Abstract

Heavy metal waste many there is in a few waste industry chemistry, for example at industry electroplating,metallurgy, smelting and others. At waste industry electroplating contains copper heavy metal and chromium which can cause contamination if thrown exceed boundary threshold enabled.This research method started with grows mushroom Phanerochaete Chyrsosporium in liquid medium with composition of peptone 20 gr/ltd an 40 gr/lt glucose incubation at temperature 350C during 6 day. Step of hereinafter is take 200 ml waste which concentration of Cu 2+ 5,7 mg/ltd an concentration of Cr6+ 137 mg/lt and hydrogen ion exponent 3,15 . Waste is boosted up its(the hydrogen ion exponent becomes 5 with nitration NaOH 0,1N 93,9 ml then is added with adsorbent 10,20,30,40 and 50 ml and incubation during 90,120,150,180 and 210 minutes. Then solution filtered and filtrate is analysed with spectrophotometer.Result of research is obtained [by] best condition at adsorbent volume 50 ml and adsorption time 210 minutes concentration of Cu2+ : 0,414 mg/lt and concentration of Cr6+ be 0,381 mg/lt.  Keyword :Biosorpsi, Phanerochaete Chrysosporium

Abstract

Mengkudu represent all purppose crop, a lot of type of amendable product from root, bar, leaf, and also its fruit.At fruit mengkudu have content of carbohydrate as much 51,67 gr. With obstetrical existence the carbohydrate enable to be exploited permanent upon which produce ethanol. Intention of this research is determine condition of best process making of ethanol with raw material of fruit mengkudu.Ethanol yielded to be obtained heatedly of fruit mengkudu liquid by HCL 0,4 N in neck gourd three as hydrolysis process, so that got the sugar rate equal to 8,23%. Hereinafter, can be made ferment media from sugar liquid result of hydrolysis enhanced by a starter volume at spanning : 4- 12%. Later;then ferment as according to variation time of between 24 - 72 clock. Liquid of result of the ferment dissociated by distilatation, temperature taken care of 80ºC.Result of biggest ethanol obtained when ferment 60 clock, addition of volume starter 10% with ethanol rate = 6,24 %.Keyword : Ferment , Hydrolysis, mengkudu , Saccharomyces Cerevisiae, Ethano

Abstract

Availability of bulrush can be obtained by continue and abundance, representing one the less exploited crop.Bulrush only used as livestock food, sometimes bulrush also considered to be intruder crop. But bulrush have cellulose rate, glucose, extract able to be used as one the ethanol producer materials. Obtained Ethanol rate from study produce bio ethanol from bulrush between 23-28 %, to increase purity of ethanol rate conducted bydissociation use batch distillation. Research produces bio ethanol from bulrush chemically to look for bio ethanol alternative raw material and study sour hydrolysis process and fermentation. In research produce bio ethanol from bulrush chemically to process hydrolysis at condition remains to: temperature 30oC, water 7 liters,hydrolysis time 1hour and condition change: bulrush weight 50, 100, 150, 200, 250, 300 (gram), HCL condensation volume 10, 20, 30, 40, 50(ml). Is then continued by fermentation process at condition remain to:temperature 30oC, pH 4.5; fermentation volume 500 ml and condition change: fermentation time 4, 5, 6, 7, 8(day), starter 8 %, 10 %, 12 %. From research produces bio ethanol from bulrush chemically obtained [by] result, [at] best glucose rate hydrolysis process 26.29 %, bulrush weight 200 gram. At best condition ferment process use saccharomyces cerevisiae starter 10 % during 6 day, yielding ethanol equal to 27.71 % and glucose rate is rest of 8.09 %. To obtain get purity ethanol product to process separation of continuation with batch distillation, after conducted separation continue to be obtained ethanol rate (90-95) %. From result is obtained that is ethanol rate (90-95) %, bulrush can be used as alternative raw material making of bio ethanol. But for the standard of bio ethanol that is ethanol rate above 98 %, so that require to furthermore process.  Keyword: bio ethanol, fermentation, hydrolysis, purification, bulrush

Abstract

Availibility of world fossil energi will continue scarce and progressively costly. The situation will affect to sugar production cost, specially at SF which still insuffiency of bagasse and burn oil. Insuffiency of bagasse in SF righteously can overcome because sugar cane have enough bagasse content for boiler fuel, with balance installation, efficient equipments, amount and quality of sugar cane milled which is adequate, hence in SF can be obtained excess of bagasse or energy which is useful for raw material of industry.Key words :Energy crisis, sugar factory (SF), cane bagasse, steam generation, steam use, energy efficiency.

Abstract

Saat ini dunia mengalami krisis energi yang berasal dari sumber tak terbaharukan, tidak terkecuali Indonesia. Sehingga perlu suatu upaya untuk mencari sumber energi alternatif dari sumber yang terbaharukan. Salah satu sumber energi alternatif yaitu biodiesel yang dapat diperoleh dari sumber nabati yaitu kelapa sawit, kedelai, jarak, nyamplung ataupun tumbuhan yang lainnya. Peningkatan produksi biodiesel diikuti dengan meningkatnya produk samping biodiesel yaitu gliserol. Penelitian ini bertujuan mempelajari konversi gliserol secara batch menggunakan gelombang mikro yaitu dengan melihat pengaruh daya dan waktu pemanasan microwave terhadap yield produk cair yang dihasilkan. Larutan gliserol dengan rasio massa gliserol terhadap air 1:9 dimasukkan pada reaktor yang terbuat dari gelas. Reaktor ditempatkan pada microwave oven dengan power dan waktu pemanasan tertentu. Produk liquida yang dihasilkan dianalisa dengan GC dan GC-MS. Produk konversi gliserol adalah allil alkohol, metanol, serta beberapa produk yang tidak teridentifikasi. Semakin besar daya microwave semakin besar yield etanol yang didapatkan, demikian pula semakin lama waktu pemanasan microwave semakin besar yield etanol yang diperoleh. Yield etanol yang paling besar pada daya 600 W, selama 15 menit yaitu sebesar 6,764%.Kata Kunci: Degradasi Gliserol, Gelombang mikro

Abstract

Photokimia have used as by many alternative processing of water. Photokimia reaction is reaction of chemistry which is induction by light either trough indirect and also direct. Conversion ofr Energy light become chemical energy or electrics represent elementary principle of photokimia. To quicken reaction of conversion needed by the existence of catalis reffered as catalis system. Catalis will be active if obtaining light energy. In course of fotokimia will be formed by radical hydroxyl to degrade compound of organic underwater of waste like surfactant. The research dergradation of concentration surfactant used Titanium Dioxide catalis with light source the used is lamp of UV which variation of 15 watt, 30 watt and 36 watt. The objective of research to determine abilitry degradation of concentration of surfactant in waste of detergent. Result of research indicate that ability of degradation of be concentration use TiO2 counted 2,2 gr with result 96,5 %, time of radiating 2,5 hour and lamp energy 36 watt. Key words :Photokimia, Photokatalitik, Surfactan
