Abstract

ABSTRACTThis study aims to determine the amount of the addition of tapioca flour right in making biscuits purple sweet potato (ipomoea batatas L). Analyze the nutritional content of gluten and casein-free biscuits are produced. Evaluate the sensory quality of the biscuits are produced. This study uses a completely randomized design with mixing treatment with a purple sweet potato starch and tapioca starch. Each - each 4 treatments performed 3 repetitions. Treatment A (10% addition of tapioca starch), B (15% addition of tapioca starch), C (20% addition of tapioca starch), D (25% addition of starch). Variables were observed in this study is the chemical content of the biscuit the water content, ash content, protein content, fat, crude fiber, carbohydrate, calorie value. Based on test results obtained organoleptic formula mixture of sweet potato flour and tapioca flour are the preferred panelists namely D (Extra 25% starch) and has the chemical content of water content (3,25%), ash content (2,80%), fat ( 22,74%), crude fiber (0,76%), protein (2,91%), carbohydrates (68,28%), a calorofic value (490,11 kcal).

Abstract

ABSTRACTThe aims of this research were to find the effectiveness of PGPR and P. fluorescens inpreventing wet rot that caused by E. carotovora. This research was conducted in VillagePaslaten, Tomohon city. The research was conducted in three places, namely The Laboratoryof Plant food and Horticulture of Protection North Sulawesi Province, cauliflower plantinglocation in Tomohon and the laboratory of Microbiology and Plant Pathology Faculty ofAgriculture Unsrat Manado. This research used RCBD with 4 treatments and 6 repetitions.Observation was done in 6 times and the time interval was one week. The result of the studyshowed several symptoms that happened to the cauliflowers, they were: the leaves wereblackish brown, shrank and looked pale, and also the small wet symptom sections becomewiden quickly. The infected soft produced a bad oder. This research showed the impact ofcollaborated treatment of PGPR and P. fluorescens was more effective since it showed ansignification different from giving PGPR or P. fluorescens separately that did not show anyimpact. The result of isolation showed that the bacteria which caused the wet rot in plantcauliflower in Tomohon was bacteria Erwinia Carotovora looking form its characteristic,creamy white colonies, slimy, shiny, convex and looked flat.Keyword: Effectiveness, Cauliflower, Soft root, Erwinia carotovora, Plant GrowthPromoting Rhizobacteria, Pseudomonas fluorescens.

The research was taken by using the survey method on leeks andshallot plants in Ampreng village, Langowan subdistrict. The researcher had used thediagonally slicing method i.e determining 5 sub plots on the location of taking the sample.Taking the sample had been done by using the interval of time along one week for three timesof observation. The finding of the research showed the average of the highest population ofLarva S. exigua went to Shallots i.e 1.44 tails, meanwhile the population of Larva on leeksonly got 0,67 tail. The highest average of Larva S. exigua attack went to Shallots plants, i.e.28,07 %, meanwhile leek plant only 14,81 %. The result of the independent analysis test“sample T-test” showed there are found the real differences of the population and thepercentage of Larva S. exigua attack on leeks and shallot plants.Kata kunci : Population, Percentage, Leek, Shallot, S. exigua

ManengkeyThe purpose and benefits of the research to determine the incidence of rust on peanut plants in the District Tompaso and Kawangkoan Minahasa, and the benefits of research can provide information to the relevant agencies, especially to farmers about the existence of this disease in order to prepare a peanut crop control strategies of the disease. The research was conducted in three village namely Pinabetengan, Kanonang and Kayuuwi, District Kawangkoan, Minahasa, and the study lasted for four months. The results showed that the symptoms ofdisease-causing pathogen attack or rust fungus Puccinia arachidis on peanut plants occur at all levels of the age of the plant is vegetative and generative growth. Pathogens forming patches on the surface of the lower and upper leaves with urediospora there are more obvious on the lower leaf surface than the upper surface of the leaf. The results of microscopic observation showed that urediospora shaped somewhat oval, urediospora with brownish colored water media while the media Laktofenol Cotoon Blue color changes such as a golden brown. Furthermore, the incidence of fungi that cause rust on peanut plants are in the village Kayuuwi lowest with an average percentage of 17.75; The village following Pinabetengan with an average percentage of 19.75; and was highest in the Village Kanonang with an average percentage of 22.67.

Each village selected three planting locations Thailand andlocal papaya varieties. Paerts of plants observed is the fruit. The results showed that thehighest population of mealybug P. marginatus found in papaya varieties Matungkas Thailandvillage, 49,66 grains egg, nymph 557,00 individual, 8,66 imago male individual and femaleimago 138,33 individual. Furthermore, the population in the village Laikit, namely 36,33grains egg, nymph 635,33 individual, 1,00 imago male individual and female imago 40,66individual. The next lowest is in the mralybug population Dimembe with an average of148,66 grains egg, nymph 412,00 individual, the individual 4,66 imago male and femaleimago 58,66 individually, while the local varieties found in the highest population Laikitvillage with an average of 318,66 nymph individual, and female imago 20,33 individual. Thevillage Matungkas second highest with an average of 55,00 grains egg, nymph 214,00individual, 1,00 imago male individual and female imago 40,66 individual. FurthermoreDimembe village which is the lowest population, seen from an egg stadia grains 36,00,214,33 nymph individual, and female imago 38,33 stadia individual.Keyword : Population, Papaya, Paracoccus marginatus.

ABSTRACTCandied tomato is a tomato processing alternatives that can be done to take advantage of tomatoes were very susceptible to damage after harvest and are often consumed in fresh form. The purpose of this study to determine the effect of the addition of sugar to the physicochemical characteristics of candied tomatoes and measure the level of a panelists against to candied tomatoes. The research arranged using Factorial Completely Randomized Design with the addition of sugar multilevel treatment. Results of research for the candied tomato water content ranged from 18.45 to 30.94 % . The water content is highest in treatment A2 is the addition of sugar 40 % , while the water content was lowest for the treatment A3 is the addition of sugar to 50% with the drying temperature used in all treatments, 550C. The results of the analysis of sucrose concentration ranged from 44.81 to 70.80 % . Sucrose concentration is highest in the treatment of A4 is the addition of sugar to 60% with an average of 70.80 % , while the sucrose concentration was lowest for the treatment A1 is the addition of sugar to 30% with an average of 44.81 %. The results of the analysis of vitamin C for four treatments ranged from 2.78 to 4.08 mg / 100gr . Texture analysis for the four treatments ranged from 2.8 to 4.1 kg/cm2 . Sensory testing candied tomatoes with parameters of taste , color and aroma is the preferred sample A3 is the addition of sugar 50 % .Keywords : candied tomatoes , physicochemical and sensory properties
