USULAN PERENCANAAN PERAWATAN MESIN BOILER DI PT ADHI PERSADA BETON

The reliability of machines is one of the important factors in maintaining the smoothness of the production process in the manufacturing industry. PT Adhi Persada Beton (APB) Plant Sadang, which is engaged in the production of precast concrete and ready mix, heavily relies on boiler machines in the curing process of Concrete Spun Pile. However, the reactive maintenance approach has resulted in recurring damage, thereby reducing production performance and efficiency. Other issues include the unavailability of maintenance history records, delays in spare parts procurement, low technician competence, and the absence of structured SOPs.
This research aims to identify the types and causes of Boiler machine damage and to develop effective preventive maintenance strategies. Data were obtained through observation, interviews, and literature review. Analysis was conducted using the MTBF, MTTR, Availability methods, and the Fishbone Diagram. The results showed an MTBF value of 94.5 hours, an MTTR of 1.45 hours, and an availability of 69.7%.
The proposed solutions include the implementation of TPM, the 5S program, technician training, the preparation of SOPs, and the development of wind farm prototypes as an alternative energy source.

Keandalan mesin menjadi salah satu faktor penting dalam menjaga kelancaran proses produksi di industri manufaktur. PT Adhi Persada Beton (APB) Plant Sadang, yang bergerak dalam produksi beton pracetak dan ready mix, sangat mengandalkan mesin Boiler pada proses curing Concrete Spun Pile. Namun, pendekatan perawatan yang bersifat reaktif mengakibatkan kerusakan berulang, sehingga menurunkan performa dan efisiensi produksi. Permasalahan lain mencakup tidak tersedianya catatan riwayat perawatan, keterlambatan pengadaan suku cadang, rendahnya kompetensi teknisi, serta ketiadaan SOP yang terstruktur.
Penelitian ini bertujuan mengidentifikasi jenis serta penyebab kerusakan mesin Boiler dan menyusun strategi perawatan preventif yang efektif. Data diperoleh melalui observasi, wawancara, dan kajian pustaka. Analisis dilakukan dengan metode MTBF, MTTR, Availability, serta Fishbone Diagram. Hasil menunjukkan nilai MTBF sebesar 94,5 jam, MTTR 1,45 jam, dan availability 69,7%.
Solusi yang diusulkan meliputi penerapan TPM, program 5S, pelatihan teknisi, penyusunan SOP, dan pengembangan prototipe PLTB sebagai alternatif sumber energi.
