Abstract

Abstract This research aims to analyze the financial performance of PT Indofood Sukses Makmur Tbk using the Economic Value Added (EVA) and Market Value Added (MVA) approaches as indicators of the creation of economic value and market value for shareholders. The data used is secondary data from the company's financial reports. The analysis results show that EVA has a positive value during the observation period, indicating that the company is able to create added value after covering its capital costs. In 2021, the EVA value reached the highest of Rp 9,393,320.53 which was influenced by high NOPAT and low capital charges due to a decrease in the WACC value. On the other hand, in 2020 the lowest EVA value was Rp 4,255,975.31 which was caused by high capital costs which reduced the company's economic added value. Meanwhile, the MVA value was positive during the observation period, although it experienced fluctuations. The highest MVA occurred in 2020 amounting to Rp 2,029,249,299,456 and the lowest in 2023 amounting to Rp 816,663,035,109 due to changes in share prices and the number of shares outstanding. Overall, PT Indofood Sukses Makmur Tbk shows the ability to create economic and market value, however MVA fluctuations indicate the need for a more optimal strategy in maintaining company value. Therefore, companies need to increase capital cost efficiency, strengthen growth strategies, and maintain share price stability in order to maintain investor confidence and create sustainable value. Keywords: EVA, MVA, Performance, Value AddedAbstrak Penelitian ini bertujuan untuk menganalisis kinerja keuangan PT Indofood Sukses Makmur Tbk menggunakan pendekatan Economic Value Added (EVA) dan Market Value Added (MVA) sebagai indikator penciptaan nilai ekonomi dan nilai pasar bagi pemegang saham. Data yang digunakan merupakan data sekunder dari laporan keuangan perusahaan. Hasil analisis menunjukkan bahwa EVA benilai positif selama periode pengamatan, menandakan bahwa perusahaan mampu menciptakan nilai tambah setelah menutupi biaya modalnya. Tahun 2021, nilai EVA mencapai tertinggi sebesar Rp 9, 393,320.53 yang dipengaruhi oleh tingginya NOPAT serta rendahnya capital charge akibat penurunan nilai WACC. Sebaliknya, pada tahun 2020 nilai EVA terendah sebesar Rp 4,255,975.31 yang disebabkan oleh tingginya beban biaya modal yang mengurangi nilai tambah ekonomi perusahaan. Sementara itu, nilai MVA positif selama periode pengamatan, meskipun mengalami fluktuasi. MVA tertinggi terjadi pada tahun 2020 sebesar Rp 2,029,249,299,456 dan terendah pada tahun 2023 sebesar Rp 816,663,035,109 akibat perubahan harga saham dan jumlah saham beredar. Secara keseluruhan, PT Indofood Sukses Makmur Tbk menunjukkan kemampuan dalam menciptakan nilai ekonomi dan pasar, namun fluktuasi MVA mengindikasikan perlunya strategi yang lebih optimal dalam mempertahankan nilai perusahaan. Oleh karena itu, perusahaan perlu meningkatkan efisiensi biaya modal, memperkuat strategi pertumbuhan, serta menjaga stabilitas harga saham guna mempertahankan kepercayaan investor dan menciptakan nilai berkelanjutan.Kata Kunci: EVA, MVA, Kinerja, Nilai Tambah

Abstract

This study was motivated by the availability of problem-based buffer solution e-modules that have been tested for validity, practicality, and effectiveness, but have not yet been tested for their effect on learning outcomes in the cognitive domain, so the e-modules cannot yet be disseminated. This study aims to reveal the effect of using problem-based e-modules on the cognitive learning outcomes of high school students in phase F. The type of research used was a quasi-experiment with a nonequivalent control group design. The research population was grade XI Fase F students at SMAN 3 Bukittinggi. The sample was selected using purposive sampling techniques, with grade XI F2 as the experimental class and grade XI F4 as the control class. The research instrument consisted of a written test with 25 multiple-choice questions that had been pilot-tested. The data analysis techniques used in this study were normality test, homogeneity test, and t-test. Based on the data analysis results, it was found that both sample classes had normally distributed data with Dcalc < Dtable and had homogeneous variance with Fcalc < Ftable. The results of the hypothesis test using the t-test at a significance level of 0.05 showed that tcalc (4.60) > ttable (1.67). These results indicate that the learning outcomes of the experimental class were significantly higher than those of the control class. Based on the research results, the use of problem-based e-modules on buffer solutions had a significant effect.

Abstract

Buffer solutions are a topic taught in the even semester of Grade XI Phase F in Indonesian senior high schools (SMA/MA). This subject is inherently complex and involves extensive mathematical calculations, often making it difficult for students to comprehend. Based on interviews with teachers and a questionnaire distributed to students at the UNP Laboratory Development Senior High School, it was found that 87% of students reported difficulty in understanding the concepts of buffer solutions. The instructional materials used were limited to printed formats and failed to capture students attention. One of the key components of successful learning is the quality of instructional materials provided to students. Therefore, a buffer solution e-module based on Problem-Based Learning (PBL) integrated with the Teaching at the Right Level (TaRL) approach was implemented. Although this e-module had undergone validation for content quality and practicality, its effectiveness had not yet been tested, and as such, it was not ready for widespread adoption. The purpose of this study was to evaluate the effectiveness of the buffer solution e-module based on PBL integrated with TaRL in improving student learning outcomes. The research employed a pre-experimental method using a one-group pretest-posttest design. The sample consisted of 30 students from Grade XI F5, selected using purposive sampling. The instrument used in this study was a multiple-choice test that met criteria for validity, discriminating power, reliability, and appropriate difficulty level, indicating good item quality. Data analysis yielded an N-Gain score of 0.713, which falls into the high category. The statistical analysis of the hypothesis test using the paired sample t-test yielded a calculated t-value of 19.489 > table t-value of 1.699. Based on these findings, it was proven that the e-module on buffer solutions based on PBL integrated with TaRL is effective in improving student learning outcomes.

Abstract

This study examines the dualism of creativity and innovation among craft industry players in South Sulawesi, focusing on the tension between traditional imagination and the influence of social media. In the digital era, the local craft industry faces the challenge of maintaining authenticity while meeting modern market demands. The research analyzes how these two approaches shape creative processes, product innovation, and business strategies. Using a qualitative methodology with in-depth interviews, two groups of craft players were identified: traditionalists, who rely on imagination and reject digital influences, and digitalists, who actively use social media for inspiration and business development. The findings reveal that traditionalists emphasize authenticity and artistic integrity, with innovation occurring incrementally. In contrast, digitalists integrate tradition with global trends, using social media as a tool for market-oriented innovation and business sustainability. These results contribute theoretically by enriching the literature on creativity dualism in the creative industry and offer practical implications for craft practitioners. The study suggests the adoption of hybrid strategies that combine the strengths of tradition with digital opportunities. Future research is recommended to explore business models that successfully navigate this dualism and ensure both cultural preservation and market competitiveness.
