“…Dimana pada saat ingin melakukan pembangunan di lahan salah satu warga mengalami konflik antara masyarakat sekitar dengan pihak dari telkomsel itu sendiri. Akibatnya pembangunan tower tersebut cukup terhambat (Deng, 2021). Pihak Telkomsel mendirikan tower tersebut dengan sistem sewa lahan dan tentunya mengikuti prosedur perizinan yang ada (Lu, 2022).…”

Technological advances are currently growing rapidly, moreover the telecommunications sector is experiencing exponential growth. When they wanted to build a tower on one of the residents' lands, there was a slight obstacle, namely the occurrence of conflict in the community. Conflict is an event or social phenomenon that is part of the dynamics of human life. Often conflicts have a negative impact on conflicting parties such as the emergence of ongoing hostilities, material losses and even fatalities. Even so, conflict can also be a supporting aspect in a better survival. This can happen if the conflict can be managed properly and is able to take advantage of the conditions or background of the conflict which can unite the conflicting parties. In this article, the author seeks to make an effort to solve problems in conflict management in the form of mediation of conflicts that occurred in Talang Jambe, Palembang City, which involved the community, RT, and Telkomsel.

“…The spherical hinge stress state is affected by material selection and structural size. Moreover, it is closely related to the starting traction torque and stability of the swivel structure [1][2][3][4]. The swivel spherical hinge is typically composed of an upper rotary table, upper spherical hinge, lower spherical hinge, lower cushion cap, central pin shaft, and other structures, which bear the vertical load from the upper bridge structure.…”

The accurate analysis of key components of a spherical hinge structure directly affects bridge quality and safety during construction. Considering the key components of a spherical joint structure as the research object, a refined calculation model for the spherical joint is established to examine its stress using finite element analysis. The influence of design parameters on the mechanical characteristics of the spherical hinge structure is systematically analyzed. The response surface method (RSM), devised using a Box–Behnken design, is used to optimize the design of the spherical hinge structure parameters. A response surface model is established to derive the scheme of the optimized spherical hinge structure design. Moreover, by comparing the structural contact stress and rotational traction force before and after optimization, the effectiveness and necessity of the spherical hinge structure optimization are verified. The result comparison shows that the maximum contact stress and rotational traction force in the spherical hinge structure after optimization are reduced by 13.86% and 8.42%, respectively, compared with those before optimization. The relative error between the calculated and predicted values is approximately 3%, indicating that the RSM is feasible for optimizing key components of the spherical hinge structure. Its optimization effect is evident. Based on the identified optimal parameters of the spherical hinge structure, a range of recommended design parameters for the key structure of the rotating spherical hinge at different load carrying capacities is established using the interpolation method, which provides a valuable reference for engineering practice.

The steel box arch bridge in this study will be subjected to various temperature effects from the construction to the operation stage, including the cement hydration heat effect and the sunshine temperature effect caused by an ambient temperature change. Therefore, it is very important to control the temperature effect of steel box arch bridges. In this study, the newly built Dafeng River Bridge is selected as the steel box arch bridge. This study aims to investigate the temperature effect including hydration heat and the sunshine temperature effect of the construction process of a rigid frame-tied steel box arch bridge. The manuscript presents that the heat dissipation performance of concrete decreases with the increase in the thickness of a mass concrete structure. The average maximum temperature values of layer No. 3 are about 1.3, 1.2, and 1.1 times the average maximum temperature value of layer No. 1 for the mass concrete of the cushion cap, main pier and arch abutment, respectively. The higher the molding temperature is, the higher the maximum temperature by the hydration heat effect is. With each 5 °C increase in the molding temperature, the maximum temperature at the core area increases by about 4~5 °C for the mass concrete. The pipe cooling method is conducive to the hydration heat control effect of mass concrete. Based on the monitored temperature change and displacement change, the influences of daily temperature change on the steel lattice beam and arch rib are analyzed. A temperature rise will cause the structure to have a certain camber in the longitudinal direction, and the longitudinal or transverse displacement caused by the sunshine temperature change is no less than the vertical displacement. Due to the symmetrical construction on both sides of the river, the arch rib deformation on both sides presents symmetrical synchronous changes. Based on 84 h of continuous temperature monitoring on-site, the changing trends of the arch back temperature and ambient temperature are consistent and their difference is small during 1:00~4:00 in the morning, which is determined as the appropriate closure time for the newly built Dafeng River Bridge.
