Abstract

Akhir tahun 2019, budidaya tumbuhan porang mulai dipandang oleh masyarakat. Umbi porang memiliki kandungan khusus, yaitu glukomanan. Glukomanan memiliki berbagai manfaat, seperti membantu mengurangi kolesterol darah, ramah bagi penderita diabetes, membantu program diet, dan memperlambat pengosongan perut. Tepung glukomanan memiliki banyak manfaat lainnya, tetapi masih sedikit produsen di Indonesia yang memproduksi tepung glukomanan dengan kemurnian di atas 80% atau food grade, yaitu hanya dua perusahaan.

Pra Desain Pabrik Tepung Glukomanan dari Umbi Porang (Amorphophallus oncophyllus) ini direncanakan mulai beroperasi pada tahun 2025 dengan kapasitas produksi sebesar 2.600 ton/tahun. Lokasi pabrik direncanakan berada di Desa Ngadirejo, Kecamatan Tanjunganom, Kabupaten Nganjuk, Jawa Timur. Kabupaten Nganjuk memiliki ketersediaan bahan baku sekitar 30.600 ton/tahun dan luas lahan sebesar 759 hektar. Dalam pemenuhan kapasitas tahunan, pabrik akan beroperasi secara kontinu selama 24 jam per hari dan 330 hari per tahun. Dengan bahan baku sebesar 328 kg/jam, dapat dihasilkan produk sebesar 189 kg/jam. Proses produksi umbi porang menjadi tepung glukomanan terbagi menjadi tiga tahapan proses. Tahapan pertama adalah pre-treatment umbi porang. Tahapan kedua meliputi pemurnian tepung porang. Tahapan ketiga adalah pengeringan dan pengecilan ukuran.

Pra Desain Pabrik Tepung Glukomanan dari Umbi Porang ini dirancang sebagai perusahaan yang berbadan hukum Perseroan Terbatas (PT) dengan sistem organisasi garis dan staf. Dalam pendirian pabrik dengan kapasitas produksi sebesar 2.600 ton/tahun, diperlukan modal investasi sebesar Rp172.078.332.625,8 dan total biaya produksi sebesar Rp645.505.732.180,1, dengan estimasi hasil penjualan sebesar Rp676.000.000.000,0 per tahun. Estimasi umur pabrik diperkirakan hingga 25 tahun dengan Internal Rate of Return (IRR) sebesar 14,02%, Pay Out Time (POT) selama 9 tahun, dan Break-Even Point (BEP) sebesar 32%.

At the end of 2019, the cultivation of porang plants began to attract public attention. Porang tubers contain a special component, namely glucomannan. Glucomannan has several benefits, including helping reduce blood cholesterol levels, being suitable for people with diabetes, supporting dietary needs, and slowing gastric emptying. Glucomannan flour has many other benefits; however, there are still only a few producers in Indonesia, with only two companies producing glucomannan flour with a purity above 80% or food-grade quality.

The Pre-Plant Design of Glucomannan Flour from Konjac Tubers (Amorphophallus oncophyllus) is planned to start operating in 2025 with a production capacity of 2,600 tons/year. The plant is planned to be located in Ngadirejo Village, Tanjunganom District, Nganjuk Regency, East Java. Nganjuk Regency has a raw material availability of approximately 30,600 tons/year and a cultivated land area of 759 hectares. To meet the annual production capacity, the plant will operate continuously for 24 hours per day and 330 days per year. With a raw material feed rate of 328 kg/hour, the plant can produce 189 kg/hour of product. The production process for converting porang tubers into glucomannan flour is divided into three stages. The first stage is the pre-treatment of porang tubers. The second stage involves the purification of porang flour. The third stage consists of drying and size reduction.

The Pre-Plant Design of Glucomannan Flour from Konjac Tubers (Amorphophallus oncophyllus) is designed as a company incorporated as a Limited Liability Company (PT) with a line-and-staff organizational structure. To establish the plant with a production capacity of 2,600 tons/year, an investment capital of IDR 172,078,332,625.8 is required, with a total production cost of IDR 645,505,732,180.1 and estimated annual sales revenue of IDR 676,000,000,000.0. The estimated operating life of the plant is 25 years, with an Internal Rate of Return (IRR) of 14.02%, a Pay-Out Time (POT) of 9 years, and a Break-Even Point (BEP) of 32%.
