Abstract

One of the sport that is often played by the general public is futsal where is the futsal follows the basics of football, but the difference with football is that futsal is played by a few people and is played on a relatively smaller place or field. In every futsal game, of course there must be a player who suffered an injury. Slippery and uneven field conditions are the factors that affect futsal players that can easily fall and subsequently suffer injuries during futsal games. The existence of a system that can classify the types of injuries suffered by futsal players will greatly help solve this problem. Utilizing the modified k - nearest neighbor method implemented using Java language, a maximum accuracy of 97% is obtained from different K values.

Abstract

Currently the face-to-face learning process can no longer be carried out due to the 2019 coronavirus disease (covid-19) pandemic which has spread in Indonesia. The spread of Covid-19 has a major impact, especially on the education sector. The temporary closure of educational institutions is an effort to contain the spread of the Covid-19 pandemic. Teachers at SMP Negeri 1 Merek also experienced the same thing, most of whom were unfamiliar with the use of technology. Habits in the face-to-face learning process make teachers experience many obstacles in teaching online. Some teachers when they try to use technology for the first time are successful, but they forget to repeat the same thing on a different day. This descriptive study is expected to produce an explanation of the results of the analysis based on the exploration carried out. Exploration is carried out by means of interviews to explore teacher experiences during the online distance learning process. The results of the interviews with seven resource persons were then made transcripts and analyzed by thematic coding, in order to obtain the appropriate theme / categorization. It is hoped that this research will produce documentation that can be used to find out what was experienced by the teachers and what technology was used during the online distance learning process. Based on the research that has been done, teachers at SMP Negeri 1 Merek use whatsapp and classroom applications.

Abstract

Indonesian is a country where a third of its population works from the agricultural sector, especially rice fields. Most farmers expect maximum yields without knowing the soil fertility with the factors that support this fertility. Factors such as soil pH, soil moisture, soil temperature and various other factors. Especially the factors can also change at any time that could interfere with the process of plant growth if farmers do not pay attention to these changes. With the developing technology, we can make it easier to monitor soil pH, soil moisture and soil temperature using the YL-69, DS18B20 and soil pH meter sensors. The data taken by the three sensors will be accommodated in the sensor node and then sent to the gateway via the websocket and forwarded to firebase and then displayed to the web interface. Testing is done using quality of service to determine the performance of the network performance from delivery speed, packet lost during delivery, and time interval of each delivery. Then the performance test results obtained, namely the throughput of H-1 to H-3 is 12.11 bps, 10.88 bps, and 16.13 bps. Packet loss from H-1 to H-3 is 0.4%, 0.3%, and 0.2%. The delay from H-1 to H-3 is 0.12 s, 0.09 s, and 0.09 s. The tool's function test works successfully with data taken from the three sensors that can be displayed on the web interface.

Abstract

Services at the Regional General Hospital Sidikalang even now rely on conventional medical records or manual system. The patient's data then would be recorded in one or more medical records and this condition has been a weakness of conventional medical records whenever data sharing is required. These weaknesses of conventional medical records affect work efficiency at Sidikalang Hospital and finally leads to hospital accreditation that currently holds class C. A web-based patient medical record management system is necessary to overcome this problem. This management system will help medical personnel in data sharing, data maintenance and make it easier to locate it. This system's development was carried out using the waterfall software development model and object-oriented approach. This system was tested using unit, integration, and validation testing strategies. White box testing technique was applied when performing unit and integration tests. Black box testing technique was utilized when conducting validation testing. The result of this research was a web-based patient medical record management system.

Abstract

Doreni Petshop is a pet shop in Malang that sells pet supplies and offers coat facilities such as grooming and day care. However, there are several problems in its management, such as problems in recording, because grooming and storage orders as well as sales orders and out-of-stock orders so that employees often make mistakes in recording them. There is no record of incoming stock and frequent records of sales and purchases that have not been recorded in the orders are lost, resulting in different calculations for expenses, entries and stocks. As for customers, those who want to get a service function must order a slot on h-1. Usually, customers who did not place an order had to go home because they ran out of slots. Based on these problems, researchers developed an ordering system so that customers can order available packages without fear of running out of stock and developed a management system with the principle of point of sale that can manage orders, manage stock availability in and out, manage package availability, manage sales transactions, manage order and sales history, can print receipts and use qr-code to simplify the process of selling goods. The system is built based a on website with the SDLC model waterfall. Implementation with the programming language PHP and javascript using the codeigniter framework by applying the MVC concept. The test results in 100% valid status on unit testing, integration, and validation. Testing compatibility using sortsite results that the system is able to run in different browsers.

Abstract

Blockchain is a database system that has a decentralized architecture, where every data contained in the blockchain system is spread across all peers that are connected in the blockchain system. One of the most discussed blockchain uses is cryptocurrency, which was coined by Bitcoin. In the hashing process on the blockchain system used by Bitcoin using the SHA-256 algorithm, a weakness has been found of the SHA-256 algorithm, namely the preimage attack using the biclique concept on the compression function owned by SHA-256. This is what underlies the author to implement blockchain in peer-to-peer transactions using the U-Quark algorithm. The author uses the U-Quark algorithm because the architecture owned by the Quark Family hashing uses a combination of block ciphers and stream ciphers owned by Katan and Grain for permutations and uses Sponge Construction as its constructor. There are 3 factors tested in this study, namely test vectors, functional, and availability. In vector testing, the resulting digest value is the same between the implemented U-Quark algorithm and the digest value that has been determined in the hashing family Quark. In functional testing using the blackbox method with 100% valid results. The Availability tester generates the same data in every peer available in the blockchain system. The U-Quark algorithm consists of 3 stages, namely the initialization phase, the absorbing phase, the squeezing phase, and the blockchain system built involves 2 types of systems, namely the blockchain system and the wallet system. The blockchain system functions as a storage system and a wallet system as a place to enter transactions into the blockchain system.

Abstract

Inventory is one of the important things for institutions to support various kinds of needs. One of the institutions that cannot be separated from inventory is schools. There are so many items in school that it is necessary to have better inventory management to manage these items so that these items can be used properly. However, this can cause various problems if management is still conventional, data items can be lost, damaged, and mismatch data between one data and another. Therefore, an inventory management system was created so that can use make it easier to manage inventory. System is built in website platform using ReactJs and Redux, and programming language is javascript, html, and css. Database system using firebase. System development life cycle using RAD (Rapid Application Development), this methodology has been choosen because the design work process involves the user, so the results obtained are in accordance with the users hope. Functional testing in this research uses whitebox testing and blackbox testing. Non-functional testing uses compatibility testing and security testing. The results of functional testing using blackbox and whitebox testing are 100% valid and the results of non-functional testing which is security testing is 100% valid while the results of compatibility testing are only be run on certain versions of the browsers.

Abstract

Mobile JKN is an e-government application that is used by the government as an innovative use of information and communication technology in government administration. Mobile JKN is an application as part of BPJS Kesehatan's commitment in providing services and easy access for BPJS Kesehatan users. Indonesians can try using the Mobile JKN application and review it on application providers such as the Google Play Store and the App Store. Reviews as a way of expressing opinions, offer data sources in the form of user sentiments regarding the features and services available on the Mobile JKN application. Sentiment analysis research is conducted to analyze the sentiments contained in user reviews by classifying reviews as positive or negative. In this research, Maximum Entropy is used as a classification method with Mutual Information as a feature selection to reduce the number of features used in the classification of user reviews of the Mobile JKN application. In testing, better evaluation results are shown by the use of the Mutual Information feature selection in the classification using Maximum Entropy with an accuracy value obtained of 82.5% compared to without the use of feature selection which results in an accuracy of 79.5%.

Abstract

Based on a basic health study conducted by the Ministry of Health in 2018, 9-10 out of every 100 Indonesians suffer from mental and emotional disorders. A significant increase compared to 2013 data, namely 6%. Despite the high incidence of sufferers, there is a large imbalance between the number of mental health cases and the availability of mental health professionals in lower middle income (L-MIC) countries, including Indonesia. In addition, the price of consulting professionals is quite high, especially for adolescents. From these problems, there is an alternative solution, namely internet-based intervention. Cybercounseling or what is often called E-counseling (electronic counseling) is one of the guidance and counseling services using computer technology, especially the internet. This research will develop an e-counseling application as a preventive action and treatment for anxiety disorders. The method used in this research is Personal Extreme Programming. The research started from the requirements engineering stage which resulted in 32 functional requirements and 1 non-functional requirement. The implementation stage of this application uses Firebase as a database and using the Kotlin programming language. The final stage is a testing phase with unit testing resulting in 3 functional tests that are valid, validation testing has succeeded in reaching 100% valid according to the expected result, and usability testing produces a usability score of 87 on Maze and a SUS score of 71.5. From this research, it is hoped that it can help provide preventive action and treatment of symptoms of anxiety disorders, overcome difficulties in finding information on mental health services, provide convenience in conducting counseling, educate the importance of mental health, and helping people seek help during emergencies.
