Abstract

ABSTRACT One of the harmful insects in maize is the wanderer Grasshopper (Locusta migratoria L.). Grasshopper wanderer often found the area under maize cultivation . Grasshopper wanderer, both young (nymphs) and old, eating the leaves of corn plants, thereby reducing the surface area of leaves. Adult grasshoppers usually eat the leaf edges , while his nymph takes in between bones , causing leaves holes in the leaves. If this locust attack in a high number of population, the leaves of corn plants that are attacked will be devoured. In connection with the matter, has done research on  grasshopper  population  density  wanderer  on  corn  in  the  Village  Banana  Padang  Pauh subdistrict which aims to determine the wanderer grasshopper population densities on corn plants in Padang Pauh subdistrict Banana Village. This study was conducted in September-October 2013, with the method sweep (sweeping) is a way to swing a grasshopper inseknet existing wanderer on corn which is used as a place of research. Field sampling conducted on maize age of 1 month and2 months after planting by using inseknet and hands. Widely used as a research area of 20x20 m. Sampling was conducted at five points with a size of 3x3 m at each point. Physical environmental factors measured are temperature and humidity. From the research that has been conducted in the village of Padang Pauh subdistrict Bananas can be concluded that the grasshopper population density wanderer in maize of different ages 1 month to 2 months of age. Wanderer grasshopper populations on corn gained as much as 1 month of age 0.7 individuals/m² (0.3 nymphs and 0.4 imago), population density is lower than in maize aged 2 months gained as much as 1.8 individuals/m² (0,7 nymphs and 1.1 imago).

Abstract

Insects are very important  role in the ecosystem. Among these roles are: herbivory, predation, parasitism, decomposition, pollination, and so on. In addition the role of insects have also been used as an indicator species. Several recent studies indicate that insects exhibit responses that indicate the level of damage to forest habitats. To see how far the influence of the change will be seen flying insect diversity at both locations using window traps. This method was chosen because it will see the role of the flying insects that can be used as indicators of land use change on stratification of the tree which is in both locations expected goal in this study were 1) to determine the level of insect diversity at both forest sites 2) To determine the effect of changes in the forest insect conditions in each forest stratification. From this reseach it was found that the highest density levels are apparently heterogeneous forest there are 29 families 41 species and 119 individuals from arrest (day and night), while 22 families monocidture forest with 32 species and 98 individuals for whom the level of diversity among heterogeneous forest monoculture forests in monoculture forests range 2.14 <H <2.84. While in heterogeneous forests ranged from 2 <H <3 and the third similaty index was not significantly different strata.

Abstract

This service aims to provide information so that farmers can utilize and apply liquid organic fertilizer from vegetable waste (MOL) to rice plants in the village of Cot Darat, Sama Tiga District, West Aceh Regency. The method used to achieve these objectives is through counseling using participatory and on-site practice. The stages of its implementation are through counseling methods in the form of material exposure on vegetable waste MOL, discussion of farmer groups on site, training in processing organic waste into biocomposers together with farmer groups. The results of this service show that the level of knowledge and understanding of technology for processing vegetable waste into organic fertilizer can be absorbed (controlled) by rice farmers. All members of the group consist of various ages ranging from 30 to 50 years. One indicator in determining work productivity in conducting business development is the age level, where the age of farmers who are relatively young is stronger, work smart, easy to accept new innovations.

Abstract

Seeds are mature ovules. One or more of the ovaries formed in the legume, but never more than one seed formed in the ovaries of monocots. Each ripe seed always consists of at least two parts, namely: (1) Embryo, (2) Seed coat (Seed coat or testa). Embryo is formed or derived from fertilized eggs (zygote) by undergoing cell division in the embryo sac. Seed coat is formed from the integument (one or more) of the ovules. In legumes generally there are two layers of seed coat. Every very young and growing seed always consists of three parts: (1) Embryo, (2) seed coat, (3) Endosperm. Endosperm is a storage food storage network which is absorbed by the embryo before or during seed germination and is always present in very young seeds. Polyembryonics is the presence of more than one embryo in one seed, but these embryos do not always mature or mature, remain undeveloped or degenerate. The purpose of this research is to study the germination of one seed that has more than one embryo and to determine the growth of seedlings from polyembryonic seeds. The results showed that the highest plant growth (plant height, number of leaves, fresh weight and dry weight of orange seeds) was found in orange seeds that had 1 embryo compared to orange seeds which had 2 and 3 embryos. Seed germination and growth is strongly influenced by the amount of food reserves stored in seeds (Magagula and Ossom 2011 in Hasnah M, 2013). Keywords: Citrus Seed, Polyembrioni, Seed Viability
