Pengaruh Pemberian Beberapa Jenis Pupuk terhadap Pertumbuhan dan Produksi Tanaman Kailan (Brassica Alboglabra L.)

Kailan included in a group of vegetables that have high economic value. Kailan low production occurred due to good soil physical, chemical and biological of soil due to the loss of nutrients in the soil. The addition of nutrients in the soil to increase crop production kailan can be done by way of fertilization. Fertilization can be done with use of organic fertilizers and inorganic fertilizers. The aims of this research are to determine the effect of some types fertilizer on the growth and yield of kailan and to obtain the best dose of treatment. This research was conducted experimentally by using completely randomized design (CRD) factorial with consisted of 5 treatments and 3remedial. The result of research show suggest that administering some kind of fertilizer for crops kailan significant on plant height, plant fresh weight, weight of plants suitable for consumption and the ratio of the root crown , but not significant on the number of leaves. NPK fertilizer with a dose of 0.025 kg/m2 is the best treatment to improve growth and crop production kailan.

Pembuatan Permen Jelly Ektrak Jahe Merah dengan Penambahan Karagenan

The purpose of this research is to get the precise formulation of the red ginger extract and carrageenan thus producing jellycandies with good quality and appropriate quality standard based on SNI 3574-2-2008 jelly candies. This study was conducted experimentally using a completely randomized design (CRD) with five treatments and three replications. The treatment in this study was JK1 = red ginger extract + carrageenan (41.50 + 7.50), JK2 = red ginger extract + carrageenan (40.50 + 8.50), JK3 = red ginger extract + carrageenan (39.50 + 9.50), JK4 = red ginger extract + carrageenan (38.50 + 10.50), and JK5 = red ginger extract + carrageenan (37.50 + 11.50). Data were analyzed using analysis of variance and in a further test using DNMRT at 5% level. The treatment provides significant effect on moisture content, ash content, acidity (pH), reducing sugar, antioxidant and colour, aroma, taste descriptively. The best treatment in this study was JK1 = red ginger extract + carrageenan (41.50 + 7.50), with a water content of 12.84%, ash content of 0.85%, the degree of acidity (pH) 6.47, reducing sugar 19.74% and antioxidant 2.77 µg/ml as well as having the characteristics of 3.13 (slightly yellow-brown colour), 2.10 (ginger-flavored red), 2.23 (spicy flavor) and 3.20 (slightly chewy texture) and an overall assessment of jelly candy ginger extract and preferably carrageenan by panelist's.

Pemanfaatan Susu Full Cream dan Minyak Sawit Merah dalam Pembuatan Es Krim Ubi Jalar Ungu (Ipomoea Batatas L.)

The purpose of this research was to obtain the formulation of full cream milk and red palm oil in the making of ice cream with the best of value fat content, protein content, overrun, melting point, total solids, and organoleptic test. This research used a Completely Randomized Design (CRD) with four treatments and four replications. The treatments were K1 (Full cream milk : red palm oil = 100% : 0%), K2 (Full cream milk : red palm oil = 97% : 3%), K3 (Full cream milk : red palm oil = 94% : 6%),K4 (Full cream milk : red palm oil = 91% : 9%). The data obtained were analysed statistically by using Analysis of Variance (ANOVA). If the F count was greater than or equal to F table then continued with DNMRT test at 5% levels. The results of this research showed that the formulation of full cream milk and red palm oil in the making of ice cream indicated significant effect (P<0,05) on fat content, protein content, overrun, melting point, total solids, and organoleptic test. The treatment K3 having overrun 19.59%, melting point 12.20 minutes, fat content 17.91%, protein content 2.86%, total solids 28.99%. The ice cream obtained from K3 was also preferred by panelists than other treatments especially for colour and flavour of description test and taste, flavour, and acceptance test of hedonic.
