Abstract

Research of Optimizing Natural Growth Regulatory on Red Onion Extract (Allium cepa fa. Ascalonicum) as a Growth Root of Tin Crop Fruit Cultivation (Ficus carica) was a study which aims to utilize red onion extract as a trigger of root growth in the multiplication of tin fruit plants through stem cuttings. Utilization of onion extract in various concentrations were 0%, 0.5%, 1%, 1.5% and 2%. This study used the method of Randomized Complete Random Design (RAL) with the analysis of orthogonal polynomial quantitative data from 25 plant samples. The results showed that all treatments had an effect on the number and length of root of tin plant. The 1% concentration provides optimum results against the observed parameters compared to control and other treatments. Achievement of longest root long optimum point was at concentration 1.14% while the optimum root number was at concentration 1.07%.

Abstract

This study aims to determine the types of pests that attack the various stages of plant development strawberries and measure the extent of damage to strawberry plants caused by pests. These observations were made in Tlekung Experimental Station, Research Institute for Citrus and Subtropical Fruit, Batu municipality, East Java in July until September 2018. The strawberry plants were observed consisting of three varieties, namely Sweet Charlie (SC), Dorit (DR), and Early Bright (EB). Each variety consisted of 20 plants in the vegetative and generative phases with different planting locations were in the screen house and open fields. Observations intensity of pest attacks were divided into three, namely the intensity of leaf-eating pests, pest mites and pests of fruit eaters. The results showed pests that attack strawberry plants consist of the phylum Mollusca and Arthropods. The highest intensity level of pest attacks occur at the location of strawberry cultivation in open fields than the strawberries grown in the screen house that is the pest mites reached 91,25%, which is included in the category very heavy attack on the variety SC. SC varieties were most susceptible varieties against leaf-eating pests and pest mites. Susceptibility to pests highly dependent on the age of the plant, character growth, and morphological characters.

Abstract

This research is to study the effect of composting time and media composition of sugar palm solid waste and  straw to an yield of straw mushroom (Volvariella volvaceae (Bulliard Ex Fries) Singer). The research held on May until June 2018. Location of this research is at Kedungsari village, Bandongan sub-district, Magelang regency. The altitude is 332 meters. Factorial experiments 4 x 3 in randomize complete block design that consist of 4 repetitions. First factor is composting time 3, 5, 7, and 9 days. Second factor is media compositions of mix sugar palm solid waste and rice straw (2% : 10%), (4% : 3%), (10% : 10%). The result of this research shows that lenght of composting declines total number of fruits bodies, total weight of fruits bodies, and biological  efficiency. Biological efficiency of  media composition about 10.22% - 19.16%. Media composition of sugar palm solid waste and rice straw do not  effect all observe parameters. Top rack position gets higher yield on total number of fruit bodies per plot, total weight of fruit bodies per plot, and biological efficiency.Composting time is three days on the composition media (10% : 10%) is more effective to the first harvest with the high yield of paddy straw mushroom.

Abstract

Research on Biofiltotacum - The optimization of stem waste (Nicotianatabacum) aims to create a bio-filter from cellulose extracts of tobacco stems as a form of ultrafiltration membrane for river water filters. Tobacco stem waste can be utilized as an efficient and effective membrane feedstock. This research is done by phase inversion method. Quantitative data analysis was obtained with the calculation of acetyl content that is 16, 89%. Acetylation data obtained is smaller than the standard of 40%. The amount of acetyl content can be affected by several factors, including duration of acetylation process, temperature, stirring speed, acetate amount, and also solvent amount. In addition, the small amount of acetyl may be caused by the cellulose content in the tobacco rod is not yet optimally isolated.

Abstract

The research on increasing the quantity of shallots (Allium cepa fa. ascalonicum L.) with various sources of kalium and sulfur, conducted in July until September 2017 in Sawangan, Magelang. The latitude is 400 m, with the soils regosol and pH 5,6. The research used factorial experiment (3x3) arranged in a randomized complete block design, with three blocks. The first factor is the source of kaliumwich consists of three levels, without kalium, KCl and KNO3. The second factor is the source of sulfur wich consists of three levels, without sulfur, ZA and Petro-Cas. The result of the research show that KCl fertilizer increased longest leaf length, fresh weight of bulb per plot and dry weight of bulb per plot. KNO3 fertilizer increased fresh weight of bulb per plot, dry weight of bulb per plot, fresh weight of stover and dry weight of stover. ZA fertilizer increased longest leaf length, fresh weight of bulb per hill, dry weight keep thr bulb per hill, fresh weight of bulb per plot, dry weight of bulb per plot, fresh weight of stover and dry weight of stover. Petro-cas fertilizer not increased in all observation parameter. The combination of treatments of kalium and sulfur sources give the same results on the fresh weight of bulb per plot and dry weight of  bulb per plot.

Abstract

This researchis about respons plant number of each planting hole on many varieties of peach bean (Phaseolus vulgaris, L.) indeterminate type was done since February up to May 2018 in Village Ngleses, Sub-distric Candimulyo, Distric Magelang at 434 m als with soil pH 6. The research using methode factorial design random group of two factor, with four repeat. The first factor is plant number of each planting hole, that is one, two and three plant and the second factor is kind of varieties of peach bean there are Balitsa 1 and Balitsa 3. The result from the experiment shawing that enhancement plant number of each planting holecan increasing of plant height, pods number per square meter and pods fresh weight per square meter, but decrease of pods number per plant and pods fresh weight per plant.The Balitsa 1 variety give high yield on pods fresh weight per plant and Balitsa 3 variety give high yield on plant height and the age offlowering is more fast. Plant number of each planting hole and varieties kind is not affect each other, so give a separate influence without  interaction
