Abstract

Salah satu masalah lingkungan yang serius saat ini adalah pencemaran air yang dapat membahayakan kesehatan manusia dan organisme lainnya. Salah satu penyebab pencemaran air adalah adanya detergen dan logam berat yang terdapat di lingkungan. Karena dampaknya yang merugikan, perlu dicari solusi untuk menangani masalah ini. Salah satu solusinya adalah menggunakan teknik fitoremediasi dengan memanfaatkan tanaman daun tombak (Sagittaria lancifolia) yang terbukti mampu menyerap berbagai polutan dari lingkungan. Oleh karena itu, penelitian ini bertujuan untuk mengevaluasi efektivitas fitoremediasi tanaman daun tombak (Sagittaria lancifolia) dalam menangani kontaminasi detergen LAS (Linear Alkylbenzene Sulfonates) dan logam berat tembaga (Cu) pada air. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan empat perlakuan berbeda konsentrasi LAS + Cu, yaitu 0 mg/L, 10 mg/L + 3 mg/L, 30 mg/L + 3 mg/L, dan 50 mg/L + 3 mg/L. Hasil penelitian menunjukkan daya penyisihan LAS tertinggi sebesar 96% pada variasi konsentrasi LAS 10 mg/L + Cu 3 mg/L, dan daya penyisihan Cu tertinggi sebesar 72% pada variasi konsentrasi  LAS 50 mg/L + Cu 3 mg/L. lebih lanjut, nilai efektifitas penyerapan logam Cu tertinggi sebesar 59% pada variasi konsentrasi  LAS 50 mg/L + Cu 3 mg/L. Hasil penelitian juga menunjukkan semakin tinggi LAS yang diberikan maka semakin tinggi pula penyerapan logam berat Cu oleh tanaman. Berdasarkan hasil tersebut, terbukti bahwa tanaman daun daun tombak (Sagittaria lancifolia) efektif untuk menyerap LAS dan logam berat Cu di lingkungan.

Abstract

One of pollutant that commonly found in aquatic environment is detergent. Detergent pollution can cause skin irritation and other health problems in humans and animals that use contaminated water sources. To address this issue, it is critical to implement effective policies and regulations to control detergent pollution and promote sustainable wastewater management practices in Indonesia. One of the approaches to overcome detergent pollution is to use plants as pollutant absorbing agents, or commonly called phytoremediation techniques. Therefore, this study aims to determine the growth response of spear plant (Sagittaria lancifolia) in response to the stress of Linear Alkylbenzene Sulfonate (LAS) detergent. This research is an experimental research using a completely randomized design (CRD). There were four treatments tested with three replicates for each treatment. Treatment variations were based on the concentrations used in this study, namely 0 mg/L, 10 mg/L, 30 mg/L, and 50 mg/L. The research was conducted for four months, starting from July to October 2022, and was conducted in the greenhouse of Purwodadi Botanical Garden – BRIN. The result showed that although it experienced some morphological changes such as leaf drying, discoloration, and structural changes, Sagittaria lancifolia were able to survive and conduct metabolic activities properly during 28 days of Linear Alkylbenzene Sulfonates (LAS) pollutant stress.  Thus, Sagittaria lancifolia are able to be used as one of the strategies in restoring the aquatic environment polluted by domestic waste, including LAS detergent.
