Abstract

The phenomenon of sleeping hours on student learning achievement is a topic that needs to be discussed because sleeping hours alone will affect the achievements achieved by students. humans are required to have enough hours of sleep. because one aspect of student success in achieving learning achievement one of the basic needs is needed enough hours of sleep. Sleep is a basic need needed by everyone. Everyone needs enough sleep so that the body can function normally. In the sleeping state, the body performs a recovery process to restore the body's stamina to optimal conditions, so that it can carry out normal activities the next day. Students or students also need sufficient rest time to maintain the stability of their health, insufficient sleep hours will affect the learning process which of course will also affect their learning achievement as well. Learning achievement is the result of measuring and assessing students or students during the study period at an educational institution. In this study, the population that we used was students from the Faculty of Communication Sciences and Multimedia, Mercubuana University, Yogyakarta, class of 2021, while the sample was the Faculty of Communication Sciences students themselves. This type of research is quantitative research. The instrument used in this study was a questionnaire on the influence of hours of sleep and learning achievement. The data obtained was then analyzed using the SPSS software. The results showed that the value of Sig. the deviation from linearity is 0.711 which indicates that the variable X and Y have a linear relationship. The coefficient of R squared on the results of the linear regression test is 0.051, which means that 5.1% of learning achievement can be explained by students' sleeping habits. So from the data analysis that has been done, it can be concluded that student sleeping hours have an influence on FIKOMM student achievement at Mercu Buana University, Yogyakarta.

Abstract

Salah satu inovasi yang dapat dibuat yaitu beton Self Compacting Concrete (SCC) yang dimana beton ini dapat memadat dengan sendirinya tanpa bantuan alat vibrator. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman air laut terhadap kuat beton Self Compacting Concrete dengan penambahan Fly Ash dan Visconcrete. Metode pengumpulan data yang didapatkan dari data primer yang dilaksanakan dengan membuat benda uji di laboratorium sesuai dengan standar yang telah ditentukan. Pengujian beton segar dilakukan dengan menggunakan alat V-funnel, L-ShapeBox, dan Slump flow, sedangkan pengujian kuat tekan dilakukan pada beton berumur 7, 28, dan 56 hari setelah direndam menggunakan air laut dan air tawar. Hasil dari penelitian ini yaitu kuat tekan tertinggi berada pada beton tanpa campuran Fly ash (FA 0%) sebesar 34-42 Mpa pada umur 7-56 hari, lalu beton dengan campuran Fly ash sebesar 55% memperoleh kuat tekan mencapai 37,96 Mpa yang direndam menggunakan air laut selama 56 hari, sedangkan beton yang direndam menggunakan air tawar berada padacampuran beton Fly ash sebesar 55% dengan kuat tekan mencapai 32,37 Mpa pada umur 56 hari.

Abstract

This research analyses the correlation between air temperature, road surface temperature and pavement temperature using the MPU 6050 accelerometer sensor and the Pearson correlation method. Temperature measurements were taken at several predetermined locations, with the data analysed to identify the correlation between the three types of temperature. The analysis showed a very strong correlation between air temperature and road surface temperature, with a correlation coefficient of 0.7845 at night and 0.9663 during the day. Similarly, there is a very strong correlation between road surface temperature and pavement temperature, with a correlation coefficient of 0.8482 at night and 0.9673 during the day. These findings indicate that an increase in road surface temperature leads to an increase in pavement temperature. It was concluded that the correlation method can be used to predict temperatures at other points without invasive direct measurements, thus preventing damage to the road due to destructive measurements. This method is recommended as an alternative in pavement temperature monitoring.

Abstract

In road network evaluations, road performance is assessed from structural and functional aspects. Typically, road surface roughness measurements rely on expensive, imported instruments. Therefore, this research developed a prototype roughness measuring tool using an ultrasonic sensor, which is more cost-effective. This study aims to calibrate the "Ultrasonic Surface Roughmeter" prototype and evaluate its accuracy in measuring the International Roughness Index (IRI) as a reference for road maintenance. The prototype was tested through calibration with the standard tool, Gap Man Working Profilometer. Data were collected from several road segments of a specified length, and measurement results were analyzed through descriptive statistics to compare data from both tools. The calibration results indicate that the prototype achieved a high accuracy level, with a correlation value of 99.51% and a confidence level of 97.05%. The Cronbach's alpha value of 1.0 shows excellent internal consistency, with an average measurement difference of approximately 3.11%.The "Ultrasonic Surface Roughmeter" prototype can serve as a valid and economical alternative for measuring road surface roughness

Abstract

Reliable road-roughness monitoring typically requires dedicated profilers, whose cost and operational complexity can limit repeated surveys. This study characterized the sensing chain of a vehicle-mounted Ultrasonic Surface Roughness Meter (USR) developed as a lower-cost alternative for International Roughness Index (IRI) data acquisition. The component evaluation included 15 ultrasonic distance tests under stationary and horizontal-motion conditions, 15 accelerometer tests referenced to 9.806 m/s², and GPS distance checks against roadway kilometer references and vehicle speedometer measurements. To strengthen the evaluation, the component results were re-expressed using error-based metrology metrics rather than relying solely on internal consistency statistics. The ultrasonic subsystem achieved a mean absolute error of 0.174 cm, an RMSE of 0.187 cm, and a mean absolute percentage error of 1.07% relative to ruler measurements; all reported relative errors were below 2%. The accelerometer subsystem achieved a mean absolute error of 0.0252 m/s², an RMSE of 0.0327 m/s², and a mean absolute percentage error of 0.257% relative to the 9.806 m/s² reference value, with the largest observed relative error of 0.75%. GPS distance evaluation showed confidence levels above 96%, with correlations of 99.84% against kilometer-point distance and 99.80% against speedometer-derived distance. These results indicate that the sensing chain provides a sufficiently stable measurement foundation for subsequent IRI computation and field validation while demonstrating that component-level accuracy should be assessed separately from end-to-end road-profile agreement.
