The use of synthetic dyes in food products are not good for health and the environment because there are carcinogenic materials need substitutes namely natural coloring. Rosella flower is one of the natural dyes that can be used on the peanut rocking product with the purpose to find out the color of the resulting component chemical compounds and sugar levels with the levels of acidity (pH) that is 1, 2, 3, 4, 5, 7 fixed and variable solution of extract Flowers Rosella (25 gr of powdered Flower 200 ml: Rosella water) and sugar solution (1 kg sugar : 1 Lt. water). The results showed that levels of acidity (pH) 1 and 2 have purple color; pH 3 pink; pH 4 pink faded; pH 5 and pH 7 is yellow and brownish pea shake products sugar levels generated 3.36% smaller compared to peanut products from the company amounting to rocking 3,38%. While the components of the chemical compound extract of flowers of rosella on the rocking nut products serve as food dyes also have efficacy as a medicine is Xhantosine, 5,5,7,7'- Tetrabromoindigo, Oleic acid, linoleic acid, chemical gamma-tecopherol, Vitamin E or alpha-tecopherol, Squalene.ABSTRAKPenggunaan pewarna sintetis pada produk makanan tidak baik bagi kesehatan dan lingkungan karena bersifat karsinogenik sehinga perlu bahan substitusi yaitu pewarna alami.

The increasing calorific value of brown coal using upgrading brown coal (UBC) method is generally conducted by heating it at the temperature of 150oC-160oC and the pressure of 350 kPa, in which the coal about to be processed is previously mixed with low sulfur wax residue (LSWR) as an additive substance diluted with kerosin. This research was aimed to know the effect of the heat temperature in UBC process which was done at the atmospheric pressure to increase the calorific value of the brown coal. One gram of brown coal was mixed with 0.5 mL LSWR dissolved in kerosin. The mixture was then heated using oven heater for 1 hour with the temperature variation of 100°C, 125°C, 150°C, 175°C, and 200°C. The results of the research show that the heating process at the temperature of 175°C produced coal with the highest increase caloric value e.g. 52,4%. The coal characteristic produced calorificc value was 5482 cal/g, water content was 3.138%, ash content was 6.009%, volatile matter was 66.288%, and fixed carbon was 24.565%.

Antanan are medicinal plants which contain alkaloids, saponins, steroids, terpenoids, carbohydrates, and reducing sugars. But, on the other hand, the use of them are rarely utilized. The purposes of this research were to determine the characteristics of antanan probiotic drink and examine the effectiveness of antanan probiotic as an antimicrobial for the Staphylococcus aureus and Escherichia coli. Steps of this research were the making of antanan probiotic drink with skim milk concentration variation treatment, characterization of the raw materials and antanan probiotic, and antimicrobial test of antanan probiotic. The results showed that antanan probiotic with a concentration of skim milk 5%, 7%, and 9% had a fat content of between 0.024% - 0.178%, protein content of 3.708% - 8,589%, ash content of 0.544% - 0.738%, and the total acid of 0.951% - 1.198%. These results were met with National Standard of Indonesia (SNI 2981:2009) about Yoghurt. The test results of antimicrobial activity showed that antanan probiotic can inhibit the growth of bacteria Staphylococcus aureus and Escherichia coli.ABSTRAKAntanan merupakan tanaman obat yang mengandung alkaloid, saponin, steroid, terpenoid, karbohidrat, dan gula pereduksi namun demikian pemanfaatannya masih belum banyak.

From the regulatory perspectives, pulp and paper mill sludge management as a environmental issue is significant. The restricted of imported recycle paper is a problem for the pulp and paper industry. Therefore a research was conducted to determine utilization potential of the WWTP sludge from paper industry in Indonesia as raw material for chipboard based on the characteristics of the sludge. The environmental aspects evaluation also has been cundected TCLP test and toxicology LD50 to determine whether the sludge waste category B3. The test results showed that the levels of alpha cellulose sludge is high (45-84%). Primary Sludge from virgin pulp contains high alpha cellulose (76-84%), ash content (3-14%), and the fines are quite low (30-34%). Potential of primary and final sludge to be used as raw material for chipboard. However, the primary sludge is generally recycled so that the final sludge are more preferable to be utilized. The results of FT-IR spectra analysis showed that the dominant chemical components in the sludge are cellulose. Fiber and fines content in line with the observation using SEM. Based on the results of the TCLP test and LD50, it is known that the sludge contains heavy metals, inorganic and organic are stable, so it is safe for the environment and can be utilized. Thus sludge has potential as a raw material for chipboard.ABSTRAKPengelolaan limbah sebagai isu lingkungan penting untuk dilakukan, terutama dari perspektif regulasi. Adanya larangan impor kertas daur ulang, merupakan masalah bagi industri pulp dan kertas. Oleh karena itu dilakukan penelitian untuk meneliti potensi pemanfaatan sludge IPAL dari industri kertas di Indonesia sebagai bahan baku pembuatan chipboard berdasarkan karakteristik sludge. Evaluasi terhadap aspek lingkungan berdasarkan uji karakteristik beracun TCLP dan uji toksikologi LD50 untuk mengetahui apakah sludge termasuk kategori limbah B3 juga dilakukan. Hasil uji menunjukkan bahwa kadar alfa selulosa sludge relatif cukup tinggi (45-84%). Sludge primer pulp virgin mengandung kadar alfa selulosa yang tinggi (76-84 %), kadar abu (3-14 %), dan kadar fines yang cukup rendah (30-34 %). Sludge primer maupun sludge final berpotensi untuk dimanfaatkan sebagai bahan baku pembuatan chipboard. Akan tetapi sludge primer pada umumnya didaur ulang sehingga sludge final lebih berpotensi untuk dimanfaatkan. Hasil analisa spektra FT-IR sludge menunjukkan bahwa komponen kimia yang dominan dalam sludge adalah selulosa. Data kandungan serat dan kandungan fines sejalan dengan pengamatan menggunakan SEM. Berdasarkan hasil uji TCLP dan LD50, diketahui bahwa sludge mengandung logam berat, inorganik dan organik yang bersifat stabil, sehingga aman terhadap lingkungan dan dapat dimanfaatkan. Dengan demikian sludge mempunyai potensi sebagai bahan baku pada industri karton chipboard. Kata kunci : Chipboard, industri kertas, LD50, sludge IPAL, TCLP

Chrome by product comes not only from elektroplating industry but also textile industry, leather tanning and laboratory waste. Looking at its existence and hazard, chrome by product has to further handled in order not to give negative effects to living creatures and environment. To avoid polluting the environment, the waste has to be processed first by lowering its content. One of the methods to reduce the content of the heavy metal is adsorption by using active bentonite as adsorbent. The purpose of this research is to find out the ability of active bentonite in reducting the content of chrome by product in waste. The procedure in this research consists of bentonite preparation, bentonite activation, content of chrome analysis in the raw material (waste water electroplating). The optimum treatment for the adsorption was at the mass of 25 gram stirred at 597 rpm with the contact time of 4 hours. Adsorption at the mass 25 grams could reduce chrome content from the initial chrome content waste water 394.59 mg/L to 194.34 mg/L with the reduction of chrome of 49.48%
