Judul: WebGIS Application for Monitoring Land Use Change
Abstrak: Indonesia is home to the world’s third largest tropical forest, it’s unfortunate that forest in Indonesia has been reported as the highest deforestation. Agriculture and plantation activities considered as one of factors that cause deforestation. This research focus on monitoring of 5 Commodities (cacao, coffee, oil palm, rubber and paddy) as a factor that causes forest loss in Indonesia. Remote sensing (RS) and geographic information system (GIS) is state of the art tools widely used for the monitoring land use change. Development of WebGIS on this research designed to be user friendly, up to date and can be easily integrated with other GIS system. The government, stakeholders and public users can monitor deforestation that caused by agriculture activities each of region in Indonesia quickly, furthermore help policy makers in provide more appropriate regulations on land use management. From the secondary data that has been analyzed, the result show that Indonesia has forest lost 12.3 million hectares from 2000 to 2018, of which an estimated 4.1 million hectares become plantations and agricultural areas. This means, about 33.5% of those 5 commodities activities have an impact on forest loss, and the remaining around 8.2 million hectares caused by other factors., Indonesia merupakan hutan tropis terbesar ketiga di dunia, namun sangat disayangkan hutan di Indonesia telah mengalami deforestasi tertinggi kedua di dunia. Kegiatan pertanian dan perkebunan dianggap sebagai salah satu faktor penyebab deforestasi. Penelitian ini fokus pada pengembangan WebGIS untuk pemantauan 5 komoditas (kakao, kopi, kelapa sawit, karet, dan padi) sebagai faktor yang menyebabkan hilangnya hutan di Indonesia. Remote sensing (RS) dan sistem informasi geografis (SIG) adalah teknologi yang banyak digunakan untuk memantau perubahan penggunaan tutupan lahan. Webgis pada penelitian ini dirancang ramah pengguna, datanya termuthakir dan dapat dengan mudah diintegrasikan dengan layanan map service dari sumber lain. Pemerintah, pemangku kepentingan, dan pengguna umum diharapkan dapat memantau deforestasi yang disebabkan oleh kegiatan pertanian di setiap wilayah di Indonesia dengan mudah dan cepat, lebih jauh lagi membantu penentu kebijakan dalam membuat peraturan yang lebih tepat tentang pengelolaan hutan. Dari data sekunder yang telah dianalisis, hasilnya menunjukkan bahwa Indonesia telah kehilangan hutan sekitar 12.3 juta hektar sejak tahun 2000 hingga 2018, di mana sekitar 4.1 juta hektar menjadi perkebunan dan area pertanian. Hal ini menunjukkan bahwa sekitar 33.5% dari 5 aktivitas komoditas tersebut berdampak pada hilangnya hutan, dan sisanya sekitar 8.2 juta hektar disebabkan oleh faktor lain.

Judul: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
