Modified Atmosphere Storage of Mango with Ca(OH)2 as absorbent has been carried out in order to study the physiological and biochemical responses of mango during storage of 1, 2 and 3 weeks. Completely Randomyzed Block Design with Least Significant Different at five percents significant level were applied to combined of types of packaging and chemical absorbent as followed: Unpacked; Plastic of polyethylene (PE) with paper board;PE + Ca(OH)2 (300g/L) with paper board; Plastic of polypropylene (PP) with paper board and PP + Ca(OH)2 (300g/L) with paper board. Data were analysed with ANOVA and continued with LSD at five percents significant level. Respiration rate and ethylene productions, percentage of decay and weight loss, activity of ACC oxidase were determined at 1,2 and 3 weeks storage. The production of ethylene and the rate of respiration of mangoes were very low as compared to unpacked mangoes. The result also indicate that decays percentage and weight loss of mangoes that stored at modified atmosphere are lower than that unpacked mangoes. Modification of Atmosphere storage inhibited the physical properties, the activity of ACC oxidase, therefore paralelled the rate of respiration and ethylene productions leads to extention the storage life of mango up to three weeks. Keywords: mango, modified atmosphere, ACC oxidase, ethylene ABSTRAK Penelitian tentang “Penyimpanan Mangga secara Modifikasi Atmosfir Dengan Penggunaan Ca(OH)2 sebagai Absorbent ’ bertujuan untuk mempelajari respon fisiologis dan biokimia buah mangga selama penyimpanan 1, 2 dan 3 minggu. Rancangan percobaan yang dilakukan adalah Rancangan Acak Kelompok (RAK) dengan kombinasi jenis kemasan (PE= plastik polietilen dan PP= polipropilen,) dan Ca(OH)2 sebagai absorbent seperti berikut: Ko= Tanpa Kemasan; PE= Plastik PE dengan karton; PE+Ca(OH)2 =Polietilen + Ca(OH)2 (300g/L); PP = Polipropilen dengan karton; PP+ Ca(OH)2 (300g/L). Analisa data dilakukan dengan Analisis Keragaman dengan taraf nyata 5 % yang dilanjutkan dengan Uji Beda Nyata Terkecil pada taraf nyata yang sama. Analisa yang dilakukan terhadap Tingkat Respirasi dan Produksi Etilen, Tingkat Kerusakan, Susut Berat, Aktivitas Enzim ACC oksidase selama penyimpanan 1, 2 dan 3 minggu. Tingkat respirasi dan Produksi Etilen pada buah mangga yang disimpan secara atmosfir termodifikasi jauh lebih rendah daripada tingkat respirasi dan produksi etilen pada buah mangga yang disimpan tanpa kemasan. Buah mangga yang disimpan secara modifikasi atmosfir lebih rendah persentase kerusakan dan susut beratnya daripada tanpa kemasan, Aktivitas enzim ACC oksidase pada buah mangga yang disimpan secara modifikasi atmosfir separuh aktivitasnya daripada aktivitas enzim pada buah tanpa kemasan sehingga dapat memperpanjang masa simpan buah mangga sampai minggu ketiga.

The experiment was conducted in laboratory and arranged with Completely Randomized Design of single factor of the sweet potato and rice bran ratio ( f0 = 100% wheat flour, f1= 85% sweet potatote : 5% rice bran , f2 = 80% sweet potatote:10% rice bran, f3 =75% sweet potatote:15% rice bran, f4 =70% sweet potatote :20% rice bran, and f5=65% sweet potatote:25% rice bran. The parameter included moisture, ash and fat content, colour and bread loaf volume, flavor, aroma, colors and texture (hedonic and scoring). Data was analysed with analyses of variance and post hoc test with Duncan’s Multiple Range Test (DMRT) at five percent of level of significancy. The result showed that the ratio of sweet potato and red rice bran in composite flour affected on the moisture, ash, and fat content, colour, loaf volume, , flavor, aroma, and texture of the steamed buns. The ratio of 85% sweet potato and 5% rice bran in composite flour produced the best quality of the steamed buns. The steamed buns had moisture, ash and fat content of 38.62%; 1.24% and 4.25% respectively and the L value, Hue and loaf volume were 61.42; 64.67 and 7.79% . In term of taste, the buns was slightly like and sweet by the panelist. On the other hand, the flavor of the buns had rice bran flavor, the colour was slightly purple and texture was softer compared to the buns with 100% wheat flour.

ABSTRACT Wheat flour is one type of flour that was often used for making various types of foods and dishes such as noodles, bread, biscuits, cakes, cookies, and porridge. Availability of wheat flour supplied from imports. The high demand for wheat flour because of the increasing needs of the food industry. Dependence on wheat flour can have a negative impact on the country's economy. One alternative wheat substitution is tubers such as black potatoes. The purpose of this study was to figure the best formulation in making cakes from wheat flour and black potato flour. The results showed that the more addition of black potato flour caused a decrease in moisture content, increase in ash content and protein levels and a decrease in the level of preference of panelists. Adding potato flour to 10% produces a cake that preferred by panelists. Keywords: cake, Coleus tuberosus, wheat substitution ABSTRAK Tepung terigu merupakan salah satu jenis tepung yang sering digunakan dalam membuat berbagai jenis makanan dan masakan seperti mie, roti, biskuit, cake, cookies, dan bubur. Ketersediaan tepung terigu disuplai dari impor. Tingginya permintaan tepung terigu karena kebutuhan industri makanan yang terus meningkat. Ketergantungan terhadap tepung terigu bisa berdampak buruk terhadap perekenomian negara. Salah satu alternatif pengganti terigu adalah tepung umbbi-umbian seperti kentang hitam. Tujuan penelitian ini adalah menentukan formulasi terbaik dalam pembuatan cake dari tepung terigu dan tepung kentang hitam. Hasil penelitian menunjukkan semakin banyak penambahan tepung kentang hitam menyebabkan penuruan kadar air, penngkatan kadar abu dan kadar protein serta penurunan tingkat kesukaan panelis.

Replication of using coconut oil for frying many times may have negative impact on health. This research was to investigate the effect of filtration with activated carbon and addition of tocoferol on chemical and organoleptic properties of used coconut oil. The experiments were conducted in laboratory and arrangeed with Completely Randomized Design with 4 replications. The treatments were :V1 = addition of tocoferol 10+1 mg in used coconut oil 150+1 g.V2 = addition of tocoferol 20+1 mg in used coconut oil 150+1 g.V3 = addition of tocoferol 30+1 mg in used coconut oil 150+1 g.V4 = addition of tocoferol 40+1 mg in used coconut oil 150+1 g.V5 = addition of tocoferol 50+1 mg in used coconut oil 150+1 g.There are 20 experiments unit totally. Data was analyzed with analysis of variancees at 5 percent significant level. Polynomial ortogonal test was applied at the same significant level if there were found significantly difference among treatments of moisture content, rendemen, peroxide value, free fatty acid and iodium value and Least Significant Difference test for parameter of color and odor (Yitnosumarto, 1991). The result showed that no significant differences found on addition of tocoferol the used coconut oil. The moisture, free fatty acid and peroxide value of the oil tend to increase and decrease when it filtered with activated carbon. However, the iodium value was vise versa. The addition of tocoferol was unable to improve the oil quality. The oil without filtration had browniesh yellow colour, and become dark yellow with filltration using activated carbon. The oil odor was very unpleasent without filtration and rather unpleasent with filtration. The addition of tocoferol was uneffective to enhance the oil quality, but a little improvement of oil odor was found if it compared to the used oil with or without filtration. The rendemen of the used oil filtration was around 75,81 percent.
