The servicing done by jamiyah umroh hafas (a group which provide umrah service) still use conventional procedure, namely by using form paper during the registration which obliges pilgrims to meet with the organizer. Also in the next process all is done with a face to face model, so that for the management of pilgrims each package the officer must carefully sort it out. This greatly affects the service process, in which officers must be really careful to group installments from pilgrims, as well as prepare data for processing to passports and travel. Therefore, in an effort to provide optimal, fast and appropriate services for hafas pilgrims, it is necessary to adopt the Customer Relationship Management contained in e-business, as well as to engineer software that can facilitate officers in completing all pilgrims administrative who will go to makkah. Designing this system uses the V-Model method in which each stage is validated and verified so that the system that is produced really meets the needs of the users and helps the officers to better administer the needs of the pilgrims.

In this modern era, the technology is growing rapidly, the Internet is misled. This condition will be related to the service provider or commonly referred to as a server. Increasing the number of clients, the server also has to work heavier so that it often occurs overload. The Load Balancing mechanism uses the Least Time First Byte and Multi Agent system methods. This mechanism allows the server to overcome the number of users who perform service requests so that the load from the server can be resolved. This solution is considered efficient and effective because the request process on the information system will be shared evenly on multiple server back ends. The results of the research that can be proved if using this mechanism the server can work well when the request is from a user or client dating, this method successfully distributes the balancer evenly through the server backend. So the server is no longer experiencing overload. This can be proved when a system that has used the load balancing method with 300 connections generates a throughput of 123.1 KB/s as well as response time value of 4.72 MS and a system that does not use the load balancing method has a throughput of 108.4 KB/s as well as a response time value of 120.3 Ms. Therefore by implementing load balancing the performance of the system can always be improved.

The development of Virtual Reality technology is currently being developed even in every field of science, one of which is room mapping. Mapping digital space as a visualization medium has helped provide detailed information through the use of three-dimensional (3D) technology. To build a visualization of the room that is useful for the community, especially in the area of ??the hospital environment, especially hospital patients so that in fighting the disease patients remain in a state of enthusiasm, safe, comfortable and conducive supported by the environment. With the use of 3D technology, in building an interactive room design VR-Room Patient using the Unity 3D Engine is expected to help patients in choosing treatment rooms for Inpatient Hospital. The planned room description is the Presidential Suite Room, Deluxe Suite, Junior Suite and Class II. The results of this study in the form of visualization illustrated by each area, while the evaluation of the results of this study was conducted by asking respondents to fill in an assessment questionnaire on VR visualization using usability testing using the usability heuristic approach, and the usability test results obtained with an average value of 3.194 taken from the assessment of respondents on a scale of 1 to 4 where this explains that the VR-Room Patient application has a good level of reusability ie the average value is above 3.

Decision support system is the composition of a computer-based information system that functions as a supporter of decision making in an organization or company. Decision making in determining the provision of financing is very important because with the right decision the provision of financing can run well. Decision making method is useful for determining the best alternative from a number of other alternatives based on certain criteria, including the simple additive weighting method, Weighted Product and Technique For Order Preference by Similarity to Ideal Solution. A comparison of the methods of this decision support system is carried out to determine which method provides the highest accuracy value of the financing data for the El-Raushan BMT cooperative. Based on comparison of the SAW Method, Weighted Product and TOPSIS methods show that the Weighted Product method is more accurate than the simple additive weighting method Technique For Order Preference by Similarity to Ideal Solution. Judging from the value of the accuracy of the three methods with the highest accuracy WP (Weighted Product) method with an accuracy value of 94%.

As the age of the earth grows, so does the number of inhabitants who inhabit it. As we know, home or residence is one of the basic needs for humans. This is a very promising opportunity for housing developers, given the large number of residents, especially in Indonesia, who need housing. But there are some problems that must be faced by housing developers to choose the right place of development. One of them is the number of criteria that must be met for a place to be chosen. The purpose of this research is to facilitate and support in choosing housing construction locations. Decision Support System to be the right solution because complex calculations can be computerized to make it easier. Housing selection criteria are obtained based on interviews with PT Metro Perkasa Abadi for further processing. AHP and WP methods are suitable methods to be combined in solving existing problems. The AHP results are criteria weights, while WP generates location rankings.

Decision Support System (DSS) is a system that can help someone in making a decision to solve a problem. Weighted Sum Model (WSM) method and Weighted Product (WP) method are used in this system. The WSM method is the sum of the attribute rating multiplications with attribute weights. In this system, WSM method is used as a weight and will be used on the WP method. This weight is filled manually by the user and then calculated by the WSM method. Whereas the Weighted Product (WP) method is a method that uses multiplication to connect attribute ratings, and the rating must be raised first with the weight of the attribute. This system is used in the selection of college in the city of Malang. In the search process there are several criteria used, namely the number of computer department, tuition fees, campus environment, the number of scholarship programs and accreditation. These criteria are used as a reference for college grades used in the assessment section. The search procedure start when a user enters a criteria value that has been determined by the user. Furthermore, the value of the calculation is compared with the value already on data pattern. To find out whether the chosen university matches with the entered criteria, weight of criteria must be checked based on the university chosen by the user. The conversion value from input are compared by the value in the pattern data. The testing process in this study is by using a confusion matrix. Based on testing using the method confusion matrix, researchers obtained 72.50 % value of accuracy, 82,76% value of precision, 80% value of recall and 81,36% value of f-measure.

Having a healthy body is all living things and avoiding all kinds of diseases. Maintaining a healthy body can be done by exercising and maintaining a healthy diet. Excess eating unhealthy foods can foster disease or disorders in the body. One of them is hypertension. Blood pressure more than 140 mmHg and diastolic blood pressure more than 90 mmHg at double the difference within five minutes under conditions of sufficient recovery. Hypertension is a disease that has a high prevalence in Indonesia, which is 25.8%. The case of a patient with hypertension is inseparable from changes in diet. The wrong diet, coupled with inappropriate food ingredients can cause bad blood pressure. In this study, researchers will create a support system for selecting healthy foods for hypertension sufferers. In this study, researchers used the El Choices Traditionant La Realite Elemination method (ELECTRE) in order to find out healthy foods for people with hypertension. Based on this study, carried out various stages, nutritionists provide healthy food ingredients, then hypertension sufferers choose several food items to be consumed. Next, the food ingredients are calculated by the ELECTRE method and the last step is to find food ingredients recommended for hypertension sufferers.
