Abstract

ABSTRACTEffects of pulsing and low temperature storage on the vase life of rose cut flowers had been studied. To prolong the postharvest life or flowering display of rose cut flowers by pulsing them after picking, that is, putting the stems in a sugar solution. The objectives of this study was to get the best pulsing time, vase life and quality change i.e the wilting percentage of rose cut flowers. First step of this research was pulsing the rose cut flowers with a coconut water for 1, 2, and 3 hours, then stored those flowers in low temperature 5,250C. The results showed that pulsing the rose cut flowers in coconut water for 2 hours is the best pulsing time and can prolong the vaselife until 40 days.Keyword : Pulsing, coconut water, rose cut flowers, cold storage

Abstract

ABSTRACTThis study aims to determine the differences of imago characteristics of S. oryzae and S. zeamais onrice and corn. This research used descriptive observational method by identifying the externalmorphology and describe all the observed parts. Morphological characters were observed byobserving the external morphological features of insects including differences of body size, bodycolor, antenna, rostrum, and other morphological features. Observation of body color by binocularmicroscope included overall body color, color and form of elytra, foot color, antenna and rostrum.Body sizes were measured by using ruler or millimeter scale paper by means of insect anesthesia byusing ethyl acetate, then stretching the body of insects in full on white paper with millimeter scaleplaced underneath the insects. Results of the study indicated that the S. oryzae imago were brightblack or brownish black, having four oval pictures on elytra, and reddish brown legs. Imago of S.zeamais were solid black or dark color with four yellowish brown pictures on elytra, and brownishyellow legs. The average body length of S. oryzae young adult was 2.16 mm (ranged from 2.0 to2.4 mm), and for adult was 3.36 mm (ranged from 3.0 to 3.7 mm). The average body length of S.zeamais young imago was 2.54 mm (ranged from 2.4-2.7 mm), and 4.78 mm (range 3.7 to 4.7 mm)for the older imago. The observation of adult male and female body size differences of S. oryzaeand S. zeamais showed that adult females were larger than males. The roustrum (snout) of femaleinsects was longer and bigger, while the male imago was shorter and thinner. Abdominal end of themale imago when viewed from the lateral direction showed a curved shape and when viewed fromthe posterior direction showeda tapered shape. The female abdomen when viewed from the lateraldirection was not curved or straight back, and seen from the posterior direction was rather enlargedand blunt. The average length of S. oryzaerostrum was of 0.16 mm (ranged from 0.1 to 0.24 mm)for adult males and 0.32 mm (range 0.2-0.4 mm) for adult females, while S. zeamais was 0.5 mm(ranged from 0.4-0.6 mm) formale imago, and 0.62 mm (range 0.5-0.7 mm) for female imago.Antenna of S. oryzae and S. zeamaisshowed of an angle shape with a club type. The averageantenna length ofS. oryzae was 0.94 mm (ranged from 0.8 to 1.1 mm) for adult males and 1.46 mm(range 1.2 to 1.8 mm) for adult females;S. zeamais antenna length was 1.9 mm (range 1.7- 2.1 mm)for adult males, and 2.5 mm (ranged from2.2-2.6 mm) for adult females. The sex ratio difference ofS. oryzae and S. zeamais was 0.8 (ranged from 0.7-0.9) for S. oryzae, and 0.7 (ranged from 0.67 to0.85) for S. zeamais.Key word : Characteristics of adult.

ABSTRACTThe study aims to analyze the adequacy of water in the area Tonsewer for the growth of tomato plants and corn. This research conducted in Tonsewer village, West Tompaso. Materials and equipment use are drill, ring sampels, hoes, sholves, machetes, laboratory equipment, sack,plastic, rubber, 10 years of climate data (monthly rainfall, humidity, watering time,wind speed, maximum and minimum temperatures), soil data, and plants data.The result using the model of CropWat8 that condition the availability of water for crops as tomatoes and corn sufficient available. Planting June 1st decreased soil moisture ahead of the third phase of growth of tomato plants.Tomato plants need sufficient water in the initiation phase/transplanting and in the initial phase until the final disposal phase of fruitformation. Planting time June 1st and July 1st the reduction soil moisture at planting time these two accurred in the third growth phase reach a position under conditions readily available in the fourth growth phase.Keywords : water availability, evapotranspiration, CropWat8 model

Benefits of research that can provide information to the community and local government about the quality of water around the Site TPA waste, including: Groundwater quality, surface water and leachate. The research was conducted using survey method and the data was analyzed by desktritif, tabelaris and garif. TPA sampling point using GPS (Global Position System), and determination of sampling point by purposive sampling technique. The parameters observed through physical, chemical and microbiological aspects. The results showed that the total coliform parameters for springs, wells and boreholes respectively were 17, 27 and 2 APM / 100ml, which means exceeding the quality standard of water in accordance with Permenkes N0. 492 of 2010. The quality of leachate river water with BOD parameters 110 mg / l, COD 323 mg / l, TDS 1830 mg / l, and Nitrate 13.10 mg / l which has exceeded the quality standard according to class II based on PP. No. 82 in 2001. Leachate quality of inlet leachate and leachate drainage with COD, TDS and Nitrate parameters were 898 mg / l, 4130 mg / l and 111.01 mg / l and 334 mg / l, 5170 mg / l, respectively, L and 144.6 mg / l exceeding the leachate effluent quality standard.

ABSTRACTThis study aims to determine some physical properties of soil on strawberry plantation land in Rurukan urban Tomohon. The things observed in this research are: Soil Texture Weight Fill Soil Soil Porosity, Soil Permeability and Soil Water Level. Implementation of research activities in the field is done through the stages as follows: Data collection / soil samples were conducted on plots of strawberry plantation at the 15th week after planting consisting of: Land does not use compost and without plastic mulch (K0P0). Land with compost (K) and plastic mulch (P) with compost dose level, namely: 1) 0 ton / ha (K0P1); 2). 15 ton / ha (K1P1); 3). 30 ton / ha (K2P1); 4). 45 ton / ha (K3P1); And 5). 60 tons / ha (K4P1). That with compost treatment with different doses and plastic mulch and soil treatment resulted in differences in the percentage of sand, dust and clay fraction which then gave different values on the weight of soil contents, porosity, permeability and water content in strawberry plantation.Keywords: study.

ABSTRACTThis study aimed to determine the composition of the species and structure of mangrove forests in Sapa Village South Minahasa District. The study was conducted in October-November 2016. The Important Value Index (INP) obtained from vegetation analysis was used as an indicator to describe the composition and structure of mangrove forest. Plot assisted path method is used in vegetation analysis. Created 10 lane hayal with a width of 200 m divided into 10 segments, there are 69 plots to obtain data and species of mangroves. This study showed that 7 species from 4 mangrove families in Sapa Village, namely : Rhizophoraceae (Ceriops Tagal, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorhiza), Sonneratiaceae (Sonneratia alba), Avicenniaceae (Avicennia officinalis), Meliaceae (Xylocarpus granatum). Species with the highest INP values are Sonneratia alba at all growth rates, trees with INP values of 178.63%, stakes 101.14%, and 65.37% seedlings. The mangrove trees in Sapa village are found in a diameter range of 10 to 20 cm.Keywords : composition and structure vegetation, Sapa Village.
