Abstract

This study aims to determine the best concentration of coconut water on growth and yield plan cutting of mint. This study held from on February 25st to April 25th 2019. The research was conducted in Purnama Agung VII, Komplek Pondok Agung Permata, South Pontianak. The method use is  randomized completely design of one factor,the treatment consisted of 5 treatments, namely  (p1 = concentrations of  coconut water 0%, p2 = concentrations of  coconut water 12,5%, p3 = concentrations of  coconut water 25%, p4 = concentrations of  coconut water 37,5%, p5 = concentrations of  coconut water 50%,) all treatmets were repeated 5 times, each treatment consisting of 4 plant samples. The results showed that the concentrations of  25% coconut water was the best concentration for improving yield of cuttings of mint plants.  Keywords: Coconut Water, Plant Cutting of Mint.

Abstract

The use of a single herbicide often cannot control all types of weeds. Increase the effects of weed control. This study aims to study the effectiveness of glyphosate and methyl metsulfuron herbicides to control the Ischaemum timorense weed and determine the nature of the mixture. This research was conducted from January to April 2019, for ± 4 months in the greenhouse and Pesticide Laboratory of the Faculty of Agriculture, Tanjungpura University, Pontianak. The research was arranged in random groups. The treatment consisted of 4 types of herbicides with five dose levels and 1 control, namely glyphosate (0, 0.188, 0.375, 0.750, 1.5, 3.0) l / ha, methyl metsulfuron (0, 10, 20, 40, 80, 160) g / ha, herbicide mixture A 240/10 SL (0, 0.25, 0.50, 1.00 2.00, 4.00) l / ha and mixed herbicide B 360/10 SL (0, 0 , 25, 0.50, 1.00, 2.00, 4.00) l / ha. The target weed is Ischaemum timorense, a grass weed which is planted in a 14 cm diameter pot and a target of 3 MST (Three weeks after planting a herbicide test is applied). The variables observed are the level of weed damage that was assessed through phytotoxicity scoring and weed dry weights and analysis of herbicide mixture properties. The results showed that the higher the dose of the herbicide that was given, the more effective the suppressor was in controlling weeds. Herbicides that have been able to restore weed growth include glyphosate (G3) at a dose of 0.750 l / ha, Methyl metsulfuron (M5) at a dose of 160 g / ha, A mixture of 240/10 SL (CG3) at a dose of 1.0 l / ha , Mixture B 360/10 SL (CB3) at a dose of 1.0 l / ha. A mixed herbicide A 240/10 SL with an LD50 value of 93.2 and a mixture of B 360/10 SL is 186.92 smaller than the LD50 value of a single glyphosate herbicide 186.83 and methyl metsulfuron 27.98. The index value of combination herbicide mixture A 240/10 SL is 1.0384 and herbicide mixture B 360/10 SL is 1.0262, thus the nature of the herbicide is not antagonistic.Keywords: Glyphosate, Methyl metsulfuron, LD50, Herbicide mixture.

Abstract

Penggunaan dolomit dan pupuk fosfat dalam budidaya tanaman kacang tanah pada tanah gambut dapat meningkatkan pH tanah sehingga dapat menyerap unsur hara salah satunya fosfat, dimana fosfat dapat meningkatkan pertumbuhan dan hasil tanaman kacang tanah. Tujuan penelitian untuk mendapatkan dosis dolomit dan pupuk fosfat yang terbaik dalam meningkatkan pertumbuhan dan hasil tanaman kacang tanah pada tanah gambut. Lokasi penelitian terletak di Jalan Khatulistiwa Gang Karya Usaha, Kelurahan Batulayang, Kecamatan Pontianak Utara. Waktu penelitian mulai dari tanggal 26 Maret - 3 Juli 2020. Rancangan penelitian menggunakan Rancangan Acak Kelompok, dengan kombinasi dosis dolomit dan pupuk fosfat yang terdiri dari 9 perlakuan  yaitu  a1b1  (10  ton/ha + 100 kg/ha);  a1b2  (10 ton/ha + 200 kg/ha);  a1b3  (10 ton/ha + 300 kg/ha);  a2b1  (15 ton/ha + 100 kg/ha);  a2b2 (15 ton/ha + 200 kg/ha); a2b3 (15 ton/ha + 300 kg/ha); a3b1  (20  ton/ha + 100 kg/ha);  a3b2  (20 ton/ha + 200 kg/ha); dan  a3b3  (20 ton/ha + 300 kg/ha). Setiap perlakuan diulang sebanyak 3 kali dan setiap ulangan terdiri dari 25 tanaman per petak. Variabel yang diamati dalam penelitian ini adalah volume akar, berat kering tanaman, jumlah polong per tanaman, berat polong kering, berat biji kering per tanaman, berat 100 butir biji kering, dan berat biji kering per petak. Hasil Penelitian menunjukkan bahwa semakin tinggi dosis dolomit dan pupuk fosfat yang diberikan akan meningkatkan pertumbuhan dan hasil kacang tanah. Dosis yang efektif ditunjukkan pada pemberian 15 ton/ha dolomit dan 200 kg/ha fosfat berdasarkan potensi hasil tanaman kacang tanah yaitu berat biji kering 4,4 ton/ha. Kata Kunci : dolomit, fosfat, gambut, kacang tanah.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dosis kotoran burung walet yang terbaik untuk pertumbuhan dan hasil tanaman cabai rawit pada tanah aluvial. Penelitian ini berlangsung mulai 10 Oktober 2019 sampai 9 Januari 2020. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Tanjungura Pontianak. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari satu faktor yaitu kotoran burung walet terdiri dari 5 perlakuan, 5 ulangan, dan setiap perlakuan terdiri dari 4 sampel tanaman, jumlah keseluruhan ada 100 tanaman. Perlakuan terdiri dari B1 (205 g/polybag), B2 (432 g/polybag), B3 (659 g/polybag), B4 (886 g/polybag) dan B5 (1.113 g/polybag). Variabel pengamatan yang diamati dalam penelitian ini adalah tinggi tanaman (cm), volume akar (cm3), berat kering tanaman (g), berat buah per tanaman (g), jumlah buah per tanaman (buah) dan berat rerata per buah (g). Hasil penelitian pemberian kotoran burung walet pada cabai rawit memberi respon yang baik pada variabel volume akar, berat buah per tanaman dan jumlah buah per tanaman. Dosis kotoran burung walet 886 g/polybag setara dengan 253.21 ton/ha merupakan dosis terbaik untuk pertumbuhan dan hasil cabai rawit pada tanah aluvial.Kata Kunci : aluvial, cabai rawit, kotoran burung walet
