The assessment of soil fauna in three different ecosystems namely teak forest, home garden and fallow paddy field had been studied in Pati, Central Java. The soil fauna was collected using a soil corer of 20 cm diameter to the depth of 0-15 cm from 5 randomized points in the above ecosystems. The soil fauna was t$en extracted in a Berlese funnel extractor. Soil fauna in the home garden showed the highest abundance (2 940 individual m--), followed by teak forest (2 340 individual m-?) and fallow paddy (1 790 individual m-?). The home garden had also a higher soil fauna diversity (2.06) compared to the teak forest (1.82) and fallow paddy (1.67). In terms of soil fauna biomass, the teak forest had a higher value (961 mg m-3 compared to the home garden (368 mg m-3 and fallow paddy (309 mg m"). In these three ecosystems, two fauna groups, i.e. Collembola and Acari were the most abundant animals. Poor vegetation cover tends to reduce the population of soil fauna in the fallow paddy. field, whereas vegetation, found in the home garden and teak forest protected the soil surface from direct sunshine and maintained soil moisture. This condition presumably provided a more favorable habitat for soil fauna. Thus, vegetation cover appears important to maintain soil moisture and soil living-organisms. Keywords: soil fauna, abundance, diversity, ecosystem, vegetation cover

A study on population dynamics of microarthropods (oribatids and collembolans) in rainfed paddy field ecosystem inPati, Central Java was undertaken with the aim to evaluate which group of soil microarthropods that dominated in each phase of rain fed paddy field. The soil fauna was collected using a soil corer of20 cm diameter to a depth of 0-15 cm, every 30 days.In the fallow, soil fauna was sampled from 4 randomized points per plot, meanwhile in the rice field phases (dry seeded rice and transplanted rice), it was sampled from 4 randomized points in the fields and in the bunds, respectively. per plot. Soil microarthropods in each season were then extracted in a Berlese funnel extractor.During the fallow phase, the dominant soil microarthropods were Oribatida of the Acari (1200 individual m,l) andsome groups of Collembola, namely Hypogastruridae (/200 individual m:2), Entomobryidae (500 individual m,l) andIsotomidae (620 individual m,2), meanwhile Sminthuridae of Collembola did not appear in this phase. In the rice phase,however, Sminthuridae of the Collembola occurred in high numbers, i.e., 860 individual m,2 (field) and 6/0 individual m,l(bund).Regarding the population dynamics of soil microarthropods in rainfed paddy field, we can assumed that oribatids and some groups of collembolans (Hypogastruridae, Entomobryidae and Isotomidae) play an important role in improving the nutrient availability during the fallow phase. meanwhile the Sminthuridae of collembolan seemed to play such role in the rice field phase. more than the other soil microarthropods.

Oribatids are one of the important fauna groups in the soil. They have an important role in the decomposition of organic matter in the soil. The objection of this research was to study population dynamics of Oribatids through determining the abundance and diversity of Oribatids and to know the effect of environmental factors on Oribatids in oil palm plantation at Bajubang, Batanghari, Jambi. Soil and litter samples were taken from four different locations (25 m x 25 m) and from each location three samples were taken from litter lanes and open lanes, respectively (the size was 16 x 16 cm with a depth of soil is 5 cm). The samples were extracted using Kempson extractor. Identification of Oribatids was done to the family level and the diversity of Oribatids was measured using Shannon’s diversity index. The population dynamic of Oribatids showed a fluctuation in the sampling period. When rainfall increased >200 mm did not follow by increasing abundance and diversity (number of the family) of Oribatid mites. When rainfall between 100 – 200 mm was the optimal condition for Oribatids so abundance and diversity (the number of the family) of Oribatids increased. But, when rainfall <100 mm especially in February 2014 (the lowest rainfall 1 mm), abundance and diversity (number of the family) of Oribatids was lowest (330 individual m-2; 7 families) compared to another month. It was assumed that Oribatids may migrate into the deep soil to avoid a harsh environmental condition. Abundance and diversity (number of the family) of oribatids were significantly higher in litter lanes (4,560 individual m-2; 25 families) than in open lanes (1,570 individual m-2; 14 families). The availability of litter in the litter lanes was higher than in open lanes. In this research, There are 3 families that most abundance and always found on the sampling period, they are Scheloribatidae, Mycobatidae and Galumniidae. Keywords: Abundance, diversity, oil palm plantation, Oribatids, soil fauna

Endophytic diazotrophic bacteria are free-living atmospheric dinitrogen fixing bacteria that lived and colonized between living plant cells and do not contribute pathogenic effects to its host. The ability of endophytic diazotrophic bacteria in providing nitrogen as a nutrient for crop plays an important role in reducing the dependency of inorganic nitrogen fertilizer. The aim of this experiment was to study the ability of endophytic diazotrophic bacteria isolate to stimulate vegetative growth of oil palm seedlings at four levels inorganic nitrogen fertilizer application. Experiment was conducted at the greenhouse IPB Campus, Cikabayan, Darmaga with the altitude of 250 m above sea level and at the Soil Fertility Laboratory, the Departement of Soil Science and Land Resources, Faculty of Agriculture, Bogor Agricultural University (IPB) and at the Laboratory of Biotechnology, Indonesian Sugarcane Research Centre (P3GI) Pasuruan, East Java. This experiment using Completely Randomized Block Design (CRBD) consisted of two factors with three replications. The first factor was inorganic nitrogen levels consisted of four levels (0, 50%, 75% and 100% of the recommended dose). The second factor was inoculation with endophytic diazotrophic bacterial isolates consisted of four levels; without inoculation, inoculated with isolate 1, isolate 2 and isolate 3. The results of the experiment showed that the inoculation with bacterial isolate 2 without N fertilizer application gave the best results to increase the diameter of the palm weevil, palm height, and dry weight. In addition to that, the application of endophytic diazotrophic bacterial isolate was able to promote vegetative growth of palm oil seedling.

Acari dan Collembola merupakan mikroarthropoda yang hidup di tanah dan lapisan serasah. Dalam ekosistem mikroarthropoda berperan aktif dalam proses dekomposisi yaitu dalam fragmentasi bahan organik sehingga dapat mempercepat penghancuran bahan organik. Penelitian ini bertujuan untuk mempelajari kelimpahan dan keanekaragaman mikroarthropoda pada berbagai mikrohabitat kelapa sawit. Penelitian ini terdiri dari 3 tahap yaitu pengambilan sampel, ekstraksi dan identifikasi fauna tanah. Plot pengambilan sampel diambil dengan jarak 50 x 50 m yang terdiri dari 5 titik, setiap titik terdiri dari 11 mikrohabitat. Sampel diambil pada beberapa mikrohabitat kelapa sawit yaitu tanah dengan jarak 0 m; 1 m; 3m dari tanaman kelapa sawit, gawangan kompos, pelepah pada ketinggian 30 cm; 90 cm; 150 cm, epifit pada ketinggian 30 cm; 90 cm; 150 cm dan tonggak. Sampel diambil pada bulan Januari 2014. Ekstraksi mikroarthropoda menggunakan Kempson Extractor, sedangkan identifikasi dilakukan sampai tingkat subordo untuk Acari dan famili untuk Collembola. Kelimpahan dan keanekaragaman mikroarthropoda dihitung menggunakan rumus kelimpahan menurut Meyer dan indeks keanekaragaman Shanonn (Shannon’s diversity index). Untuk mengetahui perbedaan kelimpahan dan keanekaragaman mikroarthropoda di berbagai mikrohabitat digunakan analisis sidik ragam satu arah (one-way ANOVA) dan uji jarak berganda Duncan. Hasil penelitian menunjukkan bahwa kelimpahan mikroarthropoda tertinggi ditemukan pada pelepah dan epifit. Kelimpahan Acari tertinggi ditemukan pada mikrohabitat epifit dengan ketinggian 30 cm yaitu 4,408 individu m-2, sedangkan kelimpahan Collembola tertinggi ditemukan pada mikrohabitat pelepah dengan ketinggian 150 cm yaitu 6,173 individu m-2. Kondisi mikroklimat pada mikrohabitat pelepah dan epifit lebih sesuai untuk kehidupan mikroarthropoda dibandingkan dengan mikrohabitat yang diteliti.

Adding organic fertilizer such as vermicompost can be done to overcome the deficiency problem of soil organic matter. One of the worm species which can be used in vermicomposting is Eudrilus eugeniae. Purpose of this research was to know how the combination of cow dung and rice straw impacts vermicompost quality from organic carbon, N, P, total K, urease enzyme activity and vermicompost production. Treatment that used in this research is randomized completely design with 4 treatments. The treatments are P1: feed 400 g of cow dung, P2: feed 400 g of rice straw, P3: feed 280 g of cow dung and 120 g of rice straw, and P4: feed 140 g of cow dung and 60 g of rice straw. The research result shows that real treatment impacts all parameters on the produced vermicompost. Production result is determined by ratio value of output/input (O/I). Quality and production of vermicompost on P4 is a treatment with the best result. It is because the combination of cow dung and rice straw gives a relatively complete macro nutrient result and the higher feed dose will gives higher vermicompost production.
