Abstract

Gunung Sasak di Kabupaten Lombok Barat merupakan bagian dari kawasan hutan tropis dataran rendah yang berperan penting dalam menjaga keberlanjutan ekosistem dan menyediakan sumber daya air bagi masyarakat sekitar. Kawasan ini belum banyak dikaji secara ilmiah, terutama terkait struktur komunitas vegetasi pada hutan kemasyarakatan. Penelitian ini bertujuan untuk mengevaluasi ekostruktur tegakan berdasarkan parameter keanekaragaman jenis (H’), kemerataan (E’), dan kekayaan jenis relatif (R’) pada berbagai tingkat pertumbuhan: semai, pancang, tiang, dan pohon. Metode yang digunakan adalah inventarisasi vegetasi dengan plot kuadrat dan analisis deskriptif kuantitatif. Hasil menunjukkan bahwa nilai H’ tertinggi terdapat pada tingkat pohon (2,02) dan terendah pada tingkat semai (1,36), dengan kemerataan (E’) berkisar antara 0,69 hingga 0,75. Seluruh tingkat pertumbuhan memiliki nilai R’ < 3,5 yang mengindikasikan kekayaan jenis rendah. Kombinasi nilai-nilai tersebut menunjukkan bahwa struktur tegakan cenderung stabil pada strata pohon, namun regenerasi alami di strata bawah masih terbatas. Hal ini menandakan potensi kerentanan terhadap gangguan ekologis dan perlunya intervensi pengelolaan untuk memperkuat rekrutmen jenis lokal. Penelitian ini memberikan dasar ilmiah bagi strategi konservasi dan pengelolaan hutan berbasis masyarakat yang berkelanjutan di wilayah hutan musim Nusa Tenggara Barat.

Abstract

Pencemaran logam berat di ekosistem pesisir telah menjadi persoalan multidimensional yang tidak hanya mengancam keberlanjutan ekologis, tetapi kesehatan masyarakat pesisir. Tujuan penelitian adalah untuk mengetahui konsentrasi dan kemampuan akumulasi logam Kadmium dan Besi oleh Rhizophora mucronata di Pelabuhan Lembar, Lombok Barat. Metode yang digunakan adalah systematic sampling with random start sebanyak 24 plot pada tiga stasiun. Sampel berupa akar dan daun diuji kandungan logamnya di Laboratorium BRMP. Hasil menunjukkan konsentrasi tertinggi logam berada di akar, yaitu 590,93 ppm (Fe) dan 9,76 ppm (Cd), sedangkan pada daun sebesar 43,89 ppm (Fe) dan 2,08 ppm (Cd). Kandungan logam ini telah melebihi ambang batas baku mutu. Nilai faktor translokasi (TF) menunjukkan bahwa R. mucronata bersifat fitoekstraktor terhadap Cd (TF > 4) dan bersifat fitostabilisator terhadap Fe (TF < 1). Kerapatan pohon R. mucronata berhubungan signifikan dengan konsentrasi Fe (p < 0,05) dengan kontribusi sebesar 80,3% (R² = 0,803), tetapi tidak signifikan terhadap Cd (p > 0,05; R² = 13,1%). Parameter lingkungan tidak menunjukkan hubungan signifikan terhadap konsentrasi logam, meskipun memberikan sedikit pengaruh terhadap akumulasi Cd dan Fe.

Abstract

The objective of this community service activity was to ascertain the location and extent of customary forests in Bayan Village, with the intention of subsequently preparing a map delineating the boundaries of these areas. The preparation of the map was conducted through a participatory approach, which involved the village government, customary leaders, representatives of indigenous communities, youth leaders, and communities situated in close proximity to the customary forest area. The location of the service was determined through the use of purposive sampling, with the following considerations taken into account: Bayan Village is notable for its extensive customary forest area, ranking among the largest in North Lombok Regency. However, there has been no data update related to the customary forest area since 2005. The data sources employed in this activity encompassed both secondary and primary data, which were subsequently classified into two distinct categories: primary data, comprising boundary digitization results, satellite imagery, village boundaries, village profiles, and pertinent literature; and secondary data, obtained from various sources, including satellite imagery, village boundaries, village profiles, and related literature. The data were analyzed using ArcGIS 10.8.2 software, resulting in a map visualization of the customary forest areas. The mapping results demonstrate that the Bayan Village Customary Forest is divided into four distinct areas: Bangket Bayan, Mandala, Pangempokan, and Tiu Rarangan. The total area of the customary forest in Bayan Village is 82.02 hectares, representing a decrease of 1.18 hectares from the 2005 mapping results, which recorded 83.2 hectares

Abstract

Watershed degradation poses a serious threat to water availability, ecosystem sustainability, and human well-being. This study aims to identify and analyze the spatial distribution patterns of three key water-regulating plant species Pterospermum javanicum, Ficus spp., and Dendrocnidae decumana in the upstream area of the Babak Watershed, Lombok, Indonesia. Field data were collected through exploratory surveys and analyzed using the Average Nearest Neighbor (ANN) method in ArcGIS 10.8. The results reveal distinct spatial patterns: D. decumana exhibits a random distribution (R = 0.925), while Ficus spp. (R = 0.667) and P. javanicum (R = 0.698) show clustered patterns. These patterns reflect ecological adaptations such as tolerance to environmental heterogeneity or vegetative reproduction strategies. Despite differences, all three species significantly contribute to watershed hydrology by enhancing infiltration, reducing surface runoff, and stabilizing soil. Spatial analysis of vegetation distribution provides essential insights for data-driven watershed management and supports targeted conservation strategies in ecologically sensitive upstream zones.

Abstract

The mangrove ecosystem in the Labuan Tereng area needs to be protected and preserved. Mangrove ecosystems have an important role as carbon absorbers and play a role in environmental detoxification through their ability to absorb heavy metals in their surroundings. This study seeks to analyze the ability of Rhizophora apiculata to absorb and retain cadmium (Cd) and iron (Fe) concentrations in the Labuan Tereng mangrove habitat. A systematic sampling approach with a random start was applied, involving 24 plots distributed over three designated stations. Roots and leaves were sampled at each station. Heavy metal concentration analysis for Cd and Fe was conducted at the BSIP Laboratory for Agricultural Instrument Standardization. The study results reveal that root tissues contained the highest concentration levels, namely 615,23 ppm (Fe) and 0,98 ppm (Cd). Therefore, in leaf organs as large as 35,85 ppm (Fe) and 1,09 ppm (Cd). The concentration of heavy metals in R. apiculata has surpassed the permissible limits set by environmental quality standards. Result T-test shows that no significance between Fe and Cd metal in a distance of 0-100 and 100-200 m from the coastline. The translocation factor value of Rhizophora apiculata has phytoextraction properties with a TF value>2 for Cd metal, while for Fe metal, it has phytostabilization properties with a TF value<1. The influence of density on the level of trees and saplings does not have a significant relationship with Cd and Fe metals, where the t-count is > 0.05 and the effect is very weak on Cd and Fe metals.

Abstract

Labuan Tereng Village is a place where mangrove vegetation grows and develops. The location close to the harbor sheet makes the mangrove ecosystem damaged by port activities. High port activity can disrupt the condition of mangrove ecosystem development in Labuan Tereng Village. This study was conducted to evaluate mangrove health by looking at canopy cover or canopy density using the Hemispherical Photography method analyzed using Landsat 9 and Sentinel 2A to assess the extent of relationship between mangrove canopy cover and images. The findings revealed that the mean mangrove cover density value of 66% which is included in the medium category. Statistical analysis of several vegetation indexes with mangrove cover obtained the highest linear regression results in the SAVI model with a value of 0,41 for Landsat 9 images and 0,65 for Sentinel 2A images. The results of image data analysis on Sentinel 2A show a smaller pixel size value and contain more pixels so as to produce better and complex data analysis when compared to Landsat 9 imagery.

Abstract

The area of mangrove ecosystems in West Nusa Tenggara Province continues to decline each year. One of the threatening factors that substantially contribute to such condition is socioeconomic activities of human beings in fulfilling their needs. An effort that can be made primarily to preserve the mangrove ecosystem is to quantify the economic value of environmental services provided by the mangrove ecosystem as a whole, so that the existence and sustainability of the mangrove ecosystem could be maintained. This research aims to calculate the total economic value of mangrove ecosystem services which indicate the four categories of ecosystem services including supporting services, provisioning services, regulatory services and cultural services. The research was carried out using a survey method by collecting data and information from location of this study to obtain actual data regarding the existence of the mangrove ecosystem. The results of the analysis show that the total economic value of mangrove ecosystem environmental services is 963,888,060/year. This value is divided into provider services (supply services) amounting to Rp. 153,002,250, regulatory services (arrangement services) Rp. 598,339,702, supporting services (support services) Rp. 2,243,250, and cultural services (cultural services) Rp. 210,308,857. The magnitude of the total economic value of mangrove ecosystem environmental services can be a reference for the government in determining compensation for services if there is degradation to mangrove ecosystem resources in the area.
