Abstract

This research was conducted to determine the effect of the use of Gonadotropin Releasing Hormone (GnRH) and Vitamin E-Selenium on cows experiencing reproductive disorders in the form of repeat breeding. This study used 20 repeat breeder beef cattle which were divided into 4 groups and 3 treatments and 5 replicates: P0 (control), P1 (AI+GnRH 5 ml), P2 (AI+Vitamin E-Selenium 20 ml), P3 (AI+GnRH 5 ml+Vitamin E-Selenium 20 ml). The NRR and CR data obtained were analyzed using the Cochran's Q Test, which if the test showed a real effect, the Pairwaise Comparison test would be continued. The results of the study stated that there was no real effect of the combination of GnRH hormone and Vitamin E-Selenium on the success rate of Artificial Insemination in repeat breeding beef cattle (P>0.05). In the P3 treatment, the pregnancy rate was 80% and P1 also produced the same pregnancy rate, which was 80%. This figure is higher when compared to the results of P0 which is 0% and P2 which is 40%. Based on the four groups and 3 treatments, it can be seen that the addition of a combination of GnRH and Vitamin E-Selenium injection has a higher influence in terms of the percentage of pregnancy, Non Return Rate and Conception Rate produced. This is because GnRH is able to induce a pre-ovulation LH surge. Increased LH concentrations promote oocyte maturation, induce ovulation and can improve the function of the corpus luteum.

Abstract

This study aims to determine the effect of the addition of Organic Fertilizer (OP) made from oil palm plantation waste and cow dung enriched with Agricultural Symbiotic Microbes (ASM) on Sorghum (Sorghum bicolor) production. This research was conducted in Natai Raya Village, Kumai District, West Kotawaringin Regency, Central Kalimantan. The design used was Randomized Complete Block Design (RCBD) consisting of 4 treatments P0= control (100% NPK fertilizer), P1= NPK fertilizer 100%+OP 50% (100 g/plant), P2= NPK 100%+OP 100% (200 g/plant), P3= NPK 100%+OP 150% (300 g/plant). The number of sorghum per plot was 24 plants, and the number of plots per treatment was 3 plots, with a size of 3x2 m (6 m2). Harvesting age of sorghum was 70 days. Parameters observed: plant growth (plant height and number of tillers), and plant production (fresh weight and dry matter). The results showed that the average height of sorghum plants were:  P0 = 181.14 cm, P1 = 204.35 cm (increased 12.81% compared to PO), P2 = 211.81 cm (increased 16.93%), and P3 = 218.79 cm (increased 20.79%). The number of tillers of sorghum plants were: P0= 10.47 stems, P1= 10.53 stems (increased 0.53%), P2= 10.74 stems (increased 2.52%), and P3= 11.01 stems (increased 5.1%). The fresh weight production of sorghum plants and fruits per plot was P0= 13.4 kg or 22.36 tonnes/ha, P1= 17.1 kg or 28.52 tonnes/ha (27.55% increase), P2= 17.5 kg (30.63% increase) or 29.21 tonnes/ha, and P3= 18.2 kg or 35.75 tonnes/ha (35.75% increase). The dry matter production of sorghum plants and fruits per plot were P0= 4.17 kg or 6.94 tonnes/ha, P1= 5.31 kg or 8.85 tonnes/ha, P2= 5.44 kg or 9.07 tonnes, and P3= 5.66 kg or 9.43 tonnes/ha. The conclusion of this research is that the addition of organic fertilizer as much as 150% or 300 g/plant gives the best results on the growth and production of shorghum plants.   Keywords: Growth, Production, Shorghum, Organic Fertiliser, Oil palm plantation waste and cow feces.
