One of the highest contributors to death is bleeding during childbirth. Stage III is a stage of labor that has a relatively short duration, can endanger the mother's life because of the increased risk of bleeding and lead to maternal death. This study aims to determine the relationship between maternal age and the duration of placental separation in the third stage of labor. This research method uses a correlational study research design with a retrospective approach. The sample of this study was 138 mothers who met the inclusion criteria. Using a purposive sampling technique. The data collection method used secondary data from medical records and partograph sheets, then the data were analyzed using Chi Square. The results of this study were almost all (77.5 percent) of the mother's age were 20 until 35 years old, while almost all of the time (82.6 percent) of the placenta was detached was not long. Statistical test chi square obtained a value of p more than 0.05 that H0 is rejected, meaning that there is a relationship between maternal age and the incidence of prolonged placental detachment in the third stage with an OR of 5.7, the maternal age at risk will cause the incidence of prolonged placental detachment 5 , 7 times more than the age of mothers who are not at risk. It is hoped that mothers, especially mothers who are at risk of age, understand the importance of planning for childbirth so as to prevent complications during delivery, especially the problem of the length of time the placenta is released. Keywords: Maternal Age, Length of Placenta Release. Abstrak: Angka Kematian Ibu (AKI) di Indonesia masih tergolong yang tertinggi di Asia Tenggara serta masih jauh dari target global SDG (Sustainable Development Goals). Penyumbang kematian tertinggi salah satunya yaitu perdarahan pada persalinan, Kala III merupakan tahapan persalinan yang memiliki durasi relatif singkat, dapat membahayakan nyawa ibu karena adanya peningkatan resiko perdarahan dan berujung pada kematian ibu. Penelitian ini bertujuan untuk mengetahui hubungan usia ibu dengan lama pelepasan plasenta pada kala III persalinan. Metode penelitian ini menggunakan desain penelitian studi korelasional dengan pendekatan retrospektif. Sampel penelitian ini sebanyak 138 ibu bersalin yang memenuhi kriteria inklusi. Menggunakan teknik sampling purposive sampling. Metode pengumpulan data menggunakan data sekunder dari rekam medis dan lembar partograf, kemudian data dianalisis dengan menggunakan Chi Square. Hasil penelitian ini hampir seluruh (77,5 persen) usia ibu merupakan usia 20 sampai 35 tahun, sedangkan lama pelepasan plasenta hampir seluruhnya (82,6 persen) pelepasan plasenta tidak lama. Hasil analisis uji statistik chi square diperoleh nilai p lebih kecil 0,05 bahwa H0 ditolak artinya ada hubungan antara usia ibu dengan kejadian lama pelepasan plasenta pada kala III dengan OR 5,7 maka usia ibu yang beresiko akan menyebabkan kejadian lama pelepasan plasenta 5,7 kali lebih banyak dibandingkan dengan usia ibu yang tidak beresiko. Diharapkan para ibu khususnya ibu yang memiliki usia beresiko mengerti bahwa pentingnya melakukan perencanaan persalinan sehingga mencegah terjadinya komplikasi pada saat persalinan khususnya pada masalah lama pelepasan plasenta. Kata Kunci: Usia Ibu, Lama Pelepasan Plasenta.
