Judul: Formulasi Chocolate Filling dan Pengaruhnya terhadap Perubahan Mutu Roti Manis
Abstrak: Sweetbread filled with chocolate is the most popular but this bread’s crumb generally becomes hard (staling) faster. Lower water activity of filling than crumb could drive water movement from the crumb into the filling caused crumb become dry and hard. The purpose of this research are to study the effects of the type and the percentation of emulsifiers (SSL and GMS; 0.8%, 1.0%, 1.2%, 1.4%) and margarines (Blueband and Simas Palmia; 25.5%, 27.5%, 29.5%, 31.5%) to the characteristic of chocolate filling and study the chocolate filling effect on quality changes of sweetbread. The selected formulas from those formulations were applied in sweetbread and sensorically evaluated with hedonic’s rating test. Texture profile, water content, and water activity of sweetbreads filled with chocolate were analyzed for 5 days of storage in room temperature. The type and the percentation of emulsifiers had significant effects on the viscosity, water activity, and emulsion stability of chocolate filling (p<0.05). The selected formulas were 1.2% SSL and 1.2% GMS. The following step showed that the combination of margarine-emulsifier and margarine percentation had significant effects on the emulsion stability and viscosity of chocolate filling (p<0.05). The selected formulas that filled into sweetbread were BB SSL 25.5%, SP SSL 27.5%, BB GMS 29.5%, dan SP GMS 27.5%. Organoleptic test showed that panelist preference on the aroma, color, and texture attributes of sweetbreads filled with different chocolate filling formulas are not significantly different including with the commercial product (p>0.05). Chocolate filling formulas and storage’s time significantly affected the value of hardness, chewiness, and water content of the crumb also the water content and water activity of chocolate filling in the sweetbread (p<0,05). The lowest rate of crumb hardness during storage was the sweetbread filled with chocolate GB3 (GMS 1.2%: BB 29.5%).

Judul: Pengaruh Lama Waktu Penggorengan dan Presentase Coating Gula Terhadap Mutu Tekstur Coklat Tempe.
Abstrak: Tempeh chocolate is one of tempeh-based food product development. However, the product texture quality can easily changed when stored at room temperature. Combination of treatment by frying and sugar coating which are following kering tempe making process is expected to improve texture quality. This study is divided into two steps. The first step is preliminary study which consist of determining the magnitude of treatment that will be used. The second step is observation of tempeh chocolate texture quality which had been given both physical and organoleptic treatment and proximate analysis of selected sample. Selected sample is sample which can maintain texture quality of tempeh chocolate for the longest time and selected sample is sample with frying duration up to 10 minutes and 50% sugar coating. Based on statistical analysis using Duncan’s test, frying duration and sugar coating percentage as well as interaction between them give tangible effect to tempeh chocolate hardness at 5% significancy rate. Proximate analysis of selected sample shows that sample contains 1.47% moisture content, 0.96% ash content, 31.99% fat content, 17.34% protein content, and 48.26% carbohydrate content.

Abstrak: Ikan karang di Indonesia merupakan sumberdaya hayati yang patut untuk diperhatikan karena Indonesia merupakan negara kepulauan dengan iklim tropis, di mana 213 dari wilayahnya berupa laut . Ikan karang merupakan sekumpulan ikan yang berada di daerah tropis dan kehidupannya berkaitan erat dengan terumbu karang. Ikan-ikan tersebut memanfaatkan terumbu karang secara langsung maupun tidak langsung untuk kepentingan hidupnya. Masing-masing jenis ikan karang mempunyai peran yang berbeda dalam kaitannya sebagai bagian dari ekosistem terurnbu karang.
