Malachite green is a synthetic dye that is widely used in the textile industry. Textile industry waste that is not treated properly will pollute the aquatic environment. The threshold value for the permissible concentration of Malachite green in waters is around 0.01 mg/L. The adsorption method is an alternative method used to remove dyestuff waste. This study used a batch method which aims to determine the optimum conditions for absorption and the maximum absorption capacity of Malachite green using activated carbon from the peel of Kepok banana (Musa balbisiana Colla). In this study, treatments were carried out using variations in solution concentration and contact time. The results of this study, obtained the absorption capacity at optimum conditions concentration 150 mg/L and contact time 150 minutes with absorption capacity of 9.2429 mg /g with absorption percentage of 97.9734%. Mechanism the absorption of Malachite green follows the equation Langmuir isotherm with a determinant coefficient (R2) of 0,9989.

Telah dilakukan penelitian tentang efektifitas Al(OH)3 sebagai coprecipitant pada penentuan kadar logam kadmium dalam air sungai Batang Arau menggunakan Spektrofotometri Serapan Atom (SSA). Penelitian dilakukan dua tahap, pertama penentuan kondisi optimum dan kedua aplikasi kondisi optimum pada sampel air sungai. Kondisi optimum coprecipitant yang didapat setelah pengukuran dengan SSA yaitu pada pH 7 dan volume Al3+ 0,2 M 11 mL. Kandungan kadmium dalam sampel air sungai Batang Arau dengan kopresipitasi pada bagian hulu 0,3385 mg/L, tengah 0,34625 mg/L dan hilir 0,3575 mg/L, sedangkan tanpa kopresipitasi -0,039 mg/L, -0,028 mg/L, -0,049 mg/L. Hasil ini menunjukkan bahwa coprecipitant Al(OH)3 dapat digunakan untuk mendeteksi trace metal dalam suatu sampel.

The malachite green dye is one of the harmful dyes produced from various textile industry wastes and needs to reduce by the presence of the waste. The biosorption method is one of the alternative methods used to remove the concentration of malachite green. Biosorption using langsat peel biosorbent proved to be able to absorb malachite green dye. This study using the coloum method by varying the pH of the MG solution and particle size of the biosorbent. In this research, spectronics were used to measure the concentration of the solution and analyze the functional groups on langsat peel before activation, after activation, and after contact using FTIR. Based on the results of the study, it was found that the optimum conditions for each variation were at solution pH 5 with an adsorption rate of 4.962 mg/g and particle size of biosorbent 106 m with an adsorption rate of 15.376 mg/g.

Methylene blue is one of the textile industry wastes which can cause pollution to aquatic ecosystems. The threshold value for the permissible concentration of methylene blue in ambient waters (5-10) mg / L. So we need a method to treat wastewater contaminated with dye so that it is safe to dispose of and does not pollute the environment. One of the effective methods for removing dye waste is the adsorption method. The purpose of this study was to determine the optimum absorption conditions and maximum absorption capacity of methylene blue using activated carbon from the peel of a banana (Musa balbisiana Colla). In this study, using the Bacht method to adsorb methylene blue dye by varying the pH and stirring speed. The results of this study showed that the absorption capacity at the optimum conditions of pH 6 and a particle size of 250 µm was 5.4096 mg / g and the absorption percentage was 86.54%.

Composite bacterial cellulose - seaweed (BC-SW) was prepared by immersing the bacterial cellulose (BC) in seaweed extract (SW) for 1,2,3, and 4 days. Has researched the effect of immersion time on the physical and mechanical properties of the composite, the result showed that longer of immersion time decreases the water content, the higher the compressive strength, tensile strength and elasticity BC-SW composite. From the research done, the content of BC reached 99 156% while for BC-SW composite decreased water content of up to 98 585%. In the compressive strength test, the compressive strength of BC is 0292 MPa, while the BC-SW composite the compressive strength increased 2 times to 8 times stronger than BC. The value of physical and mechanical properties have not been suitable with the standards for the manufacture of cartilage. Analysis of the structure of KSB-RL was observed using FTIR and XRD. Results of FTIR spectra showed no new functional groups but only experienced a slight shift in the vibrational wave numbers.

Activated carbon from durian peel is synthesized by chemical activation using an alkaline sodium hydroxide. The carbonization process is carried out for 2 hours at a temperature of 320ºC. Activated carbon is characterized by conducting several quality tests based on SNI 06-3730-1995 which has met all specified standards. The results of the FTIR spectrum show that activated carbon has a cluster of -OH at wave numbers 3000-3400 cm-1, C = C at wave numbers 1540-1630 cm-1, C-O in wave numbers 1150-1275 cm-1.
