Abstract

Kesehatan dan Keselamatan Kerja (K3) adalah program yang dirancang oleh pekerja dan pengusaha untuk mencegah kecelakaan dan penyakit akibat kerja dengan mengidentifikasi potensi bahaya serta mengambil tindakan antisipatif. Penelitian ini mengukur penerapan K3 di batching plant PT. Dumai Jaya Beton dan menilai apakah ada perbedaan signifikan dalam penerapannya pada berbagai aspek, seperti Pelatihan dan Penggunaan Alat Pelindung Diri (APD), Pengawasan dan Perawatan Alat, serta Prosedur Operasi dan Keamanan. Survei dilakukan terhadap karyawan dan pekerja untuk mengumpulkan data. Hasil penelitian menunjukkan bahwa penerapan K3 secara keseluruhan berada pada kategori baik, dengan tingkat kepatuhan antara 71% hingga 88%. Uji ANOVA menunjukkan bahwa tidak ada perbedaan signifikan dalam penerapan K3 di berbagai aspek, menandakan bahwa standar keselamatan diterapkan secara konsisten di seluruh area kerja. Namun, beberapa aspek seperti penggunaan jalur transfer yang aman dan pemeliharaan alat rutin masih memerlukan peningkatan. Oleh karena itu, disarankan agar perusahaan mengoptimalkan program pelatihan, meningkatkan pengawasan dan pemeliharaan alat, serta memperbarui prosedur operasi dan keamanan untuk menciptakan lingkungan kerja yang lebih aman dan efisien.

Abstract

The research aims to obtain the characteristic of concrete using Spent Bleaching Earth (SBE) as substitute material on normal concrete. It is focused on compressive strength, setting time, and flexure strength. The percentage of SBE it used are 0%, 2%, and 4% of the cement weight. The result show SBE is not suitable to be a cement replacement because it show the decrease of compressive and flexure strength. But the setting time on SBE is slower than 0% SBE substitution and need more time to harden than normal concrete.Keywords : Spent Bleaching Earth, setting time, compressive strength, flexure strength

Abstract

Palm Crude Oil (CPO) production generates substantial waste, including Spent Bleaching Earth (SBE), which is difficult to recycle. This research explores the stabilization of SBE using seashells for use in concrete mixtures. The goal is to enhance concrete’s durability by utilizing the calcium content in stabilized SBE. In this study, we tested concrete with a design strength of 30 MPa. The tests included compressive strength on 150x300 mm cylinders, flexural strength on 600x150x150 mm beams after 28 days of curing, and water blasting resistance using two methods. The water blasting test assessed the concrete’s resistance to water pressure on 500 x 350 x 50 mm samples over three consecutive days. The results showed that concrete with a 7.5% SBE variation achieved a compressive strength of 42.06 MPa, higher than the design strength. Flexural strength increased by 4.67% with a 10% variation in SBE. However, the water blasting tests revealed that both concrete variations exhibited greater damage than normal concrete, indicating that while SBE improves compressive and flexural strength, it may reduce the concrete’s water resistance.
