Abstract

The research was to obtain information about the combination of fertilizers in the production of arbuscular mycorrhizal inoculums of various depths. This research is using an experimental method. The research uses divided plot design (RPT) with a basic RAK pattern. The treatment factor consists of the main plot (peat depth 0-50 cm and 50-100 cm) and subplot is a combination of fertilizer (P1 = without fertilizing; P2 = NPK+rubberwood vinegar; P3 = NPK+peat vinegar; P4 = NPK+fern-root vinegar). Spore breeding process is ± 3 months. Hosts use sorghum with sterile sand media. The observation variable consisted of the percentage of root infections and the number of spores. Data analysis using ANOVA. Identification of spores based on morphology and Melzer reaction. The results showed that fertilization factors affected the number of spores. The number of spores without fertilization was higher, namely 1642,500 spores compared to combination fertilizers (NPK+fern-root vinegar was 707,667 spores; NPK+rubberwood vinegar was 606,833 spores; NPK+peat vinegar was 206,667 spores). The rate of 0-50 cm colonization without fertilization, NPK+peat vinegar, NPK+rubberwood vinegar is included in the high category. Then in the treatment at 50-100 cm without fertilizing, NPK+peat vinegar, NPK+fern-root vinegar infection rates are also high. The type of spore found is Glomus sp.1; Glomus sp.2; Glomus sp.3; Glomus sp.4. The results of the number of spores and the percentage of root infections showed that organic vinegar was known to not stimulate FMA sporulation, but organic vinegar did not inhibit FMA colonization.Keyword: Mycorrhizal, organic vinegar, peat depth, sorghum

Abstract

Kembang telang leaf extract is antimicrobial controlling pathogenic fungi in vitro. The purpose of the study was to determine the ability of the kembang telang leaf extract as an inhibitor of the growth of fungi that cause root rot and the concentration of the extract that was most effective. The research was carried out in the Silviculture laboratory Faculty of Forestry Universitas Tanjungpura for three months. The experimental method used a completely randomized design with treatments consisting of four concentrations, namely 0%, 3%, 6%, and 9%, with three replications. Telang flower leaf extract can inhibit Ganoderma sp. An inhibition zone looks more apparent than the Telang flower leaf extract area. The growth of fungal growth at the lowest concentration of 3% is the same as effectively inhibiting the growth of Ganoderma sp. The research results imply that the flower telang leaf extract has the potential as an antifungal against the Ganoderma sp.      Keywords: antimicrobial, extract, Clitoria ternatea, Ganoderma.AbstrakEkstrak daun kembang telang memiliki efek antimikrob dalam mengendalikan jamur patogen secara in vitro.

Abstract

Mangrove habitats play an essential role in the sequestration and storage of carbon. Mangroves absorb CO2 through photosynthesis to create carbohydrates stored as biomass in the leaves, stems, and roots. The objective of this study was to estimate the amount of mangrove carbon in the region of the 2012 planting year located in the mangrove forest area of Setapuk Besar Village. Biomass estimation employs a survey and non-destructing method by measuring tree stem diameter at breast height (DBH). According to the findings of this study, the mangrove forest area in Setapuk Besar Village can store up to 139.62 tons of carbon per hectare, equivalent to carbon dioxide (CO2) that can be absorbed at 511.98 tons/ha. Carbon stored above and below the soil surface and soil carbon contain respective values of 65.60 tons C/ha, 50.91 tons C/ha, and 23.11 tons C/ha.Keywords: Carbon stocks, forest biomass, mangrove forest, Setapuk Besar SingkawangAbstrakEkosistem mangrove mempunyai peran untuk menyerap dan menyimpan karbon. Mangrove melakukan penyerapan CO2 melalui proses fotosintesis untuk menghasilkan karbohidrat yang tersimpan dalam bentuk biomassa pada daun, batang maupun akar. Penelitian ini dilakukan bertujuan untuk mengestimasi jumlah karbon mangrove pada areal penanaman tahun 2012 yang terdapat pada kawasan hutan mangrove Kelurahan Setapuk Besar. Estimasi biomassa menggunakan metode survei dengan pengambilan data tanpa pemanenan yaitu mengukur diameter batang setinggi dada (DBH) atau pada batas tinggi 1,3 m dari permukaan tanah. Hasil yang diperoleh pada penelitian ini menunjukkan kawasan hutan mangrove Setapuk Besar dapat menyimpan karbon sebanyak 139,62 tonC/ha dengan jumlah karbondioksida yang mampu diserap sebesar 511,98 ton/ha. Jumlah karbon yang diserap merupakan karbon tersimpan di atas permukaan tanah, di bawah permukaan tanah maupun karbon tanah dengan nilai masing-masing yaitu 65,60 tonC/ha, 50,91 tonC/ha dan 23,11 tonC/ha.Kata kunci: biomassa hutan, hutan mangrove, karbon, Setapuk Besar Singkawang
