Abstract

In terms of hygiene and sanitation, ensuring the availability of qualified water for those purposes remains challenging to perform under certain conditions. Accordingly, efforts to provide simple water processing technology are ongoing and innovatively developed. This study displayed an innovative approach to producing coagulants for water processing by utilizing metal salts obtained synthetically from used beverage cans and iron plates through the electrolysis principle and characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Scanning Electron Microscopy - The Energy Dispersive X-ray (SEM-EDX), subsequently. After mixing with calcium hypochlorite and adding to water sample, subsequently, the coagulant showed the ability to reduce the turbidity level and several categories of impurities, i.e., nitrate, nitrite, dissolved Manganese, Cr6+ ion, and microbial levels. Future research and development in formulating coagulants derived from digested beverage cans and iron plate wastes hold significant potential to advance sustainable and efficient water treatment technologies, ensuring improved hygienic quality of fresh river water while contributing to waste valorization and environmental protection.

Abstract

Program magang merupakan salah satu bentuk implementasi pembelajaran berbasis pengalaman (experiential learning) yang dirancang untuk menjembatani kesenjangan antara teori yang diperoleh di bangku perkuliahan dengan praktik nyata di dunia kerja. Penelitian ini bertujuan untuk mengevaluasi kinerja mahasiswa magang dalam pelaksanaan program Magang Generasi Bertalenta (MAGENTA) BUMN di PT Dahana. Evaluasi ini dilakukan guna memperoleh gambaran menyeluruh mengenai kompetensi, kedisiplinan, tanggung jawab, serta kemampuan adaptasi mahasiswa selama kegiatan magang berlangsung. Metode penelitian yang digunakan adalah metode deskriptif kualitatif dengan pendekatan survei. Instrumen pengumpulan data berupa kuesioner tertutup yang disebarkan kepada pembimbing lapangan selaku penilai kinerja mahasiswa. Data yang diperoleh dianalisis untuk menilai efektivitas program magang dalam meningkatkan kemampuan profesional mahasiswa serta kontribusinya terhadap lingkungan kerja. Hasil penelitian menunjukkan bahwa secara umum mahasiswa magang memiliki kinerja yang baik, ditandai dengan tingkat kedisiplinan yang tinggi, rasa tanggung jawab terhadap tugas, dan kemampuan adaptasi yang cepat terhadap budaya kerja perusahaan. Program MAGENTA di PT Dahana terbukti memberikan dampak positif terhadap pengembangan kompetensi mahasiswa serta memperkuat hubungan kemitraan antara perguruan tinggi dan dunia industri.
