The mixed surfactant pairs, i.e., NaLS+Brij-35 and NaLS+Tween-80, with photosensitizer methylene blue and reductant D-xylose have been used for PG cells. The resulting photoelectrochemical process in photogalvanics leads to energy conversion for sustainable development in the field of solar energy. The electrical outcomes, i.e., V_OC, SPP, SPC, SP, and SCE, were studied for a sunlight-induced PG cell for photocatalytic conversion.

Consequently, researchers are focusing on the development of efficient treatment methods for post-tanning effluents with the target of removing chromium to alleviate this pollution problem. In this regard, electrocoagulation has emerged as a leading technology for chromium removal from tannery wastewater. In this study, a continuous electrocoagulation column was applied for the removal of chromium ions from tannery wastewater collected from local industry. The effect of current density, pH, and effluent chromium concentration were studied for the removal of chromium ions. The results showed that a maximum chromium removal (99.94 %) was achieved within one hour in batch mode at current density, pH, and effluent concentration of 10 mA/cm², 6.5, and 500 mg/L, respectively. The continuous electrocoagulation system was used to evaluate the process dynamics and steady-state stability of the reactor system by introducing step changes in operating conditions (flow rate, pH, current density, and concentration).

Through a systematic optimization process utilizing Response Surface Methodology (RSM), the effects of solvent type, PS concentration, and titanium dioxide (TiO₂) loading on membrane performance were explored. The fabricated PS polymeric membranes were evaluated for their effectiveness in humic acid removal using a dead-end membrane filtration system. The optimal PS polymeric membrane formula, achieved at PS concentration of 16.31 wt% and TiO₂ concentration of 0.10 g/L using NMP as the solvent, exhibited a permeate flux of 166.55 L/m² h and HA rejected of 84 %. The study also demonstrates the suitability of RSM as a statistical tool for membrane formulation optimization, with low percentage errors (5.04 % for permeate flux and 0.69 % for HA rejection). Furthermore, fouling mechanism analysis utilizing the Hermia’s model confirmed the prevalence of cake filtration in the optimized PS polymeric membrane filtration.

Java Island has the highest population and is more urbanized than other islands in Indonesia. From January 2001 to January 2020, LST daytime data were downloaded from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) Land Products Global Subsetting and Visualization Tool.

The appropriate distance between sub-regions was also observed, with 105 pixels and 52.5 pixels producing two and six super-regions, respectively. It was found that seasonal patterns could be represented with pixel distances of 105 and 52.5, using eight knots of cubic splines. From 2001–2020, the lowest LST was recorded in January, while the highest was in September. The highest average daily LST, 38.32 °C, was found in Cikande, Serang, and Banten, likely due to industrial activity. This study also analyzed LST fluctuations using seven knots of the cubic spline. It was found that the average daily LST decreased by −0.113 °C per decade in Java and Bali. The western super-regions of Java showed significant LST increases, while the eastern super-regions showed slight decreases. For the 52.5-pixel distance, there was no substantial variation in average LST, though Jakarta and Banten showed significant increases. The 105-pixel distance is useful for examining LST variations on small islands like Java, while the 52.5-pixel distance can detect deeper variations in smaller super-regions.
