Stockpiles are accumulations of materials such as coal or ore stored at specific locations. Accurate stockpile volume measurement is crucial in the mining and logistics industries for inventory management and cost efficiency. Conventional methods like Real-Time Kinematic (RTK) GPS rely on surface coordinate measurements but require numerous points, especially for irregular-shaped objects. Newer technologies like Terrestrial Laser Scanners (TLS) offer high-precision alternatives by capturing thousands of points per second, expediting and enhancing the resolution of volume measurements. This study compares TLS and RTK GPS methods in measuring the volume of andesite rock stockpiles at PT Bara Tabang. This research uses a quantitative approach, involving six Ground Control Points (GCPs) measured using the Sokkia GRX2 RTK GPS on October 24, 2024. TLS generated over 8.6 million point cloud data filtered down to 35,197 points, while RTK GPS yielded 2,276 coordinates. Accuracy testing showed very small RMSE values (RMSEr: 0.008 m; RMSEz: 0.007 m), and both LE90 and CE90 demonstrated 90% confidence within a 0.012 m range. Volume calculation using Surpac software with the cut and fill method showed TLS produced a volume of 18,766 bcm (51,982 tons/m³), while RTK GPS resulted in 18,694 bcm (51,782 tons/m³), with a difference of 72 bcm or 0.211%.These results indicate that both methods offer acceptable accuracy; however, TLS provides greater data density, efficiency, and precision, particularly for complex or large-scale stockpile objects. Therefore, TLS is recommended for high-accuracy volume measurement in mining operations that require efficiency and detailed analysis.

This research aims to analyze the evolution and innovation of sharia savings products in Indonesia through a literature-based qualitative approach. The background of the research is based on the significant growth of the national sharia banking sector, driven by government regulations, technological advancements, and changes in customer preferences. This study uses a literature review method by analyzing various secondary sources such as scientific journals, regulations, and financial reports to identify the patterns of Islamic savings product development over time. The research results show that the transformation of sharia savings products is driven not only by religious aspects but also by the demand for service efficiency and financial inclusion. The merger of several Islamic banks into Bank Syariah Indonesia also accelerated the digitalization of Islamic savings services. Although there are challenges such as low Islamic financial literacy and limited infrastructure, development opportunities remain wide open through educational strategies and the integration of the halal ecosystem. Innovations such as the opening of online accounts and the diversification of goal-based products have successfully increased sharia financial inclusion, particularly among the younger generation. The implications of this research emphasize the importance of adaptive product development strategies, financial education, and cross-sector collaboration to strengthen the competitiveness and sustainability of sharia savings products in Indonesia.

Mitra Abadi Mahakam as a contractor operating at PT. Bukit Baiduri Energi's jobsite, especially in the Pit A9 area, faces operational challenges related to variations in haul road grades. Differences in road gradients on the overburden hauling route have the potential to cause significant differences in fuel consumption between dump truck units, which ultimately affects the overall efficiency of hauling activities. The study was conducted quantitatively with primary and secondary data requirements and through 3 stages. The study resulted in an average fuel consumption value in loaded conditions of 1.41 liters and in unloaded conditions of 0.18 liters. The average fuel ratio value in loaded conditions was 0.62 liters/second and in unloaded conditions of 0.32 liters/second. The cost of fuel consumption in loaded conditions was Rp. 4,972,800 ($301.92) and in unloaded conditions of Rp. 2,607,360 ($158.30)

This study aims to evaluate the extent to which service quality, store atmosphere, and the implementation of proactive strategies contribute to business strategy at CV MM Acing Jaya located in Pangkalpinang. This study uses a quantitative approach with data collection techniques through distributing questionnaires to 71 respondents consisting of customers and business partners of the company. Multiple linear regression analysis was used to test the research hypothesis consisting of three independent variables (service quality, store atmosphere, and proactive strategy) and one dependent variable (business strategy). The results showed that store atmosphere and proactive strategy had a positive and significant effect on business strategy, while service quality showed no significant effect. The findings suggest that the creation of a supportive store atmosphere and the implementation of responsive and innovative strategies are important factors in strengthening the competitiveness of ritel companies. This research provides a practical contribution for businesses in developing business strategies that are more adaptive and oriented to consumer needs.

Passengers or users of air transportation services are increasingly experiencing flight delays and cancellations. Where the Super Air Jet airline experienced damage resulting in flight cancellations, which resulted in passengers experiencing losses in terms of both material and time. This study aims to determine how air transportation is responsible for flight delays and cancellations at the airport. This study uses a qualitative method, where this study is descriptive. Data collection in this study was through interviews, observations and documentations in the field. The results of this study indicate that air transportation is required to provide passengers with rights, namely compensation in accordance with applicable provisions in the form of food and drinks and Rp. 300.000,00 (three hundred thounsand rupiah). However,in practice passenger rights are not in accordance with receiving compensation provided by the airline. This study concludes that there must be supervision, law enforcement and firmness so that passenger rights can be protected and receive optimal justice in the world of aviation.

This research is motivated by the low enthusiasm, participation, and creativity of students in social studies learning which is considered boring and difficult, resulting in low learning outcomes. One effort to overcome this problem is to apply the Project Based Learning (PjBL) learning model based on the Mirigambar Temple photography project through Blogger media. This study aims to determine the effect of PjBL on learning outcomes, creativity, and both simultaneously. The study used a quantitative approach with a quasi experimental nonequivalent control group design. The sample consisted of 20 control class students and 20 experimental class students selected using the purposive sampling technique. The instruments used were creativity questionnaires and learning outcome tests. Data analysis used the Independent Sample T-Test and MANOVA. The results showed that PjBL learning had a significant effect on learning outcomes, creativity, and learning outcomes and creativity of students together. These findings indicate that the application of PjBL through a Blogger-based photography project can create active, enjoyable learning, and is able to optimally increase student potential, so it is worthy of being an alternative strategy for learning social studies in schools.

The purpose of this study was to see how promotions and live streaming features impact the decision of Shopee users to purchase fashion products in the 2022 intake. This quantitative study involved 54 respondents from a population of 117 students selected through a simple random sampling method. Primary data were collected through online questionnaires and analyzed using multiple regression using SPSS. Validity, reliability, classical assumptions, and hypothesis tests were also conducted. The study shows that students of Economics Education, Sebelas Maret University, 2022 intake significantly choose fashion products because of promotions and Shopee's live streaming features. Promos are considered to be able to save consumer spending, thus increasing interest and enthusiasm for transacting through the Shopee application. Meanwhile, the live streaming feature makes it easier for consumers to see products directly, assess quality, and make purchases more practically. As for further researchers, it is recommended to add other variables (for example, consumer trust), compare with other e-commerce platforms, use mixed methods, analyze different user segments, and examine the long-term impact on brand loyalty.
