Abstract

Rice is the main commodity food support in Indonesian society. As a country with a large population, there are challenges to improve the efficiency and optimizing the utilization of land resources. The purpose of this study is to determine the use of lines were superior and spacing are effective in increasing productivity. The research was conducted at the experimental land Faculty of Agriculture, Sebelas Maret University, Mojolaban, Sukoharjo. The research using Randomized Completely Block Design. The first factor is the lines, local lines Inpari 10, hybrid rice lines Tiongkok 1683, 1606, and 358. The second factor is the plant spacing, 18 cm x 18 cm, 22 cm x 22 cm, and 26 cm x 26 cm. Data were analyzed using analysis of variance and if there is a significant followed by Duncan Multiple Range Test at 5% level. Hybrid rice lines 358 and spacing of 26 cm x 26 cm is a combination of treatments that have a higher level of productivity is 5.86 ton/ha.

Abstract

Kaempferia rotunda that long ago been used to treat gastrointestinal disorders and also treat cancer, has promising opportunities to cultivate. There are several obstacles in cultivation today. Plant propagation by in vitro can be one solution. Basic media and plant growth promoting substance usage is an important factor which has to be concerned. Research aiming to produce high quality seed and in large numbers. Research has been carried out in Tissue Culture Laboratory, Agriculture Faculty, Sebelas Maret University, Surakarta, during July 2014 to August 2015. This research was used MS (Murashige and Skoog) media with combination treatment of each IBA and BAP concentration of 0, 1, 2, 3, and 4 ppm. The number of shoots that appear on the explant is the main observation variables. The results showed IBA and BAP are likely to affect the appearance of buds as much as 2 pieces in each explant at 0 ppm IBA treatment.

Abstract

Rice is the main commodity in food support, especially in Indonesian society. As a country with a large population, there are challenges in collecting the food needs of the population, the challenge is to improve the efficiency and optimizing the utilization of land resources. The purpose of this study is to determine the use of varieties / lines were superior and spacing are effective in increasing productivity. The research was conducted at the experimental land Faculty of Agriculture, Sebelas Maret University, Mojolaban, Sukoharjo. The research using Randomized Completely Block Design with 2 factors, namely rice varieties factor and plant spacing. Data were analyzed using analysis of variance and if there is a significant followed by DMRT (Duncan Multiple Range Test) at 5% level. 6 Chinese rice lines and spacing of 26 cm x 26 cm is a combination of treatments that have a higher level of productivity is 4.79 ton-1ha.

Abstract

Research on the growth and oleanolic acid content of pearl grass (Hedyotis corymbosa) in experimentall field of Medicinal Plants and Traditional Medicines Research and Development Center (B2P2TOOT), Tanjungsari Village, Tegal Gede Village, Karanganyar and B2P2TOOT laboratory, Tawangmangu, Karanganyar. The research has been conducted in August to November 2017. The purpose of this research is to know the dosage of cow manure and liquid organic manure which has the most influence to the growth and the oleanolic acid content of pearl grass. The experiment was designed in a randomized complete block design with twelve treatments and three repication. The observed data  analyzed using  variance analysis  with 5% level then if there was a significant difference in the continued test with Duncan’s Multiple Range Test (DMRT). The results showed that the use of cow manure at doses of 0 kg-1m2, 4,6 kg-1m2, 6,1 kg-1m2 and 7,6 kg-1m2 did not give increase to all observation variables. The use of POC dose 0 ml-1liter, 5 ml-1liter and 10 ml-1liter did not give increase to all observation variables. All given treatments may show that oleanolic acid is present in pearl grasses.
