Judul: Motivational Access dan Ketidaksetaraan Digital di Kalangan Petani (Kasus: Kecamatan Tenjolaya, Kabupaten Bogor, Jawa Barat)
Abstrak: Penggunaan Teknologi Informasi dan Komunikasi (TIK) di sektor pertanian belum sepenuhnya dirasakan oleh seluruh masyarakat Indonesia dan menyebabkan ketidaksetaraan digital pada petani. Tujuan penelitian ini adalah untuk menganalisis karakteristik individu dan motivasi digital pada petani, menganalisis kemampuan digital pada petani, menganalisis penggunaan media digital pada petani, menganalisis hubungan antara karakteristik individu dan digital terhadap kemampuan digital pada petani, dan menganalisis hubungan antara kemampuan digital terhadap tingkat penggunaan internet di kalangan petani. Analisis data dalam penelitian ini menggunakan uji korelasi Rank Spearman dan Chi-Square. Hasil penelitian menunjukkan karakteristik petani pada indikator usia, pendidikan, lama berusahatani, tingkat kosmopolit, dan tingkat kepemilikan media berhubungan dengan tingkat kemampuan digital sedangkan pada indikator luas lahan, status penguasaan lahan dan tingkat pendapatan tidak berhubungan. Motivational Access menunjukkan hubungan terhadap tingkat kemampuan petani di seluruh indikatornya dan kemampuan digital petani memiliki hubungan dengan penggunaan media., The use of Information and Communication Technology (ICT) in the agricultural sector has not been fully felt by all Indonesians and has led to digital inequality among farmers. The purpose of this study was to analyze individual and digital motivation of farmers, analyze digital skills of farmers, analyze the use of digital media on farmers, analyze the relationship between characteristics and access to digital motivation on digital skills of farmers, and analyze the relationship between digital skills and level of internet use. among farmers. Data analysis in this study used Spearman Rank correlation test and Chi-square. The results showed that the characteristics of farmers on indicators of age, education, length of farming, cosmopolitan level, and level of media ownership were related to the level of digital skills on indicators of land area, land ownership status and income levels were not related. Motivational access shows a relationship with the level of ability of farmers in all indicators and the ability of digital farmers to have a relationship with the use of media.

Judul: Motivasi dan Kepuasan Penggunaan Media Internet oleh Petani Perempuan Pedesaan (Studi Kasus: KWT Kania, Desa Tajur Halang, Kecamatan Cijeruk, Kabupaten Bogor).
Abstrak: Kemajuan teknologi dewasa saat ini telah membawa kepada dunia global termasuk bidang informasi. Menyatunya internet dalam penyampaian informasi pertanian seharusnya merubah pertanian yang berkembang secara tradisional menjadi pertanian yang berkebudayaan industri. Melihat aktivitas komunikasi dan penyebaran informasi pertanian pada petani laki-laki dan petani perempuan dapat mengungkap perbedaan respons petani laki-laki dan perempuan terhadap informasi pertanian yang mereka terima, termasuk perbedaan dalam motivasi dan kepuasan penggunaan media informasi. Penelitian ini bertujuan untuk menganalisis hubungan antara karakteristik dan motivasi dengan penggunaan media internet oleh petani perempuan dan bagaimana tingkat kepuasan penggunaan media internet yang dirasakan oleh petani perempuan. Penelitian ini menggunakan metode sensus kepada 30 petani perempuan responden di Desa Tajur Halang, Kecamatan Cijeruk, Kabupaten Bogor. Hasil penelitian menunjukkan terdapat beberapa hubungan antara motivasi dengan penggunaan media internet dan tingkat kepuasannya.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
