Abstract
Industri pertahanan memainkan peran penting dalam mencapai kemandirian teknologi militer. Meskipun Indonesia telah memulai produksi propelan sendiri, Indonesia masih mengimpor propelan roket, terutama jenis EDB (Extruded Double Base). Salah satu upaya untuk meningkatkan kualitas propelan adalah dengan menggunakan proses ekstrusi. Proses ini melibatkan tiga tahap utama: pencampuran, pengerolan, dan ekstrusi. Tahap ekstrusi memiliki peran kritis dalam menentukan karakteristik fisik dan termal propelan, seperti kekakuan, laju pembakaran, stabilitas termal, dan lainnya. Parameter ekstrusi yang tepat akan menghasilkan propelan dengan karakteristik fisik dan termal yang baik. Dalam manufaktur ekstrusi propelan, bahan awal adalah pasta basah propelan yang bersifat pseudoplastic. Variabel pada penelitian ini adalah variabel tekanan dan temperatur, dengan variasi tekanan 40 dan 60 psi, dan variasi temperatur 30°C, 50°C, 70°C. Dari penelitian ini diperoleh bahwa variasi tekanan berpengaruh pada karakteristik fisik dan termal, sementara variasi temperatur tidak memberi pengaruh signifikan terhadap karakteristik fisik, tetapi berpengaruh secara signifikan terhadap karakteristik termal. Hasil penelitian ini juga menghasilkan kandidat propelan EDB yang memenuhi base dan referensi dengan spesimen kode PT-23, menggunakan variasi tekanan 60 psi dan temperatur 70°C dan menghasilkan nilai hardness sebesar 65,8 Shore A, densitas sebesar 1,51 g/cc, stabilitas termal sebesar 182°C, laju pembakaran sebesar 4,43 mm/s, dan nilai kalor sebesar 1622 Kkal/Kg.

The defense industry plays a crucial role in achieving military technology independence. Although Indonesia has started producing its own propellants, it still imports rocket propellants, particularly the EDB (Extruded Double Base) type. One effort to improve propellant quality is by using the extrusion process. This process involves three main stages: mixing, rolling, and extrusion. The extrusion stage plays a critical role in determining the physical and thermal characteristics of the propellant, such as stiffness, burn rate, thermal stability, and others. Proper extrusion parameters will result in propellants with good physical and thermal characteristics. In propellant extrusion manufacturing, the initial material is a wet propellant paste that is pseudoplastic. The variables in this study are pressure and temperature, with pressure variations of 40 and 60 psi, and temperature variations of 30°C, 50°C, and 70°C. The study found that pressure variations affect physical and thermal characteristics, while temperature variations do not significantly affect physical characteristics but significantly influence thermal characteristics. The study also produced an EDB propellant candidate that meets the base and reference standards with specimen code PT-23, using a pressure variation of 60 psi and a temperature of 70°C, resulting in a hardness value of 65.8 Shore A, a density of 1.51 g/cc, thermal stability of 182°C, a burn rate of 4.43 mm/s, and a calorific value of 1622 Kcal/Kg.
