Abstract

Peat water is characterized by high acidity, turbidity, and poor sensory qualities, which limit its usability. This study evaluated the effectiveness of thermally activated coffee waste adsorbent (CWA) for peat water treatment. CWA was prepared by heating coffee waste at 250°C, followed by washing and drying at 60°C. Batch adsorption experiments were conducted using 1–3 g of CWA in 200 mL of peat water at 30°C, stirred at 150 rpm for 30 minutes. The results revealed significant improvements in water quality: pH increased from 3.85 to 4.62; turbidity was reduced by 99.37% (from 75 to 0.47 NTU); conductivity decreased by 30.7% (from 424 to 294 ?S/cm); and total dissolved solids (TDS) dropped by 93.3% (from 208 to 14 ppm). The Langmuir isotherm model (R² = 0.7297) provided a better fit than the Freundlich model (R² = 0.5845), indicating monolayer adsorption behavior with a maximum capacity of 0.1634 mg/g and a favorable separation factor (RL = 0.0057). Sensory evaluation confirmed enhanced color and odor. These findings support the use of CWA as a sustainable and low-cost adsorbent for improving peat water quality.

Abstract

Ketersediaan air bersih merupakan masalah yang perlu dipikirkan, terlebih penyediaan air bersih di tingkat komunitas. Desa Pematang Jering yang terletak di Kabupaten Muara Jambi, Provinsi Jambi merupakan desa yang terletak berdekatan dengan sungai serta kebun warga. Berdasarkan curah hujan tahunan beserta lokasi desa, bencana banjir merupakan tantangan besar. Pestisida yang digunakan pada tanaman sawit dapat terbawa air banjir ke pemukiman warga dan menjadi kontaminasi di sumur warga yang digunakan untuk berbagai keperluan sehari-hari. Penghilangan kontaminasi dari air merupakan hal yang perlu dilakukan untuk meningkatkan kualitas hidup masyarakat. Studi kelayakan dilakukan untuk mengetahui apakah teknologi penjernih air perlu dibangun dan estimasi biaya rancangan penjernih air telah dilakukan. Berdasarkan evaluasi dan survei lapangan, teknologi penjernih air layak didirikan. Teknologi penjernih air dibangun untuk meningkatkan kualitas air sumur warga dengan mengurangi kontaminasi kimia maupun fisik dengan filter sederhana maupun modern. Biaya pembangunan teknologi penjernih air telah dihitung berdasarkan rancangan. Teknologi penjernih air sederhana memiliki biaya pembangunan sebesar Rp3,036,000. Teknologi penjernih air modern memiliki biaya pembangunan sebesar Rp3,773,000. Perbedaan biaya ini terletak di filter air yang digunakan yakni pasir, kerikil, dan ijuk untuk filter air sederhana serta pasir silika dan karbon aktif untuk filter air modern.

Abstract

Polypropylene (PP) membranes exhibit advantageous characteristics for filtration processes, including chemical resistance, thermal stability, hydrophobicity, low cost, and mechanical durability, making them well-suited for long-term applications in water treatment, particularly for removing organic compounds. This study aims to evaluate the performance of hollow fiber PP membranes in the ultrafiltration of humic acid solutions, serving as a model organic contaminant. The experimental setup involved filtering a 15 mg/L humic acid solution in demineralized water at 1 bar for 120 minutes. Performance evaluation focused on three parameters: pure water flux, humic acid permeate flux, and rejection efficiency. The initial pure water flux reached 72 L/m²·h, decreasing to approximately 57 L/m²·h within the first 20 minutes, indicating membrane compaction. The humic acid permeate flux declined from 42 to 33 L/m²·h, attributed to fouling caused by physical and chemical interactions between humic acid and the PP membrane surface. Rejection efficiency dropped from an initial 90% to 75% by the end of the process. The observed performance degradation was linked to adsorption, pore blocking, and concentration polarization. Despite their structural advantages, PP membranes are prone to organic fouling; therefore, surface modification and feedwater pretreatment are recommended to optimize long-term performance.
