ABSTRAKIlmu Pengetahuan Alam (IPA) berkaitan dengan cara mencari tahu tentang alam secara sistematis, sehingga IPA bukan hanya penguasaan kumpulan pengetahuan yang berupa fakta-fakta, konsepkonsep,atau prinsip-prinsip saja. Proses pembelajarannya menekanzkan pada pemberianpengalaman langsung untuk mengembangkan kompetensi agar menjelajahi dan memahami alamsekitar secara ilmiah. Pendidikan IPA diarahkan untuk inkuiri dan berbuat sehingga dapatmembantu peserta didik untuk memperoleh pemahaman yang lebih mendalam tentang alamsekitar. Sesuai dengan teori pembelajaran konstruktivisme oleh Piaiget.

Learning by practicum method is a way of delivering learning material by providing opportunities to the students to practicein order to make the students engage in planned and active learning experiences so that students' interest grows on chemistry subject. The population in this study were the students of XI class at YAPSI Senior High School in Medan. The sampling technique is done by using the Quota sampling technique. The instruments were the student’s interests in questionnaire and student activeness observation sheet. The requirements test is in the form of normality test and homogeneity test with the value of Lcount = 0.663 initial interests data and Lcount = 0.172 final interests data which means the data is normally distributed. In the homogeneity test Fcount = 0.233 initial interests data and Fcount = 0.449 final interests data with homogeneous results. The data analysis technique was done by using the hypothesis t test and N-gain test. The results showed that the hand soap making practice with the addition of pineapple extract (Ananas comosus L.. Merr) had an influence on students’ learning interest with N-gain of 7.6 in experimental class data and N-gain of 5.4 in control class data and from the t hypothesis test obtained Tcount> Ttable which Tcount = 6.90 and Ttable at level 0.05 is 2.01 so Ho is accepted, which means that there was an influence of the handsoap making practice with the addition of pineapple skin extract (Ananas comosus L. Merr) on student interests in learning.Keywords: Colloid; hand soap making practice; interests

Abstract. This study was aimed to obtain innovative teaching material based on multimedia to learning the pH solution which can improve learning outcomes and student motivation. The population of this research was all of the even semester students of the State University of Medan (UNIMED). The research sample was taken by using the purposive random samplingwith ± 76 students as the samples who were studying General Chemistry II course at the UNIMED consisting of two classes, the experimental class and the control class. The experiment class used innovative teaching materials that have been developed while the control class used the chemistry student handbook. Five lecturers from the UNIMED and the North Sumatera Islamic University (UISU) were appointed as the validators of the developed innovative teaching materials. The results showed that: (1) the chemistry books that were analyzed gave an average 49,67% which is considered adequate and do not need any revision.
