In this study, the goose meat was used as raw material and the formula of composite tender agent was optimized by Response Surface Methodology. Goose breast meat were soaked with exogenous protease of plants, phosphate and Ca2+ for 3 hours at 2 °C. The influence of different composite tender agent on the water-holding capacity was examined by statistical response surface methodology (RSM). The result showed that papain 6.16 U/g, compound phosphate 0.308 % and calcium chloride 0.133 % was helpful to increase the tenderization of goose breast. The results of our study would be used to improve the tenderness of goose meat and increase economic efficiency of goose industry.

Kulit koro pedang putih dapat digunakan sebagai sumber selulosa. Salah satu alternatif untuk meningkatkan aplikasi selulosa adalah dengan memodifikasi selulosa menjadi produk turunan selulosa yaitu Hydroxypropyl Methyl Cellulose (HPMC). Tujuan dari penelitian ini adalah melakukan optimasi terhadap sintesis dan karkaterisasi HPMC dari selulosa kulit koro pedang putih. Proses optimasi didahului dengan kajian literatur untuk menentukan kisaran titik percobaan dengan variabel terikat berupa molar subtitusi (MS) dan Derajat Subtitusi (DS). Diperoleh titik percobaan dengan variasi konsentrasi NaOH (5, 22,5, dan 40%), variasi Dimetil Sulfat (DMS) (40, 80, dan 120%), dan variasi Proilen Oksida (PO) (80, 120, dan 160%). Kemudian optimasi sintesis HPMC dilakukan dengan mengunakan Box-Behnken design (BBD) lalu dianalisis menggunakan Response Surface Methodology (RSM) Berikutnya HPMC dikarakterisasi meliputi molar subtitusi (MS), Derajat Subtitusi (DS), water holding capacity (WHC), oil holding capacity (OHC), lightness, rendemen, kristalinitas dan spektra FT-IR untuk mengetahui gugus fungsi HPMC. Hasil optimasi sintesis HPMC dari selulosa kulit koro pedang putih berdasakan RSM diperoleh titik optimum pada konsentrasi NaOH 23,11%, DMS 43,4% dan PO 81,8%. dengan karakterisasi kadar air 9,04% (wb); MS 0,15; DS 1,18; WHC 2,20 g/g; OHC 2,09 g/g; lightness 90,93; rendemen 114,78% dan kristalinitas 64%. Spektra FT-IR HPMC koro pedang putih terbaca pada bilangan gelombang 2924 cm-1 (CH dan CH2 Streching), 1373 cm-1 (CH3 Bonding), 1118 cm-1 (C-O-C), 1319 cm-1 (O-H Plane Bonding) dan 848, 68 cm-1 (C-O-C pada 1,4 β glikosidic linkage) yang merupakan ciri khas dari gugus fungsional HPMC.

Filling grouting is effective to control the overlying strata movement and surface subsidence in mining and tunnel engineering.Grouting material is used in grouting reinforcement projects. In this experiment,based on the mechanical properties of grouting materials, Expert Design and response surface methodology (RSM) is used to optimize the mix proportion of grout materials. The sand-fly ash ratio ,water reducing agent addition are researched as variables, and the 3D response surface is established between the factors and the performance indicators. Microstructure explains the mechanism of factors affecting performance indicators.The results show the relationship between factors and performance can be well fitted by RSM.The order of significance on compressive strength and solidification ratio is sand-fly ash ratio>water reducing agent addition and the order of significant on viscosity is water reducing agent addition>sand-fly ash ratio.Response surface methodology accurately describes the functional relationship between the target value and the design variables.Microstructure shows hydration reaction and the secondary hydration reaction of fly ash will be carried out after cement-fly ash mixed, and the addition of fly ash is especially important for grout material properties.
