Abstract

Pemanasan global (global warming) merupakan salah satu bahasan penting yang menjadi perhatian banyak pihak di seluruh dunia. Salah satu upaya penurunan emisi karbon dapat dilakukan dengan pengurangan emisi karbon. Tanah merupakan salah satu penyimpan karbon terbesar dalam ekosistem daratan. Dari berbagai macam jenis tanah, terdapat beberapa tanah yang mampu menyerap dan menyimpan karbon dengan baik, salah satunya seperti Tanah Gambut dan Tanah Mangrove. Tujuan dari penelitian ini dibuat adalah untuk mengetahui seberapa banyak dan besar perbedaan cadangan karbon dari kedua jenis tanah tersebut, Metode yang digunakan berupa literatur review dari berbagai sumber seperti jurnal, buku, artikel ilmiah, dokumentasi, internet, maupun kepustakaan lainnya. Hasil penelitian menunjukkan bahwa cadangan karbon pada tanah Gambut berkisar antara 1.172- 9.055,922 ton/ha-1. Sedangkan cadangan karbon pada tanah mangrove berkisar antara 163,08 - 2.561,90 ton/ha. Sehingga dapat disimpulkan bahwa tanah gambut lebih mampu menyimpan cadangan karbon dengan kapasitas lebih tinggi dibandingkan dengan tanah mangrove. Namun hal ini dapat juga ditentukan oleh beberapa faktor lain. Kata kunci: Tanah, Tanah Gambut, Tanah Mangrove, Cadangan Karbon

Abstract

Acacia crassicarpa is one of the Fabaceae family which has been widely recommended for planting in the context of rehabilitation of critical lands as well as HTI development, due to its fast growth, wide adaptation, and resistance to unfavorable conditions. Acacia crassicarpa in the nursery is often attacked by various pests, one of which is the Paracoccus marginatus. Efforts to the use of Annona muricata leaf control Paracoccus marginatus currently carried out generally use chemical methods. extract is an alternative that can be used as an environmentally friendly pesticide. This study aims to determine the utilization of Annona muricata leaf extract to control Paracoccus marginatus in Acacia crassicarpa nursery and to determine the best concentration of Annona muricata leaf extract for the mortality rate of Paracoccus marginatus. This study used a completely randomized design method (CRD) consisting of 4 treatments and 4 replications with concentrations of vegetable pesticide solutions. P0 = control (without Annona muricata leaf extract), P1 = 10 g/l of water, P2 = 20 g/l of water, P3 = 30 g/l of water. The results showed that the botanical pesticide from Annon muricata leaf extract concentration of 30 g/l of water is the best concentration in controlling Paracoccus marginatus with the fastest initial time of insect death is 2.5 hours (2 hours 30 minutes), 50% fastest time of death (LT50) is 8.5 hours (8 hours 30 minutes) and total mortality amounted to 90 %.

Abstract

The plant species commonly used in Industrial Plantation Forests as raw material for pulp and paper is Eucalyptus pellita. One of the quality seeds of E. pellita is produced from superior clones by vegetative propagation, namely shoot cuttings. There are research results that show the propagation of certain clones has the highest Survival Rate when treated without using additional hormones. Therefore, it is necessary to conduct research on the propagation of E. pellita seed cuttings without using hormones. The results of the physiological analysis of E. pellita shoot cuttings showed that each parameter observed, namely IAA hormone content, C-organic, and N value, showed non-linear results with shoot age treatment. The results of measuring shoot length, number of nodes, and distance between nodes showed linear values with shoot age treatment. The results of observations of total Survival Rate, total roots and shoots showed that the 18 day shoot age treatment had the lowest value compared to other treatments. At the age of 2 weeks, it showed that the 21 day shoot age treatment had the fastest root growth ability compared to other treatments. Based on the results of height and diameter measurements at 12 weeks, it shows that 21 day old shoots have the best growth and Survival Rate so that they can be used as a basis for determining the age of shoots in the production of clone 148 seedlings on an operational scale. Keywords: E. pellita, physiological, propagation, hormone

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
