Fish products perish easily due to microbial contamination. Uncontrolled thawing will increase the rate of microbial activity at every 10°C increase in temperature. One of indicator that can detect food quality is the time-temperature indicator (TTI) with changes in pH. However, these indicators are generally made of synthetic chemicals which tend to pollute the environment. This study aimed to summarize various studies on anthocyanins from agro-waste as time-temperature indicator to monitor freshness of fish products. This research used systematic literature review (SLR) from various relevant research and resources. The SLR process includes practical screening, quality appraisal, synthesizing, and reviewing. Anthocyanins derived from agro-waste than can be developed into TTI are purple yam peel, black plums peel, blueberries peel, rambutan peel, sweet potato peel, dragon fruit peel. The TTI from agro-waste anthocyanins can be developed to monitor freshness of fish products.

Gastric cancer (GC) is the most lethal disease of all cancer types. In the last three decades, it has become the most common reason for death among all cancer types. Gastric cancer is at the fourth number in all over the world and annually 8,00,000 deaths are reported. Female gastric cancer has been increased in the last 5 years. Unexpected diversity has been noted in GC spreaders in the whole world. Eastern Europe, China, and South America are the major regions of Gastric cancer prevalence. Its main sources are correlated with 2 agents, dietary intake and Helicobacter pylori infection. Although in south Asia occurrence of H. Pylori is high but less prevalence risk. The sole methods to minimize the prevalence of gastric cancer include elimination of Pylori, standard hygienic condition, proper diet, and improved living standards. One of the most common and complicated factors of gastric cancer is infection with Pylori. The main intention of this article is to elaborate the concerned review of GC and up-to-date information about its occurrence moreover its risk aspects in Pakistan.

Each student got their learning style. In skills institutions, students' learning styles are more visual and kinesthetic than auditory. This is because teachers who do not diversify the teaching system will impact their students. Besides, students will become bored and lose focus due to non-interactive teaching sessions. Teaching aids also act as a tool that can provide fun and a more profound interest in teaching content. Moreover, the application of high-tech skills that match with the era of the industrial revolution 4.0 will improve skills and knowledge. This study aims to improve the teaching quality for the Course DMC2333 Water Cooled Chiller and Air-Cooled Chiller course. In this study, researchers have chosen the ADDIE design model as a guide in developing this product. The evaluation was done using a questionnaire that has been certified by three experts in mechanical, especially in the field of Refrigeration and Air Conditioning. The items developed by the researcher are divided into three primary constructs, which are design, development, and functionality. Each section was divided into several things that help in answering the research questions. The findings found that all experts agreed with the items in the questionnaire. However, there are also comments and suggestions for improvement attached by each expert. The results of these comments and enhancements can help researchers further improve the product's effectiveness in the following study.

This study was carried out to determine the antibacterial effect of Calabash Leaf and Fruit Extracts on the preservation of lettuce affected with Escherichia coli. Additionally, this was done to assess the following: change in length of lesion on lettuce leaves depending on the effectiveness of the different concentrations of treatments; and significant difference of the extracts. The experimental research design was employed in which 2 set-ups were prepared by setting Calabash Leaf Extract and Calabash Fruit Extract. Each set-up has 3 treatments with different concentrations. The antibacterial activity of different concentrations of extracts was evaluated after 3 days of observation through interpreting the change in the size of the 1 mm purposively-made lesion on lettuce leaves. The investigations were focused on the damaged part measured. t-test results revealed that the t-value calculated was smaller than the critical value at a 5% level of significance, thus the difference is not significant. These findings revealed that the Calabash extracts equally possess a high antibacterial effect against Escherichia coli. The Calabash Leaf and Fruit Extracts can potentially be considered as an alternative tool to prevent plant-tissue deterioration and to prolong the shelf life of crops and vegetables.

Acne is a problem among teenagers generally caused by bacterial infections such as Propionibacterium acnes, Staphylococcus aureus, and Staphylococcus epidermidis. Mugwort (Artemisia vulgaris L.) and Gotu Kola (Centella asiatica L.) extracts have antibacterial activity formulated in anti-acne gel preparations. The purpose of this study was to test and obtain a gel formula of mugwort leaf extract and gotu kola leaf extract which effectively kills and controls the growth of acne-causing bacteria. The methods used in this study include simplicity making, leaf extraction, making anti-acne gel preparations, testing pH, homogeneity, inhibition, and data analysis. The extract obtained by maceration was made in three concentrations, namely 2.50; 5.00; and 10.00%. The results showed that the pH value of the gel preparations obtained was in the range of 8.08-9.96. Mugwort leaf extract, gotu kola leaf, and mugwort-gotu kola have a distinctive smells with a thick texture at a concentration of 2.50% and a liquid texture at a concentration of 10.00%. Inhibition tests showed that the mugwort extract sample had a value of 16-18 mm, while the gotu kola extract and mugwort-gotu kola had a value of 14 mm. Mugwort leaf extract is able to inhibit the growth of acne-causing bacteria. This success was obtained because the extracts of mugwort and gotu kola leaves contain flavonoids that can inhibit the growth of bacteria that cause acne. Mugwort leaf extract gel with a concentration of 2.50 and 5.00% had the largest zone of inhibition in inhibiting P. acnes bacteria compared to other concentrations.

This study aims to determine the possibility of organic mosquito patches as an alternative to mosquito repellents. The results showed that the control group, namely commercial mosquito patches, was able to obtain the highest rate of repelling mosquitoes. However, statistical analysis did not show a significant difference in the three patches. Thus, the manufacture of organic mosquito patches is as effective as commercial mosquito patches at repelling mosquitoes. In addition, organic mosquito patches have the most economical product compared to commercialized patches. Thus, making organic mosquito patches is not only as effective as commercial mosquito patches but also much more affordable than they cost. It is recommended to use an organic mosquito patch as an alternative to mosquito repellent.

This study evaluated the bioactive compounds present in the ethanol leaf extract of Eucalyptus tereticornis as well as its antioxidant potential using standard biochemical methods. The leaf extract contains rich number of bioactive compounds (Phenol 109.41± 0.10GAE/g, Flavonoids 33.10± 0.01mgCE/g, Beta-carotene 3.16± 0.00mg/g and Lycopene 0.32± 0.00mg/g). The antioxidant potentials were evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical, iron-reducing power, inhibition of lipid peroxidation, and nitric oxide scavenging antioxidant systems. The antioxidant activities of the plant extract increased with an increase in concentration. The extract showed high potency in DPPH and nitric oxide free radical scavenging activity compared with the known vitamin C antioxidant potentials. A high reducing power indicative of a high proton (H+) donating potential with a high inhibition of lipid peroxidation portrays a high potent antioxidant activity that protects cells from deleterious effects of free radicals which accounts for its medicinal use. The general results indicated that the plant is rich in bioactive compounds which are believed to have contributed to the high antioxidant activities observed and its medicinal value.
