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.

Abstract

This study aims to determine the dosage of herbicides made from fermented coconut water against weeds in immature oil palm plantations. The research was conducted in March 2022, in Sukarami Village, Kedurang Ilir District, South Bengkulu Regency, Bengkulu Province. The experiment used a randomized block design with one factor, namely herbicide dose (D), consisting of 9 treatments: D1 = 10 L/ha, D2 = 15 L/ha, D3 = 20 L/ha , D4 = 25 L/ha, D5 = 30 L/ha, D6 = 35 L/ha, D7 = 40 L/ha, D8 = 45 L/ha, D9 = 50 L/ha. The results of the study concluded that smallholder oil palm plantations were dominated by Axonopus compresus (47.78%) and Ageratum conyzoides (30.98%). The weed that is resistant to this herbicide is Erigeron bonariensis L. The dose treatment has a significant effect on weeds in immature smallholder oil palm plantations. Treatment at a dose of 25 L/ha is effective in controlling weeds in immature oil palm plantations.

Abstract

This study aims to determine the effect of doses of bioherbicide formulated by Unihaz in controlling weeds, as well as to determine the dose of bioherbicide formulated by Unihaz which is effective in controlling weeds. This study used a single factor Completely Randomized Design (CRD), namely the Unihaz formulation bioherbicide dose treatment, consisting of 7 levels with 4 replications. The treatments were: dose 1 (40 l/ha), dose 45 l/ha, dose 50 l/ha, dose 55 l/ha, dose 60 l/ha, dose 60 l/ha, and dose 70 l/ha. The data obtained were then analyzed using Fisher's test (F), followed by Duncan's Multiple Range Test (DMRT) with a test level of 5%. The results of this study concluded that the use of a dose of 70 l/ha showed the highest weed mortality rate and the lowest live weed population, the lowest weed wet weight and dry weight which were significantly different from other dose treatments, making it the most effective in controlling grassy grass weeds

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh macam pengolahan tanah dan dosis kalium terhadap pertumbuhan dan hasil tanaman jagung manis pada tanah subsoil ultisol. Percobaan menggunakan Rancangan Petak Terbagi (Split Plot) dengan 3 ulangan. Sebagai Petak utama adalah macam pengolahan tanah terdiri dari 3 taraf yaitu: tanpa pengolahan tanah, pengolahan tanah minimum, pengolahan tanah maksimum. Sebagai anak petak adalah Dosis pupuk Kalium terdiri dari 4 taraf yaitu: tanpa pupuk (kontrol), dosis 75 kg/ha, Dosis 150 kg/ha, dan Dosis 225 kg/ha. Data hasil penelitian dianalisis dengan Analisis Keragaman untuk mengetahui apakah perlakuan tersebut berpengaruh nyata atau berpengaruh tidak nyata. Apabila hasil analisis berpengaruh nyata atau sangat nyata maka dilanjutkan dengan uji lanjut Duncant’s Multiple        Range Test (DMRT) pada taraf 5%. Penelitian ini menyimpulkan bahwa: pengolahan tanah maksimum berpengaruh nyata terhadap tinggi tanaman 8 mst, jumlah daun fase berbunga, dan lingkar tongkol, serta sangat nyata pada lebar daun, berat tongkol berkelobot per tanaman, dan bobot tongkol tanpa kelobot per tanaman jagung manis yang ditanam pada tanah sub soil ultisol. Dosis pupuk kalium 225 kg/ha berpengaruh nyata dan sangat nyata pada peubah tinggi tanaman 4 mst, 6 mst, 8 mst, bobot tongkol berkelobot dan berat tongkol tanpa kelobot. memberikan tinggi tanaman  4 mst, 6 mst, 8 mst, bobot tongkol berkelobot dan berat tongkol tanpa kelobot tertinggi pada jagung manis yang ditanam pada tanah subsoil ultisol. Interaksi macam pengolahan tanah dan dosis kalium  berpengaruh pada peubah bobot tongkol berklobot pertanaman dan berat tongkol tanpa kelobot per tanaman. Macam pengolahan tanah maksimum dan dosis kalium 225 kg/ha memberikan bobot tongkol berkelobot per tanaman dan berat tongkol tanpa kelobot per tanaman tertinggi.

Abstract

This research aims to determine the effect of potassium fertilizer doses on the growth and yield of watermelon plants planted in ultisol soil, and determine short-term changes in weed composition.The experiment used a Randomized Block Design (RAK) with five treatments of potassium (D) doses and three replications. The treatment doses are: Without fertilizer (control) equivalent to 0 kg/plot; A dose of 125 kg/ha is equivalent to 37.4 g/plot; A dose of 250 kg/ha is equivalent to 74.8 g/plot; A dose of 375 kg/ha is equivalent to 112.1 g/plot; A dose of 500 kg/ha is equivalent to 149.5 g/plot. The research data was analyzed using Sidik Ragam to find out whether the treatment had a real effect or an insignificant effect. If the results of the analysis have a real or very real effect, then continue with the Duncant's Multiple Range Test (DMRT) at the 5% level.This research concluded: (1) The dose of potassium fertilizer had no significant effect on plant length and fruit weight per plant but had a very significant effect on fruit weight per plot. Potassium fertilizer dose of 500 kg/ha provides the highest fruit weight per plot; (2) Potassium fertilizer doses tend to provide different weed populations and dry weights in watermelon plantings. The higher the dose of potassium fertilizer given tends to increase the weed population and weed dry weight; (3) The weed community coefficient index between mid and late weeds in watermelon planting is the same. However, the number of weed populations and biomass in the middle observation was higher than the final observation of watermelon planting.

Abstract

This study aimed to evaluate the effectiveness of various herbicide formulations based on fermented coconut water, acetic acid, ethanol, glyphosate, and salt against weeds in open fields. The study used a Randomized Block Design with 9 formulations and 3 replications. Observed variables included dominant weeds, dead weed area, live weed population, dry weight of live weeds, and chlorophyll degradation. The results showed that four types of weeds dominated the field (96%): Paspalum conjugatum, Mimosa pudica, Cyperus rotundus, and Chrysopogon aciculatus. Herbicide formulations significantly suppressed weed growth. Formulations 3 and 9 proved to be the most effective. Further development of Formulations 1, 3, 4, 5, 7, and 8 is recommended.
