Abstract

In the world of IoT, it is involving many devices, each Node needs to send/receive the data from/to Datacenter. The Lora Gateway is usually used to achieve that communication. There are many ways to implement the Lora Gateway, it may use available Lora Gateway in the market. This method may be faster but need to have an extra fee, especially when many gateways are needed. Another method is by using the available GSM Network Gateway, this may lead fast but require managing Simcard at each Node. Both are less flexible as the data format needs to follow according to the standard of the Gateway which is chosen. Some methods select to build the Lora Gateway by themself, but this requires some development and integration that leads to giving extra time. To compensate above problem this project is involved. The aim is to prove, that it is possible to build a Low-Cost Lora Gateway based Time Division with the help of on .Net Core prgramming. As of today .Net Core can run in the Linux OS environment smoothly, hence building Lora Gateway based Time Division using on .Net Core is very possible to be done. By developing for all devices using .Net Core the communication data across the device is easy to achieve. It is because all projects in each device reference the same library that contains the same data entities and services. This project proves that building a Low-Cost Lora Gateway based on .Net Core is successfully done. The development and integration are relatively easy and fast. The fee to build the Lora Gateway is less compared to using available Gateway in the market or using GSM Gateway.

Abstract

In the implementation of augmented reality, the natural process of human-computer interaction continues to be a challenge, specifically to reduce the complexity in the effort of using and providing comfortability. Therefore, it is necessary to search for methods and tools to simplify the complex process of building Augmented Reality applications. Vuforia is a multi-platform that has long been used as an Augmented Reality application development framework. Android and iOS platform frameworks are the new alternatives following the development of cellular technology. Furthermore, a comparative capability was conducted between Vuforia and ARCore on the Android platform. The general performance and the ability to understand the environment include working in horizontal and vertical planes, the ability to work based on lighting conditions, and the distance of the camera during the tests. The results showed that ARCore is superior to Vuforia in almost all testing metrics. However, in overexposed or too dim lighting and at very close surfaces, Vuforia is slightly superior but not essential. Therefore, it can be concluded that ARCore's capability is better than Vuforia.

Abstract

This study uses the Systematic Literature Review (SLR) method to examine the application of deep learning techniques focusing on BISINDO (Bahasa Isyarat Indonesia) image recognition. This is crucial for enhancing communication accessibility for the hearing-impaired community. The SLR process involves three stages: planning, conducting, and reporting. During the planning stage, research topics, questions, and search criteria are established, while the conducting stage involves comprehensive article retrieval and rigorous filtering. In the reporting stage, the study highlights the significance of various deep learning methodologies, including the implementation of several algorithms that ace in image recognition. For example, Convolutional Neural Network (CNN), Long Short Term Memory (LSTM), and a combination of the two methods, each with unique advantages and limitations. Along with that, this paper aims to find gaps in previous research and act as a guide for future deep learning model development. Moreover, the research outlines the development of a high-performance model, emphasizing key phases such as image augmentation and data preprocessing, as well as model optimization. These efforts contribute to a better understanding of BISINDO image recognition, offering valuable insights for researchers and practitioners aiming to support easier accessibility and communication for the hearing-impaired community through advanced deep learning approaches.

Abstract

Technological advances in this era can support public services to serve the public more quickly and responsively. One of the electronic public services used by citizens in Indonesia is the application for a passport. After launching to the public in early 2022, the mobile app M-Paspor is still experiencing some obstacles. This study aims to get recommendations for government consideration based on public experience as users of the M-Paspor application. This study integrates the e-Govqual model initiated by Papadomichelaki & Mentzas and End User Computing Satisfaction by Doll & Tork Zadeh. Six dimensions are used: ease of use, trust, functionality of the interaction environment, reliability, content and appearance of information, and citizen support. With the questionnaire distributed through social media, we analyzed data from 111 respondents. We conducted an analysis using SmartPLS to validate the survey. The result implied that Citizen Support, Functionality of the Interaction Environment, and Reliability significantly influence End User Computing Satisfaction of M-Paspor users

Abstract

This study originated from the lack of enthusiasm of students following the learning of milling machining in the classroom, because of the many distractions that make it difficult for students to concentrate. The purpose of this study is to determine whether there is a difference in students' learning concentration in the subject of milling machining techniques of vocational high school students when they are taught with whiteboard animation media and textbooks. This research design is a quasi-experiment with post-test only. Based on the researcher's consideration and initial interviews, the subjects of this study were formulated as two classes. The number of students for the experimental class XI TPM 1 (15 people) and the conventional class XI TPM 2 (15 people). The experimental class XI TPM 1 was given whiteboard animation learning media, while the conventional class XI TPM 2 was given conventional learning. To analyze the research data, t-test technique was used. The results of the t-test analysis showed that, compared to the conventional learning method, students learned milling machining techniques with higher concentration.
