Abstract

The rapid growth of fisheries in Sorong city has led to severe marine pollution, especially elevated Cu II concentrations that exceed water‑quality standards and threaten both ecosystems and human health. This study aimed to develop an eco‑friendly adsorbent from agricultural waste, namely citric‑acid‑activated palm‑shell powder, for the removal of Cu II from fishing‑industry effluents. The palm‑shell powder was activated by immersion in 0.1 M citric acid for 24 h, which introduced carboxyl groups, eliminated impurities, and increased porosity and surface functionality, thereby enhancing Cu II sorption capacity. A full‑factorial experimental design was employed, testing three independent variables (adsorbent mass, solution pH, and temperature) each in triplicate, with a fixed contact time of 120 min, sample volume of 50 mL, and initial adsorbent pH 6. Optimal conditions were identified as 50 mg adsorbent (capacity = 8.354 mg L⁻¹, removal efficiency = 54.14 %), pH 9 (capacity = 10.69 mg L⁻¹, efficiency = 69.28 %), and 60 °C (capacity = 7.49 mg L⁻¹, efficiency = 48.56 %). The citric‑acid‑activated palm‑shell adsorbent demonstrated significant Cu II reduction in fishing‑effluent water and presents a low‑cost, locally available, and sustainable solution for the treatment of fisheries waste streams.

Abstract

Matoa fruit is abundant in Papua and has not been optimally utilised. Matoa fruit consists of ash approximately 3.74%. The high ash and silica content make it highly suitable as a raw material for zeolite production. Zeolite can be used as a zeolite material to adsorb heavy metal Cu(II). Heavy metal pollution continues to increase with industrial growth. Heavy metals can harm human health. Innovation must continue addressing heavy metal pollution, such as Cu(II), to produce more efficient, cost-effective, and environmentally friendly technologies. This study aims to determine the ability of matoa fruit zeolite to adsorb heavy metal Cu(II). The characterization of zeolite was done using XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscope). The synthesis process involved preparing sodium aluminate and sodium silicate solutions, followed by controlled crystallisation at 105°C for 24 hours. The zeolites were tested for adsorption with the independent variable being zeolite mass, while the dependent variables were contact time of 48 hours and stirring time of 4 hours. SEM analysis confirmed the cubic morphological characteristics of matoa fruit zeolite, classifying the product as matoa fruit zeolite. The main findings of the study showed that matoa fruit zeolite can reduce Cu metal levels in sewage-polluted water with 88.85% adsorption at 0.5 g in 50 ml of test solution.

Abstract

The purpose of this Community Service activity is to provide clean water facilities based on science and technology at Masjid Hijau. This concept aims for environmental preservation, such as waste management as an effort to address climate change, as well as clean water management and education for teenagers and children, raising public awareness about the importance of waste management as an effort to tackle climate change, and 3) making mosques centers for community development. In its implementation, it is divided into two parts: workshops and green mosque practices. The hope is that after this service ends, the Babul Jannah Mosque in the Kokoda complex will truly implement the eco-mosque concept in mentoring the youth, making it a model for other mosques, especially those in Sorong City. For that reason, the community service program aims to provide clean water facilities and infrastructure, Green Mosque IPTEK training in well water filtration using the absorption method, training on the procedures, maintenance, and upkeep of clean filter equipment, character-building training for the Green Mosque, which includes environmental love, community IPTEK training on composting to produce fertilizer, equipping waste disposal facilities based on organic, inorganic, and hazardous waste categories, Trainer of Trainer training for mosque administrators to guide the youth and children around the mosque, and capacity-building for the mosque's BKM team. The training was with 18 participants out of 23 registered. The target of this activity is to gradually produce posters, HAKI, scientific journals, activity videos, and partner skill enhancement.
