Rice husk biochar is commonly used as ameliorants, moreoverit has ability to absorb and degradeharmful chemicals. This study aimed at investigating the effectiveness of rice husk biochar application towards the persistence of metsulfuronmethyl in soil and seepage water. This study applied completely randomized design factorial with two levels of herbicide dose (0 and 300 gr/ha) and four levels of percentage of rice husk biochar(0%, 5%, 10% and 15% of total soil). The results of this research revealed that there was no metsulfuron methyl residue in soil of all treatments after 28 days of herbicide treatment. The residue was found in seepageas much as 7.7 μg/L in treatment of 0% husk biochar and 6.8 μg/L in treatment of 5%husk biochar. The seepage reduced by the increasing of the percentage of rice husk biochar application. Thus, it can be concluded that giving the rice husk biochar is effective for absorbing metsulfuron methyl and preventing it from leaching. However, itcould not hold the presence of metsulfuron methyl longer in soil.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131330641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The value of compressive strength permitted in drilling is 500 psi while for shear bond strength is 100 psi. To increase the strength of cement is done by adding pozzolanic additives. One alternative pozzolan that can be used and derived from inorganic waste is coal fly ash. Indonesia has reserves of around 38.9 billion tons of coal with annual production reaching 435 million tons, resulting in a large amount of coal fly ash. The silica contained in coal fly ash is pozzolan which can increase the strength of cement and can reduce costs because it does not need to use additives from industry and can also reduce environmental pollution from fly ash. This study was conducted to determine the value of compressive strength and shear bond strength by using coal fly ash additives with variations in concentrations of 2.5%, 5%, 7.5%, 10%, 12.5% and 15% by weight of cement (BWOC). Making cement suspension samples is done by mixing water, bentonite, polypropylene glycol, CaCl2, and coal fly ash softens the mixer, then it is poured in a mold and left in the water bath. The residence is carried out for 24 hours with temperature 60 0 C. Compressive strength and shear bond strength test can be done by utilizing hydraulic pressure. The addition of coal ash can increase the strength of cement. The optimal compressive strength and shear bond strength is obtained on 7.5% BWOC additively ash coal with the value of compressive strength obtained is 1680.39 psi and the shear bond strength is 138.88 psi.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126299069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forest fires in the dry season occur in most of Indonesia’s forestry areas. Riau Province is located on the island of Sumatra, Indonesia, in an area with a high likelihood of forest fires due to typical peatlands. The purpose of this research is to design and contribute to new technologies for fire detection using Wireless Sensor Networks (WSNs) Technology and intelligent software for accurate fire detection. This study proposes WSNs for the detection of forest fires in peat areas using sensor nodes with several embedded sensors for accurate fire detection. The sensor node prototype was designed and tested in a laboratory to check results and calibrate it to the real environment. Four sensors are embedded with temperature and humidity sensors, fire and smoke detection sensors and particle sensors. It analyses with intelligent software to get accurate information and data from the fire, including location, detection of values from all sensors. The results show that WSNs sensor nodes can detect fires and send information about all parameters that indicate forest fires. The design and development of WSN sensor nodes is to assist local governments or institutions to overcome existing problems, particularly in Riau Province and Indonesia, due to forest fires.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130380158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides being a problem, it also becomes extra energy to produce oil and gas. OWC is one of the keys for water production determination for each layer. If the perforation at production well is at OWC or below OWC, the production will be 100% water. In general, the log is used to determine OWC. Besides with log, tank modeling from the material balance equation is also used to determine OWC. WH field located 15 km from Bangko Field in Riau. This primary field has high water production with 97% water cut. Before tank modeling starts, each layer needs to be analyzed based on its reserves, production cumulative and remaining reserves to determine the productive layer, which can be developed in the future. Prediction can be done when history matching and calibration process for both historical data and simulated data by software. Prediction ends in August 2021, which is the end of development contract in WH field. From the results, it can be determined that from C sand, the OOWC and COWC are at 2922 ft and 2883 ft with the cumulative oil production is 6.78 MMSTB. From E sand also can be determined the OOWC at 2368 ft and COWC at 2325 ft with the cumulative oil production is 14.57 MMSTB. From K sand, the OOWC is at 2002 ft and COWC at 1911 ft with the cumulative oil production is 13.5 MMSTB. L sand the OOWC is at 2243 ft and COWC at 2191 ft with the cumulative oil production is 29.17 MMSTB. From the analysis, K sand has the most significant OWC movement, which is 91 ft and it is also validated with the current log data. This sand needs more care to maintain water production.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133292019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Green mussels ( Perna viridis ) are one of the organisms known to accumulate heavy metals. Biosurvey needs to be conducted to acquire information on heavy metal content in man-made habitat and biota. The aims of this research are to identify the water quality related to heavy metal presence; to measure heavy metal content in green mussels ( Perna viridis ) around the reclaimed island to determine heavy metal level pollution on reclamation island. Sampling was conducted in August 2017 in reclamation islands C and D. Heavy metal measurement values refer to the SNI method 3554-2015. Data of heavy metal content in water, sediment, and green mussels were analyzed with quantitative descriptive method. The results show biological oxygen demands (BOD), and chemical oxygen demands (COD) has exceeded the water quality standard which indicates a high level of pollution. The results of the examination of the heavy metal in seawater show that mercury (Hg), cadmium (Cd), and lead (Pb) are below the tools detection limit ( < 0.0002; < 0.00011; < 0.00086 mg/L) and below seawater pollution standard for biota. Concentrations of heavy metals mercury, cadmium, and lead in sediments around the reclaimed islands and Teluk Naga area are below heavy metal pollution standards for sediments. Mercury (Hg) levels below the tools detection limit ( < 0.0004 mg/L); cadmium (Cd) ranges from 0.02-0.20 mg/L; lead (Pb) ranges from 0.50 to 5.46 mg/L. Heavy metals examination in green mussels indicate that mercury (Hg), cadmium (Cd), and lead (Pb) are below the tools detection limit ( < 0.001; < 0.00011; < 0.00086 mg/L) and below the heavy metal pollution standard on bivalves. Generally, water and sediment around the reclaimed islands and natural habitat in August 2017 are not polluted by heavy metals so there is no harm to biota. Heavy metals quality in water, sediment and mussels are below the pollution standard and based on the USEPA system belong to grade A. The heavy metal index on Reclaimed Island is 18 and considered good. Based on the results obtained, it can be concluded that the reclaimed islands C and D in August 2017 were safe from heavy metal mercury, cadmium, and lead pollutions.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122276369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collected data that will be used in future needs should be kept well to make it easy to inquire. The data stored in a database consists of several groups of data relations. These relations should be connected through fields which are unique to the relations linked. In designing database itself, it is very important to note how data is organized and stored to minimize data redundancy. The tools used in depiction of the relationship between tables or entities are Entity Relationship Diagram (ERD) that can have one to one, one to many and many to many relationships. Gerund entity will be formed if the relationship between the entities is many to many. However, the new entity is still a possible anomaly. The reanalysis is needed to be free of anomalies. Gerund entity that still has an anomaly will form a new entity again, which in this case referred to as a sub gerund entity which is a derivative of a gerund entity. The result of a good database design or free of anomalies will increase the optimization of memory usage, consistency and integrity of data.","PeriodicalId":382428,"journal":{"name":"Proceedings of the Second International Conference on Science, Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127847849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
