Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk memberikan pemahaman dan keterampilan kepada masyarakat Desa Alue Piet, Kecamatan Panga, Kabupaten Aceh Jaya, dalam memanfaatkan sumber daya lokal untuk mengendalikan hama dan penyakit tanaman secara alami. Fokus utama kegiatan ini adalah proses pembuatan pestisida nabati dari daun mimba sebagai solusi pestisida nabati yang aman dan ramah lingkungan dalam menjaga keberlanjutan pertanian di wilayah tersebut. Kegiatan dimulai dengan sosialisasi mengenai pentingnya pengendalian hama yang berkelanjutan dan dampak negatif penggunaan pestisida kimia. Selanjutnya, melibatkan partisipasi aktif masyarakat dalam mengumpulkan dan mengidentifikasi daun mimba sebagai bahan utama. Proses ekstraksi senyawa aktif dari daun mimba juga diajarkan kepada masyarakat, bersama dengan teknik formulasi dan aplikasi pestisida nabati yang dihasilkan. Hasil kegiatan ini mencakup peningkatan pengetahuan masyarakat mengenai pengendalian hama tanaman secara alami, serta pemberdayaan mereka dalam memproduksi dan menggunakan pestisida nabati dari daun mimba. Kegiatan pengabdian masyarakat ini diharapkan dapat memberikan kontribusi positif dalam mendorong penerapan praktik pertanian yang berkelanjutan dan berdaya tahan di Desa Alue Piet, serta memberikan inspirasi bagi masyarakat sekitar untuk mengadopsi pendekatan serupa dalam pengelolaan pertanian mereka.

Abstract

Weed management is essential in soybean cultivation. Among the most widely practiced methods is chemical weed control using herbicides, as it is considered more effective and efficient in terms of cost, time, and labor requirements. This study aims to identify the optimal dose of flumioxazin herbicide that can effectively suppress weed growth while enhancing the growth and yield of soybean plants. This study was conducted from August to November 2024 at the Experimental Farm of the Faculty of Agriculture, Universitas Gunung Leuser, Kutacane, Southeast Aceh Regency, Aceh Province. The experiment was arranged in a non-factorial Randomized Complete Block Design (RCBD) with three replications. The treatment factor was the dose of flumioxazin herbicide, consisting of four levels: D0 = 0 g a.i ha-1, D1 = 400 g a.i ha-1, D2 = 800 g a.i ha-1, and D3 = 1200 g a.i ha-1. The observed variables included weed control percentage, weed cover, weed fresh weight, plant height, number of leaves, number of seeds per plant, and dry seed yield of soybean. The agronomic practices included the application of flumioxazin herbicide at one day after sowing (DAS) according to the respective treatment doses. The application of flumioxazin herbicide at a dose of 400 g a.i ha-1 was effective in increasing weed control percentage, reducing weed cover, and decreasing weed biomass in soybean cultivation. However, higher herbicide doses induced phytotoxic effects on soybean plants. As a result, flumioxazin application did not significantly improve plant height, number of leaves, seed number, or dry seed yield.

Abstract

Weed management is commonly achieved through herbicide application; however, excessive herbicide use may lead to weed resistance and environmental degradation. This study aimed to determine the effective dose of organic siam weed (Chromolaena odorata L King and Robinson) mulch for suppressing weeds and improving soybean growth and yield. The experiment was conducted in Lawe Sagu Hulu Village, Lawe Bulan Subdistrict, Aceh Tenggara Regency, Aceh Province, from August to December 2024. A non-factorial randomized complete block design was used with five mulch doses: 0, 4.8, 9.6, 14.4, and 19.2 t ha-1, each replicated four times. Experimental plots 2.5 × 2.5 m were prepared through standard tillage, and chopped siam weed mulch 10 cm was applied to the soil surface at planting according to treatments. Observed variables included root and plant fresh weight, weed control percentage, weed species number, weed fresh weight, seed weight, and 100-seed weight. Data were analyzed using SPSS version 16, and significant effects were further tested with Duncan’s New Multiple Range Test. Application of 4.8 t ha-1 mulch improved weed control percentage, while higher doses of 14.4–19.2 t ha-1 effectively reduced weed species number and weed fresh weight at 30 days after treatment, as well as increased root fresh weight at 40 days and soybean fresh weight at 20 and 40 days after treatment.
