The Miana Coleus atropurpereus plant is a unique plant because it has so many varieties. The differences in these varieties can be seen from the very diverse differences in leaf color. Several studies have known about the active antimicrobial compounds of Coleus atropurpereus miana leaves, namely in the form of flavonoids, saponins, steroids, tannins, essential oils, eugenol, polyphenolic compounds, alkaloids, ethyl salicylate, calcium oxalate, rosmarinic acid compounds. In this study, Escherichia coli and Staphylococcus aureus bacteria were used using thick extracts that had been macerated using 96% alcohol. in this study it showed 8 mm at a concentration of 50%, at a concentration of 25% it showed a clear zone of 7 mm and at a concentration of 12.5% ​​it showed 6 mm. It can be concluded that the extract of Coleus atropurpereus miana leaves is weakly toxic to E. coli and not toxic to S. aureus bacteria..  

Papaya Carica papaya L. is a fruit commodity that has many functions and benefits as cooking, sweets, medicine, snacks. Secondary metabolite compounds found in Carica papaya L. papaya are flavonoids, polyphenols, quinones and tannins. It is known that falvonoid compounds can have antibacterial properties. In this research, it is hoped that papaya leaf stalk extract can act as an antimicrobial so that it can be used as first aid for diseases caused by E. coli bacteria.  This research used ingredients from 500 grams of papaya leaf stalk extract which had been macerated using 96% ethanol, to produce a thick extract. The thick extract was tested on NA growth media using E. coli bacteria. In this study, the clear zone produced at a concentration of 50% was 7 mm, at a concentration of 25% it produced a clear zone of 6 mm and at a concentration of 12.5%  it did not produce a clear zone.

Plants have several ways to protect themselves from bacteria, one of which is by producing compounds that are toxic or repellent to bacteria. Compounds produced by plants are known as secondary metabolite compounds which originate from secondary metabolic processes. Several secondary metabolite compounds such as flavonoids, alkaloids, saponins, tannins, steroids and terpenoids are currently widely used as antibacterials. One of the plants that has the potential to be developed as a herbal medicine is kaffir lime leaves. Citrus hystrix is ​​the part of the plant most often used by the public. Both for cooking and traditional medicine purposes. In this research, it is hoped that lime peel extract can act as an antibacterial for Escherichia coli and staphylococcus aereus, so that it can be used as a herbal plant for diseases caused by these two bacteria. In the research, the concentrations used for each test bacteria were 50%; 25%; 12.5%. in observing S. aureus bacteria 1x24 hours with a concentration of 50%, the size of the inhibitory zone was 16 mm, the 25% concentration was 11 mm and the 12.5% ​​concentration was 9 mm. Meanwhile, E. Coli bacteria did not show any reaction to the heruk peel extract.

Minyak kelapa murni atau lebih dikenal dengan Virgin Coconut Oil (VCO) merupakan modifikasi proses pembuatan minyak kelapa sehingga dihasilkan produk dengan kadar air dan kadar asam lemak bebas yang rendah, berwarna bening, berbau harum, serta mempunyai daya simpan yang cukup lama yaitu lebih dari 12 bulan. Pembuatan VCO dengan cara fermentasi kelapa akan mendapatkan bakteri asam laktat dan bersifat bakteriosin pada setiap lapisannya. Bakteri asam laktat yang didapatkan adalah sebagai probiotik yang menghasilkan berbagai macam produk fermentasi seperti etanol, karbondioksida, asam asetat, dan peroksida. Beberapa Studi menunjjukkan bahwa VCO dapat meningkatkan system kekebalan tubuh, dan mampu untuk mencegah terjadinya infeksi. Sehingga pada pengabdian Masyarakat yang dilakukan di SMKN 8 batam Sei pelunggut, kacamatan sangulung kota batam, diharapkan dapat memanfaatkan kelapa untuk pembuatan VCO. Melalui kegiatan ini telah dihasilkan suatu cara atau metode yang mudah dan sederhana dalam pembuatan VCO dan para siswa/siswi SMKN 8 Batam yang mengikuti pelatihan ini mendapatkan pengetahuan yang bermanfaat dan memiliki kemampuan untuk membuat dan mengembangkan produk VCO ini ketika stock kelapa melimpah dan dapat dilanjutkan menjadi usaha skala rumah tangga serta berpotensi untuk dikembangkan menjadi usaha yang lebih besar dan bisa dipasarkan ke pasar modern
