ABSTRACT Study aims (a) to determine the effectiveness of Trichoderma sp., combination PGPR and Trichoderma sp., and PGPR to the development of diseases that attack strawberry plants, (b) to study the effect of application of Trichoderma sp., combination PGPR and Trichoderma sp. and PGPR for strawberry production. The experiment was conducted in the village Rurukan (Mahawu), subdistrict Tomohon Timur. Study lasted from March to August 2013. Experiments using a randomized block design with 4 treatments, as follows: Treatment A = Trichoderma sp., Treatment B = PGPR, Treatment C = combination of Trichoderma sp. and PGPR, and Treatment D = Control. The experiment was repeated 4 times. Data were analyzed using Minitab software ver. 14. Things that observed the symptoms of disease, number of shoots, roots and heavy weight of strawberries. The results showed that strawberry plants are not attacked by various diseases. Fungus Verticillium sp. encountered attack strawberry plants with very low intensity. The average number of shoots ever encountered on the 6.25 shoots PGPR treatment and lowest in the control treatment, ie 2.20 shoots . The average weight of the heaviest roots found in the PGPR treatment and 68.75 grams of the lowest in the control treatment, which is 13.50 grams. The average weight of the fruit of the highest found in the 731.25 grams of PGPR treatment and lowest in the control treatment fruit weighing 417.50 grams.

ABSTRACT The research was arranged in a randomized block design (RBD), with 10 treatments and 3 replications. To get the active insects pests, net sweepings were done for the flying insects, while other pests were observed directly on the plants. Collecting data of plant damages were made by systematic diagonal lines, except for viruses, census was conducted on each experimental plot. The results of this experiment documented 12 species of insect pests attacking soybean plants. Soybean pest populations were relatively low, except for Aphis glycine that was quite high. In all treatments, plant damage caused by sucking pest Piezodorus sp and Riptortus linearis were relatively low of 1.53 % to 1.94 %; it indicated an insignificant effect to decline the production. Crop damages by virus showed a significant effect. The lowest virus attacks found on compost of 5 tons per ha with 43 plants infected per treatment, the highest virus attack showed on combination of 5 tons compost per ha + inorganic fertilizer + mulch, in which there were 274 infected plants per treatment. Apparently virus attacks gave impact on soybean production. The highest production were documented on treatment of 5 tons compost per ha with production of 0.55 tons per ha, while the lowest production was found on combination of 5 tons compost per ha + inorganic fertilizer + mulch, in which the production was 0.22 tons per ha.

ABSTRACT This research aimed to determine the effects of compost applications on ex-mining lands by using chinese cabbage as indicator. The experiments were conducted at the Faculty of Agriculture greenhouse and the soil and compost analysis were done at the Soil Chemistry and Fertility Laboratory for a duration of two months. The research employed a Completely Randomized Design method with 5 treatments repeated 3 times to get 15 experimental units. The analysis on ex-mining soil revealed that it contained only trace amounts of soil nutrients N, P, and K. The laboratory analysis on the compost sample resulted in a C/N ratio of 11.87 which suggested that the compost was mature and ready to be used. The Analysis of Variance on research data showed that compost applications did not affect plant height between treatments at each weekly observation, and similarly did not affect leaf quantity and fresh weight at harvest time. However, the research found that the compost applications tended to improve plant height, leaf quantity, and fresh weight of plants at harvest time. The minimal effect of compost applications between treatments suggested that the plants did not utilized the nutrients supplied by the compost in their early stages of development. Moreover, it was also suspected that the compost applications had not been sufficient in supplying the soil nutrients needed by the plants to ensure proper growth which ultimately affected the fresh weight of the plants at harvest time. Keywords: compost, ex-mining land

ABSTRACT Improvements to the identification techniques adapted to the latest determination key, requires socialization, so that the farmer can determine which plant pests have damaged many crops and causing losses. This study were conducted to determine species of fruit fly Bactrocera spp. and to determine the population of Bactrocera spp. attacking commodities chili, tomato and pumpkin siam. Research carried out by direct surveys on the area which is the center of the fruit and vegetable crops in Tomohon. Each stretch of the plants fruit vegetable crops of chili, tomato and pumpkin siam was laid trap. The number of traps on each observation plots of vegetables or fruit per plant commodities were 5 (five) traps. The bottle trap was placed in the middle of planting vegetables fruit by a diagonal way. Traps of steiner models made of plastic bottles of 1.5 liters of mineral water and a perforated plastic funnel fitted as entrance fruit flies was used in this experiment. The tool is also equipped with a wire as a binder between the traps and wood enforcement to be put in planting fruit vegetables. Cotton was rolled with a diameter of about 3 cm and then tied with thread and put Methyl Eugenol (ME) of 0.25 ml and Cue-Lure (CL) as much as 0.25 ml by using the syringe and then hung in the middle of the bottle trap.

ABSTRACT The objective of this research was to evaluate the vegetative development in 3 North Sulawesi local rice varieties (Superwin (A), Temo (B) dan Burungan (C)) as a response to the thickness variation of cultivated soil layer combined with irrigation deletion. This research was conducted in the glasshouse using polyvinyl chloride (PVC) column (500 mm height, 125 mm diameter) as pots. The treatments consisted of 3 variations of cultivated soil layer, i.e. 18, 24 and 30 cm and the clay hardpan was placed below each of the cultivated soil layers. The level of irrigated water and the amount of the fertilizer were applied following the method of SRI (System of Rice Intensification). The results showed that reducing the thickness of cultivated soil layer to 18-24 cm saved the water as much as 6.15-8.12 L (29.7-39.2%) per pot compared with 30 cm thickness of soil layer in Burungan. Comparing with the 24 cm soil layer thickness, the treatments of 18 cm thickness saved 6.92 L (23.42%) and 5.77 L (18.32%) water, respectively in Superwin and Temo.

ABSTRACT A plant species can release a toxic compound which can inhibit the growthof other plant species. The success of planting certain tree species, both inside and outside the forest area with agroforestry system can be affected by allelopathy of other plant species. The objective of this research was to study the response of sengon laut (Paraserianthes falcataria (L.) Nielsen) seed germination on cogongrass (Imperata cylindrica L.) leaves and rhizomes allelopathy. The experimental design was a randomized complete design with four replicates. The treatments were leaves and rhizomes extracts of cogongrass, and water as control. The results showed that the extract concentration of 20 % (weight/volume), then the sengon laut seed germination was not affected by the extracts.

ABSTRACT Outdoor spaces are important to sustainable cities because they accommodate outdoor activities and contribute greatly to the quality of urban living.During the last decade, interest in the assessment of thermal comfort has increased because of climate changes and increased heat stress in cities. Greenspaces that provide a pleasurable thermal comfort experience for users effectively improve their quality of livability and productivity. However, current investigations lack a general framework for the use of thermal comfort assessment, such as in making master plan or designing better greenspace. This paper discusses greenspace of Sam Ratulangi University Campus relating to thermal comfort. It provides knowledge of thermal comfort investigation and landscape design review. The results of thermal comfort assessment, among 11 observed plots, only greenspace at FMIPA is categorized as comfortablespot. Greenspaces at FAPET and FEB are not really comfortable, those at BNI and FKM A and FKM B are not comfortable and those at FATEK, FAPERTA, FISIP, FH, FKM A are categorized as very uncomfortable spots. We suggest some options for redesigningof uncomfortable and very uncomfortable greenspace spots.Keywords: greenspace, outdoor, termal comfort
