Abstract

Ekosistem mangrove memiliki fungsi ekologi yang penting sebagai penjaga stabilitas ekosistem pesisir. LPHD Sapat sebelum mendapatkan hak penguasaan hutan desa menghadapi tantangan pengelolaan berupa pemanenan hasil perikanan dengan racun dan setrum serta tekanan illegal logging mangrove. Setelah lima tahun mendapatkan pendampingan dari konsorsium pengelolaan pesisir perlu dilakukan penelitian untuk menganalisis kondisi biofisik ekosistem mangrove. Metode penelitian menggunakan kombinasi jalur berpetak, pengambilan sampel tanah dan air. Hasil analisis vegetasi menunjukkan bahwa nilai INP tertinggi ada pada jenis R. apiculata. Analisis kation dn anion tanah menunjukkan bawa kadar C/N senilai 16. Kualitas air menunjukkan bahwa konsentrasi Nitrat (NO3) sebesar 0,44 m.e./L dan Boron (B) dalam air melebihi baku mutu sebesar 2,51 mg/L yang dapat mempengaruhi kondisi ekosistem mangrove dan kehidupan biota. Kata kunci: LPHD Sapat, mangrove, INP, air, tana

Abstract

From 2015 to 2021, the Indonesian government collaborated with the Japanese government for the Forest Preservation Program in the Republic of Indonesia to restore the Matalawa NP ecosystem in degraded areas. This program has been running for five years, so it should provide changes to both social and forest conditions. This research aims to explain community perceptions, and social and forest conditions after the program. The research method includes interviews with locals and interpretation of satellite images. Analysis of interview data uses descriptive-quantitative methods, and interpretation of satellite images uses the NDVI. The research results regarding community perceptions of the program showed that their perceptions regarding the function and benefits of the program are classified as very good. Social changes occurred in the management of agricultural land, the intensity of coordination between the community and the Matalawa National Park, increasing public awareness to recognize the Matalawa National Park area, and attitudes toward mutual deliberation and cooperation. Image interpretation showed that vegetation in degraded areas is still dominated by low vegetation density. Medium and high vegetation density increased after the program. The ecosystem restoration program in Matalawa, NP, has positive implications for the community's social and environmental conditions. This impact can make the ecosystem restoration program a policy in managing Matalawa National Park. Keywords: Restoration, Community, Matalawa NP

Abstract

Gunung Dahu Research Forest is a forest area dominated by meranti species. The presence of human activity in forest areas has the potential to bring in invasive species. The presence of invasive plant species can have negative impacts on the ecosystem. This research aims to estimate canopy density in the Gunung Dahu Research Forest using the Normalized Difference Vegetation Index and its relationship with the diversity of invasive understory species to produce appropriate management recommendations. The canopy density class map was made using a desk study and the understorey data was taken using vegetation analysis. Correlation and regression tests were conducted to determine the relationship between NDVI values ​​and other variables. Based on the results of the NDVI analysis, three canopy density classes were obtained, low, medium, and high. The low canopy density class has the highest number of invasive species, while the high canopy density class has the least number of invasive plant species. The Poaceae family is the most found family with D. setigera as the dominant invasive species. There is a strong correlation between canopy density and NDVI values. Keywords: Dipterocarpaceae, Shorea sp., Poaceae

Abstract

Global warming is an increase in the average temperature of the earth's surface due to the effects of greenhouse gases, such as carbon dioxide. Global warming can be prevented by maintaining forest structure and increasing tree density in the forest, one of which is in the mangrove forest ecosystem through rehabilitation using bund techniques. This research aims to analyze the type composition and structure of mangrove stands, estimate carbon storage and carbon dioxide uptake in five-year-old mangrove stands in Jakarta. The research method used is vegetation analysis through simple random sampling. Data analysis was obtained through vegetation analysis, environmental factor analysis, and estimating carbon storage and carbon dioxide uptake in mangrove stands. The research results showed that the species growing at the research location were Rhizophora mucronata and Sonneratia caseolaris. Carbon storage in mangrove stands at the research location is 72.99 tonnes/ha, with a carbon dioxide absorption capacity of 267.63 tonnes/ha. Keywords: carbon stock, carbondioxide absorption, mangrove, guludan technique

Abstract

Stand structure will affect fuel characteristics in forest stands. Forest fuel characteristics have an important role in determining fire behavior in forest fires. The purpose of this study was to determine the effect of vegetation stand structure on the abundance and moisture content of fuels that affect the chances of forest fires in the Cilegon PLTGU conservation area. Vegetation analysis and measurement of fuel characteristics were conducted in two different stands, namely monoculture and polyculture stand. The parameters used to conduct vegetation analysis are tree height, first branch height, Diameter at Breast Height (DBH) and crown cover, while the parameters of fuel characteristics are abundance, thickness and moisture content of fuel. Based on the results of fuel characteristics research in monoculture stands resulted in abundance, thickness and moisture content of fuel respectively 11.35 tons/ha, 15 cm and 13,61%, while in polyculture stands resulted in abundance, thickness, and moisture content of fuel respectively 14.57 tons/ha, 10 cm and 16,46%. The moisture content in monoculture and polyculture stands is below the percentage value of 30% so that the two stands in the Cilegon PLTGU conservation area include areas that are still prone to forest fires. Keywords: forest fires, fuel, moisture content, stand structure

Abstract

Forest ecosystems can absorb greenhouse gases by absorbing CO2 from the air to store carbon in vegetation. The IPB Darmaga Campus Bamboo Arboretum is one of the green opn spaces on campus in an effort to reduce environmental pollution in the city. The aim of this research is to describe species composition, vegetation structure, estimate biomass potential, carbon storage and carbon dioxide (CO2) uptake, as well as describe soil properties in the Bamboo Arboretum, IPB Darmaga Campus. The method used is measuring diameter and height (trees, poles, stakes, dead wood and dead trees) as well as measuring the water content of undergrowth, seedlings, litter and twigs. Soil data collection was carried out using the purposive sampling method. The research results show that the species composition of the forest stands at the Bamboo Arboretum on the IPB Darmaga Campus is dominated by Hevea brasiliensis (rubber zone and Dipterocarpaceae zone), Bambusa blumeana (bamboo zone), and Swietenia mahagoni (mixed zone). The rubber zone is the zone with the highest value of biomass, carbon storage, and carbon dioxide uptake. The soil organic C content in the Bamboo Arboretum of the IPB Darmaga Campus in the Dipterocarpaceae zone, rubber zone and bamboo zone is high, while in the mixed zone it is medium. Keywords: Biomass, carbon, carbon dioxide, composition, necromass

Abstract

rainforest ecosystems. This study aimed to estimate the species composition and tree structure at various altitudes in GHSNP. The study used vegetation analysis through plots measuring 100 m × 20 m with three replications at three altitude ranges: <1000 masl (lowland), 1000-1500 masl (sub-montane), and >1500 masl (montane). At altitudes <1000 and 1000-1500 masl, Pinus merkusii and Schima wallichii are the dominant species, while Dacrycarpus imbricatus dominates at altitudes >1500 masl. The total volume of trees at each altitude range is 473.9 m3/ha, 221.67 m3/ha, and 201.11 m3/ha, respectively. As altitude increases, tree volume decreases. The species diversity index (H') value at all three altitudes is classified as medium, with a 1≤H'≤3 value. Keywords: Dacrycarpus imbricatus, Pinus merkusii, Schima wallichii, West Java
