Abstract

In the era of Industry 4.0, optimizing fluid flow systems in smart factories is essential to improve energy efficiency and operational stability. Traditional Computational Fluid Dynamics (CFD) simulations provide accurate fluid flow analysis but require extensive computational resources and long processing times, making real-time applications challenging. To address this limitation, this study aims to develop an AI-based predictive model for CFD simulations, utilizing Convolutional Neural Networks (CNN) and Extreme Gradient Boosting (XGBoost) to accelerate the estimation of fluid flow characteristics in industrial environments. The research methodology involves generating CFD simulation datasets, preprocessing data, and training AI models to predict key fluid parameters such as pressure, velocity, and temperature. The evaluation results show that CNN achieves a Mean Squared Error (MSE) of 0.0025 and a Root Mean Squared Error (RMSE) of 0.05, outperforming XGBoost, which records an MSE of 0.0030 and an RMSE of 0.055. Moreover, CNN predicts fluid dynamics in just 15.2 seconds, while XGBoost achieves results in 10.5 seconds, compared to the 1200.5 seconds required by traditional CFD simulations. These findings highlight the potential of AI in reducing computation time by over 98%, making real-time fluid flow analysis feasible in industrial settings. This study contributes to the advancement of AI-integrated CFD modeling, demonstrating that AI can significantly enhance the efficiency of fluid dynamics analysis without compromising accuracy. Future research should focus on expanding AI models to handle more complex flow conditions and integrating AI with smart factory design tools for real-time optimization

Abstract

Pencemaran air oleh zat pewarna sintetis seperti metilen biru menjadi permasalahan lingkungan yang serius karena sifatnya yang toksik dan resisten terhadap degradasi biologis. Penelitian ini bertujuan untuk membandingkan kinerja adsorpsi karbon aktif dari dua jenis biomassa kelapa sawit yaitu cangkang dan tandan kosong kelapa sawit terhadap metilen biru. Kedua bahan dikarbonisasi pada suhu 400 °C selama 1 jam, kemudian diuji kemampuan adsorpsinya pada tiga variasi waktu kontak (5, 10, dan 15 menit). Analisis dilakukan menggunakan spektrofotometri UV-Vis pada panjang gelombang 659 nm untuk menentukan nilai absorbansi sebelum dan sesudah adsorpsi. Hasil menunjukkan bahwa efisiensi penurunan absorbansi meningkat seiring waktu kontak, dengan efisiensi tertinggi pada menit ke-15, karbon aktif dari tandan menunjukkan efisiensi tertinggi sebesar 79,91%, sedangkan cangkang mencapai 77,50%. Karbon aktif dari tandan kosong kelapa sawit menunjukkan kinerja terbaik diikuti oleh cangkang kelapa sawit. Temuan ini menunjukkan bahwa biomassa kelapa sawit dapat dimanfaatkan sebagai bahan baku karbon aktif yang efektif, ramah lingkungan, dan berpotensi diterapkan dalam pengolahan limbah cair industri.

Abstract

Pemanfaatan limbah biomassa kelapa sawit sebagai bahan baku material fungsional berpotensi memberikan solusi berkelanjutan dalam pengelolaan limbah dan pengembangan teknologi sensor. Penelitian ini bertujuan untuk mengkarakterisasi gugus fungsi permukaan dari arang cangkang, tandan kosong, dan campuran keduanya melalui spektroskopi FTIR, guna mengevaluasi kelayakannya sebagai prekursor dalam sintesis komposit reduced Graphene Oxide (rGO)–Fe₃O₄ untuk aplikasi sensor magnetik geofisika. Sampel arang diperoleh melalui pirolisis pada suhu 400 °C selama 1 jam, kemudian dianalisis pada rentang spektrum 400–4000 cm⁻¹. Hasil menunjukkan bahwa arang campuran menampilkan struktur aromatik C=C paling dominan (%T 80% pada 1585 cm⁻¹), kandungan gugus karbonil (C=O) yang rendah (%T 90,7%), dan gugus eter/alkohol (C–O) yang cukup sebagai situs ikatan Fe₃O₄. Interaksi termokimia antara lignin dalam cangkang dan selulosa dalam tandan menghasilkan atmosfer reduktif internal yang meningkatkan kualitas rGO tanpa memerlukan perlakuan kimia agresif. Dengan kombinasi tersebut, arang campuran menawarkan kestabilan struktural, konduktivitas, dan kompatibilitas kimiawi yang superior dibandingkan bahan tunggal. Hasil ini menunjukkan bahwa limbah arang kelapa sawit, khususnya dalam bentuk campuran, sangat potensial sebagai prekursor lokal untuk pengembangan sensor magnetik berbasis nanokomposit yang ramah lingkungan dan efisien.

Abstract

Salah satu daerah yang rawan terkena banjir berdasarkan data Badan Penanggulangan Bencana Daerah (BPBD) Kota Malang adalah Kelurahan Gadingkasri, Kecamatan Klojen, Kota Malang. Kelurahan ini memiliki bangunan rumah yang padat terdiri dari rumah penduduk hingga kos-kosan untuk mahasiswa dan pendatang. Kepadatan tersebut menyebabkan daerah ini sering mengalami bencana banjir pada musim penghujan ketika curah hujan tinggi. Oleh karena itu, perlu adanya teknologi rekayasa yang dapat dimanfaatkan untuk menanggulangi kejadian tersebut, salah satunya membuat lubang resapan biopori-smart light untuk mengurangi debit air pada saat curah hujan tinggi dan sekaligus menjadi penerangan jalan. Teknologi ini sangat efektif diaplikasikan pada lahan sempit dan juga dapat digunakan sebagai bahan pencahayaan yang hemat energi karena menggunakan tenaga cahaya matahari. Lampu biopori dilengkapi dengan katoda dan anoda yang tersimpan didalam biopori.

Abstract

Based on the seasons in Indonesia, tobacco is classified into two types: cigar tobacco (Na-Oogst) and cigarette or kretek tobacco (Voor-Oogst). Tobacco seeds contain around 36-41% oil, which has the potential to be a renewable energy source. Biodiesel is one of the renewable alternative energy sources that has received much attention because it is a clean and green energy. Biodiesel is produced from triglycerides through a transesterification reaction with homogeneous and heterogeneous catalysts. Heterogeneous catalysts are more attractive because they can be regenerated and are environmentally friendly. The advantages of this catalyst are that it has good catalytic activity due to its large surface area and superior stability. Zeolite H-ZSM-5 appears as a solid acid catalyst with a promising microporous structure for esterification and transesterification reactions. In this study, TiO2 doping was added to improve the performance of the H-ZSM-5 catalyst. TiO2 is a leading photocatalyst because it has chemical, biological, and non-toxic stability. Furthermore, to determine the success of the synthesis of H-ZSM-5/TiO2 as a nanocatalyst, XRD, FTIR, SEM-EDX Mapping characterization was carried out. The results showed that the addition of TiO2 which has a particle size distribution of 46.07 nm in the synthesis of H-ZSM-5/TiO2 did not cause changes in structure and degree of crystallinity. The experimental parameters of transesterification that were varied were catalyst concentration. The results of the transesterification reaction yielded the highest methyl ester of 87.5% at optimum reaction conditions and a catalyst concentration of 2% w/w with a molar ratio of oil and methanol (1:12). The synthesized methyl ester has a characterization value that enters the range of SNI biodiesel values, so that the synthesized methyl ester has the potential to be used as biodiesel. We hope that this research can inspire researchers related to heterogeneous nanocatalyst research that is more efficient and rational and has good stability in the production of sustainable renewable fuels.
