This study seeks to identify best practices, uncover implementation gaps, and provide recommendations to improve the quality and comparability of financial reporting in the sector. This study employs a qualitative case study approach to gain an in-depth understanding of the implementation of PSAK 64 in Indonesian oil and gas companies operating under the Production Sharing Contract (PSC) model. The sample is selected using purposive sampling, focusing on companies that: Operate in the upstream oil and gas sector in Indonesia, are governed by the PSC model, and have published financial reports in accordance with PSAK 64. The study findings reveal that while companies generally comply with the basic requirements of PSAK 64, there is considerable variation in the interpretation and application of specific provisions, particularly those related to the recognition, measurement, and disclosure of exploration and evaluation (E&E) assets. This study contributes to the accounting literature by highlighting how a single standard (PSAK 64) can be applied differently based on the contractual and regulatory environment.

This study compares the performance of a bearing with surface waviness liner to a plain bearing. Both bearings are functioned with palm oil as lubricant so that the potential advantages of the journal bearings could be identified. CFD analysis is developed to predict the numerical data for full film lubrication condition. A bearing of 60 mm in diameter with its ratio of length to diameter is 0.5, a clearance 250µm, and 200µm of wave amplitude is simulated. Semi circular wavy surface produces better results in term of load capacity than the plain journal bearing for a small eccentricity. The load carrying capacity is influenced by the increasing in speed of the shaft and the eccentricity ratio.

At present the determination of weight and volume has been widely used to assist in the process of determining costs for freight forwarding services. Shipping costs are determined by the weight of the goods, but the weight of the goods consists of two types, namely actual weight and volume weight. The weight of the weighing will be used directly if the item or box is small, but if the item is large but the weight is real then the weight of the volume will be used. Algorithms that combine triangulation and 2D measurement techniques can be used to build 3D surfaces so they can measure the volume of a product. Determination of volume in the optical scoring system can be done using the laser triangulation method and the area of 2D image measurement, then using a computer algorithm to get the results of 3D images to determine the volume of the object. The calculation process used in this study uses MATLAB software. MATLAB is the most efficient software for matrix-based numerical calculations and is widely used in mathematical calculations, development and algorithms, programming modeling, prototyping and simulation, data analysis, exploration and visualization, numerical and statistical analysis, and technical application development. The results of the study using MATLAB include students becoming more interested in learning and more independent in learning mathematics, can visualize data graphically to help analyze the data analyzed, and help in modeling the characteristics of variations in fuel mixtures which include density, viscosity, dynamic and kinematic viscosity.
