Abstract

The use of heavy metals including manganese (Mn) in various industrial applications such as mining and metal processing has triggered water pollution and caused a negative impact on human health. This study aims to evaluate the adsorbent properties activated by sodium hydroxide from oil palm frond waste for Mn(II) adsorption from the water via a fixed-bed column at flow rates of 5, 10, and 15 mL/min. The morphology analysis exhibited high pore development in the adsorbent after the activation process using sodium hydroxide. Similar to the results of functional group analysis, the activated adsorbent indicated an increase in oxygen-containing functional groups that are beneficial aspects in the adsorption process. In the continuous adsorption applications, a flow rate of 5 mL/min presented an optimum adsorption capacity of 36.58 mg/g compared to flow rates of 10 mL/min and 15 mL/min: 28.94 mg/g and 22.07 mg/g, respectively. The findings of the present work denote the utility and effectiveness of oil palm frond waste as an eco-friendly raw material for the fabrication of adsorbent with relatively favorable properties for Mn(II) adsorption.

Abstract

Saat ini, kecerdasan buatan (Artificial Intelligence) atau AI, memiliki pengaruh yang signifikan di berbagai bidang, termasuk dalam penerapan teknologi multimedia. AI juga memberikan dampak nyata terhadap berbagai bidang penerapannya, seperti di bidang pendidikan, kesehatan, industri kreatif, pemasaran digital, hingga sistem hukum. Integrasi AI memungkinkan multimedia menjadi lebih interaktif, adaptif, dan efisien dalam menyampaikan informasi serta meningkatkan pengalaman pengguna. Dibutuhkan penelitian yang mendalam untuk mengetahui sejauh mana pengaruh penerapan AI dalam teknologi multimedia terhadap masing-masing bidang tersebut. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis peran AI dalam pengembangan teknologi multimedia pada berbagai bidang. Metode penelitian menggunakan Metode System Literature Review (SLR), untuk mengidentifikasi, mengevaluasi, dan mensintesis temuan-temuan ilmiah yang relevan dalam kurun waktu 2020–2025 dari berbagai studi terdahulu. Hasil kajian menunjukkan bahwa AI memiliki kontribusi yang luas dalam mempercepat inovasi multimedia, mulai dari bidang pendidikan, kesehatan, industri kreatif, sosial, hukum, hingga properti. Sistem multimedia interaktif dan otomatis ini didukung oleh Teknologi AI seperti Deep Learning (DL), Computer Vision, Natural Language Processing (NLP), dan Generative Adversarial Networks (GAN). Teknolgi AI yang paling banya dipakai adalah Teknologi Deep Learning. Di bidang pendidikan, AI digunakan untuk pengembangan konten pembelajaran adaptif dan visualisasi interaktif. Di sektor kesehatan, AI diaplikasikan dalam sistem diagnosis berbasis citra dan media edukatif pasien. Sementara itu, bidang sosial dan hukum memanfaatkan AI dalam analisis visual, pendeteksian konten berbahaya, serta pemantauan media. Penelitian ini menyimpulkan bahwa integrasi AI dan multimedia berperan penting dalam meningkatkan efisiensi, akurasi, serta kualitas informasi visual dan audio yang digunakan secara luas pada berbagai bidang.
