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:
Bubuk kulit batang sagu (Metroxylon sagu) berpotensi sebagai adsorben karena mengandung selulosa, hemiselulosa dan lignin. Tujuan dari penelitian ini adalah menentukan kemampuan aktivator kimia berupa asam asam klorida dan asam sulfat untuk memperbaiki kualitas adsorben dari bubuk kulit batang sagu sesuai standar SNI 06-3730-1995. Metode yang digunakan adalah dengan sistim bath, dimana bubuk kulit batang sagu diaktivasi melalui perendaman dengan HCl dan H2SO4 selama 24 jam menggunakan variasi perbandingan berat adsorben dan aktovator 1:1, 1:2 dan 1:3. Analisis di uji melalui karakterisasi meliputi kadar air, kadar abu, daya jerap terhadap iodium dan daya jerap terhadap metilen biru, serta gugus fungsi. Dari hasil penelitian, diperoleh kedua aktivator menunjukan rasio 1: 2 memmberikan kondisi yang optimal kadar air, kadar abu, daya jerap terhadap iodium dan metilen biru, luas permukaan masing-masing sebesar 1,64%; 3,14%; 261,41 mg/g; 4,80 mg/g; 17,76 m2/g untuk aktivator HCl dan 2,67%; 3,20%; 261,10 mg/g; 4,79 mg/g; 17,67 m2/g untuk aktivator H2SO4. Dari penelitian ini dapat disimpulkan bahwa penggunaan larutan HCl dan H2SO4 tidak memperlihatkan perbedaan yang signifikan sebagai aktivator untuk miningkatkan kualitas adsorben bubuk kulit batang sagu, nilai daya jerap iodium dan metilen biru kedua aktivator tersebut belum mampu menjadikan bubuk kulit batang sagu sebagai adsorben sesuai standar SNI 06-3730-1995.

Abstract:
The purpose of this study is to analyze the factors in community-based waste management and analyze the environmental, economic and social impacts of waste management in Marpoyan Damai District, Pekanbaru City. The approach of this research is quantitative analytic with cross sectional research design. The population in this study were all family heads in the Tangkerang Barat sub-district Marpoyan Damai Pekanbaru City as many as 4,345 households with a sample of 98 people. The results of this study are there is an influence between education (p value = 0.006), infrastructure (p value = 0.003), knowledge (p value = 0,000) with community participation in household waste management in Marpoyan Damai District, Pekanbaru City. The logistic regression analysis results found that the education variable has a value of p = 0.048 and an OR 2.888 which means that education has 2 times the risk of waste management. Infrastructure variable has a value of p = 0.001 and OR 6.838 which means that infrastructure has 6 times the risk of waste management. Knowledge variable has a value of p = 0,000 and OR 9,617 which means knowledge has 9 times the risk of waste management. The environmental impact of proper waste management is decreasing the volume of waste generation and environmental damage. Economically, there is currently no economic value to waste management, other than the public does not understand waste management that has economic value with 3R. Inadequate waste management causes low levels of public health, so people need to pay more for treatment. Socially, most people do not care about waste management and even though there is waste management it is still individual and not organized in an integrated way.

Abstract:
Cancer is a disease characterized by uncontrolled cell growth and the ability of these cells to attack biological tissue. Various attempts have been made, one of them with treatment to kill cancer cells, but not a few of these efforts actually cause side effects. This fact demands the need for a safe alternative way to treat cancer using natural ingredients. One of the local natural resources that has the potential to treat cancer is Majapahit (Crescentia cujete). In this study, Majapahit (C. cujete) stem extracts were carried out which have anticancer activity. The first stage was screening by conducting a qualitative analysis of the ethanol extract of the stem of the majapahit plant (C. cujete). Furthermore, a toxicity test was carried out against Artemia salina Leach using the Brine Shrimp Lethality Test (BST) method. Phytochemical testing was carried out to check the content of secondary metabolite compounds contained in the majapahit stem extract, and the results were positive for flavonoids, tannins, saponins and phenolics. This data, supported by spectrophotometric tests, proved that the largest concentration of the ethanolic extract of the majapahit (C. cujete) stem was 24.05% tannin. Then the LC50 test from the toxicity test of the active component of majapahit plant stem extract (C. cujete) against Artemia salina Leach showed a concentration of 0.01 µg / mL and 0.04 µg / mL, namely with a percentage below 50%.

Abstract:
Determination of compounds and temperature modeling during heating of limestone have been carried out to obtain pure CaO from Papua limestone. . The purpose of this research is to determine the compounds, morphology and characteristics of each element and molecule present in limestone from Papua and to simply model the optimum temperature to obtain CaO. From the results of XRF testing, there is one main element that contains the most chemical elements in the limestone sample from black soil (sample 1) and perumnas three (sample 2), namely Ca (calcium) with weight percent 99.57 and 99.69. XRD results are also supported from characterization with EDS where the dominant elements of sample 1 are O, Ca and Mg in sample 2 dominant elements Ca, O and C. Then based on SEM analysis, the morphology of CaMg (CO3) 2, Ca (Co3) and MgCa ( Co3) resembles a cube but the particle size is uneven and irregular due to impurities. The temperature obtained based on the results of this calculation is 12800C.

Abstract:
Peningkatan emisi CO2 sejalan dengan peningkatan jumlah penduduk serta aktivitas sehari-hari dalam menggunakan energi. Konsumsi energi yang digunakan oleh setiap rumah tangga untuk memenuhi kebutuhan hidup seperti penggunaan LPG dan konsumsi daya listrik. Tujuan dari penelitian ini adalah untuk mengetahui emisi CO2 dari pemakaian LPG dan konsumsi listrik di Kota Pekanbaru. Metode Krejcie and Morgan digunakan untuk menentukan jumlah sampel dan untuk menghitung emisi CO2 adalah metode IPCC 2006. Sampel yang digunakan dalam penelitian ini adalah sebanyak 167 Rumah Tangga di Kota Pekanabaru. Total emisi CO2 dari rumah tangga di Kota Pekanbaru adalah sebesar 40.806,386 Ton CO2/Bulan dengan rata-rata setiap CO2 rumah tangga menghasilkan emisi CO2 sebesar adalah 0,1570409 Ton CO2/Bulan. Konsumsi listrik merupakan penyumbang emisi CO2 terbesar yaitu 34.602,51363 Ton CO2/Bulan dan LPG menyumbang emisi sebesar 6.204,424 Ton CO2/Bulan. Maka dapat diartikan bahwa konsumsi listrik dalam sektor rumah tangga berkonstribusi lebih besar menghasilkan emisi CO2 .
