Abstract

The purpose of this study was to determine the role and government of the village towards the Millennial Generation in Laut Dendang Village. The method used in this study is a qualitative method with data collection techniques in this study using the methods of observation, interviews, and documentation. This is in accordance with the research objective to analyze the role of the village government of Laut Dendang towards the millennial generation. Based on the results of the study, it can be concluded that the role of the Laut Dendang Village Government towards the Millennial Generation in the village is to be able to manage public finances, mobilize community participation and the younger generation in the implementation of development, mobilize community participation and the younger generation in creating public order and security, and follow involve the younger generation in empowerment. Therefore, the village government includes the role of the millennial generation in the development of various tours in Laut Dendang Village, with the aim that the millennial generation can learn to manage and even improve tourism so that it develops more rapidly.

Abstract

The aim of this research was to investigate the influence of catalyst on the flash point, viscosity, density, and iodine value of biodiesel. The raw material used in biodiesel production was waste cooking oil. The transesterification process was employed by reacting the catalyst and methanol, followed by mixing them with the waste cooking oil simultaneously. The catalyst concentration variations used in this study were 0.25% and 0.5%. The resulting transesterification mixture was left to settle for approximately 10 minutes. The biodiesel and glycerol were separated after settling, and the biodiesel was washed with distilled water at a temperature of 50°C and then evaporated at 100°C. The flash point test results for catalyst concentrations of 0.25% and 0.5% were 58°C and 48.5°C, respectively. The viscosity test results for catalyst concentrations of 0.25% and 0.5% were 4.567 x 10-6 m2/s and 4.625 x 10-6 m2/s, respectively. The density test results for catalyst concentrations of 0.25% and 0.5% were 889 kg/m3 and 888.3 kg/m3, respectively. The iodine value test results for catalyst concentrations of 0.25% and 0.5% were 112.2 g I2/100g and 114 g I2/100g, respectively. Based on the test data, the flash point, viscosity, density, and iodine value were obtained. The test results indicated that the flash point values from both experiments did not meet the biodiesel quality standards. However, the viscosity and density test results from both experiments met the biodiesel quality standards and were suitable for use. Regarding the iodine value test, the characteristics of the biodiesel from both experiments did not fully meet the biodiesel standard, although the results obtained were not significantly different from the quality standards set by the Ministry of Energy and Mineral Resources
