Synthesis and Characterization of Chitosan- Alginate for Controlled Release of Isoniazid Drug Sari Edi Cahyaningrum; Nuniek Herdyastuti; Nur Qomariah
Indonesian Journal of Chemistry Vol 15, No 1 (2015)
Publisher : Universitas Gadjah Mada

The aim of this research was to synthesize and characterize chitosan-calcium alginate as matrix isoniazid encapsulation to produce controlled release isoniazid drug. The microparticles were evaluated for surface morphology, functional groups, size particles, drug content and swelling index. The drug release kinetic was investigated at gastric and intestinal artificial pH. The results showed that isoniazid-calcium alginate-chitosan has majority particle diameter of 1001-1500 nm. The release mechanism of isoniazid was through combination of erosion and diffusion.

Publisher : Universitas Gadjah Mada

In this study, papain was immobilized on chitosan with Mg(II) cosslinked agent. Studies on free and immobilized papain systems for determination of optimum pH, optimum temperatur, thermal stability and reusability were carried out. The results showed that free papain had optimum pH 6.5 and optimum temperature 55 °C while the immobile papain hadoptimum pH 8 and optimum temperature 80 °C. The thermal stability of the immobilized papain, relative to that of the free papain, was markedly increased. The immobilized papain can be reused for at least six times.

UTILIZATION OF Penaus monodon SHRIMP SHELL WASTE AS ADSORBENT OF CADMIUM(II) IN WATER MEDIUM Sari Edi Cahyaningrum; Amaria Amaria
Indonesian Journal of Chemistry Vol 5, No 2 (2005)
Publisher : Universitas Gadjah Mada

Utilization of shrimp shell has been optimum so that in this research preparation of adsorbent chitosan from shell of shrimp (Penaus monodon) as raw materials for cadmium(II) adsorption was carried out. The chitin was made by the deproteination, demineralization; chitosan was prepared by chitin deacetylation. This work was started with Infra Red Spectroscopic identification of functional group. Percentage of deacetylation was determined also by Infra Red Spectroscopy. Contant of nitrogen was determined by Kjeldhal method. The isotherm adsorption Langmuir model was employed for the determination of the energy and the capacity in adsorption. Result showed that chitosan could be isolated from shrimp shell waste with % deacetylation degree of 79.80 and % nitrogen 7.11. Cadmium(II) was chemically adsorbed on chitosan involving energi adsorption of 32.27 kJ/mole. Adsorption capacity of cadmium(II) was 6.35 x 10-5 mole/g. The constant adsorption rate k, was 0.91 x 10-3 s-1 and equilibrium adsorption desorption are K = 10.28 x 103. The ability adsorption of chitosan in real waste has the efficiency of 90%.

Livelihoods the people of Sidokare village, Rejoso sub-district, Nganjuk regency are mostly farmers. In addition to planting rice, they also plant shallots which are their signature product. Most of the women in Sidokare village are housewives who are also farmers and farm labourers. However, during the period between the planting season and harvest season, most of them are unemployed and have no income. This is certainly a burden for the family's economy, in addition to the Covid-19 pandemic that causes the price of harvest to be uncertain while the daily needs must still be met. The purpose of this community service activity is to provide training and assistance in the production of home industry scale soap products while still paying attention to the quality that meets health standards by utilizing herbal ingredients. This activity is expected to equip women in Sidokare Nganjuk Village with skills in making home industry soap products that can be used as business startups to support the family economy. As a result of this activity, the community gains skills to produce various liquid soap products that can be marketed in their neighbourhood.

This research aimed to describe the effectiveness of differentiated learning materials oriented toward the nature of science (NoS) to improve studentsâ€™ scientific literacy skills. The research type is quasi-experiment with one group pretest-posttest design. The research was given to 31 students in VIII-A class of Junior High School 16 Gresik. The effectiveness of differentiated learning materials oriented toward the nature of science (NoS) was obtained from the scientific literacy skills test and student response questionnaire. The studentâ€™s scientific literacy skills test showed an improvement in gain score between the pretest and posttest scores of 0.64, which is in the medium category; besides that, most students gave positive responses to the learning materials seen from the percentage of interest in learning materials 84.68% (very interested). The data obtained showed that differentiated learning materials oriented toward the nature of science were effective as learning materials to improve studentsâ€™ scientific literacy skills in Merdeka Curriculum

Hydroxyapatite is an inorganic material that is commonly used as a re-mineralizing agent. Adding natural ingredients such as green betel leaf can increase the antibacterial properties due to the presence of phenolic compounds, flavonoids, and tannins. This study aims to determine the physical and chemical characteristics of the formulation of hydroxyapatite-betel leaf extract and the antibacterial activity against Streptococcus mutans. To characterize the combination of hydroxyapatite-betel leaf extract, XRD, PSA and FTIR analyses were performed. Particle size analysis showed the smallest results in the variation of betel 0.3 g, which is 690.08 nm. FTIR characterization showed the presence of OH, PO43− and CO32− functional groups from hydroxyapatite and C=O derived from betel leaf extract. In addition, in vitro and in vivo analyses were performed to assess the antibacterial activity of this formulation. The in vitro antibacterial activity test against S. mutans showed strong inhibitory activity. Our finding suggests that the formulation has the potential to be used as a medication or prevention agent for dental caries.
