In addition, it can also be seen from the form of PTS, PTS Accreditation and PTS Research Performance. This PTS grouping uses mixed data, namely numerical data and categorical data. The method used for grouping mixed data is the ROCK ensemble method (Robust Clustering Using Links) . The results of clustering numerical data obtained the optimum number of groups 3, on categorical data obtained the optimum group 4. After clustering each type of data and merging and clustering obtained the optimum group 3 with a threshold (θ) is 0.2. The results of each group are: low quality consist of 29 PTS, medium quality consist of 7 PTS, and high quality there is 1 PTS. The results of this research can be used to cluster private universities in Semarang City, so that it can be used as a reference for prospective students in choosing private universities in Semarang, and can be referenced to the Central Java LLDIKTI in determining the quality of private universities in Semarang City.  \n1. PENDAHULUAN  \nMenurut UU Nomor 12 Tahun 2012, pendidikan tinggi di Indonesia dikategorikan 2 jenis, diantaranya (1) Perguruan Tinggi Negeri (PTN) dan (2) Perguruan Tinggi Swasta (PTS) . Ketatnya seleksi penerimaan mahasiswa di PTN mengakibatkan tidak semua calon mahasiswa tertampung di PTN. Calon mahasiswa harus mendaftar PTS sebagai salah satu alternatif melanjutkan perguruan tinggi. Dalam memilih perguruan tinggi, calon mahasiswamempertimbangkan pilihan lembaga PTS yang dituju untuk mendapatkan pendidikan yang memberikan kemudahan dalam mencari pekerjaan setelah lulus. Untuk mendapatkan perguruan tinggi yang memiliki prospek ke depan maka calon mahasiswamempertimbangkan beberapa aspek, diantaranya (1) mutu SDM dan mahasiswa (input),(2) pengelolaan kelembagaan (proses),(3) pencapaian kinerja jangka pendek (output), dan (4) kinerja jangka panjang (outcome) . Di samping itu dalam pemilihan PTS, calon mahasiswa juga mempertimbangkan bentuk PTS, akreditasi PTS, dan kinerja penelitian yang dilakukanoleh PTS.  \nPenelitian ini dimaksudkan untuk memberikan gambaran cluster perguruan tinggi di Kota Semarang, sebagai panduan mahasiswa dalam memilih PTS. Pengelompokan PTS di Kota Semarang bertujuan untuk mengetahui ciri khas PTS dan kualitas PTS yang berbeda. Metode untuk mengetahui kelompok PTS berdasarkan ciri khas dan kualitas menggunakan data campuran dengan metode cluster ensemble, yaitu teknik pengelompokan yang menggabungkan hasil dari pengelompokan beberapa algoritma. Menurut He, et al (2005) dengan metode ini akan mendapatkan kelompok yang lebih baik.  \n2. TINJAUAN PUSTAKA  \nStatistika deskriptif adalah metode statistik yang berhubungan dengan pengumpulan data serta penyajian suatu informasi untuk memberikan data yang bermanfaat. Ada beberapa bentuk penyajian informasi diantaranya berupa grafik, gambar dan tabel. Penyajian informasi dapat menggunakan (1) rata-rata dan median dalam menjelaskan karakteristik data numerik. (2) bentuk grafik yang dapat menunjukkan frekuensi relatif data kategorik.  \nAnalisis cluste","cbCaiqIaxsVDcfzt","https://ap.wps.com/l/cbCaiqIaxsVDcfzt","pdf",355019,8,"Indonesian","# PENDAHULUAN\n# TINJAUAN PUSTAKA","[{\"question\":\"Apa tujuan penelitian pengelompokan PTS di Kota Semarang?\",\"answer\":\"Penelitian bertujuan memberikan gambaran cluster PTS dan membantu mahasiswa memilih PTS berdasarkan kualitas dari input, proses, output, dan outcome selama lima tahun.\"},{\"question\":\"Mengapa penelitian menggunakan data campuran dan metode ROCK ensemble?\",\"answer\":\"PTS dikelompokkan menggunakan data numerik dan kategorikal.
