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.

This study aims to determine the types of weed vegetation in oil palm plantations (Elaeis guineensis Jacq) in Tebing Tinggi Okura, Rumbai Pesisir Sub-District, Riau. The research procedure starts from the field survey, the determination of the station is done by purposive random sampling method and is determined by three research stations namely Station I (3-5 years), Station II (5-7 years), Station III (> 7 years). Data is analyzed base on density, frequency, important value index, species diversity index (H '), dominance index, evenness index, uniformity index or similarity. The results were obtained nine types of weeds that are Asystasia gangetica weeds, Calopogonium mucunoides Desv., Davallia denticulata, Dianella ensifolia L., Elaphoglossum blumeanum, Eupatorium inulifolium Kunt, Imperata cylindrica Raeusch, Nephrolepis bisserata Schott., and Wrightia javanica.

Abstract

Jamur tiram secara alami tumbuh pada batang-batang kayu yang telah mengalami pelapukan. Jamur tiram dapat tumbuh pada media serbuk kayu, jerami padi, alang-alang, sisa kertas, ampas tebu, kulit kacang, dan bahan media lainnnya. Penelitian dilaksanakan secara eksperimen menggunakan Rancangan Acak Lengkap (RAL), yang disusun secara faktorial yang terdiri dari satu faktor dengan 5 perlakuan dan 3 ulangan yaitu P0: konsentrasi serbuk kayu 100 % dan bagas 0% (kontrol), P1: konsentrasi serbuk kayu 75% dan bagas 25%, P2: konsentrasi serbuk kayu 50% dan bagas 50%, P3: konsentrasi serbuk kayu 25% dan bagas 75%, dan P4: konsentrasi bagas 100%. Untuk menganalisis pertumbuhan jamur tiram putih, digunakananalisis varian (Anova) taraf 5% yang dilanjutkan dengan uji Beda Nyata Terkecil (BNT) taraf 5%. Hasil penelitian menunjukkan rata-rata jumlah tubuh buah berturut-turut yaitu P0 5,33 buah, P1 8,00 buah, P2 8,33 buah, P3 10,33 buah dan P4 18,00 buah. Jumlah tubuh buah tertinggi diperoleh pada perlakuan P4 yaitu 18,00. Sedangkan rata-rata berat basah jamur berturut-turut yaitu P0 33,33gr, P1 66,67gr, P2 66,67gr, P3 80,00gr dan P4 96,67gr. Berat basah jamur tertinggi diperoleh pada perlakuan P4 yaitu 96,67gr. Dapat disimpulkan bahwa pemberian bagas sebagai media pertumbuhan jamur tiram putih dapat meningkatkan jumlah tubuh buah dan berat basah jamur tiram putih.

Abstract

Gas karbon dioksida (CO2) adalah salah satu gas rumah kaca yang berpotensi menyebabkan pemanasan global. Emisi gas tersebut yang berasal dari sisa pembakaran kegiatan transportasi, permukiman, dan industri saat ini cenderung meningkat. Salah satu cara untuk menguranginya adalah dengan memanfaatkan tumbuhan untuk menyerapnya. Dalam penelitian ini dilakukan analisa Ruang Terbuka Hijau (RTH) eksisting di Kota Pekanbaru dalam menyerap emisi CO2. Untuk mengetahui kemampuan RTH dalam menyerap CO2 direncanakan dua skenario, yakni mengoptimalkan luas pepohonan pada RTH eksisting serta gabungan pengelolaan RTH yang belum dikelola pemerintah dan penambahan RTH baru. Analisis kemampuan penyerapan CO2 oleh RTH eksisting dilakukan menggunakan simulasi model program Powersim

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

The research aims to study the effect of the provision interaction Trichokompos of oil palm empty bunches (OPEB) formulated and potassium fertilizer, the main effect of both the growth and production and K nutrient uptake by plants red onion (Allium ascalonicum L.) on peat land. The study was conducted experimentally in the form of 4 x 3 factorial prepared using a completely randomized design (CRD). Trichokompos OPEB formulated as the first factor consisted of 4 levels (15, 20, 25 and 30 ton / ha) and potassium as the second factor consists of three levels (50, 100 and 150 kg K₂O / ha). The observed parameters include the number of tillers, fresh weight of tuber per m², K nutrient uptake and clump of dry weight tubers per sample red onion crop. The results showed that the 25 ton / ha Trichokompos OPEB formulated and 100 kg K₂O / ha increased fresh weight of tuber per m² until 1.7 times (71.3%), K uptake by 2.8 times (185%) and dry weight clump of tubers per sample by 2.5 times (154.5%) compared to the provision of 15 tons / ha at the same doses of potassium fertilizer (100 kg K₂O / ha). Enhancement of doses Trichokompos OPEB formulated from 15 to 25 tonnes / ha increased fresh weight of tuber per m², K uptake and dry weight of tuber per sample. Enhancement of doses to 30 tonnes / ha still affect the increase in all parameters observed. Enhancement of doses potassium from 50 to 100 and 150 kg K₂O / ha did not affect all parameters observed.

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.
