Abstract

Critical land is caused by unsustainable land use and has an impact on decreasing the function of the land ecosystem. An effort to rehabilitate critical land can be carried out through the implementation of four-dimensional agroforestry (4D Agroforestry). The aims of this research were i) to design a 4D Agroforestry design, and ii) to analyze the growth of ginger (Zingiber officinale), pepper (Piper nigrum), cardamom (Amomum cardamomum), and grass jelly (Cyclea barbata) under the shade of mahogany (Swietenia mahagony) . The number of plants used was 67 ginger seeds, 44 pepper seeds, 187 grass jelly seeds, and 65 cardamom seeds, so the total was 363 plant seeds with an observation duration of 4 WAP. Implementation of 4D Agroforestry is an alternative effort to optimize land management by utilizing 4 dimensions, namely i) length dimension by planting mahogany, ii) width dimension by planting grass jelly (C. barbata), iii) height dimension by planting pepper ( P. nigrum), cassava (M. esculenta), ginger (Z. officinale), and cardamom (Amomum cardamomum), as well as iv) time dimensions for short-term production (production from cassava, grass jelly, ginger and cardamom plants ), medium (production from pepper plants), and long (production from mahogany wood) to achieve sustainable production. Cardamom plants produced the best growth in the parameters of height increase (15.28 cm) and percent survival (98.46%) after 4 WAP. Keywords: agroforestry, farmers, rehabilitation

Abstract

According to Law No. 5 of 1990 Grand Forest parks are conservation forests that function as nature conservation areas for the purpose of collecting natural and non-natural plants and animals, which are used for research, science, education that support cultivation, culture, tourism and recreation. The purpose of this study was to analyze the composition and structure of the stands in TAHURA Wan Abdul Rachman, Lampung in protection blocks, utilization blocks and collection blocks. The results of this study indicate that the number of species in the collection block is higher than the utilization and protection block. The species that dominated the three research blocks were Dalbergia latifolia, Durio zibethinus, and Tristaniopsis merguensis. The index value of species diversity (H') in the three blocks at the level of seedlings, saplings, poles and trees is in the medium criteria with a value of H'> 2, while the richness index is in the low category. Stratification of Tahura Wan Abdul Rachman's crown is in stratum B and C. Keywords: composition, dominant index, dominant species, vegetation structure, weath index

Abstract

Forest fires occurred in Mount Ciremai National Park (TNGC) area during the period from 2011 to 2022. These fires led to secondary succession, altering the composition and structure of the forest stands. This research aims to analyze the floristic composition and vegetation structure of the mountain forest post-fire. Data collection was conducted through vegetation analysis in two land cover types: primary forest and post-fire 2019 forest. The research shows a difference in the number of tree species found in the post-fire forest, and the number of plant species were recorded in sampling plots are totally 90 species of the 43 families. The ground cover plant was dominated by the species Orthosiphon aristatus, while the seedling and sapling stages were dominated by Cinchona calisaya, the pole stage was dominated by Oreocnide rubescens, and the tree stage was dominated by Macaranga tanarius. The plant diversity of the primary forest was relatively higher and the composition of tree stage in the primary forest and the post-fire 2019 forest were close to similar. The horizontal structure of the forest stands showed an inverted J-shaped curve, while the understory trees dominated the vertical structure. Keywords: fire, floristic composition, mountain forest, Mount Ciremai National Park, stand structure

Abstract

Oil palm plantations have always been attached to the issue of ecosystem degradation, both biotic and abiotic. Insects as one of the biotic factors in the ecosystem often have important roles such as pollinating agents and soil improvers. This study explored the effect of distance between oil palm plantations and forests on the diversity of soil surface insects. This study used the pitfall trap method to collect insect samples and analyze ecosystem richness, diversity, evenness, and similarity. It was found that differences in distance had an impact on insect abundance, composition and diversity. The ecotone ecosystem, which is at the closest distance to the forest, showed higher insect abundance and richness compared to the oil palm ecosystem. This creates higher values of ecosystem diversity and similarity between the two ecosystems. However, distance may also limit insect movement between ecosystems. Results from the study may provide new insights into the distance factor in understanding the ecological dynamics of insects between oil palm and forest ecosystems, which may contribute to more effective conservation planning. Keywords: Distance, ecotone, forest, insects, oil palm

Abstract

Kebakaran lahan gambut menjadi salah satu permasalahan serius dari pengelolaan lahan gambut. Salah satu faktor yang memengaruhi kebakaran lahan gambut ialah tinggi muka air (TMA) yang menurun sehingga perlu dilakukan pemantauan secara real-time. Data yang dikumpulkan adalah data TMA yang diperoleh dengan menggunakan sensor submersible dan manual. TMA yang didapatkan pada lahan gambut di desa Tangkit Baru mengalami kenaikan ketika curah hujan meningkat, berbeda dengan TMA di desa Pematang Rahim yang cenderung tidak mengalami kenaikan ketika terjadi hujan yang cukup lebat. Hasil t-test pada perbandingan pengambilan sampel TMA menunjukkan nilai 0,052 yakni lebih dari 0,05 yang menandakan tidak ada perbedaan antara kedua pengukuran. Perbandingan antara pengambilan dengan sensor submersible dengan manual memiliki selisih 0,1-1 cm, sehingga hal ini menunjukkan bahwa estimasi TMA dengan sensor submersible dapat diterima, namun perlu dilakukan pemeliharaan lebih lanjut untuk mendapatkan data yang lebih akurat. Kata kunci: Lahan gambut, sensor, tinggi muka air tanah

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
