The number of attributes can affect the performance of an algorithm. Several data mining methods that are widely used for classification include the K-Nearest Neighbor and naïve Bayes algorithm. The best algorithm for one data type is not necessarily good for another data type. It is even possible that a good algorithm will be horrendous for other data types. To overcome this issue, this study will analyze the accuracy of the K-Nearest Neighbor and Naïve Bayes algorithms for the classification of breast cancer. So that patients with existing parameters can be predicted which are malignant and benign breast cancer. This pattern can be used as a diagnostic measure so that the cancer can be detected earlier and is expected to reduce the mortality rate from breast cancer.","PeriodicalId":32370,"journal":{"name":"IJISCS International Journal of Information System and Computer Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49175388","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}

In project planning, information about the project achievement targets will be described in a series of activities and measurement of the clear target time for completion of work. If this concept of project planning can be applied in the development of micro-business sector in North Meruya Jakarta, so it will greatly assist entrepreneurs especially beginners in planning business operations in a measured and systematic manner. This will also be a solution for how the concept of electronic Supply Chain Management (e-SCM) system can be accommodated in the micro-business sector to increase profitability and economic growth. As we understand that micro-business entrepreneurs often find it difficult to survive in the problems of production, capital and business competition. So they need to understand the right production concepts and tools such as e-SCM. Therefore, this research will try to apply the concept of project planning method with e-SCM. e-SCM system design will use the method of Rapid Application Development (RAD).

However, in practice it is not easy and goes through a fairly long process. Likewise, the efforts of the government, especially the province of Lampung, are trying to carry out development through equal distribution of electrical energy to areas where the National Cross Border Center (PLBN) is located, such as Mesuji Regency, although it is still unstable and uneven throughout the village. The condition of the lack of electricity supply causes blackouts to occur frequently and in a relatively long period of time. This greatly affects community activities and is no exception in terms of education or at school, especially in the use of technology-based learning media and school administrative matters, such as filling out report cards and so on. Nowadays, filling out report cards must be done through technology-based applications that require electronic equipment such as laptops to use them. The design of the School Solar Panel System (SSPS) is intended in an effort to increase the availability of electricity in supporting teacher professionalism in carrying out learning activities.

A developed village will have a good impact on people's lives, both from the economy and the welfare of the community. The village head has an important role in running the government in rural areas.

With special autonomy regarding village development, the role of the village head becomes central and becomes the driving force for village development. To find out how well the village head is performing, it is necessary to have a breakthrough in measuring the village head's performance index in Pringsewu Regency. In measuring the performance of the Village Head, the criteria and weighting of the Simple Additive Weighting and TOPSIS methods are used. The sample was tested using eighteen villages spread across nine sub regency in the Pringsewu Regency. The application of two methods of decision support systems using Simple Additive Weighting and TOPSIS in measuring the index of Village Heads in Pringsewu Regency can trigger an increase in the performance of village heads to build the villages based on predetermined criteria.
