ABSTRACTPest and natural enemy population in three different rice cultivation in Sukamandi RegionSome on limiting factors in rice production include the cultivation system and pest damage. To suppress the damage, several control techniques have been applied, such as technical culture. The aim of this study was to gain information on population and pest damage, as well as natural enemy population in three different rice cultivation systems. The study was arranged in Randomized Block Design with three treatment and 9 replications. The treatments were: 1) organic rice cultivation, 2) semi organic, and 3) farmer technique. The used rice variety was Inpari 30. The plot size was 6 m x 90 m. The variables observed included population and pest damage, natural enemy population, and rice yields. Thirthy two rice hills were observed randomly in diagonal direction, with 2 weeks interval from two weeks after transplanting until harvest. The data were analyzed by analysis of variance (Anova) and the difference among the treatments was evaluated with Duncan multiple area test at 5% level. The results showed that brown plant hoppers population on organic rice cultivation is lower than semi-organic rice cultivation and farmer technique, but there were no difference of natural enemy population among treatments. The lowest yield was obtained from the organic rice cultivation (2.67 t/ha).Keywords: Rice cultivation, Pests, Natural enemiesABSTRAKBeberapa faktor pembatas produksi padi diantaranya adalah cara budidaya dan adanya serangan hama.

Utilization of maize waste as the organic matter sources in agricultural land couldn’t be directly applied, caused by late decomposition prosess. An effort to accelerate of maize waste decomposting needed bioactivator. The research was conducted in green house and Bajeng Research Intallation from March to August 2015. The research was arranged in randomized block design using isolate bacteria and fungus just one or theier combining ie: three bacteria  (B7.1,E7.7and E7.11), three fungus (M7, O5, P7), and four bacteria-fungus combining(B7.1+O5, B7.1+M7, E7.7+P7, B7.1+E7.7+O5), EM4 and N,P,K fertilizer(200,45,60) ha-1as the check treatment. Just one isolate fertilized by 75 percent N,P,K while combine isolate fertilized by 50 percent N,P,K recommended. The results indicated that just one decomposer E7.7 produced high enouugh grain yield not siqnificantly different by N,P,K (200,45,60) and five other just one treatment (E7.11,B7.1,M7 and O5), however siqnificantly different with combining decomposer (B7.1+O5, E7.11+M7, E7.7+P7, B7.1+E7.7+O5 and EM4). This mean that using stalk plus leaf waste maize compost could be subtitution in organic fertilizer untill 25 percent. Meanwhile combining decomposer was good enough for composting stalk and leaf of maize waste ie. isolate B7.1+O5 and E7.7+P7 although not significntly different with the other combine isolate including EM4. Thise case related by applied 50 percent N,P,K inorganic recommended fertilizer did not sufficient to supporting maize nutrient.Key Words: Decomposer, Bacteria, Fungus, Composting,Maize waste

Turnover of organic matters to the soil can increase the efficiency of chemical fertilizers, improve the plant growth and sustain the environment. Field experiment was carried out in the Buyut Udik Village, Gunung Sugih District, Central Lampung from May to August 2009.  Rice straw was composted by three kinds of decomposer (bioactivator A, B, and C). Rice straw compost (2 Mg ha-1) was applied to the paddy-field soil that was planted by rice (Oryza sativa) of Ciherang Variety. The experiment was arranged in a randomized block design with three replicates. The results showed that application of rice straw compost reduced the numbers of empty grain per tiller compared to control (without compost) in which control had the highest percentage of empty grain (15.9%). The application of rice straw compost that was decomposed by bioactivator A gave the highest numbers of grain per panicle and yield per plot as followed 162.5 seed and 33 kg plot-1, respectively.  Application of various rice straw composts that were decomposed by three kinds of bioactivator increased the rice grain up to 13-26% compared to control.
