Abstract

Kelicung tree (Diospyros macrophylla) is a native tree species of West Nusa Tenggara. It is a slow-growing tree with very good wood ornament, strength, and durability properties. Symbiotic mutualism between kelicung and mycorrhiza has not been documented. Mycrorrhiza is a mutualism symbiosis between fungi and plant roots that could improve plant growth due to increase nutrient and water absorbtion. Therefore, the objective of this study is to investigate mycorrhizal symbiosis in kelicung roots. Soil and root samples were taken in the Rarung Special Purpose Forest Area at 0 – 20 cm depth. Isolation and identification of arbuscular mycorrhizal fungi used screening and centrifugation methods to identify spore density, diversity, abundance, and frequency. Furthermore, root staining and colonization of arbuscular mycorrhizal fungi were carried out by observing the structure of vesicles, arbuscules, hyphae, and spores on Kelicung roots. The research results showed that the average number of spores found was 846 spores/50 g of soil. Spores were identified in two genera: Glomus sp and Acaulospora sp. Glomus spores found were round, the colour of the spores was yellow, the spores did not react when Melzer's solution was dropped, and the spore walls of the Arbuscular mycorrhizal fungi of the genus Glomus consisted of 1-2 layers of cell walls. Observation of root colonization, no structures of root arbuscular mycorrhizal fungi were found in Kelicung. Keywords: Acaulospora sp., Arbuscular mycorrhizal fungi, Diospyros macrophylla, Glomus sp., Kelicung

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.

Abstract

Penelitian komposisi jenis, struktur tegakan dan produktivitas serasah di Hutan Penelitian Dramaga, Bogor, Jawa Barat belum pernah dilakukan sebelumnya. Oleh karena itu, penelitian ini penting dilakukan untuk menganalisis komposisi spesies, struktur tegakan dan produktivitas serasah, mengingat serasah merupakan komponen penting dalam siklus nutrisi di ekosistem hutan. Penelitian ini dilakukan mulai bulan Januari Tahun 2023 sampai dengan April 2023. Penentuan Stasiun Penelitian Observasi di lapangan ini Penelitian dilakukan pada dua petak pengamatan di Hutan Penelitian Dramaga yaitu petak nomor 21 tegakan (Hopea odorata) dan petak nomor 38 tegakan (Dipterocarpus retusus). Estimasi produktivitas serasah dilakukan dengan menggunakan serasah metode perangkap. Penelitian yang dilakukan pada Plot 21 ditemukan 27 jenis tumbuhan yang terdiri dari 13 jenis keluarga. Sedangkan pada petak 38 terdapat 30 jenis tanaman yang terdiri dari 15 famili. Blok 21 dan 38 mempunyai grafik tren yang membentuk kurva “J” terbalik. Karena jumlah spesies individu pada tahap regenerasi lebih besar daripada jumlahnya spesies individu pada tahap pertumbuhan tiang dan pohon. Dugaan produktivitas serasah di petak 38 lebih besar dibandingkan dengan petak 21, yaitu sebesar 47,67 g/m2/bulan sedangkan dugaan produktivitas serasah di  Petak 21 sebesar 28,37 g/m2/bulan. Komponen serasah yang paling dominan di kedua petak adalah komponen daun, yaitu sekitar 82,33% (petak 21) dan 76,41% (petak 38). Curah hujan dan kecepatan angin rata-rata tidak memiliki pengaruh yang signifikan pada fluktuasi serasah di kedua lokasi.

Abstract

Liquid Organic Fertilizer (POC) is a processed fertilizer resulting from the fermentation of organic materials, usually made from a mixture of agricultural and livestock waste. It is easy to apply, does not require a large amount, and the nutrient content that can be directly utilized by plants is an advantage of POC. Based on the dependence of residents on chemical fertilizers, which have a negative impact on the soil, this activity was finally carried out. This activity aims to overcome the problem of unutilized agricultural and livestock waste in Ciputri Village. The implementation of this activity is in Ciputri Village in July 2024, starting with socialization and continuing with a direct demonstration of POC. The results of the implementation of the activity increased public knowledge of POC to 90%. This activity provides new insights for the residents of Ciputri Village regarding the use of agricultural and livestock waste to deal with the problems of chemical fertilizers and waste management.

Abstract

This study aims to measure carbon reserves in horticultural plants planted on former tin mining land and compared with horticultural plants on non-mining land in Belinyu District, Bangka Regency. The time and place of this study were carried out from February 2023 to July 2023 in Gunung Pelawan Village, Bukit Ketok Village, Bangka Regency. The research method used was the purposive sampling method. The analysis method used percentage analysis. The results of the study showed that the carbon reserve content of plants plantedon former tin mining land was lower as an adaptation to former tin mining land that experienced drought stress and high light intensity but was not significantly different from plants planted on non-tin mining land. This is thought to be because the care given to plants on former tin mining land was quite good. Future research can be carried out by combining morphological, anatomical and physiological observations, as well as analysis of carbon reserve content in horticultural plants as a response to the former tin mining land environment.

Abstract

Andaliman breeding and regeneration (Zanthoxylum acanthopodium DC.) in its natural habitat tends to be slow and difficult. The purpose of this research was to determine the distribution pattern, spatial character, and potential suitable habitat for andaliman growth with a suitability model approach in Samosir island, North Sumatera. Andaliman distribution pattern based on the calculation of the Standard Morisita Index (Ip) shows various patterns. There are three categories of distribution pattern, depends on the Standard Morisita Index  The distribution patterns on each plot based on the calculation are: random (Location 1 – open area (Ip = 0.00)), uniform (Location 2 – plantation forest (Ip = -0.77); Location 3 –  open field (Ip = -0.09)), and clump (Location 4 – plantation forest (Ip = 0.36)). Analysis of habitat suitability for andaliman used spatial modelling with the Principal Component Analysis (PCA) approach. This method utilized ecological variables, i.e.: Bare Soil Index (BSI), slope, Digital Elevation Model (DEM), rainfall, Normalized Difference Moisture Index (NDMI), and Normalized Difference Vegetation Index (NDVI). The result is  69.8% of Samosir Island is suitable for andaliman, while 26.4% of it is considered as highly suitable habitat.
