Abstract

Utilization of marginal lands such as tidal land should be done to increase rice production as a solution of the decreasing productive land. However, rice cultivation in such land will be affected by low soil fertility, soil acidity and Fe toxicity. Fe-tolerant varieties are needed to overcome those problems. The objective of the research was to analyze the growth and production of Fe tolerant rice lines in tidal soil type C, Banyuasin, South Sumatera. Screening for Fe-tolerant character of 54 rice lines from the F8 RIL population derived from a cross between rice var. IR64 and var. Hawara Bunar using hydroponic technique under 1000 ppm Fe resulted 25 Fe-tolerant lines. The field test of 25 putative tolerant rice lines, at the tidal land in Banyuurip, Banyuasin, showed that the most lines grew better than that of var. Hawara Bunar parent. Several lines produced yield higher than that of var. Hawara Bunar parent. The field experiment resulted two rice lines, which were IRH108 and IRH195 that potential for further studies.

Abstract

Selaginella, a genus of Pteridophyte, is known as an herb that contains of several bioactive compounds. The growth and bioactive compounds of plant were affected by plant environment, such as media types. The objective of the research was to obtain an appropriate plant media for growing S. plana dan S. willdenovii, and its effect on the content of bioactive compounds. The experiment consisted of two factors, plant growth media and the species of Selaginella. The first factor consisted of eight plant growth media, i.e.: soil, rice husk, rice husk : soil = 1:1 (v/v), burned rice husk, soil : burned rice huks = 1:1 (v/v), burned rice husk : rice husk = 1:1 (v/v), burned rice husk : rice husk = 3:1 (v/v), and burned rice husk : rice husk = 1:3 (v/v). The second factor was two spesies of Selaginella, i.e.: S. plana and S. willdenovii. Ethanol extract of Selaginella was qualitatively analyzed for flavonoid, tannin, and saponin content. The result showed that both fresh and dry weights of Selaginella were influenced by the type of plant media, Selaginella species, and their interactions. S. plana and S. willdenovii grew best on medium containing soil: burned rice = 1:1 (v/v). The highest flavonoid content of S. plana and S. willdenovii was also obtained from the plant grown on the same media. Comparing to the bioactive compound content of natural plant, saponin content of S. plana and S. willdenovii was increased by the treatment of plant media. The treatment also increased tannin content of S. plana, but not of S. willdenovii.

Abstract

Aquilaria crassna is one of the Aquilaria species that could produce agarwood. agarwood production of A. crassna can be induced by microfungi as an inoculant. Ecological interaction between the host plant, wounding and inoculant in the formation of agarwood has not yet clearly. other factors like the plant ages, plant species, environ- ment also played important roles in the formation of agarwood. This research aimed to determine the influence of the combination between planting media and Acremonium sp. and Fusarium sp. to agarwood quality of Aquilaria crassna. The experiment was consisted of two factors, which were five planting media and two inoculants fungi i.e. Acremonium sp. and Fusarium sp. The observed parameters were the percentage of senescence leaves, color of wood, level of fragrant and terpenoid content. The best agarwood fragrant was produced by the seedlings that were treated with either combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp. or the combina- tion between husk charcoal media enriched with Hoagland modified solution and Fusarium sp.. The darkest color of wood was produced by the seedlings that were treated with combination of husk charcoal media enriched with NPK fertilizer and Acremonium sp., as well as for the same media with Fusarium sp.. during the experiment terpenoid could not be detected from the treated seedlings. Acremonium sp. caused more leave senescence than that of Fusarium sp..

Abstract

High methane oxidation activity of local isolated methanotrophic bacteria have a potent as methane gases reducing agent while combined with nitrogen fixing bacteria as paddy biofertilizer. The aim of the research was to evaluate the effectiveness of the bacteria as methane gases reducing agent and biofertilizer in paddy plantation. The research was arranged in a completely randomized design consisted of fertilizer types and watering system treatments with four replicates. The research showed that paddy shoot length was not affected by the treatment. On the other hand, both plant freshand dry weight, as well as the number of productive tiller were affected by interaction of fertilizer types and watering system. Fertilizer types affected grain per panicle and methane flux after fertilization. In the end of paddy vegetative stage, bacterial fertilizers were capable to reduce methane emission in different rate. The different result in methane flux was likely due to the interaction between soil local microorganisms and soil chemical component.

Abstract

Penelitian ini bertujuan untuk mengkaji kondisi ekosistem terumbu karang di Perairan Selat Nasik dan menganalisis kelayakan ekositem terumbu karang untuk dijadikan zona inti konservasi perairan laut di Kecamatan Selat Nasik Kabupaten Belitung. Penelitian ini dilaksakan pada  bulan Agustus-September 2016  di Pulau Piling dan Pulau Kera Kecamatan Selat Nasik Kabupaten Belitung. Metode yang digunakan dalam penelitian ini meliputi metode pemetaan partisipatif masyarakat dalam penentuan lokasi penelitian serta metode observasi untuk menganalisis kondisi ekosistem terumbu karang. Penentuan kesesuaian wilayah menggunkan metode penilaian data dan informasi, kriteria pertimbangan dan penentuan delineasi serta pengaturan kawasan konservasi dalam RZWP3K KKP 2014. Parameter yang diamati meliputi data sosial, data biofisik serta pertimbangan ekonomi.  Data hasil survey kemudian akan diolah menggunkan   softwere Microsoft excel 2010  untuk mendapatkan data atribut yang kemudian diolah kembali dengan menggunkan  softwere ArcGis 10.1 untuk menganalisis dan mengolah serta memodelkan kesesuaian secara spasial. Berdasarkan data penelitian terdapat dua kriteria kesesuaian yakni kriteria sesuai dan sangat sesuai.Pulau piling memiliki  area yang berkategori sesuai dengan luasan 10,45 Ha serta berkategori sangat sesuai dengan luasan  8,126 Ha. Sementara itu hasil pengamatan di Pulau Kera memiliki tingkat kesesuaian lebih baik dengan luasan 19,927 Ha area yang berkategori sesuai serta  45.92 Ha sangat sesuai. Luasan area di dua pulau tersebut  tersebut direkomendasikan sebagai zona inti ekosistem terumbu karang dalam wilayah konservasi perairan dengan total luas area rekomendasi di Perairan laut Selat Nasik sebesar  84,83 Ha.
