Judul: Land Use Planning for Paddy Field Development in Pandeglang Regency
Abstrak: Food security is a big issue in Indonesia due to the availability of agricultural land caused by land conversion, especially in Java Island, is continually decreasing. Food security is the condition to meet food demand for the state to individuals, as reflected in the availability of sufficient food, both in quantity and quality, safe, diverse, nutritious, equitable, and affordable, and does not conflict with religion, belief, and culture of the community, to live a healthy life, active life, and productive in a sustainable manner. Therefore, the availability of agricultural land is one of the things that should be considered to ensure future food security, since agricultural land has a comprehensive function covering economic, social, and environmental aspects. However, the trend of agricultural land conversion in Java Island is very concerning. Several policies have been issued to tackle this problem, mainly LP2B (protected agricultural area) and the zoning regulation in spatial planning. However, further directives on these policies must also be formulated to give a further insight and some more comprehensive strategies on agricultural development. Pandeglang Regency is the largest rice production area in Banten Province, with the agricultural sector as the main economic activity in this region. Pandeglang Regency has potential in the agricultural sector, and agricultural land for food agricultural commodities, especially lowland rice, has the potential to be developed. Pandeglang Regency is also experiencing growth due to the enactment of Tanjung Lesung as a Special Economic Zone and various infrastructure development. However, the allocation and strategy for the agricultural area, especially rice/paddy fields, are still lacking and not detailed enough. Therefore, the analysis of the availability and needs of food land can be used to determine the minimum need for food land in Pandeglang Regency. This research aims to give directives on planning and development for the paddy field in Pandeglang Regency by giving an insight on its characteristics, availability, suitability, and potential in each region to be developed based on the spatial analysis result. The dynamics of land use change over the last 13 years in Pandeglang Regency are dominated by the increase of settlement areas, and the decrease of paddy field in contrast. The tradeoff between settlement and paddy field appears to be disproportional, where the rate of increase in settlement area is significantly bigger than the decrease of paddy field, meaning that the settlement area also converts other land uses as well. The other land uses experienced fluctuating change, such as plantation, shrubs, mix garden and bare land. Then this landuse trend are followed with CA-Markov prediction with business as usual (BAU) scenario. The prediction reached a good level of accuracy with kappa index of 0.89, with the end-year for land use prediction are set at 2031 following the year of spatial planning policy. Land use prediction using a CA-Markov method finds out that under BAU condition, settlement areas will continue to increase until the year 2031, with the rate of annual increase stays roughly the same. Meanwhile, the paddy field conversion in 2031 seems to have slowed down, following the 2012-2018 trend. It happened due to

Judul: The development directions of Agricultural Land for Paddy and  Banana commodities in Pidie Regency, Aceh Province
Abstrak: Struktur perekonomian Kabupaten Pidie di dominasi oleh sektor pertanian. Komoditas pertanian unggulan kabupaten ini diantaranya padi dan pisang. Meningkatnya jumlah penduduk dan perkembangan wilayah menyebabkan persaingan penggunaan lahan. Penelitian ini bertujuan mengidentifikasi jenis tutupan lahan tahun 2003, 2011, 2019 serta pola perubahannya, menganalisis ketersediaan lahan, dan menentukan arahan pengembangan lahan pertanian untuk komoditas padi dan pisang di Kabupaten Pidie. Metode yang digunakan dalam penelitian ini adalah menumpang-susunkan peta tutupan lahan, ketersediaan, dan kesesuaian lahan menggunakan software ArcGIS. Hasil penelitian: terdapat 11 jenis tutupan lahan. Perubahan tutupan lahan terluas pada tahun 2003 sampai 2011 yaitu pertanian lahan kering menjadi pemukiman, sedangkan tahun 2011 sampai 2019 yaitu sawah menjadi pemukiman. Lahan yang tersedia untuk pengembangan padi 3.246,09 ha, pisang 1.933 ha, padi dan pisang 903,82 ha, sedangkan lahan yang tidak tersedia 283.194,48 ha. Luas lahan yang diarahkan pengembangannya untuk komoditas padi dan pisang yaitu 5.869,76 ha dan 283.384,17 ha termasuk dalam lahan yang tidak direkomendasikan., Economical structure in Pidie Regency dominates of agricultural sector. The primary agricultural commodities of this region were paddy and banana. Improving in population and regional development leads to competition to land. This research aims to identify the land cover types in 2003, 2011, 2019 and their patterns of change, analyze land availability, and determine the development directions of agricultural land for paddy and banana commodities in Pidie Regency. The research method is the overlay maps of land cover, availability, and land suitability using ArcGIS software. The results: there were 11 types of land cover. The highest changes of land cover from 2003 to 2011 occurred in dry land farming into settlements, while for paddy field the highest changes in 2011 to 2019 into settlements. Land available aims to develop paddy 3.246,09 ha, banana 1.933 ha, paddy and banana 903,82 ha, while the land is not available 283.194,48 ha. The available land area for agriculture development including paddy and banana commodities 5.869,76 ha and 283.384,17 ha included for not recommended land area.

Judul: Isolasi komponen hemotoksin bisa ular kobra (Naja naja sputatrix)
Abstrak: Elisa ular adalah racun yang diproduksi oleh kelenjar bisa dan digunakan ular untuk mempertahankan dinat mencari mangsa. Bisa ini merupakan campuran dari berbagai komponen. Enzim adalah kompoth utama selain air. Enzim pada bisa ular sangat beragam jenis dan fungsinya. Fosfolipase dan arginin ipadase adalah enzim yang sering terdapat dalam bisa ular dan telah digunakan pada penanganan penyak seperti trombosis Penttian ini bertujuan mengisolasi komponen dari bisa ular kobra dan mengujinya menggunakan sel darah merah sapi 4% untuk aktivitas hemolisis dan bekuan fibrin sapi untuk aktivitas fibrinolisis. Uji aktivitas dilakukan terhadap ekstrak kasar dan fraksi kolom bisa ular. Fraksi kolom diperoleh dari pemurutan ekstrak kasar menggunakan kromatografi filtrasi gel (Sephadex G-75) untuk memperoleh fraksa paksu dengan serapan tertinggi pada A. 280 nm. Ekstrak kasar dan fraksi kolom dengan serapan tertinggi dilakukan pengukuran kandungan protein, Fraksi aktif hasil uji aktivitas selanjutnya ditentukan berat molekulnya (BM) dengan elektroforesis SDS PAGE. Basaglar kobra merupakan cairan pekat berwarna kuning dengan kadar air 71.45%. Dari hasil uji aktivitas diperoleh bisa ular hanya memiliki aktivitas hemolisis sel darah merah sapi secara langsung. Aktivitas ini ditunjukkan oleh fraksi kolom nomor 15 dan 16 tetapi tidak dalam ekstrak kasar. Penurunan konsentrasi ekstrak kasar tidak mempengaruhi terhadap adanya aktivitas hemolisis. Hal ini diduga karena mungkin terdapat inhibitor dalam ekstrak kasar bisa. Inhibitor memiliki BM yang berbeda dengan enzim hemalisis sehingga dapat dipisahkan menggunakan filtrasi gel. Berdasarkan hasil elektroforesis diperolch enzim bemolisis terdapat dalam ekstrak kasar dan tersebar pada fraksi kolom nomor 15 dan 16 dengan BM sekitar 27300 Da
