Abstract

Cassava is one of the third staple foods after rice and corn. However, cassava contains cyanogenic β-glucoside compounds in the form of linamarin compounds which have the potential to be hydrolyzed into HCN compounds (cyanide acid). In addition, cassava is included in foodstuffs that cannot be consumed directly, so it needs to be cooked. Therefore the purpose of this study was to determine the effect of the cooking process (boiling, steaming, and frying) on ​​the linamarin compound profile. The results of testing the linamarin profile using FTIR obtained linamarin vibrates at a wavelength of 4000-500 cm-1 with transmittance of 70-100%.

Abstract

Ubi jalar kuning dengan varietas benindo merupakan salah satu komoditas yang memiliki nilai jual di pasar ekspor, baik dalam produk segar maupun produk pure. Sortasi dan grading yang dilakukan untuk pemenuhan standar ekspor mengakibatkan adanya produk afkir yang tidak lolos seleksi, sehingga dapat dikembangkan menjadi produk turunan yaitu ice cone. Penelitian ini bertujuan untuk megetahui berapa besar harga pokok produksi dan nilai tambah terhadap produk ice cone dengan penambahan tepung ubi jalar manis. Sehingga dari penelitian ini diharapkan dapat memberikan inovasi, informasi, serta masukan untuk dijadikan peluang bagi para pelaku usaha industri pangan. Teknik analisa yang digunakan adalah menggunakan metode Hayami. Hasil penelitian menunjukkan bahwa pengolahan tepung ubi jalar manis sebagai produk ice cone memiliki nilai harga pokok produksi sebesar Rp. 44.914,9 dengan rasio nilai tambah sebesar 78% yang berada pada  indikator >40% . Artinya nilai tambah yang dihasilkan masuk dalam kategori tinggi. Hasil analisis nilai tambah yang tinggi menggambarkan bahwa usaha yang akan dijalankan mampu menciptakan nilai lebih besar dari input atau bahan baku yang dipakai dalam proses produksinya yang artinya berhasil dalam efisiensi dalam mengolah bahan baku sehingga menjadikan output lebih bernilai.

Abstract

Jember State Polytechnic has a fish canning teaching factory with a productivity of 7 q of fish per production. The canned fish product is a superior product, but the quality and type of products produced are low quality and less desirable. Therefore, product diversification is needed to increase the added value of canned fish. The fluctuating production capacity at teaching factory (TeFa) Fish Canning is an obstacle in determining production capacity according to market demand. The aim of this research is to diversify products and optimize fish canning products. This research was carried out using two methods, namely selecting superior products for TeFa fish canning using the Analytical Network Process (ANP) method and determining production capacity using the Fuzzy Inference System (FIS)-Tsukamoto method. The research results show that TeFa fish canning's superior product was determined by considering 4 criteria and 12 sub-criteria to produce tongkol balado with the highest weight value and followed by sardines with chili sauce, yellow seasoning tuna, and tuna salt solution. Simulation results for optimizing canned fish production are 5.7863 q/day which provides the optimum supply of canned fish. Keywords: Analytic Network Process (ANP), Fish canning, Fuzzy Inference System (FIS) Tsukamoto, New product selection, Production capacity.
