The aim to be achieved from this research activity is to provide an overview of the factors and causes of cracks, labar and crack depth on the concrete slab of the vehicle floor of the parking building and recommendations for improvement methods. This research method is a used research method and is a success story of crack evaluation and handling methods that have been carried out. The results showed that the crack width that occurred was 0.624-1.022 mm vs. 0.33 mm, out of tolerance. The results of the deflection measurements also show an average deflection in the concrete slab of the vehicle floor is 5.8-10.5 Cm and indicates that the crack has reached the concrete reinforcement, out of tolerance. With the results of this study, it is recommended that improvements be made with crack injection methods using low-pressure injection tools and specifications of an epoxy resin material.

Stabilization is an attempt to improve the physical and mechanical properties of the soil so that it meets specific technical requirements. One method of stabilization is the addition of portland cement additives. This study aimed to compare the CBR values of soft soil of peat before and after stabilization with portland cement and to determine the effect of variations in ripening time on carrying capacity of soft soil peat. Soft peat soil used was taken from Handil Bakti Village, Alalak District, Barito Kuala District, South Kalimantan Province. Variations in the addition of cement levels used 5%, 10%, and 15%, while the variety of curing time starts from 7 days, 14 days and 21 days. In the results of the modified Proctor compaction test, the addition of cement levels in the soft soil of peat was shown to increase the maximum dry weight volume (γd) value continuously. While the value of optimum water content (ωopt) has decreased which is not too significant at each addition of cement content. For the value of the soft soil type of peat mixed with cement, the increase in weight compared with the original soil type weight. In CBR Laboratory testing using modified Proctor compaction at 15% cement content addition and 21 days curing time, the maximum CBR value of the Laboratory was 18.039%. The addition of Portland cement has been shown to increase the CBR value and the carrying capacity of the soil

In this research, we want to experiment to find out the compressive strength of medium quality concrete K-350 with ingredients added MASTER RHEOBUILD 6, whose function is to accelerate hardening, improve the quality of concrete, reduce water use and increase the value of slump. However, it should be noted that errors in dosages and how to use added ingredients can be detrimental to the quality of concrete. The results of the study show that the addition of 0.25, 0.5 and 0.75 liters per 50 kg of cement can increase the concrete compressive strength. The compressive strength of concrete with the addition of 0.25 liters/50 kg of cement has increased 362.67 kg/cm² from the normal concrete compressive strength of 350.58 kg/cm2. The addition of 0.5 liters/50 kg of cement has increased again to 373.24 kg/cm², and the addition of 0.75 liters/50 kg of cement has increased the concrete compressive strength to 379.29 kg/cm² of normal concrete. Comparison of compressive strength before and after addition of admixture with an increase of 3.45% in addition of 0.25 liters/50 kg of cement, 6.47% in addition of 0.5 liters/50 kg of cement and 8.19% in addition of 0.75 liters/50 kg of cement.

Asphalt Concrete-Wearing Course (AC-WC) has been used widely in Indonesia as a surface layer, because of its water-resistant nature and high durability. An essential characteristic of Asphalt Concrete is that its continuous graded aggregate produces a pavement layer with high stability properties. Fillers as fillers in asphalt mixes. In this study, lime was used as a substitute for fillers in the AC-WC mixture. Extinguished lime is a material that passes the no. 200 (0.075 mm), as the primary condition for filler material. The purpose of this study was to determine the Marshall characteristics of the AC-WC mixture using extinguished lime fillers and to assess the performance of the mix and the effect of quenched lime fillers in the AC-WC mixture. The research method was carried out in several stages starting from inspection of 60/70 asphalt penetration, abrasion testing (Los Angeles), screening analysis, aggregate specific gravity testing, Sand Equivalent testing, testing of concrete mixture particular gravity up to testing with Marshall tools. From the results of the study, the use of extinguished filler lime in the AC-WC mixture showed that the use of quenched lime as a filler substitute fulfilled the requirements of stability, flow, VFB, VMA and Marshall Results.

The population growth rate continues to increase directly proportional to the rate of environmental damage. This is due to the increasing need for clothing, food, and shelter. Or primary needs and secondary needs. For example, the impact of floating houses on pollution of the Kahayan River in the City of Palangka Raya, Central Kalimantan. One example of the impact that will be caused is river siltation, river water pollution, and the generation of garbage around the river. The purpose of this study was to identify the silting of the Kahayan River due to sedimentation and to determine the crossing of the Kahayan River in the study area. The research location was in the Kahayan Palangkaraya Tugu Soekarno River Catchment Area to Ropi Ropi. In the sedimentation calculation using USLE modification (MUSLE) has calculated the results of the increase in sediment in the river. The Kahayan River has an area of 81,648 km2, a length of 600 km, a width of 500m, its depth reaches 7 m and empties into three regencies between the cities of Palangkaraya, Kabupaten Gunung Mas, and Kabupaten Pulang Pisau. From the calculation of flood discharge, the peak discharge (Qp) is 0.0105 km². Prediction of Sedimentation Rate using the MUSLE Method of each Protection Forest = 0, Sebangau National Park = 901, Tourist Park = 73, Forest Park = 112, Tetat Production Forest = 3.422

The city of Palangka Raya has these peatlands spread across several regions including populated areas. This needs special attention in the world of concrete construction because the peatland has peat water with a high level of organic matter, low acidity (pH) which results in acidic water. The acidity of peat water will cause problems in concrete construction because it will affect the physical and mechanical properties of concrete which will make the concrete corrosive. This research method is by making 27 K-250 concrete samples, each of which three examples will be immersed in peat water, Kahayan river water, and tap water for one month, two months and three months. The results showed that the concrete soaked in peat water had the most significant decline compared to the concrete soaked in Kahayan river water and tap water, which was 8.798% of the planned concrete compressive strength of 250 kg / cm2 while the concrete with river water immersion decreased by 5.882% and tap water immersion 2.966% from the planned concrete compressive strength of 250 kg / cm2.

Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A
