Pengaruh Penerapan Akad Isthisna Terhadap Minat Beli Masyarakat Di Perumahan Nakhil Garden Pawarengan Cikampek Barat

The need for housing is a basic need after the need for clothing and food. Housing Nakhil Garden Pawarengan Cikampek is one of the sharia property developers that provides ready-to-build residential products, using a non-bank sharia system in running their business, namely using an isthisna contract or advance reservation without any touch of usury. The purpose of this study was to determine the effect of the application of the Istishna contract on people's buying interest in the Nakhil Garden Pawarengan Cikampek housing, and to determine how much influence the application of the Istishna contract had on the public's interest in buying housing at Nakhil Garden Pawarengan Cikampek. This study uses quantitative methods, data collection is done by means of observation, interviews, distributing questionnaires and documentation respondent data. The population in this study are consumers who buy and are interested in buying housing with a sample of 40 people. The sampling technique is probability sampling using simple random sampling. The type of data used is primary data with a questionnaire data collection method. Then the analysis technique using simple linear regression data analysis. The results of this study indicate that the isthisna contract applied by Nakhil Garden housing has no effect on people's buying interest, this can be seen from the results of the regression test, namely the value of the coefficient of determination (R Square) generated is 0.187 from the correlation / relationship value ( R) of 0.432. so that it can be interpreted that the application of the Istishna contract has an influence on buying interest in Nakhil Garden Pawarengan housing by 18.7%, the remaining 81.3% is influenced by other factors not examined in this study

EV Smart Charging with Advance Reservation Extension to the OCPP Standard

An accurate management of the interactions among end user, electric vehicle, and charging station during recharge is fundamental for the diffusion of electric mobility. The paper proposes an extension of the Open Charge Point Protocol standard with the aim of including the user in the charging optimization process. The user negotiates with the central station a recharge reservation giving his/her preference and flexibility. The charging station management system provides different solutions based on user’s flexibility. This negotiation allows the optimization of the power grid management considering the user requests and constraints. The complete architecture has been designed, implemented on a web server and on a smartphone app, and tested. Results are reported in this work.

Real-Time Dynamic Pricing for Revenue Management with Reusable Resources, Advance Reservation, and Deterministic Service Time Requirements

In “Real-Time Dynamic Pricing for Revenue Management with Reusable Resources, Advance Reservation, and Deterministic Service Time Requirements,” Lei and Jasin consider a fundamental dynamic pricing problem when resources are reusable. In this problem, demand arrives according to a price-sensitive nonstationary rate, requesting a service that uses a combination of different types of resources for a deterministic duration of time. The resources are reusable in the sense that they can be immediately used to serve a new customer on the completion of the previous service. Moreover, different customers may have different service time requirement and may book the service in advance. The objective is to construct a dynamic pricing control that maximizes expected total revenues. They develop real-time heuristic controls based on the solution of the deterministic relaxation of the original stochastic problem and show that the proposed controls are near optimal in the regime of large demand and large resource capacity.
