Many things that have experienced technological advancements are one of which is the continued development of software. One example of software development today is the Matlab software. Matlab is currently able to be used to predict and analyze an existing problem. A lot of research has been done with the use of matlab software. Artificial Neural Network (ANN) is one of the command languages used in the matlab program which is used to predict the data entered. Besides that, Bengkulu Province is one of the earthquake and tsunami prone areas in Indonesia. This is because Bengkulu is in the subduction zone (collision) of active plate encounters in Indonesia Australia and Eurasia. Recording earthquake data must be recorded properly because this earthquake data will often be used, both for development and for the environment. The ANN method uses trial epoch until the smallest error is obtained. The smallest error results stopped at the Epoch 2000 trial. The Epoch 2000 trial produced the biggest error of 59.1% and the smallest error of 2.93%. The results of this study, obtained ANN is quite capable of calculating earthquake data predictions in the province of Bengkulu in 2018.

The structure of a simple rental apartment building of the Sumatran Technology Institute had been modeled using the Performance Based Design method. The aim of this study was to obtain the base shear and maximum displacement as well as the performance level of the building structure models in resisting the combination of gravitation and lateral earthquake loads. The loads were based on the function and location of the building. The building structures had been designed as a double system, namely the beam-column frames and shear walls in the direction of the XZ and YZ axis. There were four models: the models with a double system according to the original design, the beam-column frames without XZ shear walls, the beam-column frames without YZ shear walls, and the beam-column frames without shear walls. The results of the analysis at the performance level showed that the model with a double system was able to resist the highest base shear while the frames system without shear walls was only able to resist the lowest base shear compared to other models. The inter story drift under earthquake loads in the direction of the X and Y axis showed that all models of structural system were still within the safe limit.

Pavement has become important to people mobility in Indonesia, especially in urban areas. Vehicle mobilization will experience less obstacles if the road pavement conditions are in good quality. At the moment, additives, fillers or road material substitutes are quite expensive and are limited, therefore, research needs to be carried out to find materials which can improve the quality of pavement such as increasing its resistance or stability and flow. The purpose of this study was to analyze the benefits of using wall fragments as the fillers in asphalt concrete wearing course. The effect of using wall fragments as a substitute for rock ash on the value of Marshall parameters is studied, as well as the various levels of wall fragments addition that can produce the greatest stability. In this study, four levels of wall fragments were used as fillers: 0%, 25%, 50% and 100%. Based on the results analysis, it was concluded that the use of wall fragments as fillers in asphalt concrete can increase the following parameters: VMA, VIM, stability, and flow, but it reduces the VFB value. In addition, the use of 25% levels of wall fragments in asphalt concrete produces the greatest stability value, which is 1622.47 kg.
