Judul: Analisis Pendapatan dan Efisiensi Usahatani Mangga Sebelum dan Selama Pandemi Covid-19 di Desa Kerep, Kabupaten Rembang
Abstrak: Musim panen mangga tahun 2020 yang bertepatan dengan adanya pandemi covid-19 menyebabkan petani mangga di Desa Kerep menghadapi kendala penurunan produksi dan harga jual mangga yang berpengaruh terhadap turunnya penerimaan petani. Penelitian ini bertujuan untuk menganalisis pendapatan, efisiensi usahatani, dan perbedaan pendapatan petani mangga di Desa Kerep sebelum dan selama pandemi covid-19. Penelitian ini menggunakan data primer dari 44 responden petani mangga di Desa Kerep. Usahatani mangga dianalisis menggunakan analisis pendapatan, R/C, dan uji beda pendapatan menggunakan uji Wilcoxon. Pengolahan data menggunakan software Microsoft Excel dan SPSS versi 26. Hasil analisis pendapatan dan R/C menunjukkan bahwa pendapatan dan R/C atas biaya tunai dan biaya total usahatani mangga sebelum pandemi covid-19 lebih besar daripada selama pandemi covid-19. Hasil uji beda menunjukkan bahwa terdapat perbedaan yang signifikan antara produktivitas, penerimaan, pendapatan, dan R/C atas biaya tunai dan biaya total usahatani mangga sebelum dan selama pandemi covid-19. Sedangkan biaya tunai dan biaya total usahatani mangga sebelum dan selama pandemi covid-19 tidak menunjukkan perbedaan yang signifikan. Berdasarkan hasil analisis usahatani dan uji beda dapat diketahui bahwa pandemi covid-19 berpengaruh terhadap pendapatan petani mangga di Desa Kerep.

Judul: Analysis of Catfish Farming Income Before and During the COVID-19 Pandemic,(Study Case in Catfish Farmer in Bekasi Regency West Java)
Abstrak: Tujuan penelitian ini sebagai berikut untuk mengetahui dampak dari COVID- 19 terhadap budidaya lele sehingga dapat diindikasikan akibat pandemi adanya perubahan harga input , output dan jumlah permintaan. Penulis melakukan studi kasus secara kolektif terhadap lima pokdakkan yang ada di Kabupaten Bekasi, melakukan wawancara mendalam tentang bagaimana hasil pendapatan usahatani sebelum dan semasa pandemi COVID-19 apakah masih menguntungkan atau tidak. Hasil dari penelitian ini sebagai berikut struktur biaya dan penerimaan selama pandemi mengalami perubahan,sedangkan untuk selama pandemi petani lele tetap mendapatkan imbalan karena efisien, dan menguntungkan , dan dapat disimpulkan petani selama pandemi COVID-19 permintaan akan lele meningkat hanya saja petani tidak dapat menjangkau konsumen secara langsung harus melewati tengkulak. Hasil output budidaya hanya di beli tengkulak karena mentahan, seharusnya petani dapat mengolahnya sehingga dapat sampai ke tangan konsumen secara langsung tanpa melalui tengkulak. Sehingga disarankan untuk petani kabupaten Bekasi dapat mendiversifikasikan usahataninya misalnya menjadi lele kuning frozen sehingga dapat dipasarkan secara online., The purpose of this study is as follows to determine the impact of COVID-19 on catfish cultivation so that it can be indicated that due to the pandemic changes in input, output prices,and number of demand. Writers conducted a collective case study of five pokdakkan in Bekasi Regency, conducted in-depth interviews about how the results of farming income before and during the COVID-19 pandemic were still profitable or not. The results of this study are as follows: the structure of costs and revenues during the pandemic has changed, while during the pandemic catfish farmers still get rewards because they are efficient, and profitable, and it can be concluded that during the COVID-19 pandemic the demand for catfish increases only that farmers cannot reach consumers. must go directly to middlemen. The output of cultivation is only bought by middlemen because it is raw, farmers should be able to process it so that it can reach consumers directly without going through middlemen. So it is recommended for Bekasi district farmers to diversify their farming, for example into frozen yellow catfish so that they can be marketed online

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.
