Abstract

Ignition delay is an important parameter in diesel engine operation. It is defined as the time (or crank angle degree) between the start of injection and the start of combustion. Ignition delay should be kept as short as possible, otherwise diesel knocking can occur if the delay is too long. Many works have shown that increasing fuel cetane number may shorten the ignition delay. In conjunction with the BPBT "“ PPKS Biodiesel Project to utilize methyl ester palm oil (sawit) (MES) as an alternative fuel, several compositions of MES-conventional diesel fuel blends were tested. Cetane number of MES-diesel fuel blends were calculated to be higher than that of conventional diesel fuel. Hence, it was expected that the MES-diesel fuel blends would yield shorter ignition delay than pure diesel fuel. Engine tests were conducted to compare the performance of several blends of MES-diesel fuel. The results from in-cylinder pressure data, from which ignition delay was determined have confirmed this work. Furthermore, correlations between ignition delay, cetane number, and engine speed have been obtained in simple linear equations.Key words: Ignition delay, Cetane number, Biodiesel, Methyl Ester Sawit (MES), Direct injection.

Abstract

In the competitive digital era, companies are required to build an image as an attractive workplace to capture the attention of young talent, especially generation Z who will enter the job market. This study aims to analyze the effect of employer branding on the interest in applying for jobs of final year students in North Kalimantan, and to examine the role of social media as a moderating variable in the relationship. The study used a quantitative approach with an explanatory design through a survey method of 350 students from two universities, with data analysis using Structural Equation Modeling-Partial Least Squares (SEM-PLS) techniques. Employer branding was measured based on five dimensions of organizational attractiveness, while job application interest and social media exposure were measured using a Likert scale. The results showed that employer branding has a positive and significant effect on job application interest (β = 0.506; p = 0.002), and social media also has a significant direct effect on job application interest (β = 0.573; p = 0.000). However, the moderating effect of social media on the relationship between employer branding and interest in applying was not statistically significant (β = -0.088; p = 0.969). The findings conclude that while social media is effective as a direct communication channel, its success in strengthening employer brand image depends on the quality of content and consistency of the organization's narrative. The implication of this study suggests that local companies should strengthen their employer branding strategy and utilize social media more purposefully and contextually to attract young talent in frontier regions.
