Abstract

Bucking is a forest harvesting stage that determines the quality of round wood. The bucking in private forests uses a chainsaw. Efficient bucking process is a prerequisite for sustainable forest harvesting. The study aimed to analyze the working time and productivity of bucking using a chainsaw in private forests. The study was conducted in private forests planted with an agroforestry pattern in the Probolinggo district, East Java. Working time measurements are carried out based on analysis of video images recorded during data collection in the field. The number of bucking work cycles observed was 31 cycles. Regression analysis was used to analyze the relationship between the logs' diameter and length and the bucking's productivity. The average working time for bucking was 7.09 minutes per cycle, consisting of 77.84% working time and 22.16% non-working time. The average productivity of bucking was 2.51 m3/hour. The study provided important empirical results regarding bucking's working time and productivity in private forests where the type of felled tree was sengon. Hopefully, the study results will be useful in planning and developing bucking techniques in private forests in Indonesia.

Abstract

Indonesia is one of the countries with the largest blue carbon ecosystems in the world. This is due to its long coastline and vast marine areas. Indonesia has the largest mangrove forests in the world, covering approximately 3.3 million hectares, spread across the coasts of Sumatra, Kalimantan, Sulawesi, Papua, and Java. The method used in this research is bibliometric analysis, a quantitative approach to analyzing scientific literature to identify publication patterns, research trends, scientific impact, author collaborations, and relationships between scholarly works. Based on the results, it was found that among the 10 most productive authors, Murdiyanto is the most productive, with 13 publications. In terms of institutional affiliation, authors come from institutions such as Bogor Agricultural University, the National Research Agency, and the Center for International Forestry Research. Bibliometric mapping using Vos-viewer, through co-occurrence analysis for network, overlay, and density visualization, shows that topics related to blue carbon and mangroves, such as organic carbon, carbon storage, carbon emissions, and mangroves, were trending between 2021 and 2024. However, these topics as a whole have not been widely researched.

Abstract

Pulang Pisau Regency faces significant pressure from human activities that threaten the sustainability of its forests. The phenomenon of deforestation and land conversion is important for understanding the dynamics of land cover change. Social forestry programs potentially contribute to reducing the rate of change in forest cover. This study aims to analyze land cover change on the Indicative Social Forestry Map (PIAPS) in Pulang Pisau Regency. The research method used Landsat-7 images recorded in 2000 and Landsat-8 images recorded in 2020, PIAPS data, and land cover classification using the Random Forest model with Quantum GIS and Google Earth Engine (GEE) software. The research shows that there has been a significant land cover change over a decade in the Indicative Map of Social Forestry in Pulang Pisau District. Forest cover has decreased from 41,149 ha in 2000 to 23,836 ha in 2020. The average accuracy of land cover showed an OA value of 95% and KA of 92%, which is categorized as good. This study thus highlights the importance of maintaining forest cover to address future land change dynamics through social forestry scheme programs

Abstract

The sustainability of forest functions is closely related to the perspective of the communities living around it. This study aims to analyze community perspectives on forest conditions in KTH Talang Ponijan and Sidodadi I. Data was collected using a qualitative approach through in-depth interviews, participant observation, and documentation studies. The collected data were analyzed descriptively and qualitatively. The results of the research show that there are still differences between the community's views and their behavior towards community forest management (HKm). Most people in KTH Talang Ponijan and Sidodadi I utilize HKm land to improve their welfare. However, conditions in the field reveal that illegal practices such as logging, poaching, opening up new land for cultivation, and unsustainable land management threaten the balance of nature and worsen forest conditions. The government is expected to provide environmental education programs and facilitate training or guidance to strengthen the community's capacity to manage and utilize forests wisely.

Abstract

The pitih wood plant (Melaleuca leucadendra) is a type of plant that belongs to the guava tribe (Myrtaceae) which can produce one of the essential oil products in Indonesia. Eucalyptus plants can be cultivated by generative (seed) and vegetative propagation methods (shoot cuttings with rejuvination techniques, branch cuttings, shoot cuttings, root cuttings, grafts).  However, related to the root structure of the rhizome and the value of the biomass content of this plant, it has not been widely published. This is the impetus to conduct research related to the root structure of the rhizome and the biomass content and stored carbon content of the eucalyptus plant section by direct measurement methods in the field and analysis in the laboratory. From the plot of eucalyptus plants, it can be seen that the selected sample has sturdy rhizome roots with similar plant height characteristics, both for the growth rate of the mother plant and the saplings of the mother plant which generally have an even height and are not too.

Abstract

Food is one of the crucial factors for the survival of birds. The interaction between habitats and birds, as well as the role of birds as environmental bioindicators, can be understood through feeding guilds by examining their responses to disturbances. This study aims to analyze the feeding guilds of bird communities on Pasoso Island. The data collection method used was the strip transect method. Data were analyzed using descriptive analysis based on bird species composition according to their guilds. The results of this study show that 33 bird species were found on Pasoso Island, classified into 10 types of feeding guilds. Based on the number of species, the insect-eating guild had the highest number (9 species) compared to other guild categories. The coastal invertebrate-eating guild and raptor guild had the fewest species, with only one species recorded in each. Regarding the number of individuals, the insect-eating guild dominated with 42 individuals, followed by the fruit-eating guild with 29 individuals. On average, the fewest individuals were found in the coastal invertebrate-eating and raptor guilds, with only one individual in each.

Abstract

Home gardens have significant potential to improve communities' economic, ecological, and social welfare. This study examines the socio-economic conditions and home garden utilization practices of the community in the Wan Abdul Rachman Grand Forest Park (Tahura WAR) conservation area, located in Sungai Langka Village, Pesawaran Regency, Lampung Province. Data was collected through direct interviews using structured questionnaires, with respondents selected via the Simple Random Sampling method. Descriptive analytical methods were employed for data analysis. The results reveal that 83.33% of farmers in Sungai Langka are adults aged 27–40 years, all male. The farmers belong to three ethnic groups: Javanese, Lampungese, and Sundanese, with Javanese being the majority. Most farmers (63.33%) have a secondary education level, and 83.33% engage in secondary occupations. According to the Indonesian Statistical Agency/BPS (2021) income classification, 74.5% of the population falls into the middle-income category. The average homegarden size is approximately 100 m². The majority of homegardens (90.33%) are utilized as yard gardens, followed by livestock shelters (66.33%), ornamental gardens (40.66%), and fishponds (20.55%). These findings highlight the pivotal role of homegardens in supporting the livelihoods of communities near conservation areas. This study underscores the importance of optimizing homegarden management to enhance community welfare while mitigating pressures on conservation forests.

Abstract

Ranau Lake is one of Indonesia's 30 national priority lakes facing pressures from climate change and human activities, negatively impacting its water quality and ecosystem. This study aims to analyze land cover changes in the catchment area, measure the changes in the lake's surface area, and examine the relationship between land cover changes and Ranau Lake's surface area from 2016–2022. The data includes Sentinel-1A IW GRDH imagery, ESRI land cover maps, and Google Earth images. The analysis employed Support Vector Machine (SVM) classification, spatial analysis, and linear regression. The results reveal that water bodies, vegetation, and built-up land categories experienced an increase of 36.78 hectares, 33.96 hectares, and 9.1 hectares, respectively, while bare land decreased by 80.03 hectares. Ranau Lake's surface area increased by 28.3 hectares, showing a significant relationship between land cover changes in water bodies (R² = 99.88%), bare land (R² = 94.92%), vegetation (R² = 66.06%), and built-up land (R² = 56.85%) and the lake's surface area. These findings highlight the critical role of land cover changes in influencing the dynamics of lake surface area, an essential indicator of ecosystem health. This study emphasizes the importance of sustainable land cover management in supporting Ranau Lake's conservation. Continuous use of SAR-based remote sensing technology is recommended for land cover monitoring, enabling data-driven decision-making in water resource management.

Abstract

Peatlands are vulnerable to fire, causing ecological damage that threatens biodiversity, one of which is amphibians. The nature of amphibians which are sensitive to environmental changes can be used as a bioindicator of the quality of a disturbed environment, including in buffer villages around conservation areas. This research aims to analyze the diversity of amphibians and their relationship with temperature and air humidity. The method used is Visual Encounter Survey (VES) in two types of habitats, namely oil palm plantations and swamps. Data analysis used the Shannon-Wiener species diversity index, the Pielou species evenness index, and the Pearson correlation test. The research results found 6 species of amphibians, namely Hylarana erythraea, Hylarana nicobariensis, Fejervarya limnocharis, Fejervarya cancrivora, Duttaphrynus melanustictus, and Hylarana baramica. The diversity index (H') in oil palm plantations and swamps is H'=1.46 and H'=1.10 in the medium category. This shows that ecologically, the conditions of the habitat types of oil palm plantations and swamps in the buffer villages around the Orang Kayo Hitam Forest Park after land burning can support amphibian life. Key words: Amphibians, conservation area, diversity, tropical peatland.
