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

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    This research was done to study the increment of Gyrinops versteegii on lands with different levels of ground water depth, a shallow groundwater depth (45-50 cm) at A location and a deep groundwater depth (90-98 cm) at B location. This study used comparative method and purposive sampling. Variables observed were the increase in trunk diameter and free- branch heigtht of Gyrinops. The number of plant sample used was 6 (six) plants, three (3) plants for each location. The measurement of trunk diameter was done, using a measuring tape, at the base of the stem or at 30 cm from the ground. Free branch height was measured from the base of the stem up to the height of the first branch. These observations were done once a month for a year. The results showed that the growth of plants in two locations had differences in trunk diameter and free-branch height from the first month until the last month of observation. The average increments of trunk diameter and free-branch height in the B location were greater than in the A location. Keywords: increment, the ground water  level, Gyrinops versteegii

Abstract

ABSTRACT Information on agricultural machinery and equipment is required for the development of agricultural technology in Indonesia. Although Indonesia is known as an agricultural country, its agricultural technology is considered less developed compared to many other non-agricultural countries. One reason behind this is the dissemination of information regarding agricultural machinery and equipment still believed asunstructured and fragmented. Advancement in information and communication technology has made easiness for people in accessing information. Android operating system is gaining more and more popularity and its userin Indonesia is growingfast. This research aims to develop an Android based practical learning application on agricultural machinery and equipment. This research was carried out during the month of April 2015 to June 2015 and the resulted application was successfully installed in Android as a 1.8 Mb APK file format. The application was tested on CPU emulator and Andromax smartphone followed by a survey to 16 respondents using questionnaire having 10 questions in it (5 questions for application and 5 other questions for content of application). The respondents, who marked each question with 1=very disagree; 2=disagree; 3=neutral; 4=agree; 5=very agree, consist of 10 university students, 3 university lecturers, 1 representing farmer, 1 consultant in agricultural machinery and equipment, and 1 representingcommon people. Results of the test conclude that this Android application can be implemented as information media to improve awareness of public and university students regarding agricultural machinery and equipment in a quicker and a more efficient way. The application can also help disseminating information regarding agricultural machinery and equipment in a more variety way in order to support the development of agricultural technology in Indonesia.

Abstract

ABSTRACT Talawaan watershed is one of the most important watershed in North Minahasa Regency. Erossion in the Talawaan watershed results in decreasing land resource quality caused by both natural and human activities. This research aims to study the erosion hazard level in Talawaan watershed. Method to calculate erosion rate is based on USLE equation (Wischmeir and Smith, 1978) utilizing Geographic Information Systems (GIS). Result shows that the erossion hazard levels in Talawaan Watershed were “very light” 2.791,56 ha (21,49%), “light” 4.019,46 ha (30,94%), “medium” 3.127,86 ha (24,08%), “heavy” 2.521,79 ha (19,41%), and “very heavy” 528,88 ha (4,07%). Talawaan watershed has an average erosion rate of 60.53 tonnes/ha/year which is “medium” erosion hazard level. The results of this study may be used to a better management plan of Talawaan watershed. Keywords: TBE, GIS, USLE, DAS Talawaan.
