<![CDATA[Dalam metode magnetik, medan magnet anomali disebabkan oleh sumber medan magnet dipol. Setiap tempat memiliki sudut iklinasi dan deklinasi magnetik yang berbeda sehingga menyebabkan peta anomali magnetik bersifat kompleks dan interpretasinya menjadi relatif sulit. Untuk mengatasi kerumitan dalam interpretasi data magnetik, penggunaan transformasi reduksi ke kutub RTP sangat penting dilakukan. Tapis RTP dengan memanfaatkan fungsi-fungsi built in Matlab telah berhasil direalisasikan dan diaplikasikan pada data magnetik WDMAM wilayah Tapal Kuda-Jawa Timur. Nilai sudut inklinasi I = -32.82° dan sudut deklinasi D = 0.72° digunakan pada aplikasi RTP daerah ini. Anomali magnetik hasil RTP menunjukkan bahwa terjadi perubahan rentang nilai medan magnet yaitu dari -345.51 nT s.d 282.30 nT menjadi -975.37 nT s.d 782.38 nT. Selain itu, terjadi pergeseran lokasi klosur anomali magnetik positif dan negatif. Anomali magnetik positif mendominasi di bagian tengah sampai utara Wilayah Tapal Kuda dan diduga berkaitan dengan Zona Vulkanik Kuarter. Klosur-klosur anomali positif mengalami pergeseran letak ke barat di sekitar Gunung Bromo dan Gunung Argopuro. Anomali magnetik negatif mendominasi tepi selatan Wilayah Tapal Kuda dan diduga berkaitan dengan Zona Pegunungan Selatan. Klosur anomali negatif juga mengalami pergeseran letak yaitu ke barat daya mendekati gunung Semeru.]]>

<![CDATA[This study aims to analyze and provide empirical evidence about the influence of the five variables of service quality in PT. XYZ namely reliability (X1), empathy (X2), responsiveness (X3), tangible (X4), and assurance (X5) have an effect on customer satisfaction in PT. XYZ. Data were collected by using questionnaires, data analysis technique used in this research is multiple linear regression analysis. The results of multiple linear regression analysis that has been done shows that all independent variables consisting of reliability, empathy, responsiveness, tangible, and assurance has a coefficient with a positive coefficient direction. This proves that all independent variables have a positive influence on the dependent variable of customer satisfaction. From the determinant coefficient (R2) obtained amounted to 0.969 this means 96.9% customer satisfaction is influenced by variable reliability, empathy, responsiveness, tangible, and assurance. The rest is affected by other factors that are not explained in the regression obtained in this study. Variable assurance is an independent variable that most influence on the dependent variable is 0.387.]]>

<![CDATA[Production activities at manufacture companies are often inconvenient. One of them is due to the incompatibility of workersanthropometry with the work facilities used. Disergonomics like this will cause complaints in the skeletal system. Complaints to this damage are termed musculoskeletal disorder (MSDS). The production process of making shoes at UD. Kurnia at the subordinate work station identified that work posture has the potential to cause injury to the arm, back and leg muscles with a percentage of 66.67%, 68.89% and 30%. So it is necessary to improve work posture. In this study, the OWAS method was used to identify and evaluate hazardous work postures. Meanwhile, to improve work posture, work facilities are designed using anthropometric data for subordinate work station workers. Owas identification results show that the work posture is more ergonomic. Then the results of the WinOwas software show that the improvement of work posture with the design of work facilities is included in category 1. Which means that the work posture is not dangerous. So it is directly believed that workers complaints on skeletal muscles or MSDs at subordinate work stations can be minimized.]]>

<![CDATA[Today, almost all activities in various sectors of life have been transformed into digital systems to support various related activities. Consideration of the efficiency of dissemination of information outreach and data management that can be recorded properly is the main reason for switching to a digital system. In the economic sector, global business developments are rife with the use of digital devices in marketing various products to increase marketability. Based on this, this research was conducted to apply the Apriori algorithm association data mining to provide product recommendations for online shop customers. The CodeIgniter framework and the waterfall method are used to build a website-based information system. Sampling data was obtained from transaction data at the Rizvenastore store which was used for the database using MySql. The application of the a priori algorithm can form association rules as a reference in-store product promotions and decision support in providing product recommendations to customers based on predetermined minimum support and confidence values. From testing the system using the black box method, the results obtained for all activities on all actors can run as expected.]]>

<![CDATA[The Multibeam Echosounder is a tool for determining the depth of water by sweeping large areas of the seabed. The operating principle of this tool in general is based on the emission of pulses that are emitted directly towards the seabed and after that acoustic energy is reflected back from the seabed (seabel), several sound beams (beams) are electronically generated using signal processing techniques so that the beam angle is known. . Multibeam echosounder can produce high-resolution bathymetry data. The Multibeam Echosounder is characterized by the following parameters Frequency in the range 12 to 500 kHz. Sweep angle range is between +75 ͦto 85 ͦ, Accuracy generally decreases as swath width increases. The width of the sweep is 4x to 5x the water depth and the addition of the swath width depends on the depth of the survey. Using Multibeam Echosounder (MBES) acoustic equipment can improve data quality and the survey area coverage is able to obtain data coverage with a wider area, more detailed data as well as time efficiency and cost effectiveness..]]>
