Sugarcane (Saccharum officinarum) is a plant that is widely used as raw material for making sugar and can be enjoyed directly by extracting the juice. While the pulp has not been utilized and is often disposed of as waste. This study aims to make compost using Trichoderma (LBKURCC1 and LBKURCC2) and Pseudomonas (LBKURCC54 and LBKURCC59) as bioactivators. The composting process is done by mixing bagasse and chicken manure with a ratio of 2: 1 and adding isolate fungus Trichoderma sp. and Pseudomonas stutzeri bacteria as activator with several combinations on compost media with 5 treatment. Compost treatment includes P0 (control), P1 (J1_J2_B1), P2 (J1_J2_B2), P3 (J1_B1_B2), P4 (J2_B1_B2) and P5 (J1_J2_B1), P3 (J1_J2_B1_B2). The process of composting bagasse is done in a poly bag. Analyzed of compost quality was determined based on parameters of temperature, water content and the levels of C/N ratio observed for 18 days. In this study, the use of Trichoderma (LBKURCC1 and LBKURCC2) and Pseudomonas (LBKURCC54 and LBKURCC59) as bioactivators in a mixture of compost material gave a significant difference to control at the C/N ratio with a value of P> 0.05. The highest C/N ratio is from P5 (28.43) and the lowest is from P2 (5.17).

Currently, most food products circulating in the community are processed using additives, both natural and synthetic. One of the potential food ingredients that can be used as a natural flavor enhancer from fishery raw materials is long jawed mackerel (Rastrelliger spp).  The purpose of this study was to studied preliminary research on the use of long jawed mackerel as an alternative material for natural non-MSG flavorings to replace synthetic flavors with a fisheries bioeconomic approach.  The procedure in this study consisted of several steps, namely the manufacture of natural flavorings from long jawed mackerel, calculation of fish yield, analysis of water content and salt content (NaCl). Based on the research results, the processing stages of non-MSG natural flavoring made from long jawed mackerel fish include the process of selecting raw materials, washing I, filling, washing II, refining I, weighing I, drying, refining II, sifting, weighing II and packaging. The amount of long jawed mackerel yield that can be used as the main raw material for the manufacture of natural non-MSG flavorings is 53% with the final weight of flavoring powder produced is 440 grams. The chemical analysis test of the long jawed mackerel flavoring was carried out 2 repetitions and the results of the water content test were 5.35% (has not met the SNI quality requirements), while the analysis of salt content (NaCl) on the long jawed mackerel flavoring has met the SNI quality requirements with a value of 12.09%. Bioeconomic analysis of fisheries is by calculating production costs and depreciation costs incurred during the processing of flavorings from long jawed mackerel. Based on the analysis, one production time produces 88 pcs of flavoring fish meat with a cost of production of Rp. 1,496 per pcs.

SummaryAn international study involving 26 laboratories assayed two candidate von Willebrand Factor (VWF) concentrates (B and C) for VWF:Antigen (VWF:Ag), VWF:Ristocetin Cofactor (VWF:RCo) and VWF:Collagen binding (VWF:CB) relative to the 4th International Standard Factor VIII/VWF Plasma (4th IS Plasma) (97/586). Estimates of VWF:Ag showed good agreement between different methods, for both candidates, and the overall combined means were 11.01 IU/ml with inter-laboratory variability (GCV) of 10.9% for candidate B and 14.01 IU/ml (GCV 11.8%) for candidate C. Estimates of VWF:RCo showed no significant difference between methods for both candidates and gave overall means of 9.38 IU/ml (GCV 23.7%) for candidate B and 10.19 IU/ml (GCV 24.4%) for candidate C. Prior to the calibration of the candidates for VWF:CB it was necessary to calibrate the 4th IS Plasma relative to local frozen normal plasma pools; there was good agreement between different collagen reagents and an overall mean of 0.83 IU per ampoule (GCV 11.8%) was assigned. In contrast, estimates of VWF:CB in both candidates showed large differences between collagen reagents with inter-laboratory GCV’s of 40%. Candidate B (00/514) was established as the 1st International Standard von Willebrand Factor Concentrate by the WHO Expert Committee on Biological Standardisation in November 2001 with assigned values for VWF:Ag (11.0 IU/ampoule) and VWF:RCo (9.4 IU/ampoule). Large inter-laboratory variability of estimates precluded the assignment of a value for VWF:CB.

Nowadays, “green analytical chemistry” challenges are to develop techniques which reduce the environmental impact not only in term of analysis but also in the sample preparation step. Within this objective, pressurized liquid extraction (PLE) was investigated to determine the initial composition of key antioxidants contained in rosemary leaves: Rosmarinic acid (RA), carnosic acid (CA), and carnosol (CO). An experimental design was applied to identify an optimized PLE set of extraction parameters: A temperature of 183 °C, a pressure of 130 bar, and an extraction duration of 3 min enabled recovering rosemary antioxidants. PLE was further compared to conventional Soxhlet extraction (CSE) in term of global processing time, energy used, solvent recovery, raw material used, accuracy, reproducibility, and robustness to extract quantitatively RA, CA, and CO from rosemary leaves. A statistical comparison of the two extraction procedure (PLE and CSE) was achieved and showed no significant difference between the two procedures in terms of RA, CA, and CO extraction. To complete the study showing that the use of PLE is an advantageous alternative to CSE, the eco-footprint of the PLE process was evaluated. Results demonstrate that it is a rapid, clean, and environmentally friendly extraction technique.

Vitamin A levels in tissues of 20 normal adult hamsters on a standard diet were measured colorimetrically. No significant difference between male and female animals was found for any of the tissues sampled. The mean vitamin A value for blood plasma in 20 animals was 53·4 μg/dl. Mean values for liver, kidneys, flank skin and cheek pouch were 813, 1·29, 1·84 and 1·31 mg/g wet weight, respectively. The vitamin assay was less suitable for small organs such as trachea.

Introduction: The denture base is the part of the removable denture that is supported by good adaptation to the underlying oral tissue. Most of the denture bases are made of acrylic or polymethyl methacrylate resin, better known as PMMA. However, the acrylic resin also has disadvantages such as easily broken and absorbs liquids both water and chemicals. The chemical absorption like alcohol, ethanol, and some drinks that contain acidic materials will chemically be induced with acrylic resin and settle in the pores of the acrylic resin. The chemical damage or defect creates roughness on the surface of the acrylic resin which can cause cracking or crazing and a decrease in surface strength and hardness. Materials and Methods: The method used in this research was a laboratory experimental design with a post-test-only control group using 12 samples consisting of 2 different types of samples by measuring the surface roughness of the acrylic resin after immersing the sample with a predetermined time. Results and Discussions: One-way ANOVA test results showed a significant difference in surface roughness after the samples immersion with a value of p = 0.006 (p <0.05). Conclusions: Based on this research, can be concluded that there is an increase in the surface roughness of the heated polymerized acrylic resin for 3 hours and 4 hours of immersion. The longer the heated polymerized acrylic resin is soaked in arak hence the level of surface roughness increases.
