“…Gambar 6 : Uji FTIR Pencahayaan menggunakan sinar berwarna ungu dengan panjang gelombang 380-450 nm sudah sesuai dengan kecepatan laju adsorpsi yang diharapkan, dengan nilai pH akhir 4.8. Gelombang elektromagnetik yang dihasilkan pada cahaya berwarna ungu disinyalir mampu menggetarkan senyawa aromatik yang terkandung dalam karbon aktif kulit bawang merah [27]. Dimana senyawa aromatik berbentuk hexagon dengan ikatan C-H, dengan adanya pancaran gelombang elektromagnetik, elektron yang terdapat pada cincin aromatik terdelokalisasi dan menyebabkan elektron dapat bergerak bebas secara energik diseluruh struktur sehingga menimbulkan sifat layaknya konduktifitas.…”

Onion peel is one of the solid waste produced either from the onion processing industry or waste from household waste. Onion skin contains cellulose compounds that are quite high, which is 41-50% as well as aromatic compounds. It is underlying that onion skin can be used as a raw material in the manufacture of activated carbon. One of the uses of activated carbon is as an adsorbent in the conditioning of pH and TDS levels in battery water waste. The manufacture of activated carbon is carried out with 3 main stages, namely carbonization with a temperature of 400oC for 1 hour, sorting particle sizes of 10-16 mesh and 60-200 mesh, and variations of NaOH activators of 10%, 15%, and 25%. Other variations used in the study included the use of 12V/100W floodlights in the purple, yellow, and no lighting spectrum, as well as an active carbon mass of 0.5 and 1 gram. The best adsorption rate is obtained with variations in activated carbon 60-200 mesh, activated carbon mass against a solution of 1 gram, and with purple lighting with a wavelength of 380-450 nm where the initial pH 2 and final pH of 4.8 and TDS decreased by 180 Ppm where the initial TDS is 9,690 Ppm and the final TDS is 9,510 PPM and has the potential to produce hydrogen.

Waste Motor Oil (WMO) is a hazardous waste material with the potential to contaminate water, soil, and the atmosphere. The management and engineering of WMO have become imperative in modern society for both resource utilization and environmental protection. Maximizing the energy content of WMO poses a significant challenge for researchers, to solve environmentally friendly solutions. Direct combustion of WMO often results in incomplete combustion and elevated CO emissions. Therefore, this research aims to optimize the harnessing of WMO's energy potential through a furnace equipped with steam injection. The steam is generated by utilizing the heat energy produced during the WMO heating process. Our study demonstrates that steam injection in the WMO furnace is an effective method for maximizing energy content while simultaneously reducing CO emissions.

“…In this case, there is an urgent need for researchers to develop renewable green energy sources [ 2 , 3 ]. However, hydrogen energy has received more and more attention due to its clean, easy-to-obtain and low-cost advantages [ 4 ]. At present, the main hydrogen production methods mainly include thermochemistry, electrolysis, and photocatalysis [ 5 , 6 ].…”

Porous biochar materials prepared with biomass as a precursor have received widespread attention. In this work, lotus pollen (LP) was used as the carbon source, a variety of the pollen carbon photocatalyst were prepared by a two-step roasting method. A series of characterizations were carried out on the prepared samples, and it was found that the average particle size was about 40 μm. They also exhibit a typical amorphous carbon structure and a porous structure with a network-like interconnected surface. The photocatalytic hydrogen production performances of lotus pollen carbon (LP-C) and commercial carbon black (CB) were measured under the full spectrum illumination. LP-C-600 showed the best hydrogen production performance (3.5 μmol·g−1·h−1). In addition, the photoelectrochemical (PEC) measurement results confirmed that the LP-C materials show better incident photon-current efficiency (IPCE) performance than the CB materials in the neutral electrolyte. This is because the unique surface wrinkling, hierarchical porous structure, and the N, P self-doping behavior of the LP-C samples are able to improve the light utilization efficiency and the carrier separation/transfer efficiency, thereby further improving the overall hydrogen production efficiency.
