The Effect of Addition of Ca(NO3)2 to the Results of Lettuce (Lactuca sativa L.) in the Hydroponic System of Deep Flow Technique (DFT). Plants, in general, require composition, concentration, and volume of nutrient solutions which different depends on the type and phase of plant growth. Leaf vegetable crops such as lettuce (Lactuca sativa L.) require higher Nitrogen (N) nutrients than other vegetable crops, but the problem we faced at the moment is the hydroponic nutrients that are traded only in the general form of nutrient, therefore the addition of N nutrients in the form of calcium nitrate (Ca(NO3)2) needs to be done to meet the needs of lettuce plants. This study was aimed to determine the effect of the addition of Ca(NO3)2 and to find the optimum dosage of the addition of Ca(NO3)2 to the general hydroponic nutrition of vegetables on lettuce use DFT hydroponic system. The treatments consisted of five levels which are nutrition AB Mix general vegetable as a control, and nutrition AB Mix with the addition of 30 g, 60 g, 90 g, and 120 g Ca(NO3)2. The results of the observation showed that the treatment of the addition of Ca(NO3)2 fertilizer had a very significant effect on all observed variables, except for the diameter of the lettuce plant. The optimum addition of Ca(NO3)2 for lettuce was found at 90.04 g with a maximum yield of 207.92 g.

Response of Salak Seedling (Salacca edulis L.) Growth to Endomycorrhizal Spore Doses on Volcanic Sand and Sea Sand Carrier. Endomycorrhizae has several benefits, such as increase water absorption and nutrients of plant, protect plants from root pathogens and toxic substances, play a role in improving soil structure, and increase nutrient solubility. This study aimed to determine the growth response of salak seedlings to doses of endomycorrhizal spores in media carrying volcanic sand and sea sand. This study used a factorial randomized block design (RBD) with two treatments i.e. the number of spores and the type of carriers media. The results showed no significant interaction between the number of mycorrhizal spores doses with the carrier media on all observed variables. Spores doses significantly affected stem diameter and root mycorrhizal infection variables. The highest stem diameter was achieved at the dose of 75 spores that was 1.60 cm which was significantly different from control (1.28 cm), whereas the highest root infection was obtained at the dose of 225 spores (92.50%) which significantly higher than control (36.25%). At the observation of 4 MAP (month after planting) the highest root infection was obtained at the dose of 150 spores (82.50%) compared to control (10.00%). Volcanic sand carrier media produced the highest plant dry weight (3.59 g) which was significantly different to the sea sand (2.43 g).

This study aimed to determine the effect of plastic mica container size with a total of 15 pieces of packaging and determined the best treatment for the shelf life of strawberries (Fragaria sp). This study useds a complete randomized design methodology (CRD) with one treatment, namely the type of plastic mica container size with various types of packaging types as follows: type 1 (K1), type 2 (K2), type 3 (K3) and number 15 fruit packs. The observed variables were weight loss, hardness level, shelf life, organoleptic test, respiration rate and vitamin C. The size of the packaging containers affected the physico-chemical changes in the strawberries. The treatment influenced the physico-chemical changes in the strawberries, such as the rate of respiration and vitamin C levels. The best packaging size was the smallest size (K1 ) K2 and K3 packaging container sizes. This is indicated by the lowest weight loss variable, with the value of 0.20%, the lowest value of respiration rate (20.61 CO2/ kg/hour), the highest vitamin C content (72.89 mg/100g), while in the organoleptic test, the smallest container size resulted in the highest score in fruit colour, container size has a score highest in the observation of fruit color, fruit appearance and fruit aroma. Observation of the shelf life of strawberries showed that the container size of K1 (the smallest) had an average shelf life better than K2 and K3. K1 container size produced a shelf life average of 4 days while K2 container size produce a shelf life average of 3,4 days. The shortest shelf life average was recorded in the K3 container size with a value of 3,2 days. It is concluded that the shelf life of strawberries in a packaging container at a temperature of 28-30ºC can be as long as 4 days.

Response of Growth and Yield of Sweet Corn to Dosage of Spores of Indigenous Endomycorrhizae. Endomycorrhizae is a form of mutualism association between fungi (myces) and roots (rhiza) of higher plants. The symbiotic relationship that occurs at the roots is mutually beneficial. Plants can provide carbon organic compounds for fungal growth, whereas fungi benefit plants by increasing nutrient uptake, water, producing enzymes, antibiotics and other compounds given to host plants. The study was conducted to know the effect of dosage of spores of endomycorrhizae indigenous to growth and yield of sweet corn. The experiments were carried out in laboratories and greenhouses. The design used was a completely randomized design with one factor namely the dose of spores of endomycorrhizae consisting of three levels, i.e. D0 = without inoculation of endomycorrhizae, D1 = 75 spores of endomycorrhizae/plant, and D2 = 150 spores of endomycorrhizae/plants. The results showed that dose of spores of endomycorrhizae treatment had a significant effect on growth and yield of sweet corn. The highest fresh weight of cob was obtained at a dose of 150 spores/plant, namely 181.33 g / plant. Based on the results of this study, it is necessary to conduct research in the field using a dose of 150 spores of endomycorrhizae per plant.

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.

Agrobacterium tumefaciens Mediated Genetic Transformation of acvB Gene in Potato (Solanum tuberosum L.). Genetic transformations are now routinely applied to plant mediated by Agrobacterium tumefaciens as the most convenient technique. This study aimed to prove the success of A. tumefaciens mediated genetic transformation in potato. A. tumefaciens LBA (pBI 121) and explant of potato shoot were used in this study. Explants were grown in vitro on Murashige and Skoog media. Transformation was implemented using smear technique by smearing A. tumefaciens to injured explant. Experimental groups consisted of two groups: control group which did not receive transformation treatment and treatment group receiving transformation treatment. Explant growth was observed through the presence of shoots, branches and the shoot height. Explants in the treatment group resulted in a higher number of shoots, branches, and shoot heights compared to control. Phenol compounds appear in explant epidermal tissue, indicating the wounds produced by A. tumefaciens infection, thus the gene predicted to be transformed. Identification by PCR is needed to prove the existence of the acvB gene in potato plants genome, using acvB specific PCR primer as the marker, such as (5?-CCCT CTAG AGAC CCGC GCCA AGGCG-3?) and (5?CGCG TCGA CCTT GTCG GAAAG -3?) with 540-bp in base pair size produced.
