Intensively land use for biomass production without applying sustainable and sustained plant farming technique in District Selo potentially causes soil damage. Determination of soil potential damage and soil damage status has been set by the central government through Government Regulation No. 150 year 2000 on Soil Damage Control for Biomass Production. The research method used was a descriptive survey with a stage-setting soil potential damage by overlay thematic maps and the determination of the status of soil damage using matching methods and relative frequency score. Results obtained in the land area of the District Selo potentially medium damage 1,439.3 hectares and 1,988.8 hectares of high potential damage. After survey and laboratory analysis of soil samples at the site results that the Status of Soil Damage categorized light (R.I) with a score relative frequency of each 8. Total area that included minor damage divided into 3,296.97 hectares with limiting factors texture and permeability and 59.32 hectares with limiting factors permeability.

Degraded land is the land that has lost a lot of nutrients and soil organic matter. This research is aimed to determine the effect of the kinds of organic fertilizers to Ca and Mg uptake and yield of groundnuts on degraded land. This research was done using Completely Randomized Design (CRD) single factor and three replications for each treatment. The results showed that organic fertilizer influence to Ca and Mg uptake and the yield of groundnut on degraded lands. Eichonia crasspies manure increased Ca and Mg uptake of groundnut on degraded soil. Cow manure fertilizer increased 200% of their groundnut production as compared to without organic fertilizer.

Mentik wangi is one of the local rice varieties in Indonesia less attractive to farmers. That is because the rice Mentik wangi has some weakness, namely a long harvest time, easy to collapse, and the results less than the maximum productivity. To increase the interest of farmers in rice cultivation Mentik wangi, then an attempt is made to improve the quality of rice Mentik wangi properties with plant breeding techniques one of which is a genetic mutation using gamma radiation. This study was conducted to determine the performance (performance) of rice Mentik wangi (M1) results of gamma-ray radiation that is expected to have a positive properties of new or better than its origin. This research was conducted in paddy fields in the village of Nangsri Lor, District Kebakkramat, Karanganyar and implemented in September 2015 to January 2016. Data were analyzed by descriptive with sorting and comparing each individual plant at each radiation dose to the average control accurately and objective. The results showed that gained some plants that could potentially be a mutant plant that has better properties (positive) that appears at the variable plants from each individual plant, ie the number of lines T16 with a radiation dose of 300 gray tall plants are very short 86 cm, strain number T204 with a radiation dose of 200 gray pick the highest panicle length of 33.5 cm, strain number T133 with a radiation dose of 100 gray has a total number of tillers and productive tiller high of 17 rods (total) and 11 rods (productive), strain number T133 with radiation dose of 200 gray had the highest number of filled grain and 624 grain strain T70 numbers with a radiation dose of 100 gray had the highest percentage of filled grain at 96%, and the number of lines T (1-7) with a radiation dose of 100 gray and strain number T ( 1-9) with a radiation dose of 200 gray had a shorter harvesting time is 110 days.

Land used in agriculture plays an important role in supporting the production of biomass. Destruction of land for biomass production is changing the nature of the soil that exceeded the standard criteria of soil damage. Mapping of land degradation status is useful to know the condition of the soil and tillage correct action. This study was conducted using a survey in the Subdistrict Cepogo Regency Boyolali. Existing data will be scoring and macthing with standard criteria for biomass production ground damage that Government Regulation No. 150 of 2000. Analysis of the data shows that there is no damage land area covering 744,1 Ha (13,7%) and there are areas relatively lightly damaged by parameters of degradation status, namely the composition of the fraction covering 494,4 ha (9,1%), the degree of release of water parameters covering 294,4 ha (5,4%) and a combination of parameters fraction composition and the degree of release of water covering 1.813 Ha (33, 4%).

Variation on orchid is an advantage that allows plant as breeding material. Orchid in plant breeding has a target to increase plant genetic diversity character who favored by the consumer. Efforts to increase genetic diversity among others by artificial mutation using gamma ray irradiation. This research aims to study the influence of gamma ray irradiation dose against the performance of morphology and growth of crossbred orchids ♀Vanda celebica x ♂Vanda dearei. Research using completely randomized design single factor that is dose gamma ray irradiation 0 Gray, 10 Gray, 20 Gray, 30 Gray, 40 Gray and 50 Gray. Data were analyzed descriptively, compared plant irradiation treatments with control plants to determine the effect of irradiation on morphology and growth plant. The results showed dose irradiation treatment increased the diversity of plant height, leaf amount, leaf length, leaf color changes, the amount and length of roots. 10 Gray dose irradiation increases as height and length plant leave. 30 Gray dose irradiation increase in the number of leaves. Leaf color change occurs at 20 irradiation treatments Gray and 50 Gray.

Vanda Orchid is one of the most popular ornamental plants. Orchids have slow growth. One way to overcome this weakness is by using gamma-ray irradiation. This research aimed to study the morphological characters of various radiation doses resulting from the crossing of the Vanda Orchid. This study was carried out by observing the characters of vegetative growth for each plant on 0 Gy, 10 Gy, 20 Gy, 30 Gy, 40 Gy, and 50 Gy doses of gamma irradiation treatments. The observed variables were the increase in plant height, leaf length, root length, number of roots, number of leaves, leaf width, and leaf color. The results showed that the dose of gamma-ray irradiation were able to increase plant height. 10 Gy and 20 Gy, gamma-ray irradiation doses, resulted in discolored yellowing of orchid leaves. The discoloration of orchid leaves to light green occurs at irradiation doses of 30 Gy, 40 Gy, and 50 Gy. The morphological characteristics of Vanda sp. hybrid results gamma irradiation are high at dose 10-40 Gy. Keywords: characteristics; morphological; orchid.
