Traceability of Halal Control Point in Material, Production, and Serving to Support Halal Certification in Universitas Brawijaya Canteen

Halal food certification in the university canteen needs to prepare Halal Assurance System (HAS) implementation. Halal Control Point (HCP) traceability in the canteen is very complicated because it has several menus, processes, and materials. This study aims to trace the HCP on materials, processing and serving in Universitas Brawijaya (UB) Canteen, then provide improvement. This research used seven criteria of HAS-23102 for a restaurant to evaluate the menus, ingredients, production, and serving in UB Canteen. HCP traceability was done on 60 menus from 4 food tenants and one beverage tenant. The results showed that grouping the menus and ingredients facilitates HCP identification. The menu consists of six groups: soup, deep-fried, stir-fried, strong spices dish, medium soup, and beverages. The materials consist of fresh ingredients, dry ingredients, and liquids. The menus required 113 materials. There are 16 (14%) materials HCP, including chicken, beef, noodles, and soy sauce. HCP materials do not meet HAS criteria and be replaced with halal-certified material or halal production process (HPP) description from the producer that needs to be checked by a halal auditor. The HCP did not found in the process and serving because the canteen does not produce and service haram (unlawful) products. Still, there is contamination possibility of haram and najis (unclean in Islamic terms) materials. For prevention, the Standard Operational Procedure (SOP) of production, serving the tenant, employee, and visitor need to be applied. The alternatives are supplying chicken meat and beef from a halal-certified slaughterhouse, monitoring and controlling the tenants' kitchen periodically three months, applying the halal standard for storage in tenant's kitchen and canteen facilities, and food serving in canteen. The HCP traceability of the university canteen according to halal standards, including raw materials, additional materials, processes, and serving, including the equipment used.

Comparative Study of Satisfaction and Acceptability between Using Menstrual Cup versus Sanitary Pads in Health Care Personnel: A Randomized Crossover Trial

Background: In the past decade, menstrual cups (MC) have become increasingly popular in many countries but there was no previous reporting on MC usage in Thailand. Objective: To evaluate and compare the satisfaction and acceptability of using MC and sanitary pads (SP) in health care personnel (HCP). Materials and Methods: Participants were HCP in Bhumibol Adulyadej Hospital who were willing to participate in the study between October 2019 and March 2020. They were randomly assigned into groups A and B. During the first three cycles of menstruation, participants in group A and B used SP and MC, respectively. In the later three cycles of menstruation, they were switched from SP to MC and vice versa. The demographic and menstrual characteristics were recorded. Satisfaction was evaluated by using the five-point Likert scale. Acceptability of MC usage was recorded on the sixth cycle questionnaire. Results: Ninety-eight HCP were recruited and equally divided into two groups (A and B). Acceptability for MC was significantly lower than SP (89 versus 100 percent, respectively). Participants who had regular sexual intercourse had more acceptability with MC than those who had no regular intercourse (98.4 versus 68.7 percent, respectively). Participants reported more significant satisfaction for MC than SP in terms of leakage prevention, cleaning, odor prevention, land activity, daily activity, comfortable sleep, and overall satisfaction. Contact dermatitis associated with MC was less than with SP with a statistically significant difference. Conclusion: Acceptability for MC was lower than SP. MC’s acceptability was preferred among HCPs with regular sexual intercourse. MC had higher satisfaction and less side effects than SP.

Dipolar HCP materials as alternatives to DMF solvent for azide-based synthesis

Hypercrosslinked polymers HCP-DMF and HCP-DMF-SO3H that contains abundant and flexible DMF moieties were designed and synthesized. Benefitting from the solvation microenvironment provided by the pseudo-DMF moities, the polar HCPs manifested...

Effect of Prestrain on Precipitation Behaviors of Ti-2.5Cu Alloy

As a special hardenable α titanium alloy, Ti-2.5 Cu alloy was a candidate material for high temperature components requiring high strength and plasticity. The effect of prestrain on the precipitation behaviors was investigated in the present study. Tensile tests show that elongation up to 22 % can be obtained after solid solution (SS) treatment. Thereafter, prestrain in tension with 5 %, 10 %, 15 % and 20 % was carried out for the SS samples and then duplex aging was applied. Transmitting electron microscopy (TEM) investigations show that larger Ti2Cu particles were observed in the prestrained condition than free aging one, as prestrain significantly speeds up the precipitation kinetics. The strength firstly increases and then decreases for the prestrained samples after duplex aging, where the competition between precipitation hardening and recovery softening should be responsible. With the consideration of SS, precipitation and recovery, a strength model for duplex aging combined with prestrain was established, which is in well agreement with experiments. Present study may provide a promising way to obtain the strength of deformed hcp materials in industry application.
