Abstract

A research to model particulate emission was conducted in the plywood industry in Kendalrejo, Talun, Blitar Regency, East Java at an altitude of 273 masl. The industry already has an environmental pollution control unit, with an outlet through a chimney emitting an average emission of 0.14 g/s. The model simulation was carried out using AERMOD View software with data on wind direction and speed, solar radiation, temperature, clouds, and air pressure. The results show that the presence of the wood industry in Talun, Blitar Regency will have an impact on particulate emissions to areas in the east, southeast, west, and south, as the dominant wind direction. Dispersion modeling of particulate pollution with current conditions has resulted in dispersion with concentrations below the allowable limit in PP 22 of 2021. Modeling with several scenarios shows that the dispersion pattern can be maximized by increasing the chimney emission rate to 18 m/s, to minimize turbulence around the chimney and accelerate the reduction of particulate concentrations. Increasing the height of the chimney or increasing the diameter of the chimney will also affect the decrease in concentration in all directions so it becomes a recommendation that should be considered by the industry.

Abstract

Hospital hazardous waste (B3) management is crucial to avoid negative impacts on health and the environment. This community engagement aimed to improve B3 waste handling capacity in a regional hospital in East Java. Activities included site observation, technical discussions, SOP development, labeling training, and digital reporting via the Festronik system. Observations revealed issues in waste labeling, characterization, and logbook documentation. Interventions successfully improved labeling according to waste properties, developed technical SOPs, and fulfilled storage requirements based on Government Regulation No. 22 of 2021 Article 419 paragraph (4). Enhancements such as emergency response tools and updated signage further supported safe and compliant waste management. This program is expected to strengthen sustainable B3 waste governance in the healthcare sector.

Abstract

Incomplete combustion of fossil fuels resulting from motor vehicle emissions releases hazardous pollutants such as carbon monoxide (CO) and hydrocarbons (HC). The high levels of these gases in emissions pose a significant threat to public health, creating an urgent need to develop and implement highly efficient processing or reduction technologies to ensure exhaust gas emission parameters remain within safe limits. This study demonstrates that activated carbon derived from siwalan (lontar) shell, specifically after activation with 25% Na2CO3 is highly effective in lowering exhaust gas emission levels, with the greatest reduction achieved using the largest adsorbent mass of 100 grams. The effectiveness of this adsorption is further supported by the statistical results of the Two-Way ANOVA model, which confirmed a significant influence of both adsorbent mass and adsorption process time. Consequently, the use of activated carbon from siwalan shell proves to be an effective and efficient solution for mitigating motor vehicle gas pollution. It holds significant potential for use as an emission reduction tool, particularly for older motor vehicles that lack existing emission control devices, and serves as a vital effort to comply with government regulations aimed at maintaining stable ambient air quality.

Abstract

Polyvinylidene fluoride (PVDF)-based ultrafiltration membranes are widely used because they can remove suspended and dissolved contaminants from water. However, fouling remains a major challenge, causing flux reduction and shortening the lifespan of the membrane. This study evaluated the performance of PVDF membranes when filtering Jagir River water, and assessed the effectiveness of stepwise washing with citric acid (C₆H₈O₇) and hydrogen peroxide (H₂O₂). Experiments were conducted at operating pressures of 1, 1.5 and 2 bar. Membrane flux was measured under four operating conditions: initial flux using distilled water (Jw1); river water flux before washing; flux using distilled water after washing (Jw2); and river water flux after washing. The results showed that Jw1 increased with increasing pressure, reaching a maximum value at 2 bar. However, river water filtration caused a significant decrease in flux due to fouling. Stepwise chemical washing partially recovered the flux, as indicated by the increases in Jw₂ and river water flux after washing. However, full recovery was limited by irreversible fouling. The highest Flux Recovery Ratio (FRR) value was obtained at 2 bar with a 6 wt% washing solution, indicating that the combination of high pressure and chemical treatment provides optimal performance recovery. Overall, the PVDF membrane can be effectively regenerated using citric acid and hydrogen peroxide; however, organic and inorganic mixed fouling limits total flux recovery.

Abstract

This study aims to evaluate the effectiveness of activated carbon produced from banana peels and cassava peels in reducing iron (Fe) levels in the water of the Porong River, Sidoarjo. Activated carbon was produced through a carbonization process and chemical activation using a 15% H?PO? solution. Tests were conducted with varying column heights (20, 40, 60, 80 cm) and sampling times (30–150 minutes). The results showed that cassava peel activated carbon was more effective in removing Fe with a maximum removal percentage of 83.13% at a column height of 80 cm and a sampling time of 150 minutes, while banana peels reached 72.22%. This study proves the potential of organic waste as an environmentally friendly adsorbent for the remediation of water contaminated with heavy metals.

Abstract

Industri batik menghasilkan air limbah yang di dalamnya terkandung logam berat kromium heksavalen Cr(VI) dengan sifat toksik, karsinogenik, dan berbahaya bagi lingkungan perairan. Salah satu metode yang berpotensi efektif dan ramah lingkungan untuk menurunkan kadar Cr(VI) adalah fotokatalisis. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan komposit ZnO–karbon aktif dan massa katalis terhadap kinerja fotokatalisis dengan iradiasi sinar tampak dalam menurunkan kadar Cr(VI) pada air limbah batik. Variasi yang digunakan meliputi massa katalis sebesar 30 gram, 45 gram, dan 60 gram. Hasil penelitian menunjukkan bahwa penggunaan komposit ZnO-karbon aktif mampu meningkatkan efisiensi penurunan Cr(VI) dibandingkan ZnO tanpa modifikasi. Kombinasi kondisi optimal diperoleh pada penggunaan komposit ZnO - karbon aktif dengan massa terbesar dan waktu kontak terlama dengan efisiensi penyisihan sebesar 39%.
