Abstract

Java Island is one of the tropical areas for bird migration, especially the Asian-Australian flyway of migratory birds. The SMETF is one of the protected forest areas that migratory birds can visit in Java. This research aims to identify migratory birds in SMETF. Transect and point count methods are used to observe migratory bird movements and their activities. In the research area, four migratory birds were identified: Ficedula zanthopygia, Agropsar sturninus, Pernis ptilorhynchus o., and Accipiter soloensis. The first and second species showed many activities for four months from October 2020 to January 2021, and this is an indication that both are using the research site as a wintering habitat. The activities of the Pernis ptilorhynchus o., Accipiter soloensis were dominated by flying “flock” over the forest. Only the Pernis ptilorhynchus was observed carrying out hunting activities, indicating that this bird uses the area as a stopover area. This research also identified illegal hunting techniques, such as ngaleugeut and mikat, as severe threats to migratory birds in the SMETF.

Abstract

The objective of this study was to evaluate the effects of torrefaction temperature on the physical and mechanical properties of betung bamboo (Dendrocalamus asper) pellets. Torrefaction was conducted in an electric furnace at 200°C, 240°C, and 280°C for 50 minutes. The physical properties evaluated included color change, density, moisture content, water resistance, and water adsorption. The mechanical properties were also investigated by compressive strength test. The result showed that torrefaction affected the color properties of betung bamboo pellets with ∆E values of more than 12 or totally changed. The density and moisture content of torrefaction bamboo betung pellets decreased with increasing torrefaction temperature. The results also showed that the hydrophobic properties of the bamboo betung pellets improved with the increased of torrefaction temperature. The highest compressive strength value was obtained by bamboo betung pellets torrefied at 200°C and the values decreased with the increase of temperature. In conclusion, there were differences in the physical and mechanical properties of bamboo betung pellets that were torrefied at different temperatures. Torrefaction with an electric furnace effectively improved the quality of betung bamboo pellets. Keywords:   Bamboo betung, pellets, temperature, torrefaction

Abstract

The development of avitourism in villages around the conservation area still needs optimal support to increase welfare and reduce illegal practices like bird hunting. Birds are wild animals that play an essential role in the ecosystem. One of the efforts that have been developed in the buffer village to improve the welfare community and the conservation of birds is avitourism. This study aimed to analyze birds that have the potential as objects and attractions in avitourism. The bird species recorded were 82 species from 39 families. The results of key informants’ perception analysis revealed that 55 bird species (67.07%) have the potential as objects and attractions of avitourism, showing the nocturnal birds, top 50 birds of Way Kambas National Park, and parrot species as the top classification (> 75%). The colorful, raptor, and protected criteria are second with the favorite classification (51-75%). Endemic and migrant criteria are in the third position with the impressive classification (25-50%), and the songbird criteria are the lowest with the interesting classification (< 25%). The existence of birds that have the potential as objects and attraction of avitourism in the villages around Way Kambas National Park indicates that areas can be used in locations for avitourism, including bird photography, to improve welfare.

Abstract

The sustainability of mangrove forests really depends on the involvement of communities in the areas surrounding the mangrove forests. If the mangrove environment is to be used in the long term, it must be managed and preserved. This research aims to determine strategies for sustainable mangrove management in Sumber Nadi Village, Ketapang District, South Lampung Regency. The method used in this research is a qualitative approach. Data was obtained through in-depth interviews involving key informants who were selected and determined using snowball sampling and analyzed using SWOT analysis of Strengths, Weaknesses, Opportunities and Threats, which includes Natural Resources and Human Resources. The results of this research show that the total value of the influence of internal strategies has a value difference of 0.32. Likewise, the external value has a difference of 0.11. Then, combining the two values of the difference between strengths and weaknesses and opportunities against threats, a coordinate point is obtained, namely the coordinate point (0.32; 0.11). The strategy that must be implemented in Sumber Nadi Village, Ketapang, is to support aggressive growth policies (growth-oriented strategy). Mangrove forest management strategies, as in the quadrant above, show a favorable situation. The relevant agencies, management and the community should support this management development strategy so that it can maintain the potential of existing mangroves
