Abstract

Highways are land transportation infrastructure that is very important in facilitating economic relations activities. The method used is the SDI (Surface Distress Index) method. The purpose of this study is to identify the types of road damage, analyze the level of road damage using the SDI method and evaluate the SDI value and handling potholes. The length of the road studied in this research is 1000 ± m which is divided into 10 segments with a segment length of 100 m each. The data required for this research is secondary data and primary data. Based on the results of processed field data, 6 types of road damage were obtained. The percentage results on Jalan Ciremai Ujung with an average SDI value of 34 and categorized as having a value in good and moderate conditions so that the percent value (%) in damaged conditions is 90%, moderate 10%, slightly damaged 0% and seriously damaged 0%. And carry out handling by means of routine maintenance on segments 1,2,3,5,6,7,8,9,10 and periodic maintenance on segment 10.

Abstract

The growth and concentration of motor vehicles in developing cities has led to increased demand for urban mobility. Renewed commitments of Asian cities are required in order to achieve the SDG target on urban mobility as well as to enhance overall sustainability of urban transport systems and services. Cities and countries need to track the progress in improving urban mobility. With a view to support evidence based decision, the paper introduces the Sustainable Urban Transport Index (SUTI) of urban transport services, to help summarize, track and compare the state of urban mobility in Asian cities, as model for developing cities in the world. It also presents the results of pilot application of SUTI in four Asian cities: Greater Jakarta; Kathmandu; Hanoi; and Colombo. The four pilot cities were able to collect data, analyzed and assess the state of urban mobility in their city using SUTI. The assessment result supported policy makers to identify policy gaps, prioritize additional measures and investment strategies required to improve urban transport systems and services in each city. The visual output display in spider diagram was useful to comprehend state of all 10 key indicators in a glace. The pilot study demonstrated the usefulness of SUTI tool and the pilot cities were already using the results of SUTI analysis. In Kathmandu additional efforts are required to improve pedestrian infrastructure and facilities, Colombo needed to improve quality and reliability of public transport system, while Hanoi and Greater Jakarta need to put additional efforts to increase mode share of public transport system.

Abstract

Motorcycles produce a variety of sounds. Sound is synonymous with noise. Noise is big enough to have an impact on the comfort of a place that is directly related to the highway. The distance between the hospital building and the road must be taken into account. This distance is important for the realization of patient comfort in the hospital/treatment room. The volume of motorcycles, light vehicles and heavy vehicles must be controlled, especially those passing through schools/places of worship/hospitals. Traffic flow/volume of motorcycles, light vehicles and heavy vehicles have a significant effect on noise. The calculation results obtained the largest equation on the fourth day of research at the third point (sound level meter2), with a contribution of 34.22% at y = 59.11 + 0.3x1 - 0.1x2 - 0.17x3. This equation means that if there is no decrease in the volume of motorcycles, light vehicles and heavy vehicles, the noise level in SLM2 is 59.11dBA. If there is an increase in the volume of motorcycles, light vehicles and heavy vehicles, the noise significantly affects. The results of the second equation from the calculation of the first day at the third point (sound level meter3) with a contribution of 19.30% based on the equation, y = 60.54 + 0.01x1 – 0.01x2 + 0.08x3. This means that if there is an increase in the volume of the motorcycle, the noise on the SLM3 is 60.54dBA. From the results obtained, there has been a decrease in the volume of motorcycles, light vehicles and heavy vehicles that pass through RS Hermina Bogor during the Covid-19 pandemic, because many hospital visitors/users do not travel or self-isolate at home. Decrease in the number of motorized vehicles that pass in front of the hospital. RS Hermina Bogor reached 45%.

Abstract

PT Lill Hajj Wall Umrah is targeted to get 5,226 consumers per year or equivalent to 436 people per month by 2030. The old office in the form of a shophouse with a building area of 119.75 m² for a capacity of 99 people is considered inadequate to serve 436 consumers per month, so PT Lill Hajj Wall Umrah needs a new office with a meeting room of at least 523.2 m².  A new office will be planned based on SNI 2847-2019, SNI 1726-2019, SNI 1727-2020, and PBI 1983. The planning results are in the form of an analysis of the new office structure with building dimensions of 28.30 x 23.35m, four floors with a building area of 4,503 m². The material specifications of the building structure are concrete quality (fc') 41.5 MPa, melted reinforcing steel quality (fy) 400 MPa (BJTS), and 280 MPa (BJTP). Basement floor column dimensions 0.6 x 0.6 m, first to fourth floor columns 0.5 x 0.6 m, rooftop columns 0.4 x 0.4 m, main beam dimensions 0.25 x 0.35 m, child beams 0.25x0.5 m, stair beams 0.25 x 0.35 m, roof deck beams 0.25 x 0.3 m and 0.3 x 0.4 m, concrete slab thickness 0.15 m. The results of structural modeling using the Etabs application showed that there was no over-strength (O/S) in the column and beam structure elements. The results of the design of the new office building Lill Hajj Wall Umrah in the form of a basement floor equipped with prayer room facilities covering an area of 14 m2, a generator room covering an area of 15.28 m2, a pump room covering an area of 15.28 m2, parking covering an area of 781.53 m2. The first floor is equipped with VIP room facilities covering an area of 33.33 m2, a prayer room covering an area of 25.87 m2, a toilet covering an area of 44.93 m2, and a boutique room covering an area of 55.22 m2, and a warehouse covering an area of 12.3 m2. The second floor is equipped with a meeting room covering an area of 47.9 m2, a manager's room covering an area of 36.7 m2, a toilet covering an area of 30.9 m2, a prayer room covering an area of 16.08 m2, a boardroom covering an area of 80.59 m2 and a waiting room covering an area of 45 m2. The third and fourth floors are equipped with toilets covering an area of 25.75 m2, a prayer room covering an area of 23.95 m2, and a ballroom of 383.75 m2. The estimated budget for the construction of lill Hajj Wall Umrah's new office is Rp 7.612.645.721.- and takes 406 working days for construction.

Abstract

Buses as a means of public transportation can greatly reduce traffic problems in urban areas through the use of, among other things, innovative techniques and technologies. The development of innovative technologies increasingly oriented towards the electrification of vehicle propulsion systems is expected to lead to the reduction of harmful emissions, increased vehicle efficiency, improved performance, reduced fuel consumption, and reduced noise. This study aims to determine the comparison of Transjakarta electric buses with conventional buses owned by Transjakarta, identify and evaluate the condition of the electric bus side. This study uses quantitative methods. The results of the study show a comparison of the operational cost calculation as indicated by the calculation of direct costs and indirect costs. The unit price for a bus/km for a diesel bus is Rp. 51,796, on the electric bus Rp. 224,991, and BBG buses for Rp. 82,227. where in the comparison of BOK diesel buses are cheaper than electric buses and CNG. The most expensive cost is the replacement of spare parts, especially the price of the battery which needs to be replaced every 10 years. 3,876, while bbg buses require much cheaper, which is Rp. 630. The calculation results of the electric bus battery consumption on the use of 1 route with a distance of 30.8 on weekdays on average 11.5% while on weekends it is 9.5%. At the kWh consumption, the electric bus requires the consumption of kWh per trip with a distance of 31.4 km is 23.57 kWh. From this value, it is known that the efficiency is 1.3 km/1 kWh. In charging the battery, the average battery charging time on the electric bus is 134 minutes or about 2.23 hours.
