The purpose of this research was to describe the life skills of students in learning chemistry and reveals the connections between life skills. The methods used in this research is descriptive research. The subject of research as much as 144 students of class XI in one of senior high school in the city of Padang. The selection of samples was conducted with stratified random sampling technique that divides students into 3 groups based on the level of their intelligence (IQ). Research data taken with observation, interview guidelines and tests of the student’s life skills. The results showed that the personal skills for students classified as well. The social skills of students is very good, students are able to manage their emotions very well, able to communicate well, has good interpersonal relationships, and understanding the other person very well. Student's academic prowess is quite good the ability of critical thinking, creative thinking, problem solving, and decision making students are on a category is good enough. The connection between life skills showed that a) there is a weak relationship between personal proficiency students with social skills among students with the values of the coefficients of correlation 0.33, b) there is a very weak relationship between students personal skills with the academic skills of students with the value of the correlation coefficient 0,004, and c) there is a very weak relationship between social skills among students with the academic skills of students with the value of the correlation coefficient 0,062.

Abstract- Very rapid development of the industry has led to increased levels of heavy metals in the environment. Heavy metals are the main group of inorganic pollutants that can contaminate wastewater in the environment. One of them is copper metal (Cu). Copper metal has a reddish brown color. This metal is very poisonous, and in high concentrations it can interfere with human health, such as damaging the respiratory system, mental disorders in children, cancer, death, and so on. This can be anticipated in various ways, one of which is the Solidification Method. The principle of the solidification method is to bind compounds in hazardous waste into insoluble / solid form and trap the waste in solids. The paramenter analysis used is the TCLP (Toxicty Characteristic Leaching Out Procedure) test. From the research data, it was found that the highest concentration of oily sludge was 0.19 mg / L and the lowest was 0.15 mg / L. In used oil waste, the highest concentration is 1.6 mg / L. From the solidification results of oily sludge and used oil waste, it can be concluded that the value of oily sludge waste is smaller than used The oil waste, and it can still be said to be safe to dispose of into the environment. The higher the cement solidification in the sample test, the higher the Cu content in the sample.

The increase in industrialization is in line with the increase in pollution of heavy metals that pollute the environment. Such waste needs to be managed properly for laws that are harmful to human health and the environment. Calcium oxide (CaO) is an exceptionally important industrial compound, which is used as toxic-waste remediation agent. Thermal decomposition method has some advantages such as simple process, low cost, ease of obtaining high purity product, etc. Characterization with the FTIR instrument showed the strong band at 3643 cm_1 corresponds to the O-H bonds from the remaining hydroxide. Bands at 1417 cm-1 and 866 cm-1 correspond to the C-O bond. The wide and strong bands at around 427 cm-1 and 553 cm-1 correspond to the Ca-O bonds. Characterization with the FTIR instrument showed the peaks were higher in intensity and narrower in spectral width, indicating that the products were of good crystallinity.

Industrial wastes generated from various industrialization activities usually contain a variety of toxic heavy metals. The resulting heavy metal is very toxic and is detrimental to the health of living things. Various technologies have been developed to deal with heavy metal waste. One of them is the method of remediation of solidification / stabilization. In this review, what will be discussed is the method of thermal solidification / stabilization. Thermal technology in the method of solidification / stabilization is a very useful method with low cost and simple methods. Stabilized metal waste can be obtained as building materials such as bricks. Vitrification or thermal methods are thermal waste treatments that convert waste into glass or crystalline materials. Most of these methods operate at 1200 ° C. In the study (I.B. Singh, 2006) solidification / thermal stabilization using fly ash binder and clay. In his research using thermal combustion temperatures of 850 ° C, 900 ° C and 950 ° C. Thermal treatment with fly ash and clay binder can reduce contaminants to the maximum.

Analisis XRD dan Leaching Out dari Solidifikasi/Stabilisasi Ion Logam Cr(VI) Menggunakan Semen Shinta Bella; Jon Efendi

Cr (VI) metal waste becomes one of the heavy metal wastes which is very difficult to overcome. For this reason, the Cr (VI) waste processor uses a stabilization / solidification method to reduce the concentration of Cr (VI) metal ions in the environment by using cement as a binder. The testing setting time for cement is that by increasing the Cr (VI) concentration, the longer it takes for the cement hardening process. This is in line with the results of the compressive strength test, where the results for concentrations of 0.5%, 2%, and 5% were 32, 26, and 23 MPa, respectively. whereas according to the US EPA, the minimum compressive strength test is 0.3 MPa. TCLP test for 96 hours for this method is that the higher the concentration, the higher the Cr (VI) leaching in cement.

Background: Invagination is an acute condition in the pediatric abdomen that results in obstruction and constriction of blood vessels (strangulation) in the proximal intestinal mesenterium trapped in the distal intestine, allowing necrosis of surrounding tissue. Intestinal necrosis and perforation in children are causes of abdominal emergencies that require immediate surgery. In supporting examinations, neutrophil, lymphocyte, and biomarker combination ratios have been used for early detection of systemic inflammatory markers. The threshold value of several biomarkers should be investigated to assess the occurrence of strangulation in the pre-operative period in invaginated patients. This study aimed to determine the relationship between neutrophil-lymphocyte ratio and intestinal viability in pediatric patients with invagination. Methods: This study used retrospective analytic data collection from medical records of invagination patients at Dr. M. Djamil General Hospital Padang for the period January 1, 2020, to December 31, 2022. Results: The majority of subjects were male (53.8%) at the age of ≤ 1 year, with as many as 87.2% having a diagnosis of operative invagination (76.9%) and 56.4% having intestinal viability. The mean neutrophil, lymphocyte, and NLR values were 62.15±17.68, 19.03±8.97, and 3.74±1.55, respectively. The pathological NLR status was found to be 59%. The p-value for the association of diagnosis with intestinal viability was 0.002. The p-value for the relationship between NLR and intestinal viability was 0.001, and the r-calculated was -0.528. Conclusion: There is a significant relationship between NLR value and disease diagnosis on intestinal viability.
