With the increasing development of technology the more variety of books circulating on the internet. As is the recommendation system on online book sites that provide books relevantly and as needed with one's preferences. One alternative is GoodReads, a social networking site that specializes in cataloging books and users can share reading book recommendations with each other by rating, reviewing, and commenting. As a large book recommendation site, it has a lot of data that can be processed by applying machine learning methods, but still not known as the most accurate model. By using the right model, we can provide more accurate recommendations. Therefore, this study will analyze the data obtained from the www.kaggle.com namely the goodreads-books dataset. This study proposed a data mining classification model to get the best model in recommending books on GoodReads. The algorithms used are Decision Tree, K-Nearest Neighbor, Naïve Bayes, Random Forest, and Support Vector Classifier, then for model evaluation using accuracy, precision, recall, f1-score, confusion matrix, AUC, and Mean Error Absolute. The test results of several classification algorithms found that Decision Tree has the highest accuracy among the methods presented by 99.95%, precision by 100%, recall by 96%, f1-score of 98% with MAE of 0.05 and AUC of 99.96%. This is proof that decision tree algorithms can be used as book recommendations based on book categories on GoodReads.

Kurikulum 2013 yang diterapkan di Sekolah Dasar merekomendasikan model pembelajaran berbasis pendekatan saintifik yaitu discovery learning, project-based learning, problem-based learning dan inquiry learning. Sebagian besar guru di SD Negeri Gandekan No 230 Surakarta mengaku belum memahami keempat model pembelajaran tersebut sehingga perlu adanya pelatihan tentang model discovery learning dan project-based learning. Metode pelaksanaan pengabdian meliputi: (1) metode pendekatan yang dilakukan mulai tahap survei, perijinan, dan pemberian motivasi bagi guru yang akan mengikuti pelatihan (2) metode pelaksanaan program, meliputi tahap pendahuluan, tahap sosialisasi dan audiensi, tahap pelatihan, serta tahap evaluasi akhir. Hasil kuesioner tanggapan guru terhadap pengabdian yang telah dilakukan menunjukan bahwa materi pelatihan sangat diminati dan dibutuhkan guru dalam pengembangan pembelajaran abad 21 dan menunjang era revolusi industri 4.0. Guru merasakan manfaat dari kegiatan pengabdian kepada masyarakat yang dilaksanakan karena dapat menjadi wawasan keilmuan baru dalam pengembangan kegiatan pembelajaran di sekolah.

Academic data increases every year in line with the increase of students. Abundant data store is alsoan abundance of information. Data mining technology is a tool for extracting information on largedatabases and has been widely used in many domains. Predicting student performance (study evaluation) isan activity to determine a future state based on existing data. Data in the field of academic research hasbeen done with various methods and algorithms, but the use of algorithm SLIQ (Supervised Learning InQuest) has not been done.SLIQ is an algorithm developed by the IBM's Quest project team in 1996 for mining large datasets.SLIQ algorithm classify and predict the students performance, beginning with the data cleaning, conductedelection training and testing data. By calculating gini index of each attribute and then selecting thesmallest gini index data table is split according to the criteria until find the same class. From the results ofthe calculation process can produce a set of rules that can be used to predict student performance.From the experiment it can be concluded that the algorithm SLIQ with decision tree technique canbe used as an alternative in designing a system datamining applications. Tests conducted system showedthat the constructed model can be used to predict the performance of new students. The resulting accuracyof the model system in fact has a lower score than the accuracy of other applications that are used as acomparison of Tanagra. Advantages of the proposed system is in its design does not need complexcalculations in obtaining the gini index attributes.

This study analyzes the effect of receive, tariffs and quality perceptions of the learning process and service to increase interest. The formulation of the questions examined in this study were 1). What impact will influence the perception of market acceptance for graduates of interest in selecting majors AN? 2). What impact do perceptions influence the rates of interest specified AN AN chose? and 3). What impact will influence the perception of the quality of the learning process and service in the AN of interests to choose majors AN? Furthermore, variables and indicators of research is also based on previous research.A model has been developed and three hypotheses have been formulated to address this research problem. The sampling technique was purposive sampling and quota sampling. Respondents from this study amounted to 100 respondents, where respondents were students of the Department AN Semarang State Polytechnic. Data analysis tool used is Structural Equation Modelling (SEM) in AMOS 16.0.The results of this study data analysis shows the model and research results were well received, and further research is proving the influence of perception on the market acceptance of graduates AN interest in the Department of the AN is positive an  significant. Effect of tariff AN Perception of interest in the Department of the AN is not significant. Then the influence of the effectiveness of advertising on consumer buying behavior is positive and significant. And the influence of the learning process and service quality in the AN of interest in the Department is positive and significant.
