Abstract

A major challenge for the country is ensuring sufficient food production to meet the demands of its growing population. To address this issue, it is essential to enhance local root crop production as future food security. This study aims to assess the available and suitable land for Banggai Yam cultivation. The Multicriteria Evaluation Method was utilized to evaluate land suitability, while land availability was determined by integrating land use and land cover actual, forest area, and spatial pattern maps. The analysis revealed that 99,197 hectares are available for crop development. Expert assessment using the Analytic Hierarchy Process identified key land parameters such as cation exchange capacity, Base saturation, texture, and climatic factors like rainfall vital for determining land suitability, totaling 232,250.7 hectares. The combined maps indicated 95,301.6 hectares as potential development areas, with highly suitable land at 2.8%, moderately suitable land at 29%, and marginally suitable land at 8.3%. Conversely, land classified as unsuitable for cultivation constitutes 59.9%. These findings provide valuable insights for government officials, farmers, and researchers to optimize land use for these crops as a means to meet national food requirements.

Abstract

The agricultural sector significantly contributes to economic growth at local and national levels, reflecting broader social changes to improve materially and spiritual better living conditions. This research aims to assess income levels and identify constraints in the development of Banggai yam as a local food source. The research was conducted in the Banggai Islands Regency using quantitative descriptive analysis and the Interpretative Structural Modelling (ISM) approach. Respondents were selected using a stratified purposive sampling technique, resulting in 76 interviews, which included 68 farmers, 2 financial institutions, 4 government representatives, and 2 academics from the region. Findings show that Banggai yam farming generates significant financial returns, increasing farmers' income over the course of one growing season, thus categorizing it as a viable farming practice in the Banggai Islands Regency. Six key strategies for developing Banggai yam as a local food source were identified: government support (E7), farmer training and mentoring (E8), uncoordinated marketing (E1), annual Banggai yam cultivation (E5), shifting cultivation practices (E6), and unregulated land use (E14). Effectively addressing these constraints and prioritizing strategies will ultimately drive the goal of increasing incomes and guide the sustainable development of Banggai yam in the Banggai Islands Regency

Abstract

The Flores hawk-eagle (Nisaetus floris) is an endangered raptor endemic to the Lesser Sunda region and remains understudied, hindering effective conservation planning. This study investigates the species’ home range, habitat use, and threats at two active nesting sites in Ende District, Flores Island. Home range estimates varied between 8.439 km² (using minimum convex polygon/MCP) and 23.38 km² (using hypothetical-circular home range/HCHR) in Wolojita and from 6.385 km² (MCP) to 23.38 km² (HCHR) in Mbuli. Intensive use areas were relatively small, measuring 0.449 km² in Wolojita and 0.494 km² in Mbuli. Habitat use analysis revealed that in Wolojita, the eagles favored secondary forests, settlements, and shrublands, while in Mbuli, they primarily utilized grasslands and secondary forests, actively avoiding agricultural lands, rice fields, and areas near sulfuric rivers. Secondary forests appear to provide essential resources such as nesting trees and prey availability. However, competition with other raptor species, coupled with anthropogenic threats such as habitat degradation, land-use change, and persecution driven by livestock predation, poses significant risks to the species’ survival. Conservation should focus on preserving secondary forests, promoting sustainable land-use practices, and mitigating human-wildlife conflict to ensure the long-term viability of the population.

Abstract

Land use and land cover (LULC) changes can influence policies in a region due to economic and social conditions caused by population growth. The objective of this study is to analyze and map LULC changes in 2002, 2012, and 2022 using the Random Forest approach on Google Earth Engine, and to predict land use in 2042 using Markov-CA, thereby supporting the provision of accurate and sustainable policy data related to LULC in Banggai Islands Regency. This method can provide accurate information about the spatial distribution of rational LULC, balancing development demands with sustainable environmental protection. The study's results indicate that LULC has undergone significant changes from 2002 to 2022. There has been an increase in plantation land, open land, and settlements originating from forest and scrubland. Predictions of LULC changes in 2042 show an increase in plantations, settlements, and open land, while other land uses are declining. Effective land use policies require spatial planning that considers the potential andlimitations of land, as well as the space needs for residential, agricultural, and forest areas. This approach will facilitate the application of land conservation principles in sustainable, balanced agricultural and non-agricultural development in Banggai Islands Regency.

Islamic boarding schools are an essential element and can form agents of change in people's behavior and attitudes towards the environment. This study aims to examine the level of students' knowledge, the attitudes and the behavior of students at Darut Tafsir Islamic Boarding School towards the environment. and to analyze the relationship among the three. This research was conducted at Darut Tafsir Islamic Boarding School, Ciampea, Bogor from February to April 2022. This study used multiple regression analysis to analyze the relationship between students' knowledge and conservation attitudes and students' environmental behavior. Descriptive analysis is used to see the level of environmental knowledge, conservation attitudes and environmental behavior of students. The results of the study showed that the average level of environmental knowledge among students was 73.5%, and the attitude towards conservation was 60.5%. Students' environmental behavior averaged 65.3%. The coefficient of determination R2 in the regression is 0.639, meaning that the contribution of environmental knowledge and conservation attitudes to environmental behavior is only 63.9%. To improve students' environmental behavior, it is necessary to improve environmental education in the boarding schools.

Abstract

Meningkatnya jumlah wisatawan ke kawasan Geopark Ciletuh-Palabuhanratu (GCP) pasca diresmikan sebagai bagian dari UNESCO Global Geopark berpotensi menimbulkan kerusakan lingkungan, situs geologi, dan kondisi keanekaragaman hayati di kawasan tersebut. Oleh karena itu, perlu dilakukan antisipasi dengan membatasi pengunjung sesuai daya dukung melalui konservasi kawasan. Penelitian ini bertujuan untuk menganalisis daya dukung Curug Cimarinjung dan Puncak Darma dengan metode Douglass dan kemauan membayar (WTP) biaya konservasi dengan menggunakan Contingent Valuation Method (CVM). Responden penelitian sebanyak 150 wisatawan dan beberapa pengelola wisata. Kawasan Curug Cimarinjung mampu menampung sebanyak 184 orang/hari, dan kawasan Puncak Darma sebanyak 118 orang/hari. Pada tingkat daya dukung tersebut, wisatawan dapat melakukan aktivitas wisata dengan santai dan nyaman. Hasil penelitian menunjukkan jumlah wisatawan baik di Curug Cimarinjung maupun di Puncak Darma sudah melebihi daya dukung kawasan. Wisatawan yang bersedia membayar biaya konservasi sebanyak 78% dari total responden dengan mekanisme pembayaran satu kali melalui tiket masuk. Alasan responden tidak bersedia membayar biaya konservasi adalah karena responden menganggap ini tanggung jawab pemerintah 39,39%, takut uangnya disalahgunakan 27,27%, tanggung jawab pengelola wisata 24,24% dan pihak yang tidak peduli 9,09%. Nilai WTP dana konservasi sebesar Rp. 7.867 untuk Curug Cimarinjung dan Rp. 5.000 untuk Puncak Darma.

Abstract

The Javan Hawk-Eagle (Nisaetus bartelsi), an endemic species of Java, has been occasionally observed in Bali, prompting the need for scientific verification due to its critical conservation status. This study aimed to confirm the presence of the Javan Hawk-Eagle in Bali and map its potential distribution based on habitat suitability using an integrated spatial-ecological approach. A probability distribution model was developed using logistic regression with NDVI (Normalized Difference Vegetation Index), slope, and elevation as predictor variables. The resulting probability map was subsequently delineated using land cover, land use data, and information obtained directly from key informant interviews to produce a refined predicted suitable habitat patches map for the Javan hawk-eagle. To confirm its reliability, we conducted patch occupancy surveys to confirm the Javan Hawk-Eagles existence in patches that have historical occurrence of Javan Hawk-Eagle. Logistic regression modeling identified the Javan Hawk-Eagle's potential distribution area of 1,069.4 km². Using this model and information from key informants, forest function maps, and land cover maps, 14 predicted habitat patches were delineated. Subsequent patch occupancy surveys confirmed three of these patches as actual habitats for the Javan Hawk-Eagle on Bali, namely West Bali Protected Forest, Batukaru and Batukahu Area, and Buyan-Tamblingan Lake Tourism Forest. These findings provide the first empirically validated confirmation of the Javan Hawk-Eagle’s presence in Bali, supported by direct photographed observations verified by experts, and delineate key habitat patches for future conservation planning.

Abstract

Increased habitat pressure is indicated by high levels of human-tiger conflict (HTC). For Sumatran tigers to survive, structural corridor management is essential to managing the tiger metapopulation. Since 2016, Agam Regency has seen a sharp rise in HTC. This exploratory study aimed to understand variations in the corridor's forest cover and to evaluate the relationship between landscape metric indicators and fluctuations in HTC density. Agam's corridor is separated into 31 grids (3x3km). HTC information was gathered from earlier studies and web searches for incidents from 2000 to 2024. Tropical Forest Monitoring's landcover dataset was obtained through the use of a Google Earth Engine script. The LecoS plug-in is used to calculate landscape metric indices. For non-normally distributed data, the Spearman correlation statistic (95% CI) is employed. Before the HTC series in 2016, there was a twofold increase in deforestation, from 0.56% to 1.1% between 2010 and 2015. Nine landscape metrics, including forest area, forest proportion, NP, PD, GPA, LPI, PCI, and splitting index, exhibited a significant correlation with HTC density (p-value < 0.05). Around the corridor, high HTC density was associated with PD >10 patches km-2, LPI <44%, forest fraction <50.76%, and more disaggregated patches (PCI<9.79%). Since it may not be feasible to reduce HTC to zero incidents in the vicinity of human-dominated tiger habitats, expectations should be moderated, as lower HTC density occurs in wider landscape metric ranges. Improving PCI by aggregating patches and reducing NP while maintaining the remaining forest can potentially reduce HTC incidents and increase corridor function in tiger metapopulation management. The challenges are enormous, as  94% the corridor is in a non-protected area.

Abstract

Gunung Halimun Salak National Park (NP) is recognized as an important habitat for rare or key species of Java Island such as the Javan Hawk-eagle, Javan leopard, and Javan gibbon. Although these species exhibit different movement patterns (aerial, arboreal, and terrestrial), their spatial overlap within the landscape suggests potential ecological interactions, particularly within the trophic structure which is rarely integrated before. This study aims to identify, describe, and provide recommendations for the management of key species shared habitats based on spatial approach. Spatial analysis was used to examine the distribution of shared habitats and their biophysical characteristics, including land cover, elevation, and slope. A literature and policy review was conducted to align the findings with existing Conservation Strategies and Action Plans, based on applicable regulations and NP zonation. The analysis reveals that habitat distribution within the NP is categorized into 28.78% two key species and 55.84% three key species shared habitat. Biophysically, key species shared habitat is primarily found in forested areas between 500–1,500 meters above sea level (masl), and mostly located on steep slope around 25–45%. In terms of Gunung Halimun Salak NP zonation, two key species and three key species habitats are mainly located within the core, forest, and use zones of the Gunung Halimun Salak NP. The recommendations are developed aligned with the Conservation Strategy and Action Plan, regulations, and NP zonation for the comprehensive and integrated habitat management strategies of the key species shared habitat.

Abstract

The current understanding of food security significantly impacts agricultural policy, especially regarding the availability of food to meet local and national needs. The Banggai yam is a local carbohydrate crop in Banggai Islands Regency that plays a vital role in food diversification and security. Thanks to its high carbohydrate content, this tuber has great potential as a food reserve and an alternative to rice to support food sovereignty in Banggai Islands Regency. To cope with the increasing demand, a comprehensive development plan is needed. This research aims to develop a model of Banggai yam production and needs as a fulfilment of food availability in the Banggai Islands Regency. This research uses a dynamic system approach. The dynamic system can describe the relationship between various variables in its development. The results of the study indicate that the current level of Banggai yam production is insufficient to meet overall demand. Currently, there is a production deficit of 1,703.54 tons for Banggai yam in 2018, which is projected to decrease to 1,514.9 tons by 2042. Simulation results indicate that with a 1.2 percent increase in the planting index, a 1 percent expansion of new land, and a 4 percent increase in exports in Scenario 1, which is overall moderate, a surplus of 3.3 tons will be achieved, with production reaching 11,846.8 tons and demand at 11,843.5 tons. This scenario will meet the total demand for Banggai yam until 2042. Successful implementation depends on the involvement of various stakeholders, including the government, farmers, and businesses involved in Banggai sweet potato production, making this commodity a flagship food product in Banggai Islands Regency.
