Abstract

Black cumin (Nigella sativa, L.) is a plant with a lot of advantages. Many research have been conducted on this plant and most of them use nonpolar, such as petroleum ether and chloroform, as a solvent in extraction process. In this research, extraction of black cumin using ethanol was applied.Black cumin extraction started with maceration using ethanol p.a. and partition using chloroform (1:1). The antioxidant activity of ethanol fraction of black cumin was examined by DPPH method. To identify the composition, phytochemical screening, including test for terpenoid, flavonoid, saponin, tannin and alkaloid, was also conducted.The result showed that the scavenging ability on DPPH method was 22.483% with IC50 2743.59. Phytochemical screening on ethanol fraction showed the presence of flavonoid, tannin and alkaloid. The study concluded that polar fraction of black cumin has small antioxidant activity.

Abstract

Gelatin, a proteinaceous additive, is obtained from hydrolysis of collagen in the bone, hide and skin of animals. As natural product, gelatin has been applied in many industries with various functions. This study attempt to characterize gelatin profile of broiler chicken (Gallus domestica) using SDS-PAGE electrophoresis. The chicken bone was pretreated using a strong base, sodium hydroxide, producing type B gelatin. The gelatin was purified through precipitation using the variation of ammonium sulfate concentrations (40-70%) and dialysis using cellophane membrane. The purified gelatin was characterized through SDS-PAGE electrophoresis. Based on electrophoresis visualization, reduction of band intensity by ammonium sulfate 40% showed removal of small peptide fragments. The remained gelatin showed two major bands, α-chains and a β-chain with the respective molecular weight of ~135 and ~245 kDa. The protein content of the unpurified gelatin (E1) was 71.65±0.60 mg/L.  The purified E1 gelatins by 40-70% of ammonium sulfate addition contained 61.42±3.90, 60.45±1.36, 59.89±0.24, and 55.32±1.05 mg/L of protein concentration, respectively. Keywords: chicken bone, gelatin profile, protein electrophoresis

Abstract

Black garlic is a traditional spice having potential of herbal medicine; however, continuous heating darkens its color and changes its taste due to chemical processes and new equilibrium in the system. In this study, fresh garlic was processed into black garlic at 60 °C for 24 days. Changes in physical and chemical parameters, such as browning and protein content, reducing sugar content, and antioxidative components were recorded. Protein content was measured by Kjeldahl method, brown color development was analyzed using a color reader, reducing sugar was examined using a dinitro salicylic DNS reagent, and antioxidative activities were studied with a diphenyl picrylhydrazyl DPPH reagent in terms of their percent inhibition. Gas chromatography – mass sepctrometry (GC–MS) and Liquid Chromatography-High Relosultion Mass Spectrometry (LC–HRMS) were performed to determine the chemical profiles. Results showed a number of interesting features. The protein and sugar contents increased up to 3 and 4 times that of the initial values, respectively during processing. The antioxidative properties improved in the later stages. The chemical profiles of volatile and nonvolatile components were altered in their final stage. Sulfur and nitrogen-containing nonvolatile components were relatively stable during heating, but their compositions changed. The natural chemical changes reflect the biological potential dynamics in biological processes as herbal supplements. The reflection of the processes might go further into food chemistry and the food industry. This needs an interdisciplinary approach, expanded to biological concepts and safe, ethical industrial processes.

Abstract

Education plays an important role in shaping individual character and abilities. Thematic learning, which combines several subjects under one theme, is increasingly popular. This research explores the implications of thematic learning in grade 5 of SD Wonorejo, Pekalongan Regency. The aim of this research is to describe the implications of class V thematic learning at MI Salafiyah Wonorejo. This research method uses descriptive qualitative, data collection through observation, interviews and documentation. The research results explain that thematic learning environments are carried out both inside and outside the classroom. Thematic learning uses varied learning. This varied learning is adapted to student characteristics. Thematic learning as an integration approach naturally connects facts and ideas in an effort to understand the world. Through a theme network, students can connect ideas with experiences and the environment where students live. The implications of thematic learning include teacher creativity, active student participation, and the use of integrated textbooks. This research is relevant for improving the quality of education by designing more effective learning strategies.

Abstract

During the early age range, children experience rapid development in various aspects. Seeing the importance of this period, appropriate stimulation efforts from the environment are needed to optimize the development of all abilities of children, including the ability to begin reading. Kindergarten children have begun to be taught to read the beginning but must be in accordance with the stages of child development, without coercion, in a fun way and should be guided by the teacher because it basically provides learning to start reading in early childhood must be with a playful atmosphere pleasant and no pressure. But in reality the process of learning to begin reading in kindergarten is still rampant using reading learning strategies that are too academic and rigid like in Elementary Schools. Therefore, researchers designed an educational game called Happy Ball that uses picture word cards. Through this Happy Ball game, it is hoped that the atmosphere of early reading learning activities for young children will be interesting and fun, the ability to read the beginning of the child is expected to be directed and develop better in a happy atmosphere. It is hoped that this game can also be used by educators to develop early reading skills in early childhood.
