Abstract

Asbuton is a promising local material that can partially replace petroleum asphalt in AC-WC hot mix asphalt. This study aims to investigate the influence of varying Asbuton B50/30 content on the performance of asphalt mixtures using the Marshall method. The optimum asphalt content (OAC) was determined to be 6.29%, followed by testing with Asbuton contents of 7%, 9%, and 11% of the total asphalt weight. The evaluated parameters included stability, flow, Marshall Quotient (MQ), and volumetric properties (VIM, VMA, and VFB), all assessed against Bina Marga technical specifications. The results indicate that 7% Asbuton content provides the best performance, yielding the highest stability (1977.70 kg) and MQ (632.35 kg/mm), while maintaining volumetric parameters within specification limits. At higher Asbuton contents (9% and 11%), stability and MQ declined, whereas flow and VFB increased, suggesting an over-binder effect that reduces structural integrity. These findings highlight the importance of proper Asbuton dosage control to balance mechanical and volumetric properties. This study contributes to the advancement of knowledge in asphalt pavement engineering by emphasizing the dual role of Asbuton as both a filler and a binder modifier, while also providing a scientific basis for utilizing local materials to support more sustainable pavement development.

Abstract

Extreme weather is one of the main challenges in logistics distribution systems, especially on non-urban freight transport routes in eastern Indonesia. This study aims to analyze the effect of speed, travel time, safety, and transportation costs on freight distribution behavior, taking into account the role of extreme weather. The research method used a quantitative approach with Structural Equation Modeling-Partial Least Squares (SEM-PLS), based on questionnaire data from 300 truck drivers in UPPKB Datae and Maccopa, South Sulawesi. The analysis results show that safety (p = 0.021) and transportation costs (p = 0.001) have a significant effect on distribution behavior. Conversely, speed, travel time, and extreme weather do not have a significant effect. The coefficient of determination (R² = 0.01) indicates that the model can only explain 1% of the variation in distribution behavior, suggesting that other external factors outside the model have a more dominant influence on logistics distribution. These findings emphasize the importance of safety improvement and cost efficiency strategies as top priorities in dealing with extreme weather uncertainty, while also encouraging the development of additional variables to strengthen distribution behavior modeling.

Abstract

Pertumbuhan ekonomi di Kabupaten Sidenreng Rappang mendorong peningkatan volume angkutan barang yang secara simultan memicu praktik Overdimension dan Overloading (ODOL). Penelitian ini bertujuan untuk menganalisis keterkaitan antara karakteristik teknis kendaraan dan perilaku operator dengan tingkat kepatuhan terhadap kebijakan transportasi. Metode penelitian menggunakan pendekatan kuantitatif deskriptif melalui survei terhadap 405 operator truk di Jembatan Timbang Data’e. Data dikumpulkan menggunakan kuesioner, kemudian dianalisis dengan uji validitas, reliabilitas, regresi linier berganda, serta uji asumsi klasik melalui perangkat lunak SPSS versi 25. Hasil penelitian menunjukkan mayoritas operator adalah laki-laki berusia 25–30 tahun dengan tingkat pendidikan sekolah menengah pertama. Kendaraan yang dominan berupa truk dua as berkapasitas 10–15 ton, sebagian besar telah mengalami modifikasi di luar ketentuan standar teknis. Sebanyak 52,49% operator tercatat tidak melakukan penimbangan, 70,12% kendaraan tidak memiliki sertifikat uji laik jalan(KIR), serta 45,43% berada dalam kondisi ODOL. Analisis regresi menunjukkan perilaku negatif operator berpengaruh signifikan terhadap pemahaman kebijakan transportasi dengan koefisien determinasi R² = 0,491. Temuan ini menegaskan bahwa faktor teknis kendaraan dan perilaku operator merupakan determinan utama praktik ODOL. Kontribusi penelitian ini terletak pada penyediaan bukti empiris berbasis data lapangan mengenai determinan kepatuhan operator angkutan barang, serta menawarkan rekomendasi berupa penguatan penegakan hukum dan edukasi teknis guna mendukung keselamatan lalu lintas dan keberlanjutan infrastruktur jalan.
