APPLICATION OF DESIGN THINKING METHOD IN REDESIGNING THE UI/UX OF SIMAK (ACADEMIC INFORMATION SYSTEM) OF SRIWIJAYA UNIVERSITY BASED ON A MOBILE PLATFORM
No full textStudents at Sriwijaya University are having difficulty accessing academic information through SIMAK using their mobile devices due to a user interface that is not optimized for smartphones. In this study, the author used the Design Thinking method because it has stages that are very helpful in creating prototypes, such as the Empathize stage where the author can directly interact with users' personal opinions, up to the testing stage, which helps the author analyze the results of prototype creation so that further development can be more responsive and better. The prototype was tested through Maze, a platform that helps users test product or service prototypes quickly and efficiently. This platform is integrated with various prototype-making applications and allows users to collect qualitative and quantitative data in one place and the User Experience Questionnaire (UEQ) to analyze data from prototype testing. Based on the results of usability testing, the UEQ scores from 26 SIMAK users were above 1.6, with almost all assessment categories such as "Appeal", "Efficiency", "Accuracy", "Stimulation", "Novelty", and 1.3 in " Perspicuity". Therefore, it can be concluded that the SIMAK prototype design has a good user experience, and the design can be used as a reference for SIMAK mobile-based displays in the future

After agreeing the goods are purchased, the next question is how and where to buy. Similarly, after the goods purchased would be held accountable. The same process was also carried out in government procurement. Even more complicated and lengthy bureaucracy. Once the goods are purchased will also mean increasing the number of the country\u27s wealth. Next is to manage things as state property. The problem in this study was to determine the results of the internal control system before and after the implementation of SOA environment SIMAK Navy Banten. The author uses descriptive method of analysis that is by gathering evidence and information necessary for the other dat then processed and analyzed up to one conclusion. In addition, the authors also used the method of verification analysis is the analysis of the data by comparing the data according to the needs of the research. Population and the study sample were 30 personnel only, because in this case that did work activity directly related to the internal control system before and after penerapa accounting and management information systems property of the state (SIMAK BMN). The results of hypothesis in this study are very well influence the internal control system (SPI) before and after the implementation of management information systems and accounting property of the state (SIMAK BMN) in Banten Lanal operate. This means that there is a change between the variables before and after the application of SOA towards SIMAK very good. To determine the rate of change of the t value significant level (0231> 0.05
Penentuan arah kiblat menggunakan arah tenggelam bintang As-Simak (Arcturus) dalam kitab Tahrir Aqwa al-Adillah fi Tahsil ‘Ain al-Qiblah karya Syaikh Usman al-Betawi
No full textDidalam kitab Tahrir Aqwa al-adillah fi Tahsil ‘Ain al-Qiblah karya sayyid utsman bin yahya al-betawi untuk menentukan arah kiblat ada keunikan tersendiri. Dijelaskan di dalam kitab tersebut arah kblat daerah Jawa dan Melayu ialah menghadap ke arah tenggelamnya bintang as-Simak ar-Ramih atau biasa disebut dengan bintang Arcturus yang berada di rasi Bootes (Biduk). Kemunculan bintang ini sangat mudah diamati terutama di daerah Jawa dan Melayu karena letak bintang ini berada di deklinasi 19 derajat dari equator (khatulistiwa) serta nilai magnitude -0,05, menjadikan bintang ini bintang paling terang ke empat dilangit malam. Penulis di sini akan meneliti posisi bintang di arah tenggelamnya, karena menurut Sayyid Utsman bin yahya penentuan arah kiblat dengan bintang ini ialah menghadap ke kakbah secara ‘ainul ka’bah.
Penelitian yang dilakukan ini adalah penelitian lapangan (field research) yang termasuk ke dalam penelitian kualitatif numerik, dengan membandingkan hasil arah kiblat yang didapat dengan metode azimuth Matahari. Data primer penelitian adalah dari kitab Tahrir Aqwa al-adillah fi Tahsil ‘Ain al-Qiblah dan untuk memverifikasi menggunakan data yang didapat melalui observasi dan hasil data-data perhitungan dengan menggunakan azimuth arah tenggelam bintang as-Simak (Arcturus). Sedangkan data penunjangnya adalah aplikasi stellarium mobile untuk membantu penulis menjabarkan temuan di lapangan.
Hasil penelitian ini ditemukan bahwa as-Simak (Arcturus) dalam rasi Bootes dapat dipakai sebagai penentu arah kiblat. Arah kiblat hasil pengukuran dengan bintang as-Simak (Arcturus) cukup akurat, karena objek pembidikanya berupa satu titik pusat bintang.
ABSTRACT:
In the book Tahrir Aqwa al-adillah fi Tahsil 'Ain al-Qiblah by Sayyid Uthman bin Yahya al-Betawi to establish the direction of Qibla there has its own peculiarity. It is explained in the book that the kblat direction of the Javanese and Malay areas is towards the direction of the sinking of the star as-Simak ar-Ramih or generally called the star Arcturus which is in the Bootes constellation. The appearance of this star is quite easy to view, especially in the Java and Malay areas since the location of this star is at a declination of 19 degrees from the equator, a magnitude value of -0.05, making this star the fourth brightest star in the night sky. The author here will investigate the location of the star in the direction of its sinking, because according to Sayyid Uthman bin Yahya the determination of the direction of the Qibla with this star is facing the Ka'bah in a 'ainul ka'bah.
This research is a field research which is incorporated in a qualitative numerical analysis, by comparing the results of the Qibla direction obtained with the azimuth method of the Sun. The core data of the research is from the book of Tahrir Aqwa al-adillah fi Tahsil 'Ain al-Qiblah and to verify using the data obtained through observation and the findings of the calculating data using the azimuth direction of the sinking star as-Simak (Arcturus). While the supporting data is the Stellarium mobile application to enable the authors discuss the findings in the field.
The results of this investigation indicated that as-Simak (Arcturus) in the Bootes constellation can be used as a determinant of the Qibla direction. The Qibla direction measured using the star as-Simak (Arcturus) is quite accurate, because the targeting object is a single star center point
Six Legged Walking Robot Simulation and Control
No full textThe authors present the first results of their scientific work related to design and development of the walking robot control systems in virtual reality. Six-legged walking robot was created along with its virtual counterpart simulated in virtual environment. A control system was created and tested on virtual model. This control system was then directly used to control real robotic construction. Differences between real and virtual robot behavior were analyzed

No full textUsing Predictive Controller to Control a Nonlinear System
No full textThis paper engages in the Model Predictive Control of an Air Pressure system. The Air Pressure system includes a pneumatic and an electronic part. The model of the system was created using a tool for systems identifications. Since the system is nonlinear we can use the model linearization and set the constraints to create the Model Predictive Controller in MATLAB environment. The connectivity between PC and the air pressure system is realized by I/O card MF624. We provided the stability test as well. The PID controller was also designed to compare the results with those obtained from the Model Predictive Controller of the mentioned Air Pressure control system
