Abstract

Terrain analysis and elevation profiling are widely utilized in geographical studies where spatial information system is one of the foremost tools in assessing characteristic patterns of hiking trails and plain areas suitable for a campsite. The main objective of this study is to classify the landforms of Batu Gangan Forest Reserve by conducting a morphometric analysis of the Digital Elevation Model (DEM) with 10m resolution. The classification process is based on calculating the Topographic Position Index (TPI). Using TPI, the landscape was classified into slope position and landform categories. The delivered TPI landform classes are spatially correlated with the elevation, slope, LS factor, and topographic wetness of the mountain. Site observation was carried out to identify water sources, viewpoints, and their significance as suitable campsites and potential trail. An alternative trail was proposed to reduce the visitor impacts towards the main trails. The result suggested that the plains landform only covered 3.26% or 2.03km2 of the study area, where two potential campsites were identified. The method presented and research findings derived from the study are beneficial to support sustainable recreation resource planning, especially in a complex mountainous area. The study's findings and data will lead to proper forest use for recreational reasons consistent with conservation efforts.

Abstract

Forest fragmentation is a threat to ecosystems in Indonesia caused by forest conversion to plantations. This study aims to analyze the use of land cover in the period 2013-2022. The research was conducted from November 2022 to January 2023 in the Gayo highland area by taking case studies in 2 regions including the Central Aceh District and Bener Meriah District. The research was carried out in several stages, namely: image pre-processing, image visual interpretation, making image classification class identifiers, and ground checking. The pre-processing stage is the preparation of tools and materials. Landsat 8 OLI imagery for the study area downloaded from the United States Geological Survey (USGS) website. The results of the research show that in the last 10 years there has been a decrease in the area of land cover in the exploration area of primary forest and secondary forest. Meanwhile, in the cultivation of dry fields, settlements, plantations and vacant land, land use has increased. Changes in the use of land cover are influenced by community activities in Central Aceh and Bener Meriah Regencies.

Abstract

Evaluating land suitability for Aleurites moluccana in community agroforestry land within Langkat District, North Sumatra, is crucial for promoting sustainable development, enhancing livelihoods, and preserving ecosystems while honoring local traditions and cultures. The primary objective of this research was to evaluate and map the land suitability for A. moluccana within Langkat District, located in North Sumatra, Indonesia. To gather the necessary data, this study employed a survey method, involving the collection of soil samples from ten distinct land units within the field. The assessment of land suitability was carried out using the matching method. Geographic Information System (GIS) technology was utilized to create maps illustrating the distribution of land suitability, while a Global Positioning System (GPS) was employed to accurately record the coordinates of the collected soil samples. The findings revealed that within Gunung Ambat, Simpang Kuta Buluh, Rumah Galuh, and Telagah Village, the actual land suitability classes for A. moluccana were classified as moderately suitable (S2) and marginally suitable (S3). The prevailing limiting factors in this region were temperature (tc) and the characteristics of the root zone medium (rc). Consequently, this influenced the potential land suitability classes for A. moluccana, resulting in classifications ranging from highly suitable (S1) to moderately suitable (S2) and marginally suitable (S3). By implementing land suitability evaluation for A. moluccana in community agroforestry land, promoting sustainable land use, enhancing livelihoods, and conserving natural resources.

Abstract

Corruption and forest disturbances represent substantial barriers to sustainabledevelopment in Malaysia's forestry sector. Working within this sector faces avariety of threats. This study explores key corruption risks within the forestrysector, analysing the motives and opportunities that drive forest offences inPeninsular Malaysia. Respondents from relevant agencies were primarilysurveyed using questionnaires. Data analysis using SPSS revealed the corruptionrisks encountered within the forestry sector. Respondents identified fieldwork andreporting as potential areas susceptible to corruption, with their perceptionsanalyzed through central tendency and dispersion measures. Additionally,correlation analysis was conducted to determine the strength and direction of therelationship between motive and opportunity regarding forest offences, and toassess whether the correlation was statistically significant. The findingsdemonstrated a robust positive correlation (r = 0.66) between motive andopportunity, indicating a significant relationship. This suggests that motives forforest offences correspond to opportunities for such offences. This studyhighlights the need for targeted collaboration between the Forestry Departmentand relevant authorities to develop specialized training programs. These programsare crucial for effectively investigating and prosecuting forest violations,ultimately reducing corruption risks

Abstract

Mangrove ecosystems are important in ecological, economic, and social aspects,especially for coastal communities. However, damage to mangrove ecosystemsdue to land-use changes for purposes such as settlements and fish ponds canthreaten their sustainability. This study aims to analyze the potential of themangrove ecosystem, apply the kao-kao model in silvofishery pond management,and analyze the potential of mangroves in increasing the income of the communityin Pematang Kuala Village, Teluk Mengkudu Sub-district, Serdang BedagaiDistrict, North Sumatra Province. The methods used include field surveys forvegetation analysis and interviews with Kelompok Usaha Bersama (KUB)Nelayan Sepakat members. Vegetation analysis was conducted in three zones:utilization zone I, II, and the protection zone. Each zone consisted of 5 plots,totaling 15 plots. Interviews were conducted with 27 respondents. The studyresults showed that the mangrove ecosystem in Pematang Kuala Village isdominated by Avicennia marina and Rhizophora mangle, with an important valueindex of 300 in both utilization and protection zones. In the protection zone, theShannon-Wiener diversity index was 0.95, indicating a low level of diversity.Based on the kao-kao system model, it was observed that the productivity of fishponds and fishermen's catch increased. Community income has significantlyincreased over the last five years, with an average net income of IDR 19,550,000every six months. The presence of mangroves also provides indirect benefits as acoastal protector from abrasion, with an estimated economic value of IDR247,950,000 per year.

Abstract

This study investigates why applicants who have passed the initial admissions stage do not proceed to final enrolment in an Indonesian private higher education context. While student recruitment is often measured by the number of applications received, institutional sustainability depends on the ability to convert applicants into enrolled students. This study employed a descriptive survey design supported by thematic analysis of open-ended responses. Data were collected from 179 applicants who had participated in the admissions process but did not complete final re-registration. The data were analyzed using frequencies, percentages, and thematic categorization. The findings show that conversion failure is influenced by several factors, including waiting for public university admission results, financial constraints, postponement of study plans, family considerations, uncertainty about the institution or study programmed, preference for other institutions, and campus accessibility. A key finding reveals that 58.1% of respondents would reconsider enrolment if scholarships, tuition discounts, or other financial assistance were available. These findings highlight the need for a conversion management strategy through targeted financial aid, transparent cost communication, family engagement, and proactive applicant follow-up.
