Abstract

The lubricating oil industry is one part of the oil and gas sector which is still one of the main pillars of economic growth in Indonesia. Sales predictions are needed by companies and policy makers as planning materials and economic development strategies to increase income in the future. Predictions that have a better level of accuracy can provide appropriate decisions. Various methods have been used, the Artificial Neural Network algorithm is one of the most widely used, especially in the Backpropagation (BPNN) structure which can predict non linear time series data. Backpropagation has been proven to have a better level of accuracy compared to econometric methods such as ARIMA. The integration of Backpropagation algorithm with other algorithms needs to be done to overcome the shortcomings and improve the ability of the National Land Agency itself. Particle Swarm Optimization (PSO) which is used as an optimization determinant of attribute weight values in the network structure of BPNN shows good results. After testing, BPNN without PSO has a Squared Error (SE) level of 0.012 and a Root Mean Aquared Error (RMSE) of 0.111. While BPNN with PSO has SE levels of 0.004 and RMSE of 0.059. This shows that there is a significant decrease in the error rate after the PSO algorithm is added to the BPNN structure which is 46.85%.

Abstract

The servicing done by jam'iyah 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.

Abstract

Klasifikasi warna citra digital untuk mendeteksi warna kulit atau bukan kulit merupakan hal yang sangat penting dalam dunia Computer Vision. Hal ini sangat membantu berbagai aplikasi dalam kehidupan nyata, seperti aplikasi deteksi wajah, gerakan tangan, sistem keamanan, deteksi penyakit kulit, pemblokiran konten dewasa, dan lain sebagainya. Warna merupakan komponen yang paling utama dalam hal mendeteksi warna kulit pada citra, oleh karena itu pada penelitian ini akan dilakukan eksperimen klasifikasi warna kulit pada piksel sebuah citra menggunakan ruang warna yang berbeda beda diantaranya, RGB, HSV, YCbCr, dan SCgCr dengan memanfaatkan algoritma pembelajaran mesin, yaitu KNN, Naïve Bayes, dan Random Forest. Pada penelitian ini, data yang digunakan merupakan data public Skin Segmented yang bersumber dari UCI dengan ruang warna RGB dan transformasi ke ruang warna lainnya, hasil klasifikasi yang dilakukan ternyata menghasilkan performa yang sangat baik, untuk algoritma KNN dan Random Forest selalu mendapatkan tingkat akurasi di atas 95% di semua ruang warna tersebut.

Abstract

The Murah Rejeki Building Store makes sales transactions every day, but these transactions are only used for reporting and data bookkeeping purposes. The Murah Rejeki Building Store has not conducted an analysis of the relationship between building material products purchased by consumers in the future. This study aims to process sales transaction data from consumer purchases using the Apriori Algorithm, which is one of the data mining processing methods. In this study, the authors use the Apriori Algorithm to find association rules by determining the Minimum Support and Minimum Confidence values. The results showed that with a Minimum Support value of 5% and a Minimum Confidence of 60%, 14 patterns of consumer purchase transactions were found. This information becomes very valuable in making decisions on preparing supplies of building materials and determining the layout of goods in TB. Cheap Fortune. The association rules formed can be used to plan sales strategies and layout of building materials at TB. Murah Rejeki.
