Abstract

The purpose of this study is to determine the optimum conditions of extraction usingconventional methods (maceration) and ultrasonic methods by using Response Surface Method (RSM). Thevariables used in this study are ratio of solvent to black pepper, temperature and time of extraction. Solventused in this study is 99% ethanol. The biggest yield of oleoresin using maceration method was 4.42% with aratio of solvent to black pepper for 1:4 g/mL and extraction time of 4.68 hours. The biggest yield of oleoresinusing ultrasonic method was 4.94% in the ratio of solvent to black pepper for 1:5 g/mL, temperature extraction70° C and extraction time 4 hours. GC-MS analysis showed that the piperine contained in oleoresin extractedby using maceration and ultrasonic methods are 69.92% and 63.5%, respectively. FT-IR analysis showed thatoleoresin extracted using maceration and ultrasonic methods have piperine bound. Organoleptic test showedthat oleoresin produced by using maceration and ultrasonic extraction method meet the requirement of SNI 06-2388-1998 (dark brown color, pepper smell and thick paste form).

Abstract

In this paper, preparation of N-isopropylacrylamide of varying transfer chain lengths was synthesized. p-Aminobenzamidine (PABA) was chemically linked to the carboxyl groups of these polymers to obtain thermoprecipitating affinity polymers. The polymer to which PABA was linked through a carboxyl groups exhibited increase with polymer containing various PABA. Investigations on experiment showed that this enhancement in trypsin binding by the polymers was due to the p-aminobenzamidines to microenvironmental effects. Recovery and specific activity of the trypsin recovered increased with the low molecular weight of polymer.Keywords: Ligand, p-aminobenzamidine, trypsin, recovery, affinity precipitation

Abstract

Abstrak. Keberadaan amonia berlebih sangat berbahaya bagi kehidupan di lingkungan air. Amonia merupakan polutan yang sangat berbahaya karena dalam jumlah yang besar dapat menyebabkan kematian organisme. Untuk mencegah dan mengatasi permasalahan pencemaran air oleh limbah amonia dapat digunakan beragam metode. Salah satu metode yang dapat digunakan adalah fitoremediasi. Fitoremediasi adalah upaya penggunaan tanaman dan bagian-bagiannya untuk dekontaminasi limbah dan masalah-masalah pencemaran lingkungan. Pada proses fitoremediasi tidak semua tanaman dapat digunakan dikarenakan semua tanaman tidak dapat melakukan metabolisme, volatilisasi dan akumulasi semua polutan dengan mekanisme yang sama. Tujuan dari penelitian ini adalah mengetahui kemampuan tanaman air Typha latifolia menyerap amonia di dalam limbah, dan mengetahui pengaruh variabel-variabel yang divariasikan di dalam penelitian. Hasil penelitian menunjukkan bahwa tanaman air Typha latifolia memilki kemampuan yang baik dalam menyerap amonia. Penurunan konsentrasi amonia berbanding lurus dengan tinggi tanaman dan HRT (Hydraulic Retention Time).

Abstract

Biodegradable plastic is an alternative to conventional plastic which has been very difficult to degrade and causes environmental pollution. Biodegradable plastic raw materials come from plants or plant wastes, so they are easily degraded by the environment and the utilization of waste becomes more efficient. The general objective of this study is to obtain the characteristics of plastics that meet the standards by varying the concentration of the materials used. This study used Kepok banana hump starch with variations in the concentration of chitosan, sorbitol, and cinnamon oil. The variable used is the ratio of weight of starch and water (1: 5). The concentration of chitosan nanoparticles was 0.25%, 0.5%, and 0.75%, sorbitol concentrations were 2 ml, 4 ml, and 6 ml, and the concentration of cinnamon was 0%, 0.5%, and 1%. Tests carried out are tensile strength, elongation of break, water absorption, and biodegradability. The best tensile strength results are 19.6 MPa, the best elongation is 47.69%, the highest water absorption is 53.77% and the lowest is 22.63%, and the complete degradation takes the longest time of 77 days.

Abstract

Nutmeg oil, also known as essential oil, is an oil extracted from the seeds or leaves of nutmeg through a distillation process. Nutmeg oil has several advantages, including as an antibacterial ingredient, an additive in the perfume industry, and as a raw material for medicines in the pharmaceutical industry. In this study, the essential oil from nutmeg leaves was produced using the steam-water distillation method, where the nutmeg leaves were dried before the steam-water distillation process was carried out. As a fixed variable, 150 g of bulk cooking oil and 150 g of bimoli cooking oil were used, while as a variable, steam-water distillation temperature was used with temperature variations of 105 oC, 115 oC, and 125 oC. Samples of 1 mL, 2 mL, 3 mL, and 4 mL of nutmeg leaf oil were mixed with bulk cooking oil to compare the free fatty acid oxidation ability and peroxide value after 1 day, 3 days, 5 days, and 7 days. Analysis of the compound content of nutmeg leaf oil, free fatty acids, peroxide number, and antioxidant activity was carried out using GC-MS and 0.004% DPPH. The production of nutmeg leaf oil was obtained as much as 91 ml by steam distillation at a maximum temperature of 125 oC. Using a DPPH of 0.004 percent and a quantitative measure of IC50, the optimal antioxidant activity at 125 oC was found to be 2.03 percent. A comparison of free fatty acid numbers and peroxide values found in this study revealed that pure bimoli cooking oil had the lowest free fatty acid and peroxide values.

Abstract

The rapid development of industrialization and urbanization in the world impact increased water pollution. Human activities, such as dam constructions, excessive water consumption, severance of river flows, compaction of riverbanks, and excessive use of riverbed vegetation, disrupt river flow and alter the original hydrological cycle. In response to these conditions, this study aims to analyze water quality and river quality status to set up a watershed environmental management strategy in Aceh Province as a case study. River water quality was analyzed descriptively by comparing the results of laboratory tests with parameters, namely TSS, pH, BOD, COD, DO, total phosphate, nitrate, and fecal coli. These parameters were then transformed into the environmental index (Water Quality Index and Pollution Index). It was found that Water Quality Index (WQI) results are shown from 50 to 70. WQI with the Good category is at Kr. Weh which is in the Central Aceh city. The medium-less type is found in 10 watersheds. The water quality with the category of Less is found at 3 points, namely Kr. Aceh, Cr. Doy, and Cr. Daroy. The quality of the river water in the Aceh region, from upstream to downstream, has decreased in quality with a lightly polluted status based on the Minister of Environment and Forestry of the Republic of Indonesia No. 27 of 2021 for class II.
