Abstract

This study aims to provide information about the diversity of Charophyta microalgae in the Mesat river, Lubuklinggau City. This type of research is survey research so that the data collection in this study was carried out by observation. This research was conducted in February-April 2020. The study was conducted in the Mesat River, samples of microalgae were taken from 3 different stations following the flow of the river. Based on the results of the research conducted, the Charophyta microalgae species found in the Mesat River, Lubuklinggau City, consisted of: 1 Class, 2 Orders, 3 Families, 10 Genus, 20 Species. Based on the analysis results, the diversity value at station 1 is 1.27, station 2 is 0.98 and station 3 is 1.04. while the dominance value at station 1 is 0.019, station 2 is 0.0008 and station 3 is 0.006. The uniformity value at station 1 is 0.42, station 2 is 0.32, and station 3 is 0.34. Measurement of abiotic factors in the Mesat river consists of: temperature, dissolved oxygen, acidity and brightness. The temperature at station 1 is 27.20C, station 2 is 26.56 0C and station 3 is 26.870C. The dissolved oxygen content at station 1 is 45.94 mg/L, station 2 is 42.31 mg/L, and station 3 is 44.63 mg/L. while the acidity at station 1 is 6.70, station 2 is 6.63 and station 3 is 6.6. Then the brightness of the Mesat river at station 1 is 16.33cm, station 2 is 22 cm and station 3 is 18.63cm. Microalgae diversity of the Charophyta division in the Mesat River, Lubuklinggau City in the Medium Category.

Abstract

Objective: The purpose of this study was to predict the kinship of ornamental pigeons based on blood proteins.Methods: The research method used is exploratory descriptive with a laboratory observation-based approach. Research procedures include: Blood Sampling, Blood Protein Isolation, Purification, Measurement of concentration with a nanodrop spectrophotometer and Electrophoresis. Data analysis includes: Protein Band Profile and Determination of Protein Molecular Weight with RF formula and Relationship with MVSP version 3.22 program.Results: The protein profile in the plasma of ornamental pigeons is different from one type of pigeon to another. some of the protein appears in the ornamental pigeon species but does not appear in other breeds. Likewise with the target protein to be analyzed, some are expressed and some are not expressed in ornamental pigeons. Results based on the analysis of protein profiles and dendograms of the four specific proteins (hemoglobin, transferrin, posttransferrin, and immunoglobulin) contained in erythrocytes and blood plasma, it can be seen that there are two clusters. Cluster 1 is occupied by varieties of ornamental pigeons Moven and cluster 2 is occupied by varieties of ornamental pigeons Lahore, American fantail, Vienna, Indian Fantail, King, Capucine, Gondok and Modena.Conclusions: The results of the ornamental pigeon kinship prediction based on blood protein showed that each variety had different kinship relationships. King, Capucine, Gondok and Modena pigeons have the closest relationship, and Moven pigeons have the most distant relationship from the researched ornamental pigeons.

Abstract

Dysentery is an acute diarrheal disease with chronic symptoms, including diarrhea, fever, nausea, abdominal pain, and vomiting. Stool is liquid and mixed with blood that passes through the large intestine very quickly because bacteria have penetrated the large intestine caused by the bacterium Shigella dysentriae. Sungkai plant (Paronema canescens Jack) is one of the plants used as traditional medicine and contains antibacterial compounds consisting of phenolic compounds and their derivatives. This study aims to determine the effect of antibacterial activity of the extract of Sungkai Leaf Starch (Paronema canescens Jack) on the Inhibitory Zone of Shigella dysentriae. The research method is a laboratory experimental method, this type of research is a quantitative research, and the design used in the study is a Post Test Only Control Design. The results showed that sungkai leaf extract (Peronema canescens Jack) with concentrations of 65 grams, 75 grams, 85 grams, and 95 grams had different inhibitory effects on Shigella dysentriae. The conclusion from the non-parametric statistical test results using the Kruskal Wallis test, it was found that sig. < that is 0.001 < 0.05 which indicates that the resulting data has a significant difference.

Abstract

Berbagai keterampilan yang perlu diajarkan pada siswa agar siap menghadapi tantangan hidup abad ke-21 mencakup berpikir kritis dan memecahkan masalah; berkomunikasi; kreativitas dan inovasi; serta kolaborasi. Keterampilan lain seperti entrepreneurship skill juga menjadi poin penting dalam pembelajaran abad ke-21. Pembelajaran bioentrepreneurship menjadi solusi untuk memperbaiki hasil belajar dan mengajarkan keterampilan berwirausaha pada siswa khususnya siswa kelas XII IPA. Penelitian ini merupakan Penelitian Tindakan Kelas yang memuat dua siklus, dengan masing-masing tahapan berupa planning, implementing, observing dan reflecting. Tujuan penelitian ini untuk meningkatkan hasil belajar biologi siswa. Adapun subyek penelitian ini adalah siswa kelas XII IPA MASSKH Jombang dengan jumlah 22 siswa. Instrumen penelitian ini berupa lembar tes soal pilihan ganda dan lembar observasi. Analisis data dilakukan secara deskriptif kualitatif. Dari hasil penelitian dapat diketahui bahwa terdapat peningkatan pada hasil belajar siswa dari siklus I sebesar 66,3 menjadi 74,5 pada siklus II. Dengan demikian dapat disimpulkan bahwa pembelajaran bioentrepreneurship mampu meningkatkan hasil belajar siswa.
