Seminal plasma mengandung mikro mineral seperti seng (Zn) dan tembaga (Cu) yang diperlukan untuk kualitas sperma. Namun, informasi mengenai hubungan mikro mineral dengan kualitas sperma pada sapi aceh masih terbatas. Penelitian ini bertujuan untuk mengetahui hubungan antara kadar mikro mineral Zn dan Cu pada seminal plasma dengan kualitas semen sapi aceh. Sampel seminal plasma berasal dari lima ekor sapi aceh jantan di BPTU-HPT Indrapuri berusia 4-6 tahun dengan bobot badan berkisar 300-450 kg. Sampel semen dilakukan evaluasi kualitas semen secara makroskopis dan mikroskopis kemudian dilakukan pengukuran kadar mikro mineral Zn dan Cu seminal plasma menggunakan metode Atomic Absorption Spectrophotometer (AAS, PerkinElmer AA-600). Data dianalisis secara deskriptif dan diuji menggunakan korelasi Pearson’s. Hasil penelitian menunjukkan bahwa kadar Zn pada seminal plasma berkorelasi positif dengan motilitas (r=0,041) dan konsentrasi (r=0,159) yang termasuk dalam korelasi lemah, sedangkan Zn berkorelasi negatif dengan abnormalitas dengan korelasi kuat (r=-0,763). Kadar Cu berkorelasi negatif dengan konsentrasi (r=-0.211), motilitas (r=-0,515) dan abnormalitas (r=-0.140) dengan korelasi lemah sampai sedang. Hasil uji statistik menunjukkan korelasi antara Zn dan Cu dengan kualitas semen tidak signifikan (p>0,05). Disimpulkan bahwa, kadar Zn dan Cu pada seminal plasma tidak berkorelasi secara signifikan dengan kualitas semen sapi aceh.

Seminal plasma contains microminerals such as zinc (Zn) and copper (Cu), which are essential for sperm quality. However, information regarding the relationship between these microminerals and sperm quality in aceh cattle remains limited. This study aimed to determine the relationship between Zn and Cu concentrations in seminal plasma and semen quality in aceh cattle. Seminal plasma samples were collected from five aceh bulls aged 4–6 years with body weights ranging from 300 to 450 kg at BPTU-HPT Indrapuri. Semen samples were evaluated macroscopically and microscopically, followed by the measurement of Zn and Cu concentrations in seminal plasma using the Atomic Absorption Spectrophotometer (AAS, PerkinElmer AA-600). Data were analyzed descriptively and tested using Pearson’s correlation. The results showed that Zn concentration in seminal plasma was positively correlated with motility (r = 0.041) and concentration (r = 0.159), both classified as weak correlations. Zn was negatively correlated with abnormality, with a strong correlation (r = -0.763). Cu concentration was negatively correlated with concentration (r = -0.211), motility (r = -0.515), and abnormality (r = -0.140), showing weak to moderate correlations. Statistical analysis indicated that the correlations between Zn and Cu concentrations and semen quality were not statistically significant (p > 0.05). It can be concluded that Zn and Cu concentrations in seminal plasma are not significantly correlated with semen quality in aceh cattle.
