Abstract

Peningkatan jumlah produksi batik memberikan dampak terhadap lingkungan karena limbah cair yang dihasilkan selama proses pembuatan batik. Penggunaan air dalam proses pembuatan batik rata-rata 25-50 m3 per meter kain. Produksi batik di Indonesia sekitar 500 juta meter per tahun sehingga membutuhkan air 25 juta m3 yang setara dengan kebutuhan air bersih untuk 2500 rumah tangga. Persediaan air bersih tersebut menjadi limbah cair batik dengan volume yang besar, warna yang keruh, dan bau yang menyengat. Limbah cair batik memiliki kandungan pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), dan Total Suspended Solid (TSS) yang tinggi. Solusi yang diberikan untuk mengatasi permasalahan tersebut adalah(1) penyuluhan mengenai kandungan kimia, dampak dan bahaya limbah industri batik terhadap ligkungan dan kehidupan manusia di sekitar kawasan industri, (2) penyuluhan/sosialisasi metode-metode yang dapat diaplikasikan untuk menangani limbah industri batik, (3) Penyuluhan/sosialisasi penggunaan dan perawatan teknologi tepat guna mesin pengolah limbah batik sebagai solusi mengurangi pencemaran limbah batik pada lingkungan hidup, (4) penyerahan teknologi tepat guna berupa green technology alat pengelolaan limbah batik.

Abstract

The issue of heavy metal pollution is a significant concern in the environmental. Hexavalent chromium (Cr(VI)) is hazardous heavy metal when it is discharged and expands within ecosystem. Cr(VI) is a hazardous compound that high susceptibility to oxidation and mutagenic. The tannery industry generates hexavalent chromium in its liquid waste. Managing Cr(VI) liquid waste could use the adsorption technique with activated carbon. In this study the activation of activated carbon using microwave-assisted ZnCl2 chemical activation. The activated carbon used for adsorbing the Cr(VI). The objective of this study was to ascertain the optimum parameters for the adsorption of Cr(VI) utilizing activated carbon. The optimization method is Taguchi, which incorporates three factors: A (pH), B (activated carbon dosage), and C (agitation). The result of optimization is pH 2; 0,4 g activated carbon dosage, and agitation 20 rpm, which the optimal response was 16.7498 mg/L. The analysis using the desirability obtained desirability value of 1. The ANOVA results indicate that the pH significant on the response. The adjusted R-square is 0.9667 and predicted R-square is 0.8668. It can be concluded that the model and actual conditions has slighly discrepancies. Then, the regression equation from the model can be estimate the actual value.

Abstract

Tanning industry is one of the industries that produces tannery waste water (TWW) which is dangerous to the environment. About 250 kg leather generating 15,000-50,000 of waste water. This increase environmental concerns regarding TWW. In this review, discussed the concept cleaner production (CP) approach at each process stage in the tannery process and the Zero liquid discharge (ZLD) system used in processing tannery liquid waste. The application of CP in the leather tanning industry is by substituting chemicals with environmentally friendly materials, management water, optimizing tanning conditions, and using technology to recycle and reuse liquid waste. The application of the ZLD system is one of the CP approach for recycle and reuse TWW. The ZLD system used in leather tanning is the Thermal-based ZLD system and Reverse Osmosis. Several countries have implemented the ZLD system, are the United States, India, China, European Union countries and Middle East. The ZLD system is an important TWW strategy to be implemented globally, although operating costs and high energy consumption are limitations in its application. Technological advances and exploration of new approaches to overcome the limitations of ZLD technology may make the approach more feasible and sustainable in the future.

Abstract

In this research, the extraction of essential oil from fresh basil leaves using solvent-free microwave extraction (SFME)and microwave hydrodistillation (MHD) method. Several parameters influence the extraction of basil oil using SFME method: microwave power, the ratio between the mass of raw material with a volume of distiller (F/D), material size, and length of extraction time. Besides, the components contained in basil oil and changes in oil gland conditions in basil leaves before and after being extracted were also evaluated. The optimum condition was obtained as follows: microwave power of 380 W, the ratio between the mass of raw material with a volume of distiller (F/D) of 0.1 g/mL, raw material size of intact (± 3 cm), with an extraction time of 60 min. Moreover, SFME has a shorter extraction time to produce yields than MHD methods. GC-MS analyzed the composition of basil oil, and there were 49 identified components. This study shows that SFME method more effective than the MHD method for extraction basil oil from fresh leaves based on time extraction and yield.

Abstract

Bioethanol is a form of renewable energy that is used to reduce dependence on the use of fossil fuels which cause various negative impacts on the environment. Ulva sp. contains high carbohydrates so it has the potential as a raw material for bioethanol production. This study aims to determine the optimum conditions of the fermentation process with the variables used time, pH, and yeast concentration. This study used the results of hydrolysis of Ulva sp. with optimum operating conditions of 0.1 N HCl concentration, 80 mesh particle size, and 450 watt microwave power. Measurement of bioethanol levels was carried out using an alcoholmeter. The results showed that the optimal conditions for fermentation were 7 days of fermentation, pH 5.5, and yeast concentration of 1.5% which resulted in a bioethanol content of 7.55%.

Abstract

The Pegagan plant has a scientific name in the form of Centella asiatica L. which is included in the Centella genus, Apiaceae family, and kingdom Plantae. Pegagan (Centella asiatica L.) has distinctive bioactive components, namely triterpene ester glycoside compounds in the form of asiaticoside and madecassoside, and triterpene group compounds in the form of Asiatic acid and madecassic acid. In this study, the extraction of bioactive components from pegagan was carried out using the Microwave-Assisted Extraction (MAE) method and will study the effect of ethanol solvent concentration in the extraction of bioactive compounds. Analysis of the extracted bioactive content was carried out by analyzing the total phenol content using the Folin-Ciocalteau reagent and ANOVA analysis. The results obtained from the study were in the form of total phenol content as an indication of the presence of bioactive compounds, namely at operating conditions of 450 watts of power, 50% ethanol concentration with a radiation time of 15 minutes which resulted in a total phenol content of 21.9244 mg AGE/g sample. In the ANOVA analysis with ethanol solvent, variables that gave a significant response to the total phenol content were microwave power, radiation time, and ethanol concentration with an R-square value of 95.31%. The effect of ethanol concentration on the total phenol content produced, namely the concentration of pure ethanol solvent will produce extracts with the smallest total phenol content, the effect of extraction time on total phenol content, namely the longer extraction time will increase the total phenol content. Maximum total phenol content using ethanol solvent that is, at operating conditions of 450 watts of power, 10% ethanol concentration with a radiation time of 15 minutes which resulted in a total phenol content of 520 mg AGE/g sample.
