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.","PeriodicalId":33886,"journal":{"name":"Jurnal Agroqua","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86895274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Selain itu aliran air waduk juga digunakan untuk kegiatan perikanan dan pertanian. Dalam pengelolaan suatu perairan yang lestari dan berkelanjutan diperlukan informasi dasar mengenai tingkat kesuburan perairan guna pemanfaatan yang tepat. Penelitian ini bertujuan untuk mengetahui kualitas air dan status kesuburan perairan di Waduk Joto Kabupaten Lamongan. Metode pengumpulan data menggunakan purposive random sampling pada tiga stasiun yaitu bagian inlet, tengah, dan outlet. Penentuan status kesuburan perairan berdasarkan perhitunganmenggunakan Carlson Trophic State Index (TSI). Pengambilan sampel air dilakukan dengan interval waktu satu bulan sekali selama 3 bulan pada bulan Desember 2020 sampai Februari 2021. Parameter yang diamati meliputi suhu, kecerahan, pH, salinitas, oksigen terlarut (DO), nitrat, total fosfat, klorofil-a. Hasil penelitian menunjukkan bahwa status kesuburan perairan Waduk Joto pada bulan Desember 2020 – Februari 2021 berdasarkan TSI Carlson termasuk dalam kategori perairan hipereutrofik dengan nilai sebesar 74. Disarankan untuk melakukan penelitian lanjutan pada musim yang berbeda untuk mengetahui status kesuburan perairan di musim kemarau.","PeriodicalId":33886,"journal":{"name":"Jurnal Agroqua","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87504680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pengelolaan yang salah dapat mengakibatkan tanah gambut mengalami cekaman kekeringan. Pendekatan teknologi yang dapat digunakan untuk mengoptimalkan penggunaan tanah gambut yang mengalami cekaman kekeringan pada tanaman jagung dapat dilakukan dengan pemberian formulasi pupuk hayati. Tujuan penelitian ini adalah untuk mendapatkan formulasi pupuk hayati untuk meningkatkan pertumbuhan dan produksi jagung pada kondisi cekaman kekeringan di tanah gambut. Penelitian ini dilakukan dikebun percobaan Universitas Bina Insan. Penelitian ini menggunakan Rancangan rancanagan acak kelompok faktorial dengan 2 faktor perlakuan yaitu faktor perlakuan pertama pupuk hayati yaitu H0: tanpa pupuk hayati, H1: Mikoriza + Petrobio, H2: Mikoriza + Agrozeabiochar, H3: Mikoriza + Pugam. Faktor perlakuan kedua yaitu intensitas penyiraman yaitu W1: intensitas penyiraman setiap hari, W2: intensitas penyiraman 1 kali 3 hari, P3: intensitas Penyiraman 1 kali 5 hari, P4: inensitas Penyiraman 1 kali 7 hari. Faktor kedua perlakuan diulang 4 kali. Jumlah keseluruhan tanman yang adalah diperoleh 64 tanaman. Hasil penelitian yang diperoleh adalah pemberian formulasi pupuk hayati setelah dianalis pada tingkat taraf 5% memberikan hasil yang berbeda nyata pada pertambahan tinggi tanaman dan namun pada pertambahan diameter batang berat kering akar. Sedangkan untuk intensitas penyiraman menunjukkan pengaruh nyata pada parameter tinggi tanaman, pertambahan diameter batang, luas daun, dan berat kering akar.
