This present study to determine the potential of Neptunia oleracea as a phytoremediation agent for petroleum liquid waste in terms of various parameters such as physical temperature, and chemical parameters, namely pH, sulfide, and ammonia. Crude oil liquid waste is a hazardous waste if discharged directly into the environment, especially water. In this research, a method of biological treatment of petroleum liquid waste was used by utilizing aquatic plants, namely Neptunia oleracea. Phytoremediation is a way to treat waste that still contains contaminants thus levels can be minimized and even accumulated by various types of plants. This phytoremediation technique uses a simple bioreactor with various concentrations of petroleum liquid waste, namely control (0% waste), 10% waste, 20% waste, and 30% waste. The results of this study can be seen that the Neptunia oleracea plant is able to survive in petroleum liquid waste with a treatment time of approximately 3 weeks. In testing the levels of ammonia and sulfide after treatment showed fluctuating results from week to week. This is a response from Neptunia oleracea which uses these compounds in its metabolic processes. The ability of Neptunia oleracea to reduce sulfide and ammonia levels indicates that this plant can be used as a phytoremediation agent for petroleum liquid waste.
Selama masa pandemi covid 19, sekolah dituntut menggunakan media daring dalam proses kegiatan belajar mengajar kepada siswa. Kondisi yang terjadi kurangnya kegiatan pelatihan yang diikuti oleh guru-guru dan karyawan khusunya dalam pemanfaatan IT terkait proses pembelajaran dengan menggunakan media daring berupa zoom dan google meet. Oleh Karena itu perlu diadakanya pelaksanaan kegiatan pengabdian kepada guru-guru dan karyawana yang ada di sekolah dasar negeri 23 palembang dengan tujuan memberi wawasan bagi guru-guru dan karyawan sekolah dasar negeri 23 palembang mengenai metode pembelajaran jarak jauh secara daring seperti zoom dan google meet, memberikan kemampuan bagi guru-guru dan karyawan sekolah dasar negeri 23 palembang untuk dapat menguasai dan menggunakan zoom dan google meet, sebagai sarana untuk meningkatkan kompetensi guru-guru dan karyawan sekolah dasar negeri 23 palembang, meningkatkan efektivitas dan efisiensi proses belajar mengajar dilingkungan sekolah dasar negeri 23 palembang, sebagai sarana positif untuk mengenalkan Universitas Sriwijaya pada masyarakat luas, hasil akhirnya guru-guru mampu mengaplikasikan kepada siswa-siswa yang ada dilingkungan sekolah dasar negeri 23 palembang. Kata kunci: Sekolah Dasar Negeri 23 Palembang, Media Daring Zoom, Media Daring Google Meet
