Abstract

Cyperus rotundus L. and Ageratum conyzoides L. are commonly found in tomato field as weeds species. Weed compete with the crop for nutrient, water and light. In addition, weed released allelopathy that inhibited the growth of crop. The aim of this study was to compare the ability of allelopathy from C. rotundus L. and Ageratum conyzoides L. root extract to inhibit tomato plant growth. The study was conducted in Completey Randomized Design with two factors. The first factor was root extract from either C. rotundus L. and A. conyzoides L. as allelopathy. The second factor was concentration of root extract from both weeds (100, 300 and 500 g/ml). Each treatment combination was repeated four times. The results showed that A. conyzoides L. root extract had higher inhibition to growth of tomato plant than C. rotundus L. root extract. Increasing root extract concentration from both weeds increased inhibition of tomato plant growth.

Abstract

The research of biogas aims to obtain an alternative energy source which might replace fossil energy in the future. It was carried out starting from November 2017 to February 2018 in which was located in Langaleso Village, Dolo Subdistrict, Sigi District and in the Laboratory of Biotechnology, Department of Biology, Faculty of Mathematics and Natural Sciences, Tadulako University. The primary substrates were cow dung, chicken manure and the tofu liquid waste by cow rumen as inoculum. The installation of gas-flowed pipes was conducted by using paralon pipes with size ½ dan ¾ inch with the total lenght 8,40 m. The incubation period of the primary substrates was 30 days where the biogas volume quantification was periodically performed in the day of 10, 20, and 30. The results showed that biogas was formed at the incubation day of 10 which hence increase up to the day of 30. The observed gas volume was 223,568 cm3, 368,950 cm3 dan 458,302 cm3 respectively. The results of flame test representing blue flame indicated that the formed biogas contained the content of methane which higher than 70%. This hence revealed that the installation of biogas reactor with the type of ?fixed domed plant? equipped by ?watertrap? was able to produce a good quality biogas from the primary substrates were cow dung, chicken manure and the tofu liquid waste by cow rumen as inoculum for the application in the household scale.

Abstract

Different elevation of lands can affect environmental conditions such as light intensity, temperature, and humidity. The environmental conditions will affect the growth and species of weeds. The aim of this study was to compare the diversity and species composition of weed comunities on highland and lowland of cacao plantation.  The study was conducted by colecting the weed species from 25 plots with a size of 2 x 2 m. Every plot was placed by purposive sampling. The result showed that there were 26 species of weeds on highland while only 15 species of weeds were found on lowland. Weeds on highland was dominated by Ageratum conyzoides with  important value index (IVI) of 62.07% while on lowland was dominated by Euphorbia hirta with IVI of 26.56%. The weeds community has a medium diversity index while the value of Similarity Index (IS) was low (4.87%) between weeds community on highland and lowland. It could be concluded that different environmental condition would affect the number  and species of weeds.
