Abstract

The purpose of this study is to analyze the potential of share waqf in West Sumatra. In analyzing the potential of share waqf, researchers will relate it to the potential possessed by the people of West Sumatera both in terms of material potential and non-material potential, such as religiosity and humanist. This study uses a survey method by distributing questionnaires to 135 samples. The target sample of this research is the Muslim community of West Sumatra. Respondent data obtained will be processed using the IBM SPSS Statistic 20 application to test the validity and reliability of the data. The results of this study indicate that share waqf has enormous potential in West Sumatra. From the material side of potential, many Muslim communities in West Sumatra are familiar with investing, save regularly, and agree that investment is very important. Likewise, from the potential non-material side of religiosity, the Muslim community of West Sumatra agrees that share waqf is in accordance with Islamic law and as an innovation in muamalah. Other potential of share waqf in West Sumatra can also be seen from the potential of the humanist non-material side that shows public concern for other human beings.

Abstract

This study aims to analyze the use of the Enterprise Resource Planning application Oracle E-Business Suite (ERP-EBS) as a support system for the sales cycle at PT Penta Valent Padang Branch. The research employs a descriptive qualitative method, with data collected through interviews and document reviews. The findings indicate that ERP-EBS has been comprehensively implemented across almost all business activities at the branch, covering customer order processing, inventory management, product delivery, as well as receivables, payment collection, and operational expense recording. Each department has clearly defined and integrated responsibilities, allowing business processes to run efficiently and be well-documented. In terms of benefits, the system enhances administrative efficiency, improves data accuracy, enables real-time transaction tracking, and strengthens internal control through interdepartmental data integration. However, the study also identifies challenges, such as the need for user adaptation due to system complexity and potential technical disruptions from the central server. Overall, the implementation of ERP-EBS has proven effective in improving the efficiency and effectiveness of the sales cycle at PT Penta Valent Padang Branch and supports positive user acceptance in line with the Technology Acceptance Model.

Abstract

Telkomsel has introduced 5G technology in Padang City, evaluated through drive tests using G-Nettrack Pro software to measure Reference Signal Received Power (RSRP) and Signal to Interference plus Noise Ratio (SINR). The tests revealed RSRP values ranging from -44 dBm to -100 dBm and SINR values between -12 dB and 26 dB. While high RSRP does not always guarantee high throughput, higher SINR consistently improves throughput, with the highest throughput reaching 153,053 kbps at SINR levels between 10 and 30 dB. Modulation and Carrier Aggregation (CA) also play a significant role, with 64-QAM modulation combined with CA achieving throughput up to 31,500 kbps, compared to 6,300 kbps without CA. Although CA bandwidth decreased from 100 MHz to 50 MHz, throughput remains higher compared to 20 MHz bandwidth without CA. CA proves highly effective in enhancing throughput through larger bandwidth and more efficient modulation. Additional factors such as handover, interference, and physical and weather conditions also impact network performance. Overall, Telkomsel’s 5G network in Padang City meets the company’s Key Performance Indicators (KPI), despite some areas with suboptimal signal quality.
