Abstract

Problem posing learning model was a learning model that assign students to made questions about the material being taught which must then be solved by students either individually or in groups. Reformulate the problem or application problem is one way to make progress in solving the problem. Learn to ask very important in the educational process. Students can not have learned before asked himself, and then answer the question. It is a reflection of the problem posing learning model. Students will got direct experience by doing activities related to the integrated botanical material. This learning model aims to achieve competency in accordance with theme integrated botany in the structure and function of plant tissue is taught. This type of research was a pre-experimental research The method used was the “One Group Pre-test – Post-test” with subjects 26 students class XI Science 1 SMAN 1 Gresik Manyar. The analysis was conducted in descriptive quantitative. Cognitive learning outcomes students, 88.47% of students have completed the classical.

Abstract

Waktu fermentasi berpengaruh terhadap derajat keasaman dan sifat fisik minuman kombucha. Semakin lama proses fermentasi maka diasumsikan pH dari minuman kombucha akan semakin rendah Tujuan utama dari proses pemanasan dalam industri makanan adalah untuk pengawetan. Selama proses pemanasan, aktivitas mikroba akan berkurang, mencegah adanya pertumbuhan dari mikroba serta mencegah terjadinya reaksi kimia yang tidak diinginkan. Penelitian ini merupakan penelitian eksperimental yang bertujuan untuk mengetahui pengaruh lama pemanasan terhadap karakteristik fisik minuman kombucha teh hijau. Penelitian ini menggunakan rancangan acak lengkap bertujuan untuk mengetahui karakteristik fisik yang meliputi nilai pH, warna, aroma dan rasa dari minuman kombucha setelah pemanasan pada waktu pemanasan yang berbeda

Abstract

Ethanol extract of purple sweet potato (Ipomoea batatas (L.)) leaves of Antin-3 variety contains flavonoids and polyphenols which can be used as a source of acne anti-bacterial because it can inhibit the growth of Staphylococcus aureus. This study aims to obtain data on physical characteristics, acceptability and stability of anti-acne mask formulation of 70% ethanol extract of Antin-3 leaves. The research method used were characteristic, acceptability and stability test. There were 4 types of samples tested, namely base, Antin-3 extract 5%: 10% and 20% (B: F1: F2: F3). The organoleptic results showed that the higher concentration of extract, the darker color of mask and the stronger of extract smell and the softer of consistency. The pH values ​​(B: F1:F2: F3) were respectively 6.46; 5.78; 5.75; 5.46. The value of adhesion (B: F1: F2: F3) were respectively 1.1; 1.46; 2.17 and 4.53 seconds. The value of spreading capacity (B: F1: F2: F3) were respectively 3.89; 4.15; 4.36 and 3.45 cm. The results of the acceptability test showed that F2 was the easiest formula to spread, clean and softest sensation on the skin. The results of the mechanical and cycling test showed that the four samples had not undergo phase separation. Anti-acne mask with 70% ethanol extract of Antin-3 leaves by 10% met the physical characteristics, acceptability and stability.

Abstract

The purpose of this study was to determine the characteristics of Auricularia extract which was extracted using 96% ethanol (sample E) and methanol (sample M). Auricularia was powdered before extraction. Extraction of mushrooms was carried out using the maceration method for three days. The solvents used for extraction were 96% ethanol and methanol. The extract that has been obtained is calculated by weight yield, tested for solubility, pH, and organoleptic tests. The yield weight of sample E was 1.47% higher than sample M, which was 1.22%. In the solubility test, sample E dissolved in water had a higher solubility of 60% compared to 96% ethanol, which was 55%, on the other hand, sample M dissolved in ethanol 96% had a higher solubility of 55% compared to 40% in water. Samples E and M dissolved in water had the same pH of 5, as well as those dissolved in 96% ethanol, which was 6. The organoleptic test on samples E and M had similarities in smell and shape, the difference was the color. The conclusion is samples E and M have almost the same characteristics.

Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan bakteri indigenus dalam mendekolorisasi limbah cair gula rafinasi dalam berbagai pH.Penelitian ini merupakan penelitian experimental dengan rancangan acak lengkap dengan 3 kali pengulangan. Data yang diperoleh dari penelitian ini berupa: 1) jumlah bakteri indigenus pendekolorisasi limbah; 2) pengukuran nilai dekolorisasi; 3) nilai Log TPC; 4) identifikasi tiga bakteri dengan nilai dekolorisasi tertinggi. Hasil isolasi dan uji dekolorisasi menunjukkan bahwa terdapat sembilan bakteri indigenus yang mampu mendekolorisasi zat warna melanoidin. Sembilan bakteri indigenus tersebut yang memiliki kemampuan dekolorisasi terbaik secara berturut-turut yaitu DC2, DC4 dan DC1 dengan nilai dekolorisasi masing yaitu, 29,59±0,061, 23,68±0,055, dan 22,85±0,038. Adapun nilai Log TPC berkisar antara 9,2 – 4,5. Sedangkan pH terbaik untuk dekolorisasi ketiga bakteri tersebut adalah 11. Hasil identifikasi menunjukkan bahwa ketiga bakteri terbaik tersebut adalah Bacillus sp dan Pseudomona diminuta. Berdasarkan hasil tersebut dapat disimpulkan bahwa untuk menguraikan melanoidin atau dekolorisasi limbah cair gula rafinasi dapat menggunakan bakteri indigenus yg bias diisolasi dari limbah itu sendiri.
