Abstract

The purpose of this study is to solve multi-criteria problems using the ε-constraint method with the help of an excel solver. The multi-criteria optimization problem is an optimization problem that has more than one objective function. A multi-criteria optimization problem can be said to be a multiple criteria decision making (MCDM) if there is more than one thing that must be considered in the model as a goal or criterion. In general, the weighting method and the ε-constraint method are the most widely used. The weighting method converts a set of options into options by multiplying each option by the inventory weight. On the other hand, the ε-constraint method only saves one of the existing goals and limits the goals with a certain number of values to get an efficient limit.

Abstract

Red ginger (Zingiber officinale var. rubrum) with a high content of phenols (e.g. gingerol, shogaol, etc.) has potential effects against throat inflammation such as cold, sore throat, tonsilitis, etc. This research aims to determine the formulation of lozenge tablets using red ginger extracts. Lozenges tablets are made from dry ginger extract using a wet granulation method prepared by various concentrations of pregelatinized cassava starch 1 % w/v (F0); 2 % w/v (F1) and 5 % w/v (F2) as a binder and HPMC 2 % w/v (F3) as a comparative binder. Red ginger extract was prepared by maceration method using 96% ethanol solvent which is then evaporated using a rotary evaporator to obtain a thick extract. Thick red ginger extract is formulated into lozenges with various formulations F0, F1, F2, and F3. Physical characteristics evaluation of lozenge tablets includes physical appearance, weight uniformity, hardness, and disintegration time. The physical appearance of the tablet is round in shape and bright yellow in color. Based on the evaluation of all the formulas made, F2 has good criteria as a red ginger extract lozenge which has a hardness of 6 kg and disintegration time of 5 minutes 4 seconds.
