Recently, in the distance learning system, video conferencing becomes one of expected course material delivery systems for creating a virtual class such that lecturer and student which are separated at long distance can engage a learning activity as well as face to face learning system. For this reason, the service availability and quality should be able to guaranteed and fulfilled. In this research, we analyze QoS of video conferencing between main campus and sub campus as the implementation of distance learning system in laboratory scale. Our experimental results show that the channel capacity or bandwidth of WAN connection between main campus and sub campus at 128 kbps is able to generate the throughput of video transmission and reception at 281 kbps and 24 kbps, respectively. Meanwhile, throughput of audio transmission and reception is 64 kbps and 26 kbps with the number of total packet loss for video and audio transmission is 84.3% and 29.2%, respectively. In this setting, the total jitter for video and audio transmission is 125 ms and 21 ms, respectively. In this case, there is no packet loss for traffic transmitting and receiving with jitter is not more than 5 ms. We also implemented QoS using Trust CoS model dan Trust DSCP for improving the quality of service in term of jitter up to 12.3% and 22.41%, respectively.Keywords: quality of service, throughput, delay, jitter, packet loss, Trust CoS, Trust DSCP

Penelitian ini bertujuan menganalisis efektivitas perlindungan hukum terhadap guru dalam melakukan tindakan pendisiplinan siswa berdasarkan Undang-Undang Nomor 14 Tahun 2005 tentang Guru dan Dosen. Latar belakang penelitian ini adalah meningkatnya kasus kriminalisasi guru akibat kesalahpahaman masyarakat terhadap tindakan disiplin di sekolah. Secara normatif, guru memiliki legitimasi hukum untuk mendidik dan menegakkan disiplin, namun praktik di lapangan menunjukkan masih sering muncul tuduhan pelanggaran hak anak. Penelitian menggunakan pendekatan yuridis normatif dengan sifat deskriptif-analitis melalui kajian peraturan, literatur, serta data empiris dari 25 guru di wilayah DKI Jakarta. Hasil menunjukkan 72% guru merasa takut memberikan sanksi disiplin karena khawatir dilaporkan orang tua, sementara hanya 20% yang pernah mendapat pendampingan hukum dari organisasi profesi. Hal ini mengindikasikan adanya kesenjangan antara perlindungan normatif dalam UU No. 14 Tahun 2005 dan implementasinya. Perlindungan hukum masih bersifat formalistik tanpa mekanisme pelaksanaan yang jelas, diperburuk oleh tumpang tindih dengan UU Perlindungan Anak serta ketiadaan standar nasional mengenai batas tindakan disiplin edukatif. Pasal 39 ayat (2) UU No. 14 Tahun 2005 memang memberi jaminan perlindungan hukum, tetapi tanpa peraturan pelaksana yang tegas, menyebabkan ketidakpastian hukum bagi guru. Faktor penyebab lemahnya perlindungan meliputi rendahnya literasi hukum, minimnya dukungan kelembagaan, dan belum adanya sistem pendampingan hukum di sekolah. Penelitian merekomendasikan pembentukan regulasi khusus, penerapan restorative justice, serta pembentukan Unit Layanan Hukum Guru agar perlindungan hukum menjadi substantif, terintegrasi, dan partisipatif demi menciptakan sistem pendidikan yang adil dan bermartabat.
