Statistical multivariate methods like Box-Behnken, face central composite and full factorial designs (BBD, FCCD and FFD, respectively) in combination with the response surface methodology (RSM) were compared when applied in modeling and optimization of th... see more

This study aims to find the optimum conditions for the adsorption of Cr (VI) ion to the eugenol-silica gel composite as an adsorbent and to determine the adsorption parameters using the Langmuir and Freundlich isotherm model. The three optimization parame... see more

2-Ethylhexyl salicylate, an ultraviolet filter, is widely used to protect skin against sunlight-induced harmful effects in the cosmetic industry. In this study, the green synthesis of 2-ethylhexyl salicylate using immobilized lipase through a solvent-free... see more

Beluntas (Pluchea Indica L.) yang biasa digunakan sebagai astringent dan antipiretik memiliki potensi yang tinggi sebagai bahan baku produksi minyak atsiri. Tujuan dari penelitian ini adalah untuk mengoptimalkan solvent-free microwave extraction (SFME) da... see more

Pengecatan adalah proses pelapisan yang diterapkan pada permukaan suatu benda. Tujuan dari pengecatan ada dua, yaitu protektif dan dekoratif. Dari segi protektif cat dapat dinilai dari ketebalan dan jika  dari  dekoratif  cat  dapat &n... see more

Resorcinol and 4-n-butyl resorcinol have been used to improve skin health. However, these two compounds were unstable due to the oxidation process. Lipid nanoparticle formulation strategies were reported as the solution to overcome the stability problem f... see more

For the first time quantitative effects of liquefied gas extraction temperature, the correlation of the extractant volume and the raw material mass, humidity and the average size of the raw material particles have been analyzed in the lipophilic complex (... see more

In this study, the influence of supercritical carbon dioxide parameter on the antioxidant activity on Swietenia mahagoni seed extract was investigated. Response surface methodology was employed, using Box-Behnken statistical design to evaluate the effects... see more

In an earlier article, the central composite design was applied to the determination of geometrical features of casts in a two-phase transformation process to produce the wheel covers of automobiles whereby the A356 alloy is reinforced with organic substa... see more
