Bioethanol is a biofuel whose main ingredients are from plants and generally use microorganisms in the fermentation process. One way is to use thermophilic bacteria with the advantage of low contamination levels and better product quality. Bacteria that exist in nature are not only in a single form but also exist in the form of a consortium in which there are beneficial or detrimental bacterial interactions. Favorable bacterial interactions indicate that the bacteria are compatible. Using a consortium with compatible bacteria gives better results than using a single bacteria. This study aims to determine the compatibility and effect of a consortium of thermophilic bacteria from Mudiak Sapan hot springs on biofuel yields. This research is a descriptive research. To test the cooperation between isolates, a compatibility test was carried out using the disk diffusion method. Then the biculture conso...

During this school education focuses on the development of intellectual intelligence (IQ), which absorbs as much science but not yet touched on emotional intelligence (EQ) and spiritual (SQ). These three potentials should have been integrated in biology learning. Based on the results of research that has been done, the product results are LKPD nuanced ESQ on the cell material for students of grade VII SMP / MTs. Result of validity test with value of 81,37% by validator fulfill valid criterion, Result of validity in terms of feasibility of content, language, presentation and graphics.

The most popular form of biofuel today is bioethanol. Biofuels are considered as a suitable alternative to fossil fuels because they are more environmentally friendly. Production of bioethanol utilizing thermophilic microorganisms is more profitable because thermophilic microbes generally have the characteristics of being able to use a variety of substrates, low contamination, and resistance to high temperatures. The use of microbial consortia tends to give better results than the use of monoculture isolates to optimize bioethanol yields. The aim of this study was to determine the compatibility and ability of the best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuel. This research is a descriptive research, to test isolates of a consortium of thermophilic bacteria that produce bioethanol. The results of this study showed that consortium isolates tended to give better results ...
Suluah Bendang: Jurnal Ilmiah Pengabdian Kepada Masyarakat

Limbah dapat berasal dari sisa makanan sivitas akademika UNP maupun sisa bahan praktikum-praktikum di laboratorium biologi dan kimia FMIPA UNP. Ketika lingkungan kotor maka tidak sedikit tim cleaning service di UNP yang kewalahan. Tujuan kegiatan ini adalah bagaimana pengolahan sisa sayur dan buah di lingkungan kampus menjadi produk bermanfaat. Solusi yang ditawarkan melalui pengabdian ini adalah mengolah sampah makanan khususnya buah dan sayuran menjadi larutan ecoenzyme yang dapat digunakan untuk berbagai keperluan bagi kesehatan dan lingkungan. Oleh karena itu sangatlah tepat jika hadirnya suatu pusat produksi ecoenzyme di jurusan biologi FMIPA UNP. ECOBY adalah merek dagang ecoenzyme yang dibuat oleh unit usaha PPUPIK Jurusan Biologi FMIPA UNP berkerjasama dengan Tim Mahasiswa HMJ Biologi. Proses pembuatan ecoenzyme berasal dari sampah say...

This study aims to look at the effect of the Problem Solving Model on Science Process Skills in Grade VIII students of SMPN 34 Padang. In Indonesia, science process skills are very minimal, because in the learning process the teacher still tends to use the lecture model and question and answer method, so the science process skills are not given to students. This type of research is quasi-experimental with research design Control Group Posttest Only Design. The population in this study were eighth -grade students of SMPN 34 Padang in the academic year 2018/2019. The samples from this study were class VIII6 as the experimental class and VIII7 as the control class. The research instrument used to view the science proc...

One of solution can be issued is find and develop new potential antimicrobial derived from natural resources. Stem of Andaleh plant (Morus macroura Miq.) is potential candidate of natural resources which has antimicrobial activity, but it was an endangered species, so using this plant as antibiotic source is not wise. We can use endophytic fungi from Andaleh’s plant since they are known have the ability to produce similar antibiotic compound. So, the research aiming is to find potential candidate of endophytic fungi that have ability to produce antimicrobial compound. Stem sample of Andaleh are from Batusangkar. Stem surface sterilization was using NaOCl 0.5%. The isolation of endophytic fungi from Andaleh stem was using PDA containing Chloramphenichol 500mg/l.
