Abstract

ABSTRACTThe tomato Plant (Lycopersicum esculentum Mill.) is an important horticultural plant and classified as the second most important vegetable after the potato. This research’s purpose is to know what insect species and their populations that are associated to tomatoes in their generative phase, which use organic and non-organic fertilizer, in the village of Tonsewer, Tompaso II district. This research is hoped to give information about the species and population of insects that are associated to tomatoes in their generative phase, which use organic and non-organic fertilizer, and thus become a reference for decisions on controlling. This research was done in fields at Tonsewer village, and insect identification was done in the Entomology Laboratory of Pest and Plant Disease Program. The research was done through surveys and samples were collected by swiping a dragnet in a double swing five times. The result of this research showed that tomato plants using organic fertilizer was associated with 5 insect orders, such as : Hemiptera ; Diptera ; Hymenoptera ; Lepidoptera ; Thysanoptera. Meanwhile, the insects in tomato plants using non-organic fertilizer were classified in 6 orders, such as Hemiptera ; Diptera ; Hymenoptera ; Lepidoptera ; Thysanoptera ; Coleoptera. The highest population of insects in tomato plants using organic fertilizer was Hemiptera (Family Miridae: Nesidiocoris tenuis) with 115 individuals, and the lowest population was Lepidoptera (Family Pyralidae : Diaphania indica), with 2 individuals. The highest population of insects in tomato plants using non-organic fertilizer was Hemiptera (Family Miridae : Nesidiocoris tenuis), with 125 individuals, and the lowest population was Lepidoptera (Family Hesperiidae : Erhionata thrax), with 1 individual.Keyword: tomato plant, organic fertilizer, non-organic fertilizer, insect species, insect population

Abstract

ABSTRACTIncreasing the number of residents in North Sulawesi during the last three years from 2009 to 2011 led to increasing demand for rice as well. On the other hand, the production of rice in this area is not self-sufficient, so the government had to import rice to overcome the shortage of rice. The objective of this research is to identify and analyze the factors that affect the import of rice in North Sulawesi.The experiment was conducted from June to December 2013 by using secondary data obtained from the Central Bureau of Statistics, Bank Indonesia, North Sulawesi Province Food Security Agency and North Sulawesi Province Agriculture and Livestock Department in the form of a time series data in 2002-2011 period. Analysis of data use multiple linear regression methods with SPSS Statistics program version 20.Results showed that 86.5 percent of rice imports was significantly affected by the production of rice (27.8 percent significance level), consumption of the population (3.7 percent significance level), the stock of rice (4.5 percent significance level) and exchange rate (15.3 percent percent significance level), therefore it can be concluded that the increasing of rice production and rice stocks in North Sulawesi as well as an increasing in the exchange rate decreases imports of rice in North Sulawesi while the increasing consumption of the population of North Sulawesi increases imports of rice.

ABSTRACTGaharu contains damar wangi from the mastic tree on a part of gaharu-producer trees that accurs naturally and have died due to a fungal infection that accurs naturally or artificially. The purpose of this study was to analyze the effect of frequency method Randomized Complete Design (CRD), with 5 treatment and 5 replications. A treatment without fertilizer, B treatment (application of fertilizer once a week, which is on Saturday, C treatment (twice a week, which are on Saturday and Tuesday, D treatment (3 times a week, which are on Saturday, Tuesday and thursday and E treatment (4 times a week, which are on Saturday, Monday, Wednesday, Friday. Planting medium used in this study is a mixture of soil, sand and chicken manure in the ratio 1:1:1 by volume. Variables measured were plant’s height, stem’s diameter and number of leaves. The results showed that the application of leaf fertilizer Gandasil D on Gyrinops versteegi seedi deliver tangible results in plants height. D treatment (application of fertilizer 3 times a week) showed good results in plant compared with other treatment.Keywords : Gyrinops caudata, Agarwood, foliar fertilizer Gandasil D
