Abstract

Computer network laboratory has become a crucial aspect in learning and practicals, although network device limitations remain the main challenge. Learning computer networks using simulators or emulators can save costs, but has limitations unlike using real devices. Learning using remote laboratories has become an alternative solution to the problem. Implementation of remote laboratories with IPv6 protocol using descriptive method approach has been successfully carried out. This implementation provides significant benefits for students in working on practicals remotely.Guided interviews were conducted to evaluate the comfort of using remote labs. The interview results for the evaluation of remote lab usage showed that the majority of respondents (81.3%) felt helped by the presence of network devices that can be remotely accessed with an IPv6 address. Meanwhile, a small portion (10.4%) of respondents preferred to use GNS3 or Packet Tracer. Regarding the problem of connecting to remote routers, the majority of respondents (52.1%) felt that the internet connection at their residence was very smooth for accessing remote devices in the Computer Network Laboratory. Conversely, 39.6% of respondents experienced problems with less smooth connections. 8.3% of respondents felt that their connection was not smooth, sometimes disconnected during configuration, potentially causing configuration failure.

Abstract

The energy sector in the Indonesian capital market is characterized by high volatility, which is sensitive to external factors. This sensitivity leads to complexity in investment decision-making and trader emotional bias. This study employs a Support Vector Machine (SVM)-based trading strategy that incorporates technical indicators, such as Bollinger Bands, the Stochastic Oscillator, On-Balance Volume, and the Average Directional Index, to generate objective transaction signals for 14 energy sector stocks. Historical data from 2015 to 2025 was used, and three kernel types (RBF, polynomial, and sigmoid) were optimized through grid search. The evaluation used classification metrics and backtesting with an initial capital of Rp 100 million. The results showed F1 scores ranging from 35.83% to 47.86%. DEWA achieved the best performance with an accuracy of 66.67% and an F1 score of 47.86%. Backtesting yielded positive returns for 71.4% of stocks, with an average return of 26.85%. RAJA achieved optimal performance, with a 158.97% return and a Sharpe ratio of 1.48, outperforming the buy-and-hold strategy by 37.47%. The main advantage lies in superior risk management, with an average drawdown of -10.64%, compared to the buy-and-hold strategy -48.91%. This results in a 76.1% reduction in risk. The SVM strategy proved effective for low-risk tolerance investors but underperforms during periods of extreme bullish momentum.

Abstract

Research in mathematics and statistics can be categorized into two main types: analytical-theoretical research and applied-practical research, both of which make significant contributions to statistical analysis. This research is particularly relevant to the analysis of large-scale binary variables, where the binomial distribution is often used as the basis for computation. In such cases, the normal distribution can serve as an approximation to the binomial distribution, reducing the complexity of calculations. This study aims to demonstrate that the normal distribution can be used as an approximation for the binomial distribution. Two proof methods are presented: one utilizing the moment-generating function and the other employing Stirling's formula. The methodology involves a literature review by gathering and analyzing various relevant references. The findings indicate that as the value of ? n increases, the difference between calculations using the binomial and normal distributions approaches zero exponentially.

Abstract

Abstract This paper is the result of the leadership training that was conducted by the DWCU Faculty of Information Technology Service Team in the first of the three stages of mentoring that was agreed by the GKJ Wirobrajan assembly. The leadership training was intended for church activists, consisting of assemblies, commissions and regional administrators, with the aim of strengthening motivation as servants at GKJ Wirobrajan after the COVID-19 pandemic. The next goal is to introduce a steward leader model in the church that emphasizes a participatory approach in the ministry of the church, so that it does not rely on the pastor as the figure of the church. The final result from the leadership training is that the servants of the church can reinterpret their understanding of the meaning of service, a participatory approach in ministry and have a commitment to serve that is heard and supported by the other church activists. To achieve this goal, the method used in the leadership training is interactive -reflective, with a training flow done in the form of a combination of models between worship, lectures, group dynamics, and self-reflection. The final result that can be obtained after the training of the first stage of the board has three important things as the basis for the next stage, namely interpreting the meaning of authenticity service, a new awareness of being a participatory servant, and personal reflection that touches the spiritual aspect of a servant. Keywords: GKJ Wirobrajan, Service, Steward Leaders, Interactives-Reflective, Participatory Approach

Abstract

Tarakanita Senior High School (SMA) Magelang is one of the private high schools in Magelang, Central Java, which was established in 1984. The problem faced by Tarakanita Senior High School is the lack of teaching staff who can train students to prepare themselves to take part in the 2024 OSN in mathematics. Community service activities aim to help Tarakanita Senior High School students prepare themselves for the OSN Mathematics. The mentoring was attended by 8 students in grades 10 and 11 who were approved by the school to take part in the OSN Mathematics. The method of implementing the activity includes: technical coordination of activities with the vice principal and mathematics teacher, mentoring in preparation for the OSN Mathematics in the form of completing and discussing practice questions, and evaluation with teachers and students of Tarakanita Senior High School Magelang. The series of activities were carried out in November 2023 - April 2024. Evaluation of the success of the activity was carried out at the end of the mentoring for 5 students who actively participated in the activity until the end and 2 mentoring teachers using Gform. The results showed a value of 4.75 (teachers) and 4.58 (students) on a scale of 1 (very bad) to 5 (very good). These results indicate that the implementation of community service has been very good. These results are also reinforced by verbal input from teachers at the end of the activity who expect similar activities to be carried out again in 2025.
