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.

Abstract

Velva merupakan salah satu jenis makanan pencci mulut (frozen dessert) yang umumnya terbuat dari campuran pure buah, gula, dan bahan penstabil yang dibekukan sehingga memiliki tekstur halus dan menyerupai es krim. Buah pepaya memiliki aroma yang khas, sehingga jika diolah menjadi produk olahan velva akan menghasilkan aroma yang kurang disukai. Aroma velva pepaya dapat diperbaiki dengan mengombinasikan buah lainnya seperti pisang ambon.  Pisang ambon memiliki aroma yang khas, karena daging pisang ambon mengandung komponen-komponen volatil yang dapat menimbulkan aroma khas dari pisang ambon. Tujuan penelitian ini adalah untuk memperoleh rasio terbaik dari bubur pepaya dan bubur pisang ambon terhadap karakteristik kimia dan sensori velva. Penelitian ini dilakukan secara eksperimen dengan menggunakan rancangan acak lengkap (RAL) dengan lima perlakuan dan tiga kali ulangan sehingga diperoleh 15 unit percobaan.  Perlakuan velva dalam penelitian ini yaitu perbandingan bubur buah pepaya dan pisang ambon meliputi PP1 (70:30), PP2 (60:40), PP3 (50:50), PP4  (40:60), PP5 (30:70).  Data yang diperoleh dianalisis secara statistik dengan menggunakan ANOVA. Jika F hitung lebih besar atau sama dengan F tabel maka analisis akan dilanjutkan dengan uji lanjut duncan multiple range test (DMRT) pada taraf 5%.

Abstract

Kombucha tea is a fermented beverage characterized by a sour taste with a slight sweetness. The basic ingredients of kombucha tea can be made using gambir leaf tea because it has high antioxidants. Gambir leaf tea has a bitter and astringent taste, therefore efforts are needed to reduce this by fermenting it and adding honey as a source of sugar. This study aims to determine the appropriate concentration of honey in making kombucha tea from gambir leaves. The study was conducted experimentally using a completely randomized plan (CRD) with 4 treatments and 4 replications. The treatment in this study was the addition of honey concentration (7.5, 10, 12.5 and 15%). The parameters observed in this study were total acetic acid, acidity level (pH), total dissolved solids, antioxidant activity and sensory assessment. Data obtained from the observations were statistically analyzed using analysis of variance (ANOVA) on IBM SPSS software version 25 and continued with Duncan's multiple range test (DMRT) at the 5% level.

Abstract

The COVID-19 pandemic, which initially began in Wuhan, China, quickly spread to more than 206 countries, including Indonesia. The use of vaccines is a preventive measure that is quite effective in preventing transmission of COVID-19. COVID-19 is caused by SARS CoV-2 which is the result of mutations from SARS-CoV which have higher virulence properties and spread faster. As of April 7, 2020, the number of infected people has reached more than 1,350,045 people including 76,328 people have died. Although there is no specific drug to treat COVID-19, administration of drugs such as remdesivir, fapilavir and chloroquin phosphate could cure 293,665 patients. In addition to therapeutic measures, preventive measures such as increased immunity are important steps to prevent transmission of various types of diseases. The results showed that probiotics could increase immunity through crosstalk between probiotics and intestinal mucosa. Interaction between probiotics and intestinal mucosa could increase the formation of lymphocytes (B and T cells), interleukin mainly IL-10 and IL-1β, immunoglobulins especially IgA, NK and Th-17 cells. The formation of this component will directly increase the body’s immune system against transmission of various diseases including COVID-19

Abstract

Frozen combination of fruit puree, sugar, and stabilizers is commonly used to produce velva, a frozen food product with a smooth texture similar to ice cream. Papaya fruit has a distinctive aroma, so if it is processed into processed velva products it will produce an aroma that is less favorable. The aroma of velva papaya can be improved by combining other fruits such as ambon banana which has a distinctive aroma. This research aimed to obtain the best ratio of papaya puree and ambon banana puree based on the quality characteristics of velva. This research used a completely randomized design (CRD) to produce 15 experimental units, with five treatments and three replications. The treatment in this study was PP1 (70:30), PP2 (60:40), PP3 (50:50), PP4 (40:60), and PP5 (30:70). Parameters observed include total solids, overrun, melting time, crude fiber content, vitamin C, and sensory evaluation. The variance results showed that overrun, melting time, crude fiber content, total solids, and sensory evaluation were significantly influenced by variations in the amount of papaya puree and ambon banana puree. Based on analysis parameters, the selected treatment was a ratio of papaya puree and ambon banana puree PP3 (50:50), producing a total solids of 27.75%, an overrun of 7.69%, a melting time of 14.15 minutes. The crude fiber content of 2.40%. vitamin C 23,47 mg. Orange in color, banana flavor, and soft and hedonically liked by the panelists.
