Abstract

Jabon (Anthocepalus cadamba Roxb.) is one of the fast-growing species that naturally spread in some areas of Indonesia. Known as well adapted to some types of soil, and attributes to a quite high of economical prospects value. Interaction of Arbuscular Mycorrhiza Fungi (AMF) symbiotic involve not only between fungi and plant’s root but also involving supporting organisms (bacteria). This bacteria capable to stimulating the development of mycorrhizal hyphae namely as Mycorrhiza Helper Bacteria (MHB). The aims of this research was to discover of bacterial isolates that can stimulate the development of AMF in Jabon seedling and to examine the effectiveness of MHB isolate and AMF toward Jabon growth. The experiment was conducted in Completely Randomized-split splot design with two factors. The main plot was AMF with two levels; without AMF (M0) and with AMF respectively. Bacteria as the sub-plot with 19 levels consist of the control (B0), Isolate of Glomus sp with coding B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12, B13, B14, B15, B16, B17, and B18 respectively. Our experiment result showed that AMF inoculated of Jabon seedling had significantly effect on root colonization and root dry weight. The average of root colonization was 20.2%. Root dry weight increased 4.69% compared to control. Bacteria were suspected as MHB has not provided significant resultsKey words: arbuscular mycorrhizal fungi, jabon, mycorrhizal helper bacteria

Abstract

Jernang rattan is produced from a palm species surface layer of fruit by resine with dark red. Jernang rattan cultivation has several obstacles due to limiteation of seed availability, low seed production, recalcitrant seeds, and slow seedling growth. In order to accelerate seedling growth and providing a good quality of seedlings, an inoculation of seedling with Arbuscular Mycorrhizal Fungi (AMF) and addition of bio-organics in growing media is needed. This study aimed to analyze the growth responses of Daemonorops draco Blume seedlings inoculated by AMF and addition of bio-organic. The research design used was completely randomized design which consists of two factors, AMF (M) consists of four levels (M0 = Without AMF, M1= AMF collection in the mycorrhizal laboratory M2= Indigenous FMA from rattan rhizosphere and bio-organic (B) consisting of five levels (B0= Without bio-organic, B1= dose of bio-organic 5%, B2= dose of bio-organic 10%, B3= dose of bio-organic 15%, B4= dose of bio-organic 20%). The results showed that control soil media could not to support the growth of Rattan Jernang Seedlings. The plant treated by interaction (M2B2) increased plant height by 140.76%, diameter by 106.57% and biomass by 591.22% compared with control.

Abstract

Jernang rattan is produced from a palm species surface layer of fruit by resine with dark red. Jernang rattan cultivation has several obstacles due to limiteation of seed availability, low seed production, and has technical problems in the form of hard fruit skin. This study aimed to studied the effect of the interaction of atonic concentration and soaking time for jernang rattan seeds on their germination. There were two factors in this study: Atonic concentration treatment (5 levels) and soaking time (3 levels). The results show that increasing the germination of Jernang rattan seeds can be done using an atonic concentration of 15 ppm and soaking for 1 hour. This is because it provides better results on research variables.

Abstract

Penelitian ini bertujuan untuk menganalisis erosi tanah di Daerah Aliran Sungai (DAS) Lawo dengan menerapkan model Revised Universal Soil Loss Equation (RUSLE) yang diintegrasikan dengan teknologi penginderaan jauh dan Sistem Informasi Geografis (SIG). Strategi pemodelan yang digunakan mencakup pendekatan spasial melalui survei lapangan serta simulasi hidrologi menggunakan perangkat lunak ArcSWAT. Dari hasil penelitian menunjukkan bahwa rata-rata laju kehilangan tanah tahunan di DAS Lawo adalah sebesar 13,02 ton/ha/tahun, yang diklasifikasikan dalam kategori ringan. Variasi nilai erosi ditemukan pada berbagai tutupan lahan, dengan angka terendah pada hutan sekunder (0,13 ton/ha/tahun) dan nilai tertinggi pada area pertanian lahan kering bercampur semak (4,45 ton/ha/tahun). Tingginya laju erosi pada area tertentu sangat berkorelasi dengan kondisi topografi lereng yang terjal serta manajemen lahan yang belum optimal. Meskipun distribusi Tingkat Bahaya Erosi (TBE) secara keseluruhan didominasi oleh kategori sangat ringan (33,43%), terdapat sekitar 25,88% wilayah DAS yang telah masuk dalam kategori berat hingga sangat berat. Hasil ini menegaskan bahwa penggunaan lahan dan faktor topografi memegang peranan vital dalam dinamika erosi, sehingga diperlukan strategi konservasi tanah dan air yang terpadu untuk memitigasi degradasi lahan di wilayah tersebut

Abstract

Soil is an important component of forest ecosystems because it acts as a provider of nutrients, a support for vegetation, and a regulator of biogeochemical cycles. Variations in the physical and chemical properties of soil are greatly influenced by vegetation cover and soil depth. This study aims to analyse the chemical properties of soil in two types of vegetation cover, namely dense and moderate cover, in the Riau University Arboretum, which was determined using the Normalised Difference Vegetation Index (NDVI) method. Soil samples were taken at three depths (0–10 cm, 10–20 cm, and 20–30 cm) to determine the vertical variation in soil chemical properties. The parameters analysed included pH, organic carbon (organic C), total nitrogen (total N), phosphorus (P₂O₅), and potassium (K₂O). The results showed that soil pH was in the acidic category, ranging from 4.43 to 5.21. Organic carbon content was higher in the surface layer than in the lower layers, with the highest value of 5.14% in medium cover. Total N content was low in all samples (0.11–0.25%), indicating a limitation of nitrogen as a factor restricting vegetation growth. The nutrient elements P₂O₅ and K₂O tended to be higher in the surface layer, especially in dense cover (P₂O₅ = 26.66 mg/100 g; K₂O = 24.56 mg/100 g). In general, dense cover was able to maintain nutrient availability better than medium cover, although medium cover had relatively higher organic C content on the surface. These findings confirm that vegetation cover plays an important role in maintaining soil quality, and the preservation of dense vegetation needs to be optimised to support soil fertility and the sustainable conservation function of the arboretum.
