Abstract

Perkerasan pada umumnya menggunakan bahan campuran dari aspal dan juga memiliki sifat elastis jika menerima beban di atasnya. Sampai saat ini belum ada rumus khusus yang dibuat untuk merencanakan tebal perkerasan di tanjakan, padahal perkerasan jalan ditanjakan akan berbeda kondisinya dibandingkan dengan perkerasan dijalan datar sehingga kebutuhan tebal perkerasannya pun tidak sama. Untuk itu akan dihitung berapa ketebalan perkerasan jalan tersebut baik itu di jalan datar maupun ditanjakan menggunakan rumus AASHTO 1993. Dari hasil analisa nilai Modulus Resilien (MR) berdasarkan nilaiCBR, didapat nilai MR pada jalan datar sebesar 6447,34 psi, sedangkan nilai MR pada jalan tanjakan sebesar 4144,27 psi.Hasil yang didapat dari perhitungan pada kedua kondisi tersebut memberikan nilai ketebalan lapisan yang berbeda. Untuk perkerasan di jalan datar didapat tebal ATB = 11 cm, Base A = 14 cm, dan Base B = 40 cm, sedangkan untuk perkerasan ditanjakan didapat tebal ATB = 12 cm, Base A = 13 cm, Base B = 60 cm. Selain itu dihitung juga nilai Modulus Elastis (E) tanah dasar dari kedua kondisi jalan, yaitu jalan datar didapat nilai E = 68,711 psi dan nilai E di jalan tanjakan E = 62,586 psi. Dari hasil analisa tersebut, dapat disimpulkan bahwa dengan Metode AASHTO’ 1993 ketebalan perkerasan pada jalan datar dan jalan tanjakan menghasilkan perbedaan nilai ketebalan perkerasan yang signifikan. Oleh karena itu, diharapkan agar perencana lebih teliti lagi apabila merencanakan suatu perencanaan jalan sehingga perkerasan tersebut tidak cepat rusak. disamping itu juga disarankan agar Bina Marga mempunyai metode khusus untuk merencanakan tebal perkerasan jalan di tanjakan.Kata kunci: Metode AASHTO 1993, perkerasan jalan di tanjakan.

Abstract

One type of soil that has many problems in a construction development is clay soil. Clay soil originating from Jl. Abdul Rahman Hamid, Tenayan Raya District, Pekanbaru has a problem where there are cracks and waves on the road due to non-uniform subsidence. To deal with problems in the soil one way that can be done is by stabilization. The purpose of this study was to determine to determine the effect of a mixture of rice husk ash on the CBR value and to find the optimal mixture. The research uses the laboratory test method, by testing CBR on variations of the rice husk ash mixture amounting to 4%, 7%, and 10% of the dry weight of the soil with unfermented conditions, 7 days of incubation and 4 days of soaking. The effect of using rice husk ash on the value of CBR in unfermented conditions increased in the 4% and 7% rice husk ash mixture, but decreased in the 10% rice husk ash mixture. The influence of the use of rice husk ash mixture on 7-day fermentation increases the CBR values. Whereas in immersion conditions, the CBR value tends to decrease with increasing rice husk ash levels. The optimal mixture in CBR occurred in a mixture of 10% rice husk ash with a 7-day fermentation condition of 12.85%. Thus, it is concluded that the use of the percentage of the mixture as well as the length of the soaking and soaking days used can affect the CBR value of the soil.

Abstract

Traffic accidents are unforeseen and unintentional incidents involving vehicles or other road users, leading to human casualties (including minor injuries, serious injuries, or fatalities) and property damage. This study aims to analyze accident rates by examining contributing factors such as causative elements, accident black spots, and the impact of road user characteristics, including age, occupation, and driver condition. The research employed an observational method, involving direct field surveys along the Ujung Tanjung–Bagansiapiapi road section in Rokan Hilir. The findings revealed that human factors were the predominant cause of accidents, accounting for 61 incidents, while road-related factors contributed to 5 accidents. The age group most affected by accidents was 21–25 years, which resulted in 25 fatalities. Additionally, the study identified two critical black spots: the Jumrah Ujung Tanjung section, with an accident rate of 0.310, and the Tanah Merah Jumrah section, with an accident rate of 0.274. To mitigate accident rates, it is crucial to enhance road safety by installing traffic signs and other supporting infrastructure.
