Breeders with superior genetics will pass on the gene to the next generation. Efforts to improve the genetic quality and livestock population require selection of breeders to improve good livestock performance. This study aims to determine the comparison of livestock body size with the size required in SNI and the comparison of buffalo with intensive and semi-intensive maintenance systems. This study used a purposive sampling method for sampling. The samples used were pregnant and lactating breeders in Kejambon Village and Surajaya Village. Differences in maintenance systems for female and lactating breeders were analyzed using the t-test. The results showed that the Body Scoring Condition (BCS) value was not significantly different (P>0.05). The body size of pregnant female breeders showed a significant difference (P<0.05) except for shoulder height and body weight. While in lactating female breeders, all parameters were not significantly different (P>0.05). The conclusion is that BCS observations show that pregnant and lactating breeders that are intensively and semi-intensively maintained meet the standards as breeders. In the morphometric measurements of the body of female and pregnant breeders that are intensively and semi-intensively maintained, all meet the standards in SNI. The morphometry of pregnant sows kept intensively was higher than that of semi-intensive sows, while that of lactating sows kept intensively was lower than that of semi-intensive sows.

Pemetung Cave is located in Padang Bendar Village, North Bengkulu Regency, surrounded by dense foliage with a river flowing near the cave. Based on surveys, the cave is inhabited by a colony of bats, and this research is important because bats have an ecological role in maintaining the balance of the cave ecosystem. This study aims to inventory the types of bats inhabiting Pemetung Cave. The research was conducted using observation methods and direct bat capture within the cave using hand nets. The results showed 15 adult bats and 2 juvenile bats, consisting of 6 males and 11 females. Identification based on morphological characteristics indicated that all the bats were of the species Hipposideros larvatus. Morphometric measurements ranged from 40.4-76.0 mm for body length (HB), 47.7 mm for total body length (TL), 8.9-29.4 mm for tibia length (T), 32.5-64.6 mm for forearm length (FA), 7.3-21.4 mm for ear length (E), and 7.3-14.1 mm for hindfoot length (HF). Pemetung Cave provides a good shelter for Hipposideros larvatus bats, thus serving as a roosting site.

Sunlight is one of the crucial factors that can affect plant growth, including mung beans (Vigna radiata), which are an important agricultural commodity in Indonesia. This study aims to examine the effect of sunlight exposure duration on the early growth rate of mung beans (V. radiata) local variety from West Sumatra. This research is a quantitative experimental study with treatments including four sunlight exposure durations: control (no light), 4 hours (P1), 6 hours (P2), and 12 hours (P3) per day. The study is designed in a completely randomized design (CRD) with 4 replications. The observation parameters in this study include plant height, number of leaves, and leaf width as the main parameters. The results showed that the duration of sunlight exposure significantly affected the number of leaves during the early growth phase of mung beans, but did not significantly affect plant height and leaf width. The 12-hour sunlight exposure (P3) provided the best results, with an average plant height of 10.65 cm, 5 leaves, and a leaf width of 2.05 cm. Therefore, adjusting the duration of sunlight exposure is crucial, especially in increasing the number of leaves that contribute to the plant's initial photosynthesis process. These results can serve as a basis for determining the optimal light duration for the cultivation of mung beans in the early growth phase.

Corn (Zea mays L.) is an important commodity as a source of carbohydrates in Indonesia, so proper fertilization is needed to increase its productivity. This study aims to determine the comparison of the effectiveness of cow manure and urea fertilizer on the growth of corn plants. The method used is an experiment with a Completely Randomized Design (CRD). The parameters measured include plant height and number of leaves. Based on the results of the study, the application of cow manure gave significant results on plant height and number of leaves of corn plants compared to urea fertilizer. The treatment of giving cow manure with a dose of 12 g/plant had better plant height and number of leaves compared to other treatments. The conclusion of this study is that the application of cow manure has a significant effect on plant growth and has the potential to be more effective in increasing the vegetative growth of corn plants.
