Abstract

One of the efforts to control weeds in preparing land for lowland rice cultivation with the No-Tillage system one of which uses isopropylamineglyphosate herbicide. The purpose of this study was to determine the dose of glyphosate herbicide that effectively controls weeds for preparation of lowland rice planting with the no tillage system, to determine changes in weed composition in lowland rice after the application of glyphosate herbicide, and to determine the effect of the no tillage system after the application of glyphosate herbicide on growth and paddy yields. Data collection was carried out from June to September 2022 in the rice fields of Trimurjo District, Central Lampung Regency and the Weed Science Laboratory, Faculty of Agriculture, University of Lampung. The treatment was arranged using a randomized block design with 4 replications and 6 treatments consisting of the glyphosate herbicide doses (1,080; 1,440; 1,800; 2,160 g/ha) + no tillage, manual weeding, and intensive tillage system. Homogeneity of variance was tested by Barlett's test and then analyzed for variance. Separation of the mean was carried out using the least significant difference test (LSD) at the 5% level. The results showed that the herbicide isopropylamine glyphosate doses of 1,800 and 2,160 g/ha of the no tillage system could be used to replace the intensive tillage system because it was effective in controlling total weeds, sedges, grasses, and broad leaf groups, dominant weed Fimbristylis miliacea, Echinochloa colonum, Ludwigia octovalvis and Monochoria vaginalis up to 6 WAP, causing a change in the composition of weed species from Echinochloa colonum become monochoria vaginalis at 3 WAP, and from Echinochloa colonum become Ludwigia octovalvis at 6 WAP. The growth  is not stunted and yield of lowland rice plants is equivalent to the intensive tillage system with grain yields per hectare of 5.14 - 5.49 t/ha. Key words : weeds, isopropylamine glyphosate, paddy field, no tillage

Abstract

The presence of bobontengan weed (Leptochloa chinensis) in rice fields is considered to be detrimental and need to be controlled. Compounds secondary metabolites plant can be used as herbicides for weed control. Cacabean (Ludwigia hyssopifolia) is one of the plants that contain secondary metabolites compounds. This study aimed to determine the potency of the extract of each part of cacabean plant and the level of concentration in germination and growth of bobontengan. The research was carried out from February to March 2023, in the Integrated Field Greenhouse, Faculty of Agriculture, University of Lampung. The research design used a Randomized Block Experiment Design (RAK). The treatment consisted of two factors with four groups. The first factor was the source of cacabean extract: leaves, stems and roots, while the second factor was the concentration of cacabean extract which consisted of 4 levels: 0, 5, 10 and 15%. The homogeneity of variance was tested by Bartlett's test and the additiveness of the data was tested by Tukey's test. If the assumptions are met, the data is analyzed by analysis of variance and differences in treatment mean values followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that extracts of leaves, stems and roots of cacabean at concentrations of 5, 10 and 15% effectively suppressed seed germination and bobontengan weed growth. L.hyssopifolia leaf extract was most effective in suppressing germination, shoot height growth, and dry weight of bobontengan weed. Cacabean leaves and stem extracts were most effective in suppressing the percentage of germination, shoot height growth, and the total dry weight of bobontengan. Concentration of 15% of Cacabean extract was most effective in suppressing the growth of shoot height of 2 MSA, root length, and dry weight of bobontengan, while the concentration of 10-15% was most effective in suppressing the percentage of germination and shoot height of 4 MSA. Sources of cacabean leaves, stem and root extracts were influenced by the level of extract concentration in suppressing seed germination and crown height.

Abstract

Jenis sayuran yang banyak diminati karena memiliki waktu tanam cukup singkat yaitu Pakcoy (Brassica rapa subsp. Chinensis). Kandungan gizi yang terdapat dalam pakcoy dan bermanfaat bagi kesehatan membuat pakcoy digemari oleh masyarakat. Hal tersebut dapat menjadi peluang bisnis bagi para petani karena pakcoy memiliki permintaan pasar tinggi dan budidaya yang cukup singkat. Kegiatan budidaya yang belum tepat terutama pada iklim mikro dan pemupukan menjadi salah satu penyebab terjadinya penurunan produksi pakcoy. Dalam meningkatkan produktifitas pakcoy dapat dilakukan dengan pengendalian gulma dan memperbaiki iklim mikro melalui aplikasi mulsa organik serta pemupukan melalui aplikasi pupuk. Tujuan dari dilakukannya penelitian ini untuk mengetahui penggunaan jenis mulsa dan pupuk serta interaksi antar keduanya berpengaruh terhadap pertumbuhan gulma dan tanaman serta produksi pakcoy. Penelitian dilaksanakan pada bulan Januari-April 2023 di Laboratorium Lapang Terpadu (LTPD), Universitas Lampung. Penelitian ini dirancang dalam Rancangan Acak Kelompok (RAK) faktorial yang terdiri dari dua faktor yaitu pemberian mulsa (B0, B1, B2) dan pemberian pupuk (P0, P1, P2) dan diulang sebanyak sebanyak tiga kali dengan total sebanyak 27 satuan percobaan. Data hasil penelitian dilakukan uji homogenitas yang diuji dengan uji Barlett dan uji Aditivitas data dengan dilakukan uji Tukey. Bila asumsi terpenuhi, data dianalisis dengan analisis ragam dan uji Beda Nyata Terkecil (BNT) 5%. Hasil penelitian menunjukkan bahwa penggunaan jenis mulsa alang-alang pada 4 MST dan interaksi mulsa alang-alang dengan pupuk kandang ayam pada 6 MST mampu menekan pertumbuhan gulma. Sedangkan, penggunaan kombinasi pupuk urea dengan pupuk kandang ayam meningkatkan produksi bobot segar tanaman. Sementara itu, jenis gulma yang mendominasi dalam penggunaan jenis mulsa dan jenis pupuk yaitu Cleome rutidosperma, Cyperus kyllingia, Euphorbia hirta, dan. Richardia scabra.

Abstract

Provinsi Lampung, sebagai salah satu penghasil kopi terbesar di Indonesia, menghadapi tantangan serius terkait rendahnya produktivitas kopi. Dengan rata-rata produksi hanya mencapai 0,75 ton per hektar, jauh di bawah potensi genetiknya yang mencapai 4 ton per hektar, sejumlah masalah budidaya menjadi penyebab utama rendahnya hasil panen. Salah satu masalah yang signifikan adalah kurangnya pemupukan tanaman dan penggunaan pupuk yang kurang lengkap oleh para petani. Sentra kopi di Provinsi Lampung, seperti Kabupaten Lampung Barat dan Tanggamus, menunjukkan perbedaan signifikan dalam produktivitas kopi. Kabupaten Lampung Barat memiliki produktivitas kopi yang lebih tinggi, mencapai 1,07 ton per hektar, sementara Kabupaten Tanggamus hanya mencapai 0,8 ton per hektar. Oleh karena itu, meningkatkan produktivitas kopi di Kabupaten Tanggamus menjadi kunci untuk mengangkat produktivitas secara keseluruhan di Provinsi Lampung.Berdasarkan tingkat kesuburan tanah, khususnya di Kecamatan Sumber Rejo tergolong rendah sampai sangat rendah. Oleh sebab itu, dalam pelaksanaan budidaya kopi, sangat direkomendasikan untuk melaksanakan kegiatan pemupukan dengan memperhatikan Teknik pemupukan yang tepat, selain itu perlu ditambahkan pembenah tanah seperti pupuk organik dan biochar. Hasil dari pengabdian ini adalah bawha pelaksanaan pengabdian mampu meningkatkan pengetahuan petani terkait budidaya kopi dari 42,6% Menjadi 87,6%. Selain itu, petani juga mampu melaksanakan pembuatan pupuk organik padat secara mandiri mulai dari pemilihan bahan, pembuatan larutan dekomposer, pembuatan lapisan hingga pengecekan suhu kompos dengan baik dan benar. Pengabdian ini diharapkan dapat meningkatkan produktivitas tanaman kopi dan kesejahteraan petani sekitar.

Abstract

One of the obstacles in rubber plant cultivation is the presence of weeds. Weeds reduce the quantity and quality of yields, interfere with the maintenance and harvesting process, and become hosts for pests and plant diseases. This study aims to determine the diversity and dominance of weeds in smallholder rubber plantations. The research was conducted in two locations of smallholder rubber plantations in Juni-Juli 2023. The first location was in Natar, South Lampung and the second location was in Negeri Katon, Pesawaran. Sample selection was done by purposive sampling method with 4 replicates. The results showed that in the Natar location there were 13 weed species, while in the Negeri Katon location there were 14 weed species. Three weed species that dominated in the two locations were Axonopus compressus, Asystasia gangetica, and Ottochloa nodosa. The A. compressus weed had the highest SDR in both locations at 20.23% in the Natar location and 18.79% in the Negeri Katon location. The results of this study can be used as a basis for determining appropriate weed control techniques.

Abstract

Testing of the control power of the paraquat dichloride herbicide in suppressing weed growth in immature coffee cultivation was carried out in Sumber Jaya, West Lampung in May-August 2023. The research aimed to obtain an effective dose of paraquat dichloride and determine its phytotoxicity to coffee plants. The treatments consisted of 5 levels of paraquat dichloride dosage, namely 276 g ha-1(B1); 414 g ha-1(B2); 552 g ha-1(B3); 690 g ha-1(B4); and 828 g ha-1(B5) and compared with manual weeding treatment (B6) and control (no treatment) (B7). The research used a Randomized Block Design (RBD) with 4 repetitions. Based on the research results, it can be seen that paraquat dichloride at a dose of 552 - 828 g ha-1 was effective in suppressing the total weed growth of the dominant weeds Asystasia gangetica, Ageratum conyzoides, Synedrella nodiflora, Ottochloa nodosa, Paspalum conjugatum, and Richardia brasiliensis until 8 days after application (DAA). Application of paraquat dichloride at a dose of 414 - 828 g ha-1 was able to control the growth of A. conyzoides and S. nodiflora weeds until 8 DAA. Application of paraquat dichloride at a dose of 276 - 828 g ha-1 on immature coffee plants did not cause symptoms of poisoning.
