Carbon stock is one of the essential types of ecosystem services that are provided by vegetation. Land use has significant effects both directly and indirectly on vegetation cover and strongly influences the carbon stock within the ecosystem. In this study, we have investigated the effect of land cover changes on the carbon stocks at the sub-watershed of Sumber Brantas, Batu city, East Java. This research was conducted at the Junrejo, Batu and Bumiaji districts of Batu city. Land cover classes were determined from satellite imagery. The carbon stock was measured at plot and landscape level using RaCSA. The results showed that forest conversion into plantation forest (pine, Teak, Albizia chinensis, Anthocephalus cadamba) or agricultural land caused losses of the above-ground C-stock of ~50 Mg ha-1, while losses of the underground C-stock were ~20 Mg ha-1. Tree biomass contributes about 60% of the C-stock on average, while the understorey and necromass contribute C-stock about 2% and 5%, respectively. Mixed forest has a total C-stock as much as 316.64 Mg ha-1, followed by plantation forest (247.19 Mg ha-1), farmland and scrubland i.e. 51.57 Mg ha-1 and 12 Mg ha-1,respectively. As the consequences of forest conversion into cropland (2008~2012), the Sumber Brantas sub-watershed (139,447 ha) has been lost its C-stock as much as 0.83 Mg ha-1 yr-1, equivalent to 3.04 Mg CO2 ha-1 yr-1. This study showed that C-stock will be maintained by managing and planting woody plant which has high tree biomass.

Community awareness in healthy life is increasing by consuming nutritious food through such as fruit. So it is necessary for increasing the availability of fruit either by cultivation expansion or technology development. The production life of papaya crop approximately three years only, so that replanting takes relatively fast. But there is some limitations mainly the availability of suitable seedling (age and uniformity). For improving the availability of suitable papaya seedling can be used gibberellin as growth regulator substance. But gibberellin in pure analysis limitations are expensive, not always available, and high technology in application. The aim of the research was to test of shallot juice (1 kg of shallot bulbs destroyed by juicer) as gibberellin substitute for improving papaya seedling. The experiment was conducted at terrace house, consist of percentage and speed of germination and growth of seedling observation after seed soaked 2 hours in shallot juice several concentration treatment. Test of the germination percentage and speed conducted for 10 seeds on pastur paper in petridish (11.5 diameter) as germination media. The experiment for growth seedling was arranged in randomized completely design which the treatments are: seed soaked in water, soaked in 5, 10, 15, dan 20 ml l-1 shallot juice concentration, and soaked in gibberellin 10 ppm. Each of the experiment unit consist of 8 seedlings which planted on trypot (composite of plastic pots by size 5.5x5.5 cm at surface, 5.5 cm height, and 2,5x2,5 cm at the base, each of traypot consist of 32 pots). So in each of tray pot there are 8 experimental units, each of experimental unit repliclated 3 times. Traypot and petridish at terrace house shaded by woven plastic 65%, by size 2.5x1.5x2.0 m (length, width, and height). Yield of the research showed that shallot juice potential as gibberellin replacement in papaya nursery. Response of papaya seed (percentage and speed of germination) and seedling (length of root, stem diameter, number of leafs, leaf area, and weight of biomass) to 15 ml l-1 shallot juice equal with gibberellin 10 ppm.

The study aimed to determine the effect of gelatinisation of feed ingredients as a energy sources by steaming and amino acid supplementation and its use in rations of sheep on performance improvements, has been done in the cage experiment Jatikuwung, Department of Animal Husbandry UNS for 4 (four) months, starting from June until September 2009. Analysis of feed materials is done in laboratory of Nutrition and Feed Science, Faculty of Agriculture UNS. Twenty sheeps with the initial's body weight ranged from 10 + 0.4 kg, were divided randomly into 6 treatments. The rations consisted of king grass and concentrate with the ratio = 60: 40 (DM basis). Treatment applied is P1: rice bran, P2: steamed rice bran, P3: steamed rice bran + MHA, P4: Onggok, P5: Onggok steamed and Q6: Onggok steamed + MHA. Each treatment is repeated 4 times and each test consisted of one sheep. Anova is used to determine the effect of treatment variables were observed and DMRT to test the real difference between treatments. The results showed that steaming and MHA supplementation did not affect the consumption of rations, ADG and FCR, this situation illustrates that the treatment can not be applied to improve the consumption, resulting in an PBBH, although there is a tendency to increase consumption and PBBH especially in rice bran. But the real protein consumption (P <0.05) influenced by treatment. The protein consumption is higher of Rice bran (P <0.05) compared onggok. Decrease in protein consumption significantly (P <0.05) followed by PBBH trend, this shows an improvement of protein quality steaming and supplemented with MHA so that there is also a tendency increase protein efficiency ration. Steaming rice bran and supplemented MHA and its use in rations provide a good influence on growth and protein quality of sheep rations.
