This objective of the study is to identify the type of insect pestof 10 soybean varieties. The study used descriptive method with field observation technique, whichthen continued by deviation standard measurement. The data were analysed in tabulation, while the insects pest were identified by using insect manual book. The variable of observation were insect pest type, the forms of damaged, the weight of full and empty pod, the number of trunk, fresh weight, dry weight and plant height. The result shows that there are 8 types of main insect pest of soybean such as Ophiomya phaseoli, Lamprosema indicate, Chryzodeixis calcites, Phaedonia inclusa, Spodoptera litura, Nezara viridula, Riptortus linearis and Phiezodorus hybneri. Ophiomya phaseoli is the most insects found in the soybean plants for about 151, following by Riptortus linearis for about 52 and Phiezodorus hybneri for about 32. Among the 10 soybean varieties, Grobogan, Wilis and Kaba were found to be resistant to the pod borer insects pest while varieties resisted to the stem borerinsect pest were Grobodan, Prafi and Kaba. The highest productivity resulted from Cikuray and Anjasmoron which still attacked by the insects.

The study aimed to identify the presence and the population of insect pest to the cultivation of highest productivity soybean. The study designed in randomized block design with the treatments are 6 varieties of soybean such as Anjasmoro (V1), Burangrang (V2), Grobogan (V3), Rajabasa (V4), Detam-1 (V5) and local variety (V6). The data were statistically analyzed and further tested by Duncan (DMRT). The result showed that Ophiomyia phaseoli, Lamprosema indicata, Nezara virudula, Riptortus lineavis, and Etiella zinckenella were the main insects pest found in the 6 varieties tested. Analysis of variance showed that the majority of pest insect populations did not differ between the varieties tested, except for observations at 4 and 5 weeks after planting. The population of beetles mostly found at 11 weeks after planting. The population of insect pest at Anjasmoro variety relatively low compared to other varieties. All tested varieties can be used to increase the productivity of soybean, especially Anjasmoro variety, but the presence of Lamprosema indicata need to be aware at 4 to 5 weeks after planting especially for Detam-1 and Rajabasa varieties.

Agricultural production in Manokwari in 2007 showed that production duku reached an average production of 58.8 kw / ha (BPS Manokwari, 2008). Duku is one of horticultural products are susceptible to damage during storage. This study aims to assess the use of calcium chloride in an effort to extend the shelf life of fresh duku. The method used in this study is the experimental method with laboratory observation techniques. The study consisted of three treatments, namely: (1) control (duku not soaked), (2) treatment duku immersion in a solution of 3% CaCl2, and (3) treatment duku immersion in a solution of 6% CaCl2. The parameters observed weight of the fruit, the appearance of the fruit, the amount of production of carbon dioxide (CO2), and total dissolved solids. Giving the treatment of calcium chloride (CaCl2) can only inhibit the respiration rate and the rate of weight loss fruit, whereas for the other parameters do not provide satisfactory results. CaCl2 application method by immersion was not suitable to be applied on duku because it will trigger the growth of fungi that become shorter shelf-life than without CaCl2 treatment.
