ABSTRACT                     This study aimed to analyze the effect of lindur fruit flour substitution on organoleptic characteristics, nutritional value, and antioxidant activity of lindur fruit flour brownies. This research was conducted using a completely randomized design (CRD) with various percentages of formulation of substitution of lindur fruit flour:wheat flour, namely M1 = (100%:0%), M2 = (90%:10%), M3 = (80%:20 %), M4 = (70%:30%), and M5 = (60%:40%). The research data were analyzed using analysis of variance, with further testing using Duncan's Multiple Range Test (DMRT) at a 95% confidence level. The results show that the HCN content of lindur fruit flour reached 21.81 mg/kg. The M3 treatment was the most preferred treatment by the panelists with hedonic rating scores of color, texture, aroma, and taste reached 4.14 (like), 4.13 (like), 3.79 (like), and 4.30 (like), respectively. The nutritional values of selected M3 brownies show that it contained 30.57% water, 1.20% ash, 3.70% fat, 5.63% protein, and 58.90% carbohydrate. Analysis of antioxidant activity in selected M3 brownies was 465.58 ppm which is categorized as very weak. It can be concluded that the substitution of lindur fruit flour in making brownies had a very significant effect on color, texture, and taste. However, the effect was not significant on the aroma and the analysis of the nutritional value of the selected treatment. The brownie product substituted with lindur fruit flour met the national standards for water, ash, and fat contents.Keyword: Brownies, Lindur Fruit ABSTRAK    Penelitian ini bertujuan untuk mempelajari pengaruh substitusi tepung buah lindur terhadap karakteristik organoleptik, nilai gizi, dan aktivitas antioksidan brownies tepung buah lindur.

ABSTRAK. Penelitian efek penambahan bentonit dalam proses pelleting terhadap total bakteri dan total fungi dari produk pellet limbah penetasan sebagai bahan pakan alternatif, telah dilaksanakan di Laboratorium Teknologi Pakan, Fakultas Peternakan dan Pertanian, Universitas Diponegoro. Penambahan bentonit pada proses pelleting diharapkan mengurangi total bakteri dan total fungi pada pellet olahan limbah penetasan, sehingga aman digunakan sebagai bahan pakan alternatif. Pada penelitian ini limbah penetasan yang berupa cangkang telur, telur infertile, telur gagal menetas, serta DOC afkir dan mati dihancurkan, dicampur dengan bentonit dan dibuat pellet, untuk kemudian dianalisis kandungan total bakteri dan total fungi pada produk pellet. Perlakuan bentonit dilakukan dengan aras 0, 2, 4 dan 6% (B/B). Penelitian dilakukan dengan rancangan acak lengkap (RAL) 4 perlakuan dan 5 ulangan. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji wilayah ganda Duncan untuk mengetahui perbedaan antar perlakuan. Hasil menunjukkan bahwa pemberian bentonit dari berbagai level berpengaruh sangat nyata (P<0,01). Pemberian bentonit pada tingkat tertinggi (6%) mampu menekan total bakteri dan total fungi pada kisaran 105 cfu/g. Disimpulkan bahwa bentonit mampu menekan kandungan total bakteri dan total fungi pada produk pellet limbah penetasan. (Numbers of total bacteria and total fungi of hatchery waste pellets that made by adding bentonite) ABSTRACT. A Research about the effect of bentonite addition in the pelletizing process on total bacteria and total fungi of pellet product of hatchery waste as an alternative feedstuff, was done at Feed Technology Laboratory, Faculty of Animal and Agricultural Sciences, Diponegoro University. The addition of bentonite was expected to reduce the number of bacteria and fungi in the pellet product of hatchery waste, therefore, it could be used safely as an alternative feedstuff. In this experiment, the hatchery waste in the forms of eggshell, infertile eggs, un-hatched eggs, dead and culled DOC were blended, mixed with bentonite and pelleted,and then the number of total bacteria and total fungi of pellet was analyzed. The treatment was carried out with the level of bentonite i.e. 0, 2, 4 and 6% (w/w). Completely randomized design (CRD)was applied by 4 treatments and 5 replications of each. Data analyzed by analysis of variance (ANOVA), and followed by Duncan multiple range test (DMRT) to determine differences among the treatments. The results showed that administration of bentonite at various levels significantly affect the number of bacteria and fungi in the hatchery waste pellets (P <0.01). Administration of bentonite at the level of 6% shows the highest value on suppressing the content of total bacteria as well as fungi up to the range of total content 105cfu/g. In conclusion, the bentonite was able to suppress the total amount of bacteria and total fungi in the hatchery waste pellets.

Black garlic is a garlic that experiences warming at a certain temperature and time to find higher antioxidant activity. This research aimed to know effect of antioxidant content’s stability of extract BG to pH and temperature. The experimental design used in this research was a completely randomized design with replication, which consisted of two factors. The first factor was pH (4, 6 and 8). The second factor was temperature (30, 50 and 70ºC). Data were analyzed with analysis of variance, followed by Duncan test. The results showed that pH and processing temperature very influential to antioxidant activity, total phenolic and total flavonoid. The results showed that the best treatment was pH 4 and temperature 30ºC which the best resulted antioxidant activity, total phenolic and total flavonoid that stablest. The resulted of antioxidant activity, stability of total phenolic and total flavonoid that were 75,13%, 42,47% and 77,71%. The treatment of pH and processing temperature change compounds of extract black garlic. Myricetin and quercetin appeared on treatment pH 4 with temperature 30ºC and pH 8 with temperature 70 ºC. The treatment of pH and processing temperature of black garlic extract reduced antioxidant activity, total phenol and total flavonoid. pH and temperature form new compounds.

Sweetener is one of important factors which affect consumer acceptance as it affects the ice cream texture. Research on an alternative and healthier sweetener to substitute sugar in ice cream production has begun to emerge as consumers’ awareness on healthy food has been increasing. One of the promising alternatives was the utilization of Stevia leaf powder as it is known to have no calorie content. In this research, the best proportion of stevia leaf powder to substitute sugar in ice cream production was determined based on its physicochemical properties (viscosity, overrun, melting rate, sugar and total calories) and antioxidant activity. The research was done through laboratory experiment with a Completely Randomized Design consisted of four sugar and stevia leaf powder combinations and four replications. The treatments were P0 (20% sugar + 0% steviea leaf powder); P1 (17.5% sugar + 0.3% stevia leaf powder); P2 (16.25% sugar + 0.45% stevia leaf powder); and P3 (15% sugar + 0.6% stevia leaf powder). The obtained data was analyzed by ANOVA and further tested by Duncan’s Multiple Range Test upon significant effect.The results showed that the utilization of stevia leaf powder as sugar substitution gave highly significant effects (P<0.01) on ice cream viscosity, overrun, melting rate, sugar content, total calories and antioxidant activity. It can be concluded that the combination of 15% sugar and 0.6% stevia leaf powder (P3) produced the best ice cream characteristics with the viscosity of 1336.25 cP, overrun of 30.01%, melting rate of 37.24 minutes/50 g, sugar content of 34.63%, total calorie of 4.99 kcal and antioxidant activity of 81.92%.
