Abstract

Indonesia is a country that consists of many islands and has a diversity of tribes that are scattered throughout its archipelago. Diverse ethnicities, various characteristics are also owned in order to distinguish one tribe from another. One of the distinguishing characteristics is batik, which is widely known and has become a cultural heritage. When viewed from the picture, the batik pattern has a texture. In digital image processing, texture can be used as an element that differentiates batik from one another, one of which is the Local Binary Pattern (LBP) method. By using the Local Binary Pattern (LBP) method, the texture of batik will be recognized as a feature of digital image processing, the batik image can be processed to obtain several similar images. The research process on batik begins with pre-processing, then extraction of texture features in the image using the Local Binary Pattern (LBP) method and continues with classification by K-Nearest Neighbor (KNN). In this study was using the normalized LBP value. At normalized values, the best results are using K-Nearest Neighbor with neighbors (K) = 5 by getting an accuracy of 65%

Abstract

Ambulan Online is a mobile-based application for tracking the location of the ambulance which is expected to increase response time by getting the nearest ambulance position. In the process of using it, there is data transmission from the application to the server. The data is sent in plain text which is a weakness for patient data security. Even though there are regulations regarding the confidentiality of medical records which are regulated in the Regulation of the Minister of Health Number 269 of 2008 concerning Medical Records. Based on this, the author will implement the Grain Algorithm and SHA-3 as encryption on patient data, location data and patient information. After that, conduct testing using a test vector to ensure the Grain Algorithm and SHA-3 used matching with the creator's property. To test the travel time of data on the entire system, researcher using data processing test by input 30 times data in that experiment. In this test, the average data processing time from the time the application user delivers the patient to the patient data entry is 5.6 seconds. Third is integrity test are carried out by checking the results of hashing data on SHA-3. Finally, researcher testing the key generation scheme to ensure key generation can function properly. The conclusion is that there is a difference in travel time after the Grain and SHA-3 Algorithm is implemented, but the patient data integrity aspect is met with the results of the integrity testing that has been carried out.

Abstract

Stress is the result of an unusual situation, with factors such as good or bad events, frustration, pressure, and environmental conditions causing stress. Stress can affect the condition of the body, and if a person experiences it, the body's reactions include excessive sweating, shaking, an increase in heart rate, rapid breathing, and headaches. Stress will be detected earlier and treated more effectively. As a result, we require a practical stress detector that is simple to use and can determine a person's condition based on his heart rate and body temperature. This stress detector uses two parameters: heart rate, which is detected by the MAX30102 sensor, and body temperature, which is measured by the MLX90614 sensor and processed by the Arduino Nano. The outcome of developing a tool with both sensors detecting via the fingers displayed on the OLED 0.96 inch and the accurarcy of the measurement between MLX90614 and thermometer is 98.51%, the measurement between MAX30102 and pulse oximeter got 92.43% accuracy and the overall test of the tool that has mad comparisons with DASS 42 stress scale got 70% accuracy using 10 subjects. The average computations time when a person detected as stress is 0.359 seconds.

Abstract

PT. Kencana Tiara Gemilang is a manufacturing company based on plastic sector and located in Singosari, Malang. PT. Kencana Tiara Gemilang products are geosynthetic, agricultural and innovation products. Problems that often occur in the production process are sales & marketing take a long time to receive some orders, PPIC makes the wrong calculations in determining raw materials, and the production process takes a long time because of Human Resources (HR). For this reason, it is necessary to evaluate the production process. After conducting interviews and observations, it can be seen that the production process is divided into three business processes, such as the production planning process, the production process, and the product evaluation process. The three business processes will be modeled by using the Business Process Model and Nation (BPMN) with a bizagi modeler as a tool. Furthermore, evaluation and analysis were carried out using the Failure Mode and Effect Analysis (FMEA) method to get the priority of the existing problems based on the RPN value. After that, the next step is to make recommendations for business process improvements using the Business Process Improvement (BPI) method with streaming tools. Finally, compare the results of the current business process simulation (AS-IS) and recommendations (TO-BE). The simulation comparison results show that there is a savings in the production planning business process of 21.55 % for Max Time and 5.01 % for Average Time, the production business process is 18.36 % for Max Time and 16.38 % for Average Time, and The product evaluation business process is 32.06 for Max Time and 42.48 % for average time. Savings indicates that the duration of time has decreased from the current ongoing business process (AS-IS) into a business process recommendation (TO-BE).

Abstract

Nowadays, technological developments require various sectors to be able to develop their capabilities. One of the sectors that must follow the development of this technology is MSMEs as an important pillar in the Indonesian economy at a GDP of 61.07%. In its practice, only 9% of MSMEs have digitized, but another 30% have not implemented it and are still using conventional methods (manual) in their sales system. This manual method usually takes a long time and is not effective because it is prone to calculation errors that can hinder decision-making, such as errors in the inventory system and sales reports. Based on this problem, the researcher developed a point of sale application, namely WarunkQu, using the flutter framework to make it easier for MSME actors or shop owners to record and get sales reports. This research was conducted using the waterfall method because the problems obtained were clearly defined. This system uses the flutter framework to get output in the form of a mobile application that can be used on all android devices. The results of testing the WarunkQu application were carried out using functional testing (black box testing) with an average success rate of 100% and usability testing with an average value of 91. This value is included in the very good category and is assumed to be accepted by users.
