Abstract

Transformasi energi di sektor industri mendorong adopsi bahan bakar alternatif yang lebih ramah lingkungan, seperti wood pellet, untuk menggantikan sebagian penggunaan batubara. Salah satu metode yang diterapkan adalah sistem co-firing, yaitu pembakaran campuran batubara dan biomassa dalam proporsi tertentu. PT. Dayasa Aria Prima sebagai perusahaan industri kertas menanggapi kebijakan ini dengan melakukan modifikasi sistem penyimpanan dan pengumpanan bahan bakar, khususnya pada struktur coal silo dan feeder conveyor. Perubahan dilakukan untuk meningkatkan kapasitas penyimpanan dari 20 ton menjadi 30 ton dan menyesuaikan desain sistem pengangkutan material agar kompatibel dengan karakteristik fisik campuran batubara dan wood pellet. Laporan ini menyajikan hasil perancangan dan simulasi struktur coal silo serta sistem belt conveyor sebagai tugas khusus dalam program magang industri di PT. Intan Timur Energi. Metodologi yang digunakan meliputi studi literatur, observasi langsung, pengambilan data teknis, pemodelan 3D menggunakan perangkat lunak CAD, serta simulasi pembebanan struktur menggunakan SolidWorks. Komponen utama coal silo dirancang dengan mempertimbangkan faktor distribusi beban, stabilitas struktural, dan kemudahan pemeliharaan. Material konstruksi menggunakan baja ASTM A36 dengan konfigurasi H-Beam dan C-Channel sebagai elemen penopang utama. Salah satu aspek penting dalam desain silo adalah total volume silo. Berdasarkan hasil perhitungan, diperoleh kapasitas penyimpanan efektif sebesar 34 ton dengan distribusi volume bahan bakar 70% batubara dan 30% wood pellet. Di sisi lain, sistem feeder belt conveyor yang berfungsi sebagai pengangkut dan pengumpan material dari silo menuju ruang pembakaran boiler juga mengalami redesain, meliputi penyesuaian lebar belt, dimensi roller, daya motor, dan kapasitas angkut. Desain conveyor memperhitungkan jenis material curah, sudut kemiringan, serta kecepatan operasional agar proses feeding berlangsung stabil dan berkesinambungan. Melalui proyek ini, diperoleh pemahaman mendalam mengenai integrasi antara desain struktur penyimpanan dan sistem transportasi material dalam mendukung sistem pembakaran bahan bakar campuran. Perancangan ini tidak hanya memenuhi kebutuhan teknis, tetapi juga mendukung efisiensi energi dan keberlanjutan industri. Diharapkan laporan ini dapat menjadi referensi bagi pengembangan sistem coal handling berbasis conveyor di industri boiler dan energi terbarukan.

The energy transition in the industrial sector drives the adoption of more environmentally friendly alternative fuels, such as wood pellets, to partially replace coal usage. One of the methods implemented is the co-firing system, which involves burning a mixture of coal and biomass in specific proportions. PT Dayasa Aria Prima, a paper manufacturing company, responded to this policy by modifying its fuel storage and feeding systems, specifically the coal silo structure and feeder conveyor. These modifications were carried out to increase the storage capacity from 20 tons to 30 tons and to adapt the material transport system design to ensure compatibility with the physical characteristics of the coal and wood pellet mixture. This report presents the design and simulation results of the coal silo structure and the belt conveyor system as a special assignment within the industrial internship program at PT Intan Timur Energi. The methodology used includes literature study, direct observation, technical data collection, 3D modeling using CAD software, and structural load simulation using SolidWorks. The main components of the coal silo were designed by considering load distribution, structural stability, and ease of maintenance. The construction material utilizes ASTM A36 steel with H-Beam and C-Channel configurations as the primary supporting elements. One important aspect of the silo design is the total silo volume. Based on the calculation results, an effective storage capacity of 34 tons was obtained, with a fuel volume distribution of 70% coal and 30% wood pellets. In addition, the feeder belt conveyor system, which transports and feeds material from the silo to the boiler combustion chamber, was redesigned by adjusting the belt width, roller dimensions, motor power, and conveying capacity. The conveyor design considers the type of bulk material, inclination angle, and operational speed to ensure a stable and continuous feeding process. Through this project, a comprehensive understanding was gained regarding the integration between storage structure design and material handling systems in supporting blended fuel combustion systems. This design not only meets technical requirements but also supports energy efficiency and industrial sustainability. It is expected that this report will serve as a reference for the development of conveyor-based coal handling systems in the boiler and renewable energy industries.
