PENGARUH KOMBINASI BIOCHAR LIMBAH KAYU DAN PUPUK KANDANG SAPI TERHADAP PERTUMBUHAN DAN HASIL TERUNG KENARI DI TANAH GAMBUT
Get PDFBiochar adalah arang hitam hasil dari proses pemanasan biomassa pada keadaan oksigen terbatas atau tanpa oksigen, yang berperan sebagai penyedia karbon dan sebagai pengganti bahan organik, dapat menjaga kelembaban tanah, dan membantu menyerap air dan menjerap unsur hara. Biochar juga meningkatkan ketersediaan hara mikro dan makro serta menjadi penyedia ekologi bagi pertumbuhan mikroorganisme. Tujuan dari penelitian ini adalah untuk mengetahui dosis pemberian kombinasi biochar limbah kayu dan pupuk kandang yang memberikan pertumbuhan dan hasil terung kenari yang terbaik di tanah gambut. Penelitian ini dilakukan di Lahan Penelitian Fakultas Pertanian Universitas Tanjungpura, Kalimantan Barat dan berlangsung selama tiga bulan (April 2019 sampai Agustus 2019). Penelitian ini menggunakan Rancangan Acak Lengkap dengan 6 macam perlakuan dan 4 ulangan dengan 4 sampel tanaman. Perlakuan yang diberikan adalah kombinasi dosis biochar limbah kayu dan pupuk kandang sapi yaitu 5 ton/ha biochar limbah kayu + 7,5 ton/ha pupuk kandang sapi (A), 5 ton/ha biochar limbah kayu + 15 ton/ha pupuk kandang sapi (B), 10 ton/ha biochar limbah kayu + 7,5 ton/ha pupuk kandang sapi (C), 10 ton/ha biochar limbah kayu + 15 ton/ha pupuk kandang sapi (D), 15 ton/ha biochar limbah kayu + 7,5 pupuk kandang sapi (E), dan 15 ton/ha biochar limbah kayu + 15 ton/ha pupuk kandang sapi (F). Hasil penelitian menunjukkan bahwa pemberian kombinasi biochar limbah kayu dan pupuk kandang sapi di tanah gambut berpengaruh nyata terhadap tinggi tanaman umur 4 MST akan tetapi tidak berpengaruh nyata pada variabel lainnya. Penelitian ini menunjukkan bahwa pemberian kombinasi biochar limbah kayu dan pupuk kandang sapi di tanah gambut memberikan pengaruh yang sama

No full textBudidaya tanaman jagung di tanah gambut dihadapkan pada masalah fisik dan kimia tanah yang kurang baik. Pemberian biochar sekam padi dan pupuk NPK pada tanah gambut diharapkan dapat memperbaiki sifat fisik dan kimia tanah sehingga pertumbuhan tanaman jagung dapat lebih optimal. Penelitian ini bertujuan untuk mengetahui takaran dosis kombinasi terbaik antara biochar sekam padi dan pupuk NPK untuk pertumbuhan dan hasil tanaman jagung. Penelitian ini dilaksanakan di Lahan Petani di Desa Rasau Jaya II Kecamatan Rasau Jaya Kabupaten Kubu Raya dimulai sejak tanggal 12 Mei - 9 Agustus Tahun 2019. Penelitian ini menggunakan rancangan faktorial Rancangan Acak Kelompok dengan 2 faktor perlakuan dan setiap kombinasi perlakuan diulang sebanyak 3 kali dan terdapat 6 tanaman sampel. Faktor pertama yaitu biochar sekam padi (b1= 5 ton/ha, b2= 10 ton/ha, b3= 15 ton/ha), dan faktor kedua pupuk NPK (p1= 400 kg/ha, p2= 300 , p3= 200 kg/ha). Variabel yang diamati meliputi tinggi tanaman, jumlah daun, kadar klorofil daun, berat kering tanaman, luas daun total, volume akar, berat tongkol berkelobot, berat tongkol tanpa kelobot, panjang tongkol, diameter tongkol dan berat tongkol per petak. Hasil penelitian menunjukkan bahwa perlakuan biochar sekam padi berpengaruh nyata terhadap variabel tinggi tanaman dan jumlah daun. Perlakuan pupuk NPK berpengaruh nyata terhadap variabel klorofil daun, tinggi tanaman, jumlah daun, berat tongkol berkelobot, dan panjang tongkol. Berdasarkan hasil pengamatan pemberian 10 ton/ha biochar sekam padi disertai dengan dosis pupuk NPK 200 kg/ha merupakan dosis yang efisien dalam meningkatkan pertumbuhan dan hasil tanaman jagung yang baik pada tanah gambut.

No full textEntomopathogenic nematodes are types of biological agents that live on the ground. The population can decrease exposure to chemicals in the form of pesticides that are too frequent. This study aims to determine the population density of EPN on peat land used for horticultural agriculture with the intensity of application of low, medium, and high pesticides (PI). The design of this study uses a Completely Randomized Design (CRD) with 3 preparations, and 15 replications, so that 45 samples will be obtained. Research parameters regarding bait insect mortality, population of NEP / ml, collection of NEP morphology, biochemical collection of bacterial symbionts, and soil analysis. The results showed that the highest PI was 51.7%, the lowest NEP density was 551 JI / ml and the lowest NEP diversity was only Steinernema carpocapsae. While on medium PI land and low PI land. mortality larvae reached 80.67 % and 78.7 %, and populations of 1.112 JI /ml and 752 JI / ml. The highest diversity was found in the medium PI land with two types of NEP, namely Steinernema carpocapsae and Heterorhabditis bacteriophora. While the abundance of the population of Steinernema carpocapsae is on low PI land

The experient was conducted from 15th November 2018 – 31st January 2019 in the experimental garden of the Faculty of Agriculture, Tanjungpura University, Pontianak. This study used a completely randomized design (CRD) method with one factor SP-36 phosphate fertilizer treatment consisting of 5 treatment levels, and 5 replications and each treatment consisted of 4 plant samples, so that there were 100 plants. The treatment in question is: p1 = 1.5 g / polybag equivalent to 100 kg / ha, p2 = 2.3 g / polybag equivalent to 150 kg / ha, p3 = 3 g / polybag equivalent to 200 kg / ha, p4 = 3 , 8 g / polybag is equivalent to 250 kg / ha and p5 = 4.5 g / polybag is equivalent to 300 kg / ha. The variables observed in this study were plant height (cm), root volume (cm3), plant dry weight (g), number of fruits per plant (fruit), weight per fruit (g), weight of fruit per plant (g). The results showed that the aplication of various SP-36 phosphate fertilizers gave the same result on all observation variables. However, it has a significant effect on root volume. The dosage of Phosphate SP-36 fertilizer has a better effect of 3 g / polybag equivalent to 200 kg / ha. Keyword : SP-36 Phosphate Fertilizer, Tomato, Peat Soi

PENGARUH KOMBINASI SUHU DAN DEHUMIDIFIKASI UDARA PENGERING TERHADAP AKTIVITAS ANTIOKSIDAN IRISAN BUAH MENGKUDU (Morinda citrifolia)
No full textBuah mengkudu segar kaya akan nutrisi dan komponen aktif serta mengandung kadar air tinggi. Tingginya kadar air mengakibatkan masa simpan yang singkat, sehingga perlu dilakukan pengeringan. Tujuan penelitian ini adalah untuk mengetahui pengaruh kombinasi metode dan suhu pengeringan terhadap aktivitas antioksidan irisan buah mengkudu. Metode pengeringan menggunakan tiga metode, yaitu metode konvensional, metode adsorpsi dan metode sirkulasi, sedangkan suhu pengeringan yaitu 50 °C, 57 °C dan 65 °C. Analisa data untuk asam askorbat, total flavonoid, dan aktivitas antioksidan menggunakan ANOVA (α=5%) dan uji BNJ (α=5%), sedangkan lama pengeringan dianalisa secara deskriptif. Hasil penelitian menunjukkan bahwa aktivitas antioksidan tertinggi dengan metode konvensional pada suhu 50 ºC yaitu sebesar 34% dengan karakteristik asam askobat sebesar 52,8 mg/100g buah mengkudu kering, total flavonoid sebesar 3,81 mg QE/g buah mengkudu kering, dan lama pengeringan selama 18 jam.Kata kunci: adsorben, antioksidan, mengkudu, pengeringan, suh
