Abstract

Air Traffic Controller at Rahadi Osman Airport Ketapang faces dilemma dealing with the obligations of Article 272, Law No. 1 of 2009 on Civil Aviation concerning the provision of navigation services and 429 concerning the sanctions to officials who do not have a navigation service certificate as if the conflicting views of airspace condition and navigation service authority there. This study aims to analyze the structure of controlled airspace and air navigation service authority with parameters : separation, cruising altitude distribution, efficiency and effectiveness of air navigation services. The results are the structure of  Aerodrome Traffic Zone airspace and aerodrome control tower services are not able to accommodate the development of air traffic which impact to the violation of Article 429. Restructuring the airspace into the Control Zone with the authority of navigation services as an Approach Control to accommodate the operational needs and the law’s legality is the solution.

Abstract

This research investigates the optimization of production processes through the redesign of logistics facility layouts. The research was conducted in a lubricant manufacturing industry that commands approximately 30% of Indonesia's lubricant market share. The factory has experienced bottlenecks in material and finished goods movement due to a threefold increase in production capacity, from 50-67 million liters to 176 million liters per year. This condition has led to wasted time and costs, necessitating improvements in material handling. This study aims to quantitatively measure and analyze the impact of facility layout redesign using the Systematic Layout Planning (SLP) method and compare it with Blocplan software simulation. The research methodology involves data collection, material flow analysis, and proposed layout design. Initial layout analysis revealed a total material handling cost (OMH) of Rp 2,800,474 per day and a rectilinear travel distance of 818.9 meters. Following the implementation of the proposed SLP layout, there was an efficiency increase of 15.56% in rectilinear distance (reducing to 691.4 m), 12.46% in OMH (reducing to Rp 2,451,421) , and 12.31% in moment (reducing to 15744). Meanwhile, the proposed Blocplan layout demonstrated more significant efficiencies: 51.33% for rectilinear distance (reducing to 398.5 m), 28.17% for OMH (reducing to Rp 2,011,558), and 28.95% for moment (reducing to 12756). Although Blocplan offers higher efficiency, the SLP method is suggested in this study given the field conditions and available space.
