Abstract

Electric road sweepers often face damage to wire broom components due to manual operation errors, particularly when navigating obstacles like speed bumps. To mitigate this, an automatic arm lifting system using proximity sensors was developed to enhance efficiency and extend broom lifespan. This study focused on designing the wiring, determining optimal sensor detection distances, and assessing sensor angle inclinations for an electric road sweeper prototype. Functional testing determined that Sensor A should be placed 60 cm from the wire broom with a tilt angle of 42.2Ëš, a distance of 2936 mm to the ground, and 2800 mm to the object for lifting commands. For Sensor B, the lowering command requires a tilt angle of 49.4Ëš, a distance of 20 cm from the wire broom, 2692 mm to the ground, and 2200 mm to the object. These settings ensure the system effectively lifts the sweeper arm over obstacles, enhancing both efficiency and durability. The findings demonstrate the potential for advanced sensor technology to improve urban cleaning equipment and support sustainable city maintenance practices.

Abstract

Persaingan di industri otomotif menuntut peningkatan kualitas produk untuk memenuhi kebutuhan pelanggan.Penelitian ini menganalisis kualitas radiator cover merek ARM dengan pendekatan Quality Function Deployment(QFD) dan House of Quality (HoQ). Data diperoleh melalui survei terhadap 30 konsumen yang telah menggunakanproduk selama lebih dari enam bulan, serta wawancara dengan produsen dari divisi research and development (R&D)dan produksi. Matriks HoQ digunakan untuk menerjemahkan kebutuhan pelanggan menjadi spesifikasi teknis produk.Hasil penelitian menunjukkan bahwa desain produk (19%), material berkualitas (16%), variasi warna (16%), dankeseimbangan harga-kualitas (16%) merupakan prioritas utama dalam pengembangan produk. Dibandingkan dengankompetitor, produk ARM menunjukkan keunggulan dalam aspek desain dan kualitas material. Penelitian inimemberikan rekomendasi strategis bagi produsen untuk mengembangkan produk secara berkelanjutan yang lebihsesuai dengan kebutuhan pasar, serta memperkuat posisi kompetitifnya di industri otomotif nasional

Abstract

The increasing use of motorcycles necessitates the development of more efficient and environmentally friendly fuel alternatives. This study examines the effect of mixing methanol with pertalite fuel on engine performance and exhaust emissions in carburetor motorcycles. The fuel variations tested include M0, M5, M10, M15, M20, and M25. Performance testing was conducted using a dynotest, while exhaust emissions were measured with an emission gas analyzer. The results indicate that M25 produces the highest torque and power output, particularly in the 2500–8500 rpm range. Additionally, M25 significantly reduces HC and CO emissions, with HC at 108.33 ppm vol and CO at 0.19% vol, compared to M0. The findings suggest that methanol-enhanced fuel improves combustion efficiency, enhances engine performance, and lowers emissions. Thus, methanol-pertalite blends offer a promising alternative for improving carburetor motorcycle performance while reducing environmental impact.
