Extraction transformation load (ETL) solution for data integration: a case study of rubber import and export information

Data integration is important in consolidating all the data in the organization or outside the organization to provide a unified view of the organization's information. Extraction Transformation Load (ETL) solution is the back-end process of data integration which involves collecting data from various data sources, preparing and transforming the data according to business requirements and loading them into a Data Warehouse (DW). This paper explains the integration of the rubber import and export data between Malaysian Rubber Board (MRB) and Royal Malaysian Customs Department (Customs) using the ETL solution. Microsoft SQL Server Integration Services (SSIS) and Microsoft SQL Server Agent Jobs have been used as the ETL tool and ETL scheduling

Karakteristik Hidrokimia Akibat Pengaruh Formasi Batuan pada Mata Air Panas di Desa Wukirharjo, Kecamatan Parengan, Kabupaten Tuban, Jawa Timur

Penelitian dilakukan di desa Wukirharjo, Kecamatan Parengan, Kabupaten Tuban, Jawa Timur tentang pengaruh formasi batuan terhadap karakteristik hidrokimia sumber mata air panas dengan suhu mencapai 500°C di Wana Wisata Prataan. Penelitian ini bertujuan untuk menentukan parameter fisika dan kimia yang terdapat pada sumber mata air panas dan selanjutnya dianalisis hubungan kandungan logam yang dimiliki sumber mata air panas terhadap formasi batuan di daerah Kecamatan Parengan. Pengujian bau dan rasa langsung dilakukan di lokasi penelitian dengan sedikit berbau sulfur dan tidak berasa, sedangkan nilai pH adalah 6,5yang termasuk pada kategori asam. Kandungan sulfur pada mataair panas ini cukup tinggi yaitu 153 mg/L dan nilai kesadahan 65,8mg/L tetapi masih dibawah baku mutu air bersih yang ditetapkan. Sumber mata air panas yang tersingkap di daerah Wukirharjo tersusun atas batugamping dan batupasir kuarsa yang termasuk dalam zona rembang. Dimana zona ini merupakan formasi ngrayong yang terbentuk karena adanya silika yang didominasi oleh logam Fe dengan konsentrasi 10,554 mg/L dan Al dengan konsentrasi 4,552 mg/L. Sumber mata air panas ini memiliki TDS rendah dengan nilai 8,3mg/L dan digolongkan sebagai air lunak (soft water), sehingga masih layak sebagai air pemandian

Design of planar dielectric resonator antenna array at 28 GHz

This article presents a planar array of rectangular Dielectric Resonator Antenna operating for 28 GHz applications. The proposed antenna is formed through two stages of designs which are a single element and planar array. It is made up from a ceramic material with a dielectric constant of 10 and mounted on RT/Duroid 5880 with a relative permittivity of 2.2 and a thickness of 0.254 mm. A prospective study using three different configurations of three by three planar array is done in order to obtain the best performance in terms of bandwidth, gain, and cost reduction. Besides that, this study is also conducted for a beam steering capability of each configuration. Finally, the best configuration is proposed for 5G application

Diversity of Cellulolytic Microbes and the Biodegradation of Municipal Solid Waste by a Potential Strain

Municipal solid waste contains high amounts of cellulose, which is an ideal organic waste for the growth of most of microorganism as well as composting by potential microbes. In the present study, Congo red test was performed for screening of microorganism, and, after selecting a potential strains, it was further used for biodegradation of organic municipal solid waste. Forty nine out of the 250 different microbes tested (165 belong to fungi and 85 to bacteria) produced cellulase enzyme and among these Trichoderma viride was found to be a potential strain in the secondary screening. During the biodegradation of organic waste, after 60 days, the average weight losses were 20.10% in the plates and 33.35% in the piles. There was an increase in pH until 20 days. pH however, stabilized after 30 days in the piles. Temperature also stabilized as the composting process progressed in the piles. The high temperature continued until 30 days of decomposition, after which the temperature dropped to 40°C and below during the maturation. Good quality compost was obtained in 60 days

Optimization for the Production of Cellulase Enzyme from Municipal Solid Waste Residue by Two Novel Cellulolytic Fungi

The main purpose of this study is to reduce the production cost of cellulase by optimizing the production medium and using an alternative carbon source such as municipal solid waste residue. In the present investigation, we aim to isolate the two novel cellulase producing fungi (Aspergillus niger and Trichoderma sp.) from municipal solid waste. Municipal solid waste residue (4-5% (w/v)) and peptone and yeast extract (1.0% (w/v)) were found to be the best combination of carbon and nitrogen sources for the production of cellulase by A. niger and Trichoderma sp. Optimum temperature and pH of the medium for the cellulase production by A. niger were 40°C and 6-7, whereas those for the production of cellulase by Trichoderma sp. were 45°C and 6.5. Cellulase production from A. niger and Trichoderma sp. can be an advantage as the enzyme production rate is normally higher as compared to other fungi

Permission from IEEE must be obtained for all other users, including reprinting/ republishing this material for advertising or promotional purposes, creating new collective works for resale or redistribution to servers or lists, or reuse of any copyrighted components of this work in other works.This paper presents the findings of a steerable higher-order mode (TEy 1δ3) dielectric resonator antenna with parasitic elements. The beam steering was successfully achieved by switching the termination capacitor on the parasitic element. In this light, all of the dielectric resonator antennas (DRAs) have the same dielectric permittivity similar to that of 10 and was excited by a 50Ω microstrip with a narrow aperture. The effect of the mutual coupling on the radiation pattern and the reflection coefficient, as well as the array factor were investigated clearly using MATLAB ver. 2014b and ANSYS HFSS ver. 16. As the result, the antenna beam of the proposed DRA array managed to steer from -32° to +32° at 15 GHz. Furthermore, the measured antenna array showed the maximum gain of 9.25 dBi and the reflection coefficients which are less than -10 dB with the bandwidth more than 1.3 GHz, which is viewed as desirable for Device-to-Device communication (D2D) in 5G Internet of Things (IoT) applications

Association of TNF-α G308A gene polymorphism in essential hypertensive patients without type 2 diabetes mellitus

This study aims to investigate the effects of tumor necrosis factor alpha (TNF-α) G308A gene polymorphism on essential hypertension (EHT) with or without type 2 diabetes mellitus (T2DM). The project was conducted on buccal epithelial and blood cells for case and control patients, respectively. Epithelial cells were obtained from the inner part of the cheeks. Techniques including DNA extraction, polymerase chain reaction (PCR), and restriction fragment length polymorphism (RFLP) were utilized to assess biomarkers of DNA damage. Our results demonstrated significant differences between wild and mutated genotypes among EHT patients without T2DM. We also found a significant association between wild and mutated allele frequencies in EHT patients (P < 0.05). Clinical characteristics between the groups (EHT with or without T2DM and controls) showed statistically significant association (P < 0.05). Overall, we show that G308A polymorphism of the TNF-αgene may be a significant genetic risk factor for EHT without T2DM patients in Malaysia
