ABSTRACTLeydia Esther Rauw. Comparative Advantage of Rice Farming with Moved Planting Techniques And Direct Seed Planting Techniques in North Dumoga Bolaang Mongondow Regency (under guidance of Charles R. Ngangi, as Chairman, Eyverson Ruauw and Ribka M. Kumaat as Members).The objective of this research is to determine the difference advantage with moved planting technique and direct seed planting technique in North Dumoga Bolaang Mongondow Regency.Methods of data collection was the survey method. The data collected consisted of primary data and secondary data. Primary data is data obtained from direct observation and interviews with the respondents based on a list of questions (koesioner), while the secondary data obtained from the relevant agencies and district offices in North Dumoga Farmer Water User Association. The population is all rice farmers consisting of 40 percent of the farmers who use the moved planting system and 60 percent of farmers using direct seed planting then randomly drawn sample (simple random sampling). For farmers with moved planting system was 15 responden and farmers with direct seed plants system was 15 responden.The results showed that there is a difference between the profit of moved planting technique and direct seed planting technique. Advantages of direct seed planting technique is greater than moved planting techniques although the cost of productivity and input factor of both planting techniques were not significantly different. Furthermore the largest cost used on rice paddy farming was labor costs.

This study was carried out for 4 months ie June to September 2012 This study aims to determine the type and insect populations found in plant seeds Jabon red.Total seed used for this study were 80 seedlings. Planting in polybags done manually which makes the planting hole as deep as 7-10 cm by hand, and then the seeds are planted in the hole until the roots are embedded. This study uses a red seed Jabon 3 months old in the nursery area of the Faculty of Agriculture, University of Sam Ratulangi. One month after the first was in the nursery area, remove the seeds and place it in an open area. Seeds are4placed one by one on a regular basis with a distance of 20 x 30 cm. Insects were collected in a bottle found 70% alcohol for identification. Sampling was conducted in the morning (06:00 to 08:00 hours) and afternoon (Jam 4:00 p.m. to 6:00 p.m.) using insect nets mainly on the type of insect that is active and catching fly directly use an aspirator to the non-flying insects. Insects were collected in bottles containing 70% alcohol to be identified in the laboratory. Observations were made on all samples of plants and sampling was performed five times with intervals of once a week.Insects were found to be separated according to its kind, and then identified. Samples of insects were identified to family level using a library Anonymous, 2011b; Myers., Et al, 2014; Lovett G, 2014.The results showed that insects found in red Jabon plant nursery consists of 4 orders, namely: (1) the Order Hymenoptera (Family Cynipidae, Sphecidae, Formicidae); (2) Order Coleptera (Family Scarabaidae); (3) Order Odonata (Libellulidae Family), and (4) Order Homoptera (Family Aphididae) and Family Pseudococcidae.

North Sulawesi is a region that has a large planting vegetables in the east of Indonesia. Cabbage crop harvested area of approximately 1,614 ha, with an average production of 17.25 tonnes per ha. The low production of cabbage in North Sulawesi caused by farming system which is still conventional and the presence of pests especially Plutella xylostella and Crocidolomia binotalis. The study aims to determine the percentage of the population and parasitization of the parasitoid Diadegma semiclausum in District Modoinding. The experiment was conducted in the South Minahasa Modoinding. Implementation of the study lasted for six months, start from July to December 2013, the research using survey method conducted on cabbage and other Brassicaceae plant at Modoinding District of South Minahasa Regency. Criteria for the location of the sample is the presence or type of cabbage and other Brassicaceae. Materials and tools used in this research are larvae and pupae of Plutella xylostella, Brassicaceae plants, sample bottles, bottle collection of 70% alcohol, tweezers, scissors, cutter, aqua glass, asahi cloth, rubber bands, "hand counter" and "loupe" , as well a stationery. The observation of parasitoid parasitization highest percentage found in the village of Lineleyan which reached 25.23%, then the Kakenturan Village respectively 17.40%, 1.83% Pelelon, Sinisir 1.05%, 0.93% and Mokobang Wulurmaatus 0.59%. Results sweeping using insect nets on cabbage and other Brasicaceae found that the highest population in the village of D. semiclausum Lineleyan (25, 42 individuals), and then successively Kakenturan Village (19.08 individuals), Palelon village (4.75 individuals), Sinisir village (4.50 individuals), Wulurmaatus village (4.08 individuals), and the Mokobang village (2.66 individuals).Keywords: Plant cabbage,Plutella xylostella and Diadegma semiclausum

It means that the corn commodity was efficient and had both competitive advantage and comparative advantage. Two indicators for measure competitiveness were 1) Private Cost Ratio (PCR) show that the corn farmer’s is more competitive because PCR < 1, and 2) Domestic Resources Cost Ratio (DRCR) show that the corn commodity has comparative advantage because DRCR < 1. It means that the corn commodity according to financial analysis was efficient and has greater potency in international trade.
