The objectives of this research were to find out the efficacy of metsulfuron methyl herbicide to weeds of unproductive yet oil palm, to find out the growing weeds composition change after application, and to findout the influence. This research was conducted in randomizedgroup design with 8 treatments of metsulfuron methyl dosages of 15, 20, 25, 40, and 50 h.ha-1, mechanical weeds removal, with control, and 4 repetitions. Variance homogeneity was tested with Bartlett test and data addition was tested with Tukey test. Differences in median tested using Least Significant Differenc (LSD) level 5%. The results showed that: (1) 15 to 50g.ha-1 metsulfuron methyl dosages were effective to oppress total weed scovering, total weeds toxicity anwide leaf weeds dry weight12 weeks after application (WAA), grass type weeds dry weight at particular dosages to 4 (WAA) and dry weight of dominant weeds including Cynodon dactylon, Commelina benghalensis and Centro semapubescens; (2) various dosages to test caused composition changes of weeds types in observation 2 to 12 (WAA); (3) weeds controlling in various dosages to test did not poison leafs and roots of unproductive yet oil palm. Keywords: Metsulfuron methyl, weeds, unproductive yet oil palm.

The abundance of weeds in cultivated land can directly inhibit competition of plants growth. Weed control using bioherbicides is one of eco-friendly alternative. This research aims to determine the bioherbicide formulation of lerak fruit extract with the addition of adjuvants which can inhibit the germination of Ludwigia octovalvis. The research was conducted at the Weed Laboratory of the Faculty of Agriculture, University of Lampung in December 2019 - March 2020. The researcher used Complete Randomized Design (CRD) with four replications.Â The research treatments consisted of lerak fruit extract + KAO adjuvant, lerak fruit extract + VCO, lerak fruit extract + Tween, pure lerak fruit extract, and control (aquades).Â The results showed that the application of 50% (500 g / l) lerak fruit extract with the addition of VCO, KAO, and Tween adjuvants at a concentration of 2% (20 ml/l) was able to inhibit weed germination Ludwigia octovalvis by 95%-100%. The application of lerak fruit extract with the addition of a 2% concentration of VCO adjuvant was the most effective in inhibiting weed germination Ludwigia octovalvis.Â Keywords : adjuvants, Bioherbicide, Sapindus rarak, Ludwigia octovalvis, weed

Adjuvant is an ingredient added in a formulation to increase the effectiveness of lerak fruit in inhibiting weeds. This study aims to determine the type of adjuvant in lerak fruit extract that can increase the inhibition of germination of Fimbristylis miliacea and to determine the type of adjuvant in lerak fruit extract that is most effective in inhibiting the germination of F. miliacea. The research was conducted from December 2019 to March 2020 in the Weed Laboratory, Faculty of Agriculture, University of Lampung. This study used a Completely Randomized Design (CRD) to determine the type of adjuvant given to lerak fruit extract on F. miliacea germination with 4 replications. The treatments consisted of lerak fruit extract, lerak fruit extract + VCO adjuvant, lerak fruit extract + KAO adjuvant, lerak fruit extract + Polysorbate 80 adjuvant, and control. The Bartlett test was used to test the homogeneity of variance, if the assumptions of the analysis of variance were met, then the mean value of the treatment was continued with the Least Significant Difference (LSD) test at the 5% level. The results showed that adjuvants and without adjuvants added to lerak fruit extract at a concentration of 50% (500 g/l) were able to suppress the percentage of germination and the speed of germination of Fimbristylis miliace seeds.Keywords: adjuvants, lerak fruit extract, Fimbristylis miliacea, weed

The oil palm plant which has the Latin name Elaeis guineensis Jacq. is one of the main plantation commodities in Indonesia. The growth of weeds on oil palm cultivation land causes competition for growth facilities and affects the growth of oil palm plants (TBM). One of the active ingredients of herbicides used to control weeds in TBM oil palm plantations is metsulfuron methyl herbicide. This study aims to determine the effective dose of 20% metsulfuron methyl herbicide in suppressing weed growth in TBM oil palm plants, to determine changes in the composition of weed species that grow after the application of metsulfuron methyl herbicide, to determine the effect of phytotoxicity on TBM oil palm plants due to herbicide application. This research was conducted in an oil palm plantation in Braja Lebah Village, Braja Selebah District, East Lampung Regency and the Laboratory of Weed Science, Faculty of Agriculture, University of Lampung from August to December 2022. This study used a Randomized Block Design (RAK) with 6 treatments 6 and 4 replications with metsulfuron methyl dose as follows 15; 20; 25; 30g/ha; mechanical weeding and control. The homogeneity of the variance of the data was tested by Barlett's test and the additivity of the data was tested by using the Tukey test and the difference in the mean treatment was tested by the Least Significant Difference (LSD) test at the 5% level. The research results show that; (1) The herbicide methyl metsulfuron 20% at a dose of 15 – 30 g/ha is effective in controlling the growth of total weeds, the dominant weeds Asystasia gangetica and Praxelis climatidea, Boreria alata, Melastoma malabathricum and Richardia brasiliensis up to 12 MSA; (2) Metsulfuron Methyl Herbicide 20% at a dose of 15 – 30 g/ha caused a change in weed composition at 4, 8, and 12 MSA; (3) The application of 20% metsulfuron methyl herbicide at a dose of 15–30 g/ha does not cause poisoning in TBM oil palm plants.

Weeds are plants whose existence is not expected by farmers because they interfere with cultivated plants. But there are weeds that can produce phenolic compounds such as Clidemia hirta L which can be used as bioherbicides. This study aims to determine the effect of Clidemia hirta L. leaf extract on the germination and growth of Praxelis clematidea weeds. The research was carried out from June 2021 to September 2021 at the Weed Science Laboratory and Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. This study used a completely randomized design (CRD) method with 6 treatments with concentrations of Clidemia hirta L leaf extract, namely 0; 1.5; 3.0; 4.5; 6.0; and 7.5%. Each treatment was repeated 6 times to obtain 72 experimental units. The observed variables are germination, crown height, root length, dry weight, and weed poisoning level. The data obtained were analyzed by analysis of variance and continued with the Least Significant Difference Test (LSD) at the 5% level. The results showed that the germination of Praxelis clematidea weed was significantly inhibited by the treatment of Clidemia hirta L leaf extract with a concentration of 1.5; 3.0; 4.5; 6.0; and 7.5%. While concentrations of 3.0%, 4.5%, 6.0%, and 7.5% Clidemia hirta L. leaf extract inhibited the growth of Praxelis clematidea weeds in the greenhouse.
