Chryssanthenum is ornamental plant with variety of shape and color which are unique and appealing. So that, it is in great demand in the community. The production of Chrissanthenum conventionally hampered by availability and quality of seeds. Thus, it needs research through tissue culture. The aim of this research is to know interaction between coconut water and thiamine and to determine the best coconut water and thiamine concentration toward Chryssanthenum micro cuttings. This research used laboratory experimental method by using completely randomized design with two factor. The 1st factor was coconut water concentration consisted of three level which were 5%, 10% and 15%. The 2nd factor was thiamine concentration consisted of three level which were 1mg/L, 2 mg/L and 3 mg/L. From the two factors, those were found that, there were nine combination of treatments and repeated 3 times. The variety of data was analyzed by using Analysis of Variance (ANOVA) with level of α=5%, and continued by examining Duncan’s Multiple Range Test (DMRT) with level of α=5%. The result indicated that the interaction of coconut water concentration was 5% and thiamine was 1 mg/L on the parameters when growing shoot. There was also interaction on coconut water concentration which was 10 % and thiamine was 1 mg/L on the parameters in the number of shoots. interaction of coconut water combination was 15% and thiamine was 2 mg/L on fresh weight. The addition of 10% coconut water and 1 mg/L thiamine showed the best result on shoot length.
Sunan Candlenut (Reutealis trisperma (Blanco) Airy Shaw) is a type of vegetable oil producing plant that has great potential as a source of raw material for biodiesel. To develop Sunan Candlenut plants on marginal land, it is necessary to achieve innovation in their cultivation, specifically by providing NPK fertilizer and nutrition with plant supplements using chitosan. In an effort to increase the effect of chitosan on plant growth, it is necessary to add gibberellins (GA3). There was no interaction between NPK fertilizer application at various doses and chitosan administration on all vegetative growth parameters of the Sunan Candlenut plants which were observed. The results showed that the dose of NPK fertilizer had the same effect on all parameters. Chitosan plus (chitosan 30 ml/l + GA3) gives a better effect on all parameters observed. Plants treated with chitosan had a higher number of secondary branches and leaf canopy width than those without chitosan.
This research is a preliminary study of planting ornamental plants with a green wall system. This study aims to provide an overview and information about the selection of types of plants that are suitable and commonly used in making green walls and arranging selected plants in green walls system. Green wall system which is often called vertical garden is a technique to plant ornamental plants, vegetables or other types of plants with a free design that considers various resources that allow plants to grow vertically. The advantages of green walls are efficient use of soil, beautifying the environment, adding location value, cleaning the air, lowering temperature, producing oxygen and providing fresh food that is close to the surrounding environment at home. Not all types of plants can be planted vertically. Easy-to-grow plants, short appearance and slow growth are common characteristics used for green walls. The special characters of the selected plants are determined based on the group of indoor or outdoor plants. Consideration of nutritional, light, water and plant requirements will determine the success of planting and the sustainability of vertical planting.
This research aims to find out the influence of toping on each melon tree towards the yield of melon, and the influence of the use of various growing media compositions towards the yield of melon. This research is conducted in green house at Kaliurang Street km 16.3, Umbulmartani, Pakem, Sleman Regency, the Special Region of Yogyakarta. The research was held when august to October 2017. The research method used is Field Trial which is arranged by using Complete Randomized Design with two treatment factors and is repeated three times. The first factor is the use of growing media in the form of husk charcoal and zeolite (100% : 0%), (85% : 15 %), (70% : 30%), and (55% : 45%). The second factors are performing toping and not performing toping. Based on the analysis, it is shown that there is no interaction between growing media composition and toping treatment based on growing parameters or yield. The growing media composition with husk charcoal and zeolite (85% : 15%) shows a good result in affecting the parameters of fruit weight and fruit diameter. Toping treatment gives a good result for the parameters of fruit weigh, fruit diameter, brix, and flesh thickness.Keywords: melon, toping, growing media composition, hydroponic drip system
