Abstract

Lingkungan pesisir dan laut merupakan hilir dari berbagai dampak pembangunan baik yang memanfaatkan sumber daya alam yang berada di darat maupun di laut. Apabila tidak dilakukan kegiatan pengendalian kerusakan lingkungan pesisir dan laut, akan terjadi suatu keadaan yang berdampak negatif pada ekosistem mangrove, padang lamun, terumbu karang, dan biota laut yang berada di wilayah tersebut serta kehidupan manusia di sekitarnya. Undang-Undang Republik Indonesia Nomor 32 Tahun 2009 tentang Perlindungan dan Pengelolaan Lingkungan Hidup mengamanatkan untuk dilakukannya perlindungan lingkungan laut dan pengendalian kerusakan ekosistem mangrove, padang lamun, dan terumbu karang. Peranan pemerintah, swasta, dan masyarakat dalam hal ini menjadi bagian terpenting yang tidak terpisahkan dalam upaya pengendalian kerusakan dan pengelolaan lingkungan pesisir dan laut. Oleh sebab itu perlu dilakukan identifikasi permasalahan lingkungan di wilayah pesisir dan laut guna mendukung kegiatan pengembangan kebijakan dan kegiatan pengendalian kerusakan lingkungan pesisir dan laut melalui peran serta masyarakat Kabupaten Gresik. Hasil identifikasi permasalahan tersebut diharapkan dapat menyediakan data kualitatif maupun kuantitatif yang dapat digunakan sebagai acuan dalam pelaksanaan kebijakan perlindungan dan pengelolaan lingkungan pesisir dan laut di Kabupaten Gresik

Abstract

Scrap tires continuously generated due to increasing motorized vehicle use. In Indonesia, tire waste generation reaches approximately 11 million tons annually. One processing method is pyrolysis, which converts tires into carbon, oil, and metals. However, the carbon, comprising 25–30% of tire conten, remains underutilized. This study aims to compare the performance of Tire-derived Activated Carbon (TAC) and Commercial Activated Carbon (CAC) in Pb(II) removal from wastewater. The carbon was activated using 98% H₂SO₄ (1:1 w/w) and heated in a fluidized bed reactor at 600, 650, and 700 °C for 1 hour. The optimal TAC was produced at 600 °C, with a specific surface area of 103.162 m²/g. FTIR analysis confirmed the presence of -OH, C=C, and C=O functional groups, and SEM revealed a porous structure. Adsorption tests at varying pH and initial Pb(II) concentrations showed optimum performance at pH 5 and 30 mg/L. The Langmuir model fitted the data well, indicating monolayer adsorption on a homogeneous surface. TAC achieved 96.32% removal efficiency in synthetis medium and a maximum adsorption capacity of 240.80 mg/g, significantly higher than CAC (62.68%, 151.366 mg/g). These results demonstrate the potential of TAC as an effective low-cost alternative adsorbent for heavy metal removal.
