The aim of this study was to assess the association of hypocalcemia at calving with health and performance of Holstein cows and their calves. Data were collected January 1st 2017 to December 31st 2020. A total of 431 lactating Holstein Friesian cows (118 primiparous and 313 multiparous) from a research of hypocalcemia was 2 groups (hypo and non-hypo). The overall prevalence of hypocalcemia was 3.4% for first-lactation cows and 18% for multiparous cows. Lactating dairy cows with hypocalcemia had greater proportion of cows with Retained Fetal Membranes (RFM) metritis and culling within 60 days in milk (DIM), compared with non-hypocalcemia respectively. For the first 2 official milk tests milk yield and components (% fat, % protein on SCC) did not differ between hypo and non-hypo cows. The days in milk at first service, mastitis, dystocia and pregnancy at first service were not different between hypo and non-hypo groups. The proportion of stillbirth, survival at 60 days of age in calves did not differ between calves born from hypo or non-hypo cows. Calves born from Hypo cows had greater incidence of diarrhea (38.3%) than calves born (22.3%) from non-hypo cows. The results of this study show that hypocalcemia in calving has significant health implications for both dams and their calves.

Jatropha is a pioneer plant that can easily grow even on marginal lands and has high potential as an oil-producing plant for renewable fuels. This plant is an annual plant that can grow until the age of 50 years, in the form of a bush and begins to produce at 6 months after planting with a productivity varying from 0.5 to 12 tons/ha/year with an oil yield of 25-30% and maximum production will be achieved after planting. Plants 4-6 years old. Jatropha has the potential to become an alternative energy source and become a biofuel with renewable energy sourcesor renewable green energy; in addition to other benefits in traditional medicine for various types of diseases. The purpose of this study was to determine the increase in the initial growth of Jatropha cuttings by giving organic growth regulators. Based on the results of the study, it can be concluded as follows: There was no significant interaction in the treatment combination between the concentration of organic growth regulators and the factor of internode location on all dependent variables observed in the early growth of Jatropha stem cuttings. The internode location factor showed a significant effect on the variable number of leaves, shoot length, root length, number of roots, root wet weight, root dry weight, and the location of the 12th internode (R2) gave better results than the 10th internode location. (R1). The concentration factor of organic growth regulators also showed a significant effect on the variables of leaf number, shoot length, root length, root number, root wet weight, root dry weight and K2 treatment (5 ml per liter of water) gave better and more efficient results. compared to other treatments.

Leonardite is a common mineral that contains a lot of organic matter. It may have a beneficial influence on plant growth and nutritional content. The objective of the present study was to determine the effect of four different leonardite doses (0, 20, 35, and 50 g kg-1), three different phosphor rates (0, 50, 100, and 150 mg kg-1P), on plant growth, and nutrient uptake of Cucumber (Cucumis sativusL.). plants. The experiment was conducted in a plastic house. Increasing the leonardite dose statistically increased the concentrations of N, P, K, Mg, Cu, and Mn in the cucumber leaves, but Zn content (34.711 a) mg kg-1of the leaves was significantly higher only with the (20 gm) of leonardite. The highest phosphor application (150 mg kg-1) increased leaf N, P, K, Ca, Mg, and Mn concentrations compared with the other three doses and also the leaf Zn levels statistically did not increase as the P applications increased from (control to 150 mg kg-1). Based on the number of fruits per plant, the best interaction among leonardite doses and phosphor rate were a combination of the (35gm×100 mg kg-1) increasing the numbers of cucumber per plant (48.000a).

Alcohol factory waste which still contains a number of nutrients when enriched with manure is good enough to increase the growth and yield of chili. This research was conducted in Jengglong, Jatisobo Village, Polokarto District, Sukoharjo Regency which took place from September 2019 to January 2020. This study used a completely randomized design with two factors and three replications. The first factor consists of 3 levels of Liquid Organic Fertilizer: waste alcohol + EM4, waste alcohol + EM4 + goat manure, alcohol waste + EM4 + a combination of 3 manure (chicken, goat, cow). The second factor dosage of liquid organic fertilizer consists of 4 levels: 0, 1000, 2000, 3000 l/ha. The results of the study showed that the kind and dosage of liquid organic fertilizer enriched with manure did not significantly affect the growth and yield of chili, but the interaction of the two treatments had a significant effect on the yield of chili. The highest weight of red chili was obtained in the treatment of waste alcohol + EM4 + a combination of 3 manure (chicken, goat, cow) with a dose of 3000 l/ha. In conclusion, the use of alcohol waste for fertilization, especially chili plants, should be combined with manure in order to obtain maximum results. The implication of this research is that for fertilizing chili plants, it is better to use alcohol waste, EM4 and a combination of chicken, goat and cow manure at a dosage of 3000 l/ha.

This study applied Completely Randomized Design (CRD) with 5 treatments and 5 replications. The treatments consisted of J0 = skim milk-egg yolk; J1 = skim milk-egg yolk + jamblang leaves extract 0.2%; J2 = skim milk-egg yolk + jamblang leaves extract 0.4%; J3 = skim milk-egg yolk + jamblang leaves extract 0.6%; and J4 = skim milk-egg yolk + jamblang leaves extract 0.8%. The parameters observed in this study were the percentage of motility and viability of frozen semen of Aceh cattle. The data obtained were analyzed using Analysis of Variance (ANOVA) and if differences were found, then it would be continued with Duncan's Multiple Distance test. The results showed that the addition of jamblang leaves extract in egg yolk skim milk significantly affected the percentage of motility during pre-freezing and post-thawing, significantly affected spermatozoa viability during pre-freezing and significantly affected the spermatozoa viability during post-thawing. J3 treatment (jamblang leaves extract 0.6 gram/100 ml) it should be higher than the other treatment, where the percentage of motility at pre-freezing and post-thawing were 55.48% and 52.71%, respectively, and the percentage of viability during pre-freezing and post-thawing were 56.59% and 53.94%, respectively. It was concluded that the addition of jamblang leaves extract in the skim milk-egg yolk extender affected the percentage of spermatozoa motility and viability of Aceh cattle during pre-freezing and post-thawing.

For controlling the entire drying process of a material, it is crucial to understand the moisture ratio of the material in the drying process. In order to ascertain the moisture change rules of kelp knots in the solar-heat pump combined drying process, an analysis was made on the impacts of different drying temperatures, wind speeds and loading capacities on the drying rate in this research; meanwhile, three common drying dynamic models were selected and compared to know their applicability to the solar-heat pump combined drying of kelp knots. Further, the model coefficient was determined and the optimal model was obtained. The results reveal as follows: drying temperature, wind speed and loading capacity have significant impact on and significant correlation (P<0.05) with the drying rate of kelp knots; under different drying conditions, the drying rate is always high in the early stage, lowered and gradually moderate in the later stage. After fitting the drying dynamic model, it is found that among the experimental data, regression coefficient (R2) is the largest in the Verma model, and the sum of squares for error (SSE) and root mean square error (RMSE) are low. This indicates that the Verma model can be used to accurately express and predict the change rules of moisture in kelp knots during the solar-heat pump combined drying. According to Fick's second diffusion law, the effective diffusion coefficient Deff increases with the increase in drying temperature and wind speed, and decreases with the increase in loading capacity.
