Lactalbumin is a major protein found in milk which has great function to human body. It is a component of wheyprotein in milk. Lactalbumin was isolated from cow’s milk of Fries Holdstein breed by centrifugation at high speed9500 rpm and gel filtration chromatography using sephadex G-50 produced Lactalbumin dissolved in Tris buffersolvent. Characterization of Lactalbumin by measuring the UV absorbance spectrum at 240 – 320 nm comparedwith the spectrum of standard Lactalbumin showed maximum peak at the same wavelength, 280 nm. Lactalbumincontent in milk determined by Lowry method was about 0,66 mg/ml in milk or 9,2% of whey.

Abstract: This study aims to determine the difficulties and factors that cause learning difficulties of students on the ion balance and pH of salt solution in class XI MIPA 3 SMAN 1 Kuantan Mudik. This research is a descriptive study with a qualitative case study approach, the population of class XI with a sample size of 35 people in class XI MIPA 3. The data collection technique uses the technique of test questions and questionnaires, and interviews, while the data collection tools use test questions and questionnaire sheets. The results showed that the students had difficulty learning in determining the pH of the salt solution with high and very high categories of learning difficulties. Internal factors that affect students 'learning difficulties are motivational aspects with indicators of learning efforts about ionic balance and pH of salt solution and students' attention to learning these materials with percentage effects of 59.28% and 57.85%, respectively, while external factors which affects learning difficulties in the aspects of teacher teaching 59.86% respectively. The conclusion of this study is that there are learning difficulties of students on the matter of ionic equilibrium and the pH of the salt solution and there are both internal and external factors that affect the learning abilities of students.Key Words: Analysis, Ionic Equilibrium and pH of Saline Solution, Learning Difficulties for

Abstract: This study aims to develop an integrated character education module on valid and practical subject of chemical equilibrium. This development research uses ADDIE model that has 5 stages, Analysis,Design, Development,Implementation and evaluation, but the research only arrived at the Development stage because the purpose of the research was to develop a valid and practical integrated character education module. To produce a valid module, a module validity test was carried out covering four aspects of assessment, namely aspects of content feasibility, linguistic aspects, presentation aspects and graphic aspects. To see the practicality of the module, limited testing was done at SMAN 6 Pekanbaru and SMAN 12 Pekanbaru. The results of the study that have been validated by 3 validators state that the percentage is 93,75%. The results of the test questionnaire were limited to 30 students, 89,58% and the results of the responses from 2 chemistry teachers were 93,5%. Based on the principle of validation and limited testing, the integrated module on character education on the subject of chemical equilibrium was declared valid and practical.Key Words: Modules, Character Education, Chemical Equilibrium
