Penggunaan plastik akan semakin meningkat seiring dengan bertambahnya jumlah populasi penduduk dan meningkatnya perkembangan teknologi. Meningkatnya sampah plastik menjadi masalah besar bagi kehidupan dan ekosistem, Karena plastik sulit terurai di dalam tanah dan membutuhkan waktu yang lama untuk dapat terurai. Dengan  adanya permasalahan tentang banyaknya sampah plastik yang sulit di uraikan  maka dapat dilakukan dengan metode pirolisis, metode pirolisis adalah proses pemanasan sampah plastik dengan menggunakan sedikit oksigen atau tanpa oksigen di dalamnya. Untuk memperbaiki minyak hasil pirolisis maka ditambahkan katalis sebagai katalisator sehingga memperoleh hasil minyak pirolisis lebih baik. Tujuan penelitian ini adalah untuk mengetahui perbedaan minyak PET (polyethylene terephthalate) dan PP (polypropylene), untuk membandingkan hasil pirolisis dari penggunaan katalis dan tidak menggunakan katalis terhadap viskositas minyak yang dihasilkan,  serta pengaruh waktu pemanasan terhadap hasil volume minyak pirolisis. Dari penelitian yang dilakukan didapatkan hasil minyak terbanyak dengan bahan plastik PP dengan katalis 33 ml atau 8,46 %,  PET katalis 23 ml atau 8,943 % dan minyak PP tanpa katalis 76  ml atau 19,26 %, PET tanpa katalis 65 ml atau 17,23%. The use of plastic will increase along with the increasing population and increasing technological development. Increased plastic waste is a big problem for life and ecosystems, because plastic is difficult to decompose in the soil and requires a long time to be decomposed. With the problem of the amount of plastic waste that is difficult to describe, it can be done with the pyrolysis method, the pyrolysis method is the process of heating plastic waste using little or no oxygen in it. To improve the pyrolysis oil, the catalyst is added as a catalyst to obtain better pyrolysis oil results. The purpose of this study was to determine the differences in PET (polyethylene terephthalate) and PP (polypropylene) oils, to compare the results of pyrolysis from the use of catalysts and not use catalysts to the viscosity of the oil produced, as well as the effect of heating time on the results of the pyrolysis oil volume. The results of the research showed that most PP plastic catalyst oils were 33 ml or 8.46%, catalyst PET 23 ml or 8.943% and PP oil without catalyst 76 ml or 19.26%, PET without catalyst 65 ml or 17.23%.

This study aims to evaluate the performance of gasoline engines using pure fuel (pertalite) with plastic pyrolysis oil (PPO) fuel from low-density polyethylene (LDPE) plastic waste. The test was carried out on a four stroke, single cylinder test bed machine. The research begins with the manufacture of fuel from low-density polyethylene (LDPE) plastic waste using the pyrolysis method. The performance parameters evaluated are torque, power and specific fuel consumption (BSFC). The results of the test show that the engine performance using LDPE type plastic waste fuel is relatively lower than pertalite. However, the consumption of LDPE fuel is lower than pertalite.

This research aims to study the effect of temperature, collecting time, and condensers on properties of pyrolysis oil. The research was done be analyzing viscosity, density, proportion of pyrolysis products and performance of each condenser towers for the pyrolysis of high-density polyethylene (HDPE) and polyethylene terephthalate (PET) in the mobile pyrolysis plant. Results showed that the main product of HDPE resin was liquid, and the main product of PET resin was solid. Since the pyrolysis of PET results in mostly solid which blocked up the pipe, the analysis of pyrolysis oil would be from the use of HDPE as a raw material. The pyrolysis of HDPE resin in the amount of 100 kg at 400, 425, and 450°C produced the amount of oil 22.5, 27, and 40.5 L, respectively. The study found that 450°C was the temperature that gives the highest amount of pyrolysis oil in the experiment. The viscosity was in the range of 3.287–4.850 cSt. The density was in the range of 0.668–0.740 kg/L. The viscosity and density were increased according to three factors: high pyrolysis temperature, number of condensers and longer sampling time. From the distillation at temperatures below 65, 65–170, 170–250, and above 250°C, all refined products in each temperature range had the carbon number according to their boiling points. The distillation of pyrolysis oil in this experiment provided high amount of kerosene, followed by gasoline and diesel.

Sintering of zirconia usually takes a long time. In recent years, new products with extremely short sintering time have been released. Therefore, it is useful to study in detail the effect of sintering temperature and time on translucency of zirconia. The prepared discs were sintered under four conditions; 30 minutes, 40 minutes, 50 minutes and 60 minutes as firing temperature rising time up to 1500°C. Samples were measured with a spectrophotometer and translucency parameter (TP), opalescence parameter (OP) and contrast ratio (CR) were calculated. In this study, there were no statistically significant differences between TP, OP and CR due to the differences in heating rates. There is a possibility that a heating time up to the sintering temperature does not affect translucency of zirconia.
