Abstract This study aims to determine and analyze road damage due to waterlogging that occurred in Berastagi City and aims to provide alternative solutions for handling road surface damage in accordance with road damage conditions in the field. Road section. Air currently has roads that are prone to waterlogging, especially at the intersection of Selamat village, hamlet IV, Merdeka sub-district, Karo district. Puddles that occur due to drainage that is not functioning properly and even has no drainage at all. High rainfall has resulted in road sections being damaged which has an impact on the inconvenience of road users passing on these roads, causing traffic jams. Based on the identification of problems at the research location, it is known that there are at least four problems that cause puddles on the road surface, namely relatively high rainfall, poor drainage system, vehicles carrying loads exceeding road capacity, and inappropriate land use around the road. its allotment. This research was conducted using qualitative methods, this method emphasizes more on facts in the field and utilizes existing literature as supporting material. The results of this study indicate that the Berastagi Airway - Simpang Spirit Village, Hamlet Iv, Berastagi City suffered quite severe damage at several points. The results of the analysis in the field show that the problem of standing water that occurs on roads is caused by poor drainage conditions. An alternative solution to standing water is to give advice and discipline the people who use the catchment area as agricultural land or housing so that flowing water can be better absorbed. In addition to aspects of financing policy and maintenance management, it also needs the support of various related parties, including road user stake holders, so they can understand the capabilities and carrying capacity of infrastructure and take responsibility for maintaining it for the sake of continuity of service that provides a sense of security, comfort and dignity to these road users.

Abstract

Bridges are one of the important infrastructure in people's lives, because apart from being a link to facilitate transportation between two or more areas separated by rivers and valleys, the existence of bridges can indirectly increase economic growth in an area. Structurally the bridge is separated into an upper building and a lower building. According to its function, the building under the bridge supports and forwards the load from the bridge top building to a strong and stable / solid soil layer. The building under the bridge consists of an abutment and a foundation, where the abutment can also function as a bridge foundation. The upper structure on a bridge includes, among others, vehicle floors (Deck), bridge girders (Girder), bridge stiffeners, laying bridges (Bearing), and expansion joints. This study focuses on the floor of the vehicle (Deck). This study aimed to calculate the bridge floor slab. With the quality of concrete used is FC'30 Mpa, the quality of steel used Fy = 400 Mpa. While field reinforcement (Positive Bending Rebar) is used D32 – 150 reinforcement, for him reinforcement is used D22 – 150. In fulcrum reinforcement (Negative Flexural Rebar) D32 – 150 reinforcement is used and reinforcement for D22 – 150. The total deflection on the bridge floor slab is 0.1668 mm. The shear strength is factored at 379.572 kN.

Abstract

Reinforced concrete structures cannot be separated from the use of reinforcing steel as a material that resists the tension that occurs in concrete structures. Specifically for buildings that require steel as reinforcement in new areas where reinforcement has not been installed, a chemical epoxy type of adhesive material is used, which is used in this study, namely Itewe Neo. Steel materials are used to carry out their duties to cover the weaknesses of concrete in terms of tensile loads, and chemical epoxy is used to connect two different materials, namely steel and concrete. The test is carried out to determine the magnitude of the difference in tensile strength of the tested reinforcing material. Experiments on steel with a minimum yield stress of 280 MPa, also known as plain reinforcing steel and reinforcing steel with a minimum yield stress of 420 MPa, also known as fin reinforcing steel. The variation used in this test lies in the diameter of the plain steel bars with diameters of 8, 10 and 12 mm. Fin reinforcing steel with diameters of 10, 13 and 16 mm. The test results show that the deeper the reinforcing steel, the greater the required tensile strength. Other results show that fin steel reinforcement has a greater tensile strength than plain steel reinforcement.

Abstract

Traditional houses are authentic historical-cultural heritage architecture and full of philosophy. One of them is the Karo Traditional House which is commonly called Siwaluh Jabu because it is inhabited by eight heads of families. Changes in human behavior due to the growing modernization process caused significant changes in the shape of the space in the Karo Traditional HouseThe change in the shape of the space in the karo traditional house occurs because there is no longer a desire to inhabit and build a traditional house due to friction of theft problems, social relations between families that are not in harmony, children cannot studied because of the noisy and crowded house conditions, and the interior completeness that is not possible. Some of these factors have resulted in a decrease in the concern of the Karo people for their traditional houses, which in the end there have been several changes in the spatial patterns of Karo traditional houses.The purpose of this study was to determine the shape of the space in the Karo traditional house in Lingga Village and the changed  in the shape and function of the space that occur in the Karo traditional house today. To achieve this goal, this research was carried out using a qualitative description method, where researchers made direct observations and conduct interviews with the local community. As a mandatory output of research, scientific articles will be published in nationally accredited journals.
