Perancangan Tata Letak dan Model 3D Pabrik Silika Bubuk dari Limbah Abu Sekam Padi di SPP BULOG Subang

Abstract

Sentra Penggilingan Padi (SPP) BULOG Subang menghadapi masalah penumpukan limbah abu sekam padi di area pabrik. Limbah abu sekam padi memiliki kandungan silika (SiO2) yang tinggi sehingga dapat dimanfaatkan sebagai bahan baku silika bubuk. Perancangan tata letak fasilitas pabrik menjadi tantangan bagi SPP BULOG Subang untuk menjamin efisiensi dan keberlanjutan operasional pabrik. Oleh karena itu, dilakukan perancangan tata letak fasilitas pabrik silika bubuk berbasis limbah abu sekam padi dengan pendekatan Systematic Layout Planning (SLP) dan algoritma Blocplan. Tahapan perancangan meliputi identifikasi PQRST, penyusunan Activity Relationship Chart (ARC), perhitungan kebutuhan luas ruang, dan perancangan alternatif layout menggunakan algoritma Blocplan. Total luas fasilitas yang dirancang sebesar 1.187 m2 , yang dapat dibangun secara optimal pada lahan kosong seluas 4.290 m2 di belakang pabrik. Hasil perancangan menunjukkan tata letak terbaik berdasarkan nilai adjacency score sebesar 0,70, rscore sebesar 0,77, dan rel-dist score sebesar 88. Perancangan selanjutnya divisualisasikan dalam bentuk model 3D menggunakan SketchUp sebagai prototipe akhir fasilitas pabrik yang efisien, fungsional, dan implementatif.

The Modern Rice Milling Unit (SPP) BULOG Subang is facing an issue with the accumulation of rice husk ash waste within its factory area. This waste contains a high concentration of silica (SiO2), making it a potential raw material for powdered silica production. Designing an efficient and sustainable facility layout presents a challenge for SPP BULOG Subang to support continuous operational activities. Therefore, a facility layout design for a powdered silica plant utilizing rice husk ash waste was carried out using the Systematic Layout Planning (SLP) approach combined with the Blocplan algorithm. The design stages included identifying PQRST factors, developing an Activity Relationship Chart (ARC), calculating space requirements, and generating layout alternatives through the Blocplan algorithm. The total designed facility area is 1.187 m², which can be optimally constructed on a 4.290 m² vacant plot located behind the existing plant. The final layout design yielded the highest performance with an adjacency score of 0,70, an r-score of 0,77, and a rel-dist score of 88. The proposed layout was subsequently visualized in 3D models using SketchUp as a final prototype of an efficient, functional, and implementable plant facility.
