Research about treatment of waste water from activity of Exploration and production oil and Gas with comprehensive solution method (bioremediation-biotreatment-biofiltration) has been done. Purpose of this research is to knows the bacterium activity in reducing rate cemaran petroleum liquid waste.. first phase added bioremiaddiasi with addition of biological agent which has been obtained. At this phas added bacterium counted 6% v/v from waste water volume and growth of bacterium is optimal. Second phase is biotreament that is by giving opportunity of bacterium which has been added so that initiation of floc formation. At this phase liquid waste is flown showly and is not aerated so that s formed flok initiation by bacterium, and than phase three is biofiltration by flowing waste to bioreactorending containing active carnonl. The active carbon has contained bacterium at part of the surface so that liquid waste passingit will experience biofiltration. The three steps can process waste soThat so parameter qualified that is H²S,Fenol,COD,Oil fatty, and ammonia declines so is under theasthold with quicker time.To know method effectiveness of comprehensive solution is done waste treatment of microcosm scale to apply biological agent obtained.. This thing was showed result of examination of control microcosm from sampling T0 until T8 is H2S:0.144-0,015 mg/l,phenol 1,6537-0,405 mg/l,hydrogen ion exponent 9,07-9,13,COD g372-1132 mg/l, oil lemak52-471 mg/l and ammonia 3,713-0,1373 mg/l of chemical test result at microcosm with method coprehensive solution is H2S: 0,160-0,014 mg/l,phenol 0,0529-0,0105mg/l,hydrogent ion exponent 9,07-9,13,COD 9372-1132 mg/l, oil lemak 52 -471 mg/l and ammonia 3,713-0,1373 mg/l.Based on calculaton of linear regresision to degradation of parameter tasted waste at microcosm with method comprehensive solution is estimated to requires processing time around 41 days, almost thrice more effectively if using ordinary IPAL method

The objective of this research was to study the effect of temperature and time depolymerization of natural latex rubber using NaNO2, H2O2 and Ascorbic Acid (0.4: 0.2: 0.1) mol at pH about 5 towards its molecular weight reduction, then studied the effect on the quality of adhesives produced. The stages of this research include making concentrated natural rubber latex, its depolymerization, rubber crepe making, rubber compounding and followed by rubber adhesives manufacturing. Depolymerization is conducted by varying the temperature (50, 70 and 90 oC) with the duration (4, 6, 8, and 10 hours). The indication of molecular weight reduction is determined by the mooney viscosity test, while the quality of the rubber adhesives is evaluated from the Brookfield viscosity test and its peel strength. Concentrated Natural Rubber was successfully prepared using 2% (v / v) ammonium laurate 20% and 0.2% (v / v) 2% sodium alginate resulted in dry rubber content 49.36%, mechanical stability 91 seconds, ammonia 0.58% and Viscosity Mooney 193.80 cp. Chemical depolymerization is able to reduce the viscosity mooney of natural rubber approximately 95%. The results showed that the greatest molecular weight reduction was depolymerization at 70 ° C for 8 hours indicated by decreasing the mooney viscosity from 193.80 to 10.05 cp. From the results of testing the quality of the adhesives, the lower the molecular weight the adhesive power between layers of rubber is higher with lower Viscosity Brookfield. The peel strength of resulted adhesive ranges from 4.76 - 17.25 kg / inch2 with brookfield viscosity between 1966 - 3810 cp. Based on the comparison with the quality of rubber adhesives in the market that has peel strength about 4.35 kg / inch2, it can be said that the rubber adhesives from of this research results have met the market requirements.

Research about the effects of dextrin addition on the quality of coffee cube has been conducted. This research aims to know the effects of dextrin on the quality of block coffee. Full random design is used with ten treatments consisting of D0 (control) without dextrin, D1(0.5% dextrin), D2(1%), D3(1.5%), D4(2%), D5(2.5%), D6(3%), D7(3.5%), D8(4%), D9(4.5%),D10(5%), all treatments are repeated three times. The observed parameters include pH of the prepared coffee, moisture content, extra content, hardness of coffee and organoleptic test of prepared coffee taste. The result of this research shows that the treatment has significant effect on moisture content, extra content, pH of the prepared coffee, the solubility, hardness and taste of coffee. Characteristics of block coffee with 0-3% dextrin addition produce moisture content in range of 6.31% to 6.60%, extract content in range of 29.41% to 59.72%, pH of prepared coffee in range 5.62% to 5.806%, solubility in range of 43.80% to 60.1%, and hardness of coffee in range of 0.21% to 0.59%. For organoleptic test on the taste of prepared coffee in treatments of D0 to D6, there is no significant effect on the taste of coffee while for treatments of D7 to D9 have significant effect. Dextrin addition under 3% does not have effect on the taste of coffee but dextrin addition above 3% will affect the taste of coffee.
