Synthesis of A Sustainable Sago-Based Value Chain via Fuzzy Optimisation Approach

Abstract

Sago starch is one of the staple foods for human, especially in Asia’s Region. It can be produced via sago starch extraction process (SSEP). During the SSEP, several types of sago wastes are generated such as sago fiber (SF), sago bark (SB) and sago wastewater (SW). With the increase in production of existing factories and sago mills, the sago industrial practice in waste disposal management is gaining more attention, thus implementation of effective waste management is vital. One of the promising ways to have effective waste management is to create value out of the sago wastes. In a recent study, sago-based refinery, which is a facility to convert sago wastes into value-added products (e.g., bio-ethanol and energy) was found feasible. However, the conversion of other value added products from sago wastes while considering the environmental impact has not been considered in sago value chain. Therefore, an optimum sago value chain, which involved conversion activities of sago wastes into value-added products, is aimed to be synthesised in this work. The optimum sago value chain will be evaluated based on profit and carbon emissions using fuzzy-based optimisation approach via a commercial optimisation software, Lingo 16.0. To illustrate the the developed approach, an industrial case study has been solved in this work.

Pengaruh Nilai Tambah dan Efisiensi Pemasaran Sagu Terhadap Pendapatan Pengolah Sagu di Kabupaten Konawe Provinsi Sulawesi Tenggara Indonesia

“…Peningkatan pendapatan pengolah sagu dapat dilakukan dengan memberikan pemahaman kepada petani agar pada saat panen, komoditi yang dihasilkan tidak langsung dijual, tetapi terlebih dahulu hasil panen diolah kemudian di jual dan limbah hasil pengolahan sagu dapat digunakan sebagai sumber daya lokal berpotensi untuk digunakan sebagai sumber energi pada pakan tambahan untuk sapi potong (Tiro et al 2018). Lebih lanjut Chong et al (2018) rantai nilai sagu secara optimal melalui konversi limbah sagu menjadi produk bernilai tambah atau limbah sagu dapat diolah menjadi pupuk organik bernilai tambah (Elton et al, 2014) Efisiensi pemasaran (processor's share) adalah bagian harga yang diterima produsen sehingga dapat meningkatkan pendapatan petani. Semakin besar bagian harga yang diterima Jurnal Ilmiah Membangun Desa dan Pertanian (JIMDP) 2020: 5(1):19-26 eISSN: 2527-2748 produsen menunjukkan pemasaran komoditas pertanian semakin efisien.…”

Hybrid Resource Environmental Value Chain Model Based on a Discrete Time Algorithm

“…The conditions for the existence and development of an industrial enterprise must create value for its shareholders and other interest groups. The process of creating value is divided into a series of different but interrelated economic activities, or "value-added activities," which constitute the enterprise "value chain" [2]. In the process of enterprise operation, we pay more attention to the economic benefits of the enterprise and ignore the environmental protection and the rational use of resources, so there are environmental pollution, resource shortage, and other problems.…”

Modelling supply chain risks and their impacts on the performance of the sago starch agro-industry

“…Logs are tied and IJPPM 71,6 transported through rivers/straits to sago processors (mills) located on river strait banks. At the mill, several processing stages are required to produce sago starch, including log debarking, rasping, extraction, drying and packaging (Pratama et al, 2018;Chong et al, 2018). Most sago starch is shipped by vessel to Cirebon port, West Java, Indonesia (Ehara et al, 2018).…”
