Abstract

AbstrakFenol adalah senyawa organik yang bersifat toksik dan larut dalam air, sehingga mudah menimbulkan pencemaran pada perairan dan menurunkan kualitas air. Penelitian ini bertujuan untuk melihat potensi tiga isolat aktinomisetes asal tanah gambut Riau dalam Minimal Salt Medium yang mengandung fenol pada konsentrasi 0 ppm, 200 ppm, 400 ppm, dan 600 ppm serta mengetahui kemampuan aktinomisetes dalam mendegradasi fenol pada konsentrasi 600 ppm menggunakan metode folin ciocalteau. Potensi pertumbuhan isolat L121, L18, L11 menunjukkan total populasi tidak berbeda nyata dengan penambahan 400 ppm dan 600 ppm fenol, tetapi berbeda nyata terhadap 0 ppm dan 200 ppm fenol. Potensi pertumbuhan tertinggi terdapat pada isolat L121 dan terendah pada isolat L11. Kemampuan degradasi  fenol oleh  masing-masing isolat adalah  L121 sebesar 570,80 ppm (95%),  L18 sebesar 218,85 ppm (36%)  dan L11 sebesar  97,21 ppm (16%)  dari konsentrasi fenol awal 600 ppm pada Minimal Salt Medium. Isolat aktinomisetes ini berpotensi dikembangkan untuk penanggulangan pencemaran di lingkungan.Abstract Phenol is an organic compound is toxic and easily soluble in water so easy to cause pollution in a waters such as water quality degradation. The aim of this research is to see the potential of three isolates of actinomycetes from Riau peat soil in Minimal Salt Medium containing phenol concentration 0 ppm, 200 ppm, 400 ppm and 600 ppm and to know the ability of actinomycetes in degradation of phenol at the concentration of 600 ppm using folin ciocalteu. The growth potential of L121, L18, L11 isolates showed the total population was not significantly different with the addition of 400 ppm and 600 ppm of phenol but significantly different from 0 ppm and 200 ppm of phenol. The highest growth potential was found in L121 isolate and lowest in L11 isolate. The degradation ability of phenols by each isolate was L121 570.80 ppm (95%), L18 218.85 ppm (36%) and L11 was able to degrade phenol 97.21 ppm (16%) from the initial phenol concentration of 600 ppm at Minimum Salt Medium.These actinomycetes have the potential to be developed for the overcome of pollution in the environment.

Abstract

Penggunaan pengawet alami untuk mempertahankan mutu dan memperpanjang masa simpan ikan merupakan cara yang aman dan tidak berdampak buruk bagi kesehatan. Beberapa bakteri Asam Laktat (BAL) diketahui mampu menghasilkan bakteriosin yang berpotensi digunakan sebagai biopreservatif bahan pangan. Tujuan dari penelitian ini adalah untuk mengetahui kemampuan bakteriosin BAL sebagai biopreservatif untuk mempertahankan mutu dan masa simpan ikan patin (pangasius sp) yang pengaplikasiannya dikombinasikan dengan Natrium klorida (NaCl) and Natrium Asetat (CH3COONa). Metode yang digunakan adalah metode eksperimen dengan tiga perlakuan yaitu kontrol , penambahan BAL, serta kombinasi BAL dengan 3% NaCl dan 3% Na As).Diamati pH dan dihitung jumlah bakteri dengan metode TPC (Total Plate Count).Hasil penelitian menunjukkan perlakuan kombinasi BAL , NaCl dan BAL dengan 3% NaCl dan 3% Na As memiliki efektivitas paling tinggi dalam mempertahankan mutu dan masa simpan ikan patin, mencapai 7 hari lebih lama 3 hari dibandingkan kontrol sedangkan perlakuan kombinasi dengan isolat BAL  5 hariKey words: bakteriosin, bakteri asam laktat, masa simpan ikan, ikan patin (Pangasius sp)

Abstract

Lead is a heavy metal that is highly toxic, detectable to all inanimate objects in the environment and throughout biological systems. The purpose of this study is to test the biosorption capability of Lactic Acid Bacteria (BAL) of Riau against heavy metal Lead (Pb). Biosorption test is conducted with Grow BAL SB3 and SB6 on MRS broth medium with Pb concentration of 5, 10 and 50 ppm.Previously made growth curve to know the optimum growth time and the best incubation time. biosorption was done by measuring Pb which was absorbed by AAS (Automathic Absorption Sphectrofotometer). The result showed that isolate BAL SB3 able to absorb Pb at concentration 5, 10 d 50 ppm with biosorption efficiency 46,6%, 36,8% and 30,7% . Whereas SB6 with biosorption efficiency is 44,8%, 32,2% and 25,7%

Abstract

Endophytic bacteria have been known to produce high levels of secondary metabolites. The sterile leaves of the sea fern (Acrostichum aureum L.) contain many phytochemical compounds. This sea fern is often found in peat swamp areas. The aim of this study was to isolate, partial characterization, and analysis of bioactive compounds from endophytic bacteria of sea ferns to determine their bioactive compounds. Endophytic bacteria were isolated by a direct technique using nutrient agar (NA) media. In this study, the endophytic bacteria were characterized by macroscopic, microscopic, and Gram. Several tests were further performed, namely phytochemical test and Fourier Transform Infra Red (FT IR) FTIR tests from a crude extract of secondary metabolites of bacteria. The results of the isolation obtained six isolates of endophytic bacteria consisting of all isolates were Gram-negative. The phytochemical test results for the six isolates were positive for alkaloids and saponins but no steroids. Based on the results of phytochemical tests and FT IR, it is suspected that the isolate DSB 1.6 has similarities with the alkaloid functional group. This endophytic bacterial isolate can be developed as a candidate for produced of pharmacological compounds.

Abstract

VCO Bertuah is an MSME in Pekanbaru that produces virgin coconut oil. Bertuah VCO has legality permits in the form of IUMK, NIB and P-IRT Certificate. However, Bertuah VCO does not have a halal certificate, BPOM distribution permit, and product SNI. The marketing of Bertuah VCO products is mostly done online, especially through social media platforms such as Facebook and Instagram. Other digital marketing strategies such as youtube and websites have not been carried out. Based on the results of the activity, it can be concluded that UMKM need assistance to take care of business legality. It is necessary to have active communication between UMKM and government agencies in charge of business licensing. Assistance activities have succeeded in increasing partners' understanding of the business legality management procedures. Assistance activities are very helpful for partners in preparing documents for business legality requirements. Assistance activities increase partners' understanding of digital marketing strategies through the website, instagram and youtube. Assistance activities help partners prepare advertising content in the form of product photos, instagram feed designs, video testimonials, and good ad copywriting.

Abstract

The World Health Organization has designated Covid-19 as a pandemic that causes activities outside the home to be restricted. In order to maintain health during the pandemic, many people are starting to choose foodstuffs produced from organic farming. The purpose of this activity is to provide information and motivation to society for reuse household waste with appropriate technology to produce compost. This service activity was carried out in Air Dingin Village, Bukit Raya District, Pekanbaru. The initial stage conveys material about the importance of maintaining health during the pandemic by consuming organic vegetables and fruits grown in their respective yards. Furthermore, the practice of making compost using the direct-use compost method and composting in a composter pot. Composting that reuses household waste has succeeded in opening up insight into the importance of the community's role in personal and environmental health and the public's understanding that a healthy life doesn't have to be expensive. In this activity, the participants showed their enthusiasm and stated that they would practice and share their knowledge with others in making compost to overcome the problem of household waste. This activity is also beneficial to keep the environment clean, healthy and beautiful.
