Abstract

A series of studies had been carried out to create new types of herbicides. The studies had found six formulations ofherbicides. This study aimed to determine the effectiveness of herbicides formulation in controlling aquatic weeds. Theexperiment used a randomized complete block design with seven herbicide formulations as treatments and three replications.The seven formulations of herbicide were: Unihaz 1, Unihaz 2, Unihaz 3, Unihaz 4, Unihaz 5, Unihaz 6, and a control(glyphosate 2 kg ha-1). The results of the study found that there were 21 species of weed in rainfed swamps, ten species inbrackish swamps and one species namely water hyacinth (Eichhornia crassipes) in drainage channel. Herbicide formulationsof Unihaz 3, 4, 5, and 6 were effective in controlling aquatic weeds in rainfed swamps. Herbicide formulations of Unihaz 2, 3and 5 were effective in controlling aquatic weeds in brackish swamps. All herbicides formulations were effective in controllingweeds in drainage channels. Moreover, herbicide formulation of Unihaz 5 was more effective in controlling aquatic weeds inrainfed swamps, brackish swamps and drainage channels than other formulations, and it was not significantly different fromthe use of a glyphosate dose of 2 kg ha-1.Keywords: Eichhornia crassipes, fermented coconut water, organic herbicide, new types of herbicides

Abstract

Penelitian sebelumnya diperoleh empat paket teknologi bokashi limbah kandang kelinci. Keempat paket teknologi ini perlu diuji untuk mengetahui paket teknologi yang mana yang terbaik untuk tanaman jagung manis. Selain itu perlu juga perlu diketahui dosis berapa yang terbaik dalam budidaya jagung manis tersebut. Penelitian dilaksanakan di desa Talang Ratu, Kecamatan Lebong Selatan, Kabupaten Lebong pada bulan Februari sampai Oktober 2017. Penelitian menggunakan Rancangan Petak Terbagi (Split Plot Design). Sebagai Petak Utama adalah Paket Teknologi Bokashi Limbah Kelinci (P) terdiri dari: P1= Paket Teknologi I; P2 = Paket Teknologi II; P3 = Paket Teknologi III; P4 = Paket Teknologi IV. Sebagai anak petak adalah Dosis Pupuk (D) terdiri dari: D0 = Kontrol (Tanpa Pupuk); D1 = Dosis 5 ton/ha; D2 = Dosis 10 ton/ha; D3 = Dosis 15 ton/ha; D4 = Dosis 20 ton/ha; D5 = Dosis 25 ton/ha; D6 = Pupuk Anorganik, dosis Urea 400 kg/ha, SP36 350 kg/ha dan KCl 100 kg/ha. Hasil penelitian menyimpulkan: (1) Paket teknologi pupuk bokashi berbahan baku kelinci berpengaruh tidak nyata terhadap pertumbuhan dan hasil tanaman jagung manis. (2) Perlakuan dosis pupuk bokashi berpengaruh nyata terhadap pertumbuhan dan hasil tanaman jagung manis. (3) Interaksi perlakuan paket teknologi dan dosis berpengaruh sangatnya terhadap pertumbuhan dan hasil tanaman jagung manis. (4) Kombinasi perlakuan terbaik untuk pertumbuhan dan hasil tanaman jagung adalah perlakuan Paket Teknologi III dengan dosis 15 ton/ha (P3D3)

Abstract

The aim of this study was to examine the effect of bokashi residue from a mixture of cow dung and Oil Palm Empty Fruit Bunches (TKKS) whose raw materials were taken from the Cattle-Palm Integration System on changes in soil chemical properties and content of N. P, K and Mg palm plants. This study used a Completely Randomized Block Design (RAK) with one factor and 6 treatments, namely : F0 = Control (N,P,K,Mg), F1 = Cow dung only, F2 = 1/3 part of cow dung + 2/3 part of TKKS waste, F3 = 1/2 part of cow dung + 1/2 part of TKKS waste, F4 = 2/3 part of cow dung + 1/3 part of TKKS waste, and F5 = Only TKKS waste. The results showed that the bokashi residue of a mixture of cow dung and oil palm empty fruit bunches had a very significant effect on changes in soil pH, and no significant effect on changes in soil Al-dd, nutrient content of N, P, K, and Mg of immature oil palm plantations. The control treatment (F0), namely the use of chemical fertilizers NPK and Mg showed the smallest change in soil pH and was significantly different from other treatments in all tested formulas. Changes in NPK and Mg elements did not show any effect of giving bokashi but there was a tendency to add nutrients to the bokashi treatment which showed that the residue of bokashi mixture of cow dung and empty oil palm fruit bunches was able to last up to 24 months after application. It is recommended to re-apply bokashi a mixture of cow dung and oil palm empty fruit bunches on immature oil palm plants every 2 years.

Abstract

The Application of Environmentally Friendly Herbicide in Farmers Group of Kungkai Baru Village, Air Periukan Subdistrict, Seluma Regency This service program aimed to overcome the problem of aquatic weeds that disrupt the drainage canal and ponds of farmers without killing non-target organisms. The ultimate goal was that farmers wanted to apply weed control techniques using an effective and environmentally friendly herbicide of Unihaz formulation. The method implemented was a demonstration plot. The location of spraying herbicides was chosen on the drainage channel which was already filled with floating aquatic weeds. The number of plots prepared was 3 plots. Two plots were applied with the Unihaz herbicide formula, while one more was applied with synthetic herbicides made from glyphosate. The dosage used for the herbicide Unihaz formulation is 50 l ha-1, while the synthetic herbicide is 6 l ha-1. The dedication program concluded that the farmer group understood about herbicides that were effective and environmentally friendly. The farmer group has also proven that the herbicide of Unihaz formulation was able to control floating weeds in the drainage channel equivalent to the herbicide containing active ingredients glyphosate.
