In the research, resulted copper atom is measured on heated open absorption cell. The copper hydride was formed by reduction of Copper (II) with hypophosporus acid 4% at temperature 80 o C. Sodium lauryl sulphate 0.01 M was used as a misel production to carry out copper hydride to absorption cell of hot vapour atomic absorption spectrometry (HV-AAS). The optimum condition of experiment were; 0.5 ml of H3PO2 4%, 805 o C of reaction temperature, 0.5 mL of sodium lauryl sulfat 0, 01 M, 605 second of formation time, and 15.35 cm long of glass a pipe. Argon or air for blowing was conducted at the base of flask reaction with 324.7 nm wave length measurement. The duration of measurement was 35 seconds. Regression equation of standard copper absorbance 5 to 30 mg/L was Y = 0, 026 + 0, 0091x. By using the equation, the characteristics of analytical procedure were found: 3.65 mg/L detection limit, 0.18 mg/L sensitivity. The accuration of the procedure is 1.41%, its precision 10.59%, repeatability is 3.79 at 10 mg/L concentration of solution and average value of confidence interval 95% was 9.86 0.8 mg/L or at range 9.1 to 10.7 mg/L. Linearity range standard of concentration is 5 to 25 mg/L (absorbance 0.088 to 0.258). The analysis procedure characteristics obtained with HV-AAS is less effective than flame atomic absorption spectrometry (FAAS) as its detection limit is 0.004 mg/L and its sensitivity is 0.03 mg/L.

This study involved expert review in synthesizing the modified conceptual procedure model of PBL with FC. The observation sheet is used for the conceptualization analysis of the modification of the PBL model with FC which aims to obtain input and expert opinion on the subject matter developed through the application of the Delphi technique to improve mathematical argumentation skills. From the results of modifying the pbl model by integrating the flipped classroom, we get a new model called the Problem Based Learning-Flipped Classroom Model (PBL-FC Model). The PBL-FC model is designed in learning to enable students to construct meanings from spoken, written and graphic messages through interpreting, exemplifying, classifying, summarizing, concluding, comparing and explaining. Data analysis of argumentation skills was carried out using t-test. Based on the significance value of 0.000 ≤ 0.05 by using the t-test, there is an increase in mathematical argumentation skills in the application of the PBL-FC Model. This research recommendation is expected to be a theoretical basis for researchers and educators in measuring other skills.

Bentonite was activated by HCl, H 3 PO 4 , NaCl, ZnCl 2 , NaOH and KOH use different concentration such as 0.5, 1.0 and 1.5M. Activated bentonite has been characterized by x-ray diffraction, scanning electron microscope with energy dispersive spectroscopy and atomic absorption spectrometry. Bentonite characterization showed that bentonite contains kaolinite, montmorillonite, quartz and cristobalite. Activated bentonite has bigger pores than natural bentonite. Atomic absorption spectrometry showed that H 3

Rubber fruit shell has dried by sunshine for three days and crushed using crusher until the material becomes ash, ash has sifted in 80 and 120 mesh. Ash burned in 400°C and 500°C, ash has activated use acid activator (H3PO4) 10% for 24 hours, and then carbon cleaned by aquadest till the pH is seven. Then, carbon has dried in oven for 3 hours with temperature 110°C. Specification test using gravimetric method has used to find water concentration and ash content in rubber fruit shell. Titration test used to find adsorption of iodine (mg/g), spectrophotometry UV-VIS used to find adsorption of blue methylene with a wavelength of 560.50 nm, blue methylene has used too for finding a surface area. Freundlich and Langmuir isotherm model has used to find best isotherm model. The isotherm model suitable for adsorption this time is the Freundlich isotherm model because it has a linear line equation that is y = 0.4784x + 3.3971 with the correlation coefficient (r) is 0.9922

Multiple efforts have been made but have not reached the small to medium-scale laundry industry; this happens because of the high cost of technology. In this paper, the sorption process by rubber fruit shells successfully reduced the pollutants parameter from greywater. This research has succeeded in creating an adsorbent with raw rubber fruit shell waste; studies on manufacturing techniques, adsorbent characteristics, ability to reduce phosphate content, and adsorption isotherm models are well described. This study also promotes the utilization of rubber shell waste that has not been utilized properly. Adsorbents derived from rubber fruit shells reduced phosphate levels by up to 98% by adding 0.5 g of adsorbent to 100 mg/L of phosphate for 60 minutes. The appropriate adsorption isotherm model in this study is the Freundlich isotherm model.

This type of research is an experiment with a completely randomised design consisting of 4 treatments with 5 replications, so that 20 experimental units are obtained. The variance test with a 95% significance level was used to analyse the research data, followed by the least significant difference test. The results showed that the haematological profile after administration of pineapple extract had a significant effect on increasing the platelet count of male wistar strain white rats and had no significant effect on the number of erythrocytes, leukocytes, hematocrit, or hemoglobin. The results of this study can be used as input in the utilization of the potential of pineapple extract as an anti-inflammatory.

In Jambi Province, people living in Gambut Jaya Village always experience difficulties and clean water crisis, especially during the dry season. Sources of peat water are quite abundant and abundant, but cannot be used as a source of clean water, because the quality of peat water is very poor and unfit for consumption. One solution that can be done is to implement peat water treatment technology, namely CCBN5651 Technology. The activity was carried out in the community settlement of Gambut Jaya Village, approximately 90 km from the Jambi University Campus. The form of activity is an initial analysis of the condition of peat water to be treated (physical, chemical and biological parameters), designing two peat water treatment units for two community groups. Then install the installation of piping tools, procure and manufacture CCBN5651 powder, then carry out peat water treatment, test the quality of clean water produced and finally train and make SOPs for the application of CCBN5651 Appropriate Technology. The results of the activity are very beneficial for the community, two units of peat water treatment installations (PWT CCBN5651) have been built in the location of hamlet 1 and hamlet 2, Gambut Jaya Village, Sungai Gelam District, Muara Jambi Regency. Each installation was built with a size of 4.8 m x 2.5 m (location 1) and a size of 5 m x 2.5 m (site 2). Each treatment unit can produce 20,000 liters of clean water for each treatment, one day it can be processed 3-4 times. Thus the clean water needs of rural communities can be met.
