The latest accurate, precise, and trusted earthquake information is needed by all parties. For this reason, a system is needed to inform the latest earthquake so that the impact can be minimized. Departing from open data published by BMKG, which is an earthquake in real time, a push notification system for earthquake information was designed to the Android application using Google Firebase. Push notifications are adjusted for specific areas based on user wishes. When the user is in the vicinity of an earthquake-affected or surrounding area, or the location of an earthquake is in a city that is monitored by the user, the notifications that appear can be alerts. Whereas when the user is in a location that is not affected by an earthquake, the notification that appears is only as information that there is an earthquake in a certain area. After analyzing, designing, implementing and testing using the black box testing method, push notification system functionally produces results that are as expected.","PeriodicalId":32370,"journal":{"name":"IJISCS International Journal of Information System and Computer Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47907166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To control active smokers, regional governments are supported by the central government issuing regional regulations about Non- Smoking Area and Tobacco Advertising, Promotion and Sponsoring (TAPS). This paper aims to measure the level of implementation of non-smoking area and tobacco advertisements, promotional, and sponsor ban.

One strategy used in optimization is to determine the layout of the goods and keep the stock of goods available. Factors that influence the needs of market analysis is the level of frequency of consumers in buying an item. The number of transactions and data recording activities that still use the manual system, increasingly piling up only into expenditure and income records without any further processing. The method used in this analysis is the Apriori Algorithm which is commonly used in transaction data or commonly called Market Basket Analysis. Apriori algorithm is a type of association rule that can find a combination of items using two benchmarks, namely support and confidence. The concept of this association rule is to collect sales transaction data which will then be carried out by the mining process by determining the value of support and the value of trust. The results of this study can facilitate companies to increase sales turnover which refers to the results of processing sales transaction data using the Apriori Algorithm. ","PeriodicalId":32370,"journal":{"name":"IJISCS International Journal of Information System and Computer Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45005102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

National Standardization Agency of Indonesia often gives awards for each employee based on the achievements of an employee. With the award given, it is expected that employees will motivated to provide the best work results for the company. The current rating system for National Standardization Agency of Indonesia employees is still by distributing questionnaires, then the results of the questionnaire are recapitulated and ranked based on the highest score to the lowest value. The assessment process currently take a long time so the information obtained is not fast. With the existing problems, we need a system that can help the company in determining the best employees with predetermined criteria. Based on the problems that occur, it need decision support system that can help the company to choose the best employee. The method used in decision making is Simple Additive Weighting (SAW). Decision making with Simple Additive Weighting method is used for decision making using the weighted addition method. Calculations in employee evaluations are carried out directly by superiors with prescribed considerations. The system developed can determine the employees who have the best performance, and helpful for decision maker to make final decision.","PeriodicalId":32370,"journal":{"name":"IJISCS International Journal of Information System and Computer Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48189973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
