Abstract
Kenaf fiber from the kenaf plant is the excellent raw material for industry because of the various diversified products it produces. To develop sustainable kenaf fiber, information is needed on the strengths and weaknesses of kenaf cultivation systems with respect to productivity and environmental impact. Therefore, a comprehensive environmental and economic impact assessment was conducted from cultivating kenaf to kenaf fiber. The environmental impact assessment uses the Life Cycle Assessment (LCA) method and economic calculations from the life cycle of kenaf to kenaf fiber to collectors use the Life Cycle Cost (LCC) method. The calculation of environmental impacts is in accordance with the stages of ISO 14040, using a single score assessment. The LCA results show that the treatment stage is the highest contributor of the three groups of impact categories. The highest to the lowest in the impact category group that was influenced by the treatment stage were resources with a value of 21.4 mPt, human health with a value of 8.76 mPt, and ecosystem quality with a value of 1.91 mPt. The cost identified through the LCC is Rp. 6,088,468,333, NVP and B/Cnet are positive. The results of the sensitivity analysis if there is a reduction in production> 6%, the business is still profitable and can be run.

Summary
Model LCA Ruang lingkup tahap LCA pada penelitian ini adalah cradle to gate, yang mencakup semua proses hulu di produksi serat kenaf. Ruang lingkup siklus hidup pertumbuhan kenaf sampai menjadi serat kenaf pada penelitian ini meliputi tahap pembibitan kenaf, pemeliharaan tanaman kenaf yang meliputi pemupukan dan pemberian pestisida, pasca panen yang terdiri dari perendaman batang kenaf, penyeratan kulit batang kenaf, dan pencucian, dan tahap terakhir adalah pengiriman serat kenaf ke pengepul. 2. Life Cycle Inventory (LCI) Langkah kedua LCA ini adalah mengelompokkan dan mengompilasi input dan output dari masing-masing tahapan yang menjadi ruang lingkup penelitian. Data input dan output diperoleh dari informasi ketua kelompok tani lahan bonorowo, Laren. Model LCC Pada tahap perhitungan biaya menggunakan metode LCC maka semua biaya yang dikeluarkan selama proses penanaman kenaf sampai menjadi serat kenaf diperhitungkan. Analisis sensitivitas diasumsikan dari data masa lalu yaitu penurunan produksi sebesar 6%
