The minimization of unwanted technogenic impact is one of the important problems in oil and gas industry. Wastewater burial in deep aquifers is effective, widespread and the least polluting way to dispose of industrial wastes. The article presents methods of scientific knowledge (analysis, synthesis) data about hydrogeological conditions of wastewater burial in Cenomanian absorbing horizon in the territory of the Beregovoye field.

Analisis dilakukan menggunakan perangkat lunak WEKA. Penelitian dilakukan melalui pengumpulan data dari arsip atau  <em>database</em> biro Administrasi Akademik yaitu berupa data akademik mahasiswa fakultas teknik Universitas Darma Persada angkatan 2009 sampai 2014. Tahapan selanjutnya adalah <em>preprocessing</em> data yang dilakukan melalui analisis metode <em>clustering</em> menggunakan algoritma K-Means dengan terlebih dahulu menentukan jumlah <em>cluster </em>menggunakan metode Elbow dan interpretasi hasil. Berdasarkan hasil metode Elbow, jumlah <em>cluster</em> sebanyak 4 <em>cluster</em>. Berdasarkan hasil proses K-Means <em>clustering, </em>pembagian data pada masing-masing <em>cluster </em>adalah <em>cluster </em>1 berjumlah 556 data (26%), <em>cluster </em>2 berjumlah 414 data (19%), <em>cluster </em>3 berjumlah 189 data (9%) dan <em>cluster </em>4 berjumlah 1010 data (46%). Selanjutnya, yang memiliki lama studi lebih dari 4 tahun (lebih dari 8 semester) berada pada <em>cluster </em>2, <em>cluster </em>3, <em>cluster </em>4 sedangkan mahasiswa yang memiliki masa studi 4 tahun (8 semester) berada pada <em>cluster </em>1.</span></p><p class="Abstrak"><span lang="IN"><br /></span></p><p class="Abstrak"><em><strong><span lang="IN">Abstract</span></strong></em></p><p class="Judul2"><em>The duration of student study is one of the factors that influence the completing students' timeliness. Based on the policy of the National Accreditation Board of Higher Education (BAN-PT) in Regulation No. 4 of 2017 concerning the Policy for Preparing Accreditation Instruments, the duration of study is one of the benchmarks and evaluation elements in accreditation of study programs. From the Faculty of Engineering academic data, Darma Persada University, many students take more than four years of study. The duration of study is one of the problems of the study program manager in terms of academic performance. This study aims to analyze the old patterns of study by students of the Faculty of Engineering, Darma Persada University from academic data. K-Means algorithm clustering technique is used with the variables are majors, the area of origin, age, gender, Grade Point Average (GPA), Semester Credit Unit (SKS), year of entry and study duration. The Waikato Environment for Knowledge Analysis (WEKA) software is used as an analytic tool. The initial stage of research is through collecting data from archives or Academic sections, namely academic data from students of the Faculty of Engineering, Darma Persada University, 2009 to 2014. The next stage is preprocessing data through K-Means algorithm clustering analysis by first calculating many clusters using the Elbow method and result interpretation. From the Elbow method result, the number of clusters used is 4 (four) clusters. Based on the results of the K-Means clustering process, the data sharing in each cluster is cluster 1 (one) totaling 556 data (26%), cluster 2 (two) totaling 414 data (19%), cluster 3 (three) totaling 189 data (9%) and cluster 4 (four) totaling 1010 data (46%). Furthermore, those who have more than 4 years of study are in cluster 2, cluster 3, cluster 4 and students who have a 4-year study period are in cluster 1.</em></p><p class="Judul2"> </p><p class="Abstrak"><em><strong><span lang="IN"><br /></span></strong></em></p>
