Abstract

The presence of weeds in immature oil palm plantations needs to be controlled, otherwise it results in competition with the main crop. Herbicide active ingredients, especially glyphosate, are widely used to reduce weed growth in oil palm plantations.. This study aimed to determine the dose of isopropylamine glyphosate herbicide that effectively controls weeds in oil palm plantations, changes in weed composition, and phytotoxicity due to the application of isopropylamine glyphosate herbicide in immature oil palm plantations. This trial was conducted in Oil Palm Plantation, Karang Anyar Village, Jati Agung District, South Lampung Regency and Weed Laboratory, Faculty of Agriculture, University of Lampung, September - December 2022. The trial was conducted using a randomized block design (RBD) with 4 replications and 6 treatments, namely several dose levels of isopropylamine glyphosate herbicide (787,5; 1.050; 1.312,5; and 1.575 g ha-1), mechanical weeding, and untreatment. Homogeneity of data variance was tested with Bartlett's test, additivity of data was tested with Tukey's test, and differences in treatment mean values were tested with the Least Significant Difference (LSD) test at the 5% level.The trial showed that isopropylamine glyphosate herbicide doses of 787,5 - 1.575 g ha-1 effectively controlled total weeds, grasses (Axonopus compressus and Ottochloa nodosa), and sedge (Cyperus kyllingia), as well as broad leaves (Asystasia gangetica and Melastoma affine) at dose levels of 1.312,5 and 1.575 g ha-1 at (4, 8, and 12) week after application, isopropylamine glyphosate herbicide doses of 787,5 - 1.575 g ha-1 caused changes in weed composition, and did not cause poisoning of immature oil palm plants after being applied to the crop disk until 12 week after application.

Abstract

Permasalahan petani agroforestri kopi Kabupaten Tanggamus yaitu produktivitas kopi yang menurun sehingga berpengaruh pada perekonomian masyarakat. Tim PKM Universitas Lampung mengajukan teknik kesehatan hutan berbasis regenerative-resilient untuk memecahkan permasalahan tersebut. Tujuan kegiatan ini yaitu meningkatkan pendapatan petani agroforestri kopi melalui penerapan teknik kesehatan hutan berbasis regenerative-resilient. Metode yang digunakan dalam kegiatan ini adalah penyuluhan dan pelatihan. Peserta pelatihan dalam kegiatan ini mendapatkan pengetahuan dan keterampilan dalam pemilihan klon, entres, teknik grafting, jenis pupuk, dan juga metode pemupukan. Selain itu petani juga memahami jenis tanaman yang dapat dikombinasikan dengan kopi, jenis-jenis unggulan tanaman pengisi, dan mampu mengevaluasi tanaman kopi dan keberhasilan tanaman pengisi.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi cuka (asam asetat) terhadap pertumbuhangulma pada persiapan lahan. Penelitian dilakukan di Politeknik Lampung, Lampung dari bulan Juli sampaidengan September 2011. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok Lengkapsatu faktor, yaitu : konsentrasi cuka dengan empat taraf : 0%, 5%, 10% dan 20% dengan empat ulangan. Hasilpenelitian menunjukkan bahwa (1) konsentrasi cuka 10% - 20% mampu mengendalikan pertumbuhan gulmasampai dengan 4 MSA, terlihat dari tertekannya bobot kering dan persentase penutupan gulma total. (2)konsentrasi cuka 10% - 20 % mampu mengendalikan pertumbuhan gulma daun lebar Asystasia gangética,sedangkan gulma daun lebar lain yaitu kacangan (LCC) dan Mikania micrantha mampu dikendalikan dengankonsentrasi 20% sampai dengan 4 MSA. (3) Gulma golongan rumput yaitu Digitaria longiflora tidak mampudikendalikan oleh cuka sampai 8 MSA.Kata kunci : Cuka (asam asetat), Konsentrasi, gulmaABSTRACTThe objective of this research was to think the effect concentrations of vinegar (acetic acid) on growth ofweeds at land preparation. The experiments conducted in Politeknik Lampung, Lampung from July toSeptember 2011. The research design was used Completely Randomized Design (CRD) with one factor, i.e :concentration of vinegar with four levels : 0, 5%, 10%, and 20% with four replications. The results showed that:(1) vinegar concentration of 10% - 20% are able to control weed growth to 4 MSA, seen from the suppression ofthe dry weight and percentage of total weeds. (2) vinegar concentration of 10% - 20% are able to control thegrowth of broad leaf weeds Asystasia gangética, while the other broad leaf weeds are nuts (LCC) and Mikaniamicrantha able to be controlled by the concentration of 20% up to 4 MSA. (3) Type of grass weed i.e Digitarialongiflora is not able to be controlled of vinegar to 8 MSA.Key words : Vinegar (Acetic acid), concentration, weeds

Abstract

Percobaan lapangan untuk mengetahui pengaruh ketebalan mulsa alang-alang dan pola tanamtumpangsari terhadap pertumbuhan gulma dan produksi tanaman. Waktu pelaksanaan percobaan dimulai daribulan Juli sampai dengan November 2010. Rancangan yang digunakan adalah Rancangan Petak Jalur dengandua faktor dan tiga ulangan. Faktor pertama adalah mulsa alang-alang, yaitu M0: Tanpa mulsa ; M1: Mulsaketebalan 5 cm M2: Mulsa ketebalan 10 cm, Faktor kedua adalah pola tanam tumpangsari yaitu: P1: 100% cabai+ 25% kubis bunga ; P2: 100% cabai + 50% kubis bunga ; P2: 100% cabai + 75% kubis bunga. Hasil penelitianmenunjukkan bahwa (1) Penggunaan mulsa alang-alang 5 dan 10 cm dengan tumpangsari cabai 100% + kubisbunga 50% dan 75% mampu menekan pertumbuhan gulma dan menghasilkan pertumbuhan tanaman tertinggi.(2) Perlakuan ketebalan mulsa alang-alang 10 cm dan tumpangsari cabai 100% + kubis bunga 50%menghasilkan produksi buah cabai dan kubis bunga tertinggi.Kata kunci: cabai, gulma, kubis bunga, mulsa alang-alang, tumpangsari.ABSTRACTThe field experiment to find out the effect thickness of reed mulch and the planting pattern intercroppingon the growth of weed and crop production.
