OPTIMASI PARAMETER PROSES PEMBUATAN BIOETANOL SORGUM DAN PENGARUH TERHADAP UNJUK KERJA MOTOR BENSIN

Bioethanol is a renewable fuel that resembles gasoline, bioethanol is produced from fermentation and distillation processes. One of the raw materials that produce bioethanol is Sorghum. Sorghum was chosen because it is superior to other plants. This study aims to analyze fermentation longtime and enzyme composition for the best composition to produce bioethanol from sorghum, and determine the quality of sorghum bioethanol. This research Sorghum bioethanol produced with an alcohol content of 94%. The test and analysis variables used were 31 samples. The results of this study are as follows : The best fermentation time is 4 days, the enzyme and yeast variable for the most volume of alcohol is 7% yeast 5% enzyme, the enzyme and yeast variable for the highest alcohol content is 7% yeast 7% enzyme. Laboratory test results when compared with PERTAMINA's standard regulations, especially Pertalite RON 90, Several parameters have rejected the regulations. Therefore sorghum bioethanol is used as an additive for Gasoline. Sorghum bioethanol is made addictive to gasoline RON 90, namely B10 (bioethanol sorghum 10%) and B20 (bioethanol sorghum 20%). It would cause an increase in the performance of gasoline engines.

Field activities conducted to determine the level of mercury content in the water flow of Lake Payawan,Tumbang Panggo Village, Tasik Payawan District, Katingan Regency, Central Kalimantan Provincebased on laboratory test results to obtain the results of mercury content in upstream to downstream ofLake Payawan. From this research, it is necessary to test the quality of water in the laboratory in orderto analyze the water quality parameters so it can be known mercury content (Hg) in Lake Payawanwater flow. From the test results on 6 points river water samples in the laboratory of the IndustrialResearch and Standardization Center of Banjarbaru City showed the highest mercury content found insample number 3 with P. 2076 test code taken at the location of the middle Lake Payawan TasikPayawan District with mercury levels located At a rate of 0.069 μg / l or 0.000069 mg / l, this reflectsthe presence of other factors that may also affect the level of mercury content in Lake Payawan flow.

Shrinkage performance was examined of Virginia Department of Transportation-approved latex-modified and microsilica concrete overlay mixtures. Research was conducted on both field-sampled and laboratory-fabricated restrained and unrestrained specimens. From crack and delamination surveys of sampled bridge decks and laboratory test results, a shrinkage performance-based specification for the Virginia Department of Transportation was developed. There was no significant difference between the unrestrained shrinkage values of latex-modified and microsilica concrete overlay mixtures for the specified time periods. Restrained microsilica concrete specimens generally cracked earlier and more frequently than restrained latex-modified concrete specimens. However, the bridge deck crack and delamination surveys show that conditions and quality of construction and type and frequency of traffic may have a greater effect on cracking than the overlay material.

Background: Malawi has a high burden of infectious disease. The expansion of programmes targeting these diseases requires a strong laboratory infrastructure to support both diagnosis and treatment.Objectives: To assess the use of laboratory test results in patient management and to determine the requirements for improving laboratory services.Methods: A cross-sectional study was conducted in 2012 to survey practising clinicians.Two hospitals were purposively selected for observations of clinicians ordering laboratory tests. Twelve management-level key informants were interviewed. Descriptive statistics were conducted.Results: A total of 242 clinicians were identified and 216 (89%) were interviewed. Of these, 189 (87%) reported doubting laboratory test results at some point. Clinicians most often doubted the quality of haematology (67%), followed by malaria (53%) and CD4 (22%) test results. A total of 151 (70%) clinicians reported using laboratory tests results in patient management. Use of laboratory test results at all times in patient management varied by the type of health facility (P < 0.001). Ninety-one percent of clinicians reported that laboratories required infrastructure improvement. During 97 observations of clinicians’ use of laboratory test results, 80 tests were ordered, and 73 (91%) of these were used in patient management. Key informants reported that the quality of laboratory services was good and useful, but that services were often unavailable.Conclusion: Gaps in the public laboratory system were evident. Key recommendations to enhance the use of laboratory test results in patient management were to strengthen the supply chain, reduce turn-around times, improve the test menu and improve the laboratory infrastructure.
