Calibration of Geomagnetic and Soil Temperatur Sensor for Earthquake Early Warning System
No full textThe study of Design of Earthquake Early Warning System for Real Time Using Geomagnetism and Total Electron Content with Fuzzy Logic through competitive grants scheme has obtained the prototype of the earthquake early warning system. However, it still needs improvements on in the calibration of thesensor system especially for MAG3110 sensor and DHT11 sensor. This calibration was done by adjusting the sensor system to the existing measuring devices standards in the Physics Department laboratory of the Sains Faculty Lampung University, to obtain measurement accuracyand to get a good result about where and when the earthquake would occurand how strong the earthquake would be. The calibration of MAG3110 sensor and DHT11 sensor obtained the standard correction results, the standard deviation of MAG3110 from 3 axes, namely x axis was 8.5, y axis was 2.66, and z axis was 1.9, whereas the standard deviation for DH11 sensor was 0.1161
STREET ART: SISI LAIN DARI FENOMENA MURAL JOGJA SEBUAH PERTARUNGAN IDENTITAS DAN KEPENTINGAN
No full textMurals, as one o f the public art genres, has experienced rapid development in Jogjakarta, especiallysince the emergence o f Kclompok Ajwtik Komik as one o f its pioneers. Nevertheless, there are other factorsinfluencing the development o f murals, including socioculture, politics and economics, as well as globaldevelopment: lifestyle and the globalisation o f culture. The project o f Apotik Komik (Mural Kota, 2002)marked the beginning o f murals. As a result, murals spread sporadically throughout Jogja and even reachedremote corners o f the city. A new moniker is even attached to jogja as the City o f Murals.'The term "mural" (especially amongst the people o f Jogja) becomes a common word used to addressevery drawing and painting on most ivalls across the city. While, in fact, some works on walls in Jogjaoriginate from different genres. Several works are inclined towards the artistic style and possess roots whichare different front existing murals; some choose gruff ti and street art such as stencil, sticker, characters, etc.Differing from former mural artist communities, in the beginning o f2003 these groups began lo show theiractivities in Jogja s public spaces, and, o f course, they have different characteristics from existing murals.Keywords: street art, graffiti, public spac
ANALISIS KEPUASAN PERSPEKTIF KUALIAS PELAYANAN
No full textThe main business of a bank is trust. Therefore, all efforts are made to serve, and satisfy customers, one of which presents quality service. This study aims to analyze the effect of service quality on customer satisfaction. To prove this research, the quantitative, descriptive, and linear regression analysis methods are used. The object of research is Eximbank, sampling technique using accidental sampling, the number of respondents 109, and data collection techniques using questionnaire. The results showed that service quality affected satisfaction. That is, customer loyalty depends on what consumers feel, and quality service is the best way to approac

PERFORMANCE OF THE ACCURACY OF FORECASTING THE CONSUMER PRICE INDEX USING THE GARCH AND ANN METHODS
No full textThe Consumer Price Index (CPI) is the most widely used indicator of the inflation rate. Then, the value of CPI in the future must be known to be the basis of the government's making appropriate and accurate policies. The CPI data used in this study was taken from the Central Statistics Agency (BPS) from January 2006 - to December 2021. The CPI data used has a data pattern containing symptoms of heteroskedasticity. To overcome the symptoms of heteroskedasticity, the author uses the GARCH and ANN methods to determine the value of CPI in the future. The GARCH method can overcome the symptoms of heteroskedasticity in the time series forecasting process, while ANN is an effective method in time series forecasting because of its high level of accuracy. In this study, mape error calculation results were obtained with the ARIMA model (4,2,2)~GARCH(1.1) of 3.19% or with an accuracy of 96.81%, and ANN using two hidden layers of 1.24% or with an accuracy of 98.76%. Thus, the results of this study show that the ANN method is the best method of forecasting Consumer Price Index (CPI) data
