Abstract

The issue of divorce remains a complex and sensitive topic within Indonesian society, influenced by various factors such as repeated disputes, domestic violence, lack of harmony, financial difficulties, and other socio-cultural aspects. With the rise of social media, particularly Twitter, public discussions regarding divorce have become more widespread, allowing individuals to express their opinions and sentiments on the subject. These diverse perspectives create a wealth of sentiment data that can be analyzed to understand public perception and societal trends related to divorce. This study aims to classify public sentiment on divorce-related discussions using the Random Forest algorithm, providing insight into how people perceive and react to divorce issues. The research adopts a quantitative approach with a case study framework. The methodology involves data collection through web scraping techniques to gather approximately 1500 tweets containing discussions on divorce. The collected data is then preprocessed, including text cleaning, tokenization, and feature extraction, before being used to train and evaluate the Random Forest model. Sentiments are classified into three categories: negative, neutral, and positive. The classification model's performance is assessed using accuracy and F1-score metrics derived from the confusion matrix to determine its effectiveness in categorizing sentiments. Experimental results indicate that the Random Forest algorithm achieves an accuracy of 70%. The relatively low accuracy is attributed to the imbalance in sentiment class distribution, where negative sentiments dominate while positive sentiments are underrepresented. This imbalance affects the model's ability to predict positive sentiments effectively. The implications of this research contribute to a better understanding of public sentiment dynamics regarding divorce, which can be beneficial for policymakers, psychologists, and social researchers in analyzing societal attitudes towards marital dissolution.

Abstract

Current technological developments have penetrated various sectors of human daily activities, almost every human activity is supported by technology that functions to facilitate the completion of work, starting from things that seem trivial to quite complicated work. Therefore, Banjar Tri Parartha residents who have a business unit in the form of a savings and loan cooperative with funds from member contributions, run it by carrying out cooperative principles to help the economic movement of its citizens based on the principle of family. At this time the process of recording, calculating to the reporting process is still done conventionally, so that cooperative administrators are quite busy every time they make an accountability report that is carried out every year. By running the analysis and design process in the application creation stage using the waterfall method. So in the interface design it is adjusted to what is needed by the cooperative. It is hoped that this research can be a reference in making applications as the next stage. By using the application design starting from the recording stage, processing calculations and presenting reports, it is hoped that all stakeholders will find it easier to monitor and obtain cooperative financial information, so that the transparency of cooperative funds can provide certainty for its members.

Abstract

Financial information is a critical type of data for analysis. However, because much of it is unstructured and widely dispersed, an appropriate analytical method is required, one of which is sentiment analysis. In the financial context, sentiment analysis is employed by the industry to assess public perceptions of companies or market conditions. This study implements a fine-tuned FinBERT model to perform sentiment analysis in the financial sector. The dataset used is a combination of FiQA (Financial Question Answering) and The Financial PhraseBank, consisting of English sentences labeled with negative, neutral, and positive sentiments. The research process involved data preprocessing, tokenization, data splitting, model training, and evaluation using accuracy, precision, recall, F1-score, and confusion matrix metrics. The results show that the model achieved 82% accuracy, with its best performance in the positive class (F1-score 0.88) and the neutral class (F1-score 0.85), but weaker performance in detecting the negative class (F1-score 0.49). These findings indicate that the fine-tuned FinBERT is effective for financial sentiment analysis, particularly for positive and neutral sentiments, though improvements are needed in negative sentiment detection, potentially through expanding training data diversity or applying data augmentation techniques

Abstract

STMIK Bumigora is the first computer college in the province of West Nusa Tenggara (NTB). There are 11 hotspots spread across the campus to provide Internet services through a wireless connection for the academic community. The increasing number of hotspots that must be managed with locations scattered in various Mikrotik routers hence make the process of management and monitoring hotspots become complex, ineffective and efficient. Centralized campus hotspot management using a transparent bridge EoIP over SSTP can help solve the problems at hand. Ethernet over IP (EoIP) Tunneling is a Mikrotik RouterOS protocol that creates an Ethernet tunnel between routers over IP connections. EoIP tunnel built on SSTP tunnel (EoIP over SSTP) with Site-to-Site type. SSTP is a new form of Virtual Private Network (VPN) tunnel that provides a mechanism for encapsulating Point-toPoint Protocol (PPP) traffic through the SSL path of the HTTPS protocol. The IP address of the SSTP interface is used as the local reference and remote address of the EoIP over SSTP tunnel. The application of bridging on EoIP interfaces and interfaces connected to Access Point devices forms a logical network so that the management and monitoring of hotspot services can be performed centrally on one router.

Abstract

STMIK Bumigora Mataram strives to develop a curriculum that adopts the needs of the industrial world. In the past 2 years, Network Management lecturers have experienced problems related to practicum implementation. During this time the learning process uses virtualization installed on each laboratory computer. However, the system has various weaknesses, especially related to the freedom of access and availability. The implementation of Private Cloud Computing based on Proxmox Virtual Environment (PVE) which in the cluster can be a solution to the problems faced. PVE cluster which is made using four servers and integrated with one storage server can be used as a learning media for network management practicum and support high availability so that live migration can be done. Users can manage Virtual Private Servers using Linux Container (LXC) independently with a login and limited access permission account and the configuration can be done through the console and SSH. All practicum materials were successfully tested on LXC. An FTP-based local repository built on a storage server can minimize the bandwidth usage of an Internet connection and speed up the package installation. In addition port forwarding on the gateway router can facilitate the remote access needs on LXC from the Internet.

Abstract

Virtualization technology has been applied to universities with computer study programs to support practicum in Network Management courses. Each user gets a Virtual Private Server (VPS) with container technology. VPS system that is prepared manually requires a long time, especially when the number of users is increasing. The activity repeats every semester so it becomes ineffective and inefficient. Application of automation using Ansible can help to manage VPS objects in the Promox Virtual Environment (PVE) Cluster dynamically. Network Development Life Cycle (NDLC) was used as a method in this study. The design of the VPS management automation system created supports the grouping of container, user and permission resource management for users. The design is implemented in Ansible Playbook. The test results show the average time of making VPS objects per student with an automation system 2 (two) times faster, that is 26.25 seconds compared to the old system which takes 2 minutes 15 seconds. Besides that, the Playbook that was created succeeded in automating the start and stop containers per group of students based on the practicum schedule dynamically so as to maintain the availability of services from the PVE Cluster.

Abstract

The opening of the service port on the Mikrotik router provides an opening for hackers to enter the Mikrotik service to access the router illegally. This research aimed to close certain ports that are gaps for hackers and uses port knocking and telegram bots. The Telegram bot was used as a message notification to managers in real-time to provide information that occurs when the vulnerability scanning process is carried out to find and map weaknesses in the network system. Searching for weaknesses also includes looking for open router service ports such as ports 22, 23, 80, and 8291. This research used the Network Development Life Cycle method, which started from analysis design and prototype simulation to implementation. The research results after testing were able to secure local network service ports against vulnerability scanners on routers using the port knocking method, and testing attack schemes carried out from each scheme could run well on the router’s local network and obtain notifications via telegram bots in real time to administrators. This research contributes to administrators’ ability to secure networks so irresponsible people do not easily infiltrate them.
