Abstract

The quality of higher education services is a key factor in enhancing student satisfaction and loyalty amid intense competition, especially in private universities. A systematic evaluation of academic services is essential for improving educational quality. This study measures and evaluates the quality of services at a private university in Riau using an integrated model of Fuzzy Delphi, Fuzzy Service Quality, and Fuzzy Analytic Hierarchy Process (FAHP). A total of 47 service quality indicators from the dimensions of Physical Evidence, Reliability, Responsiveness, Assurance, and Empathy have been agreed upon by experts. Indicator A1 (completeness of facilities) has a weight of 0.0837 and a positive gap of 0.0508, while A5 (parking arrangement) has a negative gap of -0.1745. The Reliability dimension shows dissatisfaction with B1 (staff services) with a weight of 0.0545 and a gap of -0.2180. In Responsiveness, C1 (consultation time) has a gap of -0.1784, and C2 (friendliness) has a positive gap of 0.0441 with a weight of 0.2452. In Assurance, D1 (clarity of material delivery) has a weight of 0.2413 and a gap of 0.0502; D4 (accommodation of basic needs) has a gap of -0.1539. In Empathy, E1 (staff attention) has a weight of 0.2741 and a gap of 0.0462; E2 (management involvement) has a gap of -0.1715. These results identify critical areas and aspects that need to be maintained, serving as a basis for strategic decision-making to improve the quality of higher education services.

Abstract

Water Treatment Plant (WTP) Booster-B merupakan komponen kritis dalam sistem pembangkit listrik tenaga panas bumi di PT Supreme Energy Muara Laboh. Permasalahan misalignment pada motor yang terjadi Februari 2025 menyebabkan peningkatan getaran, kenaikan temperatur bearing, dan penurunan efisiensi energi. Penelitian ini bertujuan mengidentifikasi penyebab misalignment, menerapkan metode laser alignment sebagai solusi perbaikan, dan mengevaluasi efektivitasnya. Penelitian menggunakan metode observasi dengan pendekatan laser alignment dan analisis fishbone diagram 5M+1E. Pengambilan data meliputi pengukuran kecepatan putaran (2925 RPM), diameter kopling (80 mm), dan parameter jarak menggunakan laser alignment Profteknik. Hasil penelitian menunjukkan penyebab utama misalignment adalah kesalahan instalasi, kondisi kopling tidak presisi, soft foot, serta pengaruh getaran dan suhu operasional. Sebelum perbaikan, vertical offset mencapai 0,07 mm (melebihi batas acceptable 0,06 mm). Setelah penyetelan dengan pengurangan shim 0,05 mm, vertical offset turun menjadi 0,05 mm dan horizontal offset -0,03 mm, semua parameter berada dalam kategori acceptable hingga excellent. Metode laser alignment terbukti lebih akurat dan efisien, berhasil mengembalikan kondisi alignment dalam batas toleransi, meningkatkan performa motor, mengurangi risiko kerusakan, dan memastikan keandalan sistem operasional.
