Abstract

Network security is a crucial aspect of information systems, especially in the internal networks of institutions or organizations. This study aims to develop a Squid-based firewall system as an effective network security solution to control and filter internet access. The method used involves open-source system development by utilizing Debian Linux and Squid Proxy software. Installation and configuration processes were conducted to manage access restrictions based on HTTP/HTTPS protocols, IP addresses, and usage time. The implementation results show that the developed firewall system is capable of blocking unwanted websites, regulating access times, and recording user activities through system logs. This system also offers ease for administrators in monitoring and managing network traffic efficiently. With this approach, institutions or organizations are expected to enhance their internal network security without incurring high licensing costs. This research contributes to the utilization of open-source technology for independently and affordably addressing network security needs.

Abstract

Social ethics are an essential aspect of students’ social development as they influence the quality of social interactions and the learning environment in schools. Low social ethics among students are still frequently found, such as impolite language, lack of honesty, low tolerance, and limited empathy toward peers. This study aimed to examine the effectiveness of group guidance services using the sociodrama method in improving students’ social ethics. This research employed a quantitative approach with a pre-experimental design using a one group pretest-posttest model. The research subjects consisted of 10 students from class VII.1 of SMP Negeri 1 Lembang Jaya, Solok Regency, selected through purposive sampling. Data were collected using a social ethics questionnaire that had been tested for validity and reliability. Data analysis techniques included percentage interval classification and t-test analysis. The results indicated that before the implementation of group guidance using the sociodrama method, students’ social ethics were categorized as low to moderate. After the intervention, students’ social ethics improved significantly and were categorized as high to very high. The t-test results revealed a significant difference between pretest and posttest scores with a significance value of p < 0.05. These findings indicate that group guidance services using the sociodrama method are effective in enhancing students’ social ethics. Therefore, it is recommended that school counselors apply the sociodrama method as an alternative strategy in group guidance services to foster positive social behavior and improve students’ interpersonal ethics within the school environment.
