ABSTRAK
Limbah cair hasil dari proses pembuatan tahu yang dibuang langsung ke sungai akan menimbulkan pencemaran. Untuk mencegah potensi dampak tersebut, diperlukan pengolahan yang tepat guna yakni pengolahan secara fitoremediasi. Rumusan masalah dalam penelitian ini adalah apakah ada perbedaan efektivitas tanaman Eceng Gondok (Eichhornia crassipes) dengan berat 300 gr, 500 gr, dan 700 gr dalam menurunkan kadar Biochemical Oxygen Demand (BOD) limbah cair industri tahu. Tujuan penelitian ini untuk menganalisis efektivitas Eceng Gondok (Eichhornia crassipes) dalam menurunkan kadar Biochemical Oxygen Demand (BOD) limbah cair industri tahu dengan variasi berat tanaman yang berbeda.
Penelitian ini merupakan penelitian ekperimental dengan desain penelitian Rancangan Acak Kelompok dengan 3 kali pengulangan setiap 10 hari. Lokasi pengambilan sampel Eceng gondok adalah di danau Limboto dan pengambilan sampel limbah tahu adalah di Pabrik ME. Pengujian sampel dilakukan di Laboratorium Kesehatan Daerah Provinsi Gorontalo.
Hasil uji One Way Anova menunjukkan nilai signifikansinya 0,931 (p>0,05), menyatakan tidak ada pengaruh perbedaan berat eceng gondok dalam menurunkan kadar Biochemical Oxygen Demand (BOD) limbah cair industri tahu. Uji LSD menunjukkan variasi berat yang paling baik dalam menurunkan BOD adalah 300 gram. Peneliti berharap agar pemilik industri tahu menyediakan alternative pengolahan limbah agar meminimalisir pencemaran yang ada.

ABSTRACT
Liquid waste resulting from the process of making tofu which is dumped directly into the river will cause pollution. Appropriate treatment is needed to prevent the potential impact, namely phytoremediation processing. The formulation of the problem in this study is whether there is a difference in the effectiveness of the water hyacinth plants (Eichhornia crassipes) with a weight of 300 gr, 500 gr, and 700 gr in reducing the levels of Biochemical Oxygen Demand (BOD) in tofu liquid waste industry. The purpose of this research is to examine the effectiveness of the water hyacinth plants (Eichhornia crassipes) in reducing the levels of Biochemical Oxygen Demand (BOD) in Tofu Liquid Waste Industry.
This study was an experimental study with a randomized group design research with three repetitions every ten days. The location of water hyacinth sampling is in Limboto lake, and tofu waste sampling is at the ME Factory. Sample testing was conducted at the Regional Health Laboratory of Gorontalo Province.
The One Way ANOVA shows the significant value of 0,931 (p>0,05) which means there are no significant differences between the weight of water hyacinth plants in reducing the levels of Biochemical Oxygen Demand (BOD) in tofu liquid waste industry. The LSD test shows the best weight variation in reducing BOD is 300 grams. It is expected that tofu industry owners will provide waste treatment alternatives to minimize existing pollution.
