Abstract

Kegiatan pengabdian ini bertujuan untuk memanfaatkan limbah rumah tangga sebagai pupuk organik di lingkungan Sumber Nanas, Banyuwangi, sekaligus meningkatkan kesadaran lingkungan masyarakat. Metode yang digunakan meliputi pendekatan partisipatif dan persuasif melalui sosialisasi serta pelatihan pengelolaan sampah organik menjadi pupuk kompos dengan memanfaatkan teknologi Effective Microorganism-4 (EM-4). Hasil kegiatan menunjukkan bahwa masyarakat berhasil memperoleh pengetahuan dan keterampilan dalam mengelola limbah organik menjadi kompos yang bernilai ekonomis, dengan proses pengomposan yang lebih cepat dan efisien. Kegiatan ini disimpulkan mampu memberikan manfaat dalam mendukung keberlanjutan lingkungan serta membantu petani menyediakan pupuk ramah lingkungan yang murah, sehingga berkontribusi pada peningkatan produktivitas pertanian secara berkelanjutan.

Abstract

PT. Dian Swastatika Sentosa generates electricity through a private thermal power plant. This company produces steam and electricity for paper mills. The company hopes to meet its steam and electricity needs in 2023 with a boiler with a load capacity of 180 tons and a maximum capacity of 220 tons. However, from February to July 2023, that goal was not achieved. The most common problems faced by this company are the failure to conduct preventive inspections and timely machine maintenance, as well as the failure to carry out necessary repairs. Delays in machine repairs, which result in inconsistent machine downtime schedules to meet customer demand, leading to damage to boiler equipment, causing abnormal boiler operation and reduced steam production. This research aims to design equipment to withstand operational impacts using failure mode and effects analysis (FMEA) with the Soft Systems Methodology (SSM) and reliability-centered maintenance (RCM) techniques. The RCM method assists in identifying the processes that must be followed to guarantee that a machine or system performs as intended. RCM can also be used to design, choose, and create alternative maintenance methods that are focused on safety, operations, standards, and economics. For the entire problem in the investigation, a dynamic model is necessary. An analytical system is used in this model in order to recognize and duplicate the features of the overall system., as well as to provide repair solutions and address the burden of the problem. This research produces a presentation in the form of problem identification, causal loops, diagrams of machines that frequently experience failures, rich images of the causes and effects of the ball plate crusher liner damage, root cause definitions, and conceptual models for repair and maintenance. business productivity and debating process.

Abstract

Abstract. This study aims to determine the effect of Service Quality and Price on Customer Satisfaction at Rumiko Cafe in Tangerang Regency, both partially and simultaneously. The research method used is an associative quantitative method. The population in this study consists of Rumiko Cafe customers, with a total of 99 respondents selected using purposive sampling. Primary data were collected through questionnaires and processed using SPSS Version 25. The tests conducted include validity test, reliability test, classical assumption test, simple and multiple linear regression tests, correlation coefficient test, coefficient of determination test, and hypothesis tests (t-test and F-test). The results show that Service Quality and Price have a positive and significant effect on Customer Satisfaction, both partially and simultaneously. The multiple regression equation obtained is Y = 4.315 + 0.494X1 + 0.324X2. The correlation coefficient (r) value of 0.866 indicates a very strong relationship between the independent variables and the dependent variable. The coefficient of determination (R²) value of 0.751 indicates that 75.1% of the variation in Customer Satisfaction can be explained by Service Quality and Price, while the remaining 24.9% is influenced by other variables not included in this research model. Based on the simultaneous test, the calculated F value is greater than the table F value (144.482 > 3.09) with a significance value below 0.05, indicating that Service Quality and Price have a positive and significant simultaneous effect on Customer Satisfaction at Rumiko Cafe in Tangerang Regency. Keywords: Service Quality; Price; Customer Satisfaction.
