Land ownership is an important factor for the Indonesian population who lives still depend on agriculture. Ownership of land is not only important for agriculture but also to assess the needs of others in their social life. So, land not only serves as an asset but can also function as a commodity that can be traded, it also serves as a social status for their owners. Land transactions, especially in rural areas, expansive effect on tenure and rural incomes, which may have implications for the emergence of a variety of land tenure in the countryside. The results PATANAS (Panel Petani Nasional) 2010 conducted by the Center for Social and Enonomi of Agriculture, over the period 2007 to 2010 shows that the country has decreased, especially in Java land, while the villages outside Java are experiencing the opposite of a sharp increase in ownership. This indicates that the Panel Petani Nasional for 3 (three) years, indicating that that in that period there has been a fluctuation in land ownership. Whilst the change is not so prominent, but the tunakisma (lendless) in rural areas are likely to continue to grow. This certainly has implications to changing socio-economic conditions for rural communities concerned, same with the changing status of tenure communities. This paper is part of research that focuses on PATANAS 2010 villages based producer of rice paddy fields as national Keywords: Pattern Dynamics Control, Wetland, Rural Areas

The purpose of this study to determine the role of gibberellins in enhancing the quality of soybean seeds that have experienced deterioration / decline. This research is using a complete randomized group design (RKTL) two factors. The first factor is pengusangan soaking seeds with 20% ethanol. P0 = Without soaking, P1 = Immersion 15 minutes. P2 = Immersion 30 minutes. The second factor is the provision of gibberellins with gibberellin soaking treatment for 2 hours. G0 = without soaking gibberellins, gibberellin soaking G1 = 20 ppm. Each treatment was repeated 3 times. Analysis of data using analysis of variance and to know the difference between treatments, conducted LSD (Least Significant Difference). Each with a real level of 5%. The results are: 1). Application gibberellins showed no recovery of seed deterioration, because pengusangan seeds with ethanol has not shown any significant effect on seed deterioration. 2). Application giberelin the percentage of seed germination and seed vigor percentage lower that 66, 62% and 44.00% compared with that without the application of gibberellins 91.22% and 66.67%, due to the application of gibberellins, sprouts many broke. Might be due to cell division and enlargement of the seed is not offset by the formation of cell walls, so that the cell wall is weak and vulnerable to fractures sprouts 3). Application gibberellins produce a longer hypocotyl length 10.69 cm compared to that without the application of gibberellins that is 7.94 cm. 4). Application gibberellins produce root length is shorter on the 7.73 cm compared to 8.10 cm without the application of gibberellins Keywords: Deterioration, Soybean, Gibberellin

This research was conducted to study the effect of ration with certain ratio of forage-concentrate and the time of feeding on productivity of male local rabbits. Eighteen rabbits were used in Completely Randomized Block Design with factorial pattern 3 x 2. The rabbits was devided in three groups based on its body weight. Body weight of the first group, the second group, and the third group respectively 1.085 -1.185 g, 1.200-1.365 g, and 1.380-1.530 g. There were two factors in this design. The first factor were ration with certain ratio of forage-concentrate (R). In that factor there was three treatmens, ration with ratio of forage-concentrate 60%:40 as the first treatment (R1), 50% :50% as the second treatment (R2), and 40%:60% as the third treatment (R3). The second factor was the time of feeding (W). There were two treatments in this factor, the time of feeding on day (at 06.00 am. up to 06.00 pm.) as the first treatment (W1) and on night (at 06.00 pm. up to 06.00 am.) as the second treatment (W2). The result indicated that there was no interaction (P>0.05) between ration with certain ratio of forage-concentrate and the time of feeding on feed consumption, average daily gain, and feed efficiency. The factor of ration with certain ratio of forage-concentrate affected (P<0.05) feed consumption, however didnâ€™t affect (P>0.05) average daily gain and feed efficiency. Feed consumption of the rabbits that got treatment ration with ratio of forage-concentrate 40:60% (R3) was the lowest. The time of feeding didnâ€™t affect (P>0.05) feed consumption, average daily gain, and feed efficiency. Keywords: Forage, concentrate, ration, rabbits
