Publisher : Balai Penerapan Standar Instrumen Lingkungan Hidup dan Kehutanan (BPPLHK)Manado

In the forest economics literature, Faustmann formula is highly adopted for profit maximization problem in forest management, mostly in plantation forest. Stylized models of Faustmann formula to be applied in selective logging regime have also been studied extensively in multi-age and multi-species forest. In general, natural forest managers in Indonesia have not adopted the Faustmann formula in their management decisions. Sustainability aspect in natural forest management is applied based on silvicultural consideration, i.e. measuring residual stand that is able to be harvested in the next cutting cycle. This study aims to analyze the application of Faustmann formula in the current selective logging regime in Indonesia (i.e. TPTI), so that the natural forest managers may gain maximum profit and sustainable. This study is a qualitative research based on literature review. The results of this study show that under deterministic growth model (i.e. matrix transition model) and robust damage model (i.e. transition matrix with different damage proportions on each species and diameter class), the Faustmann formula can be applied for selective Logging regime in Indonesia.Keywords: Faustmann formula, selective logging, natural forest, Indonesia

Some people still thinks that bamboo has a low economic value. Many bamboo plants in the community are removed or replaced with other commodities. Sukaharja Village in Ciamis Regency is one of the centers that produce of bamboo. The community feels the economic benefits of the existence of the bamboo, so the existence of bamboo plants is still sustained. Bamboo management in Sukaharja Village can be used as a learning for bamboo farmers in other places. The study aims to determine the potential of agroforestry bamboo in Sukaharja Village. Potency of bamboo was collected by survey method. The observation plot was made as many as 39 plots. Vegetation observation and measurement was done by census (100 %) in all selected land area so that all types of compiler can be known. Parameters recorded/measured were bamboo species, number of clumps, number of tillers, number of young stems, number of old stems, stem height and stem circumference. Data related to socioeconomic obtained through interview. Respondents interviewed was chosen purposively by 69 respondents. Secondary data was obtained from literature study and data from agencies that are related to research objectives, such as District Forestry office, village office, and Agricultural Extension Agency, Fisheries, Livestock and Forestry. Bamboo in Sukaharja Village has a potential of 765 bamboo stems per hectare with 53 % composition of young bamboo and 47 % old bamboo, dominated by 92 % Gigantlochoa apus. Bamboo in Sukaharja village can be sustainable because it is cultivated with agroforestry pattern. The pattern of bamboo agroforestry in Sukaharja village community is a) Bamboo + wood, b) Bamboo + HHBK, c) Bamboo + plantation crop, d) Bamboo + horticulture.Keywords: agroforestry, bamboo, Sukaharja village, sustainability

The purpose of this study was to determine the weed density and the dominant species of weeds in Malapari (Pongamia pinnata (L). Pierre) agroforestry. The study was conducted in Patutrejo Village, Grabag District, Purworejo Regency. The method used is single plot method in malapari agroforestry, as a comparison of observations of weeds on empty land that is not planted. Weed sample collection was carried out by the quadratic method measuring 1 m x 1 m as many as 3 plots placed in malapari agroforestry and empty land diagonally. Observations were repeated 3 times so that there were 18 observation plots. The results showed that weed density in malapari agroforestry (29.95) was lower than empty land (54.17). The dominant species of weeds in both malapari agroforestry and empty land is Eulalia amaura (Buese) with Important Value Index (IVI) of 36.40 % and 43.39 %. This species is a pioneer weed and fast growing, so monitoring and control are needed so that the weed population is not economically disserve.Keywords: agroforestry, density, dominant, malapari, weed

Teak (Tectona grandis) is one of popular and important carpentry wood in Indonesia. However teak production for carpentry material cannot balance the increasing need for domestic and export market. The increased production from small holder forest can be alternative way to supply national wood need. Therefore science and technology play role to support forest productivity eg superior seedling from vegetative propagation. The preparing of superior seed took several steps i.e. selection from mother tree, genetic material extraction, grafting activity using budding technique, hedge orchard establishment, and mass production used cutting rotted or tissue culture. From clonal test we can derive superior seed which adaptive with development location and has better productivity.

Climate change is difficult phenomenon to be understood by ordinary community. Whereas perception and knowledge of climate change will influence mitigation and adaptation, which can decrease risks of climate change impact. The research aims to find out community’s perception about climate change and adaptation efforts which have been done by communities of Sarawet Village at North Minahasa Regency. Perception and adaptation data were obtained through interview and focus group discussion. The result shows that 96.67 % of community has experienced the symptoms and impacts of climate change, which perceived as extreme season or the shift of rain and drought season. The most perceived climate change impacts are crop failure, less income from agriculture and drought. This perception indicates a lack of environmental and forestry information. The adaptation efforts that have been done by the community include change plant species that need lack water as well as fulfill needs of clean water from the central well and utilize springs from upstream. Based on SWOT analysis An appropriate strategy to encourage adaptation in Sarawet village is done through increasing the adaptive capacity of the community Keywords: perception, climate change, SWOT, adaptive capacity

The present study aims to determine the type of fodder available and the level of scarcity of Anoa’s fodder at the condition prior to captivity at the Forestry Research Institute of Manado. The method employed was a trial of 12 (twelve) types of fodder available around the captivity site given to 2 (two) female anoas. The data were analyzed and displayed in tables and graphs while the data of preferred fodder were analyzed using Neu’s index equation. The findings suggest that anoa put in captivity at the Forestry Research Institute of Manado did not encounter problems during the process of feeding adaptation. The average fodder needs required anoa at the captivity site of the Forestry Research Institute of Manado range from 10.2 to 11.7 kg/ day in which the fodder was given twice a day. Meanwhile, based on the availability and ease of supplying the fodder from around the captivity site, the following are the types of fodder from higher to lower preferences, namely: field grass, kangkung, shoes banana, string beans, beans and cucumbers, respectively. While fodder with the lowest level of scarcity is the type of fodder with a hard texture such as sweet potatoes, carrots or potatoes. Based on the results of a number of studies, it is recommended that variations in anoa’s fodder can be done every 4-5 times a day.
