This study aims to evaluate the impact of flight simulator training on enhancing situational awareness skills among aviation vocational education cadets. Situational awareness is crucial for pilots and aviation professionals to effectively respond to dynamic and challenging situations. Twenty cadets participated in this experiment, operating individually under the guidance of a flight instructor. The simulations were conducted at the Indonesia Civil Pilot Academy Banyuwangi simulation laboratory, configured as the ALSIM 172 Simulator. The testing scenario was designed to train cadets in handling challenging weather situations and improving their situational awareness while flying the Cessna 172 SP aircraft. The research data analysis utilized a quantitative approach and qualitative feedback from the cadets. The results of the study demonstrate that flight simulator training significantly enhances cadets' situational awareness skills, as evident from the increased scores and positive feedback regarding their improved understanding of changing situations. These findings underscore the importance of integrating simulator training into aviation vocational education programs to enhance situational awareness and ensure the safety and success of aviation operations.

The use of pottery pans lowers the roasting temperature and gives the product a more favorable taste. This study uncovers the role of pottery particle on chlorogenic acid (CGA) decomposition during roasting process. This study aims to design pottery pans and the roasting process that optimize the CGA content and quality of the coffee using Indonesian traditional ceramics from Banyuwangi, East java named Kreweng. The pottery was ground to between 74–1000 µm before activation. The elemental, phase, and morphology characterization performs on the coffee bean. The morphology characteristic of the pottery observed further using digital imaging technique to unravel the pores and boundaries. The impact of the pottery usage for coffee roasting also tested through coffee product pH measurement. The pottery morphology determines coffee product acidity. The smaller the pottery catalyst particle size results in more acid coffee. The pore and grain boundary concentration increases as the particle size decreases. At the same time, the Si/Al ratio was higher at the smaller catalyst particle size with higher porosity, grain boundaries, and absorption. The porosity and defects reveal the negatively charged faces of the pottery crystal edges. The charged faces revealed due to the pottery crystal vibration in response to heat during roasting process. The effectiveness of surface contact is greater due to the distribution of negative charges around the pores that attract OH- side of CGA. This interaction traps hydrogen proton on catalyst conductive surface. As a result, the CGA decomposes into several groups of atoms and molecules including H2 and CO2. The interaction with the catalyst transforms the macronutrient into aliphatic acid. Therefore, roasting media with a higher Si/Al ratio at smaller particle sizes with high micropores will increase the rate of decomposition and the acidity of coffee products.

Banyuwangi district has some Japanese caves and bunkers of World War II. The location of the objects are along the Banyuwangi coast as a maritime defense during the war. This structures can be used as education historical tourism object. There are many similar structures in other area that have been neglected and do not get enough preservation attention. This research is aimed to identify the potency of education historical tourism of Japanese caves and bunker in Banyuwangi. The research is done by field research for the observation of objects physical condition. It is also done by interviewing local government, historical actors and surrounding community. The result shows that the caves and bunker have a great potency but have not been used as education historical object.
