Design and Implementation of a Composite Array Resistivity Data Logger for High-Resolution 2D Inversion Modeling
Get PDFThe use of resistivity meters to model subsurface conditions is widespread. However, commercial instruments are mostly limited to conventional configurations, such as Wenner, Schlumberger, and dipole-dipole. Moreover, we cannot modify the program on the instrument. In this study, we designed and implemented a DC resistivity meter that can potentially be developed in the future and can be used in composite array configurations. This instrument uses a half-bridge SMPS as a power supply, which is capable of generating a large power, an Arduino Uno, and several sensor modules as part of a flexible and easy-to-program control unit. We conducted laboratory and field tests, comparing two types of configurations, namely Wenner and composite arrays (dipole-dipole and gradient). We then processed the data using ResIPy software, which enables displaying complex data sets in the form of 2D cross-sections and assessing the quality of post-processing data. We obtained good data with low RMS misfit that matched the synthetic media created in laboratory testing and compared well with previous research
Content validity of D-MESS: Articulate storyline 3-based learning media in sport massage courses
Get PDFThe development of innovative learning media is one of the solutions for educators in the learning process in higher education in the current era of digital and technological disruption. Interactive learning media are relevant to be applied in hybrid or blended learning methods. The purpose of this study was to find out the results of validating D-MESS content as an interactive learning medium in sports massage courses. The data used in this study are quantitative data obtained from questionnaires filled out by learning experts, media experts, and programming experts. The data analysis technique used is quantitative descriptive, which is oriented towards the Content Validity Index (CVI) approach. The results of the validation test on D-MESS show that, from the educational aspect, a value of 0.89 is obtained, on the aspect of program display, a value of 0.91, and on the aspect of technical quality, a value of 0.83. Referring to these results, the interactive learning media for the sports massage course, which is named D-MESS, has a high level of validation, both from the educational aspect, program appearance, and technical quality. So that the relevance of all components of the three aspects, such as curriculum suitability, content of learning materials, interaction, feedback, coloring, graphics, sound, animation, display between screens, ease of use, and program security, is very good, even though there are minor revisions. Furthermore, with this very high D-MESS validation value, it is suggested for future research

Efektifitas Kearsipan Dalam Meningkatkan Pelayanan Administrasi di Desa Bulu-Bulu Kecamatan Tonra Kabupaten Bone
Get PDFThis study aims to determine the effectiveness of records related to administrative services in Bulu-Bulu Village. This research uses a quantitative approach. The results of the study revealed that in general 42.85% of respondents rated archive management as very good, 42.85% good and 14.28% bad. Archive management so far is going well. In fact, the human resources in the archiving department at the Bulu-Bulu village office are very limited, because the archivists do not have basic knowledge about the archiving department. The low quality of management services is caused by several factors such as: B. unclear procedures, confusing technical and administrative requirements, the completion time that exceeds the specified time, the lack of transparency of the costs incurred and the distance of the place of residence from the place of residence. village office. It can be concluded that (1) the effectiveness of archives in improving administrative services in Bulu-Bulu Village, Tonra District, Bone Regency, namely the procedure for making archives is good, but there is no method used that facilitates management by making it faster and more efficient. (2) The factors that encourage and hinder the improvement of administrative services are the public's appreciation of public service users, the clarity of technical and administrative requirements, and the knowledge of staff about the administrative service industry
DEVELOPMENT OF MATHEMATICAL LEARNING DEVICES ON TRIGONOMETRY MATERIAL WITH THE PEER TUTORING METHOD
No full textThis study aims to produce mathematics learning tools in the form of syllabi, learning implementation plans (RPP), and student worksheets (LKPD) using the peer tutoring method in senior high schools that are tested for validity. The development of learning tools in this study uses the ADDIE development model which consists of 5 stages, namely Analysis, Design, Development, and Evaluation. However, due to Covid-19 constraints, researchers can only develop the ADDIE model up to the Analysis, Design, and Development stages. The data collection instrument in this study used syllabus validation sheets, lesson plans validation sheets, and worksheet validation sheets. The data collection technique used was validation data from 2 Lecturers of FKIP Mathematics at Riau Islamic University and 2 Mathematics Subject Teachers at SMA PGRI Pekanbaru. The data analysis technique used is a descriptive statistical analysis which describes the data that has been collected and will be tested for its validity. From the results of the validity test, it was obtained that the syllabus validation results were 93.02% with very valid information, the RPP validation results were 96.36% with very valid information, and the LKPD validation results were 95.80% with very valid
 
Video tutorial-based learning media: A solution to assist students in learning sepaksila sepaktakraw skills
Get PDFThe use of video learning media has been believed to play an important role in facilitating the teaching and learning process. However, limited video learning media are available for teaching the sepak takraw course. To fill this need, this research aimed at developing a video tutorial to assist students in learning the sepak sila skill at the sepak takraw course. The study applied research and development (R & D) design with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model. Data were collected through a questionnaire and an interview. A questionnaire was used to collect the students’ needs, the validity of the product, and the students’ perceptions about the product. An interview was conducted to seek feedback from the experts (a content expert, a design expert, a learning media expert, and a practitioner or coach) related to the developed product. The data were analyzed quantitatively and qualitatively. The results show that the developed product was feasible to use. This was proven by the average score of the product validity, which was 4,7 (very good). The results of the field trials also showed very good results (4, 8). The students perceived the developed product positively, in that it could arouse their motivation to learn, was easy to understand and follow, and could help them enhance their sepak takraw skills. The study's findings could enrich existing theories about the importance of using learning media in teaching as well as provide a practical contribution in that the developed product can be used by both sepak takraw lecturers and students to improve students' sepak takraw skills
Economic Evaluation Of Water Production Management With Rpm (Relative Permability Modifier) Treatment Based On Gross Split Contract In “Re” Well In “Dn" Field
Get PDFThe "RE" well in the "DN" field is an oil well produced in June 2004 with an initial water cut value of 15% as time went on there was a fairly high increase in the water cut value reaching 97% which means that it caused increased water production. and oil production decreased from 387 BOPD to 11 BOPD.
Appropriate handling in overcoming excessive water production, one of which is by using a method that can selectively restrain water production without restraining hydrocarbon production with RPM (Relative Permeability Modifier) Treatment. RPM (Relative Permeability Modifier) is a type of polymer with a high molecular weight as the main molecule of RPM. RPM can be done without isolating the layer zone so that it can be injected bullhead into all layer zones to reduce water permeability.
This final project research has been seen from increasing the rate of oil production and decreasing the water cut. The selected well is the "RE" well in the "DN" field which has an increasing water cut value and decreased oil production. Then calculate the economy using the gross split method to calculate the feasibility level of the RPM (Relative Permeability Modifier) Treatment project.
