Abstract

Endophytic fungi is a symbiotic microorganism which live inside plant tissues and not harm to their host. Several genera from endophytic fungi known to produce secondary metabolite compounds like antibiotics, anticancer, antifungal, antiviral and antimalarial. This study aimed to investigate antibacterial activity of endophytic fungi from senduduk (Melastoma malabathricum L.) against Escherichia coli and Staphylococcus aureus. Based on the test result, 11 isolates endophytic fungi from senduduk were known to have antibacterial activities. Isolate code 23 have ability to inhibit the growth of E.coli with diameters zone of inhibition is 22 mm and eight isolate endophytic fungi have ability to inhibit the growth of S.aureus (showed by inhibition zone).

Abstract

Escherichia coli is a bacteria that inhabitant in the cattle or human intestine. Raw beef sold in the traditional markets is easily to contaminated by E. coli. It’s because the markets is one of the vulnerable and the risk is high enough against contamination. The goal of this research is to detect E. coli contamination in the fresh raw beef at several markets in Pekanbaru. This research used 100 gr fresh raw beef purchased from the six traditional markets in Pekanbaru. The study begins with a Most probable Number (MPN) test, than isolation and identification of the media ECB and L-EMB, initially with IMViC test (Indol, Methyl Red, Voges Praskauer and Citrate). Results of MPN test showed that all raw beef were contaminated E.coli with MPN varying value.

Abstract

Endophytic fungi are microorganisms living in healthy tissue of their host plants without causing disease. Endophytic fungi live in every plant, including Vetiveria zizanioides L. medicinal plant intracellulary and/or intercellulary. This plant was screened pharmacologically for antibacterial, antifungal, anticataleptic, analgesic and anti-inflammatory, rheumatism, anti oxidant and anti arthritic activity. This research aimed to isolation endophytic fungi from V. zizanioides L. and to screening their antimicrobial potency against microflora Escherichia coli, Staphylococcus aureus, and Candida albicans. Endophytic fungi isolation from V. zizanioides L. was done by surface sterilization method. A total of 33 isolates were recovered from 88 leaves and 88 root segments. Based on antimicrobial activitytest, most of the fungal extracts showed in vitro inhibition of microbes growth.

Abstract

Tujuan penelitian ini untuk menguji aktivitas antibakteri isolat aktinomisetes yang telah diisolasi dari tanah Hutan Larangan Adat Ghimbo Potai, Kabupaten Kampar, Provinsi Riau. Penelitian dilakukan pada bulan April sampai dengan Juli tahun 2016. Uji aktivitas dilakukan menggunakan metode difusi agar terhadap 2 bakteri uji yaitu Escherichia coli and Staphylococcus aureus. Hasil uji aktivitas isolat aktinomisetes NA-1 dan NA-2 menunjukkan bahwa hanya isolat NA-1 yang memiliki kemampuan menghambat pertumbuhan bakteri S. aureus dengan diameter zona penghambatan sebesar 7 mm.

Abstract

Kegiatan Pengabdian kepada Masyarakat yang telah dilakukan ini bermula dari adanya keinginan untuk memberikan keterampilan yang dapat meningkatkan kompetensi guru-guru biologi. Hasil wawancara tim pelaksana pengabdian kepada Masyarakat Biologi UMRI dengan guru biologi SMAN 14 Pekanbaru, menunjukkan bahwa guru-guru Biologi SMAN 14 Pekanbaru memiliki keterbatasan ilmu dalam materi golongan darah dan tidak memiliki keterampilan dalam melakukan pemeriksaan golongan darah. Untuk itu, dengan adanya pelatihan pemeriksaan golongan darah ini, guru-guru biologi SMAN 14 Pekanbaru dapat memberikan pelajaran tentang materi golongan darah serta praktik pemeriksaan golongan darah kepada siswa. Kegiatan pelatihan ini dilaksanakan pada tanggal 1 Februari 2018. Pada saat praktik pemeriksaan golongan darah, guru-guru biologi sangat antusias mengikuti pelatihan dan mereka berharap adanya pelatihan lain yang dapat meningkatkan kompetensi para guru.

Abstract

Partners in the Stimulus Community Partnership Program (PKMS) are RT 08 RW 02 Pantai Raja Village, Perhentian Raja District, Kampar Regency. This partner group has a business as a catfish breeder (Clarias sp.). Catfish hatchery efforts in Pantai Raja Village have started 8 years ago. However, there are problems faced by catfish farmers, namely catfish attacked by diseases and death such as fungal diseases, white spots on the body of the fish. This is thought to be caused by water quality that is not good (poisonous) as well as a lot of residual fish residue at the bottom of the pond. Based on this, the team from the Stimulus Community Partnership Program (PKMS) Muhammadiyah University of Riau (UMRI) has conducted mentoring and monitoring activities to help resolve problems from partners. The forms of activities that have been carried out are socialization and training in aquaponics making. Based on discussions with participants during the socialization and training, it can be seen that participants' knowledge of good aquaponics is felt to be very lacking.

Abstract

Banjir merupakan masalah yang hampir setiap tahun melanda wilayah perkotaan maupun pedesaan. Banjir disebabkan karena tidak lancarnya saluran pembuangan air (di selokan atau badan air) yang menyebabkan terjadinya luapan air, kurangnya kesadaran masyarakat untuk tidak membuang sampah ke aliran air, dan berkurangnya lahan terbuka yang berguna untuk resapan air. Penyebab banjir di wilayah perkotaan lebih banyak disebabkan oleh tidak lancarnya aliran air (di selokan) akibat sampah yang dibuang ke aliran air dan berkurangnya daerah resapan air di pekarangan rumah. Tujuan dari kegiatan pengabdian masysrakat ini adalah untuk meningkatkan pengetahuan dan keterampilan masyarakat di Kelurahan Maharatu, Kecamatan Marpoyan Damai dalam pembuatan lubang biopori sebagai upaya untuk penanggulangan dan pencegahan banjir di sekitar pemukiman masyarakat tersebut yang nantinya dapat diaplikasikan oleh masyarakat di lingkungan sekitar rumah.

Abstract

The purpose of this research is to determine the activity of cinnamon extract (Cinnamomun burmani) as an antifungal against the growth of fungi Aspergillus flavus and Fusarium moniliforme. The procedure begins with making cinnamon extract obtained from cinnamon bark using rotary distillation method. Cinnamon extract will be tested using different concentrations of 0% (control); 0,5%; 1,0%; 2,0% and 4,0% with the well diffusion method. Based of the results, the cinnamon extract has antifungal activity against the fungi with the concentration and inhibition of 1,0% and inhibition zone diameter of 27 mm in A. flavus, while the concentration and inhibition of 2,0% with a inhibition zone of 56 mm in F. moniliforme.
