Abstract

Rawa Danau Nature Reserve is an area of the old volcanic caldera located in Serang District, Banten Province about 100 km to the west of Jakarta. This area has been identified as a very important natural site on the island of Java. This is based on the fact that the main wetland ecosystem at Rawa Danau is the only remaining freshwater swamp forest ecosystem of peat swamp forests in Java Island. The objective of this study was to identify land cover classes and their changes in Rawa Danau Nature reserve area on 2006, 2011, and 2016, and also calculate degradation rate and reforestation during the time of observation. This study was conducted in April - June 2017. Data sources was generated from landat image  ETM+7 coverage year of 2006 and 2011, Image Landsat OLI 8 coverage year 2016 and other supporting digital maps. Supporting tools and instruments used were software, ArcGis 10.1, Erdas 9.1, GPS, Camera and Stationary. The result showed that land cover can be successfully classified both digitally or visually and  composed of secondary swamp forest, marsh bushes, fields, settlements, water body and swamp. Highest degradation during 2006-2016 occured on swamp forest that was converted into fields, while highest reforestation happened on fields that became swamp area.  Key words: Degradation, Image Landsat, Land Cover Changes, Land Cover

Abstract

Forests are one of the great natural resources of its role in various aspects of life both economic aspects, social, development and forest environment and its ecosystem as the basis of national development capital with the diversity of flora and fauna that can provide benefits for human life. One effort to support the balance of natural ecosystems and economic needs is the formation of community forests, aimed at increasing the income and welfare of the people. This can be seen from the existence of traditional folk forests in the effort of the community itself without the intervention of the government (pure self-help), either in the form of one species plant (pure forest), or with the pattern of agroforestry. The purpose of knowing about the potential and condition of community forest, and the amount of revenue contribution from the result of community forest management is compared with Minimum Regional Wage (UMR) Bogor Regency. Methods in this study using survey approach and analyzed qualitatively and quantitatively by using systematic sampling with random start with 20% sampling intensity. The result of research on the potential of community forest stands is 1.213,586 m3, derived from Sengon, Jabon, Acacia, Mahogany and Jati. The contribution of peasant forest income is on average 29,88% compared to UMR value of Bogor Regency.

Abstract

The issue of deforestation and forest degradation in Indonesia led to allegations of illegal logging practices against Indonesian timber products on the world market , so the stakeholder initiative to boost market confidence returning to the Indonesian wood products . Awareness of domestic industry actors against SVLK is still minimal.  Perception of actors who own S-LK is to gain the trust of customers, improve customer loyalty and ideals, have the legal recognition of the government's efforts, increase the value of its product, reducing the unofficial levies. While the perception of actors who do not have S-LK is their expensive cost factor, ordinances S-LK -making procedures are complicated, and does not know the procedure of making S–LK

Abstract

The existence of the community forest in Dangiang Village, Cilawu District, Garut Regency, has supported efforts to conserve forests that are a buffer for people's lives. Sustainable community forest management is influenced by community behavior, as well as factors that support and hinder community efforts in preserving community forests. This study aims to examine the behavior of the community in an effort to preserve community forests and their supporting and inhibiting factors. The research method used is descriptive method with a qualitative approach. The results of the study show that people's behavior is related to aspects of perception, participation, policy, cooperation, women's role, and cultural values / norms; Among them is maintaining the sustainability of community forests by planting, maintaining, and not carrying out activities that damage the forest. The community participates actively in the conservation activities. The supporting factors are the existence of local wisdom, active roles and community collaboration with stakeholders. The inhibiting factor is the economic function of the community forest which is still lacking, human resources are still low, and the accessibility of the area is inadequate. Utilization of community forest potential can increase community income through timber certification, identification of community forest products, increase collaboration between communities and stakeholders, and improve product yields in community forest areas.

Abstract

The objective of this research is to get Index of species diversity and habitat habitat characteristic in Garunggang Cave in July 2017.  The method used is the method of moving observation and time search. A total of 302 individuals consisting of 5 groups of taxa found in Cave of Garunggang (entrance 3). Species diversity in Cave of Garunggang in relatively medium condition (1 <H '<3) with value of diversity index (H') 1,9 based on variable of diversity type using Shannon-Wiener index. Based on its dominance there are 6 faunas that dominate, namely Hipposideros galeritus, Karstarma jacobsoni, Rhaphidophora Sp, Stygophrynus dammermani, Long leg spiders, and Small spiders. The fauna inside the Cave of Garunggang has a unique habitat such as on the floor, walls and roof of the cave. Cave Garunggang is a horizontal cave with a cave mouth circumference of about 3.7 meters and aisle length about 209 meters. This cave is karst cave (limestone). The diameter of the alley of the cave varies with underground rivers with stone and soil substrate and clear watery. The hallway inside the cave is branched off with several ornaments. In the rainy season the aisles become full of water and become a large underground river, evidenced by the presence of litter on the walls and roof of the cave that was carried by the water during the rainy season. The habitat characteristic of the exokarst Cave of Garunggang is known that the Cave of Garunggang has four zones within it, ie bright zone (cave mouth), transition zone, dark zone and total dark zone. At the bright zone (cave mouth) the temperature ranges from 31.8 ° C - 29.9 ° C, the humidity (Rh) ranges from 67.7% - 76.2% and the light intensity ranges from 475.3 - 848 Lux. At the temperature transition zone ranging from 30.4 ° C - 32.2 ° C, the humidity (Rh) ranges from 72.8% - 77.7%, the light intensity shows 0 Lux and the pH indicator shows the number 7 (normal water). In the dark zone the temperature ranges from 31.4 ° C - 30.4 ° C, the humidity (Rh) ranges from 77.1% - 79.1%, the light intensity shows 0 Lux and the pH indicator shows the number 6 (normal water). The final zone is a total dark zone with temperatures ranging from 30.1 ° C - 30.8 ° C, the humidity (Rh) ranges from 79.7% - 79.2%, the light intensity shows 0 Lux, and the pH indicator shows the number 6 (normal water).

Abstract

The copies JUN in the UNB Experimental Garden is the second rotation, this is an economic and ecological consideration. According to previous studies that sengon copies can be done in 3 rotations. JUN and sengon have similar physical characteristics of wood. The characteristics of the wood include the water content, density and density of wood. So that it is assumed, the growth of sengon stands also has similarities with the growth of JUN stands. In this research, it will be seen whether the JUN increment in the second rotation will produce results that are in line with expectations, and whether it will be feasible to continue in the third rotation. Riap in the second rotation will be a consideration for the next rotation. The prediction of increment in the next rotation can be calculated by knowing the increment in the second rotation. This study took a sample of 20% of the total population or as many as 1084 JUN copies stands. From this study it was concluded that the increment in the second rotation was 2.8 cm / year or decreased by 40%, so to obtain the lowest grade woodworking (AI) it took 7 years and 8 months. If it is continued in the third rotation it requires a cycle of 17 years 8 months to obtain an AI standard and requires a cycle of 26 years 8 months to obtain the AIII standard. From the results above, it is recommended that for JUN copies only until the second rotation because the predicted cycle is still below 10 years. The third rotation cannot be done because the growth of diameter increments is below 2 cm / year, so the cycle takes more than 10 years.
