Selain itu, kandungan tembaga yang lebih tinggi pada SS1-V1 menyebabkan material lebih lunak dan cenderung mudah patah. Dengan demikian, pena pemukul FNC memiliki performa yang lebih baik dari segi kekerasan dan ketahanan terhadap keausan.
