Abstract

Two Falcataria moluccana (sengon) progeny trials, incorporating 100 different families from 12 provenances growing on two highly gall rust (Uromycladium falcatarium) prone sites were used to estimate genetic parameters and potentially identify rust-resistant material. The analysis was performed to assess provenance- and family-level survival, rust incidence, and growth at the two progeny trials. Height, diameter, survival, and rust incidence was measured at two progeny trials at 18 months-of-age located at Jember and Lumajang, East Java. Rust incidence at the two trial sites was severe, with only 39% overall survival (35% and 43% at Jember and Lumajang, respectively). The analysis revealed significant genetic variation at the provenance level for survival, rust incidence, and growth. No statistically meaningful narrow-sense heritability of these traits was indicated, though this is probably reflective of the inadequate within-family replication and effects associated with uneven stocking resulting from rust-induced mortality. The significant genotype-by-environment (provenance-by-site) interaction was also indicated, though the performance of some of the best- and worst-performing provenances was relatively stable, allowing recommendations of suitable provenances for further testing on rust-prone sites.

Abstract

Protected forests have drawn international attention.  This research aims to determine scenarios of land-use change in Protected Forest of Wosi Rendani (PFWR).  The study was conducted using land evaluation approach to land unit, determination and alternative land use change, based on the potential and the level of threat for PFWR.  The results showed that PFWR should remain as a protected forest although the total score of forest modeling was 130. This forest serves to protect soil, water, and danger from floods and landslides. This region has springs, caves, and waterfalls, which can be further developed into eco-tourism and environmental services. As a city forest, PFWR makes Manokwari's weather cooler, enhances the quality of air, reduces environmental pollution, and adds catchment areas. As a community forest, PFWR has forest plants, agricultural crops and fruits, in which people are only allowed to take flowers, fruits, and seeds they have planted. As a buffer zone, PFWR serves as a buffer to reduce population pressures on the forest area or village surrounding the area with high interaction by integrating conservation and economic interests of the surrounding community. As cultivation and settlement, PFWR has three settlements, namely Soribo, Kentestar, and Ipingoisi, 4 settlements outside PFWR namely Tanah Merah Indah, Ajoi, Buton, Mako Brimob, as well as plots of land owned by developers such as Bank Arfindo, Lumintu, Irman Jaya, and Suntari. The final scenario of the land use change in PFWR depends on the policy of local and central government.

Abstract

Development of protected forest is often considered to be a way to preserve biodiversity and ecosystem service.  To keep protected area, Indonesia government excludinged local people from protected forest by making a policy which prohibits grazing on protected forest. However, the success of protected forest management often depends on the perception of local people because the policy has affected livestock owners who have an interest in forest use. Exclusion of local people from protected forest leads loss of people income and unemployment. This study applied a socioeconomic approach to examine and analyze the livestock owner perception on forest grazing prohibition in Timor Island of Indonesia by conducting a household survey of 36 livestock owners. The study results showed that 30.6%, 50.0%, 19.4%, 0%, and 0% of livestock owners are totally disagree, disagree, neutral, agree, and totally agree, with grazing prohibition, respectively. In addition, people perception was significantly affected by the number of livestock owned by people. It means that livestock owners mostly reject the policy on grazing prohibition. Indeed policy which prohibits grazing on the protected forest is not effective to be implemented. Government and policy maker should review the policy and consider the refusal of livestock owner toward exclusion policy. The interest of local people should be considered in developing a policy on protected forest.

Abstract

Perhutani is mandated to manage approximately 2,445,006 ha forest in Java consisting of a production forest area of 1,806,449 ha and protected forest area of 638 558 ha (Perhutani 2014). Perhutani working area consists of several units of governance in the form of Forest Management Units (KPH). Currently, 57 KPH Perhutani is experiencing various problems that the function of conservation isnot going well.  KPH Pekalongan Barat is one of the KPH which is considered quite good. It can be seen from the compliance percentage each year that reaches about 90%. The approach used in this research is 1) financial feasibility analysis, 2) land use optimization analysis, 3) multi-criteria analysis. The first analysis is financial feasibility analysis. The research's output based on the financial aspect performs that the feasibility criteria of investment of the three land use options are feasible to execute. The broad composition for optimal land use is an area covering 11,047 ha of pine, a coffee area of 2,126 ha and vegetable area 668 ha with an income of IDR872,581,112,943. According to multi-criteria analysis, the existing vegetable area is in an unfeasible area, so it can be durable.

Abstract

The majority of wild orangutans are found outside of the protected areas, including in coal mining areas which generally overlapping with orangutan habitat. Thereby, mining ensured a direct impact on orangutans. Opportunities orangutans to survive in the mining area depends on various factors, one of them is the ability of orangutan to adapt to habitat change. We investigated habitat characteristics in the coal mining area consist of land cover types, species composition, and the structure of vegetation. Data were collected from April to September 2014 in the coal mining rehabilitation area (CMRA) of PT KPC in East Kutai. Mining caused the natural habitat fragmented into smaller patches in the form of CMRA and natural forests remaining. The forest stand in CMRA compiled by the small trees of the same species and age class. It caused the canopy is not always continue. Food trees and nest trees were limited in CMRA. Exotic species dominated in CMRA, namely: Senna siamea, Falcataria moluccana, and Senna surattensis. CMRA is not the good habitat for orangutan if seen from the aspect of either structure or vegetation composition. The quality of habitat can be improved by modifying the structure and vegetation composition, build the ecosystem corridors, increase public awareness, and involve various stakeholders at the landscape level.
