Abstract

Pabrik biogasoline ini dirancang untuk memanfaatkan karet lateks kering sebagai bahan baku utama melalui proses fast pyrolysis yang dilanjutkan dengan catalytic cracking menggunakan katalis HZSM-5. Pemilihan bahan baku karet didasarkan pada ketersediaannya yang melimpah di Provinsi Sumatera Selatan, khususnya di wilayah Ogan Komering Ilir, yang merupakan salah satu daerah dengan produktivitas karet tertinggi di Indonesia. Proses fast pyrolysis berfungsi untuk menguraikan senyawa polimer karet menjadi fraksi cair berupa bio oil, sedangkan tahap catalytic cracking dilakukan untuk mengkonversi bio-oil menjadi fraksi hidrokarbon ringan dengan rentang karbon C5–C12 yang memiliki karakteristik serupa dengan bensin fosil. Pabrik direncanakan memiliki kapasitas produksi sebesar 128.000 kL per tahun dengan lokasi yang dipilih berdasarkan ketersediaan bahan baku, kemudahan akses transportasi, serta dukungan utilitas dan infrastruktur di kawasan industri Sumatera Selatan. Tahapan perancangan meliputi penentuan spesifikasi bahan baku dan produk, seleksi teknologi dan kondisi operasi, perhitungan neraca massa serta neraca energi, analisis Hazard and Operability (HAZOP), perancangan Piping and Instrumentation Diagram (P&ID), serta kajian ekonomi dan lingkungan untuk menilai kelayakan pembangunan pabrik. Hasil perancangan ini diharapkan dapat menjadi salah satu solusi dalam mendukung transisi energi nasional menuju sumber energi terbarukan, mengurangi ketergantungan terhadap bahan bakar fosil, serta meningkatkan nilai tambah komoditas karet alam melalui diversifikasi pemanfaatan menjadi bahan bakar ramah lingkungan yang berkelanjutan.

This biogasoline plant is designed to utilize dry natural latex rubber as the main raw material through a fast pyrolysis process followed by catalytic cracking using the HZSM-5 catalyst. The selection of rubber as the feedstock is based on its abundant availability in South Sumatra Province, particularly in the Ogan Komering Ilir region, which is one of the areas with the highest rubber productivity in Indonesia. The fast pyrolysis process functions to decompose the polymer chains of rubber into liquid fractions in the form of bio-oil, while the catalytic cracking stage converts the bio-oil into light hydrocarbon fractions within the carbon range of C5–C12, possessing characteristics similar to fossil gasoline. The plant is designed with a production capacity of 128,000 kL per year, with the chosen location determined by the availability of raw materials, accessibility of transportation, and supporting utilities and infrastructure within the industrial zone of South Sumatra. The design stages include determining the specifications of raw materials and products, selecting suitable technology and operating conditions, performing mass and energy balance calculations, conducting Hazard and Operability (HAZOP) analysis, designing the Piping and Instrumentation Diagram (P&ID), and carrying out economic and environmental feasibility assessments. The result of this design is expected to serve as a potential solution in supporting the national energy transition toward renewable sources, reducing dependence on fossil fuels, and enhancing the added value of natural rubber commodities through diversification into sustainable and environmentally friendly fuel production.
