Abstract
INDONESIA:
Gulma merupakan tanaman pengganggu bagi tanaman budidaya yang mengakibatkan penurunan terhadap hasil dan kualitas panen. Oleh karena itu, perlu dilakukan pengendalian gulma tersebut, namun tidak berdampak negatif terhadap lingkungan. Upaya pengendalian tersebut diduga dapat dilakukan dengan memanfaatkan senyawa alelokimia berupa tanin dan triterpenoid yang berasal dari daun rumput bambu (Lophaterum gracile). Penelitian ini bertujuan untuk mengetahui pengaruh herbisida nabati dari ekstrak daun rumput bambu terhadap pertumbuhan gulma E. crusgalli, A. conyzoides, dan C. rotundus dan untuk mengetahui konsentrasi yang sudah mampu dalam menghambat pertumbuhan gulma tersebut.
Penelitian ini dilakukan pada bulan Februari hingga Maret 2018 di Desa Talun Kecamatan Kayen Kabupaten Pati Jawa Tengah. Penelitian ini merupakan penelitian eksperimental dengan perlakuan berupa enam perlakuan yakni konsentrasi 0% (kontrol), 10%, 20%, 30%, 40%, dan 50% dan dilakukan dalam empat kali ulangan. Teknik analisis data dilakukan dengan deskriptif kualitatif. Variabel yang diukur berupa pertumbuhan gulma dengan parameter yang diamati adalah tinggi gulma, jumlah daun, berat basah, berat kering, uji fitotoksisitas, dan persentasi kematian.
Hasil penelitian ini menunjukkan adanya pengaruh terhadap pertumbuhan E. crusgalli, A. conyzoides, dan C. rotundus berdasarkan analisis deskriptif, yakni terjadi gangguan fisiologis dengan ditandai adanya pertumbuhan tidak normal, perubahan warna, baik pada daun maupun batang, selain itu terdapat matinya jaringan dengan ditandai mengeringnya pada bagian tubuh tumbuhan. Konsentrasi ekstrak daun rumput bambu (L. gracile) yang sudah mampu menghambat berat kering gulma E. crusgalli, A. conyzoides, dan C. rotundus pada konsentrasi 10% adalah 0,66 gram, 0,004 gram, dan 0,03 gram dibandingkan dengan kontrol 1,06 gram, 0,26 gram, dan 0,05 gram.
ENGLISH:
Weeds are disturber plants for cultivated plants that result in a decrease in yield and harvest quality. Therefore, it needs to control the weeds, but it has not a negative impact on the environment. The control may be carried out by utilizing alelochemical compounds such as tannins and triterpenoids that are derived from bamboo grass leaf (Lophaterum gracile). The research aims at determining the influence of vegetable herbicide of bamboo grass leaf extract (L. gracile) against weed growth of E. crusgalli, A. conyzoides, and C. rotundus and to know the concentrations that have been able in inhibiting the growth of the weeds.
The research had been conducted from February to March 2018 in Talun Village, Kayen District, Pati, Central Java. The research is experimental research with six treatment treatments, namely 0% concentration (control), 10%, 20%, 30%, 40%, and 50% and done in four replications. Data analysis technique was done by qualitative descriptive. The variables were measured by weed growth with observed parameters, namely weed height, leaf number, wet weight, dry weight, damage percentage, and death percentage.
The research results indicated an influence on the growth of E. crusgalli, A. conyzoides, and C. rotundus based on descriptive analysis, namely occurring the physiological disorder with abnormal growth, discoloration, both on the leaves and stems, also there was the death of the network that was marked by the dry on the body of the plant. The concentration of bamboo grass leaf extract (L. gracile) which has been able to inhibit the dry weight of E. crusgalli weeds, A. conyzoides, and C. rotundus at 10% concentration was 0.66 gram, 0.004 gram, and 0.03 gram which were compared with control of 1.06 grams, 0.26 grams, and 0.05 grams
