Abstract

Land-use changes result from changes in the human population, their activities, and social and environmental activities, which occur in a complex and dynamic manner. The change of forested areas to non-forested areas, also known as deforestation, is a land-use change. Deforestation influences land cover by creating a specific distribution pattern (fragmentation). Almost the entire forest has been fragmented into smaller areas, but the pattern of each of these forest areas is uncertain. As a consequence, it would be more challenging to control potential deforestation. Using the spatial metrics of Clumpiness index, Contiguity index, and Patch density, deforestation in one of the forest areas, namely the Ko'mara forest area, was carried out. This research was analyzed using GIS and Fragstat software in raster data format. The analysis results show that the spatial pattern of deforestation in this area has a clumped distribution, with a high level of patch contiguity and a low to medium level of fragmentation. This pattern represents the form of deforestation in the Ko'mara forest area in 2005-2010 and 2010-2015 was classified as Low Deforestation with a deforestation rate of <1%, but was classified as Moderate Deforestation in 2015-2019 because the value obtained was 1.1%.

Abstract

Nickel (Ni) and associated minerals (Cr and Mn) are naturally occurring substances in ultramafic laterites soil. It may be found in our vegetables and grains when agriculture is grown in ultramafic laterites. This study aimed to assess the contamination of Ni in edible crops affected by soil volume in mono- and mixed cropping on limonitic laterite soil. The investigation was conducted on Peanut (Arachis hypogaea L.) and Choy Sum (Brassica rapa var. parachinensis) in three different pots sizes-representing soil volume to support root growth, which was filled with 0.5 kg (small), 1.0 kg (medium), and 1.5 kg (big) of limonitic laterite soil, respectively. The limonitic soil has a 7.884 mg kg-1 Ni concentration. The experiment shows that Ni concentration in peanut and Choy Sum shoots of mono-cropping in small, medium, and big pots achieve 20, 90, 120 mg kg-1 and 51, 67, and 95 mg kg-1, respectively. Meanwhile, in mixed cropping, Ni concentration in small, medium, and big pots of peanut and Choy Sum shoots are lower only by 33, 50, and 51 mg kg-1 and 15, 52, and 63 mg kg-1, respectively. Contamination of Ni in Peanut and Choy Sum shoots increases with the increasing soil volume, and mixed cropping is a potential strategy to reduce the acquisition of Ni.

Abstract

Forest fires are not solely determined by the quantity and quality of plant debris as fuel, but also influenced by some extrinsic factors. This study aims to examine the effect of some factors (slopes, tree density, and tree basal area) on the intensity of forest fires. The study was conducted in a 1 ha (100m x 100m) plot in the Pinus merkusii plantation 10 months after the fire. The plot was divided into 10 m x 10 m subplots, therefore there were 100 subplots. Each tree over 5 cm in diameter found in the plot was numbered consecutively, recorded its species name, measured its diameter, and determined whether it was alive or dead. The slope level in each subplot was measured. Multiple regression analysis was used to detect the influence of slope level, tree density, and basal area on the number of dead trees in each subplot. Results show that slopes, tree density, and basal area influenced proportionally the intensity of forest fires (R2 = 0,507; p<0.05). However, when the partial analysis was applied to detect the influence of each class factor, not all of the classes were found significant. These results reveal that there are several other factors not measured in this study that also influence fire intensity, which we suspect are tapping holes and tree diameter.

Abstract

The Editorial Board has issued this editorial note in the form of a review to inform contributors about changes to the scope of the Journal of Wallacea Forestry Research (JPK Wallacea) following the transfer of management from Balai Penerapan Instrumen Lingkungan Hidup dan Kehutanan Makassar to Hasanuddin University's Forest Conservation Study Program in 2023. JPK Wallacea is no longer limiting its scope to forestry and is expanded to cover biodiversity in general by incorporating the term Wallaceae, which is a biogeographical area located between the continents of Asia and Australia. This area is well known for its unique biodiversity both on land and in water. The Wallacea region's biodiversity is famed for its distinctiveness yet, it is on the verge of extinction. Thus, the Editorial Board chose to focus on the scope of JPK Wallacea on scientific, technological, and policy conservation features. This scientific publication is expected to make a substantial contribution to the biodiversity conservation effort in the Wallacea region and its surroundings.

Abstract

Research on richness and bird species diversity are important for conservation efforts in National Park. Currently, the Aketajawe Lolobata National Park (ALNP) is a habitat patch among industrial areas on Halmahera Island, so that it is important to carry out periodic bird inventories in the national park. Therefore, the need to study the current bird diversity and the status of bird species as a basis for future monitoring and implementation of appropriate conservation measures are important. Bird diversity research needs to be carried out because. Observation plots are placed at primary and secondary forest in Akejawi resort. The research was conducted on January to February 2022. Total observation point is 20 plots. The method was used by point count. The distance between the observation plot is 200 m and the radius of observation is 50 m. The observation were made in the morning (06.00-09.00 am). Repetition of observation on each habitat was carried out 10 times. Data were analyzed by using Shannon-Wiener Index Diversity. Based on findings, There were 345 individuals of 39 species from 19 families inhabited Akejawi Resort. Secondary forest had the highest diversity index when compared to primary forest. This study revealed  that there were 9 birds originated from North Maluku and there were 15 species categorized as protected species. The latest data can provide opportunities for further research to reveal patterns of bird distribution and various protection measures due to the loss of forest areas around national parks.

Abstract

Humans and nature cannot be separated because both have a close relationship as an ecosystem. The purpose of this study was to determine: 1) the level of social and ecological resilience; 2) Scenarios on ecological and social factors for the sustainability of protected forests. The research method uses survey methods and data analysis uses qualitative-verification analysis based on the results of the calculation of the resilience index and the phase of the socio-ecological system. The results showed that the level of social and economic resilience was partially or simultaneously at the level of resilience with their respective indexes: social: 0.6944); ecology: 0.8148 and socio-ecology 0.7460. The exploitation phase (growth) leads to the conservation phase. The results of the scene show that both of them are at a high level of resilience with a resilience index of 0.8889 (high resilience) and a reorganization phase. If this phase can be maintained with various management interventions according to its function, it will minimize the level of disturbance to the Mount Sirimau Protection Forest Group.

Abstract

Maleo (Macrocephalon maleo) is one of the endangered bird species in Indonesia. This avifauna species is an endemic bird to Sulawesi Island. It is distributed from the south to the north of Sulawesi, including Gorontalo. Currently, information on suitable habitat models for M. maleo is very limited, while this information is required to support the conservation of M. maleo. This study aimed to model the potential habitat for M. maleo using species distribution modeling (SDM) with vegetation cover variables as predictors. The model was built based on the M. maleo occurrence points. The suitable habitat was then evaluated using area under the curve analysis and the receiver operating characteristic curve (AUCROC). Based on the model, the AUC is valued at 0.729, which is considered reasonable and indicates that the model can be used to depict the potential habitats for the species. In this study, most of the west and east parts of Gorontalo were considered not suitable for Maleo. While the coastal areas of Gorontalo were considered very suitable. This was confirmed for both the north and south coastal areas of Gorontalo. Then it is strongly recommended to conserve and protect most of those coasts to ensure the Maleo conservation.
