Abstract

One of the determination factors of nutmeg oil quality is myristicin content because it gives a distinctive aroma to nutmeg oil. The purification process of nutmeg oil requires a long distillation time thus refining techniques which more efficient with quality results that meet the standards are needed. This study aimed to determine temperature effect on isolation of myristicin from nutmeg oil using a rotary evaporator. The stages of this research were carried out in two stages, namely concentration and purification stage, each using a temperature variation of 140 0C, 145 0C and 150 0C at  300 mbar pressure for 1 hour. The concentration process at a pressure of 300 mbar with a temperature variation of 150 0C for 1 hour process obtained 22.26% myristicin. The next stage of purification of nutmeg oil carried out at a pressure of 300 mbar with a temperature of 150 0C for 1 hour was able to isolate myristicin up to 53.41%. The results of gas chromatography-mass spectrophotometry (GCMS) on nutmeg oil at a pressure of 300 mbar with a temperature of 150 0C for 1 hour process with 53.41% myristicin content had met Indonesian National Standard (SNI) 06-2388-2006 with a minimum value of 10%.Keywords: myristicin, nutmeg oil, rotary evaporatorABSTRAKSalah satu faktor yang mempengaruhi kualitas minyak pala adalah kandungan miristisin, karena memberikan aroma khas pada minyak pala. Proses pemurnian minyak pala membutuhkan waktu penyulingan yang cukup lama sehingga diperlukan teknik pemurnian yang lebih efisien dengan kualitas hasil yang memenuhi standar. Penelitian ini bertujuan untuk mengetahui pengaruh temperatur pada isolasi miristisin dari minyak pala menggunakan rotary evaporator terhadap kadar miristisin. Penelitian dilakukan dalam dua tahap yaitu tahap pemekatan dan tahap pemurnian, masing-masing menggunakan variasi suhu 140 0C, 145 0C dan 150 0C pada tekanan 300 mbar selama 1 jam. Proses pemekatan pada tekanan 300 mbar dengan variasi suhu 150 0C selama 1 jam diperoleh miristisin sebesar 22,26%. Tahapan berikutnya yaitu pemurnian minyak pala yang dilakukan pada tekanan 300 mbar dengan temperatur 150 0C selama 1 jam mampu mengisolasi miristisin hingga 53,41%. Hasil uji gas chromatography-mass spectrophotometry (GCMS) minyak pala pada tekanan 300 mbar dengan temperatur 150 0C selama 1 jam proses dengan kadar miristisin 53,41% telah memenuhi Standar Nasional Indonesia (SNI) 06-2388-2006 dengan nilai minimum 10%.

Abstract

Adsorption technology is one of the technologies that can be applied to control exhaust emissions. This study aimed to utilize the skin biomass waste shell of coffee beans as activated carbon to absorb CO and NOx emissions in vehicle exhaust. Conversion of coffee beans shell into carbon was obtained at 31.14% at 450 oC. The absorption of exhaust emissions was done on four-wheeled diesel vehicles by placing activated carbon in the flue gas channel with two variations of pellet and hollow briquettes. The results showed COE emission reduction of 6.62-39.02% and NOx exhaust gas reduction of 13.08-39.05%. The absorption process also greatly influenced the mechanism of contacting exhaust emissions with the adsorbent. From the results obtained by activated carbon with hollow briquette form gave higher percentage of CO2 and CO2 emissions elimination compared to activated carbon in pellet form.Keywords: acivated carbon, adsorpstion, coffee bean shell, emission gasABSTRAKTeknologi adsorpsi merupakan salah satu teknologi yang dapat diterapkan untuk mengontrol emisi gas buang. Karbon aktif selama ini dikenal sebagai adsorben yang kapasitas adsorpsi yang baik. Penelitian ini bertujuan untuk memanfaatkan limbah biomassa kulit cangkang biji kopi sebagai karbon aktif untuk menyerap emisi CO dan NOx pada gas buang kendaraan. Pemanfaatan limbah biomassa cangkang biji kopi menjadi karbon aktif menunjukkan potensi yang baik. Konversi kulit cangkang biji kopi menjadi karbon diperoleh sebesar 31,14% pada temperatur 450oC. Penyerapan emisi gas buang dilakukan pada kendaraan roda empat bermesin diesel dengan menempatkan karbon aktif pada saluran gas buang dengan dua variasi yaitu pelet dan hollow briket. Hasil yang diperoleh menunjukkan penurunan emisi gas buang CO sebesar 6,62-39,02% dan penurunan emisi gas buang NOx sebesar 13,08-39,05%. Proses penyerapan juga sangat berpengaruh kepada mekanisme pengontakan emisi gas buang dengan adsorbent. Dari hasil yang diperoleh karbon aktif dengan bentuk hollow briket memberikan persentase penyisihan emisi gas buang CO dan NOx yang lebih tinggi dibandingkan karbon aktif dengan bentuk pelet.

Abstract

The industrial liquid waste is very dangerous because it still contains elements of pollutants with a relatively large waste parameters. One way that can be used is by the method of adsorption or absorption. In this research the absorbent used is Natural Zeolite in nano meter scale. Zeolitewith nano meter size is obtained by smoothing using ball mill for 15 - 20 hours. Furthermore, nano zeoliteis activated physically and chemically. Nano zeolite will be characterized using X-ray Diffraction (XRD), Fourier Transform Infarared (FTIR), Scanning Electron Microscopy (SEM), and characterization of N adsorption desorption. Results of the study obtained the highest adsorption capacity and percent removal is performed by ziolites that are activated with nano-size ZnCl2 with a value of 440.5 mg/g for adsorption capacity and 65.9% for percent removal. In this study, the equation for calculating the zeolite performance in lowering the COD content in the effluent was used Langmuir’s isotherm equation. The determinant coefficient (R22) of the Langmuir isotherm equation for 35 μm zeolite and non-activated nano meter performance were 0.9974 and 0.9983, respectively. While unzaked zeolitefor size 35μm and nano meter are respectively equal to 0,9977 and 0,9197.

Activated carbon was prepared from Yellow bamboo (Bambusa vulgaris striata) via KOH activation to adsorb Pb ions from aqueous solutions. This research aimed to determine Pb adsorption using activated carbon. The adsorption process was performed by flowing the Pb solution through the fixed-bed column filled with the prepared activated carbon. The applied flow rate varied between 5 mL/min and 10 mL/min. The microstructure of activated carbon was observed using Scanning Electron Microscope (SEM). The obtained results showed that the highest Pb concentration at 5 mL/min was 5.82 mg/L.
