Piroxicam solubility in water is very small this cause problem in the process of absorption so that it’s required an optimal formula to establish the physical properties of tablet quality for piroxicam tablets. The purpose of this research was creating formulas with the optimal combination of excipients lactose, Avicel pH 101, and piroxicam amprotab to obtain tablets with good physical properties and disolution. Seven piroxicam tablet formulas were made with a combination of lactose, avicel PH-101, and Amprotab on 2 batches. Method for making tablets piroxicam was established by direct compression. Tests included were the physical properties of piroxicam tablets tablets weight uniformity, uniformity of size, hardness, brittleness, disintegration test, as well as dissolution test, and content uniformity. Based on the simplex lattice design method, lactose is a dominant factor to improved the uniformity of tablet’s concentartions. Interaction of two components avicel PH-101 and amprotab is a dominant factor to reduced vulnerability. Interaction of three components lactose, avicel PH-101 and amprotab is a dominant factor to lowered the value coefisien variation of weight uniformity, increased hardness, decreased the disintegration, and improved dissolution of tablets. Selection of the optimum formula was determined by the method of simplex lattice design through diagrams superimposed contour plots and contour plots for obtaining the optimal proportions of each ingredient as follows: lactose (85,154–100%), avicel PH-101 (0–12,437%), and amprotab (0–5,425%).

Ashitaba is known to have antioxidant activity and gram-positive antibacterial activity that causes body odor. This is the potential activity for an active substance to be developed as deodorant. The appropriate formula is needed, so it is necessary to optimize the formula using the right method. This study aimed was to determine the application of the simplex lattice design method on the optimization of a deodorant roll-on formula of ashitaba extract. Ashitaba was extracted by the maceration method. The formula optimization design was determined using the simplex lattice design method by Design Expert®7.5.1. The components for optimization were the concentration of carbopol and concentration of TEA, and the optimization parameters were the spreadability test, sticky power, and pH test. The optimum formula of deodorant consists of 0.45% carbopol and 2.05% TEA. The responses of optimum formula obtained spreadability test 6.32 ± 0.33 cm, sticky power 44.67 ± 3.94 seconds, and pH 7.73 ± 0.17. These results meet the criteria for good preparation but need further testing related to the effectiveness of the preparation and the level of acceptance of the preparation by the user.

Bengkuang (Pachyrrhizus erosus) contains daidzein which is pro-estrogenic compound, suppressing bone restoration by directing mechanism in bone estrogen receptor. Bengkuang can be developed into a useful source of phytoestrogens as a supplement in menopausal women. This study aims to determine the stability and influence of Avicel® PH 101 and crospovidone on granular flow properties and physical properties of Bengkuang tuber extract. Bengkuang tuber extracts were made into tablet preparations by wet granulation method. Variation of crospovidone composition was between 2-5%, while Avicel® PH 101 was between 38.86 to 41.86%. The tablet formulation is optimized using the Simplex Lattice Design method. The results show that the addition of Avicel® PH 101 can improve the index of determination, water absorption, moisture content, hardness, time of disintegration, and friability of the tablet, as well as crospovidone addition. Avicel® PH 101 and crospovidone interactions increase water content, decrease hardness, and tablet friability. The optimum tablet formula consists of composition of 293 mg of Avicel® PH 101 and 14 mg of crospovidone per tablet. Testing of optimum formula results with SLD method did not differ significantly to the response of the compression index, hardness and friability of the tablet. The tablet was stable at room temperature (30ºC ± 2 ºC) for four weeks.
