Abstract

Penggunaan mesin yang terus-menerus menyebabkan kerusakan parah pada komponen mesin hydraulic press, seperti pompa, seal hydraulic, screw conveyor, bearing, dan laugher gantung. Akibat dari kerusakan tersebut, terjadi penurunan hasil produksi yang tidak sesuai dengan target perusahaan. Peneliti melakukan salah satu aktivitas perawatan dengan mengikutsertakan semua elemen perusahaan, menggunakan Overall Equipment Effectiveness (OEE) sebagai pengukuran dalam penerapan program Total Productive Maintenance (TPM) guna menjaga peralatan dalam kondisi ideal dengan mengeliminasi six big losses peralatan, yang merupakan hasil perkalian antara ketersediaan (AV), performance rate (PE), dan quality rate (RQ). Setelah melakukan perhitungan OEE, peneliti menganalisis faktor-faktor yang mempengaruhi nilai OEE menggunakan diagram cause and effect serta memberikan saran perbaikan melalui diagram tersebut. Hasil penerapan TPM menunjukkan nilai rata-rata OEE sebesar 35,41%, yang lebih rendah dibandingkan standar sebesar 84%. Analisis melalui diagram cause and effect menunjukkan bahwa faktor-faktor yang mempengaruhi nilai OEE adalah faktor manusia, material, metode kerja, dan mesin.

Abstract

In Islamic legal thinking when it is associated with social change so it has two theories, they are the theory of immortality and the theory of adabtabilitas. Based on the theory, Islamic legal thinking is developing now more than has tendency to follow the pattern of adaptability theory that is Islamic law as a law created by God for the humanity, and can adapt to the development of the times, so that he can be changed in order to realize in benefit of human being generally (maslahat al-ummah). Among of many mufties who follow the theory of adaptability, is Najamuddin Al-Thufi. The basic framework theory of adaptability is the principle of maslahat, which is a fundamental value for the sustainability of Islamic law in the concept of social change in decision of Islamic law. This written is a criticizes the concept of maslahat at-thufi which applies not only to the issue of law which nash is nothing , but also applies to the context which nash is exist as like in the matter of mu'amalah. When analyzed carefully, this concept can allow for a conflict between nash and maslahat, and the application of this concept afraided will apply to follow the passion and justify the haram tobe halal by on the pretext of maslahat.
