Abstract

Iron (III) (Fe (III)) is widely used in the industry such us water treatment, the sugar cane, the concrete industry and coal mining. Industrial activity using Fe(III) has potential impact to environmental pollution problems due to that industry produces Fe waste that one of hazardous waste. Fe content excess might toxic effect to human health and the environment. Zeolite as adsorbent has been evaluated extensively for Fe and other heavy metal. Sonication method has been widely developed in polymer preparation. The method is more effective in operation time because the reaction rate increased and also more efficient on the usage of chemical reagens. The optimization of reaction time, the ratio of Fe(III) with activated zeolite, the influence of pH, and temperature has been assessed for Fe(III) adsorption with an activated zeolite by sonication technique. The formation of Fe(III)-SCN complex assay was used for determination of Fe(III) adsorbed by the activated zeolite with using spectrophotometer. The results showed a relatively short operation time (15 minutes), at pH of 4, temperature of  30 °C with the ratio of 1:50 (weight/volume) for the activated zeolite and Fe(III).

Abstract

Organic chemistry learning materials about writing the structure of organic chemistry molecules, pictures of simple practical tools are obstacles in learning chemistry. This is due to the lack of technology-based skills to make it easier to write this material in teaching materials. One of the superior teaching methods that needs to be taken into consideration is the provision of multimedia-based teaching materials and supporting facilities. It is hoped that the availability of technological facilities and multimedia teaching materials will make it easier for students to understand the material/lessons. Strengthening the ability to master multimedia-based teaching materials is still hampered by the lack of skills in making KingDraw software teaching materials. Apart from that, the partner has 3 chemical laboratories but does not have a comprehensive insight into natural reagents for chemical analysis that can be used for chemistry practicum. Therefore, in this community service program scheme, the proposer provides several solutions and programs to provide development training. learning media/teaching materials through KingDraw software and introduction to natural reagents for chemical analysis at SMK Bhakti Kencana Cimahi. Strengthening students' competencies by applying the application of natural ingredients as reagents for chemical analysis can help with laboratory practicums in chemical analysis subjects. Thus, this community service activity can be useful for schools to improve the quality of teachers in updating knowledge based on KingDraw software technology to develop teaching materials.

Abstract

Background: Mycobacterium tuberculosis which is resistant to isoniazid (INH) occurs due to gene mutations, mostly in the katG gene. Primers have been found to identify mutations in the katG gene that occur with varying lengths of primer products. However, this has not been proven laboratory-wise. Varying TAE buffer concentrations of 0.5x, 1x, and 1.5x were carried out, and repeated use of TAE buffer. This is to see the effect of concentration variations on the quality of the Mycobacterium tuberculosis DNA band. Method: The type of research used was quasi-experimental. The research subjects used were TAE buffer solution with concentrations of 0.5x, 1x and 1.5x which were used repeatedly at the electrophoresis stage. The examination material was Mycobacterium tuberculosis DNA resulting from PCR. Visualization of electrophoresis results on all samples compared to the size of the ladder used and all products produced are at the appropriate base pair size. Using the ImageJ application in the DNA size analysis process is an alternative that can help assess the size of DNA bands. Research Results: In the results of the research carried out, it was found that the DNA band of Mycobacterium tuberculosis which is resistant to the isoniazid (INH) katG gene for MDR TB is at codon 315 with a product size of 101 bp S315T, 141 bp S315N, 200 bp S315I, 247 bp S315R, 290 bp S315G and 400 bp R463L obtained DNA band density on electrophoresis using a TAE buffer concentration of 0.5x, shown by the highest area formed compared to concentrations of 1x and 1.5x, and from repeated use of TAE buffer twice, visualization of the DNA bands was obtained. still good, it just affects the area of ??the DNA band when read using the ImageJ application. Conclusion: 0.5x TAE buffer concentration is able to provide the highest area compared to 1x and 1.5x TAE buffer concentrations. The repetition process does not affect the visualization of the DNA bands but does affect the smaller area formed.

Abstract

The use of brazilien for borax detection is because the chemical properties of this compound are greatly influenced by pH which results in a change in the color of the brazilien. This compound gives an orange color at a pH range of 6-7 and yellow at an acidic pH, while at a pH range of 7-10 it gives a red color and at a pH >10 it gives a purplish red color. This research uses Brazilian extract from sappan wood for borax detection. By utilizing this compound extract, the use of chemical reagents for the detection of borax in food samples can be minimized. Apart from that, it can increase the added value of these crop commodities and can take advantage of the abundant natural resources in Indonesia. This research aims to develop a method that is accurate, simple and cheap and does not use special instruments to diagnose borax based on digital imaging, which includes extraction of brazilien from sappan wood using a maceration method using 96% ethanol solvent and water with a UV-Vis spectrophotometer, ratio optimization brazilin extract with boric acid, optimization of measurement time. The results of the research show that the solvent that provides optimum absorbance for brazilin extraction is water or distilled water, with a ratio of brazilin extract and boric acid of 1:1 and the measurement time is 5 minutes.

Abstract

Consuming foods containing borax (tetraborate) will cause health problems. However, in reality, borax is often added to foods such as crackers, meatballs, wet noodles, dumplings. These foods are usually produced by unregistered public members, so their quality is less controlled, so routine monitoring of borax levels in food is needed so that the food quality circulating in the community is maintained and safe for consumption. This research aimed to develop simple method that does not use special instruments to diagnose borax using a Paper Analytical Device (PAD) based on digital imaging using natural reagents from purple sweet potato extract. The research design was laboratory research and development (RnD). The research was conducted at Poltekkes Kemenkes Bandung in January-June 2022. The samples used were borax samples at concentrations of 100, 300, and 500 ppm. The research method was PAD based on digital imaging using Image J. This research was carried out by extracting anthocyanins from purple sweet potatoes, then optimizing the anthocyanin concentration extract; pH; measurement time, determining measurement linearity, and validation by determining % recovery. The research results include that the optimum pH is 9. Optimized measurement time is 3 minutes and is stable until the 5th minute, the linear concentration range of tetraborate is 100-500 ppm tetraborate. In the validation test of the PAD method, a recovery percentage of 87.58-87.95% was obtained for 200 and 300 ppm tetraborate samples. The research result will be able to diagnose and monitor borax in food.

Abstract

Stunting itself is a condition of failure to thrive in children (body and brain growth) due to long-term malnutrition. This disorder is characterized by a child's height being stunted or much shorter than their peers. In addition to the lack of nutritional intake in food, it turns out that stunting can be influenced by the adequacy and safety of drinking water and sanitation. According to WHO, the provision of safe drinking water and sanitation determines human life and life. These two basic needs can reduce the disease index by 0.39%. Without safe water and sanitation, children become vulnerable to stunting. Clean water that meets health requirements must be safe in terms of physical, chemical, microbiological and radioactivity. Most people living in urban areas do not use clean water from the Regional Drinking Water Company (PDAM), but to get clean water, people try to make dug wells or drilled wells for their daily needs. In terms of quantity, this can be met, but in terms of quality, this is less noticed by the community. From the results of observations in the field, yellow water was seen from several residents' houses. The cause of the yellow water is the presence of iron (Fe) and organic materials (KMnO4). In this activity, participants who can participate are active students. The selection of students as the target community in this activity is based on considerations of their social roles in society. Students, in their functions and roles in society are agents of change, social control, strong future generations (iron stock), and role models (moral force). Based on these functions and roles, it is hoped that after participating in this educational activity, students will be able to become guardians, reminders and mouthpieces for the information presented in this educational activity to the community so that they can prevent stunting.

Abstract

Background Mueller-Hinton agar (MHA) is widely used for disk diffusion tests to assess antibiotic susceptibility in non-fastidious bacteria. The type of water used to prepare the MHA may have affected the test outcomes. Objective This study evaluated the effect of different water types as solvents on the antibiotic susceptibility test results of tetracycline and gentamicin against Staphylococcus aureus. Methods MHA was prepared using four types of water: distilled (control), bottled, reverse osmosis (RO), and municipal tap water (PDAM). Antibiotic susceptibility testing was performed using the Kirby-Bauer disk diffusion method, and data were analyzed using One-Way ANOVA and Tukey’s Post Hoc test. Results The mean inhibition zones for tetracycline were 23.8 ± 0.99 mm (distilled), 23.4 ± 0.37 mm (bottled), 23.0 ± 0.43 mm (RO), and 17.8 ± 1.41 mm (tap), categorized as sensitive except for tap water (intermediate). For gentamicin, the zones were 11.7 ± 0.37 mm (distilled), 12.7 ± 0.77 mm (bottled), 9.8 ± 0.18 mm (RO), and 17.6 ± 1.19 mm (tap), with the first three classified as resistant and tap water as sensitive. The tap water results were significantly different (p<0.05) from those of the other antibiotics. Conclusion The use of non-standard solvents in MHA preparation, particularly tap water, may lead to inconsistent antibiotic susceptibility results. Standardized use of distilled water is recommended to ensure test accuracy and reliability.
