Abstract

Since COVID-19, online learning has taken on an increasingly prominent role. Moodle is a popular online learning platform. Its implementation necessitates various support components, including a web server and an e-learning database server. The purpose of this study is to examine the optimization of web servers and database servers when there are multiple large connections at SMK N 2 Depok's E-learning. A pre-experimental one-group pretest-posttest design was used to conduct experimental research before and after optimization. Response time and throughput performance variables are used to assess performance on the Web Server, whereas response time and transaction per second performance are measured on the Database Server. The tools utilized in this study were Apache Benchmark and Sysbench. The population in this study was 2180 active users, with a total sample of 338 connections to access e-learning. The results of this research indicate that the performance of the Moodle e-learning web server can be optimized by tuning the web server configuration. There was a significant increase in performance on the web server after optimization. The performance of the moodle e-learning database server performance can be optimized by optimizing the database server configuration tuning.  There is a significant increase in the performance of the database server after optimization. To use e-learning efficiently when using several connections at the same time, the web server and database server must be optimized through server tuning. This can boost the effectiveness of e-learning in the classroom. As a result, e-learning developers should consider optimizing e-learning server settings.

Abstract

This study explores the application of machine learning for local market prediction in e-commerce. By leveraging the RFM segmentation method, the model predicts product sales based on user shopping patterns. The RFM score, calculated using recency, frequency, and monetary values of customer purchases, segments customers into distinct categories. The research utilizes a dataset obtained through seven parameters and performs data preprocessing. K-Means clustering then classifies customers into Low, Medium, and High levels based on their RFM scores. Customers in the Low category exhibit low purchase activity but high product browsing. The Medium segment displays consistent purchases of a limited product range. High-level customers demonstrate frequent purchases with significant spending. The identified customer segments enable targeted marketing strategies. For Low-level customers, discounts or product feature promotions can incentivize purchases. Combining product offerings can entice Medium-level customers to explore new products. Finally, High-level customers can be engaged through loyalty programs offering rewards. This approach empowers e-commerce sellers to tailor marketing strategies for each customer segment, enhancing market dominance.

Abstract

Tourism villages play an important role in the development and sustainability of a region by encouraging economic growth, cultural preservation, environmental preservation, and community development. Widosari Tourism Village is one of the tourist villages that attracts many visitors, as can be seen from the significant increase in traffic visiting the promotional website after being declared as a nominee in the Top 50 Indonesian Tourism Village Award 2022 event. However, the increase in traffic visiting the website was not matched by the website's carrying capacity. in providing services and conveying information to tourists. This has an impact on the lack of tour package sales in the Widosari Tourism Village. However, after redesigning the interface, drastic changes occurred, especially in the increase in sales of tour packages. This research was conducted to reveal and tell about the extent of the impact or benefits of a website redesign that is adapted to design principles as it is today compared to before the redesign was carried out. The method used in this research is descriptive qualitative research. In this research, the conclusion was obtained that after the website redesign was carried out, in terms of tourist reservation services, managers and tourists found it easier to communicate and connect, then the information on the website was easier for tourists to understand and capture. So, the presence of the Widosari Tourism Village promotional website functions as a means to facilitate tourism activities in the Widosari Tourism Village.

Abstract

This study aims to determine (1) the implementation of occupational health and safety (OHS) using the Zerosicks method in vocational education and (2) the significant relationship between each aspect of the countenance stake evaluation model. The model consists of 3 stages: input (Antecedent), process (Transaction), and output. Then, the population in this study involved 727 students with a sample size of 258.03, and this research was conducted in April-June 2021 at the Prambanan Muhammadiyah Vocational High School. Furthermore, the data analysis techniques used were quantitative descriptive and SEM (Structural Equation Modeling). The study findings reveal that (1) the antecedent stage, encompassing environment, hazard, risk, knowledge, and standardization indicators, is evaluated as excellent by teachers and predominantly good by students. In the Transaction stage, focusing on risk management control, solution, implementation, and culture indicators, teachers rate it as good to perfect, while students generally rate it as very good to good. Moreover, the output stage, comprising control and OHS behavior awareness indicators, is deemed outstanding by both teachers and students. (2) The indicators of the model are valid and achievable following the results of the confirmatory factor analysis, and the structure of the theoretical model fulfils the Goodness of Fit criteria for empirical data because it has six criteria. Furthermore, an antecedent has a significant effect on Transaction and OHS Output, while a Transaction has a significant effect on OHS Output.

Abstract

The large number of graduates who lack the skills needed for the workplace makes it difficult for them to find employment. This study aims to analyze the influence of teachers, technology, and social capital in preparing vocational school graduates for their first jobs. Participants came from five districts in Yogyakarta, including state and private VHS with engineering expertise, including 25 teachers and 99 students. The research steps involve conducting literature reviews, focus group discussions, and data collection via questionnaires. The results show that: (1) the stability of choosing a career that is in line with their education for graduates who study further is better than graduates who work or are entrepreneurs; (2) the measurement model showed valid and reliable results: outer loading (0.702 -0.967), AVE ³ 0.5, Cronbach's alpha ³ 0.7, Fornell-Larcker criterion, and HTMT ratio. The structural model using the SRMR is 0.078 (good fit); (3) With p-value 0.000 (sig < 0.05), there is direct significant influence between TCR -> TGR (f2 0.897), TCR -> SCR (f2 0.638) with large effect, and TCR -> STWT (f2 0.310), TGR -> STWT (f2 0.189), SCR -> STWT (f2 0.267) with medium effect and the indirect influence (TCR -> STWT), which is mediated by TGR and SCR. The role of the teacher (TCR) has a significant impact on optimizing the role of technology (TGR) and social capital (SCR) in the STWT effectivity. The role of teachers, technology, and social capital all have significant and medium effects on the STWT smoothness. This is in line with the concept of Industry 5.0, specifically integration. Education in the Industry 5.0 era is dependent not just on the contributors' roles but also on integration.

Abstract

The Central Java Provincial Government has implemented the "Open Data Jateng" system since 2019 for public services. Open Data is part of the application of big data, and the system does not yet have evidence to meet data needs. So, an explanatory method of research was conducted using a prediction study. The research variables are based on the development of the Technology Acceptance Model (TAM) theory and the 3Q model theory. 130 respondents from the ex-Karesidenan of Semarang City filled out 21 statements, then tested through Partial Least Square - Structural Equation Modeling (PLS-SEM). The result is that there is the highest relationship in the TAM variable, namely: the influence of the perceived usefulness variable on the behavioral intention to use variable is 42.5%, with the predictive power of increasing the two variables to 75.2% if there is treatment/policy. The relationship between TAM variables and the 3Q model was found, such as the effect between the information quality variable and perceived usefulness was 13.3%, which has a low level of influence. Although low, the predictive power is also high at 65.4% if there is a treatment or policy that supports the information quality variable. The study concluded that the optimization of Open Data Jateng can be through policy support in order to improve the quality of information.

Abstract

Motor vehicle theft is a crime that can potentially harm the owner of the vehicle. This crime should be anticipated, and a security system should be implemented to avoid vehicle theft. Research about vehicle security systems has run into an uptrend. Previous research has already developed security system devices for vehicles with many peripherals. This study aims to develop a new low-cost vehicle security device with location change calculation to cut unused peripherals. The proposed device has a logic checker, horn controller, and vehicle controller as security systems. According to the testing result, the device can detect the vehicle status from off to on while the security system is active. The device will turn on the horn and turn the vehicle off. This function always works at 100%. This device also detects theft according to the location change. This feature works at a 100% rate, with an average error reading location of 4,83m and an average error distance calculation of 0,91m. This distance is tolerable because the owner can still see the vehicle. This research result proves that the device can be used to secure the vehicle. This device's performance will increase if placed outside the building. The data was also successfully sent to the IoT platform without data loss or incomplete data. Compared with other research, the proposed device has fewer peripherals with the same or more security features.

Abstract

The purpose of the study is to compile concepts related to computational thinking skills in the context of computer programming subject. The research design used is data theorization (grounded theory) with open coding and axial coding data analysis techniques. Three types of data collection protocols are used: interview protocols, observation protocols, and recording protocols. The characteristics informants used are students who have experience learning computer programming in the vocational high school. The research produced several concepts, namely the problem concept, which then gave rise to the computational thinking skills concept. The problem concept consists of three sub-concepts: the common problem sub-concept, the medium problem sub-concept, and the high problem sub-concept. The concept of computational thinking skills is a set of skills required in the problem-solving process in computer programming. Computational thinking is not just a thought process but an expression of skills that others can observe. In the computer programming subject context, two concepts influence the process of mastering computational thinking skills: the guidance strategies concept and the information sources concept. The concept of success becomes a mediator in developing computational thinking skills. The theory produced in this study can be used as a basis for conducting research with quantitative designs related to deductive proof of the theory.
