Salah satu jenis rebung bambu yang tumbuh di Bali adalah rebung bambu tabah (Gigantochloa nigrociliata Buse-Kurz). Melihat kandungan air yang dimiliki rebung sangat tinggi, maka daya simpan dan daya guna rebung dapat ditingkatkan dengan membuatnya menjadi produk setengah jadi berupa tepung. Tepung rebung merupakan salah satu bahan makanan yang bersifat kering dan juga mudah mengalami perubahan komponen. Dalam mempertahankan mutu suatu bahan pangan, kemasan memiliki peranan yang sangat penting. Penelitian ini dilaksanakan untuk menentukan jenis kemasan yang tepat dalam mempertahankan karakteristik mutu tepung rebung. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari dua faktor, faktor pertama adalah jenis kemasan yaitu (K1) : polipropilen, (K2) : aluminium foil, dan (K3) : paper sack. Faktor kedua adalah lama penyimpanan yaitu (H1) : 10 hari, (H2) : 20 hari, (H3) : 30 hari. Parameter yang diamati adalah kadar air, daya serap air, densitas kamba, serat kasar, derajat putih, dan uji sensoris.

The use of concentration CaCl2 has many benefits, of which it is easy to apply and can prevent food collation from becoming soft as a result of the processing and heating effect. The research was carried out to determine the CaCl2 concentrations and the correct drying temperature of tabah bamboo shoots flour. The study used a completely randomized design (CRD) which consisted of two factors, the first factor used in the research design is a CaCl2 concentration of worms and the second factor used is drying temperature. The first factor consists of four levels, CaCl2 concentrations 0%, CaCl2 concentrations 2%, CaCl2 concentrations 4%, CaCl2 concentrations 6%. The second factor is three degrees, drying temperature 60?, 70?, and 80?. The parameter observed in the study consist of yield, water level, ash content, protein levels, rough fibers, colors, and organoleptic test consisting of the color, aroma, texture, and overall acceptance of the hedonic test. The best treatment combination is a CaCl2 6% and drying temperature 80°C, which result in water 10,70%, ashes level 24,23%, protein level 24,","PeriodicalId":400994,"journal":{"name":"Jurnal BETA (Biosistem dan Teknik Pertanian)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116198291","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}

This research was conducted to obtain the optimum combination of drying temperature and slice thickness and determine the mathematical model to predict water activity, moisture content, ash content, and Q value through Response Surface Methodology (RSM). The data were processed using the Design Expert ® 12 software. Based on the testing and analysis, the results generated linear and quadratic models on the observed responses. The linear model was generated on water and ash content, while the quadratic model was generated on water activity and Q values. The drying temperature was 65.867?C, and the slice thickness of 3 mm was the chosen optimum combination. The verification test results show that the actual value of water activity is 0.218 aw, water content is 9.974%, ash content is 3.316%, and Q value is 31.950 kJ/h. The desirability value of the combination of drying temperature and optimum slice thickness of 0.898 indicates that 89.8% of the expected response criteria can be achieved. ","PeriodicalId":400994,"journal":{"name":"Jurnal BETA (Biosistem dan Teknik Pertanian)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130421258","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}
