Abstract

Morfologi membran hibrid polisulfon-lempung dengan zat aditif PEG dan lempung (PEL 1) berbeda dengan membran hibrid polisulfon-lempung dengan zat aditif lempung saja. Penggunaan 2 jenis zat aditif pada membran PEL 1 menyebabkan jumlah pori lebih banyak, ukuran pori lebih kecil dan distribusi pori lebih merata dibandingkan membran PL 1 yang hanya menggunakan zat aditif lempung saja. Zat aditif PEG pada membran PEL 1 berperanan pada pembentukan pori membran dengan cara meningkatkan koneksitas pori, sedangkan peranan lempung pada membran PEL 1 dan PL 1 melalui interkalasi visit host ke dalam polimer organik.

Abstract

Kristalinitas membran hibrid polisulfon-lempung dalam larutan casting yang dikoagulasikan dalam media koagulasi air dan campuran air-2 propanol menunjukkan hasil yang berbeda. Pengukluran dilakukan menggunakan menggunakan difraktometer sinar-X Schimizu Maxima 7000 pada sudut hamburan (2θ) 5o-35o, dengan ukuran sampling puncak 0.02o dan kecepatan pengamatan (scan) 2o/menit. Derajat kristalinitas membran A (koagulan air) adalah sebesar 63,1185, sedangkan membran B (media koagulasi campuran air-2propanol adalah 31,7691. Perbedaan derajat kristalinitas ini disebabkan pengaruh halangan sterik dari media koagulasi dan kecepatan difusi pertukaran antara pelarut dan non pelarut pada proses koagulasi pembentukan membran.

Abstract

Free radicals are molecules that lose electrons in their outer orbitals so that the number of electrons becomes odd and unstable. Free radicals can damage various macromolecule cells including proteins, carbohydrates, fats. Antioxidants are compounds that can donate one or more electrons to free radicals. Avocado leaves contain high bioactive components that can be used as a source of natural antioxidants. Avocado leaves that have been dried, mashed and then shifted with methanol. The extracts were tested by phytochemical screening, including flavonpoid, phenolic, tannin and antioxidant activity using the DPPH (2,2-diphenyl-1-picrylhidrazyl) method. This method is based on the reduction of 2,2-diphenyl-1-picrylhydrazyl (DPPH) against free radicals which causes a change from purple to yellow 2,2-diphenyl-1-picrylhydrazyl) (DPPH). From the research, the IC50 values ​​in avocado leaves were 118.8056 µg / mL and 7,276 µg / mL on ascorbic acid as a positive control. From the IC50 value obtained, it is known that the methanol extract of avocado leaves has strong antioxidant activity to fight free radicals.

Abstract

Every day people always produce household waste. In an average day each resident produces 2-3 liters of waste. To reduce the amount of waste that is disposed of in the TPA, the community needs to carry out their own waste processing techniques. The most appropriate method of processing organic waste is to use the compost. Compost is an effort to process organic waste through a controlled decomposition process. The main product of composting is environmental cleanliness, because the amount of disposing organic waste in the landfill that can be reduced. Subsequence, it can be obtained the compost yield as another advantage. Composting with the Takakura method is very suitable for tropical areas and household scale.

Abstract

Membran hibrid polisulfon-lempung dibuat dengan melarutkan bahan dasar polimer polisulfon dan bahan an organik lempung. Membran hibrid polisulfon-lempung PEL 1 menggunakan zat aditif polietilen glikol (PEG) sebanyak 9%, lempung sebanyak 9%, sedangkan membran PL 1 tanpa menggunakan PEG, sehingga lempungnya sebanyak 18%. Kedua membran dibuat dengan metode inversi fase. Karakterisasi sifat termal membran hibrid polisulfon-lempung dilakukan menggunakan DTA-TGA Perkin Elmer kopling. Persentase lempung yang tinggi menyebabkan tinginya persentase kandungan silika (SiO2 )pada membran PL 1 dibandingkan membran PEL 1 partikel silika yang terdapat pada lempung akan berinteraksi kuat dengan matriks polimer menghasilkan membran hibrid yang mempunyai stabilitas termal tinggi. Termogram dekomposisi material membran PEL 1 pada suhu 400 -600 o C sekitar 70% dan sekitar 50% pada membran PL 1.

Abstract

Garbage is a household product, which is produced every day. The household garbage becomes a big problem, if it can not be handled properly. Residents of RT 04 RW 09 Binawidya, Tampan district, city of Pekanbaru have experienced problems with waste such as unpleasant odors due to the accumulation of house yard waste before being disposed to a final disposal site. To reduce this problem, there are many solutions that can be done. One of them is to utilize organic waste from household, which is processed into Eco-Enzyme. The eco-enzymes made from household waste such as vegetable residues and fruit peels. It can produce environmentally friendly products such as floor cleaners, plant fertilizers, water purifiers and others. The eco-enzyme is very easy to make. The ingredients are used organic waste (vegetables and fruit peels), sugar and water in a ratio of 3:1:10. This paper explained the eco-enzyme production training that was given to housewives, aiming to use the waste produced by their households into useful products.

Abstract

Pekanbaru City is a metropolitan city with a very dense traffic volume with a low level of discipline for road users. Violations of traffic signs often occur and a sense of care to comply with traffic regulations is still low, accidents often occur. As a result of undisciplined road users, it creates anxiety and worries about accidents. For this reason, it is necessary to conduct traffic safety education. Traffic counseling should be taught from an early age, where children are able to provide an understanding of good behavior in order to form a disciplined child character. The teaching method is adjusted to the age where the Shalsabila PAUD children are aged 2.5 - 5 years which is included in the category of Toddler and preschool age. The method used is made fun by telling stories, singing and playing. So they are very enthusiastic and happy. Most preschoolers begin to understand and can distinguish what can be done and what can't be done.

Abstract

The high level of population density in RT 002 / RW 009 Labuh Baru Timur Village, Payung Sekaki District, Pekanbaru City has the potential to be a contributor to CO2 carbon dioxide emissions. The resulting carbon emissions are from electrical energy and food consumption. The formulation of the problem of this research is how the value of the carbon footprint resulting from the consumption of food and electricity energy. The purpose of this study is to determine the value of carbon emissions. Based on the data obtained, the value of emissions from the electricity sector is 1061.106786 (kg CO2)/day, the food consumption sector is 526.33299 (kg CO2)/day. The highest emission value produced by the electricity sector from the 32nd respondent was 18.39823 (kg C02)/day, and the food consumption sector from the 48th respondent was 13.55319 (kg C02)/day.
