UPAYA DETEKSI KEBOCORAN BOTOL MINYAK CEM-CEMAN MENGGUNAKAN TEKNIK VACUUM, OVEN DAN SHIPMENT DI PT MARTINA BERTO TBK

ABSTRAK
Plastik memiliki keunggulan dibanding polimer lain diantaranya ringan namun kuat, transparan, tahan air serta harganya lebih murah. Pada praktik industri, penulis menemukan belum dilakukannya pengujian terhadap tiap sampel botol dan pump botol minyak cem-ceman. Tujuan dari penelitian ini yaitu menguji kebocoran terhadap botol dan pump botol minyak cem-ceman dengan metode vacuum test, oven test, dan shipment test. Teknik pengumpulan data dilakukan dengan metode observasi lapangan di ruangan R&D lebih tepatnya Packaging Development, melakukan kajian pustaka, melakukan pengujian yaitu vacuum test, oven test, dan shipment test, serta melakukan wawancara dengan manajer packaging development. Berdasarkan hasil pengujian, diperoleh informasi bahwa data yang diperoleh belum memenuhi standar yang telah ditetapkan, dimana tahap development kemasan diharuskan tidak ada kemasan reject ataupun Not OK. Beberapa faktor penyebab adanya kegagalan produk yang terjadi di PT Martina Berto yakni guncangan fisikal yang hebat saat dilakukan shipment test, serta ukuran gasket yang belum sesuai sehingga mengakibatkan kebocoran. Selain itu, upaya yang dapat diterapkan untuk mengatasi masalah kebocoran ialah dengan penambahan ketebalan dan diameter gasket pada botol minyak cem-ceman, penambahan jumlah gasket pada botol minyak cem-ceman, penetapan standar kekerasan gasket, serta peremajaan mobil distribusi.

ABSTRACT
Plastic has advantages over other polymers, including being light but strong, transparent, water resistant and less expensive. In industrial practice, the author noted
that tests had not been performed on every sample vial and pump vial of cem-ceman oil. The purpose of this research is to test the leakage of cem-ceman oil bottles and pumps using the vacuum test, furnace test and shipping test methods. In the R&D area, data collection techniques were performed using field observation methods, specifically Packaging development, literature review, tests, namely vacuum testing, oven testing, and transportation testing, as well as interview with the packaging development manager. Based on the test results, information was obtained that the data obtained did not meet the established standards, with the packaging development phase not requiring rejection or Not OK. Several factors contributed to the product failure at PT Martina Berto, namely the severe physical shocks during the transport test, as well as the inappropriate size of the gasket that resulted in a leak. In addition, efforts that can be made to overcome the problem of leakage are to increase the thickness and diameter of the gasket on the cem-ceman oil bottle, increase the number
of gaskets on the cem-ceman oil bottle, establish a standard set for gasket hardness, and rejuvenate the distribution car.
