Judul: Analysis of the Impact of COVID-19 Pandemic on  the Supply Chain of Fish Resources in Indonesia
Abstrak: Pandemi COVID-19 saat ini dengan cepat menyebar ke seluruh dunia yang menyebabkan dampak sosial dan ekonomi yang luas. Beberapa dampak buruk dapat dirasakan oleh seluruh dunia dan Indonesia, salah satunya pada sektor perikanan. Penelitian ini bertujuan menganalisis dinamika rantai pasok sumber daya ikan dalam perspektif produksi, ekspor dan impor perikanan di Indonesia selama pandemi COVID-19. Data yang diambil adalah data produksi, ekspor, dan impor produk perikanan dari Kementerian Kelautan dan Perikanan Republik Indonesia dengan rentang waktu Januari 2018 - Juni 2021. Hasil yang didapatkan menunjukkan bahwa selama pandemi COVID-19 terjadi penurunan volume produksi perikanan yang tidak berbeda nyata. Sektor ekspor dan impor juga sempat mengalami penurunan volume di awal pandemi, namun kemudian volumenya kembali stabil dan terus meningkat, begitu pula untuk ekspor produk komoditas unggulan perikanan Indonesia yang volume dan nilainya juga meningkat selama pandemi. Secara keseluruhan, volume produksi terdampak negatif oleh pandemi, sedangkan volume ekspor dan impor terdampak positif oleh pandemi., The current COVID-19 pandemic is rapidly spreading across the globe and causing wide-ranging social and economic impacts. Some of the bad impacts can be felt by the whole world, including Indonesia in the fisheries sector. This study aims to analyze the dynamics of the supply chain of fish resources in the perspective of fishery production, export and import in Indonesia during the COVID-19 pandemic. The data taken is data on production, exports, and imports of fishery products from the Ministry of Maritime Affairs and Fisheries of the Republic of Indonesia from of January 2018 to June 2021. The results obtained indicate that during the COVID-19 pandemic there was a decrease in the volume of fishery production that was not too significant. The export and import sectors also experienced a decline in volume at the beginning of the pandemic. However, the volume stabilized and continued to increase, as well as exports of Indonesia's leading fishery commodities, whose volume and value also increased during the pandemic. Overall, production volume was negatively affected by the pandemic, while export and import volume was positively affected by the pandemic.

Judul: Covid-19 and Export Performance of the Agricultural Sector in Indonesia
Abstrak: Sektor pertanian merupakan sektor yang dapat dimanfaatkan untuk meningkatkan pembangunan ekonomi. Selama pandemi Covid-19, sektor pertanian menjadi salah satu sektor yang mampu tumbuh positif dengan kontribusi ekspor yang cukup tinggi. Penelitian ini bertujuan untuk menganalisis keterkaitan, pengganda output, pendapatan, dan tenaga kerja dari sektor pertanian, serta kinerja ekspor sektor pertanian pada masa pandemi Covid-19. Metode analisis yang digunakan adalah analisis input output dengan menggunakan Tabel Input Output Indonesia Tahun 2016, klasifikasi 185 sektor yang diagregasi menjadi 48 sektor. Hasil analisis menunjukkan bahwa komoditas sektor pertanian memiliki kemampuan yang lemah dalam meningkatkan sektor hulu dan hilirnya. Sektor pertanian yang memiliki pengganda output, pendapatan, dan tenaga kerja tertinggi didominasi oleh unggas dan hasil-hasilnya. Kinerja ekspor sektor pertanian berpengaruh terhadap peningkatan output, pendapatan, dan tenaga kerja paling besar pada sektor kelapa sawit, kelapa, serta unggas dan hasil-hasilnya. Hal ini disebabkan sektor tersebut mendapat dampak yang kecil akibat adanya Covid-19 dan permintaan impor dari luar negeri masih cukup tinggi., The agricultural sector is sector that can be used to increase economic development. During the Covid-19 pandemic, the agricultural sector became one of the sectors that were able to grow positively with a fairly high export contribution. This study aims to analyze the linkages, output multipliers, income, and labor from the agricultural sector, as well as the export performance of the agricultural sector during the Covid-19 pandemic. The analytical method used is input output analysis using the 2016 Indonesian Input Output Table, the classification of 185 sectors which are aggregated into 48 sectors. The results of the analysis show that agricultural sector commodities have a weak ability to improve their upstream and downstream sectors. The agricultural sector which has the highest multiplier of output, income, and labor, is dominated by poultry and their products. The export performance of the agricultural sector has the greatest effect on increasing output, income, and labor in the oil palm, coconut, poultry and their products. This is because the sector has had little impact due to Covid-19 and the demand for imports from abroad is still quite high.

Judul: Rancang Bangun Alat Ukur Kadar Larutan Glukosa Berbasis Film Barium Stronsium Titanat (BST)
Abstrak: Barium strontium titanate (BST) is a photodiode as a ferroelectric material that has been developed in many application such as sensor technology. The purpose of this study is to design a simple measurement tool of glucose with BST thin film as the sensor component and the signal conditioning. The measurement tool test was done by measuring blood glucose levels ranging from 20 to 180 mg/dL, which is the range of glucose levels for person who has lack glucose to the excess glucose. The test results showed that the measurement tool could detect each addition of glucose levels by 1 mg/dL which would reduce the value of the output voltage of 0.0022 V. In addition, the test results showed that the response of the circuit approach to linear, the correlation coefficient (R2) is 0.9155 and 0.8931. The test results also showed good hysteresis as showed by the relatively same graphic plots.
