ABSTRAK Pemadatan merupakan stabilitas tanah secara mekanis. Setelah dipadatkan, susunan partikel-partikel tanah menjadi lebih padat sehingga mempunyai sifat-sifat teknis yang lebih baik dari sebelumnyaBeberapa macam tipe alat pemadat telah dikembangkan oleh banyak pabrik. Besarnya energi pemadatan tergantung pada berat alat pemadat, tekanan dan alat pemadat yang digunakan.Alat pemadat tipe penggilas kaki kambing (sheeps’ foot roller) banyak dipakai untuk pemadatan tanah lempung, dimana alat ini memiliki kaki-kaki (pad) yang berfungsi sebagai peremas tanah yang memberikan tekanan yang lebih besar.Penelitian ini menganalisis besaran energi yang dihasilkan oleh alat penggilas kaki kambing untuk memadatkan tanah 1 hingga 8 lintasan.Hasil penelitian menunjukan energi yang dihasilkan setiap lebar roda dengan kecepatan 8 kpj adalah 64,43 joule untuk 1 lintasan dan semakin banyak jumlah lintasan maka energi yang dihasilkan semakin besar hingga mencapai 515,47 joule.ABSTARCT Compaction of the soil stability mechanically. Once solidified, the composition of the soil particles become more dense and therefore have technical properties better than ever Some types of rollers have been developed by many factories. The amount of compaction energy depends on the weight of the roller, and the pressure rollers are used. Foot roller compactor type of goat (sheeps' foot roller) is widely used for compaction of clay, on which it has legs (pad) that serves as peremas land provides greater pressure. This study analyzes the amount of energy generated by a leg of lamb for pressing to compact the soil 1 to 8 tracks. The results showed wide energy produced each wheel speed of 8 kph is 64.43 joules for one track and the more the number of passes, the greater the energy produced to reach 515.47 joules.

Jambi City is a city that is developing rapidly in various fields. To support this aspect, various supporting facilities are needed, one of which is good physical and non-physical infrastructure. Physical infrastructure includes facilities and infrastructure, and use management. The need for physical infrastructure is very important to support easy accessibility of activities and developments in urban areas. Highway planning and construction is one of the factors in the formation of sustainable areas, including the type of infrastructure development that serves community needs, including the process of opening up traffic space to connect one area to another. The aim of this research is to analyze the traffic movement of Simpang Rimbo at each arm of the intersection and to find out the level of traffic flow service on the road sections at the intersection of the three West Ring Road-3, Jalan Captain Pattimura, and Jalan Mandalo. The research method is to evaluate existing traffic signals and their relationship to road geometric planning. The results of this research are an evaluation and analysis of the geometric planning of traffic signals planned to lower the LOS value, meaning increasing the level of service at the Rimba intersection in the next 10 years.

Traffic control at intersections with a high volume of vehicle traffic requires regulation with traffic lights. With the regulation using traffic lights, it is hoped that it can reduce the number of queues experienced by vehicles, compared to those that do not use traffic lights. One of the intersections located in the Jambi City area which is equipped with vehicle traffic control using traffic lights is Hajj Dormitory Intersection. This intersection is a confluence of four arms of the road namely, Jl. H. Agus Salim â€“ Jl. H. Adam Malik â€“ Jl. H. Yunus Sanis â€“ Jl. H. A. Roni Sani, located in the Handil Jaya Village area, Jelutung District, Jambi City. This intersection is a connecting road between regions including; office areas, shops, schools, markets, hospitals, campuses, tourist attractions, settlements, and various other destinations. At these intersections often experience traffic congestion problems, especially during the morning rush hour, afternoon rush hour and evening rush hour. This problem can be seen from the long queue of vehicles that occur. This study aims to analyze the traffic performance of the intersection, as well as obtain the service level of the existing intersection at the intersection of the Hajj Dormitory in Jambi City. The method used in calculating the analysis uses the 2014 Indonesian Road Capacity Guidelines for the capacity of the APILL intersection. The results of the study obtained several conclusions in the form of (1) the performance of the Jambi City Hajj Dormitory intersection, the existing conditions work less than optimally in serving the existing vehicle traffic flow, where the delay value that occurs is greater than 60 seconds/skr for all approaches. For Jl. H. Agus Salim the delay value is 74 seconds/skr and the queue length is 144 meters, Jl. H. Adam Malik delay value of 106 seconds/skr and queue length of 156 meters, Jl. H. Yunus Sanis the delay value is 134 seconds/skr and the queue length is 140 meters, and Jl. H. A. Roni Sani has a delay value of 228 seconds/skr and a queue length of 166 meters. (2) The service level for all approaches is F, where the delay value is greater than 60 seconds/skr. With an average intersection delay value of 116 sec/skr, the level of service F.

The asphalt concrete layer is the top layer of road pavement construction which is in direct contact with vehicle wheel loads and the influence of weather. One type of asphalt concrete layer is Asphalt Concrete – Wearing Course (AC–WC). Asphalt functions as an aggregate adhesive. In asphalt concrete mixtures it is very important to maintain its characteristics. During the maintenance period, the mixture will easily experience striping or peeling of the asphalt from the aggregate. To maintain and improve the properties of asphalt, one way is to use an anti-striping additive, this additive is Wetfix-Be, which is a compound that contains chemicals. Anti-peeling materials are only used if the residual Marshall stability value (IRS-Index of Retained Stability) or the Indirect Tensile Strength Ratio (ITSR) value of the asphalt mixture before adding the anti-peeling agent is less than required. If an anti-flaking agent must be used then before the anti-flaking agent is added to the mixture, the residual marshall stability (after 24 hour immersion, 60 °C) must be at least 75%.

Roads are land transportation infrastructure which includes all parts of the road. Good road conditions really support the smooth running of the economy in an area so that road maintenance is very important so that the smooth running of the economy is not disrupted by poor road infrastructure. The form of road maintenance depends on the results of the assessment of the condition of the damage. The road surface has been determined visually, the method used is the Surface Distress Index (SDI) method. According to Suswandi (2008), assessing the level of road damage is an important aspect in determining road maintenance and repair activities. Small damage that is not immediately anticipated causes the damage to become more severe, the impact becomes wider and reduces the capacity of the road itself. Therefore, researchers want to technically review the condition of the surface pavement of Jalan Swadaya Raya in Alam Barajo District using this method visually, with a length of 800 m and a width of 4 m experiencing damage in several segments which is quite disturbing the smooth running of the road.

The density test for soil in the laboratory can be a mild density test (standard proctor) and a modified density test (modification proctor). Both types of compaction provide different levels of density. This paper aims to analyze the energy produced by both types of compaction. The results show that the compaction modification energy is greater than the standard compaction energy. These results are influenced by the number of layers and the difference of the mass of the pounder on both types of compactionKey words: compaction energy, standard proctor, modified proctor
