Abstract - The need for airplanes is increasing every day, this is due to the increasing number of passengers and cargo shipments from one area to another. Therefore, airlines need to provide optimal, safe, and efficient cargo and passenger transportation services so that the delivery of goods and passengers can run according to correct procedures. Opportunities in the business of transporting passengers and shipping cargo must be utilized properly by each airline by purchasing planes so that the shipping process from one area to another can quickly arrive at its destination. The purpose of this paper is to find the optimum value of the two aircraft between the Boeing 787-8 and the Airbus 330-900 in terms of the effect on the range, operational costs and to find out which aircraft is more profitable for operating costs on the Jakarta - Dubai route, using linear optimization. programming. Based on the results of the analysis that the optimum point for the calculation of linear programming optimization, the Boeing 787-8 aircraft obtained results (Max payload 41,075 kg, Fuel 6,657 kg, Max Fuel 101,323 kg) where these three results become a limitation for airlines to know the maximum usage of payload and fuel compared Airbus 330-900 aircraft obtained results at the point (Max payload 45,000 kg, Fuel 4,728 kg, Max Fuel 111,272 kg) so that the optimization results are obtained, for Boeing 787-8 aircraft with a max payload of 41,075 kg, max pax 359, max cargo 15,945 kg , compared to Airbus 330-900 with a max payload of 45,000 kg, max pax 460, max cargo 12,800 kg, so it can be concluded that the results of linear programming optimization and the calculation of the operational costs of the Boeing 787-8 aircraft are more optimal with a figure of Rp. 1,541,334,803.96 but in terms of revenue the Airbus 330-900 is bigger than the Boeing 787-8.

The increasing amount of people traveling in the city of Mataram causes the demand for satisfactory public transportation both in terms of quantity and quality. Damri Bus is one of the transportation that provides passenger public transportation services with one of the routes, specifically Lombok International Airport (LIA) - Mataram. The purpose of this research is to find out how much the Damri Bus passenger transportation rates are based on vehicle operating costs (VOC) route BIL - Mataram. The method used to analyze passenger transportation rates based on VOC is using the PCI (Pacific International Consultant) method. Based on the results of the analysis, it is known that the Damri Bus VOC is Rp 2,788,439, while the results of the data analysis based on the VOC obtained average rates in the Morning is Rp15,015, in the Noon is Rp 13,223 and in the Afternoon is Rp 42,262, with an average tariff is Rp 23,499 , 89. The actual tariff of Damri Bus routes BIL - Mataram is Rp. 30,000, the results show that the results of the tariff analysis with the actual tariff are still appropriate.

Abstract This paper studies the data-based polyhedron model and its application in uncertain linear optimization of engineering structures, especially in the absence of information either on probabilistic properties or about membership functions in the fussy sets-based approach, in which situation it is more appropriate to quantify the uncertainties by convex polyhedra. Firstly, we introduce the uncertainty quantification method of the convex polyhedron approach and the model modification method by Chebyshev inequality. Secondly, the characteristics of the optimal solution of convex polyhedron linear programming are investigated. Then the vertex solution of convex polyhedron linear programming is presented and proven. Next, the application of convex polyhedron linear programming in the static load-bearing capacity problem is introduced. Finally, the effectiveness of the vertex solution is verified by an example of the plane truss bearing problem, and the efficiency is verified by a load-bearing problem of stiffened composite plates.

Collection Point

Tembalang District has 206,271 residents, with 156,8 m3 amount of waste generated. Tembalang Sub-District has 18 waste collection point, 23 containers, and 7 transport vehicles to handle solid waste from the waste collection point to Jatibarang Landfill. The percentage of waste transportation services in Tembalang was 27%. There is some waste collection point that has not been able to accommodate waste generation from the Tembalang District residents. Road conditions, road types, and vehicle speeds of the waste transport route affect transporting waste and the remaining work time and the operational costs incurred. This research aims to plan a waste transportation system in Tembalang District by optimizing the work time and cost under the target desired by the relevant department. The average remaining work time is 2.28 hours, with a total of 21 trips/ day. Transportation routes are optimized using Network Analyst on GIS-based applications. Road conditions affect service time with an optimal average speed of 37.607 km h, which causes the addition of the number of trips after optimization increased to 34 trips/day with 31 containers. The average remaining work time is 1 hour. This optimization led to an increase in service percentage to 42%. Vehicle operating costs is increasing each year for about Rp. 694,262,870.53/year with a decrease in the price of fees of Rp. 1,983.59/householder/year due to the rise in service percentage.

Physical Paper

The use of physical paper in the business world today has become a consideration as a waste that can affect the company's financial cycle. The saving of using documents without using physical paper is one way to reduce the company's operating costs, especially for companies that have offices and also some factories in running their businesses. The operational process of non-physical documents is supported by the use of barcodes so that the use of paper is very minimal and management can reduce the company's operational costs to the maximum. This study aims to make observations and analysis of barcode usage related to the effectiveness and efficiency in terms of employee performance and especially financial savings. The results of the study show that in terms of operational expenses of the company that there are benefits of cost savings on physical paper purchases and also employee performance is quite significantly increased in carrying out daily operations because entering data can be done semi-automatically.
