Abstract

The traditional alkali-catalyzed transesterification for the synthesis of biodiesel from the mixtures of soybean oil and waste cooking oil was carried out in a laboratory scale reactor. The effect of sodium hydroxide (NaOH) concentration as catalyst was investigated. The reaction temperature and stirring speed were maintained constant for 2 hours at 65oC and 600 rpm. For system equipped by agitation, and considered on rotational speed and length of rotor or in this case, magnetic bar, the G-force for this system was 10.06. The optimum condition was obtained at 0.75 wt% NaOH, mixing ratio of feedstock of 60%WCO-SO. The result showed increasing in the amount of NaOH gave a positive effect on a small percentage of waste cooking oil in mixture of feedstock, and negative effect on a greater percentage of waste cooking oil, it was due to that NaOH as alkali catalyst is very sensitive to qualities of feedstock, especially free fatty acid content of feedstock. Free fatty acid inhibited rate of transesterification reaction, and it caused side reaction; saponification reaction. It leads to complicated purification process and reduction of biodiesel as final product.

Abstract

Penerapan program keselamatan kerja secara utuh dapat meminimalkan risikoterjadinya kecelakaan kerja. Namun, pada kenyataannya banyak hambatan yangsering dihadapi, baik dari pihak kontraktor maupun dari pihak pekerja. Jadi dapat dikatakan bahwa kontraktor masih belummemandang masalah keselamatan kerja sebagai prioritas utama dalam mencapaitujuan perusahaannya, yakni kecelakaan nihil (zero accident).Tujuan dari penelitian ini antara lain mengetahui alasan pentingnya perusahaan kontraktor menerapkan program keselamatan kerja, identifikasifaktor-faktorpenghambat, dan mengetahui seberapa besar implementasi program keselamatan kerja padapembangunan Depo Elpiji Banjarmasin. Metode penelitian yang digunakan adalah deskriptif analisis berdasarkan kuesioner yang diberikan kepada Direktur, kepala proyek, karyawan/pekerja yangbekerja pada proyek pembangunan Depo Elpiji Banjarmasinsebanyak 40 responden. Hasil penelitian menunjukkan bahwa alasan pentingnya perusahaan kontraktor konstruksi menerapkan programkeselamatan kerja adalah nama baik perusahaan, kemanusiaan terhadap tenaga kerja, Undang-Undang dan Peraturan,dan alasan ekonomi. Hambatan yang terjadi pada penerapan Program Keselamatan Kerja adalah kurangnya kedisiplinan, kurangnya tingkat pendidikan dan pengetahuan adanya batas waktu (deadline) proyek, kurangnya kesadaran, bahasa komunikasi antara atasan dan pekerja, dan kurang membudayanya tentang keselamatan kerja pada para pekerja. Adapun Program Keselamatan Kerja pada Pembangunan Delpo Elpiji Banjarmasinyang telah dilaksanakan adalah pemahaman filosofi keselamatan kerja (67%), penetapan misi keselamatan kerja (90%), penetapan pimpinan divisi keselamatan kerja (77%), membentuk komite keselamatan kerja (77%), pelaporan segera setelah terjadi kecelakaan kerja (73%), memberikan pelatihan keselamatan kerja (70%), analisa sumber bahaya (77%), fasilitas/alat keselamatan kerja (83%), dan rancangan rencana darurat untuk keadaan bahaya (70%). Program keselamatan kerja berpengaruh terhadap tingginya tingkat kecelakaankerja yang terjadi dalam suatu proyek.
