The growth of weeds in immature cocoa plants is highly susceptible to competition for water, nutrients, and light, which can disrupt the growth of cocoa plants. Efforts to manage cocoa cultivation include weed control using the chemical herbicide paraquat dichloride, a non-selective contact herbicide. This study aimed to determine the effective dosage of paraquat dichloride for controlling weeds in immature cocoa plants, changes in weed composition, and phytotoxicity on immature cocoa plants following the application of paraquat dichloride. The study was conducted in Talang Sepuh Village, Talang Padang Sub-district, Tanggamus Regency, from March–May 2024. The research employed a Randomized Complete Block Design (RCBD) with six treatments and four replications. Treatments included paraquat dichloride at doses of 414 g/ha, 552 g/ha, 690 g/ha, 828 g/ha, mechanical weeding, and a control group (no weed control). Data variance homogeneity was tested using Bartlett's test, and data additivity was evaluated with Tukey's test. If the assumptions were met, the mean difference was analyzed using the Least Significant Difference (LSD) test at a 5% significance level. The results indicated that paraquat dichloride at doses of 414–828 g/ha effectively controlled total weeds, broadleaf weeds, and dominant weeds (Eleusine indica, Praxelis clematidea, and Synedrella nodiflora). Meanwhile, doses of 552–828 g/ha were effective in controlling grass weeds and dominant weeds (Ottochloa nodosa and Asystasia gangetica). The application of paraquat dichloride did not alter weed composition and did not cause phytotoxic effects on immature cocoa plants..Keywords : Herbicide, Paraquat dichloride, Weed, Immature cocoa.

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.

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.

This study aimed to evaluate the efficacy of single herbicides saflufenacil, trifludimoxazin, and their mixtures, as well as to determine the interaction characteristics of the saflufenacil and trifludimoxazin combination in weed control. The experiment was conducted in a Plastic House in Natar District, South Lampung Regency, from April to May 2025. A single-factor Randomized Block Design (RBD) was applied with 54 treatment combinations, consisting of 3 herbicide types at 6 dosage levels: single saflufenacil (0, 25, 50, 100, 200, and 400 g/ha), single trifludimoxazin (0, 12.5, 25, 50, 100, and 200 g/ha), and their mixtures (0, 37.5, 75, 150, 300, and 600 g/ha). Treatments were applied to 3 weed species: the broadleaf Ageratum conyzoides, the grass Digitaria ciliaris, and the sedge Cyperus kyllingia. Each treatment was replicated 6 times. The interaction analysis of herbicide mixtures was carried out using the Multiplicative Survival Model (MSM), since the two herbicides have different modes of action. The results showed that: (1) single saflufenacil was only effective in controlling Ageratum conyzoides at (25-400 g/ha). Single trifludimoxazin effectively controlled Ageratum conyzoides (12.5-200 g/ha), Digitaria ciliaris (200 g/ha), and Cyperus kyllingia (50-200 g/ha). The mixture of saflufenacil+trifludimoxazin effectively controlled Ageratum conyzoides (37.5-600 g/ha), Digitaria ciliaris (75-600 g/ha), and Cyperus kyllingia (300-600 g/ha). (2) With an expected LD50 value of 83.36, which was higher than the observed LD50 value of 67.33, a co-toxicity coefficient of 1.24 (>1) was obtained, indicating that the mixture exhibited a synergistic effect.
