Analisis of Digital Information Media for Education in the Purwodadi Botanic Garden Using Analytical Hierarchy Process
Full text linkPurwodadi Botanical Garden is an ex-situ plant conservation institution. According to Presidential Regulation No. 93 of 2011 the Botanical Gardens have the duties of conservation, research, education, environmental services. Wisata Flora is an educational package conducted by Purwodadi Botanical Garden, the activity depends on the Wisata flora tour guide and the information boards in the garden. The availability of tour guides is still limited, and the information boards supporting Wisata Flora are also limited. This was obtained from interviews with visitors who use the Purwodadi Botanical Gardens education service. Therefore, we need a breakthrough in the way of delivering information to support flora tourism activities by utilizing digital technology. Digitalization is an environmentally friendly alternative compared to through the addition of information in physical form. Some of the technologies that exist today can be used as an alternative delivery of information to visitors independently, namely Quick Response (QR) Codes, RadioFrequency Identification (RFID), and Location Based Service (LBS). Of the three alternatives required a priority of application in accordance with the needs and management capabilities of Purwodadi Botanical Gardens. The research will be conducted using the quesioner and interview method with the management of Purwodadi Botanical Gardens and analyzed using the Analytical Hierarchy Process method. The results of the analysis are expected to be valuable input for the management of Purwodadi Botanical Gardens
Company Profit Prediction Based On Forecasting Of Port Throughput Using Time Series-Adaptive Neuro Fuzzy Inference System
Full text linkAs a maritime country, ports play an important role in economic development in Indonesia. Throughput is an important factor affecting Port Profits. This prediction is needed in an effort to find out the company's prospects, help estimate the long-term profitability of representatives, predict earnings, and estimate risk in investment. In this research, forecasting data throughput will be carried out, such as container traffic, number of ships, export traffics, goods traffic, animal flow and passenger traffic for the next year using Time Series-Adaptive Neuro Fuzzy Inference System (TS-ANFIS) as an input parameter in the decision support system. Before predicting the benefits of the port using the ANFIS method, principal component analysis (PCA) was applied to reduce parameters that did not sufficiently affect the profits of the port. The data used are time series data from 2009 to 2018. From the system built it is expected to be able to provide good results in predicting the value of port throughput using TS-ANFIS and to predict profit values using the ANFIS method. The best results from profit prediction using ANFIS obtained R2 of 0.947, RMSE of 28524582.39, MAPE of 14.74% and MAAPE of 0.145. From the prediction results, it can be used as a reference for company projections in investing, managing cash flow, managing assets and global bonds
Equipment Leasing Model with Failure Tolerance Cost Using Game Theory
Full text linkIn this study the equipment lease contract, where two players, the lessor, lease the equipment to the user (lessee), if the equipment fails to exceed the tolerance agreed by both players during the lease period and needs to be repaired, it is considered detrimental to the lessee, because it results in a loss of potential revenue will be received from leased equipment. Therefore, the total income of the lessor in the lease contract may incur penalty costs as a consequence of the lessor for failure to maintain maintenance performance. We use Nash's game theory formulation to find a win-win solution between players where it is an equilibrium point for lessor and lessee. The results of this study are, when Lessee decides to maximize profits, which is the total potential profit gained by the lessee using leased equipment, and the lessor also decides to maximize their profits derived from the leased equipment by considering penalty cost as a cooperatively determined variable. The selected scenario is the percentage of the minimum penalty cost with the maximum level of equipment used
