When economic growth rises, the economic activity will also grow as in the case of insurance activities. One of the assets owned by an insurance company is the customer, hence the existence of a loyal or potential customer should be maintained by the insurance company. This study focuses on clustering or grouping the existing customer data in insurance companies using the Fuzzy C-Means (FCM) algorithm. This study uses data from the company for analysis and the results can be used as a basis for insurance companies in making decisions, especially those related to further insurance marketing to customers who have participated in insurance or who are still actively registered in payment insurance. Fuzzy C-Means can be used for clustering the customer datasets. It obtained 3 clustering results using Partition Coefficient (PC) in determining the validity index and the centers value was ranged from 0.5 to 1.0.</em></p> <p><em>&nbsp;</em></p> Nurfaizah Nurfaizah Fathuzaen Fathuzaen ##submission.copyrightStatement## 2021-03-24 2021-03-24 9 1 1 14 10.33558/piksel.v9i1.2359 Mobile-Based Technology for Data Management of Students Fieldwork Practices http://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/2360 <p align="justify"><em>Fieldwork Practices (PKL) is one of the activities in the vocational teaching and learning process which takes place in a direct business environment. The main purpose of implementing PKL is to introduce students to the real work. The implementation of PKL at SMK Ma'arif NU 1 Sumpiuh is carried out for 6 months which is divided into 2 implementation activities, namely 3 months in odd semester and 3 months in even semester. The purpose of this study is to provide a suggestion to facilitate the process of recording PKL student data both in odd and even periods. In addition, the proposed system also provides details on the location of PKL and provides if in the second stage of PKL implementation there are students who change the location. The PKL application has gone through the system functional testing phase and has been running according to the needs of the PKL activity process. The technology used in this study uses a mobile so that all activities both from the school, committee and students can be monitored in real time by all related parties.</em></p> Nandang Hermanto Alya Khansa Dzakkiyah ##submission.copyrightStatement## 2021-03-24 2021-03-24 9 1 15 28 10.33558/piksel.v9i1.2360 Expert System Application for Troubleshooting and Maintaining Epson L3110 Printer http://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/2429 <p align="justify"><em>Many organizations are making changes by using information technology to support their business activities.

However, the analysis of OPAC satisfaction is still rare. This study discusses the analysis of user satisfaction of OPAC. This study aims to determine the effect of content dimensions, accuracy, format, ease of use, and timeliness using the End User Computing Satisfaction (EUCS) method, a method for measuring the level of user satisfaction of a system. SPSS software was used to analyze user satisfaction. Sig. value of the content variable is greater than 0.1 (0.667), hence the hypothesis zero (H0) is accepted. It means that the content variable has no effect on user satisfaction. Sig. value for the accuracy variable is less than 0.1 (0.009), hence the H0 is rejected. Therefore, the accuracy variable has an effect on user satisfaction. Sig. value of the format variable is less than 0.1 (0.054), hence H0 was rejected, implying that the format variable has an effect on user satisfaction. Sig. value of the ease of use variable is greater than 0.1 (0.700), hence H0 is accepted, meaning that the ease of use variable has no effect on user satisfaction. Sig. value of the timeliness variable was 0.120 (&gt; 0.1), hence H0 is accepted. Therefore, the timeliness variable has no effect on user satisfaction.</em></p> Dista Trianisfi Nurfaizah Nurfaizah Eka Tripustikasari ##submission.copyrightStatement## 2021-03-24 2021-03-24 9 1 45 62 10.33558/piksel.v9i1.2493 Culinary Places Recommendation System in Bekasi City Using the Simple Additive Weighting Method http://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/2621 <p align="justify"><em>Bekasi city, based on data from the Central Bureau of Statistics (BPS) in 2018, shows the average Economic Growth Rate (LPE) of 5.82% from 2013 to 2016. Based on this growth, Bekasi city has business opportunities, for example culinary business, that has already spread around Bekasi city. The number of culinary places can cause problems when visitors determine culinary places that fit their criteria. Many visitors usually rely on information from relatives in determine culinary places, so this allows a mismatch between the recommendations of relatives and the criteria they want. Based on the problem, one of the proposed solutions needs to be made a method to support decisions that can provide recommendations in determining culinary places for visitors. The method used in determining the recommendation of culinary places is Simple Additive Weighting (SAW). In the process of calculating the method there are alternatives and assessment criteria used, there are several assessment criteria, namely price, number of menus, rating, and distance. The result shows the recommended alternative culinary place is the eighth alternative (A8) since the alternative has the highest preference value of 0.85. Therefore, the proposed system can be integrated in the culinary website to support user in choosing the culinary place.</em></p> Fata Nidaul Khasanah Herlawati Herlawati ##submission.copyrightStatement## 2021-03-24 2021-03-24 9 1 63 74 10.33558/piksel.v9i1.2621 Professional Clustering Based on the Graduates Profile Using K-Means Method http://jurnal.unismabekasi.ac.id/index.php/piksel/article/view/2264 <p align="justify"><em>The Information Systems department of Pelita Indonesia Institute of Business and Technology produces graduates with education knowledge to face the professional work, but the majority of students after graduating do not work according to their graduate profiles/educational background. This research aimed to help students in determining the appropriate graduate profile. The proposed system was built using the K-means method for the classification process of graduate profiles; hence, the results can be used as recommended profession to be taken. The data used in this study is the data of students of class 2016, and these results are compared with their current professional record data with the aim of knowing the percentage of professional suitability obtained with the current profession. After this research is tested, the results of the classification of the graduate profile can be obtained where there are 10 students in the administrator database cluster, 11 students of the web design and developer cluster, one student of the cluster information system manager, and 8 students of the cluster system analysis.

Discipline has also the most important element of good behavior, both as individual and social. A problem is when people on the road in finding the shortest path in order to get to the destination on time. Finding shortest path improves workers discipline and add value to employees. With the Dijkstra’s Algorithm, we can find the shortest route. The value on the edge of a graph can be expressed as the distance between nodes (roads). Through this proposed application, it easier for us to find the shortest route in a more effective time.</em></p> Fitri Yani Nurhasanah Windu Gata Dwiza Riana Muh.
