Abstract

Data mining on process carried out to obtain information from a database or data that can be used to help solve the latest problems or solutions, data mining that is used in this paper is the process of merging by using K-Means solutions. K-Means is one of the techniques used to group non-hierarchical (bulk) data which is supported to provide existing data partition in the form of two or more groups. This method partitioned the data in groups so that the different characteristic data was grouped into other groups. The purpose of grouping this data is to support the objective functions arranged in the grouping process, which generally support variations between groups and take advantage of variations between groups. The agreed clustering was the grouping of non-commissioned police officers in the North Sumatra regional police, with the data collection used was the placement data within the North Sumater Regional Police HR. The procedure that is carried out in this research is the problem process to the design and testing of the program. The knowledge gained from the grouping of the Bintara Police of the National Police in the North Sumatra Regional Police HR is the 5th data Placement based on data collected related to the position of the Brig Ro Sarpras of the North Sumatra Regional Police, as well as related to the data analysis with the K-Intended Algorithm in the North Sumatra Police Brigade.

Abstract

This study aims to create a model that can classify book types based on several categories and analyze the accuracy results of the Support Vector Machine (SVM) method. This research begins with the stages of data collection, namely the dataset of books obtained from the library. Furthermore, the dataset will be categorized into several types. The next stage, after the data is collected, will be carried out in the pre-process stage. This pre-process stage aims to prepare data so that it is ready to be processed in the feature extraction stage. The pre-processing stage consists of text segmentation, case folding, tokenization, stopword removal, and stemming. Next, the feature extraction stage will be carried out which aims to explore potential information and represent words as feature vectors. The next stage is to separate the training data and test data. Then the classification process is carried out using the SVM multiclass method to get the final result of modeling. The resulting classification results will then be evaluated in order to obtain an accuracy value and then will be analyzed whether the resulting classification model is feasible to implement.

Abstract

Diseases and pests on cardamom plants is one of the diseases and pests that can seriously attack cardamom plants. Cardamom plant diseases and pests can be diagnosed through the symptoms that are currently being experienced by the cardamom or through its clinical picture, through these symptoms an expert system can be made to make a diagnosis. An expert system is a system that seeks to adopt human knowledge to a computer that is built to solve problems like an expert. The expert system made in carrying out the diagnosis uses the Naïve Bayes method. This method is a simple probabilistic-based prediction technique based on the application of Bayes' rules with the assumption of strong (naive) independence. In other words, in Naïve Bayes the model used is an “independent feature model”. This expert system was built using PHP and MySQL programming as a database. In this expert system the types of cardamom disease diagnosed consisted of aphids, leaf-eating caterpillars, stem borers, fruit and roots, leaf beetles, mosaics, late blight, root rot, and fungus, which consisted of 33 symptoms. While the results of the diagnosis will inform about the results of the diagnosis containing a list of symptoms entered, information on the results of regulations regarding diseases and pests that are attacking cardamom plants and information about possible treatments that can be carried out and treatment solutions.

Abstract

Kredit merupakan suatu sistem pinjam meminjam atas persetujuan yang telah disepakati diawal dengan phak bank atau institusi lembaga keuangan sejenis dengan nasabahnya. Dengan demikian analisa kelayakan pemberian kredit ini diharapkan dapat menganalisa solusi kesesuaian tingkat akurasi dalam sejumlah data yang sangat besar (big data) dengan melibatkan sebuah dataset yang nantinya akan dilakukan penambangan data dengan menggunakan tools rapid miner. Metode algoritma yang akan digunakan yakni metode data mining berupa Algoritma Naive Bayes Classifier. Klasifikasi data mining dapat membantu para analis kredit dalam hal menentukan signifikansi dan kelayakan pemberian kredit pada nasabah. Sehingga dari proses klasifikasi ini didapatkan berupa atribut penentu berupa kategori kelayakan dalam hal penentuan pemberian kredit kepada salah satu nasabah yang bersangkutan. Pengujian yang dilakukan yakni dengan menggunakan model confusion matrix yang melibatkan data training yang berbeda dalam hal jumlah atribut, dimana ekperimen pertama pengujian dilakukan terhadap 16 atribut data training kemudian ekperimen kedua pengujian dilakukan dengan melibatkan 9 atribut data training. Maka dari kedua eksperimen yang dilakukan akan diperoleh komparasi nilai akurasi, pengujian 16 atribut menghasilkan signifikansi akurasi 59,00% dan pengujian 9 atribut menghasilkan nilai akurasi sebesar 56,00 % sehingga dari kedua pengujian yang dilakukan dapat dipilih alternatif akurasi yang paling baik yakni pengujian dengan 16 atribut. Sehingga hasil dan output yang dihasilkan akan menghasilkan ketepatan pengujian atas suatu rekomendasi keputusan dalam membantu para profesional atau analis kredit di institusi keuangan dalam hal menentukan kelayakan pemberian kredit pada nasabahnya dengan bantuan algoritma yang digunakan untuk menyelesaikan suatu persoalan sehingga didapatkan pengidentifikasi terkait manakah yang layak atau tidak dikatakan sebagai penentuan pemberian kredit dengan mengacu pada penentuan kelas lancar atau bermasala

Abstract

Kegiatan penelitian menjadi salah satu kompetensi yang harus dimiliki oleh seorang guru yang profesional, karena salah satu guru yang berhasil (efektif) adalah bersifat reflektif. Guru yang demikian selalu belajar dari pengalaman, sehingga dari hari ke hari kinerjanya menjadi semakin baik. Namun kenyataan yang ada di lapangan, guru jarang melakukan kegiatan yang satu ini. Bermacam alasan disampaikan seperti: kurang memiliki kemamppuan meneliti/ kurang pengalaman, keterbatasan waktu karena penelitian sering kali harus meninggalkan jam mengajar, penelitian membutuhkan dana yang besar, dan sebagainya. Kenyataan di atas rupanya menjadi perhatian, sehingga akhirnya diciptakanlah formulasi penelitian yang sesuai untuk guru yakni Classroom Action Research atau yang lebih dikenal dengan Penelitian Tindakan Kelas (PTK). PTK akhir-akhir ini telah menjadi trend untuk dilakukan oleh guru sebagai upaya pemecahan masalah dan peningkatan kualitas pembelajaran. PTK merupakan suatu jenis penelitian yang dilakukan oleh guru untuk memecahkan masalah pembelajaran di kelasnya. Berdasarkan pendapat para ahli tersebut, dapat disimpulkan bahwa PTK merupakan penelitian yang dilakukan oleh guru di dalam kelasnya sendiri melalui refleksi diri dengan tujuan untuk memperbaiki kualitas proses pembelajaran di kelas, sehingga hasil belajar siswa dapatditingkatkan. Dengan demikian, PTK berfokus pada kelas atau pada proses pembelajaran yang terjadi di kelas, bukan pada input kelas (silabus, materi, dan lain-lain) ataupun output (hasil belajar). PTK harus tertuju atau mengkaji mengenai hal-hal yang terjadi di dalam kelas. Agar dapat lebih memahami makna PTK secara utuh dan benar, sebaiknya dikaji juga makna kelas dalam PTK. Dalam rangka peningkatan kualitas pendidikan, khususnya tingkat SMP di Kelurahan Simalingkar B berbagai program peningkatan kualitas guru telah dilaksanakan melalui pelatihan berkaitan dengan PBM, Uji Kompetensi Guru, MGMP, pelatihan di bidang evaluasi pembelajaran dan Penelitian Tindak lanjut dari pelatihan penelitian yang telah dilaksanakan. Penelitian Tindakan Kelas dipandang sebagai bentuk penelitian peningkatan kualitas pembelajaran yang paling tepat karena selain sebagai peneliti guru juga bertindak sebagai pelaksana PBM sehingga tahu betul permasalahan yang dihadapi, dan kondisi yang ingin dicapai. Namun antusiasme gurumasih kurang karena keterbatasan kemampuan dan pengalaman penelitian, sehingga serapan dana kurang optimal (sumber : Tim penyeleksi proposal PTK SG-SMP di PPM). Disamping itu karena keterbatasan pengetahuan dan pengalaman penelitian, hasil-hasil pelaksanaan PTK yang terlaksana masih kurang mencerminkan PTK, kebanyakan hasil penelitian tindakannya masih rancu dengan penelitian dengan analisis statistik. Oleh karena itu dipandang perlu untuk meningkatkan pemahaman, kemampuan guru SMP dalam melakukan Penelitian Tindakan Kelas agar upaya yang telah dirintis Dinas Pendidikan Kota Medan dapat budayakan di sekolah
