Abstract

ABSTRACT Quantitative Structure-Activity relationship study of 13 Indolylisoxazoline analogues as antiprostat agent using multiple linear regression (MLR) has been done. Geometri optimization of Indolylisoxazoline analogues using molecular mechanics (MM+) method. The best QSAR model from regression analysis is log IC50 Pred = 30,877 - 71,847 x qC10 + 165,070 x qC11 + 70,106 x qC13 with most influents descriptor to antiprostat activity are qC10, qC11 dan qC13.

Abstract

This study aims to detect synthetic dyes in JAS (School Children Snacks) using a chelating agent (CAT) from bagasse waste. Instrumentation used in the analysis was spectronic 20D. Sugarcane pulp cellulose products as CAT adsorbent rhodamine B coloring agent, metanil yellow and tartrazine in JAS were applied to 10 types of soft drink samples circulating in the market in Gorontalo City. The method used is the adsorption method. The adsorption capacity produced by cellulose with 75% content and α-cellulose content was 37.8% for sample 1 (56%) sample 2 (12%), sample 3 (83%), sample 4 (54%), sample 5 (45%) , sample 6 (54%), sample 7 (51%), sample 8 (27%), sample 9 (69%) and sample 10 (25%). The adsorption capacity produced by cellulose was 88.4% and α-cellulose content was 45.2% for sample 1 (56%) sample 2 (12%), sample 3 (83%), sample 4 (54%), sample 5 (45%) , sample 6 (54%), sample 7 (51%), sample 8 (27%), sample 9 (69%) and sample 10 (25%).

Abstract

Limbah cangkang bekicot (Achatina fulica) memiliki potensi untuk dikembangkan sebagai sumber Kalsium Oksida (CaO). Limbah cangkang bekicot (Achatina fulica) memiliki kandungan mineral kalsium karbonat (CaCO3) yang tinggi. CaCO3 dapat didekomposisi menjadi CaO pada pemanasan suhu tinggi. Dalam penelitian ini, CaO disintesis dari Limbah cangkang bekicot (Achatina fulica) dikalsinasi 900 °C selama 10 jam (LCB-900-10) dan kemudian CaO yang dihasilkan dari proses kalsinasi dikarakterisasi menggunakan X-Ray Diffraction (XRD) dan XRay Fluorocense (XRF). Dari hasil difraktogram XRD senyawa CaO dari LCB-900-10 terdapat puncak lime yang berturut-turut beserta nilai intensitas relatif yang cukup besar di antaranya adalah pada 2θ = 32,1767°(37,9%); 37,3224°(100%); 53,8253°(55,42%); 64,1206° (15,76%); 67,3433° (16,32%); 79,6249° (5,08%); 84,7873° (0,22%); 88,4925° (5,35%); 91,4306° (14,88%), dengan kandungan CaO dilihat dari karakterisasi menggunakan XRF sebesar 98,629%.Limbah cangkang bekicot (Achatina fulica) memiliki potensi untuk dikembangkan sebagai sumber Kalsium Oksida (CaO).

Abstract

Penelitian ini bertujuan untuk mengkonversi lignoselulosa dari jagung tongkol limbah menjadi bioetanol sebagai bahan bakar alternatif terbarukan. Proses pembuatan etanol dari kotoran jagung sampah dapat melalui tiga tahapan yang penting, menghidrolisis lignocellulose menjadi gula, fermentasi gula ke dalam pemurnian etanol andethanol. Proses menghidrolisis kimia menggunakan asam sulfat encer. Fermentasi gula ke etanol menggunakan Saccharomyces Cerevisiae, sedangkan pemurnian alkohol yang dihasilkan melalui proses distilasi. Hasil penelitian menunjukkan bahwa alkohol (etanol) konsentrasi yang diperoleh masih di bawah standar yang diinginkan sebagai alternatif energi untuk bahan bakar fosil.

Abstract

4-methyl acid octanoat and ethyl-4-methyl Oktanoat aggregation of kumbang badak (Oryctes rhinoceros Linn) using Mannich's reaction and Claisen rearrangement has been synthesized. The synthesis of compounds includes five phases: synthesis, separation, purification and structure determination. The pure compounds produced from each stage of further synthesis are characterised using mass spectroscopy and infra-red spectroscopy. 4-Methiloctanoic acid synthesis products and ethyl-4-methyloktanoat pheromone aggregation kumbang badak (Oryctes rhinoceros Linn) use Mannich reaction and Claisen rearrangement 50.53% and 63.69% respectively.
