PENGEMBANGAN SISTEM PEMBERSIH UDARA DOUBLE FILTER BERBASIS PNEUMATIK DAN VARIASI PUTARAN UNTUK EFISIENSI DUMP TRUCK SANY

ABSTRAK
Debu yang tinggi pada area pertambangan batubara menyebabkan filter udara mesin diesel heavy equipment cepat mengalami penyumbatan sehingga menurunkan performa mesin, meningkatkan konsumsi bahan bakar, serta mempercepat frekuensi perawatan. Penelitian ini bertujuan merancang dan menguji alat pembersih filter udara berbasis sistem pneumatik dan mekanisme putar untuk meningkatkan efisiensi proses pembersihan filter primer dan filter sekunder. Metode penelitian meliputi studi literatur, observasi lapangan, perancangan menggunakan SolidWorks, pembuatan prototipe, serta pengujian fungsional terhadap putaran motor dan waktu pembersihan. Hasil pengujian menunjukkan bahwa alat bekerja dengan baik pada seluruh variasi putaran motor dan mampu membersihkan kedua jenis filter secara lebih cepat dibandingkan metode manual. Rata-rata waktu pembersihan filter primer berkurang dari 15 menit menjadi sekitar 6 menit, sedangkan filter sekunder dari 12 menit menjadi sekitar 6 menit. Dengan demikian, alat yang dikembangkan mampu meningkatkan efisiensi waktu perawatan, mengurangi beban kerja operator, serta mendukung keandalan dan produktivitas mesin diesel pada kegiatan operasional pertambangan.

ABSTRACT
High dust exposure in coal mining areas causes diesel engine air filters on heavy equipment to clog rapidly, reducing engine performance, increasing fuel consumption, and shortening maintenance intervals. This study aimed to design and evaluate an automatic air filter cleaning device based on a pneumatic system combined with a rotating mechanism to improve the efficiency of cleaning primary and secondary air filters. The research methods included literature review, field observation, computer-aided design using SolidWorks, prototype fabrication, and functional testing to evaluate motor speed and cleaning time. The experimental results demonstrated that the proposed device operated effectively under all tested motor speed variations and cleaned both filter types significantly faster than the conventional manual method. The average cleaning time for the primary filter decreased from 15 minutes to approximately 6 minutes, while the secondary filter decreased from 12 minutes to approximately 6 minutes. Therefore, the developed device improves maintenance efficiency, reduces operator workload, and enhances the reliability and productivity of diesel-powered heavy equipment operating in mining environments.
