Kesimpulan
� Pada Bagian Proses Pabrik Gondorukam dan TerpentinRejowinangun dalam menerapkan sistem keselamatankhususnya inherent termasuk dalam kategori inherent safety zone, sehingga potensi yang mungkin terjadi dapat di kurangidengan menerapkan inherent safety.
� Pencegahan potensi bahaya dapat dilakukan dengan� Pencegahan potensi bahaya dapat dilakukan denganmemperbaiki design proses agar lebih mudah dalampenggunaannya. Pencegahan lain adalah dengan penambahansafety tools dan penerapan safety behavior di setiapkesempatan pada tahap proses.
Saran
� Dengan adanya penilaian ini diharapkan pabrik gondorukemdan terpentin rejowinangun dapat mengambil kebijakan untukmenerapkan sistem keselamatan dan kesehatan kerja denganbaik supaya potensi bahaya dapat dikurangi maupun dapatdihilangkan khususnya pada bagian proses yang memilikipotensi bahaya yang lebih besar.
� Dengan adanya penilaian ini lembaga pendidikan khususnyabidang keselamatan kerja diharapkan bisa lebih aktif untukbekerja sama dengan industri menengah – kecil karena dalamkategori industri ini keselamatan kerja belum diperhatikandengan maksimal.
� Penilaian ini merupakan tahap awal dalam penerapankeselamatan kerja di industri diharapkan penilaian inidilanjutkan dan diperbaiki oleh peneliti tingkat berikutnya.
