Judul: Recovery Strategy of Gillnet Fishery after the COVID-19 Pandemic in the Fish Landing Center of Karangsong, Indramayu
Abstrak: Dampak pandemi COVID-19 dirasakan pada segala aspek kehidupan, salah satunya pada sub sektor perikanan. Menurunnya permintaan selama pandemi COVID-19 mengakibatkan turunnya harga ikan dan produksi ikan. Hal tersebut berpengaruh terhadap aktivitas penangkapan ikan. Dampak pandemi juga dialami oleh PPI Karangsong Indramayu, sehingga dibutuhkan strategi untuk pemulihan agar meminimalisir dampak negatif pandemi COVID-19. Tujuan penelitian adalah mendeskripsikan gambaran umum terkini perikanan gillnet di PPI Karangsong Indramayu, mendeskripsikan kinerja perikanan gillnet sebelum dan selama pandemi, merumuskan strategi pemulihan perikanan gillnet ke depan di PPI Karangsong Indramayu. Metode pengumpulan sampel pada penelitian ini adalah accidental dan purposive sampling. Analisis data yang digunakan yaitu analisis deskriptif dan analisis SWOT. Hasil penelitian menunjukkan nelayan menggunakan kapal gillnet ukuran 1 150 GT, menggunakan jaring gillnet 17 160 piece ukuran mata jaring 3,8 5,5 inci, serat pilinan 8 21 ply. Produksi ikan selama pandemi mengalami penurunan sebesar 19,5% 22% dari tahun sebelumnya. Nilai produksi juga mengalami penurunan sebesar 34-36% dari tahun sebelumya. Strategi pemulihan yang perlu dilakukan di PPI Karangsong yaitu, optimalisasi teknologi penangkapan dan pelatihan SDM.

Judul: The Impact of Covid-19 Pandemic on Fish Marketing Activities at Palabuhanratu Fish Auction
Abstrak: Pandemi covid-19 menyebabkan terbatasnya kegiatan di tengah masyarakat dan hal tersebut diduga akan berdampak pada kegiatan pemasaran di Tempat Pelelangan Ikan (TPI) Palabuhanratu. Tujuan penelitian ini adalah mengidentifikasi dampak covid-19 terhadap aktivitas pemasaran ikan di TPI Palabuhanratu, membandingkan keuntungan pedagang ikan pada saat sebelum covid-19 dengan saat pandemi covid-19 dan merekomendasikan strategi untuk mengatasi dampak covid-19 terhadap aktivitas pemasaran ikan di TPI Palabuhanratu. Penelitian ini menggunakan metode studi kasus. Teknik pengambilan data untuk tujuan pertama dan kedua menggunakan metode accidental sampling serta tujuan ketiga menggunakan metode purposive sampling. Analisis data terdiri dari analisis deskriptif metode skoring, analisis keuntungan usaha, dan matriks SWOT. Hasil penelitian menunjukkan bahwa berdasarkan persepsi responden, terjadi beberapa perubahan aktivitas pemasaran ikan pada saat pandemi seperti menurunnya jumlah konsumen, harga jual ikan menurun, pendapatan pedagang menurun, serta menurunnya jumlah ikan yang dijual. Keuntungan pedagang mengalami penurunan hingga 50% yang berpengaruh terhadap biaya usaha dan total penerimaan para pedagang. Strategi dalam mengatasi dampak pandemi covid-19 terhadap aktivitas pemasaran ikan di TPI Palabuhanratu ialah penguatan sistem lelang, peningkatan fasilitas pendistribusian hasil tangkapan ke industri maupun pasar diluar daerah TPI, menyediakan layanan internet dan sosisalisasi digital marketing kepada para pedagang, menambah cold storage, dan melakukan sistem resi gudang ikan., Covid-19 pandemic caused limited activities in public and it is expected to have an impact on marketing activities at the Palabuhanratu Fish Auction (TPI). The purpose of this research are to identify the impact of covid-19 on fish marketing activities at TPI Palabuhanratu, compare the profits of fish traders in the time before covid-19 with during the covid-19 pandemic and recommend strategies to overcome the impact of covid-19 on fish marketing activities in TPI Palabuhanratu. This research use case study methods. Data collection techniques for the first and second purpose use accidental sampling methods as well as for the third-purpose using purposive sampling methods. Data analysis consists of descriptive analysis of scoring methods, profit analysis, and SWOT matrix. Result showed that based on respondents perception there were several changes in fish marketing activities during the pandemic such as declining consumer numbers, declining fish selling prices, declining merchant income, and decreasing the number of fish sold. Traders profits decreased by up to 50% which affects business costs and total acceptance of traders. Strategies in overcoming the impact of the covid-19 pandemic on fish marketing activities in TPI Palabuhanratu are strengthening the auction system, improving the distribution of catch facilities to industries and markets outside the TPI area, providing internet services and digital marketing socialization to traders, adding cold storage, and conducting fish warehouse receipt systems.

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.
