In applications, usability is an essential factor that shows the user experience whether the application is easy to use and fits its function or not. For this reason, this study aims to determine the usability of the registration module on the Khanza Hospital Management Information System (SIMRS) used by RSUD Banyuasin employees and to find out the difficulties faced, needs, and desires of RSUD Banyuasin employees as users of SIMRS Khanza. This research is helpful for the agency as a subject of application evaluation and helps discover what opportunities can be applied to overcome user difficulties. The approach used is Design Thinking. Meanwhile, the usability measurement uses the System Usability Scale (SUS) involving five respondents. The initial results of measuring the usability of SIMRS Khanza obtained were 26 with a poor rating. In addition, the interview results show that users have difficulty learning the application, the features and fields are too many, and there is a redundancy of patient data. Based on these findings, the researcher recommends a solution design with a High Fidelity Prototype (Hi-fi) with a final value of SUS 87. The implementation of this research recommendation can help the performance of RSUD Banyuasin with an application design that is easy to understand and supports the creation of accurate and consistent data.

Poverty in Indonesia has become a common thing that is still difficult to handle due to the presence of the covid virus outbreak attacks are causing the inability to buy and sell transactions, export and import goods and services, then the level of inequality increases. The tool measures the inequality level in an area seen from the Gini Ratio value. The Gini Ratio notes that the DI Yogyakarta province had the highest index value in Indonesia of 0,437 in September 2020. So this study aims to minimize the inequality in the DI Yogyakarta province by using the clustering method and Dynamic Location Quotient (DLQ). The clustering method with a hierarchical algorithm using the Dynamic Time Warping (DTW) distance and the DLQ method to predict regional economic sectors. Based on the result of the clustering analysis, there were 2 clusters, and the DLQ analysis obtained as many as 11 essential and 6 NPN-base sectors. Cluster 1 has 10 GRDP sectors with two industries that will become non-base sectors in the future, while cluster 2 has 7 GRDP sectors with three sectors it will become base sectors in the future.

This innovative door lock system is designed to make it easier to control security in certain homes or rooms. This system can also be used in government offices and factories to restrict someone from entering a room that just anyone can not enter. In this system, the automatic door lock uses an ID-12 type RFID reader, Tag/Transponder, Arduino UNO R3, 5v Buzzer, Drop Bolt Lock, Relay Module, and LCD. The RFID reader ID-12 is used as a receiver, and the tag/transponder as a transmitter. This system works when the scanned RFID tag/card/transponder sends hexadecimal data to the RFID Reader ID-12, which then, from the RFID Reader, will receive and send data to the Arduino. Then the Arduino UNO will process it by reading the program module (data from the RFID tag/card/transponder) and giving commands to the buzzer to make a sound or notification. The relay module is a connector or breaker for the deadbolt lock or solenoid to open and lock the door and a 16x2 LCD to display the status of the scanned RFID card. On standby, the LCD displays the words "Smart Door Lock Scan Your RFID." When the scanned RFID card is registered and the bolt lock or solenoid is open, the LCDs the words "Welcome". When the scanned RFID card is not registered, and the drop bolt lock or solenoid is not open, then the words "Your Card is Unregistered." The push button is used to reset the Arduino when the Arduino is hanging and when the 16x2 LCDs have an error display

The expression on the human face is a means of non-verbal communication. In the talent search event, the facial expressions shown by the judges when watching the participants' performances became one of the components to see whether the contestant who was performing could qualify for the next round or he would fail. Haar cascade is used to provide the location of the face in the frame and to classify the expressions on the face, a CNN model with modified AlexNet architecture is used which increases the accuracy by 5% from the original alexnet. A fuzzy Algorithm is used to predict the judge's decision based on how many facial expressions appear during the participant's appearance. The decision prediction system for talent search judges based on facial expressions using fuzzy is considered effective in predicting decisions, after being tested the system can predict decisions with an accuracy rate of 83%.

A museum is an institution intended for the general public that collects, cares for, presents, and preserves the community's cultural heritage for study, research, and pleasure or entertainment. The museum is undoubtedly one of the educational places for the community because it has many historical objects. It provides an opportunity to make the museum a vital place to be developed in a virtual form, such as Augmented Reality or Virtual Reality. However, one problem in developing virtual media is the 3D modeling of objects for interior design in museums. LiDAR (Light Detection And Ranging) is a near real-time 3D positioning technology. A point cloud collects data points in a 3D coordinate system, generally defined by x, y, and z coordinates. Both of these technologies can be used to create 3D object models quickly. The final result of this research is applying LiDAR & point cloud as a 3D modeling technique and assessing the accuracy of using these techniques for 3D modeling of the museum object

In late December 2019 it took the world by storm by transmitting very quickly through the human respiratory tract. Since this happened the World Health Organization (WHO) has stated that Covid-19 is called a pandemic. The Covid-19 outbreak affects almost all aspects of life, including the aspect of education in Indonesia, which is also not spared from the Covid-19 outbreak and also feels the consequences of the spread of the virus. Students feel the impact of the spread of Covid-19 such as changes in the provision of services in educational institutions, such as formal education at all levels, non-formal education, to academics (Baety and Munandar 2021). Based on the announcement of the Ministry of Education and Culture Number 4 of 2020 concerning the Implementation of Education Policies during the Emergency Period of the Spread of the Coronavirus (Covid-19). The government began to implement an online learning system (online). The problem that arises during this online learning period is that there are still many people who are not ready to face technology, both in terms of teachers and students, this happened in the early days of the pandemic. So that the learning process that has been carried out normally, both in terms of teaching and providing assessments, also experiences obstacles. This is because the teaching staff (teachers) always have daily assessment data that is usually carried out daily during normal learning. However, during this PJJ period, teachers became confused about giving daily assessments to their students. The purpose of the research is to analyze and evaluate the online learning system using a platform that is easy to operate by teachers and can be accessed anywhere, namely, google form. In the Google Form application, there is an automatic calculation system in the form of student feedback where teachers do not bother to manually calculate the results of student learning evaluations (Munawaroh, Prastowo, and Nurjanah 2021). The analysis method used is the Technology Acceptance Model (TAM) which is able to find out the attitudes of users towards the technology used, so that teachers can easily find out whether the tasks given to students are done by the students themselves, not the help of parents.
