Abstract

The rehabilitation of mangroves depends on the availability of high-quality, sufficiently prominent seeds. Currently, a lot of mangrove nursery activities continue to employ traditional techniques, which results in low-quality and slowly growing seedlings. The mangroves of Jakarta were selected because they represent a heavily polluted mangrove ecosystem on Java's northern coast, whereas the mangroves in Kebumen, on Java's southern coast, are in the opposite situation. This study proposed to find an approach to supply Indonesia's mangrove restoration projects with adequate seeds. An experimental approach with a complete randomized design and a factorial pattern was used. The variables tested were planting media and three kinds of mangroves: Rhizophora mucronata, Ceriops tagal, and Bruguiera gymnorrhiza. Mangroves from Jakarta are treated with mud, soil media, or a mix of them. A mixture of mud, husk, and husk charcoal is used for six treatments planting media for mangroves from Kebumen. The mangrove seedlings' growth, biomass, and chlorophyll content are the dependent variables. ANOVA was used to evaluate the data with a 95% confidence level, and Duncan's comparison of means test followed. The growth of mangrove seedlings was discovered to be impacted by media type, while the chlorophyll content, dry biomass of roots, stems, and leaves were not affected by this factor. Three species of mangroves differ regarding growth rate, biomass of roots, stems, and leaves, and chlorophyll content. In order to support Indonesia's efforts to rehabilitate mangroves, this research can offer understanding regarding how to select and employ the best media to effectively produce high-quality seeds.

Abstract

Ceriops tagalĀ (Perr.) C.B. Rob can be found in Baluran National Park, Kepulauan Seribu National Park, Karimunjawa National Park, and Segara Anakan Cilacap in Java and its surrounding areas. These locations have different demographics and environmental conditions. Plant species found in different geographical areas have varied genetic structures and morphological traits as a result of their adaptability to their environment. The goal of this study is to evaluate the morphological and genetic differences between the four populations of C. tagal in Java and its surroundings. Internode length, leaf length, leaf width, petiole length, and leaf area were the morphological characters used. The Internal Transcribed Spacer (ITS) region is used as a molecular marker. The UPGMA dendogram was used to analyze the morphological similarity, and multidimensional unfolding analysis was used to determine which character most determined the grouping. Mega X software was used to analyze genetic variation using the neighbor-joining approach, while Arlequin 3.5 software was used to estimate genetic variation within and among populations. The results of this study showed that the population of Baluran National Park has features or is distinct from the other three populations based on morphological and genetic characters; this could be because of variations in geographic conditions, and that population diversification was aided by a combination of genetic and physical divergence, restricted gene flow, and local adaptation.

Abstract

Mangrove merupakan salah satu ekosistem langka dan khas yang terdapat hanya 2 % di seluruh permukaan bumi. Ekosistem mangrove terluas di dunia berada di Indonesia. Ekosistem mangrove berperan dalam bidang ekologi, ekonomi serta sosial dan budaya. Hutan mangrove setiap tahun terus mengalami penurunan luas dan perubahan tingkat kerapatan akibat kerusakan. Salah satu tumbuhan yang terdapat di ekosistem mangrove adalah genus Acanthus. Genus Acanthus merupakan tumbuhan yang dapat digunakan sebagai bioindikator kerusakan mangrove dan dapat berkembangbiak secara vegetatif dan generatif. Tujuan dari penelitian ini adalah menghitung kerapatan dan distribusi genus Acanthus pada area kerusakan mangrove di Segara Anakan bagian barat Cilacap. Penelitian dilakukan dengan metode survei dengan teknik pengambilan sampel vegetasi mangrove purposive sampling pada 11 stasiun terpilih di Segara Anakan bagian barat Cilacap. Nilai kerapatan dan Pola distribusi genus Acanthus dianalisis menggunakan Surfer 15 untuk mendapatkan pola distribusi genus Acanthus. Nilai kerapatan dan faktor lingkungan dianalisis menggunakan BIOENV dengan Primer 5 kemudian dianalisis secara deskriptif. Nilai kerapatan genus Acanthus pada 11 stasiun terpilih yaitu 15.520 ind.ha-1. Pola distribusi genus Acanthus di Segara Anakan bagian barat Cilacap yaitu pola distribusi mengelompok (aggregate).

Abstract

Ceriops tagal is a major mangrove species that contributes significantly to the mangrove environment. Ceriops tagal is a species of mangrove that supports a variety of marine organisms, including fish, shrimp, nematodes, and other biota, as well as maintaining the mangrove ecosystem's stability. A nursery is required in the recovery process. The addition of husk and husk charcoal to nursery media can enhance water, air, and plant nutrient absorption space. The objective of this study is to (1) determine how different nursery media with a mixture of husk and husk charcoal affect mud media, and (2) find which nursery media has the best influence on biomass and chlorophyll content in C. tagal mangroves. This study began with the propagules of C. tagal being planted in different composition growing media with husk and husk charcoal, and then calculating the biomass in the root, stem, leaves, and hypocotyl, as well as the chlorophyll content in the leaves of C. tagal organs, using an ANOVA test. Then, for the wet biomass of the root, dry biomass of the stem, root, and wet and dry biomass hypocotyl of C. tagal, do an honest significant difference test of 5%. According to the findings, adding husk and husk charcoal to nursery media can increase the dry biomass of the root and stem, as well as the wet and dry biomass of the hypocotyl in C. tagal organs. Media 5 (mud + husk charcoal in a 2:1 ratio) and media 6 (mud + husk + husk charcoal in a 1:1:1) were the best media for increasing the biomass of the C. tagal in each organ. Environmental factors such as the pH content of the medium influence the increase in dry biomass of the root and stem, as well as the wet and dry biomass of the hypocotyl. Keywords: biomass, Ceriops tagal, chlorophyll, nursery media
