“…Oleh karena itu, diperlukan upaya nyata dalam meningkatkan pendidikan dan pelatihan petani agar mereka dapat mengadopsi metode pertanian yang lebih ramah lingkungan serta mengurangi dampak negatif terhadap lingkungan. Pemberian dosis pupuk kompos 10-40 ton/ha nyata berpengaruh terhadap tinggi tanaman, jumlah daun dan berat segar tanaman (Juniati, Baharuddin, & Ernita, 2023). Terdapat perbedaan pertumbuhan tinggi batang yang sangat nyata akibat pemberian pupuk kompos dengan dosis yang berbeda (Jailani, 2022).…”

The majority of residents in Punggur Kapuas are engaged in farming, primarily in horticulture and food crops, making agriculture a pivotal economic sector in the region. However, a significant issue has been the heavy reliance on chemical pesticides and fertilizers, which not only pose environmental risks but also indicate a lack of knowledge regarding sustainable and eco-friendly farming practices. The continuous use of chemical inputs has led to soil and water pollution, as well as disruptions to the natural ecosystem. To combat these challenges, this initiative focuses on training and educating farmers in the production of natural botanical pesticides and organic compost. The project encompasses needs analysis, collaborative design, outreach and training, monitoring, and financial analysis to compare the costs of natural alternatives with chemical inputs. The training component covers two main aspects: the production of botanical pesticides using readily available natural materials such as papaya leaves and garlic, and the creation of organic compost from organic waste. Compost production has a host of benefits, including improved soil fertility and reduced dependence on harmful chemical fertilizers. The method used is by counseling, discussion and direct practice in the field. The outcomes of this initiative include enhanced knowledge and skills among the farming community in Punggur Kapuas regarding the creation of safe and environmentally friendly botanical pesticides, a reduction in the use of chemical pesticides, increased productivity of organic crops, and heightened awareness of the importance of sustainable farming practices. The project has already demonstrated positive impacts, with participants gaining practical expertise in botanical pesticide and compost production. The initiative aims to encourage the adoption of organic farming practices and environmental sustainability, thereby benefiting the local economy and ecosystem. Future efforts may include extension activities, active mentoring, and supplementary skills training to further advance organic crop cultivation and promote sustainability in local agriculture.

“…Di Indonesia rendahnya produksi tanaman dipengaruhi oleh berbagai faktor salah satunya adalah kompetisi dengan gulma (Rakian et al, 2018). Penurunan hasil beberapa tanaman budi daya di lahan kering akibat gangguan gulma sangat tinggi antara lain kedelai 26-52% (Hendrival et al, 2014), padi gogo 26-35% (Touré et al, 2013), kacang tanah 72-89% (Erliyana et al, 2015), jagung 28-56% (Dinata et al, 2017), kacang hijau 54-75% (Mahendra et al, 2017).…”

“…Selain C. dactylon dan C. rotundus ada gulma dari golongan daun lebar yang memiliki dominansi kuat dibandingkan dengan gulma lainnya antara lain A. conyzoides, P. niruri, Euphorbia hirta, H. pseudocorymbosa, Amarathus spinosus, dan P. urinaria. Gulma tersebut merupakan gulma dominan yang tumbuh di lahan kering di Indonesia yang ditanami sawi (Hafsah et al, 2012), padi gogo (Touré et al, 2013), kedelai (Hendrival et al, 2014), kacang tanah (Erliyana et al, 2015), kacang hijau (Mahendra et al, 2017), dan jagung (Rahayu et al, 2019). Hasil penelitian lain menyatakan bahwa gulma golongan daun lebar memiliki dominansi lebih kuat pada pertanaman jagung dibandingkan golongan rumput dan teki (Suryaningsih et al, 2013;Oksari, 2017).…”

AbstrakGulma merupakan salah satu masalah utama dalam sistem budi daya tanaman, khususnya di lahan kering. Oleh karena itu, pengetahuan tentang pengolahan tanah di lahan kering dengan tanpa olah tanah akan memberikan informasi berguna dalam pengelolaan gulma. Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan gulma berdasarkan golongan dan spesies gulma, bobot kering gulma, dan rasio dominansi gulma pada lahan tanpa olah tanah (TOT) di lahan kering. Rancangan lapang yang digunakan adalah rancangan acak kelompok dengan tiga ulangan. Observasi dan pengambilan sampling dilakukan melalui pengamatan gulma pada waktu 0, 2, 4, 6, 8, dan 10 minggu. Komponen kelimpahan gulma yang diamati meliputi jumlah gulma, bobot kering gulma dan rasio dominansi gulma. Hasil penelitian menunjukkan bahwa gulma golongan daun lebar memiliki jumlah spesies tertinggi namun dengan dominasi yang setara dengan gulma golongan rumput. Cynodon dactylon merupakan spesies paling dominan yang tumbuh di lahan kering tanpa olah tanah yang konsisten di setiap waktu pengamatan dengan jumlah >500, nilai rasio dominansi gulma >10, dan bobot kering biomassa >12 g. Implikasi dari penelitian ini adalah mengetahui pola pertumbuhan gulma di lahan kering tanpa olah tanah dalam upaya pengendaliannya untuk kepentingan budi daya pertanian.Abstract Weeds are one of the main problems in cropping systems, especially on dry land. Therefore, the knowledge of soil tillage in dryland areas with no-till will provide svaluable information in weed management. The objective of this study was to determine the abundance of weeds based on weed types and species, weed dry weight, and summed dominance ratio in dryland conditions with no-till. The field design used was a randomized block design with three replications. Observation and sampling were conducted by observing weeds at a time of 0, 2, 4, 6, 8, and 10 weeks. Weed abundance components observed included the number of weeds, summed dominance ratio, and dry weight of weeds. The results showed that the broadleaf weeds had the highest number of species, but the dominance was equivalent to the grass weeds. Cynodon dactylon was the most dominant and consistent species that grew in dryland with no-till with the number of species >500, summed dominance ratio >10, and biomass dry weight >12 g at each observation time. The implication of this study was to know the pattern of weeds growing in dryland área with no-till to control weeds for cropping systems purposes.

“…Rendahnya hasil kacang tanah dapat juga disebabkan oleh kehadiran gulma. Terdapat interaksi antara jenis dan kerapatan gulma dalam mempengaruhi tinggi tanaman, bobot polong segar, bobot polong kering/petak dan bobot 100 butir kacang tanah (Erliyana et al, 2015). Gulma yang dibiarkan tumbuh pada tanaman kacang tanah dapat menurunkan hasil sampai dengan 50% (Moenandir, 1993).…”

[THE EFFECT OF PLANTING DISTANCE AND WEDDING FREQUENCY ON GROWTH, YIELD OF PEANUT (Arachis hypogaea L) AND WEED POPULATION]. This study was aimed to determine planting distance and frequency of weeding which gives the highest growth and yield of peanuts. Peanut plants were planted in the Experimental Field of the Faculty of Agriculture, Bengkulu University from October to December 2018. The study was arranged in a Complete Randomized Block Design (RCBD) with 2 factors and 3 replications. The first factor is the planting distance of 40 cm x 20 cm; 40 cm x 30 cm and 40 cm x 40 cm. The second factor is the frequency of weeding consisting of no weeding, 1x weeding (age 2 WAP), 2x weeding (2 and 4 WAP), and 3x weeding (2, 4, and 6 WAP). The results showed that the interaction between the spacing of 40 cm x 40 cm and 2 x weeding can increase plant height. The spacing of 40 cm x 40 cm can reduce the population and dry weight of broadleaf weeds. The planting distance of 40 cm x 30 cm can increase the fresh weight of pods, pod weight/plot, and the highest dry weight of pods/plants. The frequency of weeding 2x can reduce the population and dry weight of broadleaf weeds; whereas weeding frequency 3x can reduce weed populations of grass and sedges- weeds, and dry weight of broadleaf weeds. The 3x weeding frequency can also increase the total number of pods/plants, pod weight/plot, and pod weight/plant.
