Abstract: Public Works Department (DPU) of Tegal Regency in 2018 has formed a quick response maintenance unit that is in charge of carrying out road maintenance. The type of asphalt used to repair the road is cold mix asphalt. The objectives of this study are: 1. To find out the procedures for carrying out road maintenance through a quick response maintenance at the Public Works Department (DPU) Tegal Regency. 2. To find out the procedure for using cold mix asphalt as material for road repairs at the Public Works Department (DPU) of Tegal Regency. The procedure for maintaining the road through a quick response maintenance at the Public Works Department (DPU) of Tegal Regency with the cold mix method is as follows: 1. Initial assessment after complaints from the public. 2. Direct inspection to the field, 3. Determination of the authority and responsibility on the inspected road of the Unit Quick Response Maintenance of the DPU of Tegal Regency, 4. Implementation of road handling using cold mix asphalt and aggregate. The way to use the asphalt cold mix conducted by Unit Quick Response Maintenance of the DPU of Tegal Regency is as follows: the holes in the road are cleaned, preparing asphalt emulsion, the holes are with emulsion evenly, if the hole depth is more than 5-10 cm, then filled with aggregates 2/3 and or 1/2, laying the cold mix asphalt in the hole evenly, compacting the expanse with the iron wheel or stamper, and finished, the road ready to be used. The procedure for maintaining the road through a quick response maintenance at the DPU of Tegal Regency with the cold mix method has a time efficiency value of 600% which is obtained from the distribution of time needed for maintenance with the hot mix asphalt method as much as 6 hours compared to the time required by the asphalt cold mix method for 1 hour.

Abstract: Along with the increasing economy in the Majenang area as a center for agricultural and plantation products, transportation access is urgently needed to support the distribution of agricultural products and small industries. The only access for public traffic from West Java to Central Java via Majenang City is the Wangon National road – the West Java border, so that on this road traffic jams and accidents often occur. To reduce congestion and reduce traffic accidents, the Cilacap Regency Government opened an alternative route through the district road section from Wanareja – Nyakra – Cigaru – into the Majenang northern ring road which crosses the Cijalu river, so bridge access is needed. Cijalu Bridge is one of the bridges located over the Cijalu River, Majenang District, which is an alternative route to support the smooth flow of traffic between Cilacap Regency and Banjar City, West Java Province URI: http://192.168.252.215:8080/xmlui/handle/123456789/172 Files in this item: 1

Abstract: The road section Tanjung - Kersana is a Regency road that connects two sub-district capitals, namely Kersana District and Tanjung District, along with the development of industry in Kersana District and Tanjung District resulting in an increase in the volume of vehicles on the Tanjung - Kersana road section. This study aims to determine the dimensions, types and levels of damage to these roads. The research was conducted by means of a survey to obtain primary data so that it can be used as a reference for handling road maintenance. The method used is the PCI (pavement condition index) method. On the Tanjung – Kersana STA 0+000 to 6+000 road section, the types of crocodile skin (0,06%), crack damage (0,01%), edge cracks (0,42%), holes (0,01%), patches with a PCI value = 75 are included in the very good category. Handling carried out refers to the Practical Guide to Road Maintenance (1992) in the form of asphalting (P2), filling cracks (P4), filling holes (P5). So the road must be repaired immediately so that the damage does not get worse. Files in this item: 1

Abstract: Trans Semarang is a BRT (Bus Rapid Transit)-based mass transportation service that operates in the city of Semarang. This bus is operated to relieve congestion in the city of Semarang which is increasing. The thing that distinguishes Trans Semarang from other city buses is the automatic door which is located higher, so that passengers can only board at the BRT stop (also known as the shelter). This is what makes it the same as the Transjakarta busway concept, even though Trans Semarang does not have a special BRT lane. Trans Semarang Corridor IV was inaugurated on Monday, March 31, 2017, in the Rectorate yard of the Widya Puraya campus, Tembalang campus, Diponegoro University, which was the longest corridor at the time of its launch. With routes from Meteseh, Tembalang, PRPP, and using the 2016 Ministry of Transportation assistance fleet (same fleet as Trans Jogja).Now in the operational journey, Trans Semarang prioritizes safety, comfort, reliability, affordable and environmentally friendly factors which are the main things in service to the community. So that researchers are interested in analyzing the operational performance of the Trans Semarang Bus, especially the corridor VI line which operates in 2017. This analysis includes in terms of loading factors, the number of up and down passengers, travel time, passenger comfort and passenger satisfaction survey analysis. Files in this item: 1

Abstract: Flood is a condition of the phenomenon of natural disasters that have a relationship withamount of damage in terms of life and material. Flood starts from an increasepopulation, climate change and land use change. Drainage capacitywhich is small and the amount of sediment in drainage causes flooding / flooding.Other problems also arise from household wastewater. Urban areas that aresolids cannot treat waste water individually. So, waste water willflow in urban drainage systems. In this study, rain plays an important role in the evaluation and planning of drainageurban area. Data needed for rainfall data, land use data and datatopography. The rainfall data used is the maximum daily rainfall datareward station with a comparison of other stations. Rainfall data is analyzedwith the Log Person III and Gumbel methods then tested by Chi Square forchoose the distribution of statistics received. Rainfall data is then applied inthe intensity of rainy days with the mononobe method. Rain intensity is useful forcalculate peak discharge with a rational method.Based on the data, flooding in several channels in Tegal Barat was like on the roadPineapple, Rambutan Road, Lumba Lumba Road, Cinde and Bawal Road. The evaluation is in the form of analyzing the discharge of each drainage channel atall of Tegal Barat region. After evaluation there are several channelsdrainage that needs re-planning such as the channels of pineapple and western baroque, cinde and dolphin channels; andsome drainage channels need normalization like the Bawal canal.
