ABSTRAK Anggra Setiyo Irnanto, 2024, Strategi Pengolahan Waste Carbon Guna Meningkatkan Nilai Tambah Pada Industri Bahan Tambahan Pangan (BTP) (Proyek: PT. WXYZ). Tesis, Program Studi Teknik Industri, Program Pascasarjana ITN Malang, Pembimbing: (I) Ir. Fourry Handoko, ST., SS., MT., Ph.D., IPU., ASEAN.Eng (II) Dr. Dimas Indra Laksamana, ST., MT. PT. WXYZ merupakan perusahaan yang bergerak dibidang Bahan Tambahan Pangan (BTP) berupa vetsin. Perusahaan dalam mengeksploitasi sumber daya energi secara besar besaran untuk pengembangan industrinya berdampak pada lingkungan yaitu berupa waste industri yang diakibatkan oleh proses produksi. Salah satu waste PT. WXYZ yaitu waste active carbon yang dihasilkan dari hasil adsorpsi produk inline yang berupa larutan netral. Permasalahan yang ada yaitu sisa waste carbon di solar dryer dan industri tidak mendapatkan nilai tambah. Adapun strategi pengolahan dengan menggunakan integrasi Taguchi-Value Engineering. Siklus PDCA efektif mengidentifikasi masalah dengan pendekatan yang mengacu pada Responsible Waste Management Hierarchy dan dibatasi melaksanakan eksperimen 3R (reduce, reuse dan recycle). Sedangkan desain eksperimen menggunakan taguchi karena lebih cost effective dari DOE lainnya serta analisis biaya dengan Value Engineering. Penelitian ini termasuk jenis metode kuantitatif dekriptif dan eksperimental. Pelaksanaan proyek konsep 3R dengan mendesain susunan eksperimen taguchi. Sehingga didapatkan desain optimasi reduce yaitu [waste carbon] : 10 gr/dl; [active carbon] : 0.2 g/dl; temp : 60°C dengan nilai n-gain 0.54 kategori improve sedang; desain optimasi reuse yaitu waste carbon basah ; [biochar] : 25%; cahaya : terang dengan nilai n-gain 4.49 kategori improve tinggi dan desain optimasi recycle yaitu waste carbon kering ; [perekat] : 25%; tekanan : 2 menit dengan nilai n-gain 1.45 kategori improve tinggi. Sedangkan analisis biaya berdasarkan value engineering didapat prioritas ke-1 yaitu minimalisir karbon aktif (Reduce) memiliki bobot tertinggi 373.33 yang potensi menghemat bahan baku karbon sebesar 51.6% (Rp. 7.284.200.000,00/th dari total penerimaan). Prioritas ke-2 diolah menjadi produk media tanam Biochar (reuse) memiliki bobot 253.33 dengan nilai tambah 8.2% (keuntungan Rp 76,463,416.84/th dari total 150 kg biochar/hari), nilai NPV > project cost (+) sebesar Rp. 279,768,175.77, nilai BEP sebesar Rp. 512,564,245.00 dan ROI sebesar 63.2%. Prioritas alternatif ke-3 diolah menjadi produk briket bioarang (recycle) memiliki bobot 233.33 dengan nilai tambah 3.0% (Rp. 29,093,376.84/th dari total 150 kg briket/hari) nilai NPV > project cost (+) sebesar Rp 110,286,788.00, nilai BEP sebesar Rp. 770,740,120.01 dan ROI sebesar 15.6%.

ABSTRACT Anggra Setiyo Irnanto, 2024, Strategy of Waste Carbon Processing to Increase Added Value in the Food Additive Industry (BTP) (Project: PT. WXYZ). Thesis, Industrial Engineering Study Programme, ITN Malang Postgraduate Programme, Advisor: (I) Ir. Fourry Handoko, ST, SS, MT, Ph.D., IPU, ASEAN.Eng (II) Dr Dimas Indra Laksamana, ST., MT. PT WXYZ is a company engaged in the field of Food Additives (BTP) in the form of vetsin. The company in exploiting energy resources on a large scale for the development of its industry has an impact on the environment in the form of industrial waste caused by the production process. One of PT WXYZ's waste is waste active carbon produced from the adsorption of inline products in the form of a neutral solution. The existing problem is the remaining waste carbon in the solar dryer and the industry does not get added value. The processing strategy uses PDCA-Value Engineering integration. The PDCA cycle effectively identifies problems with an approach that refers to the Responsible Waste Management Hierarchy and is limited to carrying out 3R experiments (reduce, reuse and recycle). While the experimental design uses Taguchi because it is more cost effective than other DOEs and cost analysis with Value Engineering. This research is a descriptive and experimental quantitative method. Implementation of the 3R concept project by designing a taguchi experimental setup. So that the reduced optimisation design is obtained, namely [waste carbon] : 10 gr/dl; [active carbon]: 0.2 g/dl; temp: 60°c with an n-gain value of 0.54 medium improvement category; reuse optimisation design is wet waste carbon; [biochar]: 25%; light: bright with an n-gain value of 4.49 high improvement category and recycle optimisation design namely dry waste carbon; [adhesive]: 25%; pressure: 2 minutes with an n-gain value of 1.45 high improvement category. While the cost analysis based on value engineering obtained the 1st priority, namely minimising activated carbon (Reduce) has the highest weight of 373.33 which potential saves carbon raw materials by 51.6% (Rp. 7,284,200,000.00 / year from the total carbon revenue). The 2nd priority alternative processed into Biochar planting media products (reuse) has a weight of 253.33 with an added value of 8.2% (profit of Rp.76,463,416.84 / year from a total of 150 kg of biochar/day), NPV value > project cost (+) of Rp. 279,768,175.77, BEP value of Rp. 512,564,245.00 and ROI of 63.2%. The 3rd alternative priority is processed into biochar briquette products (recycle) has a weight of 233.33 with an added value of 3.0% (Rp. 29,093,376.84 / year from a total of 150 kg of briquettes / day), NPV> project cost (+) value of Rp. 110,286,788.00, BEP value of Rp. 770,740,120.01 and ROI of 15.6%.
