Abstract

Reclaimed Asphalt Pavement (RAP) adalah alternatif material aspal yang dihasilkan dari hasil pemeliharaan jalan.  Namun, aspal RAP telah mengalami penuaan (aging)akibat masa layannya, sehingga kehilangan sebagian sifat reologi dan mekaniknya. Untuk mengembalikan sifat tersebut, diperlukan bahan rejuvenator. Salah satu bahan alternatif adalah Waste Cooking Oil (WCO) atau minyak jelantah.  Penelitian ini bertujuan untuk menganalisis pengaruh penambahan WCO terhadap sifat fisik dan mekanik campuran aspal RAP. Metodologi yang digunakan meliputi uji penetrasi, uji titik lembek (softening point), serta pengujian Marshall. Hasil penelitian menunjukkan bahwa penambahan WCO dapat meningkatkan nilai penetrasi dan menurunkan titik lembek, menandakan peningkatan fleksibilitas aspal. Kinerja Marshall juga meningkat pada kadar optimum WCO, dengan peningkatan stabilitas dan flow yang menunjukkan bahwa WCO berperan efektif sebagai rejuvenator

Hence, this research examined the influence of the public participation and discretion factors to improve the public service quality in TIOSS Office of Bandung Barat Regency. This research used the mixed method. Quantitative method was reflected through survei technique data collection which then was analyzed through Structural Equation Model and Partial Least Square. While qualitative method was reflected through Focus Group Discussion technique. The results were, first, public participation and the discretion had a positive and significant impact to the public service quality. Second, the public participation variable partially had a greater effect than the discretion variable to improve the quality of the public service.
