Diabetes Mellitus merupakan suatu penyakit kronis karena tubuh tidak dapat memproduksi insulin dengan cukup, oleh karena itu hiperglikemia adalah ciri khas Diabetes Mellitus. Menurunkan kadar glukosa darah perlu Perawatan dengan pharmalogicall dan nonpharmalogically. Salah satu pengobatan diabetes mellitus tipe 2 dengan non-farmalogik adalah daun salam. Daun salam merupakan tumbuhan alami yang mudah didapatkan, memiliki kandungan flavonoid yang dapat menurunkan kadar glukosa darah. Adapun tujuan penelitian ini untuk menganalisa pengaruh penerapan rebusan daun salam terhadap kadar gula darah penderita diabetes mellitus. Jenis penelitian ini adalah quasi eksperimen dengan desain Non Equivalent Control Group Design. Besar sampel 36 responden dengan tehnik sampling purposive sampling. Penelitian ini dilakukan di Desa Kopek Kecamatan Godong Kabupaten Grobogan. Uji statistik yang digunakan pada penelitian ini yaitu uji Wilcoxon.

The prospect of A. calamus extract to be botanical insecticides to control the insect pests is very promising. The insect control properties of the A. calamus are predominantly to have β-asarone, saponin and flavonoid. However, there are some factors limiting their efficacy. Short release rate at the point contact, the inherent volatility and vulnerability to oxidation and ultra-violet light are causing phytochemical changes during the application. Thus developing nanotechnology to increase their efficacy studied in this research. To develop the plant extract in nanoformulation, experiment on adsorption and desoption capacity were carried out with Acorus extract treated bentonite substrate analysed by GC techniques. In addition, to investigate the effectiveness of the plant extract treated bentonite were evaluated on Crocidolomia pavonana. Third instar larvae were used in the evaluation of antifeedant effect by using no choice methods. The results showed that Bentonite nanoparticles was effective in controlling the release of a bioactive element. Purifed clay bentonite for getting Na-bentonite increased the specific surface area of material therefore increased the adsorption site on the clay layer of the material. Crude extract of A.calamus can dissolve well in combination of water and organic solvents. Desorption experiments proved that Na-bentonite released more slowly than raw clay bentonite. Purification of bentonite to Na-bentonite resulted the changing of phytochemical properties bentonite which lead to an increase in the adsorption capacity of bentonite. In term of antifeedant evaluation based on damage to cabbage leaves seedling, the least damage was observed on leaves with nanoparticle plant extract formulation. The antifeedant index of A. calamus in nanoparticles formulation showed 25% higher that untreated cabbage plant seedling. The glasshouse trial was conducted to evaluate their efficacy on cabbage seedling. However, the brown leaves or phytotoxic effect has been found by the time the extracts nano formulation has been sprayed.

The protein adsorption was interesting study, especially in the biological fluidic application. In the present study, we study the protein adsorption behavior on the bacterial cellulose and modified bacterial cellulose. In here, bacterial cellulose was modified by acid hydrolysis using hydrochloric acid. The contact time and pH were used as variable to study protein adsorption behavior on the modified bacterial cellulose. As the results, based on functional group analysis, there are not different between bacterial cellulose and modified bacterial cellulose. However, after modification, there was increasing of crystallinity of bacterial cellulose from 84.5% to be 87.7%. In the protein adsorption study, increasing the contact time increase percent adsorption until contact time of 90 minutes, however the further contact time relatively constant. The protein adsorption on both of bacterial cellulose and modified bacterial cellulose decreases, following the increase of pH.

SMAI Gumukmas is a privately-funded high school situated in Purwoasri Village, Gumukmas District, Jember, with a B accreditation status. The absence of laboratory resources challenges devising inventive, uncomplicated, and pragmatic classroom learning, such as Chemistry. Collaboration between SMAI Gumukmas and the Chemistry Department lecturers to conduct community service is a mutually beneficial initiative that fosters curriculum innovation and practicum subjects. Acid-base is a chemistry topic with material relevant to all grade levels and can be easily visualized through practical examples from everyday life. The methodology involves delivering a lecture or theoretical framework on acid-base, followed by practical work. The acid-base practical is designed to commence with comprehension of the acid-base concept, including everyday life examples, before progressing to classroom implementation. The acid-base theme learning activities and practicum at SMAI Gumukmas proceeded seamlessly and successfully. The initial class consisted of 40 students from grades 11 and 12, while the subsequent consisted of 33 grade 10 students. The students exhibited a positive response as their studies progressed with exemplifications derived from everyday life.

Water is a basic need for all living organisms. Water quality implies living quality. Several parameters influencing water quality include minerals, dissolved organic substances, and turbidity. The water consumed must meet proven water quality standards. However, water quality still needs to be improved in several areas before consumption. The well water in residential areas placed on rice fields generally needs to meet the requirements for consumption. Many Taman Gading housing complex residents, especially in RW 036 RT 006, still use the well water to meet their daily needs. The well water quality in this area tends to be smelly and somewhat misty. Proper treatment is needed to improve the quality of well water in this area to reduce the negative impact on the population's health in the long term. This training focused on well water purification and filtration using slow sand filtration technology (SPL) to improve water quality. This method uses activated charcoal, sand, gauze, and pumice as filter media in specific proportions. The use of this method is effective and efficient in reducing the turbidity level of the sample water to the threshold for drinking water (<500 ppm), with a neutral pH (close to 7.00). This technology is effortless for residents to use and apply independently at a relatively low cost.

One of the factors that determine the formation of the membrane is the solution in the coagulation bath (non-solvent). In this study, the effect of pH treatment on the coagulation bath solution on membrane formation and its effect on membrane performance will be studied. The pH of the coagulation bath used was pH 1, 6.8 and 12. As the results, physically the three pH treatments produced the same white (opaque) membrane. Through morphological analysis, it appears that the three pH treatments produced an asymmetric membrane consisting of a top layer and a sublayer. The surface of the membrane with pH 1 treatment showed a denser surface than the pH 6.8 and pH 12 treatments. The results of the membrane performance characterization showed that the membrane permeability coefficient of the membrane with pH treatment was in the following order pH 1 < pH 12 < pH 6.8. While the value of the rejection coefficient showed that the membrane treated at pH 1 did not detect rejection because there was no permeate coming out, while at the treatment at pH 6.8 and 12, the rejection coefficient values were 74% and 76%, respectively.

Hydrogen sulfide (H2S) is a toxic, corrosive, and flammable gas. The presence of H2S gas can be reduced by a permeation method using PTFE (Polytetrafluoroethylene) membranes and PVDF (polyvinylidene fluoride) membranes. This H2S gas passed through the membrane and was then captured by the SAOB (Sulfide Anhydride Oxidant Buffer) in S2- species form. A visible spectrophotometer was applied for the analysis of passed H2S gas. Using a PTFE membrane, the optimum flow rate was obtained at 14.71 mL/min, with a mass flux of 0.825 kg/m2.hour, permeability coefficient of 0.696 kg/m2.hour.bar, and percent removal of H2S gas was 88.14%. The optimum flow rate for the SAOB was obtained at a rate of 0.30 mL/min with a mass flux of 0.843 kg/m2.hour and a percent removal of H2S gas of 89.98%. Based on the results obtained on the PVDF membrane, the mass flux produced in the optimization of H2S gas is 0.742 kg/cm2.hour, and the optimization of the SAOB solution is 0.754 kg/cm2.hour. The resulting permeability coefficient value is 0.741 kg/cm2.hour. The results indicate that this study can remove H2S gas at the optimum H2S gas flow rate of 4.76 mL/minute of 94.89% and the optimum SAOB flow rate of 0.3 mL/minute of 95.66%
