Analisis Kinerja Campuran Aspal Beton (AC–BC) Menggunakan Liquid Asbuton Dengan Penambahan Serpih Sampah HDPE (High Density Polyethylene)

The use of asphalt (Liquid asbuton) as a road pavement material can be an economical and efficient choice for road construction and maintenance because, in addition to being cheaper and having better work abilities compared to other types of buton asphalt, a new step is carried out by using Asbuton liquid in a hot mix. One of the materials used is high-density polyethylene (HDPE) plastic waste. The ideal plastic prohibition needs to be balanced with waste management and financial incentives to change the habits of consumers and industry players. This research was conducted to determine the effect of using HDPE type plastic as an addition to the Asphalt Layer mixture Concrete (Laston) in terms of Marshall characteristics by using liquid asbuton and the level of plastic addition used was 2%, 4%, and 6% The results achieved were the addition of plastic waste flakes into the asphalt concrete mixture AC-BC can save asphalt 6% to the weight of asphalt The characteristics of the AC-BC mixture can be explained that with the addition of plastic waste flakes, stability will rise, flow decreases, Marshal Quotien (MQ) increases, VIM decreases, VMA decreases, VFB increases with increasing levels of effective asphalt, remaining marshall stability can be reached above 90%, and the cavity in the cam Puran at the refusal density can be achieved in the range greater than 2%.

Investigation of the Compressibility and Compactibility of Titanate Nanotube-API Composites

The present work aims to reveal the pharma-industrial benefits of the use of hydrothermally synthesised titanate nanotube (TNT) carriers in the manufacturing of nano-sized active pharmaceutical ingredients (APIs). Based on this purpose, the compressibility and compactibility of various APIs (diltiazem hydrochloride, diclofenac sodium, atenolol and hydrochlorothiazide) and their 1:1 composites formed with TNTs were investigated in a comparative study, using a Lloyd 6000R uniaxial press instrumented with a force gauge and a linear variable differential transformer extensometer. The tablet compression was performed without the use of any excipients, thus providing the precise energetic characterisation of the materials’ behaviour under pressure. In addition to the powder functionality test, the post-compressional properties of the tablets were also determined and evaluated. The results of the energetic analysis demonstrated that the use of TNTs as drug carriers is beneficial in every step of the tabletting process: besides providing better flowability and more favourable particle rearrangement, it highly decreases the elastic recovery of the APIs and results in ideal plastic deformation. Moreover, the post-compressional properties of the TNT–API composites were found to be exceptional (e.g., great tablet hardness and tensile strength), affirming the above results and proving the potential in the use of TNT carriers for drug manufacturing.
