ABSTRACT  The traditional agroforestry homegarden in the village when judging from the vegetation composition it have interesting characteristics. Village homegarden ecosystems have a very diverse ecosystem service function and play an important role in the lives of rural communities. The purpose of this research is to know the diversity of plant species in agroforestry homegarden in Warembungan Village. The method used in this research is the interview method by using questionnaires as a means of collecting primary data and secondary data and direct field observation Based on the results of research in Warembungan Village, Pineleng District found 53 species of homegarden plants. The diversity of plant species consists of 24 families. The diversity of plant species consists of 24 families.

Abstract

ABSTRACT  Colletotrichum capsici is one of the fungi that can cause anthracnose disease in chili plants. Trichoderma sp. is an antagonistic fungus that has the potential to control anthracnose disease. This study aims to determine the growth and development of the fungus Trichoderma sp. and Colletotrichum capsici pathogenic fungi as well as the percentage of inhibition of Trichoderma sp. fungus. against the Colletotrichum capsici fungus. Testing using dual culture method on Potato Dextrose Agar media to know the percentage of inhibition.The results of this study showed that the colony of Trichoderma sp. able to inhibit the growth of Colletotrichum capsici fungal colonies with an average percentage of 2.82% inhibition on the third day after inoculation; 70.28% on the fourth day after inoculation and 100% on the fifth day after inoculation.  Keywords: Percentage, Colletotrichum capsici, Anthracnose

Abstract

ABSTRACT  Mahogany tree besides capturing carbon for its natural growth, it can be hypotezised that the tree has a capability to reduce CO2, heat energy and other pollutant contents that released to the air.  Total carbon captured by the mahagony tree, then can be estimated quantitavely in form of biomass.  The aims of this research were to calculate biomass content on mahagony trees and to estimate the biomass characters on each part of the trees.  The researh was done in UNSRAT area from June to July 2017 by Cencus Method.  The data were analysed by using Allometric Equations developed to calculate biomass content of mahogany tree.  The result showed that from the 313 trees, the total biomass was 304,052.99 kg.  It was characterized by the biomass content on tree trunks was 5 %, stems 73 %, branches 17 %, branchlets 2 %, and on leaves 3 %. These imply that the mahagony tree can be planted to over released pollutant area in order to reduce the CO2, heat energy and other pollutant contents.  Keywords : Mahogany Tree, carbon, biomass, UNSRAT

Abstract

ABSTRACT  The research aims to identify the quantity of demand and marketing outlets bamboo constuction in the bamboo sales outlets in Kinilow urban village. The research used interview method with the tools of the questionnaire for 4 respondents. The result of research showed that in general, the quantity of demand basically very fluctuated. The size demand of bamboo construction was difficult to set, but stock of bamboo keep provided all the time. Estimated within a week of bamboo construction available approximately as much as 1000 tips. The quantity of bamboo construction demands each month ranges from 750 to 1000 tips. Construction bamboo producers that was too small had very simple marketing outlets. There were 2 marketing outlets, (1) the farmers (producers) sold to consumers directly. (2) the farmers (producers) sold to collectors and then the collectors sold to consumers.  Keywords : Bamboo Construction, Demand, Marketing Outlets, Kinilow urban village

Abstract

ABSTRACT   This study aims to describe the biophysical and socio-economic conditions of Mount Mahawoe Protected Forest area and examine the strategy of the development of Mount Mahawoe Protected Forest area into the Great Forest Park area in terms of policy, institutional and potential of the area.This research was conducted by using survey method and interview to formal and informal parties by using open question questionnaire. Based on the SWOT analysis, there are 20 (two pulse strategies) that can be taken as an alternative strategy in achieving the objectives of Mahawoe Mountain forest area development into Tahura such as maintaining community commitment and participation, developing the role of NGOs and community leaders around the Mahawoe Mountain area in forest area development activities, establishes priority target locations that directly impact the protection of the hydrological system, develops species of economic and ecological value, builds stakeholder participation and cooperation in controlling the sale and purchase of land in the Mount Mahawoe protected forest area.     Keywords : Mount Mahawoe, Protected Forest, and Tahura.

Abstract

ABSTRACT  Temporal variation in canopy phenology of Mahogany Tree (Swietenia macrophylla King) is a general pnenomenon that happened in field plantations.  Seasonal timing in case of early - late shoot emergence, leaf shading, flower emergence, and fruit maturation are life cycle events that can be used to predict flowering patterns and reproductive success.  Mahogany tree vegetation in UNSRAT area is one of isolated population that interested to be considered.    The aims of this research was to study temporal variation in canopy phenology of Mahogany Tree.  The researh was done by Cencus Method from May to June 2017.  The data were analysed by using descriptive statistics.  The result showed that from the 346 tree visually observed, there are 134 trees have new shoot emergence,  189 trees have young leaves, 26 trees have yellow color leaves for shading, 4 trees in stage of flowering emergence, 82 trees in fruiting stage, 6 trees has fallen fruits, and 1 tree has contain young fruit.  These imply that the canopy phenology of mahagony tree has high variation in response to its ambient condition.  Keywords : Mahogany Tree, canopy phenology, temporal variation, seasonal timing, UNSRAT

Abstract

ABSTRACT   Rice is the second staple supplies in Jayawijaya Regency of Papua product beside Sweet potato. The area of rice plant is 250 ha, with production of 655 tons (BPS data from the Department of Agriculture of Food Crops and Horticulture of Papua Province 2014). The total area of Jayawijaya Regency is 13,925.31 km2 which is administratively divided into 40 districts with 4  Kelurahan, and 328 Villages. The Population area 241. 280 inhabitants. Most of the people live on slope of the hills  whith are difficult to reach and are of temhisby long dryness. The estimation of the evapotranspiration in this research uses a plant simulation model. The purpose of this simulation model has advantages, among others, does not require a long time to utilize the results and cost efficient in terms of cost. This study aims to estimate the monthly evapotranspiration of wetland rice crops in Jayawijaya Regency Papua Province by using shierary rice.Ve2 2, 1. The results of research can be used as a tool for cultivating rice crops especially for water management. The growth model is a simple representation of the plant growth system described in the mathematical model and analyzed statistically. The advantages are derived from the using of model simulations, that such as can shorten the time to predict the potential of crop production.  Keywords: Evapotranspiration estimation of field and model results

Abstract

ABSTRACT Macrocephalon maleo S. Muller, 1846, an endemic bird species to Sulawesi and classified as Endangered, is now used as flagship species for conservation purpose. Conversion of its habitat, habitat loss and fragmentation, and degraded habitat quality are several suspected factors that impacted the bird population. Its habitat in Tanjung Binerean at Mataindo Village, South Bolaang Mongondow Regency is now suspected to be declined in form of habitat quality. The aims of this research was to analyze Maleo Bird's habitat based on tree structure and composition. The researh was done in Tanjung Binerean at Mataindo Village, South Bolaang Mongondow Regency in June 2017 by Systematic Strip Method. Data were collected from three transects on 25 plots, and were analysed its relative frequency distribution. The result showed that there were 56 tree species that dominated by Alianthus integrifolia (21,23 %), Cananga odorata (12,16 %), Canarium asperum (8,82 %), and Ficus septica (8,32 %). This imply that the Maleo's habitat is now in disturbed condition with the presence of F. septica.Keywords : Macrocephalon maleo, South Bolaang Mongondow Regency, habitat, flagship species, Ficus septica
