Abstract

This study investigated the effectiveness of Scenario-Based Learning (SBL) using Wireshark in improving students’ packet analysis and network disturbance diagnostic skills. The study addressed the gap between theoretical networking instruction and students’ limited ability to interpret real network traffic and troubleshoot practical cases. The key argument is that integrating authentic troubleshooting scenarios with professional packet analysis tools enhances higher-order analytical competence. A quantitative pre-experimental one-group pretest–posttest design was employed. Thirty-two second-year networking students participated in a four-week intervention consisting of structured scenario modules using Wireshark (version 4.x) in a controlled laboratory environment. Data were collected through a 20-item performance-based test measuring conceptual understanding, packet interpretation, and network diagnosis. Statistical analysis included descriptive statistics, Shapiro–Wilk normality testing, paired-sample t-test, and Cohen’s d effect size calculation. The mean score increased from 56.41 (SD = 8.72) in the pretest to 78.63 (SD = 7.95) in the posttest. The paired-sample t-test revealed a significant difference, t(31) = 15.87, p < 0.001. The calculated effect size (Cohen’s d = 2.80) indicated a very large effect. The highest gains were observed in packet interpretation and network diagnosis components. These results confirm that SBL using Wireshark significantly improves analytical and troubleshooting competence. The absence of a control group, limited sample size (N = 32), short intervention duration, and single-institution context may restrict generalizability. Future studies employing randomized or longitudinal designs are recommended. This study provides empirical evidence of integrating scenario-based pedagogy with industry-standard packet analysis tools in networking education. It offers a replicable instructional framework that bridges theory and authentic technical practice.

Abstract

Komunikasi efektif memiliki peran penting dalam mendukung koordinasi kerja, penyampaian informasi, kerja sama tim, serta efektivitas organisasi di lingkungan kerja. Komunikasi yang kurang efektif dapat menyebabkan miskomunikasi, hambatan koordinasi, keterlambatan pekerjaan, serta menurunnya produktivitas karyawan. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman dan keterampilan komunikasi kerja karyawan melalui pelatihan komunikasi efektif di PT Golqi Sukses Mulia. Pelatihan dilaksanakan menggunakan pendekatan experiential learning yang melibatkan pengalaman langsung, diskusi, simulasi, dan games kelompok untuk meningkatkan partisipasi aktif peserta selama proses pembelajaran. Peserta kegiatan berjumlah 40 karyawan office dari beberapa divisi di PT Golqi Sukses Mulia. Teknik pengumpulan data dilakukan melalui kuesioner, wawancara, pre-test, post-test, dan evaluasi pelatihan. Materi pelatihan meliputi self-awareness, active listening, pemberian umpan balik konstruktif, structured communication, serta closed-loop communication. Selain itu, peserta mengikuti simulasi kelompok berupa games “Bridge Challenge” yang dirancang untuk meningkatkan kemampuan komunikasi, kerja sama tim, koordinasi, pemecahan masalah, dan pengambilan keputusan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta mengenai komunikasi efektif dari 79,7% pada pre-test menjadi 82,9% pada post-test. Peserta juga menunjukkan keterlibatan aktif selama proses diskusi dan simulasi berlangsung. Hasil tersebut menunjukkan bahwa pelatihan komunikasi efektif dengan pendekatan experiential learning mampu meningkatkan pemahaman dan keterampilan komunikasi kerja karyawan. Pelatihan ini diharapkan dapat mendukung terciptanya lingkungan kerja yang lebih kolaboratif, terstruktur, adaptif, dan produktif dalam organisasi.
