The aim of this study was to evaluate the mercury contamination residue in the water, soil, and vegetable fern (Pityrogramma calometanos (L)) The samples were collected from locations in the already closed artisanal gold mining sites. The sampling locations were purposively determined by considering their closeness to the previous gold mining activities sites. The content of mercury was analyzed using flow injection for atomic spectroscopy-atomic absorption spectroscopy. The method used was validated by linearity, Limit of Detection (LoD), Limit of Quantification (LoQ), Relative Standard Deviation (RSD), and recovery. The validation test showed that this method is well linear, sensitive, accurate, and precise with a correlation coefficient, LoD, LoQ, RSD and recovery of 0.9999, 0.0477 µg/L, 0.1447 µg/L, 2.96% and 95-105%, respectively. Herein, it was found that the concentrations of mercury contents in the water samples were below the detectable range. However, a high range of mercury concentration of 0.236-0.328 µg/g was found in soil, with the highest concentration obtained in the sample collected from the riverbank. The fern sample collected near the riverbank contained mercury in all its parts and concentrated in the root (0.408 µg/g in the leaves, 0.276 µg/g-stalks, and 9.994 µg/g-roots). Meanwhile, the absence of mercury contamination was obtained in the leaves and stalks of the fern samples collected far from the riverbank. The roots, however, were detected with mercury contamination with the highest concentration reaching 27.660 µg/g. Despite its disappearance in the water, mercury contamination residue from the former artisanal gold mining activities still could be traced in the soil and heavy metal accumulating plant-P. calometanos (L).

The presence of nitrogen is a special feature of protein compounds because this element is not found in simple fat and carbohydrate compounds. This study aims to determine the protein content in corn flour, cassava flour, and pumpkin flour using the Kjedhal method. Protein analysis by the Kjedhal method is basically divided into three stages, namely: the destruction stage, the distillation stage, and the titration stage. The results showed that the protein content in corn flour was 9.32%, cassava flour was 8.45%, and pumpkin flour was 0.62%. The conclusion of this study is the greatest protein content found in corn flour.

Banyak pembelajar bahasa Jepang yang tidak bisa menulis maupun membaca dikarenakan pembelajar tidak mengingat huruf tersebut secara sempurna. Hal ini dikarenakan sedikitnya waktu belajar huruf dan fokusnya belajar tata bahasa membuat pelajar melupakan untuk belajar huruf. Sehingga pembelajar lebih sering menggunakan huruf romaji dibandingkan dengan huruf kana. Oleh karena itu, diperlukan media yang bisa digunakan siswa secara mandiri. Lembar Kerja Siswa (LKS) merupakan media yang bisa digunakan siswa secara mandiri. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh dari penggunaan Lembar Kerja Siswa (LKS) dalam upaya meningkatkan kemampuan menghapal huruf kana. Penelitian ini menggunakan metode penelitian murni dengan pola “Pretest-Posttest Control Group Design”, yang menggunakan dua kelas yaitu kelas eksperimen ...

The genus Metroxxlen, Sp is a bioplastic material that is easily degraded in the soil. Metroxxlen, Sp has a hierophilic nature which results in its physical properties being low. Bioplastic Starch Genus Metroxxlen, Sp is made by mixing ZnO as a reinforcement, Genus starch Metroxxlen, Sp as a source of natural polymers, with the addition of glycerol as a plasticizer. The results of the spread of ZnO in bioplastics can be seen with SEM. Comparison of ZnO with Genus Metroxxlen starch, Sp 1-3% wt produced a strengthened mechanism characteristic from 0.40 kg/cm 2 to 0.70 kgf / cm 2 ; the change in the extension changed down from 120.4% to 99.00%. For glycerol composition with variations from 1-3% wt, the change in elongation changes to increase from 90.00% to 98.00%, the nature of the mechanism changes to decrease from 0.25 kg/cm 2 to 0.20 kgf / cm 2 .

It is often felled and thrown away. This study was aimed to provide the information the utilized these crops. This research was conducted to determine the ability and characteristics of Rubik stems (Calotropis gigantean) as an addictive substance plasticizer filler, where the rubrik plant was taken at the seaside area of Banda Aceh. Preparation of plasticizers from the filler of this rubric stem was used as an antiseptic and biodegradable plasticizer. The results of FT-IR spectra measurements of the filler plastics of this rubrik plant have a distinct tannin functional group absorption, at 923.850 cm-1 strong buckling numbers were indicated the presence of a potent buckling C-H group due to the presence of the aromatic groups in the tannin compound. For the SEM test, the plasticizer has a porous surface morphology of the outermost layer, this indicates the density of particles smaller than the plasticizer 2 grams of water compared to plasticizer 1 gram of water. The test of biodegradable and Aspergillus Niger fungi on time variations about 10 days were resulted in significant degradation. The rate of degradation with soil was greater than the Aspergillus Niger. Toxicity was used of Escherichia coli bacteria in medium of nutrient agar at 37°C with 48 hours incubation where in plasticizer has antiseptic to Escherichia coli.

The paper determines the behavior of certain segments that attach to its own neighboring words and elaborates the economy of the syllable structure of tokens in a particular language. In Urdu, there are various types of segmental processes in terms of addition or deletion of phonemes that affects to root and alters the entire physical mechanism structure of words. The objectives of this paper are to know the exact economic conditions of syllable structures in the words after the addition or elision of segments in the Urdu language. All the process of conflicts between the segments will manipulate by the help of constraint rankings in Optimality Theory (Prince and Smolensky, 1993). The general purpose of this paper is to reveal the whole criteria of implications of principles of Optimality theory and explore the actual framework of syllables wit...
