Abstract

The location of the Laundry business is a means of building a business, namely the place where the business is founded. Competition in this Laundry business causes many things to be considered in choosing a Laundry business location because if you don't choose the right location for a Laundry business, it can cause many losses such as bankruptcy for business owners. For this reason, business owners need foresight when setting up their Laundry business. To assist entrepreneurs in making decisions regarding the selection of a Laundry business location, there is a system that can be used, namely SPK. Decision Support Systems (DSS) are the steps or stages in finding a solution to a problem where the process is carried out using a solution according to how the computer works. There are 2 methods used in this study, namely the MOORA and WASPAS methods. The MOORA method is a method that can be used in the completion and completion process of the DSS. This method has a working procedure that uses mathematical calculations. While the WASPAS method is to find the priority of the most suitable location choice by using weighting. Where the results of research using the Multi-Objective Optimization by Ratio Analysis (MOORA) method, that which meets the criteria as the best Laundry business location is alternative A1, namely Jalan Setia Budi with a value of 0.2780 as the first rank. Meanwhile, based on the WASPAS method that meets the criteria as the best Laundry business location, alternative A7 is Jalan Gatot Subroto with a value of 0.8407 as the first rank.

Abstract

The causative factor of rain can occur due to the air temperature in an area or also due to the volume of water carried by the clouds. Tomorrow's weather conditions are needed to draw up various plans. The people of medan city with the work of the majority of employees and traders need information about rainfall. For the past, rainfall forecasts depended heavily on the month, there was a dry season and a rainy season. But nowadays, rainfall is increasingly difficult to predict, so a model or system is needed that can accurately predict rainfall. In this study, it was explained about rainfall prediction using one of the ANN models to predict future rainfall called CNN-LSTM. CNN-LSTM is an artificial neural network system specifically designed to handle long-term time series data such as rainfall. In its architecture, the CNN-LSTM model uses 2 LSTM Hidden Layers consisting of 108 LSTM neurons in each layer. The activation function used is Tanh. The loss function used is Mean Square Error. The result obtained is a model that can better predict rainfall if the input data given to the model is getting longer which is marked by a smaller Root Mean Square Error value.

Abstract

Apart from being a congregational prayer center, the mosque can also be an information center that becomes everyone who visits it. The word congregation in prayer services has the meaning together and is led by the prayer priest. If in terms of praying, the priest holds a great responsibility for what he leads, for example, the priest should know anyone who is a follower of the imam (makmum) and should know the name, address of the congregation, even if their job. The Prophet Muhammad SAW 1500 years ago gave many examples of this in the hadith books. Rasulullah SAW led his prayers first paying attention to the congregation so that they straighten the rows (saf) and tighten them. The Prophet SAW once stroked the shoulders of the congregation while saying, straighten and tighten the rows (saf) by you because actually Satan will fill the empty rows. Apart from that, the Prophet SAW recognized each congregation, not only their names, but even every complaint that was experienced by each congregation. Therefore praying in congregation provides a solution for Muslims as long as the imam or leader can recognize and understand the current problems of the people. Along with the development of science and technology, an idea emerged on how to collect congregational data if it was collaborated with the IT world. Of course, this is by building a mosque information system that is able to record congregational visitors to the mosque. At the same time, this data can be used to track congregations if they want to be visited whose purpose is to invite congregational prayers to the mosque and provide encouragement to worshipers who are reluctant to come to the mosque

Abstract

Midwives are professional health workers who have graduated from midwifery education and are registered in accordance with statutory provisions. In practice midwives have attended special training to be able to provide services in the form of midwife care in the form of caring for childbirth and other services. However, the selection of the best midwife, especially at STIKES Indah Medan, is done manually where internal parties make random choices so that complaints are received by patients in their services. In solving this problem, it is better to use a system where selectors can choose the best midwife according to the desired requirements. The system is SPK with Rank Order Centroid weighting through the MOORA (Multi Optimization On The Basis Of Ratio Analysis) method which will produce a solution on the part of STIKES Indah Medan to choose one of the desired midwives
