Quality tempeh has the characteristics of being compact, slightly grayish-white in color, and has a distinctive tempeh aroma. In general, tempe is packaged using banana leaves and plastic. The type of packaging in temphe can affect the quality characteristics of tempe. The purpose of this study was to analyze the quality characteristics of tempe with packaging using klobot (corn husk) on four main parameters are protein content, moisture content, shelf life, and organoleptic properties. This study used a completely randomized design with three treatments and three repetitions, namely banana leaf packaging, plastic packaging, and klobot packaging. Based on the results obtained, the use of the type of packaging has a significant effect on the 95% significance level on the physicochemical characteristics (protein and moisture content). Tempeh wrapped in klobot has a protein content of 23,87 ± 1,17 (%) and a moisture content of 51,58 ± 0,30 (%). This value is in accordance with Indonesian National Standard 3144: 2015 that the protein content of soybean tempeh is at least 15% (w/w) and the moisture content of soybean tempeh is a maximum of 65%. Next, the shelf-life analysis showed that tempeh wrapped in klobot had a shelf life of 5 days with a slight tempeh texture. Then based on the result of the organoleptic test, variation of treatment has no significant effect at the 95% significance level on organoleptic characteristics of color, flavor, texture, taste and significantly affects overall preference organoleptic characteristics. \u0000Keywords: Klobot, packaging, quality characteristics, tempeh \u0000  \u0000ABSTRAK \u0000Tempe merupakan makanan olahan yang dibuat dari kacang kedelai hasil fermentasi menggunakan kapang Rhizopus oryzae atau Rhizopus oligosporus yang memiliki kandungan gizi utama yaitu protein sebesar 56%.

Some functions of these ingredients’ addition include a preservative, flavoring, coloring, antioxidant, and others. Tempeh is one of the foods consumed by many people, especially in Indonesia. The addition of additives to tempe can increase its nutritional components such as increasing antioxidant levels. Butterfly pea flower (Clitoria ternatea L.) is added as an additive to increase antioxidants because, from several studies, the flower has a high antioxidant. The addition of butterfly pea flower is also expected to affect the antioxidant activity and give the tempe an attractive aroma, taste, and color. The objective of this research was to determine the effect of butterfly pea flower addition with concentrations of 0%, 0.5%, 1%, 1.5%, and 2% on antioxidant activity using the DPPH method, and the organoleptic properties of tempeh based on the preference level (hedonic) using a questionnaire. Based on the results obtained, it was shown that the addition of butterfly pea flower was able to increase the antioxidant activity. This can be seen from the IC50 value at the addition at 2% concentration, which showed the highest value of 2398.5 ppm from each treatment even though in the antioxidant power category, it was still relatively low. Then on the organoleptic test, the results showed that in the color parameter, panelists tended to like the butterfly pea flower addition at a concentration of 1%, while in the aroma and taste parameters the panelists liked the butterfly pea flower addition at a concentration of 0.5%.   \u0000Keywords: Antioxidant; butterfly pea flower (Clitoria ternatea L.); natural dye; organoleptic; tempeh. \u0000  \u0000ABSTRAK \u0000Bahan tambahan pangan atau bahan aditif merupakan bahan ataupun campuran yang jika ditambahkan ke dalam bahan baku dapat mempengaruhi sifat serta bentuk dari suatu makanan dan minuman.

It can be concluded that the addition of dates can increase the acceptance of the taste, aroma, viscosity, and color of almond extract yoghurt. \u0000Keywords: Almond extract; dates; yoghurt; acceptance \u0000  \u0000ABSTRAK \u0000Tujuan dari penelitian ini yaitu mengetahui penerimaan yoghurt sari almond dengan penambahan kurma. Penelitian ini terdiri atas tiga tahap. Tahap pertama meliputi persiapan bahan dan peralatan serta penyusunan formula yoghurt sari almond dengan penambahan kurma. Tahap kedua yaitu proses pembuatan yoghurt sari almond dengan penambahan kurma. Tahap ketiga yaitu pelaksanaan uji hedonik dan uji peringkat. Persentase penambahan kurma pada pembuatan yoghurt sari almond yaitu sebanyak 10%, 20%, dan 30% dari berat sari almond. Uji hedonik dan uji peringkat melibatkan 30 panelis tidak terlatih. Data dianalisis menggunakan analisis nonparametrik uji Kruskal Wallis dan uji lanjut Mann-Whitney. Hasil uji Kruskal Wallis menunjukkan penambahan kurma memberikan perbedaan yang nyata pada penerimaan rasa, aroma, kekentalan dan warna yoghurt sari almond. Uji lanjut Mann-Whitney menunjukkan bahwa rasa, aroma, kekentalan dan warna dari yoghurt sari almond dengan penambahan kurma sebanyak 10% berbeda nyata dengan 20% dan 30%. Dapat disimpulkan bahwa penambahan kurma dapat meningkatkan penerimaan rasa, aroma, kekentalan dan warna yoghurt sari almond. \u0000Kata kunci: Kurma; penerimaan; sari almond; yoghurt.","PeriodicalId":126879,"journal":{"name":"AGRITEKNO: Jurnal Teknologi Pertanian","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125769655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of red bean flour is needed to replace protein sources while waxy rice flour contributes to carbohydrate replacement. The purpose of this study was to know and to determine the characteristics of instant porridge with the ratio of red bean flour and waxy corn flour. Results showed that the characteristics of instant porridge were influenced by the different ratios between red bean and waxy corn flour on instant porridge ash, protein, fat, fiber, carbohydrate contents as well as ask bulk density and rehydration powder. The ratio between corn and red bean flours of 80% and 20% resulted in instant porridge with moisture, protein, and carbohydrate of 3.44%, 10.8%, and 80.53%, respectively and met the quality standard set by SNI 01-7111.4-2005, an ash content of 1%, a fat content of 0.76% the fiber content of 3.79%, bulk density of 1.03 g/mL, and rehydration power of 2.83 mL/g.: instant porridge, the ratio of red bean, and waxy flour. \u0000Keywords: instant porridge, the ratio of red bean and waxy cornflour \u0000  \u0000ABSTRAK \u0000Masyarakat lebih memilih makanan yang dikonsumsi secara praktis dalam bentuk penyajian maupun dalam pembuatannya tanpa mengurangi pemenuhan kebutuhan gizi. Penggunaan tepung kacang merah diperlukan sebagai sumber protein dan penggunaan tepung jagung pulut sebagai pengganti karbohidrat. Tujuan dari penelitian adalah untuk mengetahui dan menentukan karakteristik bubur instan dengan rasio tepung kacang merah dan tepung jagung pulut. Hasil penelitian menunjukan bahwa karakteristik bubur instan dipengaruhi oleh rasio tepung kacang merah dan tepung jagung pulut yang berbeda terhadap kadar air, kadar abu, kadar protein, kadar lemak, kadar serat, kadar karbohidrat, densitas kamba dan daya rehidrasi.
