ANALISIS KAPABILITAS PROSES PENYALURAN PRODUK BIOSOLAR DENGAN METODE STATISTICAL PROCESS CONTROL PADA PT PERTAMINA PATRA NIAGA INTEGRATED TERMINAL SEMARANG

Abstract

Abstrak

Mempertimbangkan spesifikasi yang telah ditentukan oleh pemerintah, PT Pertamina selalu
melakukan pengujian terhadap masing-masing produknya. Namun, pada beberapa kali pengujian,
terdapat parameter yang keluar batas spesifikasi. Oleh karena itu, untuk meningkatkan kualitas dan
menjaga standar produk, akan dilakukan analisis terhadap kapabilitas proses penyaluran produk
yang dihasilkan khususnya Biosolar menggunakan metode Statistical Process Control. Penelitian ini
bertujuan untuk mengidentifikasi kualitas Biosolar, mengidentifikasi nilai kapabilitas proses,
mengidentifikasi faktor yang menyebabkan permasalahan, serta memberikan saran perbaikan untuk
meningkatkan kapabilitas proses penyaluran Biosolar. Berdasarkan perhitungan kapabilitas proses,
didapatkan parameter Distilasi 90% dan Flash Point yang dinilai belum cukup kapabel dalam
menyalurkan produk Biosolar sesuai spesifikasinya. Penyebabnya kemudian dianalisis menggunakan
diagram fishbone dan failure mode and effect analysis (FMEA), di antaranya kualitas produk yang
diterima tidak sesuai dengan kualifikasi, serta mobil tangki dan awak mobil tangki tidak melakukan
pengecekan. Saran perbaikan yang dapat diberikan, yaitu memastikan produk yang dikirimkan sesuai
dengan spesifikasi sebelum dilakukan pengiriman, memberikan sistem reward dan punishment, serta
melakukan pelatihan untuk refreshment SOP dan meningkatkan skill.

Abstract

[Title: Process Capability Analysis of Biosolar Product Distribution Using Statistical Process
Control Method at PT Pertamina Patra Niaga Integrated Terminal Semarang] Taking into account
the specifications set by the government, PT Pertamina always tests each of its products. However, at
several times of testing, there are parameters that are out of specification limits. Therefore, to improve
quality and maintain product standards, an analysis will be carried out on the capability of the
product distribution process, especially Biosolar, using the Statistical Process Control method. This
study aims to identify the quality of Biosolar, identify the value of process capability, identify factors
that cause problems, and provide suggestions for improvements to improve the capability of the
Biosolar distribution process. Based on process capability calculations, were obtained Distillation
90% and Flash Point parameters which were considered not capable enough to distribute Biosolar
products according to specifications. The causes were then analyzed using a fishbone diagram and
failure mode and effect analysis (FMEA), including the quality of the products received did not meet
the qualifications, and the tanker and tanker crew did not check the equipments. Suggestions for
improvement that can be given are ensuring that the products delivered are in accordance with
specifications prior to delivery, providing a reward and punishment system, as well as conducting
training for SOP refreshment and improving skills.
