Abstract

ABSTRACTThe national park has an important role in the preservation of biodiversity, became the house for animals to living wildly. Otus manadensis is one of wild animals in the Bogani Nani Wartabone National Park is endemic species Sulawesi who have ecological role as pest controller. Quantitatively the spread of this species is not known for certain. This research conducted approximately 3 months from September – December 2015. Used methods of the point count and transect line. The point of observation is systematically divided into 4 segments based on the height of the surface of the sea. Three segments including in the national park area that is located in the Mount Kosibak while other segments is a production area or field located near the settlement. Research results obtained that Otus manadensis prefer areas with a good vegetation cover. There is a very high correlation between the condition of the vegetation cover with the density of Otus manadensis in Mount Kosibak. Otus manadensis density higher on the vegetation with basal area and importance value index is high.Key word : Population, Otus manadensis, Vegetation, Segment, Mount Kosibak, TNBNW

Abstract

ABSTRAKThis research aims to know the influence of leaf fertilizers and shade on the growth ofGyrinops verstegii (Gilg) Domke under water stress. This research was conducted in the greenhouse of Faculty of Agriculture, University of Sam Ratulangi Manado, from June to August2013. Spit plot design is used in this research. Shade as main plot consists of two levels,namely: 1 layer of paranet N1 (light intensity ± 40%) and 2 layers of paranet N2 (lightintensity ± 16%). Doses of fertilizer as sub-plot consists of 3 levels: P0 as a control (nofertilizer), P1 0.012 g/plant and P2 0.024 g/plant. The fertilizer was given every week for 2months. The effects of both shading and fertilizer treatments were not significant on plantheight and stem diameter under water stress.Keywords: Gyrinops verstegii, water stress.

ABSTRACTThis reseach aims study the wilt desease of bacterial on potato held in Mondoinding District for3 monts from January to April 2016. Laboratory studies conducted at the Laboratory ofMicrobiology and Plant Pathology, Faculty of Agriculture Unsrat Manado and in the field whichis in Modoinding District. The research in the laboratory is to determine the pathogenic bacteriathe causes wilt disease while in the field is to determine the incidence of the disease thet carriedout in the Linelean village, Makaaroyen village and Palelon village using subplots extent of 2 mx2 m and the spacing used between the plants is 40 cm x 20 cm with the number of samples ineach subplot at 22 plants, to study the incidence of the disease by the method of survey andsampling deliberate on potato experiencing symptoms of wilting. The result showed that thecharacteristic of pathogenic bacterial causing wilt disease on potatoin the Modoinding Districtthat Ralstonia solanacearum, is the symptoms of the plants become wither, the stem becomesbrown and rotten. The result of the study the incidence of wilt diseases caused by pathogenicbacteria in the field have differences with the incidence of wilt diseases caused by pathogenicbacteria at each location, with the highest incidence is Linelean village with 51.58%, followed by44.88% Palelon village and the Makaaroyen village 40.78%. The incidence of bacterial wiltdisease in Modoinding district each location of the observations is increasing every week withthe highest incidence of will disease caused by pathogenic bacteria is an average of 78.62% andthe lowest attack which is an average of 5.45%.

ABSTRACTThe Research Anthocephalus growth macrophyllus (Roxb.) Havil) at various doses of compost have been carried out in the greenhouse of Faculty of Agriculture, forestry science courses Unsrat. The purpose of this study was to determine the effect of the growing medium compost on growth Anthocephalus macrophyllus. This study uses a randomized block design (RBD), with five treatments and five replications each test consists of 6 plants. Compost growing media treatment levels given are A control (without fertilizer) B (0.5 kg), C (1kg), D (1.5 kg), E (2kg). variable observed that the increase of plant height, stem diameter increase, in the number of leaves, root volume and dry weight of the plant. This study uses a randomized block design (RBD).The results showed that the growing medium compost significant effect on the growth of high and volume root crop seeds Anthocephalus macrophyllus. And the effect of high growth and volume Anthocephalus best root seedling compost macrophyllus is giving treatment that is as much as 1.5 kg at treatment D.Keyword : Compost, Seed Growth Anthocephalus macrophyllus

Abstract

ABSTRACTNorth Sulawesi province known as one of the largest producer of nutmeg crop in Indonesia. North Sulawesi supplies about 75% of the needs of nutmeg world with exports ranging between 1000 to 2000 tons. Processing nutmeg nutmeg syrup is one way of diversification of nutmeg. Small and Medium Industries (SMI) "Sari Fruit" is one nutmeg syrup producers in North Sulawesi, especially in the district of Sitaro. However nutmeg syrup products on the market has not been specified expiration date. One method that can be used in determining the shelf life of foodstuffs is ASLT (Accelerated Shelf Life Testing). The benefits of this research is to increace public knowledge about the processing of nutmeg syrup, and to add nutmeg syrup product competitiveness. The nutmeg syrup stored at a temperature of 30 ° C, 35 ° C and 40 ° C for 12 weeks (90 days). The parameters used to analyze the degradation products are nutmeg syrup, pH. The results showed that the shelf life based on pH nutmeg syrup at normal storage temperature of 30 ° C is 52.48 weeksKey words : nutmeg syrup, ASLT ((Accelerated Shelf Life Testing)

Abstract

ABSTRACTStarfruit (Averrhoa bilimbi) known as star fruit acids, this is due starfruit containsfolic acid. In the Minahasa region known as starfruit bottle, starfruit is one of the agriculturalproducts that have not received the attention and good handling. For that need to bedeveloped processing technology in the form of processed foods such as hard candies. Hardcandy is one of the non-crystalline candies that have a hard texture, shiny and translucentappearance. The purpose of research is to determine the concentration of sucrose and glucosesyrup right by analyzing the chemical components as well as measuring the level ofpreference panelists include taste, aroma, texture and color of hard candies starfruit. Thisstudy uses a completely randomized design (CRD) each consisting of three replications withA treatment (70% sucrose and 30% of glucose syrup); B (75% sucrose and 25% of glucosesyrup); C (80% sucrose and 20% of glucose syrup); and D (85% sucrose and 15% of glucosesyrup). The results showed that the hard candies starfruit with treatment A, B, C, and D meetthe requirements of SNI when viewed from the water content 0.40 - 1.03%, ash content of0.01 - 0.05%, reducing sugar 12.84 - 17.71% and total acids 1.06 - 1.20%. The greater theamount of concentration sucrose added will produce candy starfruit increasingly violent. Theconcentration of sucrose and glucose syrup is right for the manufacture of hard candy starfruitis concentration sucrose 85% and 15%. The results of organoleptic test sucrose concentrationof 80% and 20% glucose syrup is the preferred treatment panelists.Keywords: Starfruit, Sucrose, Glucose Syrup, Hard Candy.
