Abstract

Structural design is an important element in the construction of a building in order to produce a building that is strong, safe and economical. The overall structure of the building consists of two parts, namely the upper structure in the form of floors, beams, columns, walls and roof while the lower structure is in the form of a foundation. The DPRD building for the city of Bukit Tinggi will be analyzed using the Special Moment Resisting Frame Structure (SRPMK) system based on the procedure for calculating reinforced concrete structures using (SNI 2847-2019). Earthquake load analysis uses the spectrum response method based on earthquake resistance planning procedures for building and non-building structures using (SNI 1726-2019). Analysis of minimum design loads and related criteria for buildings and other structures using (SNI 1726-2020). Modeling in this study uses software based on 3D finite elements using SAP2000. The results of this study explain that the modeling meets the requirements for SNI-1726-2019 earthquake design and SNI 03-2847-2019 reinforced concrete design.

Abstract

In the Hexacopter flight control system, there are three very influential movements, namely Pitch, Roll and Yaw movements. Roll movement is very important to note because it affects the direction of the plane's flight. This movement is strongly influenced by the system's dynamic response to changes in hardware characteristics and the influence of changes in wind direction and speed from external systems. For this reason, this research is offered to implement a control system that can adapt to these dynamic disturbances. This study proposes the application of a proportional integral derivative (PID) control system, where constant values can adjust to dynamic changes in the system. These constant values can adjust to changes in errors and delta errors at any time. then a fuzzy logic controller (FLC) algorithm is applied, to make the constant values adaptable. The design of Fuzzification and Defuzzification is based on the maximum error and delta error limits. After real-plant testing, system performance is obtained as follows: settling time = 24mS; peak time 21mS; rise time = 9mS; delay time = 4.4mS; percent overshoot and steady state error = 1%.

Abstract

Starting with COVID19, almost everyone around the world uses the internet, even to the worrying stage, namely internet addiction. Several studies report that the level of addiction to using the internet network is getting higher even though COVID19 has subsided. Teenagers have not been able to choose useful internet connection activities and they are more prone to experiencing bad influences from the social environment. To overcome this they need support from psychologists so they can prevent and diagnose early before they become sufferers of severe internet addiction. But on the other hand, the number of psychologists who can help is still very limited, especially in small towns. In addition, economic factors and limited time for parents to accompany their children to visit psychologists are the main obstacles. Therefore it is necessary to find a solution that can overcome the limitations and barriers to adolescents in obtaining services from a psychologist. One solution to this problem is to build an expert system that can work as a psychologist. The purpose of this research is to build an expert system application for diagnosing internet addiction using the backward chaining method. Internet addiction level is categorized in low, medium and high. System testing is carried out using black box testing which allows experts to obtain a set of output conditions that will carry out all functional requirements of the program. This test shows that the inout and output data has been running as expected.

Abstract

In terms of improving road pavement, there are several things that must be paid attention to, namely the quality of the aggregate used, the method of implementation, and the quality of the asphalt. The method that is often used to improve the quality of asphalt is by adding additives. These include charcoal, plastic, and others. Plastic has many benefits but also has negative sides, especially plastic waste. However, plastic waste opens up opportunities to be used in the field of road construction. In research, mica plastic can be used because it has characteristics that are stronger than other types of plastic and more elastic when heated. Mica plastic is thermoplastic, not reactive at room temperature, except for certain types of solvents which can cause damage. In this research the author tries to determine the effect of adding mica plastic and determine the aggregate gradation characteristics of the Asphalt Concrete Wearing Course (AC-WC) mixture based on the Marshall test. The results of this test show that all experiments with the addition of mixing carried out for the addition of 0% mica plastic obtained an optimum asphalt content of 5.50%, with an addition of 2% the optimum asphalt content was 5.50%, with the addition of mica plastic as much as 5.50%. 4% cannot be used because the test results do not meet specifications, whereas with the addition of 6% mica plastic, the optimum asphalt content value is 6.25%. So, the best effect of adding mica plastic to hot asphalt (AC-WC) is mixing plastic levels of 0% and 2% with the optimum asphalt content obtained at 5.50%. For the Stability, Flow, VMA, and VFB values, the average results meet the specified specifications, while for the MQ and VIM values, the values ​​increase and decrease at each specified percent, thus affecting the results and performance of the asphalt used. So, it can be concluded that adding mica plastic to the asphalt mixture cannot be used, further research is needed to get more accurate results.
