In this work, a novel multipurpose Faujasite (FAU) zeolite composite membrane was fabricated by in‐situ hydrothermal method to separate different solute molecules such as vanillic acid, phenol, and brilliant green from the aqueous solution. The coal fly ash based ceramic substrate was synthesized and used as substrate for preparing the zeolite composite membrane. The X‐ray diffraction (XRD) pattern confirmed the crystalline nature of membranes and the presence of Quartz and hematite in the composite membrane. The presence of Si‐O and Al‐O in zeolite coated composite membrane was confirmed by Fourier Transform infrared spectroscopy (FTIR) analysis. Scanning electron microscope (SEM) analysis showed the porous structure and 8.34 μm thickness of zeolite coating on membrane. The isoelectric point of composite membrane was observed at pH 2.07 through zeta potential analysis. Brunauer‐Emmett‐Teller (BET) surface area, average pore volume and pore diameter of zeolite composite membrane were estimated as 6.406 m2/gm, 0.0070 cm3/gm, and 4.371 nm, respectively. The hydraulic pore radius and porosity of composite membranes were 27.7 nm and 20.1%. The maximum separation efficiency of FAU zeolite composite membrane towards vanillic acid, phenol and brilliant green was estimated as 78.67%, 89.13%, and 94.28%, respectively, for 200 mg/L feed concentration at 276 kPa applied pressure. The results obtained in this study reveals that the multipurpose FAU zeolite composite membrane fabricated in this study can be effectively used for separation of various solutes molecules present in the wastewater.

The decline in the quality of waste management has generally started to occur since the prolonged economic crisis in Indonesia. Plastic waste includes inorganic waste, which is currently widely used by industry and households. Therefore, it is necessary to have an alternative recycling process, like converting plastic waste into liquid fuel. The research objective is to utilize LDPE plastic waste (Low-Density Polyethylene) and PP (Polypropylene)in liquid fuelutilizing pyrolysisto determine the effect of using a zeolite catalyst by comparing the results of the pyrolysis process. The investigation took place at the Wonosari landfill in Singkawang, where parameters such as density, viscosity, and color were examined. The pyrolysis results underwent consistency testing through the Mann-Whitney test. According to the study findings, the average physical parameter values for viscosity and density of LDPE pyrolysis liquid fuel were 0.302 cP, LDPE+catalyst was 0.114 cP, with densities of 767 kg/m3 and 737 kg/m3. For PP, the average viscosity was 2.812 cP, and PP+catalyst was 0.248 cP, with densities of 774 kg/m3 and 735 kg/m3. Samples of PP and LDPE with catalysts exhibited lower density values compared to those without catalysts.

Pemeraman dapat meningkatkan laju nukleasi serta mengurangi periode induksi dan waktu kristalisasi zeolite. Sehingga, pemeraman memiliki peran penting pada proses sintesis zeolite Y. Sintesis zeolite Y dapat dilakukan dari bahan silika yang diekstrak dari lumpur Lapindo. Sintesis dilakukan dengan dan tanpa pemeraman dengan variasu suhu kristalisasi 60, 80 dan 100 oC. Hasil menunjukkan sintesis zeolite Y tanpa waktu pemeraman menghasilkan struktur berfasa amorf dengan suhu kristalisasi tidak mempengaruhi produk hasil reaksi. Sedangkan pemberian waktu pemeraman pada suhu ruang selama 24 jam sebelum kristalisasi dapat meningkatkan kristalinitas dari zeolit Y. Suhu kristalisasi juga mempengaruhi pembentukan zeolit Y, dimana kristalisasi pada suhu 100 oC menghasilkan lebih banyak produk zeolit Y daripada suhu kristalisasi 80 dan 60 oC.
