“…Following preliminary the acquisition of the appropriate permits from the local forest management unit, surveys were conducted to the study location's research plots and final sampling locations were set up in coordination with the authorities. Sampling plots for weeds were designed with the point intercept method, recording weeds with a height of more than 20cm (Firmansyah et al, 2020) within sampling plots measuring 100cm x 100cm (Kartawinata and Abdulhadi, 2016). Following species identification and quantification, all data acquired from sampling plots were aggregated by research plot.…”

Background. The province of Central Java, Indonesia, hosts various well-developed agroforestry systems. Objective. To explore the interaction of weed diversity on the diversity of soil arthropods, specifically in four stations based on distinct ecosystems, namely teak (Tectona grandis L.f.) based agroforestry, complex agroforestry, cajeput (Melaleuca cajuputi (L.) Powell.) based agroforestry, and teak monoculture. Methodology. Data was collected from February to June 2022 in Geyer District, Grobogan Regency, Central Java Province, Indonesia, using the point interception method for weed vegetation and the pitfall trap method for soil arthropods. Results. The results showed that the dominant species observed in the agroforestry and monoculture ecosystems differ. Cynodon dactylon L.Pers. is the most dominant weed in all three agroforestry ecosystems, while Imperata cylindrica Beauv is the most dominant in teak monoculture. Oecophylla smaragdina F., an ant species locally known as rangrang, was the most dominant insect at all four stations. The Poaceae family was shown to be the most prevalent weed species on all stations. However, the agroforestry system displayed a greater variety of arthropods. Implications. The results of this study indicate that in agroforestry systems, the diversity, distribution, and density of soil-based arthropods are intimately related to the specific weed species that have evolved mutually beneficial interactions. Conclusion. This phenomenon demonstrates the intricate interplay between different species and the interspecies affinity within the community.

“…Jenis gulma yang dominan yang tumbuh di semua perlakuan yaitu Eleusine indica L. Hal ini menunjukkan bahwa gulma rumputan relatif dominan selama penelitian. Eleusine indica L memiliki biji yang banyak dan ringan sehingga mudah dibawa angin, serta tingkat penyebaran yang cepat sehingga cepat mendominasi dan dapat tumbuh diberbagai jenis tanah (Firmansyah et al, 2020 Mendasarkan pada indeks keragaman (H') pada minggu ke-2, 8 dan 12 setelah tanam, gulma yang tumbuh pada kedelai tumpangsari dan kedelai monokultur mempunyai nilai indeks keragaman antara 1,18-2,60 (Tabel 4), yang termasuk dalam kategori sedang. Semakin tinggi nilai H', semakin tinggi tingkat keanekaragaman gulma yang tumbuh (Magurran, 1988)…”

Soybean is an important food crop for Indonesia after rice and corn. Soybean productivity in Indonesia is still low because most farmers use monoculture cropping patterns which has many weaknesses. Intercropping is an alternative to increase soybean productivity because it has many advantages. Soybeans can be intercropped with corn because the two plants have different physical characteristics, physiology and growth patterns. This research aimed to obtain information about the diversity and abundance of weeds in soybean and corn intercropping. The study was conducted using a single factor treatment design which will be arranged in a single plot field design, using Grobogan variety soybean and Bisma variety corn. The treatment was the proportion of soybean and corn populations which consisted of 4 proportions, i.e. 2:1, 3:1, 4:1, and 5:1, and monoculture soybeans were also planted as a control. Observations on weeds were carried out at the age of 2, 8, and 12 weeks after planting (before harvest) with vegetation analysis. The size of each sample is 0.5 m x 0.5 m with 15 sample plots/plots. The results showed that based on the summed dominance ratio (SDR) in the research area, 16 species of weeds were dominated by broadleaf weeds, with the dominant types of weeds being Phyllanthus urinaria L., Eleusine indica L., and Oryza sativa L. The results showed that based on the Summed Dominance Ratio (SDR) in soybean there were 16 species of weeds that were dominated by broadleaf weeds, with the dominant types of weeds being Phyllanthus urinaria L., Eleusine indica L., and Oryza. sativa L. Weeds growing on soybean intercropping with corn and soybean monoculture have a medium diversity index (H').

“…Menurut Shiferaw et al (2018), adanya konversi suatu kawasan dapat mengganggu keseimbangan ekosistem. Menurut Firmansyah et al (2020), aktivitas manusia yang melakukan perubahan tata guna lahan dapat menyediakan ruang kosong, sehingga lahan tersebut dapat diinvasi oleh IAP yang memiliki kemampuan beradaptasi tinggi dan pertumbuhan sangat cepat.…”

Ketersediaan lahan rawa yang luas menyebabkan banyak lahan rawa dimanfaatkan sebagai pengembangan lahan pertanian. Seperti pada kawasan rawa Jembatan Kerinduan Kota Sungai Penuh, Provinsi Jambi memiliki beberapa tipe pemanfaatan ekosistem rawa seperti sebagai lahan pertanian dan lokasi wisata alam yang berpotensi memfasilitasi masuknya tumbuhan asing invasif. Tujuan dari penelitian ini adalah untuk mengetahui komposisi dan struktur tumbuhan asing invasif di kawasan rawa Jembatan Kerinduan Kota Sungai Penuh, Provinsi Jambi. Penelitian dilakukan pada bulan Desember 2020 hingga Maret 2021 dengan metode observasi di lapangan. Penentuan stasiun penelitian dilakukan secara purposive sampling dan diletakan satu transek pada setiap stasiun penelitian. Pada setiap transek terdapat 5 plot penelitian yang berukuran 5x5 untuk tingkat pertumbuhan pancang dan 2x2 untuk tingkat pertumbuhan semai. Hasil dari penelitian didapatkan 13 spesies IAP dari 10 famili dengan tipe habitus herba, tumbuhan air, semak, dan perdu. Persicaria attenuata memiliki nilai penting tertinggi yaitu 73,25% Nilai indeks keanekaragaman IAP tertinggi di kawasan rawa Jembatan Kerinduan Kota Sungai Penuh berada pada kawasan rawa yang telah dikonversi menjadi lahan sawah dengan tingkat keanekaragaman sedang (H’=1.78).
