This study aims to determine the toxicity of the formulated herbicide concentration to nontarget organisms earthworms. The study was conducted from April to July 2021. The design used was a completely randomized design (CRD) with nine (9) herbicide concentrations (K) treatments, namely: K0 = control, K1 = 200 ppm concentration (0.2 ml/l water ), K2 = concentration of 400 ppm (0.4 ml/ l of water), K3 = concentration of 600 ppm (0.6 ml/ l of water), K4 = concentration of 800 ppm (0.8 ml/ l of water), K5 = concentration 1000 ppm (1.0 ml/ l of water), K6 = concentration of 1200 ppm (1.2 ml/ l of water), K7 = concentration of 1400 ppm (1.4 ml/ l of water), K8 = concentration of 1600 ppm (1, 6 ml/l water). Each treatment was repeated 3 times. Observations were made on the fourth day after application. The observed variables were the concentration of death 50 (LC50) for 96 hours, survival rate, mortality percentage and worm weight. This study concluded that the concentration of death 50 (LC50) for 96 hours of the formulated herbicide against earthworms was 600 ppm, while the 100% mortality occurred at the herbicide concentration of 1400 ppm. The lowest survival rate was found at a concentration of 1400 ppm, where at that concentration all the test worms died. Meanwhile, the highest survival rate after herbicide was given at a concentration of 200 ppm where the mortality of worms was 20%. The higher the concentration of herbicide formulation given to earthworms, the higher the mortality rate and decrease in body weight.

“…Penggunaan herbisida sintetis secara terus menerus dapat berakibat negatif bagi lingkungan seperti pencemaran lingkungan, polusi sumber-sumber air dan kerusakan tanah, (Kurniawan, Kurniawati, Sandri, & Fatimah, 2014). Selain itu herbisida sintetis juga mengakibatkan tertinggalnya residu sehingga mengakibatkan keracunan pada organisma non target dan mempengaruhi aktifitas biota tanah serta tertinggalnya residu herbisida pada produk pertanian (Sari, Niswati, Arif, & Yusnaini, 2015;Faqihhudin, Haryadi, & Purnamawati, 2014).…”

This study aims to determine the effectiveness of biological herbicide formulas on smallholder coffee plantations in various agro-ecological conditions, namely smallholder coffee fields in the medium plains and plateau. The study concluded that the weeds found in the medium plains coffee fields were 17 species. The dominant weeds were Cynodon dactilon 38.1%, Asystasia gangetica 19.3%, Ageratum conyzoides 10%, Borreria latifolia 5.4%, Acmella paniculata 3.3%, and Clydemia hirta 3.3%. These six types of weeds dominate the land at 79.4%. Meanwhile, in the plateau, there were 20 types of weeds. The dominant weeds were

Penelitian sebelumnya telah menemukan herbisida jenis baru berbahan baku utama air kelapa fermentasi, mengandung bahan organik, mikroorganisme, dan ramah lingkungan. Serangkaian pengujian perlu dilakukan untuk melihat efektifitasnya. Penelitian ini bertujuan untuk mengetahui herbisida formulasi terbaik dalam mengendalikan gulma pada gulma darat dan gulma air di multi lokasi. Percobaan menggunakan Rancangan Acak Kelompok, terdiri dari sembilan perlakuan formulasi herbisida (Unihaz) dengan tiga ulangan. Perlakuan tersebut adalah Unihaz 1, Unihaz 2, Unihaz 3, Unihaz 4, Unihaz 5, Unihaz 6 , Unihaz 7, Unihaz 8 (glifosat 2 kg ha-1) dan Unihaz 9 (air kelapa fermentasi). Hasil penelitian menyimpulkan bahwa herbisida formulasi Unihaz 7 efektif mengendalikan gulma baik di lahan kering (gulma darat) maupun di lahan basah (gulma air) di berbagai ketinggian tempat, dan dapat mengendalikan gulma di atas 90%. Herbisida formulasi Unihaz 7 lebih baik dalam mengendalikan gulma di lahan sawah dibandingkan dengan penggunaan glifosat dosis 2000 g ha-1.
