This study was conducted to compare handwashing using soap and hand sanitizer to kill germs on hands. Hand washing is one of the preventive measures to avoid various diseases that can be transmitted through hands. In addition, the COVID-19 pandemic which has attacked almost all over the world has forced various levels of society to pay more attention to hygiene, especially hand hygiene which can be a bridge for the spread of the virus. The research conducted in this article uses qualitative research methods based on reviews and analysis from several journals related to the comparison of the effectiveness of handwashing using soap and hand sanitizer. The results showed that there was a difference in the number of microorganisms in the hands before and after washing hands. Soap and hand sanitizer can eliminate microorganisms because both of these ingredients contain ingredients that can reduce the number of harmful bacteria in the hands such as alcohol and triclosan. From the analysis of several journals related to the effectiveness of handwashing using soap and hand sanitizer can be concluded that hand washing using soap and water is considered more effective to eliminate microorganisms on the hands than just the use of hand sanitizer.

Digestive health literacy is important for students to be able to determine their diet, choose healthy foods, prevent and know the actions that need to be taken in treating diseases or disorders of the digestive system, and even promoting healthy living behaviors to others. This study aims to develop instructional designs to improve student health literacy with the ADDIE model. The development carried out consisted of developing lesson plans, assessment instruments, and learning media DD Mag'z (digestive disease magazine). Based on the results of the analysis, the learning design was determined using DD Mag'z and Google Meet synchronously. Expert validation was carried out assessing three aspects consisting of the feasibility of media, content, and language. The results of the validation of the developed media obtained an average value of 3.58 and were included in the very valid category so that it was suitable to be used as an alternative learning media on the concept of the digestive system. Measurement of the improvement of students' digestive health literacy skills used a dual choice instrument as a pre-test and post-test. The effectiveness analysis used a one group pre-test post-test design and obtained data that were not normally distributed. The Wilcoxon test results showed an effect of the synchronous use of DD Mag'z media with Google Meet on students' health literacy. While the results of the effectiveness test using N-Gain showed an average value of 0.41 so that the effectiveness of the instructional design developed was moderate.

Seaweed is widely used in many industries such as cosmetic foods, and drugs resulted in its increasing demand. To complete the market demand, it is necessary to escalate the seaweed cultivation. One of the problems of cultivation is the availability of the seed. The conventional and vegetative system of seaweed seed reproduction in the form of direct fragmentation or thallus cutting affects the degradation of seed quality. Therefore, another system of reproduction must be performed. One of the best ways to multiply the plants is tissue culture technique. Tissue culture is a plant multiplication technique using the artificial medium in a controlled and sterilized environmental condition. The advantage of this technique is the seeds will be all even, pathogen-free, numerous in one single production, and not influenced by any season. Some methods used in seaweed tissue culture are protoplasm culture, spore culture, and somatic embryogenesis. The government takes a serious action in seaweed industry by releasing the regulation of seaweed research and development through Presidential Regulation No. 33 of 2019 about the roadmap of National seaweed industry development 2018-2021. Therefore, the research and development of seaweed tissue culture is still widely open for its underexplored potential. On the other plants, this technique has reached the utilization stage to produce bioactive compounds e.g. the increasing production of saponin in Javanese ginseng callus culture. Based on that reason, the tissue culture technique can be implemented to search seaweed’s bioactive compound potential.

Test Content Calcium Carbonate (CaCO3) On The Shell Of The Golden Snail (Pomaceae Canaliculata) As Anticide Substance Nida Hamidah; Lily Aprilia; Aprilia Nur Hidayah; Ika Sukmawati

Antacids are weak bases that are used to treat gastrointestinal conditions caused by increased gastric acid secretion. Calcium carbonate is a common antacid (CaCO3). As is well known, the golden snail shell is almost entirely composed of calcium carbonate. As such, we tested the calcium carbonate (CaCO3) content in the shell of the golden snail (Pomaceae canaliculata) as an antacid substance in this study. The study was conducted empirically in four stages: preparation, XRF test, XRD test, and antacid simulation test. As a result, the golden snail's shell (Pomaceae canaliculata) contains up to 50.4161 percent calcium oxide (CaO), which has the potential to be used as a starting material for calcium carbonate extraction (CaCO3). The XRD diffractogram at 500 degree celsius shows that pure CaCO3 was produced with a typical diffraction pattern at 2 theta: 26.16 degree and 27.12 degree. Additionally, it is well established that the calcium carbonate (CaCO3) found in gold snail shells can neutralize acid. However, additional research on the use of calcium carbonate in golden snail shells (Pomaceae canaliculata) as an antacid is necessary to determine the optimal dose for successful stomach acid neutralization.
