Abstract

Picung seeds {Pangium edule Reinw; contain 70% kernel (ireight) and 40% Imsk (weight). Itsnucleus seeds contain 21-27% oib that can be extracted. More than iia 70% cmqionait is oil cake. The hugeamount of oil cake can be used as a solid fuel sucb as biopellets. Picung biopelleis are produced by usinghydraulic press hi the form of solid pieces with a specific size. Picung oil cakes need to be unifDnidy distributedas a soUd piece. Therefore, it needs to be bound and unified as a solid piece. Bhiding problems can be solvedby adding tapkxs. Optunum addition of tapioca is not more than 5%. However, adding tapioca wiU reduce theburning caloric properties of the bio-pellets. To increaM the caloric properties, diesel-oil can be added,because diesel oil has high caloric value equal to 7020 kcaVkg. Thefinalstep of this research was to optimizethe composition of tapioca and bio-diesel blends to produce the bio-pellets which satisfies the IndonesianNational Standard (SNI) with the highest caloric value. The cntral composit des^ w » used ftr the experiment.Thefirstfactor (X,) was quantity of solar (ml) and the second factor (X,) was quantity of tapioai (gran^. Firstfactor's range were between 1 to 53 % (l/w) diesel oil over picung cake or 2,<i9-17,33 ml diesel oH. Thesecond factor range was I to 5 % (w/w) diesel oil over picung cake.

Abstract

Pandemi COVID-19 yang awalnya bermula di Wuhan Cina begitu cepat menyebar ke lebih dari 206 negara termasuk Indonesia. Penggunaan vaksin merupakan suatu tindakan preventif yang cukup efektif dalam pencegahan penularan COVID-19. COVID-19 disebabkan oleh SARS-CoV-2 yang merupakan hasil mutasi dari SARS-CoV yang memiliki sifat virulensi yang lebih tinggi dan menyebar lebih cepat. Terhitung pada tanggal 7 April 2020, jumlah orang yang terinfeksi telah mencapai lebih 1.352.045 orang di antaranya 76.328 orang meninggal dunia. Walaupun belum ada obat khusus untuk mengobati COVID-19, namun pemberian obat misalnya remdesivir, fapilavir dan chloroquin fosfat dapat menyembuhkan 293.665 orang pasien. Selain tindakan terapi, tindakan preventif seperti peningkatan kekebalan tubuh merupakan langkah yang penting untuk mencegah penularan berbagai jenis penyakit. Hasil penelitian menunjukkan bahwa probiotik dapat meningkatkan kekebalan tubuh melalui crosstalk antara probiotik dan mukosa usus. Interaksi antara probiotik dan mukosa usus dapat meningkatkan pembentukan limfosit yaitu sel B dan sel T, interleukin utamanya IL-10 dan IL-1β, imunoglobulin terutama IgA, sel NK dan sel Th-17. Pembentukan komponen ini secara langsung akan meningkatkan sistem kekebalan tubuh terhadap penularan berbagai penyakit termasuk COVID-19.
