Abstract

Indonesia is one of the country that proposed as a country tag has the world's largest peat, whilethe carbon content in peat is quite high, namely ± 60%. To increase the economical value of peat in amanner that is processed into activated carbon. This research aims to make activated carbon from thepeat soil and nutrient concentrations studied the influence of activators and activation times for the qualityactivated carbon produced. Raw materials used to make activated carbon is peat derived from centralKalimantan. H2SO4 solution is used as the activator. While Iod solution, a solution of potassium iodideand thiosulphate solution 0.1 N is used as active carbon absorbent testing agent. Set of variables: 550 0Ctemperature carbonization, carbonization time of 2 hours, peat, coal 40 mesh particle size , weight of 100grams of active carbon, the comparison of the char activator 1: 10 and the drying temperature is 120 0C.Carried out activator concentration are 5%, 10%, 15%, 20% and 25% and time of immersion / activationare 1, 1.5, 2, 2.5, 3 (h). Research results are measured from the active carbon absorbent rate of Iodinesolution. Best results absorbed rate measured as 21.88% were obtained in 20% H2SO4 concentration andactivation time of 2.5 hours.Key words: active carbon, peat, activator, carbonization, absorbent rate

Abstract

This research aims to study the effect of liquid flow rate and bed height on mass transfer coefficient in theadsorption of detergent in water using activated carbon adsorbent in the fluidized bed column. Theexperiment was preceded by an orifice meter calibration and manufacture of detergent solution in water atvarious concentrations. Detergent solution was then fed into the tank inffluen on fluidized bed column andflowed into the column at various flow rates and higt of bed. Effluent from each variation of measuredconcentrations and calculated % detergent absorbed and mass transfer coefficient.The results showed that increasing the flow rate increases the amount of detergent liquid is absorbed andthe mass transfer coefficient. For high-bed 10, 20 and 30 cm, the higher the bed the higher the amount ofdetergent to be absorbed and the mass transfer coefficient. % Detergent which absorbed the highestachieved at influent concentrations of MBAS concentration of 0.054 mg / lt, and 30 cm bed height that isequal to 25.9%. The the highest mass transfer coefficient is 9,457.10-6cm / dt2 on influent concentrationMBAS concentration of 0.054 mg / l and 30 cm bed height.Key word: detergent, activated carbon, % detergent adsorbed, fluidization, mass transfer coeffisien

Abstract

The baffle influence to the degree of liquid mixing in the plate and the pressure drop on the plate has beenstudied in this research. The operational pressure in this research is limited in the atmospheric pressure .Thedistillation column that used in the research has 0.2m diameter and 1.4 m height with the distance betweentrays is 0.4 m. The research was carried out by to flows water into the column with the flow rate of water are105 l/h, 149 l/h, 189 l/h and to flows air into the lower of the column with superficial speed from 0 to 0.3 m/s.After steady state is required the dry plate pressure and the pressure drop because the difference between theheight of clear liquid and the height of foam is measured. The mixing degree is determined by stimulusresponse method, i.e flows air into the system, then give a tracer (i.e. NaCl saturated 20 CC) as a stimulatorthat injected into the fuild to the basin. This experiment will give the data off the concentrations and the time.The conclusion of this research is the pressure drop by dry plate can provide the correlation hD = 8.34926( )( ) Lh GgUρρ22. The value of residual pressure drop at the column of sieve plate without baffle and with use abaffle in this study almost constant, i.e. 1-2 mm H2O. The relation among the Peclet number, the F factor andthe flow rate of water can expresse in empirical equation are : for without baffle Pe = 0.3837 F0.9254 Q-0.05229;Baffle V, Pe = 0.00005306 F-2.341 Q-1.005; vertical Baffle Pe = 0.004989 F-1.775 Q-0.4848. The presentation of thedifference of the clear liquid’s height in the condition without use a baffle are 86,88% for the V baffle,53,55% for the vertical baffle (105 l/h); 73,5% for V baffle, 50,64% for the vertical baffle (149 l/h); 84,34 forV baffle, 65,58% for vertical baffle (189 l/h). The value of EMV / EOG for the experiment without use a baffle isgreater than the value of EMV / EOG fot the experiment use a baffle.

Abstract

The existence of Biodiesel as an alternative fuel from year to year has decreased quantity and will become lessand less because of rising demand. One source of biodiesel raw materials are seeds Avocadot.Seeds Avocadois still not utilized for other products, and avocado seeds contain fatty acid methyl esters of 71.715% asmaterial for biodiesel. The aim of this research is to make biodiesel from avocado seed oil so it can be used asalternative diesel fuels and also take advantage of avocado seed in order to have a high value in order to beprocessed into biodiesel. Operating conditions used was 10 ml volume of oil, transesterification temperature ±60 ° C, NaOH to oil weight ratio of 1% and stirring speed 600rpm. Also, studies conducted on the oil to methanolmole ratio 1:4, 1:6, 1:8, 1:10, 1:12 and with a variation of 5, 20, 35, 50 and 65 minutes. Peneliatianresults show that biodiesel meets the standard avocado seed oil as an alternative fuel in Indonesia because ithas a value of flash point between 130 ° C to 240 ° C and has a pour point value between -2 ° C to 9 ° C.Keywords: Seeds of avocado, transesterification, biodiesel.

Glucose is a monosaccharide that is widely available in fruits, and plants obtained throughthe hydrolysis of starch saccharides using enzymes. Sweet potato starch hydrolysis is run by threeneckflask equipped with a stirrer. At stage Liquifikasi, three neck flask inserted into a solution ofstarch which has been set temperature and pH plus HCI and heated, then added α-amylase enzymein a certain time.Saccharification second stage, where the results liquifikasi cooled, set thetemperature and pH on certain conditions. Giukoamilase enzyme is then added to the volumeaccording to the specified variable, and incubated at a given time. At a certain time interval wastaken a few examples of the analyzed samples to be analyzed glucose levels. Process behaviorobserved in this study were changes in temperature, hydrolysis time and the addition of enzymes,the best hydrolysis results obtained at 60 0C, pH 4.5 and the addition of the enzyme glucoamylase,07 ml and the time hidrilisis 5 days with glucose levels reaching 5.65% and conversion yield of66.8% and 22.59%.Key words: Sweet Potato Starch, Liquifikasi, sakrifikasi, glucose

Abstract

With the increase in the development of technology, then today often products from a factorythat various forms in the market in order to satisfies the consumer. For example was the number of soapproducts that emerged. Because of that as the new alternative that is looking for the alternative base forthe production base of soap. The alternative that will be developed was the production of soap from thatis fat. This research was to make laundry detergent by making use of the waste of the skin industry. Wasbased on results of the analysis it was known the best condition was achieved at the time of the increase7 gram and the increase KOH 15 gram with the level of free alkali 0.094 %, fat not 1.80 %, and thenumber fatty acid 68.7 %. Meaning that at the moment the condition for the quality of laundry detergentbased on the Standard of Nasional Indonesia could be filled.Key words: solid waste , skin industry,KOH, fatty acid, soap.
