Abstract

Digital identity is something that is really needed in carrying out activities on the internet, especially in social networking. Everyone who has a social network on the internet is required to provide a digital identity such as name, date of birth, telephone number and personal photo. In the current era, digital identities are often reported to be leaked, stolen, and misused by irresponsible parties. This is a problem that causes privacy concerns for social network users to share their digital identity which is personal data. In addition, privacy concerns also affect social network users in protecting their digital identity privacy. The aim of this study is to find out how social network users protect their digital identity using the Protection Motivation Theory (PMT) theory by identifying two PMT factors, namely Self-Efficacy and Perceived Severity factors to examine privacy concerns that arise on social networks. This study also aims to find out whether gender factors have differences in willingness to share digital identities on social networks. This study used the SEM-CB method by distributing questionnaires to 309 respondents. The results found that there is a positive influence on privacy concerns in the willingness to share digital identities. Another finding found that Self-Efficacy and Perceived Severity had a positive effect on privacy concerns, but not the gender factor with negative results indicating that there was no difference between genders in the willingness to share digital identity on social networks.

Abstract

Network Traffic Analysis is a process of gaining knowledge and conclusions related to information from observable data flow characteristics. These characteristics include the identity, location of the source and destination of the stream, the existence of the stream, the number, frequency, and duration of that stream of information. Continuous network monitoring and analysis helps in keeping the network at its performance with little downtime. One method that can be used to analyze network traffic is to utilize the Arkime platform. In this final project, Arkime will be applied to monitor network traffic by collecting traffic data and providing visualization of the data which will then be analyzed from the traffic data. The main components that make up this system are a managed switch and capture-node in which the Arkime platform configuration and elastic stack components are Elasticsearch, and Metricbeat. Arkime itself consists of two elements, arkime-capture as a package catcher and arkime-viewer for data analysis and visualization. In the data retrieval process, the data used is direct data from network traffic in the researcher's environment that is captured using the arkime-capture component. The built system will also be tested for resource usage performance at the time of data collection and using specific network loads.

Abstract

MSME companies in Malang City often employ their employees on part-time contracts, mainly due to difficulties in obtaining capital and the increasing number of students who are ready to work part-time. For students, working part time is a way to gain work experience as well as extra pocket money. So far, the MSME companies employee recruitment process still relies on forums on social media such as Facebook and often experiences difficulties due to the limitations of the job vacancy forums, such as poor relevance, no templates for job postings, and rare information updates. To overcome this problem, researchers developed a part-time job search and offer application called Jobhere which was developed with progressive web app technology. The Jobhere app was developed using the SDLC waterfall model. The use of the waterfall model is because the functional requirements of the system have been defined at the beginning of development and there is no need for iterations and changes in requirements.

Abstract

Losing goods such as being negligent in guarding goods can result in the emergence of a criminal act, namely embezzlement of goods. Embezzlement of goods is a case that the goods from the owner are already in the hands of the perpetrator without the perpetrator committing a crime. Based on criminal statistics for 2021, there were 37,097 crimes related to fraud, embezzlement, and corruption in 2020. The researcher also got direct information from UB Security who said that cases of lost goods are not uncommon in UB's campus environment. In addition, information dissemination of missing items has not been implemented in UB. Therefore, we need a solution in the form of a system that can provide information about the incident of lost goods. The development of the PWA Lost and Found UB website uses the Prototyping development method using several tests, namely validation testing using Black-box Testing, usability testing (effectiveness) using Scenario Testing, and usability testing (satisfaction) using the System Usability Scale (SUS). The test results show that the functional requirements run well and users can perform all testing scenarios properly and have an effectiveness level of 100% for each user. The SUS score obtained was 83 which illustrates several points in SUS, namely the Grade Scale with a value of B, an Adjective Rating with an Excellent value, and the Acceptability Range with an Acceptable value.

Abstract

The pandemic has had a major impact on human mental health, which has had an impact on the instability of emotions. Unstable emotions can cause stress, characterized by feelings of sadness, gloom, and unhappiness. Prolonged feelings of sadness can be a sign of depression. Therefore, tools are needed that able to provide information about the intensity of sadness felt in order to reduce prolonged sadness. Some studies have successfully created tools to detect emotions with voice signal. Therefore, the purpose of this research is to make a system that is able to detect the intensity of sad emotions through human's voice. The research was conducted using BFCC feature extraction, which has a better accuracy than the MFCC method if the sample data has a lot of noise. The system will work with the help of a microphone as a device to record. In the first process, the system will record using a microphone, the recorded results will be processed to extract the features and classify them. After the prediction results are obtained, the results will be displayed on the LCD display. This research uses the Crowd Sourced Emotional Actors Dataset (CREMA-D) consisting of several emotions with high, low, and mid levels, but in this research only focuses on the use of sad emotions. The results of the study obtained an accuracy of 60% with an average signal-to-ratio (SNR) of 23.9 dB, and has an average difference of 11.76 dB better than the MFCC method.

Abstract

Hypoxia is a condition when the tissues in the body lack oxygen so that their functionality is disrupted and can be fatal, such as organ damage and even death. One of the causes of hypoxia is environmental factors such as being at high altitudes with minimal oxygen. Therefore, hypoxia is also a frightening specter for mountain climbers, where there are minimal medical facilities to check the condition of climbers. Therefore, in this study designed a portable system to detect hypoxia in climbers. Hypoxia detection was carried out using heart rate (BPM) and blood oxygen saturation (SpO2) parameters whose data were acquired using the MAX30102 sensor. After that, the data was processed and classified using the naive Bayes method on the Arduino Mega 2560 microcontroller. This system uses a battery for its power source so that it is more portable and can still be used in mountain areas where there is no power source. Due to very limited battery power, a low-power mode is implemented in the form of sleep mode so that it can save battery power consumption. In testing the BPM and SpO2 readings with the MAX30102 sensor, an accuracy of 98.03% and 97.62% was obtained. In the naive Bayes classification test results obtained an accuracy of 93.33% with a computation time of 829.2 µs. As well as for power efficiency with low power mode, a decrease in current consumption reaches 70.13%.

Abstract

The development of information technology is currently changing the way people shop, giving rise to new behaviors in online shopping. This has prompted businesses to adopt various selling methods, one of which is live shopping on social media or e-commerce platforms. Live shopping involves using video to introduce and promote products, with the aim of influencing consumers' trust in the product. Trust in a product can be influenced by factors such as product quality, perceived value, and the frequency of participation in live shopping activities. This study aims to determine the influence of these factors on trust in a product during live shopping, using a quantitative approach and Structural Equation Modeling-Covariance Based (SEM-CB) method. The researchers distributed online surveys and collected clean data from 433 respondents. Data processing was performed using IBM SPSS 22 and IBM AMOS 26 tools. The results of the study showed that one hypothesis was not accepted: that product quality has an influence on trust in the product, with a probability (p) value of 0.805. In this case, the audience may not necessarily trust the product quality when live shopping activities on social media and e-commerce.

Abstract

Indonesia is a country dominated by a Muslim population, especially in Java, especially East Java Province. In 2014, there were 36,472,783 people who follow Islam based on a survey conducted by the Ministry of Religious Affairs and BPS East Java. While in 2019 the same survey was conducted again and found as many as 37,558,874 people who follow Islam. This figure also contributes to the number of people who perform Umrah to the holy land. Therefore, Farfasa Tour Agency as one of the religious tourism service providers has several problems in management. There are frequent problems of agency customers not being able to get information about the schedule, too often going back and forth to the agency office to make sure the data is correct, and recording loans that are often missed. Therefore, an information system application is needed that is expected to help Farfasa Umroh Agency to solve the problem. The information system is developed using the waterfall method which will be developed on an Android-based platform and website. Information system development will go through the stages of needs analysis, design, implementation, and testing. Application development on Android will be native using the Kotlin programming language. The development of web-based applications will use the JavaScript programming language that uses ReactJs to build the user interface.

Abstract

Micro, Small and Medium Enterprises (UMKM) play a very important role in terms of Indonesia's economic development. However, along with the rapid advancement of technology nowadays, there are still many UMKM players who have not yet utilized these technological advances. To develop the ability to record sales transactions, CV Cokelat Turqy (Ziyadatur Rizqy) has an urgency to need a good sales invoice generation application user interface design. Therefore, in this thesis project, a sales invoicing application user interface design is built that can help fulfill this urgency. The user interface prototype was designed using the Prototyping Model also using the System Usability Scale (SUS) as a parameter to measure the level of user satisfaction and the online test tool to measure the responsiveness of the prototype. Before testing, the task scenario is determined first as a guide for respondents in conducting the test. The results of testing the satisfaction level factor show that the resulting prototype has fallen into the category of good products. The results of testing the responsiveness level factor of the prototype on three different tablet device screen resolutions show that the resulting prototype is included in the responsive prototype.
