Abstract

ABSTRACT  This study aims to identify the behavior of farmers in managing coconut farm in the village of Gosoma, Tobelo district.  Coconut farming in this area is not something new for the community, since it has been done using conventional practices revealing their penetration in the culture in this place. This culture should be adjusted to the farmers? economic needs. This can be a barrier if farmers have limited knowledge and their attitudes are still very traditional.  This research was conducted in the Gosoma village, Tobelo District. Data were collected for three months, from August to October 2014. The data obtained are primary data and secondary data.  Primary data were obtained directly from a survey for farmers involved in managing coconut farming in the village of Gosoma.  The secondary data were  obtained from some government bodies related to this study. The author takes a sample using purposive sampling technique with sample size of 50% of the total population or 60 coconut farmers.  The results show that 1) Farmers still apply  traditional  coconut processing, and still have the tendency to maintain  the heritage. 2) Coconut farmers like coconut farming jobs because they are used to working as farmers.  There are a few who do not  like to be farmers because of occasionally insufficient income in this business. Until now the coconut farmers have not been formally trained, but have learned from practices shown by their ancestors.  They were able to maintain their plantations because of the finances they get from this business. 3) Almost all parts of the coconut tree can be used such as midrib, leaves and shells.  However, the processing or utilization of the waste of palm trees has not been optimally processed.  Some people argued that the waste is useless and worthless. The conclusions of the study are 1) The  farmers in the village of  Gosoma  still apply traditional ways in managing coconut farm. There are four reasons behind this.  Firstly, out of the 60 coconut farmer respondents in the village of Gosoma, there are only 15% who are actively doing family run coconut farming.  Secondly, most the the 60 farmer respondents still rely on the products of their coconut farm. Moreover, for the coconut farmer, agricultural land is everything that makes a reliable source of food, a highly valued property,   and the most important factor for social status. Thirdly, out of the 60 farmer respondents there are 45 respondents who have a very strong will to preserve tradition and social solidarity.   Coconut farming waste is used for food and other daily needs. Coconut tree trunks and palm fronds are used as firewoods in the kitchen. Coconut fiber and shell are usually sold. The coconut shell is sometimes used to heat traditional iron to press clothes.   Key words: farmers? behavior, managing coconut farm, Tobelo

Abstract

ABSTRACT  The research was conducted in Batuputih Recreational Park, North Sulawesi with the aim to inventory plant species and feeding frequency of Sulawesi crested-black macaques (Macaca nigra). A group of macaques was followed continuously starting in the morning at the sleeping tree. Observations were made in 15 minute segments including plant species eaten by alfamale, the main female, and another macaques. Plant species and eaten parts were recorded. The results showed that there are 22 species of food plants eaten by the Sulawesi crested- black macaques in Batuputih Recreational Park. The highest eating frquency is kayu sirih (Piper aduncum), Nantu (Palaquium quercifolium), coro (Ficus variegata), aren (Arenga pinata), kelapa (Cocos nucifera), and Seho yaki (Caryota mitis). The macaques ate fruits, shoots and young leaves. Alfamale feed pattern followed almost aligned by the main female and the other macaques except for Cocos nucifera, Dracontomelon dao, Eugenia malaccensis and Morinda bracteata. Exceptions of feeding pattern is that the other macaques have a very high preference in these species in comparison to alfamale and the main female. Feeding range of the macaques were more frequently in shrub land than the secondary forests.  Keywords: Sulawesi crested-black macaques, Fodder Plant Species, Home Range.

Abstract

ABSTRACT Chrysanthemum or Chrysanthemum marifolium Ramat is one of the types of cut flowers have bright market prospects. As one of the types of ornamental plants, dubbed "King of Cut Flowers" besides having a shape and color which is very interesting, this plant has already started a lot of fans. Diseases that attack chrysanthemum eg rust disease caused by the fungus Puccinia sp. Damage results because this rust disease attacks especially on susceptible plants can reach 100% or crop failure. Rust diseases Puccinia sp. This allegedly carried on planting material (seeds) that has spread to many locations planting chrysanthemums. Tomohon is a center for the production of ornamental plants, especially chrysanthemum in North Sulawesi. Preliminary observations in planting chrysanthemums in Tomohon showed white rust disease. The purpose of this study was to look at and examine the effectiveness of microorganisms antagonistic Trichoderma sp., Pseudomonas fluorescens and Paenibacillus polymyxa to disease chrysanthemum white rust on research was conducted by using the method of randomized block design with four treatments namely A control treatment without application of antagonistic microorganisms, treatment B the application of microorganisms antagonistic Trichoderma sp., the treatment C with application of microorganisms antagonistic P. fluorescens and treatment D with application of microorganisms P. polymyxa. This treatment was repeated 5 times. Rating affected leaves using index calculation disease (severity). The variables measured are severity of affected leaves, leaf number and plant height. The results showed that of some microorganisms are used, equally effective in controlling the disease chrysanthemum white rust is antagonistic microorganism Trichoderma sp. with the value of the average severity of the last observation was 17.71%, followed by P. polymyxa with the average value of 26.78% last severity. Furthermore, the third treatment antagonistic microorganisms do not give effect to the number of leaves and plant height.  Keyword: Chrysanthemum, P. horiana, Trichoderma sp., P. fluorescens, P. polymyxa

Abstract

ABSTRACT This study aims to determine the pest populations of P. xylostella in cabbage plants in the Paslaten village East Tomohon Tomohon sub district. This research was carried out by making a demonstration plot with three sub-plots. The results showed that the population of P. xylostella larval instars three and four on cabbage in the Village Paslaten East Tomohon Tomohon sub district in the rainy season ranged from 0 to 0.73 individual crop. P. xylostella larvae population is low from the first to the last observation. The low pest populations of P. xylostella at the time of the research is influenced by three factors: the first factor of climate especially rainfall with high intensity, the second factor D. eucerophaga parasitism natural enemies, and the third is a competition looking for food with other species of pests. Keywords: population, P. xylostella, Cabbage

Abstract   Rante Lembang, V.W., W. Tilaar, dan T.M. Frans, 2015. The Ecological Potential, Dispersion Patterns and Utilization Patterns of Natural Fiber in The Limited Production Forest (LPF) of Sinonsayang Mount, North Sulawesi   In Province of North Sulawesi, natural fiber plants (bast plant) were found scattered either in primary forests area or secondary forests area, including in the limited production forest area (LPF) of  Sinonsayang Mount. The information regards to the ecological potential, dispersion pattern, and the pattern of utilization in the region is not yet known with certainty, it is therefore need to be observed. The aim of the research was to describe the ecological potential, dispersion patterns, and the utilization patterns of natural fibers within the limited production forest (LPF) of Sinonsayang Mount, North Sulawesi. This was conducted for 2 (two) months in the limited production forest (LPF) of Sinonsayang Mount, particularly, in the area which have been used by the community as a dry land farming and the shrubs overgrown area (± 500 acres).  The inventory method was used in this research, in which the plots were placed randomized using random sampling pattern (simple random sampling). The results shows, there were five (5) types of natural fibers found in the inventory field, namely: bamboo, pandanus, cotton, agave, and rosella. The bamboo population per hectare was higher than other types of natural fibers, amounting to 19 ≤ individual / ha ≤ 21, while the rosella type was found as the smallest population, about 0.08 ≤ individual / ha ≤ 0.09.. The frequency value, and the percentage value of each type of bamboo natural fiber was 0.73, and 95.66%, respectively, while the frequency value and the percentage value of each type of rosella natural fiber was the lowest, that is 0.02 and 0.04%, respectively. The dispersion pattern bamboo natural fiber types were randomly spreaded in the region, while the other types of natural fibers (pandanus, cotton, agave, and rosella) were spreaded out in groups. As for of the 5 (five) natural fibers types that found, there is only 3 types of natural fiber used by the public, viz: bamboo, pandanus, and cotton. The natural 3  fiber of bamboo was the most widely used by the community, both for personal consumption and for sale to the village market, and the market district.  There were 11 forms of utilization of natural bamboo fiber by the communities surrounding the forest area for the purposes, consist of: making walls of house / cottage garden, fence, stairs, livestock pen, nesting of laying hen, ethanol refining installation of aren, to build furnace wall, medium to cook fish / pie, rice winnower, groceries bamboo shoots (young shoots), and for lalandangan. Meanwhile, the utilization of natural fibers of pandan and cotton were still limited for their own consumption as a raw material for making mats, pillows, and the fuse of the bottle lights.  Keywords: Natural fibers, ecological potential, dispersion patterns, and         utilization patterns
