Paddy field is a natural resource and have an important role in maintaining the stability of the community's food (rice) production. Banyubiru District is one of the biggest contributors in supplying the rice needs of the people in Semarang Regency. So that the research aims to identify the extent and rate of change in the use of rice fields from 2008 to 2018 in Banyubiru District. The research approach used is based on geographic information systems in analyzing satellite images. The satellite imagery used is multi-resolution imagery such as Landsat 5 TM in 2008, Worldview-2 in 2013, and SPOT 6 in 2018. Image interpretation uses a pixel-based classification method with the maximum likelihood method and on-screen digitization found in ENVI 5.3 and ArcGis software. 10.8. The land use classification system used refers to following the Indonesian National Standard 7654: 201. The results of the study explained that there had been a change in the area of paddy land use in the Banyubiru District from 2008 to 2013 of 68 ha and from 2013 to 2018 of 65 ha. In addition, the rate of land use change from 2008 to 2018 was 14.78 ha / year, so this event can be categorized as a class of rapid land change rate.

Peanut (Arachys hypogaea L.) is one of the highly nutritious foods. Every 100 grams contains calories 583 kcal, protein 23 grams, cholesterol 0%, 23 grams carbohydrate, 8 grams fiber, 22 grams phytosterol, beta - phytosterol 6.5 grams. The ain of the research: (1) Agrotecnology adaptation test of organic fertilizer to increase productivity. (2) To determine ideals dose of organic and anorganic fertilizer (3) To analyze aflatoxsin stimulation, The location of the research was Jepara Regency has good land characteristic for peanuts growt, The result of the research, are: (1) The use of organic fertilizer compottion with 1000 kg.ha¹ and anorganic fertilizer with nitrogen 50 kg.ha¹, phosphate 60 kg.ha-1 and 100 kg kalium.ha-1 ( pattern C) produces the characteristic chemical, physical and biology the best land. (2) Other treatment (pattern A, B, D and E) gives the results of chemical, physical and biology of the diverse land. (3) Treatment C give performances of the highest value, of: (a) Weight of dry seed in 1000 seeds weighing 307.53 grams (an increase of 34.86% of control), (b) Dry seed weight of 2.30 tonnes per ha. ( c) full of pods containing 78.89% (increase. 8.20%% of control), (d) production performance in terms of economic aspects of quality, namely the yield, the loop product, the highest yield in treatment D, 82, 03% or an increase of 40.95% of the control loop on the product yield as much as 58.20%. The product of pods, the highest yield in treatment E (organic fertilizer 2,000 kg / ha) of 81.94% or an increase of 41.18% of production pod control treatment as big as 58.04%. (3) Content of aflatoxin is influenced by the varieties of plants (genetic) and environment, especially soil and climate both on land and in the process of post-harvest. In treatment C, the lower aflatoxin content were both of seed after harvest (<1 ppb) and after storage for 1 month (30 days). Treatment C is economically provide the highest profits. The results can not be used farmers, because the test is done once the new adaptation. Stability of production and nutrients in each treatment is not optimal. So still need further study to achieve production stability and nutrients in the soil with the same experimental design at least 3 (three) times the investment. In addition, it is necessary also varieties that are resistant to postharvest infection of Aspergillus, sp appropriate to reduce the negative effect of aflatoxin.

The objective of the research was 1).Agrotechnology adaptation test of some peanut varietes, there were Kancil, Jepara and Cidaun strain in use of organic fertilizers, 2). Aspergillus flavus test on research land site and 3).analyze farm production. The research location in Suwawal Timur village, Pakis Aji, Jepara in April to September 2011. Research using Randomized Block Design (RBD) with 9 treatments and 3 replications. The treatments were attempted: Treatment A = Cidaun strain + 1 ton organic fertilizer per ha, B = Cidaun strain + 1.5 ton organic fertilizer per ha, C = Cidaun strain+2 ton organic fertilizer per ha, D = Jepara variety + 1 ton organic fertilizer per ha, E = Jepara variety + 2 ton kg organic fertilizer per ha, F = Jepara variety +1 ton organic fertilizer per ha, G = Kancil variety+1ton organic fertilizer per ha,H = Jepara variety+1500 kg organic fertilizer per ha, I = Jepara variety + 2 ton organic fertilizer per ha. Parameters observed: ability to grow crops, the percentage of plant growth, flowering and harvest, plant height, number of pods, and the percentage of empty pods, plant and wet pods heavy per plot, dried plant and pod weight per plot,there are carried out at harvest, dry seed weight and Aspergillus flavus test. Observations on the plant environment, including: the level of pests and diseases, test N, P, K, organic matter, pH, soil CEC and elements observation. The results indicated that 1) Kancil variety with organic fertilizer 1.5 tons / ha had the highest peanut production because they had adaptif performance ie more resistant to leaf spot and withered base of stem diseases, number of pods 19.80 with weight 25.34 grams and 20.59% empty pods, dry seed weight of 23.14 grams per plant in 100 dry beans weighing 44.54 grams, the weight of dry beans as much as 2.10 tons per ha. 2) All soil treatment before and after the research conducted was containing Aspergillus sp that has a chance of aflatoxin contamination in peanut pods. 3) Economycally at the same fertilization treatment Kancil variety more favorable than Jepara variety and Cidaun strain. The dose of 1.5 tons per hectare fertilizer in Kancil variety gave the highest benefits (Rp. 28. 593 000, -.)compared with other treatments.

Lewa is one of districts in East Sumba Regency, Nusa Tenggara Timur (NTT) Province. It is characterized by dry land, its agriculture depends on rain. The main commodities are Oryza sativa and Zeamays. Due to lack of water, the cropping pattern design is vital. One of methods for designing crroping pattern is water balance analysis. The aim of this study was to understand water balance status and to decide the cropping pattern based of paddy and corn farming in Lewa District. The NRCS Java Newhall Simulation Model (jNSM) was adopted for water balance modeling. The water balance status then was mapped by using the Arc view software for showing total water availability in Lewa district. There were two zones: I (water availability 413 mm/year) and II (water availability: 868 mm/year). Based on the water availability, the zone I could be designed one period a year in rainy season (December-April) with cropping option paddy or corn. While zone II could be planted two times with cropping option corn-paddy or corn-corn.

The regency of Sumba Tengah in the province of East Nusa Tenggara relies on rainfall to support its dry land agriculture hence should be supported with land suitability evaluation and cropping pattern design for a more sustainable crop production. This study aims to evaluate land suitability for food crops in Sumba Tengah and formulate the appropriate precipitation-based cropping patterns. This work was carried out from March to June 2015. Stages of research were: 1) characterizing land attributes (climate and soil) by soil analysis and desk study, 2) assessing land suitability level by comparing land attributes and crops requirements, and 3) composing feasible cropping patterns by using water balance method. Soils of Sumba Tengah varied from sandy to clayey with low to neutral pH and low to very high content of organic carbon and nitrogen. Phosphate and potassium availability was very low. Sumba Tengah was exposed to only four wet months a year with annual precipitation of less than 2000 mm. This region was highly and moderately suitable for growing paddy, maize, tubers, and legumes. It was not suitable for wheat. Some of the northern part was arable merely for one cropping season in a year, mostly from December to April, with the alternative of growing paddy or other crops. The remaining was likely to cultivate for two cropping seasons. Legumes were recommended to include in the rotation for soil conservation. Shortage of irrigation led to the unlikeliness of three cropping seasons in a year.
