Carbon Dots (CDs) were synthesized using laser ablation by focusing the laser beam on carbon (Tea) material in colloid (CH3) for 3 hours. UV-Vis spectroscopic and fluorometric characterization showed absorption of the wavelength peaks caused by the control treatment and after laser ablation and coating using Poly Ethylene Glycol (PEG400). The excitation and emission energies are formulations of CDs absorbance wavelength and fluorescence intensity. The absorbance coefficient is obtained based on the absorbance value of the cuvette thickness. The transmittance value (T) is obtained based on the absorption coefficient multiplied by 100%. CD fluorescence wavelength based on control parameters was 489 nm. After laser ablation was 496 nm, and after coating was 511 nm. CDs morphology and size characteristics are 4 nm to 10 nm based on TEM measurements. Fluorescence analysis for bioimaging applications on the luminescence intensity value of internalized blue CDs in zebrafish eye organs. The average intensity of CDs in the eye organs, gill, intestinal, dorsal, and tail injection points was 88.15 %, 91.58 %, 92.76 %, and 0.00 %.

This review focus on the effect of doping rare earth metals, transition metals, noble metals, poor metals, and non-metals on ZnO nanoparticles. ZnO is a semiconductor material with an average wide energy band gap of 3.2 eV. The doping is used to improve the properties of ZnO which strongly depend on their application. The concentration of doping, the type of doping and the process using sol-gel, hydrothermal and precipitation methods are affected in modifying the ZnO lattice parameters. The transition metal widely used for photocatalysts and sensors. The doped application of ZnO nanoparticles as a semiconductor material has proven advantageous in enabling various photocatalytic, glucose biosensors, VOC detection sensors, antibacterial, biomedical, and optoelectronic spintronic, LED, NLO, and silicon solar cells. This review provided information for scientist in choosing the synthesizing methods of ZnO with desired properties and application in future.

Bio-briquettes of organic waste can be used as alternative energy to solve the waste problem. This study aimed to determine the quality of bio-briquettes made of LDPE, coconut husk, and coconut shell with tapioca adhesive. The coconut husk and shell were carbonized at 300 °C for 60 minutes. Charcoal that has been ground and sieved with 40 mesh is mixed with tapioca flour adhesive, and pieces of LDPE are added. Then, the sample is pressed with a cylindrical mold with a matrix strength of 5 tons. Bio-briquettes were dried in an oven at 80 °C for 12 hours. The quality of the briquette was evaluated through proximate analysis, including the calorific value, moisture content, ash content, volatile matter content, and fixed carbon content. The calorific value of all samples complied with the regulation of the Ministry of Energy and Mineral Resources (ESDM) No. 047 of 2006, which is above 4400 cal/g. The maximum moisture content is 15%, which fulfills SNI 06–3730-1995 standards, and the ESDM regulation, especially for the composition of 40% shell: 40% coconut: LDPE 20%. The ash content, volatile matter content, and fixed carbon content of all samples did not comply with SNI briquette standards and ESDM regulations.

study aims to see the effect of adding TiO2 on activated carbon as a material for reducing CO and HC gas emissions. Activated carbon (AC) was synthesized from orange peel waste at a carbonization temperature of 600 with a 10% (w/v) ZnCl2 activator. Composite AC/TiO2 was prepared by a simple mixing method. This process obtained TiO2-modified activated carbon material with variations in TiO2 concentrations of 0%, 10%, 15%, 20%, and 25%. Scanning Electron Microscope (SEM) was performed to obtain information on the AC/TiO2 surface morphology. In the application as a CO and HC gas emission reduction material, the results of mixing AC/TiO2 are mixed with a 10% (w/v) solution of Polyvinyl Alcohol (PVA) as an adhesive and molded in the shape of a filter with two variations hole sizes with a diameter of 1 cm and 0.3 cm. Composite filter performance tests were carried out using a gas analyzer. The best result for reducing gas emissions occurred at a concentration of TiO2 15% with reduction power to reduce CO gas emission up to 53.79% and HC gas emission up to 55.57%.
