Illegal Levies as a Negative Element Contributing to The Decrease of The Tourism Potential on Madura
Get PDFAs revealed by the World Economic Forum, there is a correlation between corruption and tourism: the higher the level of corruption of a state, as reflected in the Corruption Perceptions Index of Transparency International, the lower the number of foreign tourists visiting the state. As such, a very strong correlation exists between the community development index, tourism, and the community’s legal awareness on the journey to the eradication of illegal fees. Illegal fees have to date been regarded as something normal in society. Illegal fees have become a regular in every sector, which must be ceased, and this holds true to the tourism sector as well. It is thus become essential to study the correlation between illegal fees in the tourism sector and the undermined tourism potential on Madura.Illegal fees have become part of the systems applied in Indonesia, including in the tourism sector. One of the reasons behind visitors’ disinterest in visiting a tourist attraction is the illegal fees someone imposes there, whether they be in the form of entrance fees or in the form of parking fees. The absence of a price standard allows some irresponsible persons to collect such fees as entrance and parking fees at tourist attractions variably according to the situation that arises in a given time.This paper uses a socio-legal research method to investigate directly into the relationship between illegal fees in the tourism sector and the undermined tourism potential on Madura. Primary data, collected through interviews, survey, and observation, were analyzed descriptively

The Selection of Learning Platforms to Support Learning Using Fuzzy Multiple Attribute Decision Making
Get PDFThe utilization of information technology in learning has functioned as a tool in the teaching and learning process during the Covid-19 pandemic. The need for the availability of a learning platform using LMS (Learning Management System) or free e-learning that is easily obtained from the public network (internet) makes the utilization of the learning platform indispensable for the teaching and learning process. Learning platforms available on the internet can also be used independently by students. However, not all existing learning platforms can be used as the appropriate means to improve the quality of education. The educator policies are needed to utilize the existing learning platforms so that learning objectives can be achieved. This study will analyze how to choose the right learning platform for an educational institution using SAW (Simple Additive Weighting)-based Fuzzy Multiple Attribute Decision Making (FMADM) method. FMADM is a method used to find the optimal alternative from a number of alternatives with certain criteria. The purpose of this study is to assist educators in deciding the most appropriate learning platform that can be used to support the teaching and learning process during the Covid 19 pandemic

Development of Learning Media Simulation of Automatic Garden Lights Using the Proteus Application
Get PDFWith so many garden lights, gardeners often struggle to turn on or turn on garden lights manually, this study aims to make it easier for park officers or gardeners to turn on or turn off garden lights practically. Automatic garden light is a lighting system that runs automatically, this system can use light sensors such as LDR (Light Dependent Resistor), photodiode and others. However, this circuit system can also use a timer that has been set in time when the circuit or garden lights will turn on and off, this can happen because there is an automatic switch circuit that utilizes the characteristics of one of the light sensors, namely the LDR sensor whose resistance value can change according to Light intensity. During the day, the resistance value of the LDR will be very high and even reach its maximum value of 10k , this makes the current flowing to the base of the transistor very small, to activate the transistor 2N3055 a minimum voltage of 0.9V is needed to the base of the transistor. Because the resistance of the LDR is very large, the voltage that enters the base of the transistor will be very small or even non-existent so that the transistor is like an open switch and does not flow current. One type of automatic switch that is widely used today is a light switch with a light sensor, where the switch will turn off and on automatically because it is affected by the intensity of the light around it. For example, at night, we don\u27t need to press the switch to turn on the lights, because the lights will turn on automatically. The results of this study indicate that the simulation experiment of garden lights using the Proteus application went well, the use of simulation using Proteus also aims to make it easier for us to understand an electronic component and how it works
The Study of Value-At-Risk Calculation and Back-testing Using the ARMA-GARCH Model Based on Stock Returns: An Overview
Get PDFStocks are investment instruments that provide returns but tend to be risky. The most important component of investing is volatility, where volatility is identical to the standard conditional deviation of stock price return. The important thing in investing in addition to return is a risk. Value-at-Risk (VaR) is a statistical method of estimating maximum losses. To evaluate the quality of VaR estimates, models should always be back-tested with appropriate methods. Back-testing is a statistical procedure in which actual gains and losses are systematically compared to appropriate VaR estimates. To evaluate the quality of VaR estimates, models should always be back-tested with appropriate methods. Back-testing is a statistical procedure in which actual gains and losses are systematically compared to appropriate VaR estimates. The goal of the study was to estimate the Autoregressive Moving Average-Generalized Conditional Heteroscedastic (ARMA-GARCH) model to determine Value-at-Risk and back-testing. ARMA is a combination of AR and MA models, while GARCH is a time series model with symmetrical properties. The method in this study is systematic browsing of libraries. Systematic library tracing is an attempt to identify, evaluate, and interpret all research relevant to a particular phenomenon.
