Abstract

Laundry wastewater contains high levels of Chemical Oxygen Demand (COD) and phosphate (PO4), contributing to water pollution and eutrophication. This study investigates an integrated treatment approach using poly-aluminum chloride (PAC) coagulation and activated carbon adsorption to improve wastewater treatment efficiency. The research aims to determine the optimal PAC dosage (10% and 15%) and stirring time (0, 5, 15, 30, and 45 minutes) for maximizing COD and PO4 removal. A batch reactor system was used to conduct the treatment process, and the analysis followed the Indonesian National Standard (SNI) methods. The results demonstrated that the highest removal efficiencies were achieved with a 15% PAC dosage and a stirring time of 45 minutes. Under these conditions, COD levels were reduced from 2189.62 mg/L to 143.47 mg/L, achieving a 93% reduction. Similarly, PO4 levels decreased from 94.33 mg/L to 5.18 mg/L, corresponding to a 96% removal rate. These findings indicate that the combination of PAC coagulation and activated carbon adsorption is a highly effective treatment method for reducing pollution in laundry wastewater. This hybrid approach meets environmental discharge standards and presents a sustainable solution for large-scale wastewater treatment applications.

Abstract

Wilayah pesisir memiliki peran penting dalam sektor perikanan dan perekonomian masyarakat. Namun, pemanfaatan hasil laut yang kurang optimal serta pengelolaan limbah yang belum berkelanjutan masih menjadi tantangan utama. Penelitian ini bertujuan untuk menganalisis perilaku masyarakat pesisir berdasarkan tingkat pendidikan dan usia, yang mencakup (1) pengolahan limbah dan sampah, (2) pemilihan alat tangkap ikan, serta (3) pengolahan hasil tangkapan laut. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan teknik pengumpulan data melalui observasi, wawancara (kepada pelaku nelayan sebanyak 28 narasumber) dan dokumentasi. Teknik analisis yang digunakan adalah teknik analisis konten dengan software NVivo 12 plus. Hasil penelitian menunjukkan bahwa masyarakat dengan tingkat pendidikan menengah (SMP) dan kategori usia dewasa lebih aktif dalam pengelolaan limbah dan sampah. Pada pemilihan alat tangkap ikan, sebagian besar responden berpendidikan SMP dengan kategori usia dewasa menggunakan jaring sebagai alat utamanya. Pengolahan hasil tangkapan laut diolah menjadi ikan asap, didapatkan pada masyarakat berpendidikan SMP dan usia dewasa yang memiliki partisipasi tertinggi. Secara keseluruhan, temuan ini menegaskan bahwa perilaku masyarakat pesisir dalam memanfaatkan dan mengelola sumber daya perikanan tidak hanya ditentukan oleh pendidikan formal, tetapi juga oleh pengalaman hidup, pengetahuan lokal, usia produktif, dan kondisi sosial ekonomi yang berkembang dalam masyarakat pesisir
