Analisis Fluktuasi Arus Lalu Lintas Kota Palu (Studi Kasus: Kota Palu Bagian Barat)

Traffic flow is due to the interaction between the system of activities with transport network system inthe form of movement of vehicles on the highway. This type of land use led to a different traffic flowfluctuations every street throughout the day.The purpose of this study was to determine fluctuations in traffic, timing and magnitude of peak hours ,percentage of traffic is covered by long observation of traffic flows.Traffic flow data collection done on location, KH. Wahid Hashym Street, Sis Al Jufri Street andPangeran Diponegoro street, West Palu. The type of data on the study include primary data andsecondary data. The primary data include the volume of data traffic flow on roads. Secondary dataincludes data of road networks, land use maps, maps of the Palu City. The primary data werecollected with a traffic volume survey on Monday – Thursday and Saturday.The result of the study was to found that the secondary arterial road network system, the peak hourson weekdays occurred at 4:00 p.m. to 5:00 p.m. with the traffic flow of 2168 pcu /h, at the weekendoccurred at 08:00 to 09:00 with traffic flow for 2330 pcu/h. At the secondary collector road networksystem, the peak hours on weekdays occur in at 07.00 - 08.00, the traffic flow of 1928 pcu/hour, atthe weekend occurred at 4:00 p.m. to 17:00, the traffic flow of 1638 pcu h.The results of fluctuation analysis of traffic flow on weekdays for a secondary arterial roads was foundthat if the survey was conducted for 16 hours then the time most remains are 6:00 a.m. to 10:00 p.m.,with the volume of traffic is 92% covered. When the survey was conducted for 12 hours then the besttime is 07:00 to 19:00, traffic volume is 73.42% covered. If the volume of traffic surveys carried out for 8hours, the best time is at 11:00 to 19:00, traffic volume data covered is 48.68%.The results on the secondary collector streets on working hours to get that when the traffic volumesurvey for 16 hours then the best time is 06:00 to 22:00 with traffic volume covered 92.34%. . When thesurvey was conducted for 12 hours then the best time is 07:00 to 19:00, traffic volume is 77.02%covered. . If the volume of traffic surveys carried out for 8 hours, the best time is at 07:00 to 15:00,traffic volume data covered is 54.15%

Evaluasi Kerusakan Jalan Menggunakan Metode Pavement Condition Index (PCI) dan Surface Distress Iindex (SDI) Studi Kasus Jalan Pue Bongo – Kota Palu

Pue Bongo street is one of the urban roads where the pavement is damaged. Based on the observations made, there are many types of damage found, disturbance to road users and have a major impact on safety and comfort.The purpose of this research is to knowing the condition of the damage that occurred and the appropriate form of handling the problem of damage to the Pue Bongo street. Data collection was carried out along the Sta.0+000 to Sta.1+525 roads, namely visually. The data required are secondary data and primary data. Secondary data were obtained through the Department of Highways and Spatial Planning of Central Sulawesi Province. Primary data was obtained through a visual road condition survey using the PCI and SDI methods. The results of the analysis of the condition of the Pue Bongo pavement with an average PCI value of 37.90 indicate poor conditions, while the SDI average value is 76.56 with moderate conditions. The recomended treatment based on PCI method is reconstruction/recycling, for the SDI method the recomended treatment is maintenance. As for the handling of damage basd eon the MDP 2017, namely peeling and replacing the material in certain areas

Pengaruh Nilai Abrasi Agregat terhadap Karakteristik Beton Aspal

Unsur terbesar penyusun campuran beton aspal adalah agregat, sehingga kualitas campuranbeton aspal sangat ditentukan oleh kualitas agregat penyusunnya. Salah satu indikator kekuatanagregat adalah nilai abrasinya. Penelitian ini bertujuan untuk mengetahui pengaruh nilai abrasiagregat terhadap karakteristik campuran beton aspal. Variasi nilai abrasi yang digunakan yaitu16,41%, 20,44%, 25,71%, 28,57% dan 35,86%. Diketahui bahwa semakin besar nilai abrasi agregatmaka stabilitas campuran semakin menurun. Nilai stabilitas tertinggi sebesar 1787,477 kgdiperoleh pada nilai abrasi 20,44%. Rentang nilai abrasi yang memenuhi seluruh parameterkarakteristik campuran beton aspal (VMA, VIM, VFB, Flow, Kepadatan, MQ dan Stabilitas) yaituantara 7,592% dan 64,98

Karakteritik Beton Aspal Lapis Pengikat (Ac-bc) Yang Menggunakan Bahan Pengisi Pengisi (Filler) Abu Sekam Padi

Asphalt Concrete Binder Course (AC-BC) Pavement is a type of asphalt pavement located between base layer and wearing course. The study was conducted describing the the effect of the use of rice husk ash onthe characteristics of asphalt concrete AC-BC mixtures. The purpose of this study was to determine thecharacteristics of the asphalt concrete binder course mixtures (AC-BC) which uses rice husk ash as filler,determine the optimum percentage of rice husk filler in AC-BC pavement mixtures. Research materials include coarse aggregate, fine aggregate and rice husk ash. Coarse and fine aggregateobtained from Stone Cruiser of Taipa and Palu River, while rice husk ash obtained fromBiromaru area in Sigi Regency. Asphalt used in this study is Asphalt pen. 60/70 produced by Pertamina.Investigation and testing of these materials has been carried out in the Laboratory of Transportation andHighways, Department of Civil Tadulako University of Palu.Research has been carried out by using rice husk ash filler variation of 0%, 25% and 50%. The datacollected includes characteristics of volumetric and Marshall test characteristics of AC-BC pavementmixture on each rice husk ash content. The data include density, VIM, VMA, VFB, Stability, flow, MarshallQuotient value and residual stability of the mixture. The data is processed and displayed in graphical form, then do a comparative analysis between the characteristics of the AC-BC mixture that uses rice husk ash andwithout rice husk ash.The results of the study found that increasing the percentage of rice husk ash content in the mix AC-BC tendsto increase the use of bitumen content. It can be seen from the increasing value of Optimum Bitumen Content(OBC) on rice husk ash variation of 0% - 50%. The results also gain an increase in the durability of the ACBCmixtureofricehuskashonthevariationof0%- 5%asindicatedbytheincreasedtheresidualstabilityvalueofthe AC-BC pavementmixtures.Maximum stabilityoccursinrice huskashcontentof25%
