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.

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.

Pola tanam merupakan suatu kegiatan usaha pertanian untuk memperoleh hasil yang maksimal dengan mempertimbangkan kondisi iklim dan tanah. Mengatur pola tanam adalah bagian dari perencanaan kegiatan pertanian untuk memperkecil resiko kegagalan panen. Perencanaan dan kesesuaian pola tanam sangat bergantung pada besar kecilnya intensitas curah hujan pada wilayah tertentu. Penelitian ini bertujuan untuk menentukan pola tanam tanaman pangan komoditas tanaman pangan berdasarkan neraca kesimbangan air di Kecamatan Umbu Ratu Nggay Barat Kabupaten Sumba Tengah. Penelitian ini dilakukan di Kecamatan Umbu Ratu Nggay Barat dengan metode pengumpulan data primer dan sekunder, dan selanjutnya dilakukan analisis laboratorium. Data-data yang digunakan adalah tektur tanah, suhu tanah, suhu udara, kemampuan tanah mengikat air dan data curah hujan bulanan sepuluh tahun terakhir. Untuk menghitung neraca keseimbangan air digunakan model jNSM (Java Newhall Simulation Model), dilanjutkan dengan software sistem informasi geografis untuk memetakan wilayah yang berada pada periode surplus air tanah maupun wilayah yang defisit air tanah untuk dapat menentukan alternatif pola tanam. Berdasarkan perhitungan neraca keseimbangan air, maka diperoleh alternatif pola tanam untuk kecamatan Umbu Ratu Nggay Barat dengan rata-rata ketersediaan air yang cukup (surplus) pada wilayah yang berbeda dengan pilihan tanaman yaitu Wilayah pertama dengan pilihan tanaman ubi jalar-bera; padi-bera atau jagung-bera dengan luas 588,83 ha (2,09%). Wilayah kedua dengan pilihan tanaman alternatif yaitu ubi jalar-bera; padi-kacang hijau-bera; jagung-kacang hijau-bera dengan luas 7.856,96 ha (27,95%). Wilayah ketiga dengan alternatif tanaman pilihan yaitu ubi jalar-bera; padi-padi-bera; padi-jagung-bera; padi-kacang hijau-bera; jagung-jagung-bera; jagung-kacang hijau-bera dengan luas 19.662,96 ha (69,96 %).
