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.

The first stage of this research was to make polystyrene grafted with maleic anhydride for making the couping agent with other filling compound. In the second stage, the polystyrene matrix grafted with maleic anhydride was combined with filler material derived from palm oil mill waste using the dry mixing method with an internal mixer. Among several variables tested, the optimum composition of the polymer composite was found to be Polystyrene grafted with maleic anhydride: sludge: boiler ash in a ratio of 60:25:15. This composition exhibited a Young's modulus of 856.752 MPa, a tensile strength of 6.057 MPa, and an elongation at break of 0.775%. Differential Scanning Calorimetry (DSC) testing revealed a glass transition temperature of 403.22°C, a crystallization temperature of 426.39°C, and a cross-linking indication temperature of 478.64°C. Scanning Electron Microscopy (SEM) tests showed an even distribution of the material. Fourier-transform infrared (FT-IR) spectroscopy indicated a decrease in absorption peaks at 3024.94 cm⁻¹ and 3025.15 cm⁻¹, while the polystyrene characteristics at the wave number 1600.57 cm⁻¹ appeared sharper. The sound absorption test results met the ISO 11654:1997 standard for the rating level of sound absorption coefficient in materials, achieving Class D and C sound absorption with an αₙₓ value ranging from 0.328 to 0.793.

Soil stabilizer polymer hasil campuran lateks polyester tak jenuh Yukalac 157 BQTN-EX dengan lateks pekat karet alam (LPKA), disebut soil stabilizer termoset (SSTS). Campuran ini homogen pada perbandingan 90/10 dan stabil hingga hari ke 28 penyimpanan, dapat digunakan sebagai perekat tanah pasir untuk meningkatkan sifat kekuatannya. Melalui berinteraksi gugus polar pada polester dengan partikel tanah pasir diprediksi dapat membentuk komposit yang memiliki sifat mekanis yang tangguh sebagai material jalan. Hasil uji mekanis komposit tanah yang distabilkan dengan SSTS meningkat hingga penambahan SSTS 35%. Kuat tekan meningkat hingga penambahan SSTS 25% dan menurun pada penambahan lebih tinggi . Daya serap air menurun dengan peningkatan jumlah SSTS. Hasil uji termal terdapat pergeseran puncak dari polyester, SSTS dan komposit campuran SSTS dengan tanah pasir.
