Oyong production is still low due to the limited availability of quality seeds. The production can be increased by one of the plant breeding techniques, which is mutation technique. The technique of mutation by chemical mutagens is able to increase the genetic diversity ofplants allowing the breeding to select genotype of plants in accordance with the intended breeding objective. Therefore, research is required to be conducted by using colchicin as a chemical mutagen which causes polyploid, in which organism has three sets or more chromosomes inside its cells. Meanwhile, the general nature of this polyploid plant is being sturdier; parts of the plantare bigger; so that later, its poor nature will be better as well as changing the potency of the result. Research using complete randomized block design (RBD) with one factor concentration of 0,1% (P1), 0,2% (P2), 0,3% (P3), 0,4% (P4), 0,5% ( P5), and 0,6% (P6). Colchicines treatment can cause changes in growth and yield variables. Colchicines treatment with a concentration of 0,3% showed positive changes to theweight of fruit, fruit diameter and length of the fruit. An increase in diversity on growth and yield components especially on colchicines treatment with 0,3%concentration.

Banana is one of the favorite tropical fruit. Banana business development begins with the provision of quality seeds. Tissue culture is a seed propagation technology that can produce large amounts of seed and a relatively short time by utilizing limited plant material. The planlets result of tissue culture needs to be acclimatization before planted in the field. Hydroponic substrate-based acclimatization is expected to produce seeds that are free from soil pathogens. Adjustment of the concentration of nutrients is important in order to produce a growth response that significantly affects and does not cause poisoning or plasmolysis. This study aims to determine whether hydroponic substrate types and nutrient concentrations affect the growth of Raja Bulu Kuning Banana plantlets. The experiment was carried out at net house, Faculty of Agriculture, Universitas Sebelas Maret Surakarta in October 2016 - January 2017. The treatment factors were substrate types (bagasse, arenga peat, steamed husk) and concentration of the nutrient solution (equivalent to EC 1.8, EC 2.0, and EC 2.5 mScm-1). The result showed that steamed husk is the best as the hydroponic substrate, while nutrient solution concentration equivalent to EC 1.8 mScm-1 is sufficient for acclimatization of Banana plantlets cv.Raja Bulu Kuning.

This study aims to determine the effect of the bamboo ash and straw compost on brown planthopper and rice production. This research was conducted in Bakaran, Sukosari Village, Jumantono, Karanganyar in 12ndDecemberMarch 2017. The study was conducted using Complete Randomized Block Design (RCBD) in paddy fields consisting of 16 plots, each was 16 m2 with Bamboo Leaftreatment, Straw Compost, and Chemical Silica with SiO2of 200 kg-1ha dosage. The variables observed were: Population of brown planthopper, stem hardness, plant height, number of tillers, number of productive tillers, weight of 100 seeds, weight of filled seed, hollow seed weight and percentage of hollow seeds. The data obtained were analyzed by Analysis of Variance (ANOVA) and if there was a significant difference, it followed by Duncans Multiple Range Test (DMRT) at 5% level. The results showed that bamboo leaf ash and straw compost not significan increase the hardness of the rice plant stems and brown planthopper population. Straw compost has the highest potential compared to other treatments because it produces the hardest stem rice and the lowest brown planthoppers population at 11 Weeks. The application of silica from various sources has no direct role in rice production.
