Abstract

Quail is one type of poultry that must be developed because it has the potential to produce animalprotein needs for humans, namely meat and eggs. Because the meat and quail eggs are in greatdemand by the community, their maintenance is almost evenly distributed throughout Indonesia.Privileges of quails include fast production, do not require large capital, easy maintenance, and donot require large tracts of land. The aimed of this experiment was to determine the effect of providingdragon fruit skin-fermented (DFSF) with fungi Neurospora crassa as an alternative feed material tothe performance of quails. The research method are experiments using completely randomized design(CRD), with 5 treatments and 4 replications. if there is a real or very real difference that will be followedby Duncan's distance test. The treatments given are: A = without giving DFSF, B = giving 4% DFSF,C = giving 8% DFSF, D = giving 12% DFSF and E = giving 16% DFSF. The results showed thatdifferences in the level of DFSF in quail ration gave no significant effect on feed intake, body weightgain and feed conversion of quail ration. It can be concluded that the administration of DFSF up tothe level of 16% in the ration can be used as alternative feed ingredients without affecting feed intake,body weight gain and quail feed conversion.

Abstract

The difficulty of root formation cuttings dragon fruit plants is influenced by several factors; The first disease that often occurs is a rotten stem. This disease usually strikes in early planting dragon fruit, dragon fruit plants often have decay at the base of the stems, there are brown and white fur. The decay caused by excessive soil moisture so it appears that the fungus that causes rot (Sclerotium rolfsii sacc). Both the stem to rot can also be caused when the rod directly planted, the sap is still wet rot can give effect to the dragon fruit cuttings. One attempt to increase the percentage growth of cuttings is using Indol Butyric Acid (IBA), which is a type of plant growth regulator that is used to stimulate root formation. The aim of this study was to investigate the effect of indole butyric acid (IBA) on the growth of stem cuttings of red dragon fruit (Hylocereus costaricensis). This research was conducted at the village Sidorukun, District Pangkatan, Labuhan Batu Regency, with a height of ± 39 m asl, from July to September 2016. The research design used in this study is a randomized block design with 5 treatments the concentrations of the hormone IBA consists of A0: 0 ppm, A1: 4000 ppm, A2: 5000 ppm, A3: 6000 ppm, A4: 7000 ppm and 5 replicates so that there are 25 total plot trials. Parameters observed that the percentage of the emergence of shoots, age appeared shoots, shoot length (cm), fresh weight of shoots (g), dry weight of shoots (g), root length (cm), fresh weight of the root (g), the volume of roots (g), root dry weight (g). Data were analyzed using linear models continued with Duncan test. The results obtained showed that the administration of Indole butyric acid (IBA) significantly affected the percentage of observation parameters appear buds, shoots emerging age, number of shoots, root length, fresh weight of root, root volume, and root dry weight. But it did not affect the parameters of observation shoot length, fresh weight of shoots, and buds dry weight.  Keywords:  dragon fruit plants (Hylocereus costaricensis), Indole butyric acid (IBA), cuttings, growth.   References Anita, 2008.

Abstract

The purpose of this research was to assess the effect of different potassium doses and fertilizer sources on growth rate and time of bulb formation of garlic (Allium sativum L.). The research was conducted in April to Agustus 2019 in Sidomukti Village, Bandungan District, Semarang Regency and at Ecology and Crop Production Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang. The research used a factorial randomized block design with three groups. The first factor was the dose of potassium fertilizer which consisted of a dose of  60 kg K2O/ha, 120 kg K2O/ha, 180 kg K2O/ha, and 240 kg K2O/ha. The second factor was the source of potassium fertilizer which consisted of KCl, ZK, and KNO3. Parameters that collect were time of bulb formation, growth rate, relative growth rate, and potassium absorption of bulb. The data obtained were analyzed by analysis of variance and obtained further by the Duncan test (Duncan's Multiple Range Test) at a significance level of 5%. The results showed that the application of ZK and KNO3 fertilizers at 240 kg K2O/ha had been able to increase the growth rate and the relative growth rate. The higher dose of fertilizer was increasing of potassium absorption of the bulb and made time of bulb formation getting slower.   References Ahmed, M. E., El-Kader, N. I.

Abstract

ABSTRACT  This study aimed to evaluate the effect of mycorrhiza and Penicilliumsp on the growth and production of mung beans in paddy land. The design of this experimental research was a factorial Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was the dosage of mycorrhiza consisting of 0 g/plant; 5 g/plant; 10 g/plant; and 15g/plant. The second factor was the type of phosphate solubilizing microbes consisting of withoutPenicilliumsp; Penicilliumspfrom Mursala island (20 ml/plant); Penicilliumsp collection taken from soil biology laboratory of faculty of agriculture USU (20 ml/plant). The results showed that the dosage of Mycorrhiza and Penicilliumsp were not significantly affected the height of mung bean plants, however, it significantly affected the population of Penicillium sp. The application of 15 g Mycorrhiza with Penicilliumsp from Mursala was the best treatment for the growth of mungbean plants at 4 weeks after planting (42.98 cm) and the interaction of Mycorrhiza15 g/plant and PenicilliumspMursala produced the best seeds/plant of 16.76 g/plant.   REFERENCES  Adiningsih, S. 2004.
