Abstract

Gunung Raung merupakan gunung yang terletak di tiga kabupaten di Jawa Timur, yakni Kabupaten Jember, Bondowoso, serta Banyuwangi. Salah satu pemanfaatan lahan di lereng barat Gunung Raung digunakan sebagai lahan agroforestri berbasis kopi. Penggerek buah kopi merupakan hama yang sering ditemui oleh petani kopi di Desa Rowosari dan masih sulit dikendalikan. Salah satu pengendalian yang dapat dilakukan adalah dengan menciptakan vegetasi yang mendukung keberadaan musuh alami khususnya Dolichoderus sp. Penelitian ini bertujuan untuk mengetahui pengaruh berbagai jenis agroforestri terhadap populasi semut hitam (Dolichoderus sp.). Penelitian ini dilakukan dengan metode analisis vegetasi untuk mengetahui karakter vegetasi dan menggunakan alat vakum untuk mengumpulkan semut. Jumlah populasi semut Dolichoderus sp. pada lahan wanatani sederhana berbasis kopi terdapat 6.520 individu, sedangkan pada lahan wanatani kompleks berjumlah 1.330 individu. Data yang diperoleh kemudian dianalisis menggunakan analisis regresi dan korelasi. Hasil penelitian menunjukkan bahwa keanekaragaman dan kekayaan tumbuhan bawah mempunyai hubungan yang negatif, sedangkan hubungan antara keanekaragaman dan kekayaan tumbuhan bawah menunjukkan hubungan yang positif. Kata kunci: agroforestri, tanaman kopi, Dolichoderus sp.

Abstract

The quality of seedlings reflects of the genetic and physiological quality of plants. Good seedlings are an important factor in the success of planting. This study aimed to assess the quality of seedlings produced at the BPDAS Solo Permanent Nursery. The assessment of seedling quality criteria is based on the Regulation of the Director General of RLPS Number P.05/V-SET/2009 and SNI 8420:2018. Three species of seedlings are assessed, namely trembesi, balsa, and soursop. The origin of the seeds of the 3 species of seedlings tested did not come from a certified seed source or had seed quality information so they had not passed the test for the seed origin criteria. The physical quality requirements for seedlings include the percentage of normal seedlings and the average of special requirements for the three species of seedlings tested in the category of passing the test and first quality (P). This showed that BPDAS Solo Permanent Nursery produces seedlings that meet standards and are ready to be planted in the field. Keywords: seedling quality, raintree, balsa, soursop, permanent nursery

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

Mycorrhiza is a form of symbiosis between fungi and plant roots that can increase the absorption of plant nutrients, especially phosphorus (P). Mycorrhizal diversity is influenced by environmental conditions and the type of host plant. This study aims to assess mycorrhizal diversity in Gunung Halimun Salak National Park, particularly in the core zone (ZI) and rehabilitation zone which comprises of two ecosystems type, rehabilitation zone with reforestation (ZRR) and rehabilitation zone with agroforestry (ZRA). A total of 75 soil and root samples were taken from each location then used to observe spore diversity, spore density and arbuscular mycorrhizal fungi (AMF) colonization. The results showed that there were 8 genera of AMF found in the three locations, namely Acaulospora, Entrophospora, Dentiscutata, Diversispora, Gigaspora, Glomus, Sclerocystis and Scutellospora. The highest spore density was found in the ZI at 22.66 spores/g of soil. The Glomus and Acaulospora were the highest genera in terms of relative frequency in all sites study (100%). Glomus had the highest relative abundance in all three sites including the ZI 52.38%, ZRR 54.16% and ZRA 47.8%. AMF colonization was negatively correlated with potential P content, but positively correlated with light intensity. The highest level of colonization was found in ZRA at 59.07%.

Abstract

Mycorrhizosphere is the area around the roots of plants that have mycorrhizae and generally contain many microorganisms. The aim of this research was to analyze the number of Aarbuscular Mycorrhizae Fungi (AMF) spores, populations, and morphological characteristics of bacteria in the mycorrhizosphere of trembesi seedlings growing in post-mining media in organic pot containers. The experimental design used was a Completely Randomized Design (CRD) with split plot design consisting of 3 factors, namely AMF, organic pot composition, and size of potting material. The results showed that the interaction of AMF inoculation factors and pot composition had a significant effect on the number of AMF spores, the percentage of root colonization, and the number of bacterial colonies. The combination of treatment with AMF inoculation using a pot composition of 45% newspaper, 35% compost (bokashi), 0% Cocopeat, 0% Rock phosphate was able to increase the number of AMF spores in organic pots and media as well as the percentage of root colonization. The dominant character of the bacterial colony is milky white, round in shape, smooth/flat edges, and convex elevation.

Abstract

Land use changes in forest areas for specific purposes (KHDTK)in Mandiangin, South Kalimantan affect the vegetation diversity loss and physical soil properties changes. This study aimed to analyze vegetation characteristics and soil physical properties across different land cover types (rubber/RB, bare land/BL, simple agroforestry/SA, complex agroforestry/CA, and natural forest/NF) on various slope positions (above, middle, and bottom). The method used was purposive sampling for vegetation analysis in 5 land cover types and 3 slope positions with three replications (45 plots). Parameters observed for soil physical properties were Bulk Density (BD), Particle Density (PD) and Porosity The total number of individuals in NF, SA, CA, RB, and BL in order is (1,713,333, 1,035,000, 768,333, 444,167, 375,000 individuals/ha individuals). The dominant species in natural forests are alaban and bangkal gunung, complex agroforestry namely rambutan, durian, nangka, avocado, matoa and mahoni, simple agroforestry namely jengkol, kemiri and mahoni, rubber plantations namely karet, bare land namely karamunting. The highest bulk density was found in natural forest and rubber (1.21 g/cm³). The highest porosity was found in bare land (53.34%) and the lowest in rubber (44.57%). These findings indicate that variations in land cover and slope significantly affect soil physical properties, which is important for sustainable land management. Keywords: Agroforestry, land use covers, soil physical properties

Abstract

Leaf blight that attacks teak (Tectona grandis L.f.) can reduce the plant's productivity. Leaf blight control can be done through dark septate endophyte (DSE). This study aims to test the ability of DSE GS2 and DSE TM fungi to inhibit the growth of pathogen colonies that cause leaf blight in vitro. Antagonistic tests of DSE against pathogen that cause leaf blight were carried out through a modified double culture test. The results of the antagonistic test showed that DSE GS2 and DSE TM could inhibit the growth of pathogens. The best inhibition results were demonstrated in the second double culture test after DSE was grown for seven days because DSE could grow stably and produce metabolite compounds. DSE TM had the best inhibition compared to DSE GS2. The mechanism of DSE inhibition against pathogens occurs through physical contact and the production of metabolite compounds characterized by the inhibition zone around the DSE. Keywords: Biocontrol, colony, Preventive, Rhizoctonia sp.
