Abstract

The use of dyes from natural materials have long been used, but with the discovery of synthetic dyes are relatively easily produced and have better stability, natural dyes began to be abandoned. But it turns out the use of synthetic dyes have a negative impact on the environment and human health. One of the natural resources that have the potential for henna plant dye is water. Henna plant parts water can be used as natural dyes are the leaves that allegedly contain anthocyanins. To concentrate the dye obtained use of additives of gambier. This study aimed to study the effect of the solvent, the stability of the natural dyes to the effects of environmental conditions, and absorption of natural dyes produced in the coloring of textile materials. The solvents used are ethanol + water, ethanol and acetone. The results showed that the natural dye textiles manufacture of henna leaves water (Impatiens balsamina Linn) at the highest dye produced by ethanol. Value% yield produced by ethanol is 37.3788%.

Abstract

Sengon wood (Albizia falcataria) is chosen as an alternative raw material for the manufacture of pulp has physical and chemical characteristic that meet the standards of raw material for pulp. The most important factors that influence the process of the kraft pulping is the ratio of the cooking liquid (AA charge) which serves to degrade and dissolve so easy to separate lignin from cellulose, while still protecting carbohydrates from degradation so that the resulting yield and good physical strengt. The study began with the preparation of raw materials, cooking by using a variable charge AA 14%, 16%, 18%, 20% and 22%, pulp washing and sheet formation, as well as the analysis of the quality of the pulp. Cooking liquid ratio will affect the yield and quality of pulp, including kappa number, viscosity and brightness. The low use of cooking liquid causes the higher lignin content in pulp and produce wood that is not mature, so the higher the yield, kappa number and viscosity, but lower brightness. While conversely, the higher the cooking liquid use causes more fiber degraded.

Abstract

Dried noodles is one of favorite food in Indonesia because it’s simple and easy to cook. The use of corn flour as substitute for making noodles is an effort to diversify food in reducing the import of wheat flour. The objective of this study was to determine the optimum drying conditions to obtain the best quallity of dried noodles, with ratio composition of corn flour and wheat flour 2:3. This study used completely randomized design with temperature and time drying. Drying was conducted using a tray dryer at various temperature (60, 70, and 80oC) and various time drying (60, 70, 80 and 90 minutes). The observed quality parameters were water content, ash content and protein content. The result showed that the optimum drying condition is 80oC and 90 minutes long with water content 6,87%, ash content 1,78%, and protein content 19,39% and the result of the coefisient of drying rate (k) is 0,1218

Abstract

Politeknik Kampar merupakan salah satu politeknik yang mempunyai laboratorium miniplan pengolahan CPO menjadi minyak goreng, biodisel dan sabun. Pada saat operasinya pengolahan ini menghasilkan limbah cair dan limbah padat. Limbah cair yang dikeluarkan oleh suatu sistem pengolahan harus dilakukan pengolahan sebelum dibuang kelingkungan. Berdasarkan percobaan yang dilakukan proses yang menghasilkan limbah adalah pada proses degumming dihasilkan air limbah sebesar 159 L per 1 kali proses dilakukan, dimana air limbah ini mengandung gum dan berwarna kuning. Pada proses netralisasi menghasilkan limbah padat yang mengandung soapstock sebesar 10,93 kg limbah per 1 kali proses dilakukan. Limbah padat ini dapat dijadikan bahan baku sabun dengan bilangan penyabunan sebesar 480,7 mgram KOH/1 gram zat uji. Air limbah yang dihasilkan dilakukan uji jartest di laboratorium menggunakan koagulan PAC (poly alumunium clorida) dan flokulan aqua clear. Berdasarkan percobaan uji jartest yang dilakukan didapat kualitas air hasil olahan sudah berada dibawah ambang batas lingkungan baik pH, warna maupun tingkat kekeruhan. Dosis ekonomis koagulan PAC adalah pada penambahan 60 g/L dan dosis aqua clear yang dibutuhkan adalah sebesar 1,2 g/L per 1 kali proses dilakukan. dilakukan pengecekan kadar COD pada air limbah, dari hasil laboratorium didapat kadar COD akhir sebesar 444,9280ppm dan efesiensi penurunan COD sebesar 63,41%. Berdasarkan hasil laboratorium dibuat perancangan unit-unit pengolahan limbah, didesain bak equalisasi, koagulasi, flokulasi dan sedimentasi. Pada penelitian ini perancangan dilakukan untuk bak sedimentasi yakni panjang 1,50m, lebar 3,20m dan tinggi 3,20m dan bak pembubuh dengan pertimbangan sudah memenuhi volume limbah cair yang diolah.

Abstract

At the Sari Mukti Landfill, the reduction in the volume of waste entering the final processing is achieved through landfill management, composting, and sorting. The sorting that has been carried out so far is done by scavengers. Based on data and studies conducted at the landfill, it was concluded that the sorting efficiency, on average, between January and February is 0.81%. This efficiency of 0.81% was obtained from sorting in 5% of zones B and C, with a total of 385 scavengers. If we apply the same efficiency to 100% of the area, the number of scavengers required would be 7,700. However, the results of the study do not recommend increasing the number of scavengers. Instead, it is recommended to sort waste at the source. With the sorting mechanisms outlined in the discussion, it is hoped that only a small portion of organic waste will enter the landfill.

Abstract

Activated carbon can be synthesized from lignocellulosic biomass, such as kepok banana (Musa paradisiaca) stems, which are an abundant agricultural waste rich in cellulose (~64%). In this study, kepok banana stems were utilized as a precursor to produce activated carbon using hydrochloric acid (HCl) as the chemical activating agent. The activation process employed HCl concentrations of 1.5, 2.0, 3.0, 5.0, and 7.0 N, with a carbonization temperature of 400 °C for 1 hour and an Fe adsorption contact time of 30 minutes. The resulting activated carbon was evaluated based on its physicochemical properties according to the Indonesian National Standard (SNI 06-3730-1995). The sample treated with 3.0 N HCl showed optimal characteristics, including moisture content of 2.34%, ash content of 0.28%, volatile matter content of 2.05%, and fixed carbon content of 95.33%. Its iodine number reached 1116.98 mg/g, and the Fe ion removal efficiency was 99.14%. FTIR spectroscopy confirmed the presence of functional groups typical of activated carbon—O–H, aromatic C=C, C–H, and C–O—suggesting good adsorption potential. Furthermore, adsorption behavior was analyzed using the Freundlich isotherm model, which describes multilayer adsorption on heterogeneous surfaces. The findings demonstrate that activated carbon derived from kepok banana stems is an effective, low-cost, and environmentally friendly adsorbent for iron removal, suitable for applications in water purification and wastewater treatment.

Abstract

PT. Aneka Tambang conducts gold processing using NaCN reagents, then from the gold processing process produces waste containing cyanide which can cause damage to the environment. One method used to reduce cyanide concentrations is the Degussa method. The Degussa method is a method to degrade free cyanide in waste by using H2O2 and Cu2+ ions as a catalyst source so that it becomes a harmless cyanide compound (cyanate ion). The purpose of the study was to determine the ability of hydrogen peroxide and determine the effective concentration of copper sulfate in degrading cyanide in the Degussa process and determine the level of stability of hydrogen peroxide oxidizers in the open air. Sample testing was carried out by varying the H2O2 retrieval time, variations in H2O2 dilution factor and copper sulfate concentration variations, then the sample was stirred with a jartes stirrer for 15 minutes. Cyanide is determined by spectrophotometer, the absorbance obtained is fed into the linear regression equation so that the final free cyanide concentration is obtained. From the experiment, it can be concluded that the concentration of cyanide degradation is effectively obtained when hydrogen peroxide and copper sulfate that have been mixed in the mixing tank are right out of use.
