Abstract

Tujuan penelitian ini untuk mengetahui pengaruh pemberian pupuk bokashi sludge biogas daun Chromolena odorata dengan level yang berbeda terhadap pertumbuhan tanaman lamtoro tarramba. Penelitian ini dilaksanakan di Kelurahan Kawangu, Kecamatan Pandawai, Kabupaten Sumba Timur yang berlangsung selama 6 bulan di mulai dari bulan Desember sampai Mei 2022. Adapun rancangan yang digunakan yaitu rancangan acak lengkap (RAL) yang terdiri dari 5 perlakuan dan 4 ulangan, P0 = tanpa pupuk bokashi (kontrol), P1 = pupuk bokashi (200) gram/polybag, P2 = pupuk bokashi (400) gram/polybag, P3 = pupuk bokashi (600) gram/ polybag, P4 = pupuk bokashi (800) gram/polybag. Parameter yang diteliti dalam penelitian ini yaitu tinggi tanaman lamtoro, diameter batang tanaman lamtoro, jumlah tangkai daun dan jumlah helai daun. Dari hasil penelitian disimpulkan bahwa perlakuan P1 (level pupuk 200 gram/polybag) sudah cukup baik untuk memenuhi kebutuhan pertumbuhan awal tanaman lamtoro.

Abstract

This study aimed to determine the effect of body weight on scrotal circumference in Bali bulls. Bali cattle are one of Indonesia's indigenous genetic resources with high adaptability, good productivity, and an important role in national beef production. The study employed a descriptive method through observation and evaluation of exterior performance. The research sample consisted of 10 Bali bulls grouped by age, namely 1–2 years and 3–5 years, with five animals in each group. The parameters observed were body weight and scrotal circumference. Body weight was measured using a manual scale, while scrotal circumference was measured using a measuring tape at the largest part of the scrotum. Data were analyzed using regression and correlation analyses with IBM SPSS version 25.0. The results showed that the average body weight of Bali bulls was 260.80 ± 7.80 kg, while the average scrotal circumference was 25.60 ± 3.27 cm. Regression analysis revealed a very strong positive relationship between body weight and scrotal circumference, with a correlation coefficient (r) of 0.976 and a coefficient of determination (R²) of 0.952. These results indicate that 95.2% of the variation in scrotal circumference was influenced by body weight, while the remaining 4.8% was affected by other factors such as age, genetics, nutrition, health status, and management practices. The regression equation obtained was Y = 250.054 + 5.910X. Based on the findings, it can be concluded that body weight has a highly significant effect on the scrotal circumference of Bali bulls. An increase in body weight is associated with an increase in scrotal circumference. Therefore, body weight can be used as one of the selection criteria for superior breeding bulls to support the improvement of productivity and genetic quality of Bali cattle.

Abstract

This study aimed to determine the relationship between Body Condition Score (BCS) and testicular size (length) in male Bali cattle. The research method employed was quantitative correlational using simple linear regression and correlation analysis. The research sample consisted of 8 male Bali bulls aged 2 years old, categorized into variations of BCS groups 2, 3, and 4. Data collection was conducted through visual assessment and palpation to determine the BCS status, alongside macromorphometric measurements of testicular length using a measuring tape. The results showed an average BCS value of 3,000 ± 0,756. Based on the BCS grading scale of 2–4, a BCS value of 3 indicates that the Bali bulls were in ideal condition. Meanwhile, the average testicular length obtained was 8,813 ± 1,033 cm, reflecting normal and uniform growth of the external reproductive organs for the 2-year-old age group. Based on the simple linear regression analysis, the regression equation was formulated as Y = 6.188 + 0.875 X with a correlation coefficient (r) of 0.640, indicating a direct (positive) relationship with a moderate-to-strong level of closeness. However, the significance test showed that the relationship between the two variables was not significantly different or non-significant (P >0.05) since the calculated r-value (0.640) was smaller than the table r-value (0.707). The study concludes that 2-year-old male Bali bulls exhibit proportional body condition and normal testicular length with a positive-linear relationship, though its statistical effect is non-significant. This proves that the development of testicular size is not solely determined by temporary physical body condition but is strongly influenced by other internal and external factors such as genetics, age, body weight, and environment. Therefore, BCS assessment is suggested only as an initial indicator, while the selection of superior bulls must still be carried out comprehensively by involving other reproductive morphometric parameters.
