Abstract

Regional General Hospital is a health service institution owned by the local government. The services provided by hospitals are required to always make changes, so that the services can be in accordance with the expectations and needs of the community. Hospitals as one of the institutions that have the function of providing health services must of course be in accordance with predetermined standards. Regarding improving the quality of hospital services, the government as the main actor who plays a direct role both to be responsible and to plan, regulate, organize, foster, and supervise the implementation of improving the quality of health in this case through several public policy products has explicitly discussed and regulated everything related to achieving this. Based on the needs of hospitals in assessing public sentiment as an important point in the accreditation process of hospitals, it is necessary to analyze the sentiments of public opinion towards hospitals. To perform sentiment analysis, the method used in this research is Support Vector Machine and word weighting uses Term Frequency-Inverse Document Frequency. Testing using Cross Validation with 132 training data and 33 test data resulted in an accuracy value of 88% and recall of 87.5%, precision of 90% and f-measure of 87.5%. This value is obtained when using the parameters C=1 and Itermax=1000.

Abstract

Learning is the main activity in the whole educational process in schools. Because learning is done at home (online), the success of learning will be disrupted, especially in the aspects of learning motivation, technological literacy, and collaboration between students. The purpose of this study is to compare aspects of learning motivation, technological literacy, and student collaboration when they are still doing face-to-face learning, compared to online learning. This study used descriptive qualitative method. Interviews with students and teachers relate to these three aspects. Then the analysis technique uses the Miles and Huberman method, namely collecting data, reducing research data, and presenting data. Based on the results of interviews that have been conducted, there are several keywords that appear in the research. Among them are limited internet quota, and also network problems. The conclusion in this study is that most students at SMK Negeri 12 Malang feel they tend to experience a decrease in learning motivation in terms of attendance and doing assignments, compared to when they were still in school face to face. Then for technological literacy, most students admitted that they only knew about learning applications when distance learning took place and not a few had difficulties in operating. Meanwhile, in the aspect of collaboration between students, most of the students admitted that they had difficulty communicating with other students.

Abstract

Pregnant women need to increase their knowledge to find out how big the level of risk of getting a disease, especially because of the vulnerability of pregnant women. Classification of the level of disease risk in pregnant women is expected to assist users in finding the right solution to overcome it. The classification method used to determine the level of disease risk for pregnant women uses Modified K-Nearest Neighbor (MKNN). Classification of disease risk levels in pregnant women using the Modified K-Nearest Neighbor (MKNN) method can make it easier to detect disease based on existing factors. The Modified K-Nearest Neighbor (MKNN) method is implemented on the expert system inference engine so that conclusions can be drawn based on existing knowledge. The results of the accuracy of the system obtained after testing is 85% which indicates that the Modified K¬-Nearest Neighbor (MKNN) method is suitable for studying the level of disease risk in pregnant women.

Abstract

Wireless Sensor Network (WSN) is a network formed by several sensor nodes and wirelessly connected to each other with the limitations of each node. One of the limitations of the resources contained in the WSN node is the communication media. This causes WSN to require a data communication method with low resource usage. The nRF24L01 module is designed of being implemented in a wireless network that has low resources, so that it can be applied to a WSN network. The nRF24L01 module will broadcast or broadcast at an address to transmit data. Then, to receive data, a listen process is carried out so that it can be received by devices that are at the same address as the sender. This causes a security hole when a device is intended to send data to the desired device only. For this reason it is necessary to have a mechanism that can ensure the security of ongoing data communications. The SPECK algorithm has been tested on both hardware and software by the National Security Agency (NSA). The SPECK algorithm has been optimized to run on the software. Users can implement SPECK Cipher by considering the application and hardware required without compromising performance. The purpose of the SPECK algorithm itself is to provide the flexibility and performance characteristics required by developers. The implementation of the SPECK algorithm on the system makes this system resistant to both passive and active attacks.

Abstract

The development of Moodle e-learning utilizing cloud computing services is increasingly popular where the cloud offers a pay-as-you-go resource rental system. Amazon web service (AWS) offers features and services such as AWS EC2 virtual private servers and AWS RDS services as database services for building Moodle services. However, due to the nature of cloud services, namely “pay-as-you-go” or pay according to resource usage, performance is key. To find out the performance of a number of resources that are built, it is necessary to design the resources to be used, looking at the performance aspect compared to the estimated costs that will be incurred as a consideration for resource selection decisions to build Moodle services. Testing and evaluating performance on multiple EC2 resource clusters and single RDS databases and read-replica databases via 50, 100, and 200 tiered HTTP requests on Moodle activities such as Login, Course, Forum, and Quiz to get results on CPU, RAM, and Throughput usage and Latency using Apache JMeter and System Activity Report (SAR). The system test results show that there is an increasing trend along with the increase in requests from clients to servers. View activities such as Login and Course require faster processing time than Forum and Quiz. To calculate the Performance-to-Cost Ratio, the EC2 t2.small and RDS db.t2.small clusters are superior from the aspect of Throughput to cost ratio of 0.23 requests/second per dollar.

Abstract

The development of information technology today has affected all aspects of human life. There is an exchange of information every second on the internet. RESTfull API / REST API describes the embodiment of the API (application protocol interface). The REST API has a weakness in terms of security standardization for accessing data on the REST server side, this causes anyone to access, edit and delete the data contained in the REST server.MD5 is a type of Cryptographically secure hashing which has a one-way hash function. MD5 is often used to store passwords, if the cracker is able to enter and change a secret website database and then the cracker performs attacks such as SQL Injection, DDOS so that it penetrates the database and gets the password in the form of an MD5 encrypted hash then it is easy to decrypt it into plaintext to get the password. which are actually.The BLAKE2S algorithm itself was released in 2012. The BLAKE2S algorithm is built with the HAIFA iteration which has resistance to generic attacks such as herding. The BLAKE2S algorithm has a better security level than SHA-256. This research implements the BLAKE2S Algorithm for the key value caching mechanism in the REST API. The test was conducted to measure the speed of the BLAKE2S Algorithm in processing key value caching. Testing is done by running a request on the REST API twelve times to measure the caching time. The test results show that the caching time on the BLAKE2S Algorithm has a faster time than the MD5 Algorithm with a time difference of 5.6 ms.

Abstract

MSMEs are one of the drivers of the economy in Indonesia. MSMEs are the largest business units in Indonesia with a number reaching 99.9% of the total business fields (Santia, 2020). The development of MSMEs must include improvements in all aspects again in terms of sales. This increase can be achieved by digitizing MSMEs. Through the digitization process, MSMEs can optimize the opportunities and opportunities that exist because the targets that can be achieved are wider. This research is a research related to the process of optimizing MSMEs digitally. The digitization of MSMEs in this study was carried out by designing an e-MSME system. E-MSME is a system design that can help MSMEs in marketing their products. This marketing is done by providing a marketplace for MSMEs and consumers. So that consumers can find the product they are looking for according to their needs. This study uses a prototype model method that comes from the design process, using modeling using UML (Unified Modeling Language). Data collection in this research process is using data from three resource persons who are engaged in MSMEs. The next process after UML modeling is prototype design using the Figma platform. The finished prototype is then returned so that the repair process can be carried out. The results obtained from this study are the system has obtained "good" and "acceptable" results.

Abstract

CV Indomedia Pustaka was established as a company with a focus on book publishing. In running the business process CV. Indomedia Pustaka has problems with the inconsistency of the completion time for each book to be published. This will pose a risk to the CV publisher. Indomedia Pustaka. To be able to help solve problems, the first thing that needs to be done is to identify business processes in detail to be able to solve existing problems. There are four steps in the identification process: breakdown, modeling with Business Process Model and Notation, fine tuning, and validation (BPMN). Value Added Assessment (VAA) and fishbone diagrams were used to analyze the problem. Simplification is the third step of Business Process Improvement (BPI), and it is determined that six business processes need to be improved. As an additional step, the proposed business process is put through a bizagi modeler simulation comparison to see how much time can be saved by implementing it than the current one. On the recommendation of the manuscript checking business process, an increase of 42.95% was carried out. Recommendations for editing manuscripts also increased by 33.24%. The script layout business process has increased by 3.37%. The recommendation for book cover design decreased by 9.11%. However, the recommendation for author approval experienced a significant increase of 49.95% and the recommended production business process also increased by 8.76%.
