Abstract

ABSTRACTWoman Participation in the Implementation of Agroforestry in the Village of Warembungan, sub-District of PinelengIt is well known that woman has certain participation level varied from household activities to a broader sense such as participation in household income generating. With the exception to woman monthly income that valued in rupiahs, it is very rarely that contribution value of woman participation is quantified. This is happened to all woman community at city and village level as well. At village level, where farming effort ast as prime mover of household economy, it is estimated that the smaller the number of family member, the higher the participation level of woman contribution in farming activities. Warembungan Village, Subdistrict Pineleng is a sample of village where the farming effort in form of agroforestry applied to fulfill the family needs. It is therefore, woman participation level in order to establish its contribution value needs to be quantified. This study aimed to describe the level of woman participation in agroforestry activities, and to further analyze the relation between woman participation and socio-economy factors. Research was conducted in Warembungan Village, subdistrict Pineleng using structured questioner survey analyzed descriptively and then using Chi-square (x2) to see the relation mentioned above. Results showed that the level of participation of women classified as medium category with a percentage of 80%, The female participation rates no significant correlation with socio-economic factors,Keywords: woman participation, Warembungan, socio-economy factors

Abstract

ABSTRACTRed fruit (Pandanus conoideus Lamk) is an endemic plant of Papua that can be developed as one of the food coloring sources of Indonesia. Other than that, red fruit also is a source of natural dyes, because it contains active compounds such as α-carotene, β-carotene, β-kriptosantin, and α-tocopherol, and unsaturated fatty acids, especially oleic acid, linoleic and palmitoleic. Red fruit contains carotenoids that produce the orange-red pigment. The purpose of this research is to analyze the effect of concentration of ethanol on the extraction of red fruit as a natural coloring food and also to analyze the level of applying acceptance of this coloring products to the pudding and layer cake. The method is implememted the Complete Random Design (RAL) with differences concentration of ethanol. The results showed that 70% concentration of etanol yield 0,260 of total carotenoids, 2,856 of color intensity, color stability to light ranges from 0.263 to 0.689. The concentration of 60% ethanol yield of total 0,171 carotenoids, 2,693 color intensity and color stability to light ranges from 0,602 to 0,657. Sensory testing of the extraction of red fruit as a natural dyes to the flavor, aroma, and color that preferred by the panelists is treated with 70% concentration of ethanol.

Abstract

ABSTRACTCoconut plantation areas in Indonesia, specifically in North Sulawesi by the owners are tendto use monocultural pattern with only one product, copra. Efficiency in using growing spaceand certain planting pattern in form of agroforestry and its combination will give reciprocalbenefits, i.e. the cleanness of coconut planting area could be maintained with a possibility ofincreasing in coconut product, and economical benefits by utilizing of the unused growingspace on the lower space of coconut plantation area. If the economical benefits could bequantified, application of agroforestry pattern could be practiced to a wider area. Applicationof agroforestry pattern between coconut trees (Cocos nucifera) and taro (Colocasia esculentaL) by farmers who work on coconut plantation area is one of the agroforestry pattern that hasbeen used in Klabat Village, North Minahasa Regency. Lacking in knowledge of economicalvalue of the agroforestry pattern applied is a motivation why this reseach was done. Theaimed of this research was to analyze farming revenue based on agroforestry patternapplication between coconut and taro at Klabat Village, North Minahasa Regency.Questionnaire and interview were employed to collect required data and information using 30purposive respondents. This concluded that planting of both crops in combination resulted inhigher revenues than that of monocultural planting.Key words: agroforestry, Klabat village, farming revenue
