| Abstrak (Bhs. Indonesia) | Batuan induk batubara Formasi Balikpapan di Lapangan “X”, Cekungan Kutai, dikarakterisasi untuk mengetahui komposisi material organik, lingkungan pengendapan, dan tingkat kematangan termal melalui analisis petrologi organik terhadap tiga sampel batubara menggunakan mikroskop reflected light mengacu pada klasifikasi ICCP. Hasil penelitian menunjukkan dominasi maseral vitrinite sebesar 76,16–88,32%, diikuti inertinite sebesar 2,45–12,24% dan liptinite sebesar 0–7,52%. Berdasarkan diagram ternary Mukhopadhyay (1989), seluruh sampel diinterpretasikan terbentuk pada lingkungan forest swamp. Nilai reflektansi vitrinite (Ro%) sebesar 0,631–0,666% menunjukkan tingkat kematangan termal awal matang hingga puncak matang berdasarkan klasifikasi Peters dan Cassa (1994). Dominasi vitrinite mengindikasikan kecenderungan kerogen tipe III, sedangkan keberadaan liptinite menunjukkan kontribusi terhadap potensi pembentukan minyak. Hasil penelitian ini memberikan informasi dasar mengenai karakteristik material organik, lingkungan pengendapan, dan kematangan termal sebagai data pendukung kajian sistem petroleum dan evaluasi potensi hidrokarbon di Cekungan Kutai. |

| Abtrak (Bhs. Inggris) | Coal source rocks of the Balikpapan Formation in Field “X”, Kutai Basin, were characterized to determine their organic matter composition, depositional environment, and thermal maturity through organic petrographic analysis of three coal samples using reflected-light microscopy based on the International Committee for Coal and Organic Petrology (ICCP) classification. The results show that the samples are dominated by vitrinite macerals (76.16–88.32%), followed by inertinite (2.45–12.24%) and liptinite (0–7.52%). Based on the ternary diagram of Mukhopadhyay (1989), all samples are interpreted to have been deposited in a forest swamp environment. Vitrinite reflectance (Ro%) values of 0.631–0.666% indicate thermal maturity ranging from early mature to peak mature according to the classification of Peters and Cassa (1994). Vitrinite dominance suggests a tendency toward Type III kerogen, while the presence of liptinite indicates a contribution to oil generation potential. These findings provide fundamental information on organic matter characteristics, depositional environment, and thermal maturity to support petroleum system studies and hydrocarbon potential evaluation in the Kutai Basin. |
