Abstract

Earthquakes are the biggest threat of natural disasters in Indonesia because they occur suddenly and attack densely populated areas, such as large cities. Earthquakes with a magnitude of about 5 or 6 on the Richter scale occur in almost all regions in Indonesia. If the force of the earthquake passes 7 on the Richter scale, it can cause a lot of damage. After the earthquake caused many fatalities, material losses, and others arising from this disaster. During this time after an earthquake natural disaster, residents have difficulty informing victims and damage to homes because by using a system that is still manual. Website design using waterfall method, the website will make it easier for the public to report information related to the number of victims of each family member, damage to the house and disbursement of funds if the data has been approved by the officer.  The results of the study, namely getting information related to damage due to earthquake disasters from the side of residents / victims.

Abstract

The need to get information in any form becomes important. Along with that, people who want to provide information are increasing day by day, both specific information (accessed for certain circles only) or general information systems (all people can access it). The problem is how to make an information system that can be accessed by android mobile phones faster and easier by beginners. An information system that can be accessed via Android phones is very practical and profitable because it can be accessed anywhere and anytime as long as you get an internet signal at that time. The difficulty in making an information system model like this is because many elements must be done, such as: installing some software, which takes time to learn from each of the built-in tools, providing a database, creating interfaces, and connecting the system to the cellphone. This study presents the result how to create an Android-based information system that is systematic and easy for beginners in the form of instructions for the steps of making a system which is equipped with a display capture of the installation activity results from several supporting software and is equipped with examples of the results of information system designs that have been successfully created. It is hoped that the results of this research can help make it easier to design an Android-based Information system application for beginners.

Abstract

Yogyakarta International Airport is a new airport but for aircraft mobility operational activities it is very crowded and crowded. Therefore, noise is often heard from the airport due to the mobilization of aircraft taking off and landing. The noise can interfere with health if it passes the predetermined quality standards. The purpose of the study was to determine the level of noise concentration, to determine the effect of wind speed and temperature on the noise level in the apron area of Yogyakarta International Airport. To find out the noise level and other parameters that can affect noise, the writer uses the independent and dependent variable method. The independent variables are the type of aircraft, the value of temperature/temperature and wind speed. The dependent variable in this study is the noise value generated from take off and landing activities in the airside area of the airport with units of db using a sound level meter. From the results of descriptive statistical analysis, the maximum noise value is 97.7 Db and the average noise value during landing and take off is 93,512 dB and 92.80 Db. This value is still below the quality standard based on the IATA (International Air Transportation Association) document and the Decree of the Minister of Transportation No. 48 of 2002 concerning the operation of public airports. And the parameter value of temperature/temperature is 0.231 and the value of wind speed parameter is 0.089. This value has been tested for normality if the value is above 0.05 then the results are acceptable. This means that it explains that the temperature and wind speed do not affect the noise level at Yogyakarta International Airport. The possibilities that can physically affect the noise level are the pressure and speed of sound.
