Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi senyawa metabolit sekunder ekstrak etil asetat dari daun sambiloto. Isolasi tersebut dilakukan melalui tahap maserasi, fraksinasi, dan kromatografi. Identifikasi ekstrak tersebut dan isolatnya dilakukan dengan cara uji fitokimia, spektrofotometer-UV Vis, dan IR. Daun sambiloto kering sebanyak 633 gram dimaserasi dengan metanol selama 3×24 jam, dan diperoleh ekstrak kental metanol setelah melalui proses evaporasi. Ekstrak tersebut difraksinasi berturut-turut dengan n-heksana dan etil asetat untuk menghasilkan ekstrak kental etil asetat sebanyak 21,99 gram. Kemudian, ekstrak kental etil asetat dipisahkan dengan kromatografi kolom dan diuji kemurniannya dengan KLT dan diperoleh isolat murni yang berupa kristal putih dengan berat 126,3 mg. Hasil uji fitokimia ekstrak etil asetat menunjukkan bahwa daun sambiloto mengandung flavanoid dan triterpenoid. Sementara, isolat murni yang dihasilkan adalah senyawa triterpenoid.

This study aims to determine the iron content of water wells in Dulalowo and Heledulaa, Gorontalo City. Ten well water samples were taken randomly from five different wells in each district. Water samples at each well consist of top, middle, and bottom water. Determination of iron level using Atomic Absorption Spectrophotometer (AAS) at a wavelength of 248.33 nm. The results showed that the iron concentration of well water in Dulalowo was 0.030 (D1), 0.265 (D2), 0.224 (D3), 0.158 (D4), 0.149 ppm (D5). Meanwhile, iron levels in Heledulaa were 0.100 (H1), 0.039 (H2), 0.159 (H3), 0.198 (H4), and 0.235 ppm (H5). These results prove that the Fe content in the well water in the two districts is still fulfil the drinking water standard which is a maximum of 0.3 mg/L iron.

Chemistry learning has so far emphasized macroscopic and symbolic aspects as a result of misconceptions and students' low understanding of chemistry. This study aims to determine the influence of science process skill through guided inquiry model on student learning outcomes on acidic-basicsolution topic. The type of research is experimental research with Posttest-Only Control Design. Sampling was done by using Purposive Sampling technique. The sample of research for the experimental class and control class were 31 students, respectively. Data collection using objective test as an instrument that contains test about acidic acid material. Data analysis technique used to test the research hypothesis is t-test. Based on the statistical results obtained the average value of post-test experimental class is 58.55 while for the control class the average post-test value is 39.68. Result of data analysis for learning result show that in significant level 0,05 obtained tcount> t table (6,22> 1,671), then H0 rejected or accepted H1. Thus it can be concluded that there is the influence of process skills of science through guided inquiry model on student learning outcomes on acidic acid solution materials.The positive effects are also discussed in this study.

The purpose of research was to determine the problem solving skill of basic chemical laws at tenth-grade senior high school of through the application of guided inquiry learning models. The ability is known through a three tier multiple choice diagnostic test. This research was an experimental quasi with pretest-posttest control group design. The sample consisted of 107 students consisting of 56 experimental class and 51 control class. Based on the results of the calculation of the F test that F count> F table (10.72> 3.93) with α = 0.05. This means that there was an influence of the application of the guided inquiry learning model to students' ability to solve problems in the basic laws of chemistry. 70.71% of students in the experimental class can understand the problem, plan the solution, carry out the solution, and re-examine the results of the problem solving. Meanwhile, control class students were unable to solve very high problems, namely 24.5% students..
