Abstract

AbstrakKeberadaan gulma pada pembibitan kelapa sawit dapat menurunkan kualitas bibit. Pengendalian gulma di pembibitan awal harus dilakukan secara dengan tangan (hand weeding), karena bibit dapat mati akibat aplikasi herbisida. Aplikasi bioherbisida saliara (Lantana camara) pada bibit kelapa sawit (Elaeis guineensis Jacq.) dapat menjadi alternatif pengendalian gulma yang ramah lingkungan dan mengurangi tenaga kerja. Penelitian ini dilaksanakan di Kebun Percobaan 1 Politeknik CWE, pada November 2019 sampai Februari 2020. Percobaan disusun dalam Rancangan Acak Kelompok, dengan perlakuan: kontrol (tanpa aplikasi bioherbisida), Ekstrak Lantana camara 1%, 2%, dan 3%. Setiap perlakuan diulangi sebanyak tiga kali. Hasil penelitian menunjukkan bahwa Bioherbisida Lantana camara mengandung senyawa alelokimia yaitu Saponin (2,07%), Tanin (3,28%), dan Flavonoid (1,83%). Gulma Lantana camara dapat dijadikan bahan alternatif bioherbisida pra tumbuh karena berpengaruh nyata terhadap daya tumbuh gulma. Meskipun bioherbisida menurunkan tinggi bibit pada 3 bulan setelah tanam (BST) dan diameter batang bibit pada 1 BST, namun bioherbisida tidak mempengaruhi jumlah daun, kehijauan daun, dan biomassa bibit. Bioherbisida Lantana camara dengan konsentrasi 1% menunjukkan hasil terbaik dalam menekan laju pertumbuhan gulma.Kata Kunci: Bibit, Bioherbisida, Fisiologi, Gulma, Morfologi Abstract. The presence of weeds in oil palm nurseries can reduce the quality of the seedlings. Usually, mechanical weeding by hand is needed in pre-nursery because the use of chemical treatment caused the oil palm seeeling died. Bioherbicide application of Lantana camara to oil palm seedling (Elaeis guineensis Jacq.) can be alternative weed control that is environmental friendly and reduces labor. This research conducted at Teaching Farm Politeknik CWE, from November 2019 to Februari 2020. Experiment was arranged in Randomized Block Design, with treatments are Control (without bioherbicide application), Bioherbicide Lantana camara 1%, 2% and 3%. Every treatments was repeated three times. The results showed that Lantana camara bioherbicide contained allelochemical compounds, namely saponins (2.07%), tannins (3.28%), and flavonoids (1.83%). Lantana camara weed can be used as an alternative material for pre-growing herbicides because it has a significant effect on reduced weed population. Although bioherbicides decreased seedling height at 3 months after planting (MAP) and stem diameter at 1 MAP, bioherbicides did not affect leaf number, leaf greenness, and seedling biomass. Bioherbicide Lantana camara with concentration 1% showed the best treatment for controlling weeds in oil palm pre nursery.Keywords: Bioherbicide, Morphology, Physiology, Seedlings, Weed

Abstract

Kegiatan penyemprotan umumnya menggunakan alat semprot knapsack sprayer yang memiliki nozzle untuk mengubah larutan menjadi butiran semprot. Pemilihan nozzle harus tepat agar butiran semprot yang dihasilkan sesuai dengan target penyemprotan. Nozzle polijet dan flat fan adalah dua nozzle yang umumnya digunakan oleh masyarakat. Kalibrasi kedua nozzle tersebut dibutuhkan agar mengetahui kualitas dan kuantitas volume semprot yang dihasilkan. Tujuan penelitian ini adalah mengetahui perbedaan lebar semprotan, volume semprot dan mendapatkan rekomendasi nozzle yang tepat berdasarkan hasil kalibrasi. Penelitian ini dilaksanakan mulai bulan Januari 2021sampai Maret 2021 di areal percobaan Kabupaten Labuhan Batu Selatan, Sumatera Utara. Penelitian ini disusun dalam rancangan acak kelompok (RAK) non faktorial yang terdiri dari dua perlakuan yaitu : P1  (polijet) dan P2 (flat fan). Setiap perlakuan diulang sebanyak 5 kali, sehingga terdapat 10 kali percobaan. Data dianalisis menggunakan Uji T pada taraf 5%. Hasil penelitian menunjukkan bahwa nozzle polijet menghasilkan lebar semprot, flowrate, konsentrasi dan kebutuhan bahan per tangki yang lebih kecil dibandingkan flat fan, namun menghasilkan volume semprot yang lebih besar. Berdasarkan hasil perhitungan kalibrasi, nozzle polijet lebih direkomendasikan karena membutuhkan bahan (herbisida) yang lebih sedikit sehingga aman bagi lingkungan dan menghemat biaya.

Abstract

Controlling weed using herbicide by continuously would be had negative affect for environment and make weed resistance. This problem must be resolved with more eco-friendly solution, such as using pre-emergence bioherbicide. Bioherbicides are herbicides derived from natural ingredients and contain chemical compounds that capable of controlling weeds, such as Imperata cylindrica, because it is contains allelochemical that inhibit the growth of others plant. The research was arranged in a non factorial randomized design with two replication, which consists of 5 treatments, namely, A0 (control), A1 (herbicide Glyphosate 1%), A2 (bioherbicide extract 1%), A3 (bioherbicide extract 3%), A4 (bioherbicide extract 5%). Data were analyzed using analysis of variance and a further test DMRT (Duncan Multiple Range Test). The results from this study showed that alang-alang (Imperata cylindrica L.) could be alternative bioherbicides for controlling weed in oil palm plantation. Pre-emergence bioherbicides significantly affect the growth of weeds in 7 and 21 days after application. The best bioherbicides concentration is 1%, and its bioherbicides contains of alelochemical is flavonoid.

Abstract

Imperata cylindrica is belongs to the class A weed group (very dangerous). Control of weeds regularly continues, and this causes high weed waste in plantations. One of the activities carried out to handle it is to use it as mulch to maintain moisture and reduce weed growth. Mulch application will be more optimal if combined with tillage, because weed seeds in the soil will be cut off and fail to germinate. The combination of these two activities is expected to be able to control the growth of weeds and maintain good soil conditions. This study aims to obtain alternative pre-growing weed control, determine the effectiveness of mulch application and soil management activities in controlling weeds. This research was conducted in Experimental Garden 2 and Biology Laboratory of Polytechnic Kelapa Sawit Citra Widya Edukasi Bekasi, from April to May 2017. The research was arranged in a Factorial Randomized Block Design (RBD), the first factor was the application of mulch consisting and the second factor is tillage The results of the experiment showed that the application of mulch Imperata cylindrica and tillage can be used as an alternative activity to control weeds and the real interaction between the two activities can be seen in the number of weeds 1 Week After Planting (1 WAP). Mulch application has a single significant effect on the number of weeds 2 and 3 WAP, whereas tillage does not show any significant effect on all parameters.
