Abstract

The GX Office & Co Working Bali construction project faced significant delays in the 27th week with a deviation of -4.31%, which could result in increased costs and delays in completion. So, an effective solution is needed to overcome project delays and ensure that the project is completed on time and within budget. This research aims to examine the application of the Earned Value Method (EVM) in evaluating the performance of the GX Office & Co Working Bali project by calculating the Estimated Temporary Schedule (ETS), Estimated All Schedule (EAS), Estimate Temporary Cost (ETC) and Estimate All Completion (EAC). The research uses descriptive quantitative methods by collecting data from weekly project progress reports, actual costs, and planned values. Data analysis was carried out by calculating Planned Value (PV), Earned Value (EV), Actual Cost (AC), Cost Performance Index (CPI), Schedule Performance Index (SPI), ETS, EAS, ETC, and EAC. The research results show an ETS value of 114 days with an EAS of 303 days. So, there is an additional time of 9 days from the planned schedule. ETC results amounted to IDR 3,723,631,710.12, with EAC amounting to IDR 7,699,818,710.12. So, the cost of completing the project is lower than planned, with a difference of IDR 2,545,727,760.88. The results of this research contribute to the project management literature by showing the effectiveness of EVM in identifying deviations and the basis for making strategic policies needed so that projects can be completed on time according to plan.

Abstract

In rapid construction developments, delays still occur frequently and have not been resolved, as experienced by the GX Office & Co Working Bali project. The project will be completed in 42 weeks, but in the 27th week, there is an indication of a delay of -4.31% from the initial plan. Earned Value Method (EVM) is a time and cost performance assessment method that can be used to develop strategies to minimize delays. This research aims to evaluate the time and cost performance of the GX Office & Co Working Bali project using the EVM method. A quantitative approach is used to collect and analyze project schedules, actual costs, and progress reports. EVM key indicators such as Planned Value (PV), Earned Value (EV), and Actual Cost (AC) are analyzed to determine Schedule Variance (SV), Cost Variance (CV), Schedule Performance Index (SPI), and Cost Performance Index (CPI). The results showed that the project experienced delays, especially from week 1 to week 14 and week 19 to week 27, with SPI values mostly below 1. However, the project showed increased efficiency in cost management with values CPI above one after week 14 to week 27, indicating that the actual costs incurred are lower than the value of the work completed. These findings highlight the need for corrective actions and more effective management strategies to address delays efficiently in terms of costs.

Abstract

توصل الباحث من هذه الدراسة إلى استنتاج وهو أن مفهوم التربية القيادية لطارق السويدان تربوي، وتدريبي، وواقعي، وأسوتي، وإسلامي، بمعنى أن تشكيل قائد هو من خلال التعليم والتدريب ووفق الواقع، وليكون نموذجا، وبالمعايير الإسلامية، وأن مفهوم التربية القيادية لطارق السويدان هو تعزيز نظرية وارن بلانك باسم "108 مهارات قيادية طبيعية" وهي النظرية التي أكدت على أنه لا يوجد شخص ولد قائدا في شكل طبيعي، لأن القيادة هي مجموعة من الخصائص والمهارات التي يمكن تعلُّمها، وأن تطبيق مفهوم التربية القيادية لطارق السويدان في إندونيسيا هو باسم "برنامج تعليم وتدريب الشباب القيادة الإسلامية 30 ساعة"، والتطبيقات للتربية القيادية الإسلامية وفق منظور طارق السويدان هي برنامج التعليم والتدريب القيادي الذي يُقدَّم للشباب الذين هم من أشد الموارد البشرية خصبة، خطوة خطوة، في مؤسسة أو دورة تدريبية أنشئت خاصة بهذا الغرض، وذلك باستخدام مختلف أساليب التعليم والتدريب المتنوعة، وأن مثل هذا التعليم حدث ولا يزال يحدث في واقع المجتمع الإندونيسي مما يؤكد على أهمية دور الكيايات (الشيوخ) في البسانترينات (المعاهد الإسلامية) في إعداد كوادر العلماء الذين هم قادة للمستقبل. The conclusion of this research is that the concept of leadership education of Thariq as-Suwaidan is the concept of leadership education that having the characteristic of tarbawi, tadribi, waqi‘iy, uswati and Islami. In the sense of the formation of a leader must be through education, training, reality, model, and Islamic. Thariq as-Suwaidan’s Leadership Concept is to strengthen Warren Blank’s theory by the name of “108 Skills of Natural Born Leaders”, the theory that there is no natural leader. Leadership is a collection of traits and skills that can be learned. Application of Thariq as-Suwaidan Leadership Education Concept in Indonesia is under the name of “Youth Leadership Education Training Program 30 Hours”. The application of Islamic leadership education of Thariq as-Suwaidan is a leadership and leadership training program provided to the youngest of the most fertile human resources, step by step, in a training institute or course established specifically for this purpose, using various varied learning methods. The kind of education has really happened and will constantly happen in the reality of Indonesian society. The condition strictly shows the importance of the roles of Islamic scholars (ulama) in Islamic schools or Islamic institutions to perform and to shape their next generation to become the future leaders.

Abstract

Bioactive components are essential ingredients of functional foods, supplements, pharmaceuticals, etc. Sargassum cristaefolium brown seaweed, as an Indonesian marine resource, provides promising bioactive components. The present study was to extract the total bioactive components of S. cristaefolium with a microwave instrument. The extraction method was done serially using different polarity solvents (1st-stage: non-polar, 2nd-stage: semi-polar, Final-stage: polar). Yielded extracts were analyzed for bioactive compounds, functional groups, total phenolic and flavonoid, and antioxidative activities. The results showed that all staged extractions obtained bioactive compounds with various characteristics. However, the 2nd-stage extract was superior, and it exhibited the highest total phenolic and flavonoid (17.53±0.78 mg GAE/g, 72.64±3.01 mg QE/g), the richest volatile bioactive compounds (neophytadiene and phytol were dominant), and the predominant bioactive compound of antioxidative (oleoylethanolamide). Their functional groups confirmed the structure of antioxidative phenolic molecules: C―C stretching skeleton (phenyl/aromatic core), C―H stretching, C―H bending, and O―H stretching. The strongest primary (1439.84±63.02 µg/ml) and secondary (389.73±16.71 µg/ml) antioxidant activities were presented by the 2nd-stage extract. The efficiency of MAE and the potential of S. cristaefolium were promising for developing functional foods and pharmaceuticals that relate to antioxidants in the future.

Abstract

Seagrass (Syringodium isoetifolium) is a marine plant commonly found in Indonesian waters, known to contain bioactive compounds such as antioxidants, anti-inflammatory agents, and antibacterials. This potential makes seagrass a natural ingredient that can be utilized in developing skincare products, one of which is solid soap. This study aims to determine the effect of varying concentrations of NaOH and seagrass extract on the physical characteristics and antioxidant activity of solid soap. The seagrass extraction process was carried out using the ultrasound-assisted extraction (UAE) probe method with 50% ethanol as the solvent. Solid soap was formulated with variations in NaOH concentration (20%, 30%, and 40%) and seagrass extract concentration (0%, 5%, 7.5%, and 10%). Soap quality tests included measurements of moisture content, pH, and foam stability, while antioxidant activity was tested using the DPPH method to determine the IC50 value. The results showed that increasing the NaOH concentration and seagrass extract level tended to increase the moisture content and pH of the soap. The highest foam stability was obtained in soap with 20% NaOH and 10% extract, although the differences were not statistically significant. Antioxidant activity increased with the addition of seagrass extract, with the best result found in soap with 30% NaOH and 10% extract, which had an IC50 value of 1470.90 ppm. The solid soap produced met the solid soap quality standards according to SNI 3532:2021.
