Abstract
Produksi susu sapi di Indonesia memiliki angka produksi yang sangat besar. Susu sapi mengandung berbagai macam nutrisi yang bermanfaat serta mudah dicerna bagi tubuh manusia. Susu merupakan komoditi yang cepat rusak jika tidak ditangani secara tepat. PT XYZ merupakan salah satu industri pangan yang mengolah susu sapi menjadi berbagai macam produk. Produk yang dihasilkan oleh PT XYZ yaitu susu ultra high temperature (UHT) dan susu kental manis (SKM). Boiler merupakan alat yang berfungsi untuk memanaskan air sehingga menghasilkan uap panas dan uap tersebut digunakan untuk proses sterilisasi susu sapi. Tujuan dari penelitian ini adalah menentukan nilai kapabilitas proses dan efisiensi pada mesin boiler 1 PT XYZ, mengidentifikasi penyebab terjadinya kegagalan proses, dan memberikan saran perbaikan. Data yang digunakan merupakan data yang berasal dari form mesin boiler unit I pada departemen engineering bulan Januari 2020 – Desember 2020 dengan parameter boiler pressure, boiler level, feed water temperature, feed water pressure, dan temperature out of economizer. Perhitungan nilai kapabilitas proses menggunakan indeks kapabilitas serta perhitungan nilai efisiensi menggunakan metode input – output. Berdasarkan hasil penelitian analisis kapabilitas proses pada parameter dengan parameter boiler pressure, boiler level, feed water temperature, dan feed water pressure nilai Pp dan Ppk kurang dari 1,33 (tidak kapabel). Pada parameter temperature out of economizer Pp lebih dari 1,33 (kapabel) tetapi Ppk kurang dari 1. Hasil rata – rata analisis efisiensi boiler unit I pada tahun 2020 yaitu sebesar 48,90%. Penyebab rendahnya nilai kapabilitas proses dan efisiensi yaitu karena fluktuasi beban boiler, kegagaln proses pada beberapa instrument boiler, dan kesalahan operator saat melakukan pencatatan. Saran perbaikan yang dapat diberikan yaitu diberlakukan maintenance secara berkala serta meningkatkan ketelitian operator.
English Abstract
Cow's milk production in Indonesia has very large production figures. Cow's milk contains a variety of nutrients that are beneficial and easy to digest for the human body. Milk is a commodity that spoils quickly if not handled properly. PT XYZ is a food industry that processes cow's milk into various products. The products produced by PT XYZ are ultra high temperature (UHT) milk and sweetened condensed milk (SKM). Boiler is a tool that functions to heat water to produce hot steam and the steam is used for the process of sterilizing cow's milk. The purpose of this study was to determine the value of process capability and efficiency in PT XYZ's boiler 1 engine, identify the causes of process failure, and provide suggestions for improvement. The data used is data that comes from the boiler unit I form in the engineering department in January 2020 - December 2020 with the parameters boiler pressure, boiler level, feed water temperature, feed water pressure, and temperature out of economizer. Calculation of the value of process capability using the capability index and calculating the value of efficiency using the input - output method. Based on the results of the process capability analysis research on the parameters with the parameters boiler pressure, boiler level, feed water temperature, and feed water pressure the value of Pp and Ppk is less than 1.33 (not capable). In the parameter temperature out of the economizer Pp is more than 1.33 (capable) but Ppk is less than 1. The average result of the efficiency analysis of boiler unit I in 2020 is 44.59%. The causes of the low value of process capability and efficiency are due to boiler load fluctuations, process failures on several boiler instruments, and operator errors when recording. Suggestions for improvement that can be given are periodic maintenance and increasing operator accuracy.
