“…The discussion in this study includes the effect of the hand soap making practice using pineapple skin extract (Ananas comosus L. Merr) on students' learning interest. Pineapple skin extract (Ananas comosus L. Merr) contains natural compounds namely tannins which function to regenerate the skin, saponin which functions to add foam to soap and flavonoids that function as an anti-bacterial which is used as an additional material in the manufacture of hand soap (Manaroinsong, 2015;Situmeang et al 2019;Salasa et al 2019;Daely et al 2019;Yusliana et al 2019).…”

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.

هههTyphoid fever is still a severe issue in the world. The pharmacological therapy used for typhoid fever was chloramphenicol antibiotics. However, chloramphenicol resistance to Salmonella typhi is common, so finding alternative antibacterial drugs for typhoid fever is necessary. Gambir Extract was a natural ingredient often used in non-pharmacological alternative therapies. It contained secondary metabolites such as alkaloids, flavonoids, tannins, and saponins which are suspected to be antibacterial. This study aimed to identify the Minimum Inhibitory Concentration and the Minimum Bactericidal Concentration values of Gambir Extract against Salmonella typhi. The antibacterial activity of the Gambir Extract against Salmonella typhi was screened using the well diffusion method. The MIC and MBC of the Gambir Extract were determined using the dilution method. Data were analyzed using the Kruskal-Wallis test and the Mann-Whitney test. The inhibition zone of the antibacterial activity of the Gambir Extract against Salmonella typhi was 19.22 mm and had a MIC value of 50% (0.5 g/ml). The statistical analysis results of the Kruskal-Wallis and the Mann-Whitney test obtained significance values of 0.007 and 0.025. Therefore, Gambir Extract cannot kill Salmonella typhi. Gambir Extract has antibacterial activity against Salmonella typhi with a MIC value of 0.5g/ml. Keywords: Antibacterial, Gambir, Minimum Bactericidal Concentration (MBC), Minimum Inhibitory Concentration (MIC)

Abstrak: Permen jeli disebut juga dengan permen lunak merupakan jenis makanan selingan berbentuk padat, dibuat dari gula atau campuran gula dengan pemanis. Nanas merupakan salah satu buah yang memiliki aktivitas sebagai pembunuh bakteri. Bagian nanas seperti daging dan kulitnya mempunyai kandungan klor, iodium, fenol dan enzim bromealin dalam kulit buah nanas Nama kegiatan pengabdian masyarakat ini adalah peningkatan keterampilan siswa tentang pemanfaatan kulit nanas menjadi permen jeli di SMK Muhammadiyah Lebaksiu. Tujuan dari kegiatan ini adalah meningkatkan pengetahuan dan pemahaman mengenai kemanfaatan permen jeli ekstrak kulit nanas untuk siswa siswi SMK. Pengabdian masyarakat ini melibatkan 40 siswa siswi SMK. Metode yang digunakan adalah seminar dan praktek. Instrumen yang digunakan lembar pre-test dan post-test. Kemudian dianalisis menggunakan distribusi frekuensi untuk data demografi dan grafik untuk nilai pre-test dan post-test. Dari hasil analisis pre-test dan post-test menunjukkan peningkatan keterampilan siswa siswi sebesar 30%. Hal ini dikarenakan SMK Muhammadiyah Lebaksiu menerapkan mata pelajaran terkait bahan alam serta mulai dikembangkannya Green House untuk budidaya TOGA. Peningkatan keterampilan ini signifikan yaitu 75%.Abstract: Jelly candy also known as soft candy, is a type of solid snack made from sugar or a mixture of sugar and sweeteners. Pineapple is a fruit that has activity as a bacteria killer. Parts of pineapple such as flesh and skin contain chlorine, iodine, phenol and bromealin enzymes in pineapple skin. The purpose of this activity is to increase knowledge and understanding of the benefits of pineapple peel extract jelly candy for vocational students. This community service involved 40 SMK students. The method used is seminar and practice. The instruments used were pre-test and post-test sheets. Then analyzed using frequency distribution for demographic data and graphs for pre-test and post-test scores. From the results of the pre-test and post-test analysis showed an increase in the skills of students by 30%. This is because SMK Muhammadiyah Lebaksiu applies subjects related to natural materials and has begun to develop a Green House for TOGA cultivation. This skill increase is significant at 75%.
