Abstract

This study aims to determine the effect of concentrations of Rooton F, young coconut water, and cow urine on the growth of cuttings patchouli stem. Patchouli plant (Pogostemon cablin Benth.) is one of the important essential oil producing plants. The export volume of essential oils has always increased, in 2001 it reached 5,080 tons. Indonesia is the main supplier of patchouli oil in the world, which is almost 90% of the world's needs (Emmyzar, 2004). However, in recent years, patchouli oil exports have shown a downward trend. The cause of the decline was the limited ability to produce patchouli oil. Therefore efforts to increase the production of patchouli oil by way of development patchouli plants wide open. One of these efforts can be done by producing patchouli plants that have good quality. Patchouli plant propagation can be done by cuttings. The success of cuttings can be seen from their roots. Good rooting will produce quality plants fine too. Auxin is a type of plant hormone that can stimulate root growth. Rooton F is an example of a synthetic ZPT ingredient, while young coconut water and cow urine are natural ZPT ingredients. The three materials have their advantages and disadvantages. With the difference in the content of the three ingredients, it will also have a different effect on the growth of patchouli cuttings. In observing the number of leaves aged 6 wap, 75% rooton-F gave a yield of 4.67 leaves and was not different from the treatment of 75% coconut water, 50% cow urine, and 100 cow urine. At 5 wap, 75% and 100% treatments gave the effect is the same and different from other treatments.

Abstract

The purpose of this study was to study the effect of the thickness of low density polyethylene plastic as a packaging material for White Oyster Mushrooms on the modification of O2 and CO2 gases and the physical changes that occur during storage. P Completely randomized design (CRD) was used to analyze data on changes in the composition of O2 and CO2 and followed by a T test if the analysis of variance showed that different treatments had a significant effect on changes in O2 and CO2 concentrations. The results of the diversity test showed that the treatment of differences in LDPE plastic thickness had a very significant effect on the concentration of O2 and CO2 gases in the plastic packaging. The thickness of LDPE plastic 0.04 mm is the best thickness that is able to maintain the quality of white oyster mushrooms with a texture value of 0.022 mm/g.sec, weight loss of 0.74%, reduction of water content of 1% and an average minimum oxygen concentration in the package of 3.2 % and the maximum concentration of carbon dioxide in the package is 8.2%. The highest decrease in water content at 0.03 mm thickness was 1.3% and the lowest at 0.08 mm thickness was 0.63%. The lowest respiration rate was 21.71 mlCO2/kg/hour which occurred at a thickness of 0.08 mm on the 5th day of storage. If the respiration rate of a commodity can be matched with the permeability of the film on the package, then a favorable passive atmosphere condition can be achieved within the package. This method is commonly known as Modified Atmosphere Packaging (MAP).

Abstract

This study was conducted to determine the effectiveness of using N, Si fertilizers at certain doses to prevent further attacks caused by SCSMV. The results showed that each increase in the dose of N fertilizer on sugarcane plants will accelerate the incubation period with a regression value of 1.038% and affect the increase in intensity SCSMV attack of 3,063%. At each increase in fertilization the dose of Si can inhibit the incubation period of SCSMV and can decrease SCSMV attack intensity of 7.018%. There was no significant difference in the growth of sugarcane shoots in the F test. The use of N dose of fertilization would affect the growth process, such as plant height in increasing the N dose would affect the highest plant height increase in the 8 kw/Ha treatment. In the Si fertilization treatment there was a significant difference that each increase in dose would increase the process of plant height growth. Sugarcane (Saccharum officinarium L.) is one of the plants belonging to the grass species (Gramineae). This plant is used as raw material for sugar. Low sugar production affects the fulfillment of national sugar needs. Many things can affect the decline in sugar production, including the explosion of pests and sugarcane plant pathogens. One of the main pathogens is Sugarcane streak mosaic virus (SCSMV) which in recent years has attacked sugarcane plantations in Indonesia. The role of many nutrients needed by plants. The use of appropriate N nutrients can increase yields, and the application of Si elements can protect plants from OPT attacks.

Abstract

This study aims to determine the effect of adding a mixture of coffee litter + Gliricid + durian and Urea and its combination on the growth of Pontoscolex streak worms and the population of soil microorganisms, especially bacteria and fungi, and whether worm growth can increase the population of bacteria and fungi. The results of this study indicated that the addition of litter (coffee+Gliricidia+durian) ja increased worm biomass by 29% compared to the addition of Urea (0.28g/head) and increased the diameter of the worms by 12% compared to the addition of Urea(0.25mm/head) . The combination of litter and Urea increased the bacterial population by 16% compared to the addition of Urea alone (32.105cfu/ml), while compared to the addition of only litter (34.105cfu/ml) the bacterial population increased by around 9%.

Abstract

The purpose of this study was to determine the pattern of LAT ecdysis especially the Freshwater Lobster of the Cherax quadricarinatus type, aged 76 days to 116 days. The purpose of this study was to determine the pattern of LAT ecdysis, especially the Freshwater Lobster of the Cherax quadricarinatus type, aged 76 days to 116 days. This research was conducted at the Experimental Station for Freshwater Aquaculture Sumber Pasir, Faculty of Fisheries and Marine Sciences, Universitas Brawijaya from July to August 2007. The method used in this study was a descriptive method in which this research gave an accurate description of an individual or group. Data collection techniques by way of direct observation. Then the data were analyzed statistically using the SPSS computer program version 11.5 for windows. Using simple linear regression analysis Crustacean growth is related to molting. In crustaceans, changes in shape and size can only occur if the hard calcareous exoskeleton is removed before the new cuticle hardens. Periodic molting or ecdysis continues by separating the old cuticle from the new instar, holding water absorption through the digestive tract, which is a characteristic of the Crustacea group as well as other aquatic insects. Then, the absorbed water is gradually replaced by biosynthesized protein, this growth process takes place continuously, the molting cycle can be divided into four stages, namely: proecdysis, ecdysis, metecdysis and intermoult.
