Indonesia is the largest archipelagic country in world, with 17,000 islands of varying sizes and elevations, from lowlands to very high mountains, stretching more than 5000 km eastward Sabang Aceh Merauke Papua. Although occupying only 1.3% world’s land area, possesses third-largest rainforest second-highest level biodiversity, species diversity endemism. However, during last two decades, has been known as a deforestation, producer smoke burning forests land, carbon emissions. The aim this...
Soil organic matter (SOM) is a crucial component of soil, through which physical, chemical, and biological characteristics interact in local context. Within the forest category, conversion natural forests to monoculture plantations has raised concerns Indonesia over loss soil functions, similar agriculture. In forests, SOM can accumulate as part closed nutrient cycle with minimal losses; plantation forestry, decline recovery alternate time, associated larger losses. We reviewed existing...
To produce large volumes of biomass for implementing its green energy policy, the Government Indonesia has issued a short rotation plantation program number tree species including Calliandra calothyrsus (Meissn.). Optimum density and prompt harvesting are needed to maximise productivity, but information regarding both factors is insufficient. This study aimed investigate optimum growth spacing ideal felling age largest economically sustainably. Experiments were arranged on one hectare land,...
The most serious impact after exploiting coal by opened peat mining is acid mine drainage phenomenon. This an oxidation of sulphide minerals releasing sulphate that generate the environment acidity. study was aimed to observe ability reducing bacteria (SRB) isolated sludge paper mills in decreasing ex-coal content. Before inoculating onto soil, SRB incubated sterilized organic matter for 4 days. Organic inhabited mix with soil (1:3 v/v). As a control series mixed non inoculated experiment...
Microbes are important rhizosphere constituents for providing nutrients in the soil. This study analyzes dynamic of soil functional microbes' populations on land managed as an agroforestry (AF) system. The AF system consists a 2-years old auri tree combined with several crops, i.e., wild grasses, peanuts (Arachis hypogaea), pigeon pea (Cajanus cajan), and maize (Zea mays). Soil samples were collected from each then analyzed their chemical properties such N, P, K, pH, C organic contents....

Teknik pertambangan terbuka pada lahan bekas tambang batubara di Sumatera Barat mengakibatkan vegetasi penutup tanah hilang, pemadatan tanah, kahat unsur hara, reaksi masam, top soil tipis, rendah bahan organik, tekstur buruk, toksisitas mineral, kandungan logam tinggi dan mengganggu aktivitas mikroorganisme tanah. Mikroba seperti Bakteri Pereduksi Sulfat (BPS) dapat dimanfaatkan untuk perbaikan sifat kimia dalam mendukung revegetasi batubara. Tujuan penelitian adalah mendapatkan isolat BPS...
Kaliandra ( Calliandra callothyrsus ) merupakan salah satu jenis yang dapat dikembangkan sebagai kayu energi karena selain memiliki nilai kalor tinggi. Inokulasi dengan rhizobium dan mikoriza telah umum dikenal meningkatkan mutu bibit. Tujuan penelitian ini adalah untuk mengetahui infektivitas efektivitas terhadap pertumbuhan bibit kaliandra umur 5 bulan. Perlakuan diberikan 1 ml, 2 g per kombinasi keduanya serta perlakuan tanpa mikroba kontrol. Rancangan digunakan Acak Lengkap. Hasil...
Cutting trees removes all parts of their photosynthetic area, which affects rhizosphere assembly. However, information regarding the underground alteration process after tree cutting is insufficient. This study aimed to observe fate both root exudation and microbial community following cutting. The included 540 Calliandra calothyrsus Meissn. experimental layout was a completely randomized block design with 3 blocks (cutting age) × 2 not cutting) 180 trees. Composite soil samples were...
The shoddier succeed land revegetation particularly caused by least adaptability of the seedlings planted on this site. To encourage their growth and survival rate it can be achieved means do inoculation with compatible functional microbes such as rhizobium, Psolubilizing bacteria (PSB) and/or arbuscular-mycorrhiza fungy (AMF). This reserach is aimed to formulate most inoculant support A. crassicarpa seedlings. Compatibility study carried out in RCB design 3 replications, each contain 5...
Salah satu hambatan yang dihadapi dalam kegiatan rehabilitasi lahan bekas tambang adalah tingginya akumulasi logam tanah. merupakan salah jenis prioritas dikembangkan hutan tanaman industri. Jenis ini juga mempunyai banyak keunggulan untuk ditanam pada revegetasi tambang. Penelitian bertujuan mengetahui pengaruh perlakuan ameliorasi tanah dan inokulasi mikroba terhadap pertumbuhan Sebelum ditanami, diameliorasi dengan bahan organik (1:1 v/v) di inkubasi selama 15 hari. Selanjutnya ditanami...
Mine tailings generally have low fertility, and also high concentration of metals. Amelioration with soil organic is one proper efforts. Sludge pulp paper mills can be an alternative source. This research aimed to improve chemical properties mine tailing. The study was conducted in randomized completely design dosages 25 50% tailing added into pond dump. Observation N, P, K, pH CEC were the days 0, 5, 10 15 after incubation, whereas content S, Pb, Cd, Cu, Fe CN measured 7 incubation. result...
Pruning is a removing some parts of the tree canopy, either for improving shape or increasing shoot productivity. It can be implemented in yield management commodities that are harvested its biomass, such as tea kilemo. This activity interferes plant growth, hence affect root secretion. Consequently, it alters soil microbe populations rhizosphere. paper observes impacts pruning on fluctuation exudates (soil sugar) and rhizosphere communities 2-years-old Kilemo (Litsea cubeba L. Pers.). Tree...
Taxus sumatrana (Miquel) de Laub is a crucial species of medicinal tree that has not received enough research and commercial use in Indonesia despite being listed as one the country's protected plant species. Almost all parts genus contain Taxane diterpenoids, very efficacious substance fighting cancer, especially breast cancer. The study aimed to reveal composition habitat T. by conducting vegetation analysis making 13 plots measuring 20 m x for an inventory trees with diameter 10 cm up....
Plantation forests have been strongly established in Indonesia, with Acacias and Eucalyptus as the most common species. Using a single species large plantation may affect its sustainability because of threat from biotic abiotic factors. The soil microbiome is key to an ecological process associated both However, research aiming understand microbial communities Indonesia still limited. We analyzed bacterial six sites three conservation areas representing natural forest ecosystems. produced...
Abstract Study aims to observe the best practice in optimizing land productivity for successing rural food and energy sovereignity.
