Rekomendasi Intervensi

Mahasiswa ini memerlukan perhatian khusus. Disarankan untuk:

Konseling akademik untuk meningkatkan IPK
Bimbingan belajar intensif
Evaluasi beban SKS dan jadwal kuliah
Konsultasi dengan dosen pembimbing akademik
Monitoring ketat terhadap progress akademik
Intervensi dini untuk mencegah drop out

📋 Panduan Import Data Mahasiswa

Format Header CSV/Excel

File harus menggunakan header yang tepat dengan underscore (_):

"Nama","NIM","Program_Studi","Jenis_Kelamin","IPK","Kehadiran","Organisasi","Cuti","Lama_Studi"

Skema Database:

CREATE TABLE mahasiswa (
    Nama VARCHAR(100),
    NIM VARCHAR(20),
    Program_Studi VARCHAR(50),
    Jenis_Kelamin VARCHAR(1),
    IPK DECIMAL(3,2),
    Kehadiran DECIMAL(5,2),
    Organisasi VARCHAR(10),
    Cuti INT,
    Lama_Studi INT
);

No	Header CSV	Tipe Data	Contoh	Keterangan
1	Nama	VARCHAR(100)	Ahmad Fauzi	Nama lengkap mahasiswa
2	NIM	VARCHAR(20)	20210001	Nomor Induk Mahasiswa (harus unik)
3	Program_Studi	VARCHAR(50)	Teknik Informatika	Nama program studi
4	Jenis_Kelamin	VARCHAR(1)	L atau P	L = Laki-laki, P = Perempuan
5	IPK	DECIMAL(3,2)	3.45	Indeks Prestasi Kumulatif (0.00-4.00)
6	Kehadiran	DECIMAL(5,2)	85.50	Persentase kehadiran (0.00-100.00)
7	Organisasi	VARCHAR(10)	Ya / Tidak	Keaktifan organisasi
8	Cuti	INT	0	Jumlah cuti akademik (0-10)
9	Lama_Studi	INT	7	Lama studi dalam semester (7-12)

Contoh Data CSV:

"Nama","NIM","Program_Studi","Jenis_Kelamin","IPK","Kehadiran","Organisasi","Cuti","Lama_Studi"
"Ahmad Fauzi","20210001","Teknik Informatika","L",3.45,85.50,"Ya",0,7
"Siti Nurhaliza","20210002","Sistem Informasi","P",3.20,78.00,"Tidak",0,8
"Maria Dewi","20210003","Teknik Komputer","P",2.85,72.50,"Tidak",1,9

Catatan Penting:

Header harus persis: "Nama","NIM","Program_Studi","Jenis_Kelamin","IPK","Kehadiran","Organisasi","Cuti","Lama_Studi"
Gunakan underscore (_) untuk Program_Studi, Jenis_Kelamin, dan Lama_Studi
NIM harus unik, tidak boleh duplikat
Jenis_Kelamin harus L atau P (satu karakter)
IPK format: 3.45 (maksimal 4.00)
Kehadiran format: 85.50 (maksimal 100.00)
Organisasi: "Ya" atau "Tidak" (maksimal 10 karakter)
Cuti dan Lama_Studi harus bilangan bulat

Detail Algoritma C4.5

Atribut yang Digunakan:

IPK - Indeks Prestasi Kumulatif (threshold: 3.00)
Kehadiran - Persentase kehadiran kuliah (threshold: 75%, 85%)
Cuti - Jumlah cuti akademik yang diambil

Hasil Prediksi:

Tepat Waktu - Lulus dalam 4 tahun
Terlambat - Lulus lebih dari 4 tahun

Tingkat Confidence:

78% - 96% berdasarkan path keputusan
