Abstract

Biomass estimation model can be derived from satellite imageries and field measurements. This study built the estimation model using Landsat 8 image. This study was conducted in Hutan Nagari Padang Limau Sundai Sangir Jujuan, South Solok District, West Sumatera Province. This study aimed to build biomass estimation model and to study distribution of biomass over forest area using digital number of bands 4, 5, 6 and Normalized-Difference of Vegetation Indeks (NDVI). Field biomass was estimated using allometric Ketterings (2001). The biomass estimation model were developed using regression analysis by relating field biomass value and digital number of Landsat 8 Imagery. Selection of the best model based on the highest R2adj value, the lowest standard deviation value, the lowest bias value, and the lowest Root Mean Square Error (RMSE). Based on the result of model analysis to estimate biomass, obtained the best biomass estimate model, that is exponential model, Y = e (-27,40707 + 0,00461 X4 -0,00011 X5 - 0,00197 X6 + 50,79023 NDVI). The model selected based on the rating result had R2adj 78,8 %, standart deviation 0,227, bias 1,21 and RMSE 14,89.

Abstract

ABSTRACT Eurycoma longifolia Jack. including species from the family Simaroubaceae tree-shaped plants whose height can reach 10-15 m. E. longifolia Jack. is one of the potential medicinal plants and has high economic value if it is developed, because the extra roots of the earth pegs contain several medicinal compounds. Structure and pattern of distribution of individual populations of a species one alternative that can be done to support species conservation efforts. The area of ​​sampling area is 1 ha through 100 x 10 meter double plot vegetation analysis of 100 plots that are systematically located. In the condition of plant population structure, there are each individual growth stages most found in the 121 individual seedling stages and followed by 4 individual sapling growth stages. Through the calculation of the morisita index, it is known that the distribution pattern of the earth peg (E. longifolia Jack.) Groups with a morisita index value of 1.70. The distribution pattern of clusters shows that the presence of a plant will give an indication for similar plants, this is because individuals have a tendency to gather and look for environmental conditions that suit their needs.   Keywords: Eurycoma longifolia Jack, population structure and distribution patterns.   ABSTRAK Eurycoma longifolia Jack. termasuk spesies dari famili Simaroubaceae. Tumbuhan berbentuk pohon yang tingginya dapat mencapai 10-15 m. E.. longifolia Jack. adalah salah satu tumbuhan obat yang potensial dan punya nilai ekonomi tinggi jika dikembangkan, karena ekstra akar pasak bumi mengandung beberapa senyawa berkhasiat obat. Struktur dan pola penyebaran suatu spesies merupakan salah satu kajian yang perlu dilakukan untuk mendukung upaya konservasi spesies. Luas areal sampling 1 ha, pola penyebaran dipelajari melalui analisis vegetasi metode petak ganda ukuran 10 x 10 meter sebanyak 100 petak yang diletakkan secara acak pada tutupan hutan sekunder di areal lindung KSS PT. Wirakarya Sakti Distrik VII. Struktur populasi menunjukkan bahwa stadia pertumbuhan terbanyak pada stadia semai 121 individu dan diikuti stadia pertumbuhan pancang 4 individu. Melalui perhitungan indeks morasita diketahui bahwa pola penyebaran pasak bumi (E. longifolia Jack.) mengelompok dengan nilai indeks morasita 1,70. Pola penyebaran mengelompok menunjukkan bahwa hadirnya suatu tumbuhan akan memberikan indikasi untuk tumbuhan yang sejenis, hal ini disebabkan karena individu memiliki kecenderungan untuk berkumpul dan mencari kondisi lingkungan yang sesuai dengan kebutuhan hidupnya.   Kata kunci: Eurycoma longifolia Jack, struktur populasi dan pola penyebaran.

Abstract

Coral reef degradation on Samalona Island, Makassar City, has occurred as a result of anthropogenic pressures and changes in the marine environment. This condition directly affects the decline of ecological functions and the carrying capacity of marine ecosystems. This community service activity aims to rehabilitate coral reefs through a coral transplantation method based on collaboration between higher education institutions and the diving community. The methods employed include site surveys, fragmentation of healthy corals, attachment of coral fragments to artificial substrate media, as well as arrangement and tagging for monitoring purposes. The activity was conducted on November 25, 2025, in the waters of Samalona Island, involving lecturers from the Fisheries Science Study Program of Wira Bhakti University and partners from GGI SCUBA. The results show the successful installation of coral transplantation structures with hundreds of live coral fragments that have the potential to form new habitats for marine biota. This program is expected to gradually increase live coral cover and support the sustainability of marine ecosystems and marine tourism. This activity represents the implementation of the Tridharma of Higher Education in supporting coastal environmental conservation.

Abstract

Samalona Island is one of the leading marine tourism destinations in Makassar City that faces coastal environmental pollution problems due to the accumulation of waste, particularly plastic debris. Intensive tourism activities, limited waste management facilities, and low environmental awareness among local communities and visitors are the main factors contributing to the decline in coastal environmental quality. This community service program aims to improve the cleanliness of the island’s environment and to enhance the environmental awareness of both the local community and tourists regarding the importance of protecting coastal ecosystems through the Clean Island Action program. The methods employed include beach and shallow-water clean-up activities, environmental education, and evaluation of participant involvement and program outcomes. The activity was conducted on December 6, 2025, on Samalona Island, involving lecturers, students, local residents, and environmental volunteers. The results indicate a reduction in waste volume in coastal and beach areas, as well as increased participation and awareness among participants regarding waste management. This program has generated positive ecological and social impacts and has the potential to serve as a community-based model for sustainable coastal environmental management.

Abstract

The density of mangrove cover is one of the factors that influence changes in shoreline both accretion and abrasion. This study aims to determine the effect of changes in density of mangrove cover on shoreline changes in 1989-2018 in the Coastal Province of Jambi. The method used is the interpretation of Landsat satellite images in 1989, 2000 and 2018 using NDVI (Normalized Difference Vegetation Index) and overlaying images to see shoreline changes and DSAS (Digital Shoreline Analysis System) to calculate the area of change. The results showed that there had been a change in shoreline both accretion and abrasion in several locations that had different mangrove densities in the period 1989-2018. The results showed that accretion occured in 6 locations with an average change of Kota Sebrang 771 m, Tungkal Ilir 240.65 m, Kuala Betara 153.73 m, Mendahara 167.78 m, Kuala Jambi 169.35 m and Nipah 57.3 m, while abrasion occurs at 2 locations with an average change in Sabak Timur -41.8 m and Sadu -36.55 m. Where in the 6 locations that had accretion, mangrove density dominantly was in a close-densed and moderate state and only a few are in a low-densed condition. Meanwhile, the 2 locations that had abrasion were in a moderate state and have a low density mangrove forest.
