Abstract

Kampoeng Kopi Banaran is one of the trademarks that has been established since 2003 in Bawen, Central Java, Indonesia. Kampoeng Kopi Banaran itself houses several business lines under it such as Banaran Sky View Restaurat and Banaran Coffee Shop. Banaran Coffee Shop is one of the business units of Kampoeng Kopi Banaran which has been established since 2003 until now. To achieve this desire, of course, the Kampoeng Kopi Banaran must understand the right strategy so that the business carried out can be well accepted in the market. This research uses three interrelated data processing methods, namely the IFE and EFE matrices, IE matrices, SWOT matrices and QSPM matrices. The IFE and EFE matrices are used to analyze internal and external factors, the SWOT and IE matrices are used to determine alternative development strategies for Kampoeng Kopi Banaran and the QSPM method is used to determine the priority of the Kampoeng Kopi Banaran strategy. The Strengths-Opportunities strategy, which involves using strengths to seize opportunities through different approaches, is the best company development plan for Kampoeng Kopi Banaran. a. Support from Influencers b. Make use of social media and produce engaging and pertinent material for customers. The Integration of methods create an objective and measurable strategies successfully.

Abstract

The results of experimental research on marine thermal power plants using a shell and tube heat exchanger made of copper-tin (Cu-Sn) alloy are the main focus of this study. This study uses a heat exchanger Scale Model measuring 60 mm wide x 1 meter long. The system operated using a closed cycle and Organic Rankin cycle. A simulation study has been carried out using Ansys CFD software to model new heat exchangers, namely models A and B. The interaction between ammonia and hot water produces thermodynamic values in the form of an evaporator outlet temperature of 28°C in models A and B 260C. The weakness of model B is that the turbulent flow is divided into left and right sides so that heat loss occurs in the flow corner area. The seawater inlet temperature of 29°C can heat the working fluid from the ammonia flow inlet from 5°C to 28°C, resulting in saturated steam reaching 5-6 bar.
