Judul: The Correlation between Entrepreneur Characteristics and Water Apple Farming Performance in Demak District, Demak Regency
Abstrak: Kecamatan Demak merupakan salah satu sentra penghasil jambu air di Kabupaten Demak. Produktivitas jambu air di Kecamatan Demak mengalami fluktuasi selama beberapa tahun terakhir. Karakteristik wirausaha pada petani jambu air diduga menjadi salah satu faktor terjadinya flutuasi pada produktivitas jambu air di Kecamatan Demak. Tujuan penelitian ini adalah menganalisis hubungan karakteristik wirausaha dan kinerja usahatani jambu air di Kecamatan Demak. Penentuan sampel pada penelitian ini menggunakan teknik purposive sampling dan snowball sampling dengan jumlah 40 petani jambu air. Alat analisis yang digunakan dalam penelitian ini adalah Rank Spearman. Karakteristik wirausaha yang diteliti pada penelitian ini adalah percaya diri, inovatif, tanggung jawab, berani mengambil risiko, dan kerja keras. Pengukuran kinerja usahatani pada penelitian ini menggunakan indikator hasil produksi dan pendapatan. Hasil analisis menunjukkan bahwa kelima karakteristik wirausaha berkorelasi secara signifikan dengan kinerja usaha. Hal ini berati ketika karakteristik wirausaha petani jambu air meningkat maka kinerja usahatani akan meningkat.

Judul: The Relationship of Entrepreneurial Characteristics to the Performance of Rice Farmers in Pringkasap Village, Subang, West Java
Abstrak: Pertumbuhan wirausaha merupakan salah satu indikator penting dalam pertumbuhan ekonomi suatu negara. Wirausaha agribisnis harus memiliki karakteristik wirausaha untuk lebih meningkatkan kinerja usahanya. Paguyuban Bumi Mandiri merupakan kelompok tani yang aktif mengusahakan padi organik di Kabupaten Subang, namun masih sedikit yang menerapkan budidaya padi organik. Penelitian ini mencoba memperlihatkan hubungan karakteristik wirausaha petani padi di Desa Pringkasap terhadap kinerja usaha yang dihasilkan. Karakteristik wirausaha yang digunakan dalam penelitian ini adalah percaya diri, kerja keras, pengambil resiko, inovatif, mandiri, dan berorientasi masa depan. Kinerja usaha yang diukur meliputi hasil produksi dan keuntungan. Alat analisis yang digunakan dalam penelitian ini adalah korelasi Rank Spearman. Hasil analisis korelasi Rank Spearman menunjukkan terdapat perbedaan antara petani padi non organik dan petani padi organik. Hubungan karakteristik wirausaha terhadap kinerja usaha pada petani padi organik yang memiliki nilai positif dan signifikan meliputi percaya diri, pengambilan risiko, inovatif dan orientasi masa depan terhadap hasil produksi serta kerja keras dan inovatif terhadap keuntungan. Sedangkan pada petani non organik meliputi kerja keras, inovatif, dan mandiri terhadap hasil produksi serta mandiri dan orientasi masa depan terhadap keuntungan., Entrepreneurial growth is an important indicator of a country's economic growth. Agribusiness entrepreneurs must have entrepreneurial characteristics to further improve their business performance. Paguyuban Bumi Mandiri is a farmer group that is active in cultivating organic rice in Subang Regency, but only a few are implementing organic rice cultivation. This study tries to show the relationship between the entrepreneurial characteristics of rice farmers in Pringkasap Village to the resulting business performance. Entrepreneurial characteristics used in this study are self-confidence, hard work, risk-taking, innovative, independent, and future-oriented. Measured business performance includes production results and profits. The analytical tool used in this study is the Rank Spearman correlation. The results of the Spearman Rank correlation analysis showed that there were differences between conventional rice farmers and organic rice farmers. The relationship between entrepreneurial characteristics and business performance of organic rice farmers which has positive and significant values includes selfconfidence, risk-taking, innovation and future orientation towards production results as well as hard work and innovation towards profits. Whereas anorganic farmers include hard work, innovation, and independence for production and independence and future orientation towards profits.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
