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 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

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.

Abstract

Server room is a room used to store server computers, network equipment such as routers, server computers and other important equipment. This server room requires special attention to protect the equipment in it, such as temperature, humidity, fire and other disasters. Therefore, in this study it is proposed to implement a server room monitoring system with the modbus interconnection protocol to measure temperature, humidity, vibration and electric current conditions in the server room. The system uses 1 master to display data and provide warnings and 2 slaves paired with sensors. The system is connected via the RS485 module and data transmission uses Modbus RTU. In addition, the system uses a master-slave which uses Wemos D1 mini on the master and Arduino Nano on the slave connected to the DHT11, SW420 and SCT-013-00 sensors. The results of this study are that the system as a whole can monitor the server room via LCD16x2 and Telegram and the system can provide warnings when room conditions are abnormal in the form of alarms with minor, major and critical levels as well as warning notifications to Telegram when in predetermined conditions. The system can send sensor data from slave to master with a cable length of 5 meters for slave 2 and 4 meters for slave 1. At a timeout value of 3574ms the system has an average time interval for sending data from slave 1 which is 196.4ms and from slave 2 which is 598.5ms with data read by the master having a length of 13-14 data.

Abstract

Moodle provides convenience in the teaching and learning process in this modern era. Starting from learning material, working on tests, uploading files can be done easily. Apart from the convenience provided and the increasing number of teaching and learning processes using Moodle, the burden on the Moodle server will also be greater. Apache jMeter provides tools for monitoring and testing performance. With a simple GUI, its use is not difficult to learn. In this research, we tested the moodle server with the PostgreSQL database installed in virtualbox. Then a performance test was carried out through Apache jMeter which included a CPU performance test, Disk I/O performance test, and a memory performance test on the login page and quiz submit page. The simulation was carried out in stages starting from one repetition, ten repetitions, fifty repetitions, and one hundred repetitions. From the test results it was found that the test results showed the same results because they were carried out in the same session at the same time

Abstract

Information technology is currently developing very rapidly so that several e-commerce and social media companies have created a new live video-based platform called live shopping. Currently live shopping is used as a means of buying and selling online and of course through this platform it is hoped that it will be able to increase public buying interest. However, to be able to increase buying interest, streamers or broadcasters need to pay attention to the factors that influence consumers' purchase intentions for a product, namely trust in the product. Trust in the product or trust in the product is also driven by brand recognition or brand awareness and perceived value. This study aims to find out how brand awareness and perceived value affect trust in products and to find out the effect of trust in products on purchase intentions or consumer purchase intentions. This study used the Structural Equation Model - Covariance Based (SEM-CB) method and obtained clean data for 433 respondents. From the research conducted, it was found that the hypothesis was not accepted, namely brand awareness had an effect on trust in products with a p(probability) value of 0.394 and there was an accepted hypothesis, namely perceived value had an effect on trust in products with a p(probability) value <0.001 and the trust hypothesis product has an effect on purchase intention with a value of p(probability) < 0.001.

Abstract

As time progresses, technology also experiences rapid advancement. However, this advancement is not accompanied by an improvement in the interaction between computers and humans. This is certainly a significant impact on users of technology, particularly those with mobility disabilities. Smart wheelchair technology has already been widely used to assist people with disabilities, but the problem of interaction with computers still reduces user comfort. Some new types of interaction have been offered in previous research, including using voice, but this method is considered less effective due to the need for a minimally noisy environment. Another offered method of interaction is using eye gaze estimation using conventional algorithms or machine learning. For this, conventional algorithms are considered less effective due to their low adaptability with different users. CNN-based algorithms are chosen in this research because of their ability to extract features from images, allowing the algorithm to adapt to new data. The accuracy of the model in this research was 96% with a loss of 0.02 during the training phase. The system can run the algorithm in 0.16 seconds using CUDA acceleration. The system only uses 12 watts of electricity, making it possible to run the system using a battery. From the testing that was carried out and the results obtained, it can be concluded that the system runs well to estimate the direction of the user.

Abstract

Waste is an object that comes from the remaining waste of a product that is no longer used. The increase in waste generation in Indonesia has reached 28 million tons/year. This happens because to lack of awareness many people about the issue of environmental pollution. In addition, there has been an increasing activity of hanging out in cafes that do not implement the concept of eco-friendly. Therefore, the cafe should implement a sustainable business process in the sustainability of a business in order to survive and compete in the long term. The purpose of this research is to fix the problems and improve the quality of business processes with BPMN (Business Process Management Notation) modeling. This research aim to fix problems in business processes. In this research are used lean management because. This method focuses on the value of product and can minimize waste. At the define stage using SIPOC (Supplier, Input, Process, Output, Customer) diagram and waste identification. At the measure stage is identification CTQ (Critical To Quality) and measuring process capability using values of DPMO (Defect Per Million Opportunities). At the analysis stage, this research used Root Cause Analysis (RCA) and BPMN modeling with Bizagi Modeler. From the results of the analysis, it was found that there were four processes that were problematic and identified as wasteful. There is types of waste that occurs in business process is waste inventory, overprocessing, defects and motion. Then improvements business process can minimize waste by changing and adding business process activities.
