Abstract

ABSTRACTThe study of the growth of Gyrinops vesteegii (Giil) plant by applying various doses of G-tonic liguid organic fertilizer had been carried out in the Greenhouse of the Faculty of Agriculture, University of Sam Ratulangi Manado.The purpose of this study is to find out the effect of various doses of liguid organic fertilizer on the growth of the Gyrinops vesteegii plant. This study is conducted by using Randomized Complete Block Design ( RCBD) with 5 treatments and 5. Replications each replication consists of one plant. The treatments applied were P1 (Control, without fertilizer), P2 0.125 cc of G – tonic liguid organic fertilizer given every application. P3 0,25 cc, P4 0,375 cc, and P5 0,500 cc. The variables observed were the increase of plant,s height as well as of stalk diameter. The data obtained will be analyzed by using Analisisv of Variance (anova) at 5% level.The result of the study showed that the application of G-tonic liguid organic fertilizer to Gyrinops vesteeglii plant seedling did not have significant effect on the increase of plant,s height and stalk,s diameter. This is due to the liguid organic fertilizer did not have yet effect toward the Gyrinops vesteeglii plant seedling in a period of 35

ABSTRAKThis research aims to know the influence of leaf fertilizers and shade on the growth ofGyrinops verstegii (Gilg) Domke under water stress. This research was conducted in the greenhouse of Faculty of Agriculture, University of Sam Ratulangi Manado, from June to August2013. Spit plot design is used in this research. Shade as main plot consists of two levels,namely: 1 layer of paranet N1 (light intensity ± 40%) and 2 layers of paranet N2 (lightintensity ± 16%). Doses of fertilizer as sub-plot consists of 3 levels: P0 as a control (nofertilizer), P1 0.012 g/plant and P2 0.024 g/plant. The fertilizer was given every week for 2months. The effects of both shading and fertilizer treatments were not significant on plantheight and stem diameter under water stress.Keywords: Gyrinops verstegii, water stress.

ABSTRACTThe Research Anthocephalus growth macrophyllus (Roxb.) Havil) at various doses of compost have been carried out in the greenhouse of Faculty of Agriculture, forestry science courses Unsrat. The purpose of this study was to determine the effect of the growing medium compost on growth Anthocephalus macrophyllus. This study uses a randomized block design (RBD), with five treatments and five replications each test consists of 6 plants. Compost growing media treatment levels given are A control (without fertilizer) B (0.5 kg), C (1kg), D (1.5 kg), E (2kg). variable observed that the increase of plant height, stem diameter increase, in the number of leaves, root volume and dry weight of the plant. This study uses a randomized block design (RBD).The results showed that the growing medium compost significant effect on the growth of high and volume root crop seeds Anthocephalus macrophyllus. And the effect of high growth and volume Anthocephalus best root seedling compost macrophyllus is giving treatment that is as much as 1.5 kg at treatment D.Keyword : Compost, Seed Growth Anthocephalus macrophyllus

Abstract

ABSTRACTThe purpose of this research was to determine the number and species distributionof ebony (Diospyros spp.) at the Animals Rescue Center of Tasikoki. This study wasconducted in North Minahasa Regency, District of Kauditan, Village of Watudambo whichconducted for 6 months, from March to September 2015. Data collcetion was conductedby using the census method, all types of vegetation that resembles the species of ebony(Diospyros spp.) which are located in the area of Animals Rescue Center of Tasikoki wereobserved, which starting from a predetermined point until the entire region was observed.The results of data collection in the field, have been found two species of ebony (Diospyrosspp.), namely Diospyros maritima and Diospyros ebenum with the total of 1864 rods forDiospyros maritima and 63 rods for Diospyros ebenum. To Diospyros maritima wasdivided into four phases of growth, i.e. 1499 at the seedling stage, 249 at stake phase, 98in pole phase, and 18 in tree phase. Most of that four phase of growth, was found in dryand non-flouded areas which adjacent to the coastline in the region. Diospyros ebenum wasdivided into three phases of growth, namely 4 in the seedling phase, 54 in sapling phase,and 5 in poles phase. Most of that three phase of growth also found in dry and non-floadedareas which adjacent to the coastline in the region of Animals Rescue Center of Tasikoki.Keywords: Diospyros spp., species distribution, phase of growth, Animals RescueCenter of Tasisoki.

Abstract

ABSTRACT Gyrinops caudata an agarwood-producing plants are of good quality, so the price on the market also increased tailored to the needs of the present. To meet the demand of the market it is necessary to improve the welfare of farmers cultivation of agarwood and reduce the level of damage to forests from natural forests aloes search uncontrollably. Cultivation of this crop requires the application of techniques and methods that aim to spur growth in order to produce quality results and growth in accordance with the growing age. This study aims to investigate the response of fertilizer given to plants producing agarwood by using the experimental method, the observed data were analyzed using the F-test (variance) to determine the spread of the data and proceed to the t-test to determine the level of difference in the increase in diameter of the two group of plants. Through the analysis of test-f and proceed to the t-test concluded that the treatment that is given in plant with a combination of fertilizer, NPK and added foliar fertilizer (bayfolan) accreting diameter better than combination fertilizers that do not add foliar fertilizer Bayfolan.Key words : Agarwood, Gyrinops caudata, Fertilizers, Bayfolan, Experiment.

Abstract

ABSTRACT Macaca nigra is one of seven species spread on the island of Sulawesi. Macaca nigra has experienced a decline in population due to widespread hunting and habitat loss, so Macaca nigra is now listed as endangered. Knowledge of the home range and population of Macaca nigra in the Manembo nembo Wildlife Reserve is one of the important elements in the management of the Wildlife Sanctuary. The study was conducted in the Manembo-nembo Wildlife Sanctuary. Tomabariri District, Minahasa. The study took place in September 2018. The research method was carried out by observing one Macaca nigra group continuously throughout the day. The results of the study showed that the Macaca nigra group at the study site were 26 individuals. Macaca nigra has a specific home range The population of Macaca nigra observed having roaming rotation only takes 1 day. The Macaca nigra group observed explored an area of 23.36 ha. The trip of the Macaca nigra group in one rotation ranged from 0.28-23.36 ha from the total observations for 14 days and the Macaca nigra group in the Manembo Nembo Wildlife Sanctuary had three sleeping trees and had 7 species of feed plants which became the highest preference was Ficus benjamina and Dracontomelon dao (32.1%). The type of tree is using for sleeping tree is Ficus benjamina, Dracontomelon dao, and Pterocapus indicus.
