Strategic Role of Corporate Social Responsibility in Mitigating Air Pollution: A Case Study of PT Pertamina (Persero) Refinery Unit II Dumai
Full text linkThis study examines the role of Corporate Social Responsibility (CSR) in addressing environmental challenges, particularly air pollution, by PT Pertamina (Persero) Refinery Unit II in Dumai City. The research aims to assess how the company’s CSR initiatives contribute to mitigating negative environmental impacts while fostering sustainable development in its operational area. Employing a qualitative research design, data were collected through interviews and document analysis, then processed using NVivo 12 for thematic analysis. The findings reveal that PT Pertamina’s CSR implementation is structured around three core strategies: leadership commitment, regional outreach, and stakeholder engagement. Among these, stakeholder engagement was identified as the most significant factor in strengthening the effectiveness of CSR practices, especially in building community trust and promoting cooperative problem-solving related to air pollution. The study also highlights that CSR is not merely a legal or ethical obligation but functions as a strategic mechanism for social welfare improvement and long-term business sustainability. However, this research is limited by its qualitative focus, which does not include direct environmental data or broad community-based surveys. Future studies are recommended to integrate quantitative environmental metrics and expand stakeholder representation to enhance the reliability and policy relevance of CSR evaluations in the context of environmental management
Penerapan Lean Six Sigma untuk Peningkatan Kualitas Crude Palm Oil (CPO) di Pabrik Kelapa Sawit
Full text linkThis study aims to improve the quality of Crude Palm Oil (CPO) production at PT. Beurata Subur Persada through the Lean Six Sigma approach. The main problem faced by the company is the non-conformity of CPO quality to standards, especially Free Fatty Acid (FFA) levels, water content, and dirt content. To systematically identify and overcome the causes of defects, this study uses the DMAIC (Define, Measure, Analyze, Improve, Control) cycle combined with analysis tools such as Value Stream Mapping and Fishbone Diagram. The measurement results show that FFA levels are the most dominant type of defects with a DPMO value of 57,407 and a sigma level of 3.09, followed by water content and dirt content. Further analysis identified significant waste in the form of waiting, motion, defects, and overprocessing, which are caused by human, machine, method, raw material, and environmental factors. The Improve stage resulted in several recommendations for improvement such as limiting the storage time of FFB, operator training, regular machine maintenance, and using a digital recording system. The implementation of the solution showed an increase in sigma values and a decrease in the number of defects, indicating the success of the Lean Six Sigma approach in improving process capabilities. This research provides a real contribution to the application of data-based quality control methods in the palm oil industry, especially at the CPO processing level

PENGARUH METODE PENGGARAMAN BASAH TERHADAP NILAI SENSORI IKAN LAYANG ASIN (Decapterus sp.)
Full text linkThe potential of flying fish (Decapterus sp.) in Sangihe is relatively abundant, yet the catch frequently cannot be absorbed by the market in the peak season. One alternative to overcome the excess catch is to process it into salted fish products. The quality of salted fish is highly dependent on salt concentration and soaking time. This study aimed to observe the effect of soaking time on the sensory quality of flying salted fish. This research was an experimental research with two treatments for the duration of soaking in salt solution with each treatment repeated three times. The research stages included making salted fish using 20% salt concentration with 12 and 24 hours of soaking. Furthermore, the sensory assessment was carried out (SNI no. 8273: 2016) with the parameters of appearance, taste, odor, and texture. Storage was carried out for 30 days at room temperature before being tested for the presence of mold. The results showed that the treatment of soaking time only had a real influence on the sensory value of the appearance of flying salted fish. In contrast, the soaking time did not affect the sensory values of odor (8,47±0,6-8,53±0,4), taste (8,33±0,9-8,40±0,6), and texture (7,87±0,7-7,93±1,0). After being stored for 30 days at room temperature, it was seen that mold had grown on flying salted fish. The study results showed that the 12-hour soaking time had a better value than the 24-hour soaking time
