Abstract

Wastewater of detergent residual that comes from the washing process (laundry) has the potential to pollute environmental sustainability such as rivers and soil if it is thrown away in large volumes without any prior processing. Easy and inexpensive methods for processing laundry wastewater for household-scale have been carried out and proven to reduce levels of pollutants contained in laundry wastewater such as phosphate and ammonia. This study aims to determine the effect of the use of filtration media using a combination of activated charcoal adsorbent, zeolite, silica sand, anthracite and ferolite in reducing phosphate and ammonia levels in laundry wastewater. Based on the results of laboratory tests on the parameters of phosphate and ammonia test, it was found that after the filtration process, there was a decrease in phosphate and ammonia levels in the samples of laundry wastewater by 83.3% and 63.6% respectively. Thus, from the research data, it can be concluded that the filtration media in the form of a combination of adsorbents used in this study proved to be able to reduce phosphate and ammonia levels in samples of laundry wastewater.

Abstract

One of the processed coconut products that is beneficial to health and has been widely used as an industrial raw material is VCO. Traditional rural communities and households have produced their own VCO for personal consumption because of its health benefits. However, the production process of VCO which still traditionally produces VCO products with a standard of quality and yield that has not been maximized. The research was carried out by enzymatic method, which added the enzyme bromelain contained in pineapple stem extract into coconut milk. The VCO product obtained was then purified by zeolite adsorbent, and water content and free fatty acid levels were tested. The results showed the highest VCO yield was found at a concentration of 20%, which was 36% and the purification of VCO with adsorbent zeolite was proven to reduce water content and free fatty acid levels with the highest percentage decrease in water content by 66%, and the highest percentage decrease in free fatty acid 63%. From the results of the study it can be concluded that the addition of pineapple stem extract containing the enzyme bromelain in the production of VCO can increase the yield of VCO to a maximum of 35.9% and purification of VCO samples with adsorbent zeolite proven to help reduce water content and free fatty acid levels.

Abstract

In this study, coconut fiber based activated carbon has been used for fabrication of supercapacitors. Iodine absorption test is performed to measured absorption level porous activated carbon sample size is relatively small (microporous). Characteristics of the activated carbon material covering the surface morphology and structure were tested using SEM and XRD. Electrode materials with composition (Activated charcoal: PVDF = 9: 1 (w / w)), the current collector and separator has been assembled to be tested its performance as an electrical charge storage device. The test results by cyclic voltammetry method was to look at the performance supercapacitor devices at once to obtain the value of the capacitance curve obtained voltammograms. Based on the results of the calculation of the capacitance, the highest capacitance values ​​obtained in the supercapacitor with activated carbon electrodes in coconut fiber steam 50 mL / bar with a capacitance value is 50.73 F / g.

Abstract

Laundry wastewater is generated in large quantities will pollute the environment such as rivers and soil if thrown away without any prior treatment. Laundry wastewater treatment methods that have been carried out are easy and inexpensive for household scale and have been proven to reduce levels of organic pollutants. Two parameters that can indicate the presence of organic pollutants in laundry wastewater are Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). This study aims to determine the effect of the use of filtration media in the form of a combination of activated carbon adsorbent, zeolite, silica sand, anthracite and ferolite in reducing levels of BOD and COD in laundry wastewater. Based on the results of laboratory tests on the BOD and COD test parameters, it was found that after the filtration process there was a decrease in the BOD and COD levels in the laundry wastewater samples respectively by 53% and 54%. The results of the statistical analysis also showed that the presence of filtration treatment had a significant effect in reducing levels of BOD and COD in laundry wastewater samples. Thus, it can be concluded that the presence of filtration treatment is proven to significantly reduce BOD and COD levels which can also indicate decreased levels of organic pollutants contained in laundry wastewater.

Abstract

Sintesis minyak diasilgliserol (DAG) dari crude palm oil (CPO) masih terkendala mahalnya harga enzim lipase komersial yang masih diimpor dari luar negeri. Telah dilakukan penelitian sintesis DAG menggunakan enzim lipase amobil yang dihasilkan dari kapang lokal Rhizopus oryzae dan diamobilisasi dalam butiran zeolit. Penelitian ini bertujuan untuk menentukan waktu gliserolsis enzimatis kontinu yang optimum dalam sintesis DAG; serta untuk menguji aktivitas dan stabilitas enzim lipase amobil dalam mengkatalisis gliserolisis enzimatis kontinu. Isolasi enzim lipase dilakukan melalui pengendapan dengan aseton serta diamobilisasi pada butiran zeolit. Sintesis DAG melalui gliserolisis enzimatis kontinu dilakukan dengan mengalirkan substrat secara kontinu ke dalam bioreaktor dengan berbagai variasi waktu dan penggantian substrat. Hasil penelitian menunjukkan bahwa DAG berhasil disintesis melalui gliserolisis enzimatis kontinu menggunakan enzim lipase amobil, dengan waktu gliserolisis optimum pada jam ke-21 dengan nilai konversi DAG sebesar 33 %. Adanya penggantian substrat ternyata membuat aktivitas dan stabilitas enzim lipase amobil cenderung semakin menurun.
